Thanks for watching! Please consider subscribing to my new channel here: www.youtube.com/@jamminpcs. I'm trying to move the easier hardware stuff there so that I can focus on the more in depth troubleshooting and diagnostic videos here :)
Thank you! I worked on this for over an hour and watched six different videos. If you had not said something about the voltage and amps, I never would have looked. Then I noticed I was using a dell charger on an HP laptop. And the voltage and amperage were slightly different. I rummaged in a box and found the HP charger and it works!
Correction: the amperage on your charger should be higher than what your laptop draws, voltage is the requirement and the current will be modulated (not drawn to the max of the charger). Using a charger with max amperage capacity of less than your laptop requires may damage the charger.
Great vid, informative and easy to follow. Do you have any videos on taking the top off ? I have an hp laptop that has the exact issue with a bad port. Did all the other tests up to that, and 100% positive it's a bad port.
Cool videos, thank you! I have two type c charger ports in my chromebook and ligths didn't work on both, i assume it's not likely both of them broke down?
No, not likely. 1. For a computer that does not turn on, try this video first; ua-cam.com/video/HHwzA37r4e8/v-deo.html. Let me know how that goes :) 2. Also, did anything happen before this issue appeared? Liquid spill, overheating, Windows update, etc?
Your videos are awesome, thanks. Very clear and extremely helpful. I've got no charging on an Asus R556LA. My cord works (putting out 19v), and I've replaced the battery, which will turn the unit on, but it's still not charging. I'm suspecting the power jack, so I've ordered a new one - any tips/instructions on how to replace? Is it soldered into the board, or will just snap in? Any help much appreciated. Thanks.
It depends on the computer. I dont have one of those in my shop and cant find a motherboard access video online :( So it would depend on what you see when you open it up. Most computers however, will have it soldered on
Elaboration and question -> I think the power jack or power supply has a problem on the hand me down laptop I just received that didn't turn back on (battery is a goner, so I'm depending on direct wall connection). Already separated from the motherboard, a multimeter applied to the -power jack connector- while the P.Supply is plugged into the wall will show 19.5V, but moving the cord/jack around where it's plugged in on the PowerSupply side causes huge fluctuations. Stop moving cord, stabilizes IF in certain positions. I tried attaching jack port back into motherboard so I could see if the motherboard side is receiving the 19.5V (when stable), but my motherboard does not have an end like yours to apply power/ground probes to - it is mounted vertically, rather than horizontally to the motherboard (your example being horizontally mounted/attached), and the other end of the motherboard at that location HAS 4 soldering points representing the 4 (2 black, 2 red) positions of the jack port on the other side. When I try to place my probes on these soldering points, I get an extremely low voltage reading that doesn't change. I'm not sure if I'm supposed to see full voltage at these soldering points or not. What do you think? (I ordered a new jack port and power supply plug on Amazon thinking I could just return them if it doesn't correct things)
To clarify something else too - the power supply jack doesn't fluctuate on its own (while not connected to removed jack port) but it's very hard for the red probe to find a spot where it gets voltage.. hence why I decided to remove the jack port and test them together).. because it seemed really difficult to get the voltage, and there is a missing chunk of plastic on the jack end, but I still wasn't sure if it was bad or not.
I followed instructions on video (very helpful) have completed processes for eliminating static, have done driver and BIOS updates and still me Dell 5559 inspiron will not recognize the charger and the battery won't charge. Unfortunately I have drained all my batteries so I can't continue to do other diagnostics. Is it possible that I need to replace the mother board? Concerned about buying a new one if there are other causes for this problem. Any guidance is greatly, greatly appreciated!
Great video!! I have a question. My laptop discharge very quickly when i unplug the jack. In this case the problem is the jack or the battery? Thank you! You're amazing!
Thank you very much for this video. I am learning a lot here, how to use a multimeter and test laptop charger and the power jack. God bless you for sharing this information.
Very good. Very informative. Ironically the laptop your performing on is the EXACT one i have. I followed your steps... power adapter good/ getting power from MB/. Maybe I’ll go to the other video -bios reset? Not sure. Voltage is spot on with your readings too... this was the first time i used this laptop in 3 years. Any suggestions would be greatly appreciate. Keep up the good work. Thx bud!
PC Monkey yeah sir! Correct. I have an older Hp 15 - F9H96UA. But... upon further investigation AND more importantly looking through all your vids... i noticed the power supply(button) on the back has a wire strip break off (solder)... sucks cuz i dont have another replacement part or strip. After putting in Bio battery (from ur video). You said something at the end which i hope everyone takes heed.... you said, “ make sure all your connections are good”... great advice bro! And this is after 3 times i fully disassembled the dam thing. I’ll keep you posted. Any comments, ?’s, or complaints are highly welcomed. Thx bud!
Thank you so much for this tutorial :). I also i tested the pins on the power jack and all of the wires are transmitting the correct voltage except for one wire, which isnt transmitting any power at all. should i replace it? Also I have a dell inspiron 5491
Hi first let me congratulate you, for your fantastic videos, thanks to them, i already make some advances in my pc diagnostic. I have an hp Envy 17-s143cl laptop. This laptop do not start, whith the battery or with the power charger cable. When i connect the power charger cable, the little light at the power jack connector side, do not bright. And when i press the power buttom, no light, no fan, no sound neither. Now if i already checked that the the charger, the power jack and the power jack port have 19.4 volts, what need to be my next step? Is the mother board failing? Please, do you have another video, that i can follow? Thank you, very much for your help!
Just watched the Video's very good. Not being a Technician, if I buy the Connector part which is not expensive, can install myself. Does it entail just unplugged the old and in plugging the new. HP Diagnostics said the connector / adaptor passed the test???. Its either that part or I'm stumped its still reading 4%. Now I know where the hidden screws are to remove the cover I will suck all the dust out and pull out the connector device and then plug back in???
Yes, usually the power jack is not a very expensive part. If your power jack is on its own board, it would be a simple matter of removing the board and replacing it. However, many power jacks are now a part of the motherboard and not on their own board. In that case, it would be a matter of replacing the motherboard or un-soldering the power jack and soldering on a new one. I dont understand the last question.
Hi, I have similar problem and came across your video, it was really helpful. But i have a doubt, hope you can help me. From last few months my laptop don't turn on if i leave all night plugged in or also if i forgot to pull out the charger after shutting down.. next time it wont turn on.. this keeps happening i assumed its static and followed your previous to remove static build up.. but this time it didn't work out .. so i bought a multimeter, new power jack and a new button switch .. thinking these could b the problem first i checked the power supply in charger and power jack with multimeter both gave me 19.5V ..perfectly fine But when i about to check the power passes to the motherboard, i thought to match black with black and red with red.. but it gave a spark.. when u say put red on metal bracket..what does it mean ? and I haven't separated the motherboard it is still in place. do u recommend to remove separately and check it ? .. and can u tell me at what plave should i place multimeter red port .. and what is metal bracket ??
You dont have to remove the motherboard if you can easily access the power jack without needing to do so. Every power jack is different. They are not all the same so I cant tell you exactly how to test it. What is the model number of your laptop?
Really am very greatfull for this video i learned very perfect from you .. Thanks for your video... Its helps to whom learn BASIC electronics... Tank you so much brother
Assuming you've checked the charger and everything else. Using your voltage meter what should the reading be in the battery port. I think i have the same model in your video and I have 8 prongs on the back of the laptop. 2 Neg (bigger) 6 Pos(?). I get readings from all 6 Pos except one no matter which Neg prong I touch to.
I’ve binged watched a bunch of your videos I love how clearly they explain everything. I’m only stuck on one issue. My charging port doesn’t look like it can disconnect it looks like it’s soldered to the motherboard. How do I check with the multimeter if it is receiving power? I used the tutorial to check the charger and the charger is good!
The powerjack should submit power to the motherboard through one main pin. Towards the middle of the rear of the port. That is where the charge should be read. You can put the black connector on the outside of the metal. That would be ground. Does that make sense?
@@tigara1219 Try both but the Red should go onto the metal component you believe to be the power or the live power transfer pin. The Black should just go on a ground. Does that make sense?
PC Monkey wow you are excellent at explaining things I am a total noob and I understood that 🤣 Cable has power. Charging port has power. Still won’t turn on 🤦🏽♀️ What the actual heck
@@tigara1219 And you have already tried the first video testing the Battery, Charger, and trying a Static Discharge? And you tried the second video trying a BIOS Reset? If the Charger and Jack check out here then your left with needing a Motherboard replacement at this point :( That could be fun :) And depending on your computer, it may be cheaper than you may think. Need help locating a Motherboard?
very helpful. my dell laptop e6530 charging jack has 2 red wires, 2 black wires and a blue. one set of black and red gives me correct voltage, but the other sets are off. are any combination of red and black supposed to give me the 19 volts?? thanks.
i have HP brobook 650 G1 some water fall in the Specker and the power Butten after a 3 days its work but when i but the charger and leave it in the laptop its not work . what you think its Borken ?
Thanks! That's for laptops with a detachable power connector. But when is onboard... any ideas? Tired of looking for the schematics of my Samsung np700
I think a surge of power from one of the batteries or from not draining other components when replacing a screen on a Dell Inspiron 1500 fried something and now it won't turn on at all. Went through both this video and previously went through the "drain the power for 60 seconds and test battery and power adapter video" and also the unplugging the BIOS battery for awhile, and I can confirm correct power is getting TO the motherboard, but that's as far as I can get. If power gets to the motherboard, what's the next thing to check? (Do I have to test anything regarding pushing the power button on to know where the power goes next?
Hello, great video! Ive test my charger, the power jack and the port and they all read 19 volts. Laptop doesn't charge and doesnot turn on when the battery is removed and computer is plugged in. What could be my next step?
@@PC_Monkey Just watched ot and followed all the steps removing and placing back in ram etc. In a wierd accident, while plugged in to the wall and computer, the charger cable melted on a stove burner and i could see that the raw wire of the different cables were touching. I have a new charger now with the same power ratings. After that accident the battery stopped charging but the computer ran just fine untill i ran out of charge.
after i intalled windows 10 in my lenovo color orange ultra book... it finished.. i updated it. and so on so fort.. then when i was trying to turn on it again... it wont turn on... it just blinks.. the keyboard and the led light.. just blinks.. on and off.. about 3 sec.. what must be the problem.. i was so happy when i finished it then suddenly awts
Did you get a voltage reading when you tested the white wires with + red wire? My laptop power jack has a single white wire which does not register voltage with + wire. The black and red wires are fine showing 19V. My laptop will not turn on with good AC power adapter (tests at 19V).
The white usually will not show a charge. The red should. For a computer that will not turn on, have you tried the steps seen here? ua-cam.com/video/P3I7dDpkJps/v-deo.html.
@@PC_Monkey Thanks so much for replying! Yes, the red is + and black is -. When, with power connected, I touch both with the meter leads, I get 19V. When I touch the red and the white I get no voltage. I assumed white functioned as ground and meter should register voltage with the red wire. But it doesn't. My laptop does turn on and functions properly on battery. It does not turn on with battery disconnected and AC power adapter plugged in. When the computer is on, the power adapter will not charge the battery. The power adapter is good--supplies 19V. The weird part is sometimes the battery will charge up but only if the laptop is completely turned off! I did try resetting the bios by removing the CMOS battery as you suggested in the other video, but no luck. Something funky is going on and I really like my EVGA SC17 laptop!
Any videos on testing power at the mother board or if all is good to this point just need to replace the motherboard ? I've seen something about replacing an IC or PD1 in the adapter section of the motherboard but have no idea how to test or where to get such... This is Dell inspiron i7 5770, where battery is not charging sadly 😢
Yes, you can test into a motherboard and hopefully find the component that is faulty. That would then be replaced. But no, I dont have any videos on that level repair. If my motherboards need to be repaired to that extent, I find it faster and easier to replace the board. Sry :(
Hello!!Thankyou for this informative video. Yesterday,my laptop got discharged in the normal way. I tried to charge with my charger n then with my friend's charger ,it didn't work. After that, I removed the battery n connect the charger again.Now, the charging light lit up for a second n then it gets disappeared ,therefore what could be the problem in this case .I am looking forward to your reply
same issue with my laptop, but if I try to push and bend my charger near the pin then my laptop turns on and everything was well. But then when there was sudden power outage and I restart my PC then I need to bend and find the right bend again before it works. It's tiring.
Hi Thank yu so much for the explanations. I did all the steps. Adapter OK. Charging Jack OK. Charging port does not transmit the incoming DC20V on to the motherboard. What can I do next? Please help.
You said the charging port does not transmit the power to the motherboard? If so, you found your issue. You can install a new port or swap out the motherboard if thats not possible
@@PC_Monkey well thanks but how to install a new port. It seems the port is soldered on to the board. Am working on Lenovo Ideapad 110-15ISK Model 80UD
Question I have a mini desktop that when I plug in the ac adapter the power light on the ac brick turns off. Motherboard power port has 4 leads and then five pins that go to the motherboard . All pins register continuity is that normal?
I have disassembled a MIIX 510 which doesn't turn on or charge. The power button will spin the fan for 1 second only.The charger gives correct 20V, tested with a DMM. However when I plug in the charger, I always see a super tiny blue spark - this can't possibly be normal can it? You wouldn't notice it briefly sparks unless you had it disassembled, as I have. It also sometimes sounds like coil whine on the board. Would appreciate quick thoughts, thank you.
For a computer that does not turn on, try this video first; ua-cam.com/video/P3I7dDpkJps/v-deo.html. Let me know how that goes :) If your seeing a spark, that could indicate a damaged power jack / motherboard :(
@@PC_Monkey thanks so much for your reply, but having watched your linked video, I have previously tried all suggestions within. I also previously tried my Multi meter on the charger which reads solid 20.33v (rated 20v) so I assumed that was fine, but I saw a video by Sorin last night which says the charger may read correct volts but may still have an un-testable current issue.
Hello! My battery does deliver power to my motherboard, but my ASUS laptop is still dead with no lights turning on. I’ve followed your instructions and gone through the videos in the description. What should I do?

Hi nice video,my laptop suddenly cant power on even getting power to wall. my question is my reading for dc adapter is 19.81v so when i plug in to my jack board its turn to 17.14v,its normal or suppose to be the same? I see the back of my machine is 19.5v 7.7A. thanks!

Hi I've watched both your videos for power adapter and now this. All 3 are raiding same voltage 19.6 the power adapter is 19.5. Still no power going to my laptop and turns on. What could the issue be? Thanks
I’ve tried all of these videos but it still isn’t working all that happens is the power light turns on for a sec then off. The charging light blinks a really slow orange. Do you think maybe the mother board or CPU is the problem? Any help would be much appreciated thank you for the vidz!
Thank God you are back!!! Your vids are the BEST. I had 3 of them saved, finally had a block of time to work on the lappies, undisturbed and POOF! Vids were gone.

Thanks for the nice thoughts :) Ya, an error erased all our videos :( Fortunately, we had most of them saved and are uploading them again and putting up more. Thanks for missing us :):):)
If your power jack is on its own board then you can simply replace that board. If its part of the Motherboard, then you would have to either de-solder and remove it, then solder on a new one, or replace the motherboard.
Hi! I have an Ideapad L340-17IRH Gaming Laptop (ideapad) - Type 81LL. The charging port doesn't work (i have to wiggle my power cable for it to start charging). However, now, nothing works and I can't turn it on at all! Lenovo says it's "my fault" and it will cost me loads to have it fixed. Is it easy to disconnect and reconnect a new port? THanks¨ Virginie
1. For a computer that does not turn on, try this video first; ua-cam.com/video/kOBY4k2Mn_k/v-deo.html. Let me know how that goes :) 2. Yes, if the Power Jack is loose like that, most likely it needs to be replaced. You can install a new Power Jack, replace the motherboard that its a part of, or hire someone to do it as your best bets.
Your videos are awesome, thanks for the great content of your channel. About this video, I have an issue that's driving me crazy and I would really apreciate if you help me on giving me some directions. It's a Dell Inspiron 15R SE 7520. The charger wasn't charging the battery and the laptop won't turn on with the charger plugged in w/o battery. It was working only with battery and no charger. I did the 1 minute power on w/o battery nor charger to drain the static electricity after watching one of your videos (thank you again for the great content) and the problem was solved. I had the laptop being charged and working with the charger plugged in with or w/o battery, all perfect. But today, 2 days after fully working, it's happening again. And worse: the 1 minute static dischage procecure doesn't help anymore. I've checked the charger with multimeter and it's ok. I even tried another charger (same specs), no success at all. Right now the laptop works (perfectly) with the battery but the charger does not affect it at all. After watching this video, I've tested the power jack and there's something confusing me: the charger's output is 19.5V / 4.62A and those 19.5V are shown in my multimeter display when I test the charger plug. But when I connect the charger to the power jack, as you show in your video, the multimeter shows only 18.5V maximum. Could this be the problem? Sorry if I bother you with this, but I'm about to get crazy. Thanks in advance!
@@PC_Monkey Thanks for the answer. No, the charger does not charge the battery even with the laptop off, I've just tested it (30 minutes off with charger plugged in). Also, when I enter the diagnostics mode (pressing F12 and selecting it), it says "Warning: Charger is not detected...". I've also disassembled it, cleaned the boards, changed thermal paste, etc., the problem persists.
@@Zimerer Its saying the charger is not connected to Id like to assume its the charger. Is the charger generic or brand name Dell? If generic, replace with a brand name. Dell is really annoying about that. If its a brand name already and you tested to make sure its working, I am starting to think perhaps motherboard issues at that point :(
@@PC_Monkey The charger is brand name Dell, the one that came along with the laptop from Dell. Thank you very much for your kindness and all the help. God bless you!
Hey im runnin into an issue with my acer aspire 5. The battery is not chargin, i took it out, it opens with the ac in but when the cpu goes on higher % it just shuts down. Idk if it can be the ac or the power plug. The ac has 19v output 🤷♂️ could the plug be the reason. Before all these my baterry kept disconecting the ac from chargin till it did not charge it at all now.
Hello and thanks for the video. I would like to ask if the bad charging port had its led displaying white while you're testing it or does the led on the charging port only show when it's connected to the motherboard?
Very helpful. Good tip matching the power supply symbol with the multi meter. When I plug my laptop it starts up for a few seconds and stops. Occasionally I see the BIOS screen for a second before shutting down. I've tested my power supply and the connector on the mobo, it's soldered to the board. I've also removed all components, HDD, CPU, RAM, WiFi. I've left the display connected & keyboard. I removed the BIOS battery overnight. Also checked for a loose screw that may be causing a short. Any suggestion?
1. Are you able to find any recovery or restore options in BIOS? 2. Assuming you have an HP computer, can you try the steps seen here? ua-cam.com/video/_qF-oqPrn7M/v-deo.html
@@PC_Monkey I can't get to the BIOS, I only see the BIOS for a second before it shuts down. PC powers on for 2 or 3 seconds and the shuts down. Not a boot loop problem, also not a HP, it's a Samsung. Tried instructions here ua-cam.com/video/P3I7dDpkJps/v-deo.html Thank you for you help
@@rfausey You tried the manual BIOS reset as seen in that video? Also, if you remove the battery and only turn the computer on with the power adapter, does the computer still turn off?

I plugged in a wrong charger with 20 Volts over the charger I was supposed to use. Laptop was still working but then wouldn't charge anymore. Would those symptoms be a sign of a bad battery, ports or motherboard, or too difficult to tell without doing these tests? Any help would be much apprecaited
Its possible the battery is damaged. Your computer is turning on and working fine otherwise? If so, can you try the steps seen here? ua-cam.com/video/arZpfqcVoUs/v-deo.html
In the end I took it to a repair shop, I believe a couple capicitators had blown on the motherboard, so those were changed out and it's working again. Your videos came in handy though self diagnosing so atleast I had some idea of what the problem was. Thank you so much again
Thank you for the video. My laptop fell on its side while plugged into the charger, which caused the charging port to sink into the laptop, I tried pulling it out with a metal clip and it sparked, yet still turned on, cause the battery had some charge in it. After battery totally died and wouldn't charge I opened it up and tried to replace the charging cable connected to the motherboard, and that also sparked when the screw driver I was using touched the top of it. I don't have the tool to test if there's power like you're doing, but do you think the motherboard is gone now after 2 sparks? The new charging cable isn't supplying any power either. Thanks.
Unfortunately, yes after two sparks the motherboard may be damaged. However, to be sure you can start troubleshooting a laptop that wont turn on as seen here; ua-cam.com/video/_MOe71kBPOY/v-deo.html.

For a computer that does not turn on, try this video first; ua-cam.com/video/P3I7dDpkJps/v-deo.html. Have you tried those steps yet? If the power jack is reading just 5V then that may be the issue if none of those other steps help. You may need to replace the power jack if its easy to do so. If not and if its part of the motherboard, you would need to replace that :(
Hello, my laptop suddenly died while I was using it, no charge lights after less than a second I plugged in the charger. It just suddenly powered off. Also I heard a little spark in the power jack area. I already tried plugging it without battery but still no charge light. There is also no burnt smell or any smoke after the spark happened. I wonder if it was a short on mobo or power jack do you have any ideas?
My laptop charges with 130 watt adapter. when i plug in the adapter, the battery icon shows charging but I'm pretty damn sure its not. Can this problem also be referred to the faulty power jack or could there be any other issues?
@@sagarmathapandeya4972 It could be either. I would test both the charger and the jack. Also, try the steps in this video. If nothing works, it could be a Motherboard issue :(
Hi, so a/c adapter tested fine, down to dc jack, where again, I don't know what i'm doing. Mine has 9 wires, from closest to farthest from jack: a single white, then 4 blacks and 4 reds. Does is matter which black and which red I test. Laptop is a DELL G3 17 3779. In any case, I somehow managed to get a 19.xx v reading, so this is not turning out as I'd hope. Tested with original battery and then with brand new battery, a/c adapter tested out ok, as well as dc jack.
What is the issue with your computer? Is it not turning on at all? Are there any signs of life at all? Lights? Fan, Motherboard, or Hard Drive sounds? Anything seen on the screen?
@@PC_Monkey It started out as working fine, but only on AC. In the last 2 days, it seemed to go thru all possible power malfunction schemes. After way too many steps to list here, I somehow managed to get it working like new !
Hello my laptop cant charge.. I can use it only if connected to power socket.. I even try to change battery but will not charge.. It my power jack still the problem if i can use it to on the laptop but not charging?
I have checked everything with your video's.. even power jack is working.. still my laptop is not turning on.. what to do.? Is there any power ic or anything? That i should check
If none of the tests in this video worked; ua-cam.com/video/P3I7dDpkJps/v-deo.html then your left with the issue most likely being your motherboard. It would need to be replaced.
Please help. My acer aspire 4250 battery is dead, and laptop doesn’t power on when it’s plugged in.but without connecting in laptop the power cord light is on and goes off when I connect to laptop.need ur exper advise.
If it starts going up, that could be a bad thing. Im not sure what computer you have or what the problem with it is, but most laptops dont operate on that high a voltage. Have you tested the charger? Does that same problem exist there or is it just with your jack?
Hello, My PC is not turning on, I have bought a new OEM HP charger, and a new jack and it didn't work ( the light in the jack didn't turn on LIKE YOURS ON THE VID). I have ordered a multimeter to check if the port on the motherboard is working. but what if it is not working? what will the problem be? Can you help me with this, please? Thanks
If your computer does not turn on, have you tried the first video yet? ua-cam.com/video/_MOe71kBPOY/v-deo.html If that video does not help, then I would suggest doing a BIOS Reset; ua-cam.com/video/VO5BhbiItCM/v-deo.html After that, I would then test the charger and power jack. If those check out ok too, then your looking at needing a Motherboard replacement.
@@PC_Monkey Hi, I have fixed the problem and here is how I have checked by the multimeter, the charger (working), jack (working), the port on the motherboard (working). So next I have checked the MOSFET on the other side of the charging port, and there was a 19.5V of one side of the MOSFET and a 0.8V on the other side. so I have soldered tiny cable between the 2 sides and it worked. maybe you can make a video about it. Thanks a lot, I wouldn't solve it without you.
Hi! My power cord is working but my laptop isn’t charging, no light is coming on to say it’s charging or fully charged and it’s not turning on, what do I do?
Hi, my Lenovo laptop has no power, does not charge, and the little light on the beside the charger port does not even turn on, I was told it was the charger and battery, I bought the charger but was unable to purchase the battery, would the little light at least turn on with the new charger? Because it doesn't. Do I still need the battery or is it the charger port? I have done all the other trouble shoots.
I've done all that, I tested the charger and it was dead, so I bought a new one, still no sign of life, I tested the charger port and it works fine. Is there a way to test the battery? It's a Lenovo L14L2P21 for IdeaPad 330s-15ikb.
@@alexrod1639 If you have already started at step one and then did the BIOS reset, and then came here and tested the charger and power jack and everything checks out, its most likely your motherboard at this point :( It would need to be replaced.
HP pavilion dv6 not powering up, 19 volt supply is coming to the mother board from the the DC jack still the laptop Is not powering up, can u, plz tell what can be the problem.
I have dell inspiron N4050 model. I had problem on dc jack there one cable was disconnected. Now I soldering that one but the problem is when I plugged in the charger pin, laptop power indicator showing green and red light beeping. Now what should i do? Whats the problem? Can you tell me please?
Well, I followed it through, the charger is good - check. the power jack where charger goes into is good - check, but as soon as i plug it in the board, the light at the end of the charge cord goes off. Bad board?? if it is, any good parts place I can buy one. I have a Inspiron 15 7559 2.6ghz.
I had a bad charger continued to use it but it wouldn't charge. The computer would turn off frequently. Kept turning back on. My laptop was on this morning now nothing. Plug in the new charger nothing. Did the static thing nothing. Tested all jacks as you described everything is getting power. BIOS reset nothing. What do I do.
If you performed the first 'Computer Wont Turn On' video, the BIOS Reset video, and now have tested the charger and jack with nothing identifying the issue, then your left with needing a motherboard replacement. Let me know if you would like any assistance with that operation.

@PC_monkey do I need to remove the motherboard to test the port on the motherboard
Thank you! I worked on this for over an hour and watched six different videos. If you had not said something about the voltage and amps, I never would have looked. Then I noticed I was using a dell charger on an HP laptop. And the voltage and amperage were slightly different. I rummaged in a box and found the HP charger and it works!
Glad your all set :) Always here if needed !!
Correction: the amperage on your charger should be higher than what your laptop draws, voltage is the requirement and the current will be modulated (not drawn to the max of the charger). Using a charger with max amperage capacity of less than your laptop requires may damage the charger.
Great vid, informative and easy to follow. Do you have any videos on taking the top off ? I have an hp laptop that has the exact issue with a bad port. Did all the other tests up to that, and 100% positive it's a bad port.
So your looking for a tutorial on accessing the motherboard in you HP?
Cool videos, thank you! I have two type c charger ports in my chromebook and ligths didn't work on both, i assume it's not likely both of them broke down?
No, not likely.
1. For a computer that does not turn on, try this video first; ua-cam.com/video/HHwzA37r4e8/v-deo.html. Let me know how that goes :)
2. Also, did anything happen before this issue appeared? Liquid spill, overheating, Windows update, etc?
Your videos are awesome, thanks. Very clear and extremely helpful. I've got no charging on an Asus R556LA. My cord works (putting out 19v), and I've replaced the battery, which will turn the unit on, but it's still not charging. I'm suspecting the power jack, so I've ordered a new one - any tips/instructions on how to replace? Is it soldered into the board, or will just snap in? Any help much appreciated. Thanks.
It depends on the computer. I dont have one of those in my shop and cant find a motherboard access video online :( So it would depend on what you see when you open it up. Most computers however, will have it soldered on
Elaboration and question -> I think the power jack or power supply has a problem on the hand me down laptop I just received that didn't turn back on (battery is a goner, so I'm depending on direct wall connection).
Already separated from the motherboard, a multimeter applied to the -power jack connector- while the P.Supply is plugged into the wall will show 19.5V, but moving the cord/jack around where it's plugged in on the PowerSupply side causes huge fluctuations. Stop moving cord, stabilizes IF in certain positions. I tried attaching jack port back into motherboard so I could see if the motherboard side is receiving the 19.5V (when stable), but my motherboard does not have an end like yours to apply power/ground probes to - it is mounted vertically, rather than horizontally to the motherboard (your example being horizontally mounted/attached), and the other end of the motherboard at that location HAS 4 soldering points representing the 4 (2 black, 2 red) positions of the jack port on the other side. When I try to place my probes on these soldering points, I get an extremely low voltage reading that doesn't change. I'm not sure if I'm supposed to see full voltage at these soldering points or not.
What do you think? (I ordered a new jack port and power supply plug on Amazon thinking I could just return them if it doesn't correct things)
To clarify something else too - the power supply jack doesn't fluctuate on its own (while not connected to removed jack port) but it's very hard for the red probe to find a spot where it gets voltage.. hence why I decided to remove the jack port and test them together).. because it seemed really difficult to get the voltage, and there is a missing chunk of plastic on the jack end, but I still wasn't sure if it was bad or not.
Thank you! This video really helped me to diagnose a dead Packard Bell with that same kind of DC Jack Cable. Cheers from Chile!

I followed instructions on video (very helpful) have completed processes for eliminating static, have done driver and BIOS updates and still me Dell 5559 inspiron will not recognize the charger and the battery won't charge. Unfortunately I have drained all my batteries so I can't continue to do other diagnostics. Is it possible that I need to replace the mother board? Concerned about buying a new one if there are other causes for this problem. Any guidance is greatly, greatly appreciated!
Great video!! I have a question.
My laptop discharge very quickly when i unplug the jack.
In this case the problem is the jack or the battery?
Thank you! You're amazing!
The battery drains very quickly when the power adapter is unplugged? How fast from 100% would you say until its dead?
@@PC_Monkey yes.
When I unplug the Jack after 3/4h the battery is almost 0

Very good. Very informative. Ironically the laptop your performing on is the EXACT one i have. I followed your steps... power adapter good/ getting power from MB/. Maybe I’ll go to the other video -bios reset? Not sure. Voltage is spot on with your readings too... this was the first time i used this laptop in 3 years. Any suggestions would be greatly appreciate. Keep up the good work. Thx bud!
Is your laptop not turning on at all? Whats the issue with it?
PC Monkey yeah sir! Correct. I have an older Hp 15 - F9H96UA.
But... upon further investigation AND more importantly looking through all your vids... i noticed the power supply(button) on the back has a wire strip break off (solder)... sucks cuz i dont have another replacement part or strip. After putting in Bio battery (from ur video). You said something at the end which i hope everyone takes heed.... you said, “ make sure all your connections are good”... great advice bro!

Hi first let me congratulate you, for your fantastic videos, thanks to them, i already make some advances in my pc diagnostic. I have an hp Envy 17-s143cl laptop. This laptop do not start, whith the battery or with the power charger cable. When i connect the power charger cable, the little light at the power jack connector side, do not bright. And when i press the power buttom, no light, no fan, no sound neither.
Now if i already checked that the the charger, the power jack and the power jack port have 19.4 volts, what need to be my next step? Is the mother board failing? Please, do you have another video, that i can follow? Thank you, very much for your help!

This is every helpful. Would it be possible for you to create another tutorial on how to test the Lenovo type-c charger (65W)?
Just watched the Video's very good. Not being a Technician, if I buy the Connector part which is not expensive, can install myself. Does it entail just unplugged the old and in plugging the new. HP Diagnostics said the connector / adaptor passed the test???. Its either that part or I'm stumped its still reading 4%. Now I know where the hidden screws are to remove the cover I will suck all the dust out and pull out the connector device and then plug back in???
Yes, usually the power jack is not a very expensive part. If your power jack is on its own board, it would be a simple matter of removing the board and replacing it. However, many power jacks are now a part of the motherboard and not on their own board. In that case, it would be a matter of replacing the motherboard or un-soldering the power jack and soldering on a new one. I dont understand the last question.
Hi, I have similar problem and came across your video, it was really helpful. But i have a doubt, hope you can help me.
From last few months my laptop don't turn on if i leave all night plugged in or also if i forgot to pull out the charger after shutting down.. next time it wont turn on..
this keeps happening i assumed its static and followed your previous to remove static build up..
but this time it didn't work out .. so i bought a multimeter, new power jack and a new button switch .. thinking these could b the problem
first i checked the power supply in charger and power jack with multimeter both gave me 19.5V ..perfectly fine
But when i about to check the power passes to the motherboard, i thought to match black with black and red with red.. but it gave a spark.. when u say put red on metal bracket..what does it mean ? and I haven't separated the motherboard it is still in place. do u recommend to remove separately and check it ? .. and can u tell me at what plave should i place multimeter red port .. and what is metal bracket ??
You dont have to remove the motherboard if you can easily access the power jack without needing to do so. Every power jack is different. They are not all the same so I cant tell you exactly how to test it. What is the model number of your laptop?
That's easy to repair my laptop through ur way thanks🤗

Assuming you've checked the charger and everything else. Using your voltage meter what should the reading be in the battery port. I think i have the same model in your video and I have 8 prongs on the back of the laptop. 2 Neg (bigger) 6 Pos(?). I get readings from all 6 Pos except one no matter which Neg prong I touch to.
I’ve binged watched a bunch of your videos I love how clearly they explain everything. I’m only stuck on one issue. My charging port doesn’t look like it can disconnect it looks like it’s soldered to the motherboard. How do I check with the multimeter if it is receiving power? I used the tutorial to check the charger and the charger is good!
The powerjack should submit power to the motherboard through one main pin. Towards the middle of the rear of the port. That is where the charge should be read. You can put the black connector on the outside of the metal. That would be ground. Does that make sense?
PC Monkey yes it does I see the pin. The black one on the pin and the red one anywhere? Or just the black?
@@tigara1219 Try both but the Red should go onto the metal component you believe to be the power or the live power transfer pin. The Black should just go on a ground. Does that make sense?
PC Monkey wow you are excellent at explaining things I am a total noob and I understood that 🤣 Cable has power. Charging port has power. Still won’t turn on 🤦🏽♀️ What the actual heck
@@tigara1219 And you have already tried the first video testing the Battery, Charger, and trying a Static Discharge? And you tried the second video trying a BIOS Reset? If the Charger and Jack check out here then your left with needing a Motherboard replacement at this point :( That could be fun :) And depending on your computer, it may be cheaper than you may think. Need help locating a Motherboard?
very helpful. my dell laptop e6530 charging jack has 2 red wires, 2 black wires and a blue. one set of black and red gives me correct voltage, but the other sets are off. are any combination of red and black supposed to give me the 19 volts?? thanks.
i have HP brobook 650 G1 some water fall in the Specker and the power Butten after a 3 days its work but when i but the charger and leave it in the laptop its not work . what you think its Borken ?
Thanks! That's for laptops with a detachable power connector. But when is onboard... any ideas? Tired of looking for the schematics of my Samsung np700
You can still test a power jack thats soldered on to the motherboard. You just have to locate the power transfer pins.

I think a surge of power from one of the batteries or from not draining other components when replacing a screen on a Dell Inspiron 1500 fried something and now it won't turn on at all. Went through both this video and previously went through the "drain the power for 60 seconds and test battery and power adapter video" and also the unplugging the BIOS battery for awhile, and I can confirm correct power is getting TO the motherboard, but that's as far as I can get. If power gets to the motherboard, what's the next thing to check? (Do I have to test anything regarding pushing the power button on to know where the power goes next?

What are the main cause of the power jack and port not working ?
that is a really nice video👍
Sometimes components just break. Physical damage from falls, hits, etc. But sometimes incorrect power can hurt these components as well.
Did you get a voltage reading when you tested the white wires with + red wire? My laptop power jack has a single white wire which does not register voltage with + wire. The black and red wires are fine showing 19V. My laptop will not turn on with good AC power adapter (tests at 19V).
The white usually will not show a charge. The red should. For a computer that will not turn on, have you tried the steps seen here? ua-cam.com/video/P3I7dDpkJps/v-deo.html.
@@PC_Monkey Thanks so much for replying! Yes, the red is + and black is -. When, with power connected, I touch both with the meter leads, I get 19V. When I touch the red and the white I get no voltage. I assumed white functioned as ground and meter should register voltage with the red wire. But it doesn't.
My laptop does turn on and functions properly on battery. It does not turn on with battery disconnected and AC power adapter plugged in. When the computer is on, the power adapter will not charge the battery. The power adapter is good--supplies 19V. The weird part is sometimes the battery will charge up but only if the laptop is completely turned off! I did try resetting the bios by removing the CMOS battery as you suggested in the other video, but no luck. Something funky is going on and I really like my EVGA SC17 laptop!

Yes, you can test into a motherboard and hopefully find the component that is faulty. That would then be replaced. But no, I dont have any videos on that level repair. If my motherboards need to be repaired to that extent, I find it faster and easier to replace the board. Sry :(

Question I have a mini desktop that when I plug in the ac adapter the power light on the ac brick turns off. Motherboard power port has 4 leads and then five pins that go to the motherboard . All pins register continuity is that normal?
You said desktop but also said ac adapter. Do you have a desktop computer or a laptop? Most desktops dont use an ac adapter.
I have disassembled a MIIX 510 which doesn't turn on or charge. The power button will spin the fan for 1 second only.The charger gives correct 20V, tested with a DMM.
However when I plug in the charger, I always see a super tiny blue spark - this can't possibly be normal can it? You wouldn't notice it briefly sparks unless you had it disassembled, as I have.

2. Yes, if the Power Jack is loose like that, most likely it needs to be replaced. You can install a new Power Jack, replace the motherboard that its a part of, or hire someone to do it as your best bets.
Your videos are awesome, thanks for the great content of your channel. About this video, I have an issue that's driving me crazy and I would really apreciate if you help me on giving me some directions. It's a Dell Inspiron 15R SE 7520. The charger wasn't charging the battery and the laptop won't turn on with the charger plugged in w/o battery. It was working only with battery and no charger. I did the 1 minute power on w/o battery nor charger to drain the static electricity after watching one of your videos (thank you again for the great content) and the problem was solved. I had the laptop being charged and working with the charger plugged in with or w/o battery, all perfect. But today, 2 days after fully working, it's happening again. And worse: the 1 minute static dischage procecure doesn't help anymore. I've checked the charger with multimeter and it's ok. I even tried another charger (same specs), no success at all. Right now the laptop works (perfectly) with the battery but the charger does not affect it at all. After watching this video, I've tested the power jack and there's something confusing me: the charger's output is 19.5V / 4.62A and those 19.5V are shown in my multimeter display when I test the charger plug. But when I connect the charger to the power jack, as you show in your video, the multimeter shows only 18.5V maximum. Could this be the problem? Sorry if I bother you with this, but I'm about to get crazy. Thanks in advance!
It could be the issue. Hard to say. Does the battery charge when the computer is off and just wont charge when its on?
@@PC_Monkey Thanks for the answer. No, the charger does not charge the battery even with the laptop off, I've just tested it (30 minutes off with charger plugged in). Also, when I enter the diagnostics mode (pressing F12 and selecting it), it says "Warning: Charger is not detected...". I've also disassembled it, cleaned the boards, changed thermal paste, etc., the problem persists.
@@Zimerer Its saying the charger is not connected to Id like to assume its the charger. Is the charger generic or brand name Dell? If generic, replace with a brand name. Dell is really annoying about that. If its a brand name already and you tested to make sure its working, I am starting to think perhaps motherboard issues at that point :(
@@PC_Monkey The charger is brand name Dell, the one that came along with the laptop from Dell. Thank you very much for your kindness and all the help. God bless you!
@@Zimerer Good luck :)
Hey im runnin into an issue with my acer aspire 5. The battery is not chargin, i took it out, it opens with the ac in but when the cpu goes on higher % it just shuts down. Idk if it can be the ac or the power plug. The ac has 19v output 🤷♂️ could the plug be the reason. Before all these my baterry kept disconecting the ac from chargin till it did not charge it at all now.
Hello and thanks for the video.
I would like to ask if the bad charging port had its led displaying white while you're testing it or does the led on the charging port only show when it's connected to the motherboard?
The power jack LED should light up when the power adapter is plugged into it. No it should not display when being tested as far as I know
You are awesome. This worked for me
Great to hear !! Always here to help :):)
Very helpful. Good tip matching the power supply symbol with the multi meter. When I plug my laptop it starts up for a few seconds and stops. Occasionally I see the BIOS screen for a second before shutting down. I've tested my power supply and the connector on the mobo, it's soldered to the board. I've also removed all components, HDD, CPU, RAM, WiFi. I've left the display connected & keyboard. I removed the BIOS battery overnight. Also checked for a loose screw that may be causing a short. Any suggestion?
1. Are you able to find any recovery or restore options in BIOS?
2. Assuming you have an HP computer, can you try the steps seen here? ua-cam.com/video/_qF-oqPrn7M/v-deo.html
@@PC_Monkey I can't get to the BIOS, I only see the BIOS for a second before it shuts down. PC powers on for 2 or 3 seconds and the shuts down. Not a boot loop problem, also not a HP, it's a Samsung. Tried instructions here ua-cam.com/video/P3I7dDpkJps/v-deo.html Thank you for you help
@@rfausey You tried the manual BIOS reset as seen in that video? Also, if you remove the battery and only turn the computer on with the power adapter, does the computer still turn off?
I followed all these tips. Everything works only thing that doesn't work is the power jack does not light up but I am getting power
For a computer that does not turn on, try this video first; ua-cam.com/video/kOBY4k2Mn_k/v-deo.html. Let me know how that goes :)
@@PC_Monkey I did watch a different view that did explain this process . But still not getting anything after doing some cleaning around and just make sure all my ports are good everything from the adapter to the power jack to even the connector on the motherboard it is receiving power but the power jack is not lighting up with the charging emblem and the power button on the motherboard in is not responding to when I push it Even with the battery in it or attached
I plugged in a wrong charger with 20 Volts over the charger I was supposed to use. Laptop was still working but then wouldn't charge anymore. Would those symptoms be a sign of a bad battery, ports or motherboard, or too difficult to tell without doing these tests? Any help would be much apprecaited
Its possible the battery is damaged. Your computer is turning on and working fine otherwise? If so, can you try the steps seen here? ua-cam.com/video/arZpfqcVoUs/v-deo.html
@@PC_Monkey Awesome, I'll try that, thank you, much appreciated
@@jordandevereux1300 Good luck !! Let me know how it goes :)
In the end I took it to a repair shop, I believe a couple capicitators had blown on the motherboard, so those were changed out and it's working again. Your videos came in handy though self diagnosing so atleast I had some idea of what the problem was. Thank you so much again
Thank you for the video.
My laptop fell on its side while plugged into the charger, which caused the charging port to sink into the laptop, I tried pulling it out with a metal clip and it sparked, yet still turned on, cause the battery had some charge in it. After battery totally died and wouldn't charge I opened it up and tried to replace the charging cable connected to the motherboard, and that also sparked when the screw driver I was using touched the top of it. I don't have the tool to test if there's power like you're doing, but do you think the motherboard is gone now after 2 sparks? The new charging cable isn't supplying any power either.
Thanks.
Unfortunately, yes after two sparks the motherboard may be damaged. However, to be sure you can start troubleshooting a laptop that wont turn on as seen here;
ua-cam.com/video/_MOe71kBPOY/v-deo.html. After that, if those steps dont work, move on to the BIOS Reset as seen here; ua-cam.com/video/VO5BhbiItCM/v-deo.html
@@PC_Monkey thank you very very much for the prompt reply.
I tried the CMOS battery reset, and the static discharge displayed in the video you just linked with no luck.
Also, I don't have a multimeter, but I have an electricity tester, this one:
www.neobits.com/greenlee_emerson_dvc_6_grt_continuity_voltage_p13326331.html?atc=gbp&gclid=CjwKCAjw5Ij2BRBdEiwA0Frc9eyY2f7QJ4VsHasc_iQ2qyGex46DxzRc_lI4G471-6wl7ZUqdN6lPRoCsGIQAvD_BwE
It doesn't test for as low as 20V, but it did produce a sound, so there's a current, just not sure if it's the right voltage. Tested charger, charging cable, and charging module on the motherboard. So there's current, but it still won't turn on nor charge the battery. Any ideas are really appreciated! Thanks again!
@@marwanak10 If the Adapter and Jack test ok, then your left with needing a motherboard replacement :(
Great videos , I'm at this point , I know my battery needs replacing , but prior to it just being a Solid on Orange light on a old Asus X502C , it goes out when I press the power key. Did the Bios reset and put a new CMOS battery in too , tested the charger 19.47 v , all ok , battery ,one of those horrid built in ones , but it stil gave me 1 hour charge which I'd have gone ahead and ordered be it not firstly finding your tuition vidd ,because I've always gone from a article that it does ,esp gaming Laptops ,them good to work off DC alone , so now I'm at a point where I've yet to do a voltage test to the Laptops power port ,and take the mobo out again ,if it's not that it's gotta be comment failure , my issues all started when I was testing a monitor ,as soon as I plugged the HDMI port from the UN powered monitor to the Asus socket it never came back on again, it did for sometime Blink orange but then it's constant orange , so you talking about ,"Static ,that's got me thinking "! The monitor could have been unstable and mmmmm, just thought , if that's blown , and it's wrongly fused prior then it could have Cost me the use of a laptop worth a few quid , but you feel after a while confident and never let you down , gotta say too,Asus , Lenovo,HP, etc , all have this horrible built on board RAM,internal batteries , it's like the days of repair to them ,they don't want them to be repaired now ! But thanks for a great step by step

hey man im having issues with my laptop because it wont show any signs of life my charger is good but when i test the voltage of the power jack i get 5v other than 19v, but my battery charges it goes max to like 2v but when i unplug the charger, i can see on my multimeter that the voltage is going down slowly. I dont know if the battery is bad or i have an electric leak but there is electricity going form the power jack to the battery, and i dont know if it has to do with the problem but there is no hard drive.i have tried a bios update and tested the little battery for the bios and got like 3v. i would really appreciate if you could answer my comment thanks!
For a computer that does not turn on, try this video first; ua-cam.com/video/P3I7dDpkJps/v-deo.html. Have you tried those steps yet?
If the power jack is reading just 5V then that may be the issue if none of those other steps help. You may need to replace the power jack if its easy to do so. If not and if its part of the motherboard, you would need to replace that :(
@@PC_Monkey alright thank you very much
Hello, my laptop suddenly died while I was using it, no charge lights after less than a second I plugged in the charger. It just suddenly powered off. Also I heard a little spark in the power jack area. I already tried plugging it without battery but still no charge light. There is also no burnt smell or any smoke after the spark happened.

Wait how do you get that wire from the power jack to test it?? So confused
My laptop charges with 130 watt adapter. when i plug in the adapter, the battery icon shows charging but I'm pretty damn sure its not. Can this problem also be referred to the faulty power jack or could there be any other issues?
Also, when I initially plug in the adapter and then switch on my laptop, i get the Adapter warning message.
@@sagarmathapandeya4972 It could be either. I would test both the charger and the jack. Also, try the steps in this video. If nothing works, it could be a Motherboard issue :(

Hi, so a/c adapter tested fine, down to dc jack, where again, I don't know what i'm doing.
Mine has 9 wires, from closest to farthest from jack: a single white, then 4 blacks and 4 reds.
Does is matter which black and which red I test. Laptop is a DELL G3 17 3779.
In any case, I somehow managed to get a 19.xx v reading, so this is not turning out as I'd hope.
Tested with original battery and then with brand new battery, a/c adapter tested out ok, as well as dc jack.

Are there any signs of life at all? Lights? Fan, Motherboard, or Hard Drive sounds? Anything seen on the screen?

I have checked by the multimeter, the charger (working), jack (working), the port on the motherboard (working).
So next I have checked the MOSFET on the other side of the charging port, and there was a 19.5V of one side of the MOSFET and a 0.8V on the other side.
so I have soldered tiny cable between the 2 sides and it worked.
maybe you can make a video about it.

Well, I followed it through, the charger is good - check. the power jack where charger goes into is good - check, but as soon as i plug it in the board, the light at the end of the charge cord goes off. Bad board?? if it is, any good parts place I can buy one. I have a Inspiron 15 7559 2.6ghz.
I usually get most of my parts on ebay or amazon. You checked the power jack with the power adapter plugged into it?
I had a bad charger continued to use it but it wouldn't charge. The computer would turn off frequently. Kept turning back on. My laptop was on this morning now nothing. Plug in the new charger nothing. Did the static thing nothing. Tested all jacks as you described everything is getting power. BIOS reset nothing. What do I do.
If you performed the first 'Computer Wont Turn On' video, the BIOS Reset video, and now have tested the charger and jack with nothing identifying the issue, then your left with needing a motherboard replacement. Let me know if you would like any assistance with that operation.
