wow 3 videos in one day that's a gift from heaven
DR Khaled, are there any others videos today? I can't see them...
@@Mecano.r I don't know what happened but likely he deleted them
loved the suspense, it was like a thriller movie. AWESOME AS ALWAYS!!!
I bet everyone here says "Hello" right when the video starts I caught myself doing that lol
Sorin is the Greatest !!!!!
It’s Tuesday right
no it's wednesday actually
Every time I start a video on this channel, I am greeting him with, Hello ! 😊👍
I also try to guess the day. It's a buzz when I get it right. Love this Man.
Time to upgrade the channel name to: Electronics Repair University.
If you even knew the level of knowledge on University compared to what you see here, you would laugh.
@@GKirChhOff sorry to bother you but is sorins channel on discord not working any more ?
@Braden Ronin 🤣🤣🤡
@@GKirChhOff I don't understand where is more knowledge on this channel or the university???
Amazing as always. I've never seen so much love for for a man whose channel isnt about sugar coating or mushy feeling things. Yet video after video us geeks, nerds and enthusiests keep being amazed and educated while feeling comfortable and not left out of what is actually happening. When he takes a call or goes to find parts in the shop, i feel like im there and am perferctly fine with waiting. Any other channel i would have left. I'd like to think i was his biggest fan but i think we all hold that title. My god and savior, Sorin. Sorry for my spelling.
Dear Sorin, I am watching you from Hungary so we are kind of neighbours, greetings from here. I just want to say thank you for your videos, what I watching a lot and these are awsome. I bought some stuff to repair myself, also built a power supply myself, now learning electronic from books and online.
I just would like to share my first 2 succes. A laptop, no charging or turning on, succesfully diagnosed a faulty dc/dc step up converter, so it is fine now. Second one is a Gopro, water damage and no coming on, cleaning, isolating everithing with self made liquid rosin flux as you tought, I have found a short on battery board, which was succesfully found and treated. No it is turning on :)
THANK YOU!!! And keep on!!
Good job!
Ești foarte tare... Spirit roman... Muncim cu zâmbetul pe buze și radem și glumim... Și rezultatul e uimitor. Și eu sunt tehnician și ma amuz în fiecare zi cu tine pe UA-cam. Bravo
Mr Sorin is my electronics Mentor . I started making small Guitar electronic repairs at home (basic stuff), and now I run a small bussiness . He's not the best electronic tech in the world, but his huge experience and approaching to find the issues, makes you believe that you can also learn do it by yourself and improve what he taught to you. He's a master teacher and deserves a big respect for me. hugs from Portugal !
Hi, Sorin, Hero of the Universe!
Central pin on Dell chargers carry a 1-wire signal that decodes to charger wattage, serial number, etc.
Sadly it´s not just a "high signal" like Hp´s.
Could that be why the machines won't start after being unused for a long time? ie The machine is too dead to read the ID of the charger? Lots of people on the Dell site could not start machines that had stood unused for a ear or so.
I'm so glad you faced this heating problem with the soldering iron you can't imagine. I've been struggling with the same problem and really enjoyed to see how you dealt with it.
My Mentor, sir I just recently picked interest in Computer Repair, and thank God I came across your channel. You're a gift
took me at least 45 min's just to open, my first time with that model. completely focused & without an audience. very modular, nothing like it outside of certain gaming laptops at twice the price.
thanks for the walk-though, wish I had you years ago!
~v~
this last one deserves a big like. very inspired by your passion. i have now a power supply because of you. thank you for everything. elbow shake from portugal. give my best to Diana. our women have to have patiente to us (electronic technicians)
true about the patiente ;D , i put electronic stuff everywhere in the house ;D a nightmare for my wife ;D
@@v1ncend yes. That too. My case is more about the calls I receive all the time to repair something...
The M6800 was the top of the line for DELL
It even has upgradable CPU + GPU
the end was cool burn ;D
Yes I like that too a Burning Motherboard 😁
Well I used the knowledge of diagnosing bad caps on this channel and fixed up a $30 high end Latitude E6430 with NVidia graphics and HD+ display which has a shorted capacitor right after the 2 MOSFETs! $30 for such machine in great shape is a steal!
Hi there,I'm from sourh africa, port elizabeth,great channel,love to learn from you.
This is absolutely the Dell thing ( not charging properly without the genuine charger). It's the way they "protect their produts". The funny part of everything is that they actually do have some 3rd party production called XRT. They are dell approved and these are the only ones (as far as I know) that are working the same way the originals one work. Thank you for the nice video Sorin
and new HP models has a same, but chargers are not is not replaceble among Dell an HP
Greedy companies. Just like apple with there certificate for apple cable chip.
And I’m saying this as a apple user. iPhone and iPad.
This is something that should be prohibited by law to lower waste.
Thanks Sorin.
Still watching your channel.
it's Amazing.
Grate having you back am from Jamaican wish you all the best
I would recommend the Hakko chisel tips (D-xx series) or the flat BC ones. The shape of the bend J-tips is sometimes nice, but it's tiny tip is very bad at bringing the heat to the board. The only way the J tips work for me is by using the thick curve on the back. There are also two J tips...a bit shorter and a longer one. The shorter one is a bit better than the longer, but they're both far away from the performance of the D or BC style tips.
A tip to help with your soldier iron temp you have to have that blue plastic key thing in the front to change temp. I leave mine in all the time. Hakko does this so co workers won’t change temps on other persons station area. I went through the same problem as you until I found this tip out then my iron works great now. Better then my wellar. Hope you get this to help Sorin....thanks for the videos. P.S. I can tell with that tip your stuck on the factory settings. New station once you get the temps up and working right. You will love it then.
THE BEST MAN ON THIS BUSINESS...SORIN!
Love this channel! Best part where I LOL was when there was a flame.... so awesome! Love ya Sorin. Cheers mate
Where I work I was assigned an M6700 for sofware development. I was able to disassemble it a couple of times since it's quite old and beaten up, and it's having few faults. But my impression was the same, such a cool and well made laptop. I went to Dell's website and they had like a "Workstation" category. I bet they were crazy expensive at that time.
Decent all day heatsinking ability, business use. Overheating itself to death in 20mins..every gamer laptop 😄
The ones that came with all the bells and whistles were 5000€+ when new.
Thanks a lot for all the educative repair lessons...... You are my mentor.
When experience is combined with perspicacity and of course good knowledge then the mixture is called Sorin.
Well done! Have a nice weekend!
Wow that was awesome we saw saw flames and he still solve the problem way to go . Thank you for sharing .
Thanks to you Sorin I started to learn about fixing the motherboards. So far managed to fix one with faulty capacitor and next one I ma working on I asked for help in Discord and I was given precious info straight away. Will see how it goes with replacing that mini chip ha! Thanks a lot for man.
Error mesg on screen after repair is actually a good thing as it means that the CPU and main board is at least trying to work and H/D, ram or something out of place is no good. Amazing when i saw that the layers might have been burnt and even Sorin might struggle with that one as would the manufacture on a multi layer board. Only worry i have with applying too much current is that the tracks and even layers might get burnt and 2-3 amps has to be enough to heat something up and feel it , i keep to around 2 amps unless i need add more. Parts get stressed over time so another cap might start to burn out even when you found shorted cap and then alter another cap and so on. Love this channel, best on the Interweb!!
Happy to see a real laptop here. Not the usual consumer crap that is engineered to be as cheap as possible.
thank you so much Sorin
Its a pity you didn't go further with the broken connector/Inspiron.
I have the same model. One day just popped up can't detect the charger.
Bought a new Dell 45watt charger like the original.
Same error, can't detect the adapter type.
Borrowed a Dell 65 watt charger and still the same error.
Replaced the socket even though all continuity was fine.
Battery will charge if I connect it to a bench psu.
Everything else works just cannot detect the adapter type.
Great channel by the way. Keep up the good work.
You are helping to keep me sane in lockdown. Thanks
Hey Mr, Sorin...nice to see you again.
"maybe we can see some smoke somewhere.." love it.
You don't have to rename the channel, you stay number 1. great and thanks!
New to the channel. Thankking for making the concepts easy to understand... Very Practical for a hobbyist like me. Keep up the good work and can't wait for your uploads.
I really like the Precision line over the consumer rubbish especially the older 17inch models as one can do so much upgrades wise and they'll just last.
That one is a 4th gen Core. I have a pair of M6700s from a former project and a couple of M6500s. Beautiful systems.
Hello, Mr. Sorin. Dell laptops require a Dell adapter, otherwise it powers on but doesn't charge the battery. Theres a chip inside the dell ac adapters that comunicate with the motherboard using the center pin, telling the mobo that the adapter is authentic. If you enter the BIOS it must recognize the adapter by indicating its power (65W, 90W, 130W), etc. Maybe that's the problem. The charger you are using doesn't pass that information to the motherboard. You can google for more information.
The way that works . its call a ! wire circuit. That 3.3 volts goes from the mother board back threw the charger wire to the I.D chip in the charger if the connection to the part of the port is bad it can read on the motherboard side but not charger side. It could also be the super IO extender chip it used in dells.
1:24:10 "speak with me i am friendly" but on another side kicking it with 5amps and evil smile :D hahahhahahhah
IDEMO SORINEEE 🇷🇸
IDEMOOO IDEMOOO🇷🇸❤️
Idemoooooo najzad bas mi nedostajao!!!!
@@ElectronicRepair.Serbia2023 Mene on bas smiri.
I saw a lot of Dell with this error... usually after a power supply replacement... there are some Indian videos about bypassing the ac control check.
Whew, I was on the edge of my seat. Rename episode to "Beat the clock"!
Good Job. i have repairing with jumper method too.
Hi. It's fascinating watching the way you figure things out and find ways to recover from what look like impossible disasters! I got a pleasant surprise when you picked up the Dell M6800, as I have the M4700, which looks the same but without the fingerprint sensor. I agree that these are proper laptops, and I love my own, so it was good to see you figure out how to get the back off. :) I bet somebody bent the case, when they couldn't work out that it slides off! I just watched another video where you say you try to read comments on the old videos, so I came back to ask if ou videoed the next day of finishing the repair? My problem is that something corrupted the startup of my Windows 7 device so it could not find the Windows start file, and I did not have time to find out how to fi it, so I left the machine unused for a couple of years. Then, when I had time to look at it again, it would not start. The fans come on, but then it turns off without going into the startup sequence. I thought the BIoS battery might be dead, so I tried to change it. Then I discovered just how 'Precision' they made these things! The fitted battery has welded on leads, and there is almost nowhere where a normal battery holder can be fitted! Even if you try to run a battery wire over the back of the cooling ducts, the back will not slide back on! I had no welder and could not solder to a battery case, so I ended up drilling through the side of the depression for the battery, so that I could run wires to a battery holder on the other side of the case. It was a tight fit getting the back on even then, and the case metal is surprisingly hard to ordinary drills! Very well made! Sadly, it still would not start after putting in the new battery, so I was pleased when I saw you working on the similar machine. You had to put it aside to finish later though, so I never saw how you managed to restart it. :/ Is there another video with the rest of the repair, or more on similar 'Precision' machines? I notice that on the Dell site, a lot of people had had the same problem of the machine refusing to start after being unused some time, and nobody had found a reliable way to fix it. Maybe I will get more ideas from your other ingenious repairs! Thank you for all the entertaining and educational lessons. They give me plenty of ideas. (y)
3 caps in a row? That's world record. They were near the part of the chassis that got bent, maybe were damaged in the accident.
well after a raped connector like that only God know what mess happened
Happy birthday dear Sorin !
Thank you!
Oh god, can't believe the lighter fluid actually caught fire haha! Gotta keep the repairs exciting. Great work as always!
I think it's gas as in petrol but I could be wrong
1:26:22 good old times. Removing the entire GPU and replacing it instead of throwing the laptop in the bin.
FANTASTICCCCCC VIDEOOOOOO AGAINNNNNNNNNNNNN...........looking forward to the next episode Saluteeeee
You are a legend! Love the videos!
Had to power a thinkpad with the bench power supply the other day and found out you can trick the psu sensor by using a 180 ohm resistor from middle pin to ground. Unfortunately I'm pretty sure it doesnt work on dell cause they use a chip inside the psu instead of a resistor. Nice video Sorin you're the best! Cheers from Brazil
Actually no this is not always good idea. On Certain HP laptop you will have slow laptop and there may not be protections against if you make mistakes. BUT you can make emulator for that and its same chip as Apple used on Magsafe.. i am using +200W HP charger as DIY Apple "80W" MagSafe charger with own emulator as for ID on my macbook pro.. can fake same way to be any Dell charger as well... :)
Precision is Dell's professional mobile workstation line. Basically desktop replacement machines with dedicated Nvidia Quadro graphics and powerful CPUs.
Very, very usefull video and lesson as always. i think that dell bios has an information about a battery without to upload a windows. Also, think that this model has a possability to set "charger biheviour" to charge without the "3-rd signal" -ID of charger.
In Dell Power Supply used 1Wire communications.
Pin ID mostly is 0,2v 0,3 v after pluging in laptop is 3,3V .
The people are wild as hell just sending stuff there lol
that last dell is nice it is very similar to my dell precision 7510, solid build I7 with 32 g of ram
Hey man I recently got water damage on one of my MacBook Pros & I really need it for school. I have 2 MacBooks, 1 with water damage & 1 with a broken screen. If you could reply to this comment it would mean the world man.
YOU ARE THE BEST!!
Pop? I love your job. But Pop do you accept advice? Because there's a technique that will make you fast how to disassemble a different model of any laptops just by watching here in UA-cam that really helps a lot. Just type in the brand & model of laptop then watch here in UA-cam on how the guys disassemble it and each group of screws attach it with adhesive tape designed to each platform cover of laptop so it will be to make life easier, so when you assemble it back together, you know those group sizes of screws belong to that location. If I'm late to mention it, good for you those techniques and you're still impressively fast to troubleshoots issues! But luv your job giving me also good ideas. Thnx for sharing your videos pop. 🙂
936h soldering iron is good and no need to wait for it to get hot. It almost instantly getting hot. I always use it
Great teacher and engineer 👍🤓💯
What happen to the other video, was excited to ses how not to fix a laptop. I am a learner and some of the most value lessons comes from you making mistakes so I dont do them my self.
Also very often I come to an dead end and desperatly starts to try different things without fully understand what it will do. So it is nice to know what I definitely should NOT do.
I get my hands on old dead laptops for practice but I haven't had any success. I think I have found out why they don't work but I cannot locate where the issue is and end up completely ruin them.
@@HenrikHvalpen what do you want him to do ? he can't teach you the basic , take a course or read about basic then come here to learn , this channel for advanced users which if you don't know the basic you will feel blah blah in this channel
I understand a lot of things and also if you haven't noticed he has beginner lessons too where you learn the very basics.
The things I find hard is like when I can measure a shut to ground, but I can't seem to locate the exact problem, and when I finally come with the amps I feel allot of components getting warm. Next just to try something I unsolder them to see if the shut to ground disappear. What I find out is, it is some voltage converter chip that splits 19v to 5v and 3.3v. And there is my dead end.
Is the chip suppose to shut to ground when the power button isn't press or is it dead?
Most of the laptops I have practiced on is build very differently than the ones in the videos.
By the way I am starting to take lessons too. But Covid have delayed everything.
@@HenrikHvalpen warm and hot are not same thing a lot of components gets warm, if you have laptop to practice use more amps and put ethanol or zippo flud on area you suspect to see which one will "answer" but be careful in any case with amps
@@corel965 Thank you. I find areas on many laptops where I can measure ground on both sides on the capacitors. When investigating I often found out it is the same rail for either the CPU or GPU. So what I find difficult is whether I found a fault or it is suppose to be like that?
Nice one Sorin, Kudos!
Mr sorin.thanks for all ur video...ittts veryyy helpful
Master Sorin It is a very nice table. Wish you use in health. I missed your videos
The best video ever you made! Like watching triller movie. You are realy the best!
I think you need to calibrate the tip/iron. Real temperature on end of tip is more lower than it shows.
Maybe is just a bad fake of an hakku.
Wow that was an amazing solve
Great job Thanks Sorin
👏 simply amazing. A joy to watch and learn.
Dell laptop needs dell charger - this is where the A/C error is coming from and it won't charge the battery otherwise.
i want to see sorin doing bios firmware programming and editing me/txe regions, it will be a very nice video for everyone 😊
haha that was nice :)
or to see sorin doing chipset or gpu replacement with the changing new solderballs to pb-type one.
(with his favorite approach: "500 degress" on hotair) haha
You are magician!!! 🙌🙌🙌
Most entertaining video lots of fun watching you ... You are the best
Good job
Man, I saw you in many situations, but this was like in... Mission impossible 17 !!!!
He feels bad when the customer send him the connector.
Very nice Job..
So that’s a horror movie 🍿 and right on time done ✅
Another great video, try to use K type tip for the iron it might be enough mass than.
good job
Thank you
very informative video thanks for sharing my teacher
Great video, thank you.
I love the videos and have that dell great machine they are! What is the purpose of the liquid you apply befiore soldering? Great video!
wow changes to the workspace. nice.
Pinche sorin me tube al filo de la silla todo el tiempo.
Good job ! It was so just !!! 🤣🤣🤣
I love your channel, you are my best prof !
Happy to see you
Greetings to you, Engineering
somehow wish you showed putting it back together - for instance - did you need to replace those two caps? If not why not? Thanks for very interesting site...
usually i don't replace a single capacitor, but here we have 3 so i did replace them
is the middle pin not along the lines of the new usb c standard. It may be a power handshake (comms) between psu and computer
3v3 is a common comms voltage. I think it must be waiting for a data handshake like you said. What a pain in the ass though!
I've actually got to fix a shorted board by drilling it exactly on the shorted spot. I've posted the details on the Discord channel ;)
Cheers!
Thank You for this movie
thank you for all the knowledge you teach us, I am very grateful ! I hope to be as good as you at repairs one day, ps in your videos what device are you using to show voltage and current when ever you have a device plugged into a charger?
Thank you as well, do you post what you're using to supply Heat somewhere because I'd like to get one of those devices. I hope you keep on doing it to it!
Wow, right on time! You’re the master of electronics repair!👍🙏😁😘
That was not a simple video. That was a Mission Impossible movie. Pure entertainment.
