TLDR; This laptop ended up having multiple shorted MOSFETs on the battery charge circuit. The issue was most definitely heat-related. When you think the repair will be easy because there is a burned chip in plain sight, think again. This repair ended up taking more than 3 hours and shows how some real motherboard repairs go. I would like to know if you like this amount of detail or if you would like me to simplify it? Oh, sorry for the bad audio on this one.

Nice job!! Many people would have stopped at the boot screen, clearly you showed there was still a problem. I am all for the detailed repairs, I want to see the whole process, not the simplified version. This type of thing could come in handy for people in the future. I didn't realize you cant test a MOSFET operation like that, now I Know. Thanks!!
Great job on repair and the vid. I watched 2 of your videos from start to finish i never felt bored at all. The detail is intriguing, I'm no computer technician but I have always thought the circuitry of computers are work of art
This amount of detail is good for us trying to learn! Can't speak for anyone watching for other reasons! This video earned you a Sub!! The explanation as you go is top teacher level!
I really love these long form videos you do. I find them very informative as I don't know much about fixing motherboards and you break things down to a simpler level very well. 🙃
Thanks. These videos have been kind of an experiment to see if anyone will find them interesting. And since the community has responded well to them, I have much more coming. Thanks for your support!
I have this exact laptop. This just reminded me how much I need to replace my old thermal paste and pads and do a thorough cleaning. Heat is the enemy of All electronics. Thank you so much for this awesome video!! I also wanted to ask what is your opinion about underclocking your laptop in order to extend its life. With these laptops you'll only lose about 5-10 frames in games. So it's not a big deal. Do you think it's worth it?
Yes, undervolting is an excellent idea. I did it in my new gaming PC. You won't even necessarily lose frames. In some cases you gain. Now, granted, my gaming PC isn't a laptop, so it doesn't have the thermal limitations, but undervolting actually made it run faster. It unlocked thermal overhead and about 300mhz of extra boost clock, while still running cooler overall and at lower wattage. Always undervolt, especially if you're using fast, new hardware.
Be careful taking it apart. You will have to remove the entire motherboard to change the thermal paste. Just take your time. YES! These laptops are already limited in airflow, so doing anything you can to keep the heat on will extend the life of the laptop.
It can be rewarding to find the solution, but there are those times when you spend 5 hours and never find the solution and have to give up. This repair ended up with 3 and a half hours of footage, and I saved another laptop. 😏
I wonder what the total cost is for this repair, because you've been at it for a long time, just for me to know, because it is delicate work and huge knowledge...
Great job on the diagnostics repair. They’re not always fun and easy. I most likely would replace the motherboard after the first repeated short just because I don’t have the patience for this anymore. Thanks again for the video.
Thanks! Yes, quitting would be an easier option, but then I wouldn't have figured out the issue. I ended up with more than 3 and a half hours of footage, so I did not make much profit, but I hope people get something out of it.
I feel confident that I'm about to learn a few things that had never occurred to me before. Thank you! I've had very little formal training. About 40 years ago. The rest is experience.
Just goes to show why power issues are such a huge pain when repairing PCs. As complex as these motherboards are, when there is a power issue, be it due to a bad adapter, bad PSU, failed component on the board, whatever, you're lucky if it's only one thing that has been fried. It also shows why so many repair companies don't even bother to hire techs that can do bosrd level repair, since there's so much time involved in troubleshooting specific board level components. It's much simpler just to replace the motherboard outright (assuming parts are available, of course), and certainly involves less labor.
I understand whole lots of things about electricity after this video, thanks you soo much. I always want to fix motherboards but my limited knowledge in electricity prevent me so I just ended up swapping
I like solving the mystery, but there is not much money to be made because not all motherboards are repairable. It is easier and more profitable to replace the motherboard.
Still working on the audio. I have an expensive mic, but the main issue is that I am trying to balance noise suppression and voice audio quality. My soldering equipment is very loud.
People should be sending their broken laptops to UA-camr's like you and not to generic Co's that make them. And...... I like how you teach the viewer as you go along, as a result I am subbing. What do you think caused the laptop to have this problem ?
One MOSFETs shorted and caused a chain reaction. The MOSFETs that failed most likely failed due to heat. This type of failure affects all manufacturers, even Apple. There is really no way to prevent it from happening.
Be very careful. This laptop will need to be completely taken apart and the motherboard removed to change the thermal paste. I cannot tell you how many laptops have been sent in for repair after someone "tried" to change the thermal paste and broke something, and then the laptop no longer would turn on. We can do the service for $129. Just keep that in mind.
I'm pretty impressed at your troubleshooting skills. Particularly without the use of a schematic ("crutch" as a fellow tech used to refer to them). I learned to read the circuit boards while working on car audio equipment during the 80s. Things have changed a lot. Circuits continued to get smaller, eyesight got poorer, and I no longer have the ability to hold SMDs still while hot air soldering. To see you use the knowledge gained from other jobs and applying it to this job reminds me of my maturation as a tech. Well done!
Yep, holding those SMD steady in place while soldering isn't as easy when your age progresses. The old discrete components were a lot easier to work with and troubleshoot.
Yes, it does make it a lot harder, but I found a long time ago that you can end up with schematic dependency and then won't be able to fix anything without a schedule. I have schematics for many of the laptops but rarely pull them up.
Hi nice repair can i give you a tip for removing welting chip try not to desolder it but grind it . Much saver for the board and i prefer to use preheater too.
Well, tip, no, not really. If it is truly welded, then you will have to use max heat and a lot of flux and slowly try to separate it from the board. The chip will often break into pieces, and then you can use your soldering iron and more solder to remove the rest of the chip. It just is a bad situation no matter what, and you do whatever you can. Good luck!
Well, I think that is the lower priority item at the risk of damaging your laptop by taking it completely apart to change the thermal paste. Keeping the fans and heatsinks clean and ensuring proper airflow under the laptop will do more for the laptop. If you wanted a thermal paste changing schedule, I would recommend every 2-3 years. Changing it at this interval will save you a few degrees of temperature.
@dellpartspeople awesome! I do keep the fans cleaned v well and making sure no dust or hair build up a lot (we have a dog and i blow out the vents like several times a week bc dog hair can get everywhere) so thank you!!! I plan to send my laptop in to you guys sometime in the future for ram and ssd upgrade bc you guys are dell experts and I don't know anything about upgrading tech lol
I'm retired now, but I have many certs for other brands. Sadly, not Dell, which is too bad, since I do have a Dell laptop. But they seem as easy to fix as IBM/Lenovo equipment. MOSFETs sure seem to be a common problem in laptops of any brand. Job well done. My only "complaint" (if I can call it that) is that low bass, droning constant beat "music" in the background. For those how use high quality head sets, we will hear that and it is so annoying. It's also unnecessary and does NOT add anything good to the video. Please do consider not adding that droning, low tones, constant beat "music" to your videos. Other than that, excellent work.
Yes, MOSFETs fail a lot because of heat, but I would say I see more ceramic capacitors fail. This type of failure affects all manufacturers, even Apple. As for the sound and music, I am still working out the bugs, trying to balance making sure people can hear my voice but also not be blasted by all the equipment noise. I will make a note of the background music.
@@dellpartspeople just a thought... I suspect that most people who watch your videos are there for the technical experience and the sound of the equipment IS THE MUSIC that we're ok with. LOL But that droning thing is very distracting/annoying when one has a good sound system on this side of the display. LOL Perhaps consider not putting any music. I'll bet that the viewers will actually appreciate that. Just a thought.
nice job even though i dont use laptops its good info im a workstation dell and hp fan i have several in my living room mostly xeon powered with as much ram as i can buy and from 4 core 8 thread to 14 core 28 thread
Thanks. Yeah, it is funny that there is no video out there that really explains and easy way to test MOSFETS. I will probably make a separate video just showing how to do this test.
I made a special power volt/amp meter to test Dell and Alienware laptops with. On one side, you can plug in the Dell charger; on the other, it gives you both sizes of plugs for Dell laptops. It is very useful to see what a laptop is doing, whether it is charging the battery or even turning it on.

That is a little high for a GPU. On Dell/Alienware laptops, the max GPU temp is 80c, and the max CPU temp is 100c, but this is only when it thermal throttles for protection, and realistically, it should never hit these temps, and if it did, it is because of bad airflow.
1:50 to anyone who designs laptops for the love of god just use one size screw for the bottom cover and if you need other weird screw sizes reserve them for internal components XD

@@dellpartspeople But what about the very bassy music, very low volume, with the beat. That's no equipment. If you didn't add that, is it possible that the mic is picking up someone nearby playing the bass beats?
It's actually working as designed. It went "black" because it detected a high current situation and shut itself down so as to not destroy itself or the laptop. It just needs to be reset when it does that. Usually it's just unplugging, waiting a few seconds and plugging back in that reset them. That's how he did it here.

sir, i have one qustion if we want an gaming device, between laptop or desktop which one should we consider. i always worried about laptop burning issues
A desktop will give you a better performance per dollar. A gaming laptop costs more and can't really be upgraded. If you take care of the gaming laptop, it should last 5 to 7 years.
We charge a flat $249 for motherboard repair, and if we do not end up fixing it, then it will cost a $79 diagnostic fee. So, after 3 and a half hours of work, I want the laptop to be repaired because $79 is not worth my time. That is why I don't give up.
@dellpartspeople I dont think its worth it. The trackpad sometimes stops working. the top shell has broken plastic vents. some of the screw posts have snapped off and 2 of the arrow key supports are broken. It also has a issue with the hinge as it can wobble since some of the screw posts are snapped off on the lid. The plastic bit inside the charging post is also broken off so I keep needing to put it back in when it falls out. The charger is also damaged as there is wires exposed on the connector. The bezel around the screen is also snapped on one part and it comes off at the bottom when you shut the lid. It all still works for the most part though.
No because a small amount of voltage (not its working voltage, let alone higher voltage) will show up on thermal camera as a lighter object that's overheating.
No. Low voltage and low current. These MOSFETs are rated for 30-80amps, and sending 1-3amps at less than a volt will not damage it. However, what we do not want to damage is the CPU or GPU, which operate at high current but low voltage, so sending more than 1.5 volts to them can damage them.
We specialize exclusively in Dell and Alienware laptops and have done so for over 20 years. We stock over half a million genuine Dell OEM laptop parts in our warehouse.

So, if you own a Dell or Alienware laptop, we are the place to go for parts and repair services. I hope that answers your question.
@@dellpartspeople Ok I see. I mean I try to avoid buying or having Dell laptops at all costs, because they are complicated to open/repair etc. Its not fair to just say one brand is the best, but overall I enjoy to owning/working with/repairing Asus rather than Dell. But good that you exist. From which country if I may ask?
Oh yeah, I forgot to point that out; good eye. A Dell G-series is the same as an Alienware, except it is made of plastic. It is the poor man's Alienware!
They are not necessarily acting as fuses but rather safeguards that block the unwanted flow of current to sensitive components, and this causes them to get destroyed in the process.
Sadly, One problem, I ask, did you over clock the CPU to get the fastest speeds of it? It overheats and without super air fans, don't work as well as the oil coolant Gaming Desktop the overclock them, but they can handle the extra watts that's the CPU pulling? 1 Cooling pads is a plus! Never overclock CPU in Laptop? Burn out the Laptop.

Another bad thing these Built in battery dead! STOP replace asap Why because this can burn out the AC Charger? I know the Battery are a pain on replacing these new batteries? And a new OEM BIOS Battery too!
I dont get it why both Alienware and Dell Laptops especially gaming ones are always the one who happened to have their motherboards being broken in which no matter how I look at their products I never interested in buying them. Meanwhile other laptops always get their hinge broken, but still usable.
Having watched these repair videos for a few years, it's normally Asus and Acer being half price gaming laptops, Apple after a good few years or because someone dropped liquid on them, and sometimes Dell because they're renowned for heating issues - And actually quite rarely the Alienware line probably due to overclocking. For a couple of hundred I got an 8 year old Gigabyte Aero 14 inch with (i7-7700HQ 2.8 - 3.8 GHz, GTX 1050 Ti, QHD) with NVMe and Dual-Channel upgradable and REMOVABLE RAM running Win 11, and while watching UA-cam the processor runs between 1.5 to 2%, and the cores don't exceed 27 degrees - It's even got USB C and Thunderbolt 3 and has a metal case - Never had any issues.
Because the gaming laptops have components that draw far more power and get far hotter so their components are under greater stress. On the other hand. Being far more expensive, the mechanical components are typically better made.
All gaming laptops have this kind of issue because of heat, but we only repair Dell and Alienware laptops, and that is why it seems that these laptops are always breaking. If you watch videos from NorthridgeFix, he is getting a lot of Asus, MSI, Acer, and other laptops.
@@dellpartspeople Do you think the reason for these laptop breakdowns is because of the silicon lottery, bad manufacturing or is it buyer carelessness ?

Will that power meter work again as normal or u will replace it?
It's actually working as designed. It went "black" because it detected a high current situation and shut itself down so as to not destroy itself or the laptop.
It just needs to be reset when it does that. Usually it's just unplugging, waiting a few seconds and plugging back in that reset them. That's how he did it here.
I made a special power volt/amp meter to test Dell and Alienware laptops with. On one side, you can plug in the Dell charger; on the other, it gives you both sizes of plugs for Dell laptops. It is very useful to see what a laptop is doing, whether it is charging the battery or even turning it on.
sir, i have one qustion
if we want an gaming device, between laptop or desktop which one should we consider.
i always worried about laptop burning issues
A desktop will give you a better performance per dollar. A gaming laptop costs more and can't really be upgraded. If you take care of the gaming laptop, it should last 5 to 7 years.
@dellpartspeople sir can you make a detail video on how to taking care of laptops
2 mosfet + 30. Part.. now the battery short.. plus time.. what do you charge ? when does an old pc lose the value of being repaired. ?
We charge a flat $249 for motherboard repair, and if we do not end up fixing it, then it will cost a $79 diagnostic fee. So, after 3 and a half hours of work, I want the laptop to be repaired because $79 is not worth my time. That is why I don't give up.
satisfying!
Glad you enjoyed it!
I have no patients for that I would have just replaced the mainboard
I got that laptop but mine is so broken and ready to be put to rest
Well, it may be repairable if you want to send it in.
@dellpartspeople I dont think its worth it. The trackpad sometimes stops working. the top shell has broken plastic vents. some of the screw posts have snapped off and 2 of the arrow key supports are broken. It also has a issue with the hinge as it can wobble since some of the screw posts are snapped off on the lid. The plastic bit inside the charging post is also broken off so I keep needing to put it back in when it falls out. The charger is also damaged as there is wires exposed on the connector. The bezel around the screen is also snapped on one part and it comes off at the bottom when you shut the lid.
It all still works for the most part though.
if you inject voltage into board wont ic be damaged ?
No because a small amount of voltage (not its working voltage, let alone higher voltage) will show up on thermal camera as a lighter object that's overheating.
No. Low voltage and low current. These MOSFETs are rated for 30-80amps, and sending 1-3amps at less than a volt will not damage it. However, what we do not want to damage is the CPU or GPU, which operate at high current but low voltage, so sending more than 1.5 volts to them can damage them.
@@dellpartspeople Interesting.
Why do u only work on Dell laptops?
We specialize exclusively in Dell and Alienware laptops and have done so for over 20 years. We stock over half a million genuine Dell OEM laptop parts in our warehouse. We are experts when it comes to Dell and Alienware laptops. We chose to be the best in one brand rather than mediocre in multiple brands. So, if you own a Dell or Alienware laptop, we are the place to go for parts and repair services.
I hope that answers your question.
@@dellpartspeopleit should
@@dellpartspeople Ok I see. I mean I try to avoid buying or having Dell laptops at all costs, because they are complicated to open/repair etc. Its not fair to just say one brand is the best, but overall I enjoy to owning/working with/repairing Asus rather than Dell.
But good that you exist. From which country if I may ask?
We're in the US.
He’s dead, Jim!
What on earth happened to that notebook? Holy cow.
One MOSFETs shorted and caused a chain reaction. The MOSFETs that failed most likely failed due to heat.
That's my laptop model😢
ALIENWARE ICON ON THE BOARD!!!!!?!!
Oh yeah, I forgot to point that out; good eye. A Dell G-series is the same as an Alienware, except it is made of plastic. It is the poor man's Alienware!
@dellpartspeople I have a G15 5520 with the app "Alienware Command Centre" Guess I know why now
16:11 can't hear beep 😢
Yeah I figured that out after the fact because of the noise suppression I had the audio. I will be turning noise suppression off from now on
Dell design uses MOSFETs as fuses. Interesting!
They are not necessarily acting as fuses but rather safeguards that block the unwanted flow of current to sensitive components, and this causes them to get destroyed in the process.
Sadly, One problem, I ask, did you over clock the CPU to get the fastest speeds of it? It overheats and without super air fans, don't work as well as the oil coolant Gaming Desktop the overclock them, but they can handle the extra watts that's the CPU pulling? 1 Cooling pads is a plus! Never overclock CPU in Laptop? Burn out the Laptop.
Not sure...
Because parts people specilizes in dell.
Yes, we specialize exclusively in Dell and Alienware laptops and have done so for over 20 years. We stock over half a million genuine Dell OEM laptop parts in our warehouse.

This fault would give anyone the run around.
Chain reaction failures can be real dogs to troubleshoot.
Yeah, I want to make sure people see a real-world diagnosis, and that is just the way it goes sometimes.
I bet they were running this on a bed with restricted airflow.
I think you nailed it! Overheating is the leading cause of gaming laptop death.
not enough flux
your audio is really low
Still working on the audio. I have an expensive mic, but the main issue is that I am trying to balance noise suppression and voice audio quality. My soldering equipment is very loud.
Eureka! 😊
One day you will wake up with a melted keyboard or palmrest.... and you know why. 😊
regulators are cheap insurance
Nice vid
Another bad thing these Built in battery dead! STOP replace asap Why because this can burn out the AC Charger? I know the Battery are a pain on replacing these new batteries? And a new OEM BIOS Battery too!
Yes, bad batteries can cause these types of issues, and you should always pay a little more for genuine OEM batteries.
why dont they fit actual fuses of some kind? saves popping all those parts
I dont get it why both Alienware and Dell Laptops especially gaming ones are always the one who happened to have their motherboards being broken in which no matter how I look at their products I never interested in buying them. Meanwhile other laptops always get their hinge broken, but still usable.
Having watched these repair videos for a few years, it's normally Asus and Acer being half price gaming laptops, Apple after a good few years or because someone dropped liquid on them, and sometimes Dell because they're renowned for heating issues - And actually quite rarely the Alienware line probably due to overclocking.
For a couple of hundred I got an 8 year old Gigabyte Aero 14 inch with (i7-7700HQ 2.8 - 3.8 GHz, GTX 1050 Ti, QHD) with NVMe and Dual-Channel upgradable and REMOVABLE RAM running Win 11, and while watching UA-cam the processor runs between 1.5 to 2%, and the cores don't exceed 27 degrees - It's even got USB C and Thunderbolt 3 and has a metal case - Never had any issues.
@@billyjames9861 You make some interesting points.
Because the gaming laptops have components that draw far more power and get far hotter so their components are under greater stress. On the other hand. Being far more expensive, the mechanical components are typically better made.
All gaming laptops have this kind of issue because of heat, but we only repair Dell and Alienware laptops, and that is why it seems that these laptops are always breaking. If you watch videos from NorthridgeFix, he is getting a lot of Asus, MSI, Acer, and other laptops.
@@dellpartspeople Do you think the reason for these laptop breakdowns is because of the silicon lottery, bad manufacturing or is it buyer carelessness ?
The arounds of the badly burned mosfet look baked.
A lot of heat is produced when charging the battery.
am at the beginning of the video, my guess is a dead PMIC :D
