Thank you so much for sharing this knowledge, really learned alot from this. Pls keep posting these tutorials video, you're really helping lots of technicians out there.
Yes I am and they’ll never admit, but I know I contribute a lot
Great video once again thx 👍
Love you man Great job 👍
Love you more
Excelente vídeo, muchas gracias.
Finally found another good troubleshooting channel. Awesome!!
Thank you. Nice video.
Have E1 571. Power light after a few seconds. CPU GPU PCH integrated chips heats up but then cycles. Coil feeding 1.8v GPU is about 80 ohm. And same resistance on CPU 1.05v coil. Only thing I can think is internal CPU GPU fault and system power cycles. Resistance between GPU and CPU coils is 150ohm. Should that be more or open line ? For integrated chip ?
Excellent explain sir.
Hello. Mini PC on Intel n100. When turned on, the screen is black, the fan rotates, the radiator heats up, and it consumes about 14W from the outlet (TDP of processor 6); during normal operation, it seems to have consumed about 20W. But even when turned off, it consumes about 10 W and the processor heatsink gets very hot. Processor to be replaced? Can the processor heat up when turned off and consume 10W from the outlet when the processor is alive?
10 years ago laptops came with socket so gpu and cpu could be change with out problems, like the video
I've got an Asus gaming laptop I was fixing the fan then the whole laptop turned off what should I do?
Good video, you can do the same test without removing the coils by using an esr meter. The esr meter will see the coils as high resistance, so if you measure from each side of the coil, you will see where the short to ground is.
I'll try this, tnx
Do u have a link for schematic sir? The link u posted on gdrive is no longer working. Thank u
Great explain sir👍👍👍👍
Nice INFO iam still in the learning mode still need to learn alot
What is meant by the term live boot ok concerning a laptop advertisement?
Nice video thanks. I have a question - the short can still come from the caps that are between the CPU and the coils you removed. You need to remove CAPS too ? I was curious also if cutting some traces is an option to avoid removing so many components ...
ussualy if one of those caps its in short, the short will be maxim low resistance and one of the cap will be warming!
@@glazyrap9244could you please explain it better? I bought your course and I love watching it. Thank you. One of the best professors.
Thnks broo...✌✌
Take care man ♥️🙏🏾
Great engr, thanks for the update,pls can u give a link to download the laptop repair book ocr part 2,I really need it
No worries I’ll upload the links
@@jbvtechnologies Thanks very much big brother
Bravo 👍
Some gpu resistance to ground is less than .1 ohm, especially more recent models, separating the coils can help find mosfet issues though in these cases
About gpu i know, but how about cpu, what is normal ohm for thems?
@@arunasjaspelkis4880 2 ohm and even less in newer. Newer generation are very efficient
depend on the generation @@arunasjaspelkis4880
Learnt a lot must say
You know I love you guys
You can convert that to discreet to uma. The gpu is kill, you can put working the CPU only with Intel graphics card only. ;) not for gaming but for work and surf on net will do it ... ;)
Replace the gpu chip also possible
@@laptopDoctorKZN but you know I don’t have a BGA machine and the cost of the gpu chip cost a lot
Thanks bro, I’m gonna try to convert, do you have information regarding conversation
@@jbvtechnologies some bios will check on the gpu first if it is fail the laptop will give black screen . some other don't check and the laptop just power on right away on the intel hd graphics, it will need bios mod to bypass the discreet gpu check .
I removed the coils from around my clu and upon removal I test close side to cou and get 3 ohms am I right in saying cpu is good as there is no direct short to ground .?
3 ohms sounds reasonable depending on the cpu
I have a hp omen 15 motherboard with i7-7700hq. I measured on cpu vcore side 0,1ohm,with lifted up coils. This is 100% core short to ground, or bad ceramic capacitor?
I injected 0,8V 3A(maximum of power supply), but when i switch on the power supply the voltage was only 0,3v. Nothing hot
shorted cpu . end of the story
At the end what did you found ?
Not good.
Somtimes cpu having 2,5 ohm on Gt Vcc and is Bad 😢.
Bad cpu on the Vcc Gt section .
😊
Is it possible to Convert this laptop to UMA only and disable GPU section Completely ? So that this laptop can Run only with CPU.
Yes.
Thank you for the video! In some cases though it is normal to have very low resistance around GPUcore or Vcore. In these cases, continuity mode will be a false positive. It may still be worth checking the buck converter itself. I've had this several cases when it was the PWM controller or MOSFET faulty despite a "short" on the Vcore side according to the multimeter.
How may we avoid accidentally shorting the CPU/GPU while measuring? I mean the meter does supply a voltage to measure? . Also this mobo looks like an Alienware, is it common for the GPU or CPU to die on these?
@@farmdve the voltage from the multimeter is very low. Typically less than a volt. This isn't enough to short the silicon components out since they typically operate using anywhere from 0.5v to 1.2v
why not inject voltage and check with a thermal camera where the short is coming from?
Some people don’t have thermal cameras, I don’t use a thermal camera myself, I don’t see a reason , so I’m trying to accommodate everyone…Common sense should prevail
no need it is a direct short from the gpu . confirmed after removing coils . no need to dig deep while the fault is pretty obvious
What about the ram for the gpu .. there are capacitors there . Maybe the shorted
The short is coming from the GPU directly, I get where you are going, but that not the case
The board will still work like that. It will run off the intel graphics. Done it many times
Board is Dell Alienware laptop 15 R4, 99.9% Mosfet always fails and make CPU or gpu blow up (destroyed by overvoltage) by design when you change the old battery with new 100% charged voltage. Designed Deprecation
What about RTX GPUs, they have very low resitance?!
You have offline video course?
