Finally found another good troubleshooting channel. Awesome!!

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.

10 years ago laptops came with socket so gpu and cpu could be change with out problems, like the video

Great video once again thx 👍

Love you man Great job 👍

Nice my bro, never give up better days are coming

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.

Thank you. Nice video.

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?

Excellent explain sir.

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 ?

Great explain sir👍👍👍👍

Nice INFO iam still in the learning mode still need to learn alot

Do u have a link for schematic sir? The link u posted on gdrive is no longer working. Thank u

I've got an Asus gaming laptop I was fixing the fan then the whole laptop turned off what should I do?

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

Bravo 👍

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 ...

Thnks broo...✌✌

Learnt a lot must say

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

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 ... ;)

Not good. Somtimes cpu having 2,5 ohm on Gt Vcc and is Bad 😢. Bad cpu on the Vcc Gt section . 😊

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 .?

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.

why not inject voltage and check with a thermal camera where the short is coming from?

Is it possible to Convert this laptop to UMA only and disable GPU section Completely ? So that this laptop can Run only with 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

What about the ram for the gpu .. there are capacitors there . Maybe the shorted

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

The board will still work like that. It will run off the intel graphics. Done it many times

What about RTX GPUs, they have very low resitance?!

You have offline video course?
