Hi,
Has anyone got a board view and schematic for 820 00687. Water poured over laptop and now not switching on. Signs of liquid damage on board that I have attached to this image. The image with the highlighted caps I have found only have a resistance of 9ohm to ground and have found from injecting 1v voltage they have something to do with the processor. When I say this ,I have used freeze spray and it started to melt away from the processor, nothing else.
Thanks

Liquid on CPU power supply; it is probably trash now.
Why did you inject voltage there?
9ohms on CPU rails could be normal value...

I injected voltage there as that is where I found the short. 9ohms normal, so fine. If it is trash though, that is may answer. Looking for other things to try to learn more from it.

Why do you think is short?
I just told that could be normal value; if is on the CPU core coils.
You must interpret the values!
