Re: HP Pavilion ZD 8000 won't turn on

First of all, thanks for the schematic! I noticed that the rev 2 version I had downloaded didn't exactly match my board, but your 2B version does!!!
I see your question is two month old without a reply. Did you manage to fix the board yet?

Did you check if ACIN (pin11 of the MAX) is > 2.1V? This is where it detects the 19V. When it does, ACOK (pin12) will go low, activating the ACOK circuit that turns on PQ15 & PQ16.

I have to reflow the GPU for the second time :-( because it has worked itself loose...
