Re: hp 17 ak015 ng
Thank you very much! What utility did you unpack? I also downloaded the f.14 bios from the hp site but I couldn't unpack it.

Re: Acer predator g9 591 791
I found the bug. The NVVDD is very low because it is only 3 ohms ahead of the ground. The U8700 does not turn on and provide information on the PGOOD bus. U7000 is dead. Thanks for all the help, the repair is over.Leave a comment:

Re: Acer predator g9 591 791
Boardview is a great help, but without schematic it is difficult to find a bug because I don't see resistance values. Info: "vx r0402 small" all resistors. Maybe the drawing is just that? (Or am I not using the program correctly?)
Help me please, thank youLeave a comment:

Re: Acer predator g9 591 791
First of all, thank you for your help. The motherboard did nothing.19v after the second fet was shorted. U8200 (NB685GQ) complete short circuit!
I replaced the ic, 1.0v came out on the coil. I closed the pads but the motherboard did not start. Update the EC bios with IT8587E and "HALLELUJA" enabled on the motherboard. But there is no picture and it always restarts. I have done more measurements and it is off with 1.0v on the ic output. Ic is on. This is not normal. I replaced the PCH, same. I replaced IT, same. Now I need to find out...Leave a comment:

Hi! P5NCN/P7NCN Rev. 2.0
I replaced PCH and IT but no change. 3.3v 5v ok, no shortcut anywhere. RTC is in it. I give it 19v and it starts automatically and will restart. After 10 seconds the fan rises to 100%. Holding down the power button will turn off. I unplug the adapter, then plug it back in and do the same thing. I find that it has 1v on the PCH when off. The en2 pin on the NB689 has a 1v. Ic is on. This is not normal.
I would like to ask for schematic drawing and boardview.
Help me please
Thanks. -
