HP Pavilion G7 1045 SF schematic needed

[Scootie]

I've got this laptop, pretty beaten-up but it starts on without problem. Oh well, no screen on either main or external vga. The vents were really cloged badly so I suspect the vga chip cip, 216-0809024 is either burned or doesnt get enough voltage, it's stone cold even after 2 minutes after the laptop has been powered, meantime I change cpu/ram but to no avail. I'm missing this schematic from my collection, can someone upload one for me so I may try and test this motherboard?

Thanks.

Give me a model motherboard.

Yes, I knew that it will be bite me in the ass if I dont provide one but I was already home when I made the topic. :P

HannStar J
94V-0
MV-0
1104

Also, I think some parts might be missing on the picture taken of the board.

HannStar J - It is a manufacturer of PCB.
PQ2 - maybe it's 2N7002D

Re: HP Pavilion G7 1045 SF schematic needed

PQ2 is in the power circuit +VGPU_CORE

Then it might be this one: DA0R12MB6E0 REV: E

Thanks for the schematic and the picture. Will try and figure out what those missing parts do.

Re: HP Pavilion G7 1045 SF schematic needed

Good luck

Re: HP Pavilion G7 1045 SF schematic needed

Alexnavin, any chance to help me out with the values of that PQ2 component? We cant seem to identify a proper one so we need to know what's written on it.
Thank you.

Thanks for all the help. I managed to replace what was missing and the laptop turned on with screen this time.
Now I found some more missing parts, some small smd's. I will try and fiind replacements for them although I dont know yet what they are for.
