Support for Asus ROG G73 rev2 Bios/Schematic?

[magneh]

Hello!

Got this beast in a quite bad shape ... touchpad ribbon cable with a burned track ... whatever.

The owner said he bought it like this ... he said also that sometimes the laptop would POST and he entered the bios one or two times, but most of the time there's no VIDEO.

Well I tried a reflow on the GPU, and it when shorted after. Reballed it and short was gone.
Assembled it and it turned on, fans spin, and no video.
2nd time the same. A few hours I turned it on and I got image with ASUS first image, but with blue tonality.
I could get into BIOS and selected Default setting and saved.
Never got image again the few times I tried to turn it on.

This is a garantee that's not BIOS issue neither GPU?

This said, and I've tried hard to find BIOS os schematic, but no luck.
Could some one help me with this?

Some photos attached.

Thanks!

i bet on gpu! relowed 3-4 of them... never had any other issues, only vga... and always use asus vga driver its different from ati vga driver, you will have freeze/bsod issues.. on some versions of bios lan disappear from device manager, but clear cmos fix this

if you get it working flash modded bios, you will get voltage settings and fan speed settings in bios

Hello!

Well I've tried to make some more test to this MB and here what I've found.

First, I could never get the board to POST and show video again.
Second, when I plug charger board powers up all by herself. If I press PW some seconds she shuts down. And if I press again, she turns on.

This behavior is not 100% garantee. sometimes I plug the charger and the board DOESNT power up by herself.

Mesured coild on GPU (see photo) . arent some too low?
Well, removed GPU and black pastic protection that was underneath her , and I saw a burned component.

The question is that it isnt labeled, and It's impossible to read PN.
I bet it's similar to the one next to it... I had to leave office and I'll check it better tomorrow.

Here are some pics.
How do you guys proceed in this case to know what PN is it?

Thanks!

Hello!

Any one with more experience on these GPUs could tell me if those values on coils arent too low ?

How to correct identify tht burned IC without schematic?

Thanks for any inputs!

Cheers.
