Hi,
This is my first post and i am new member on this site so take notice.
That's my first jurney with ACER. Whatever. I bought laptop with burned off mosfet PUA1 and PUH1 and in consequense CPU i7 10750h.
I was raplaced CPU from omen hp mosfets and machine ran!
Fans working, making post, all voltages presents but not that.... VCC_GT. (May it up when system is on load? after RTX working?)
I think that is BIOS. I am writing clear bios Me Region all sh..t not working.
2 reset, keyboard backlight blinking and stuck.

I am tray to solder new BIOS, new firmware ...nothing.
After few reprogramming BIOS on board motherboard stuck and waiting for PM_SLP_S4#,... nothing is here.
I was replaced PCH SRH8Q from other board(booting) and.... nothing.... still no PM_SLP_S4# and 3.

I dont know what to do. I unsolder KBC to check firmware but it's look ok for me.
All sheets and brd Do you have from this link

My sugestions:
- bad PCH cause you dont have PM_SLP_S4#
- bad firmware BIOS maybe you have good

Please describe the problem as short as possible, don't write too much that will confuse others and note that we can only help with problems related to BIOS, about hardware that need to be checked directly...

I need BIOS for my motherboard. I dont have any backup.
