@hoaca388 i have been testing and i found issue with D-GPU, while gaming it randomly disconnects (disconnects as in sense as like it disconnects from PCIE) i am sure as i am connected external monitor on D-GPU and when it does disconnect the external monitor will be blank and laptop monitor (i-gpu) i can see its trying to reset the display adapter. do you think does it have to do anything with this bios or any idea on why this is happening. this issue is after this bios corruption and also strangely my d-gpu dosent disconnect/crash when i stress test heavily. but it crashes on games with low graphics, esp when it load terrain ...

I don't know why but it's probably not related to this bios, it's the original bios and the only windows key is yours.

Thread merged. Post your bios backups and type as text the laptop serial number.

The problem is that there is no serial number anywhere, because that's how I got the laptop!
All the Type / SN stickers have been removed!
I only looked at the inscription under one of the RAM memory chips
