Hello everyone,

I need help with my Lenovo Legion laptop BIOS. The situation is the following:
  • With the original 16MB BIOS dump the laptop only gives a black screen, there is no initialization.
  • If I flash other BIOS versions, the laptop boots, but the NVIDIA GPU shows error 43 in Device Manager and the VRAM is detected as 0 MB.
  • I already tried replacing NVRAM, cleaning ME region, and using BIOS from update files — but none of these attempts fixed the issue.

It looks like my original...
