Hi everyone,
My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
Laptop stopped booting entirely.
I used a CH341A programmer to dump the corrupted 16MB BIOS.
i then attempted the following:- Downloaded stock BIOS BHCN39WW from Lenovo
- Trimmed it to 16MB
- Extracted the BIOS region from the corrupted dump
- Extracted the BIOS region from the stock 39WW
- Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
- Injected back my LDGB / DMI

Hi !
I tried to enter BIOS and it hangs (it shows a line on upper left corner) . When I push the BIOS button on the right side , I get a menu where I can select between normal startup , bios setup , boot menu and system recovery .
I choose bios setup and it hangs (the same if I push F2) .
What to verify ?
Thanks !07-21-2025, 08:45 AM -

Hello everyone,
Iβm currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, Iβm at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Hereβs a full breakdown:
𧩠Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows
