Sorry for late reply I had to order new programmer as it is 1.8V chip. Unfortunately after programing with new bios same issue. It's charging but not powering on. Once power button pressed laptop goes into the loop with power light coming on for 10sec and off. I will keep looking for hardware issue.Comment

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

Hello everyone,
Iโm 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, Iโm 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. Hereโs a full breakdown:
๐งฉ 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

Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:

It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered...
