Hello! Here’s the situation: there is no image on either the built-in display or an external monitor connected via HDMI. However, I can hear the Windows startup sound. I suspect the issue is with the discrete GPU. I would like to switch to UMA mode, and I need help modifying the original BIOS. Thank you in advance!

Hi all, I need the correct bios bin file for:
Model: Legion 7-16ACHg6 Type 82N6
S/N: PF2YP66W
MB: HY763 HY760 HY762 NM-D563 Rev:2.0 2021-01-25
I already tried with post #5 but the laptop doesn't start at all with that file.
With the original BIOS file after inserting the charger, without battery, hard drive, wifi card, only with memory and coolers, I press the power button, the LED icons on the back of the screen light up, the keyboard, the power button, the coolers start spinning at the beginning slowly after 10 seconds strongly and the laptop turns off. The whole time there is a black image on the screen.
The memory has been checked on another laptop and is fine.

Hello everyone,
I’m 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, I’m 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. Here’s a full breakdown:
🧩 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:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. 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... -

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
