Your bios is corrupt, and also the DMI. Try the bios i posted in the post above yours or the one peste has suggested. If you want to change the DMI try the U1 tool https://www.badcaps.net/forum/troubl...24#post1622424Comment

I have a Lenovo Legion 7 16ACHg6 type 82n6
motherboard: NM-D563 rev 2
when i press the power button (whether plugged in or not) the icon leds on the back of the screen light up,the keyboard, the power button, and the fans do not turn on. I have to hold the power button to turn off the back leds. the battery charges fine. I think it might be the bios chip (i'm planning to buy a programmer). can anyone tell me where is the bios chip so I can flash it? if anyone thinks it's something else please tell me. I've tried clearing the cmos and holding the power button for a minute.
note: there is no ssdLast edited by oussamam; 01-09-2025, 03:51 PM.Comment

Hey guys, can you help me out?
One of my friend send me a legion7 mobo, which was dead for good.
He tested it after a keyboard replacement, its worked smooth, he turned off, than next day its never turned on again.
Its led indicators near the usbs are glowing up, when i press pwr btn they turn on, and stays on till i turn the mobo off. Its do the same with and without battery.
The cpu warms up sightly but no image on screen. I have found no shorts on board. Sadly i only have the mobo here with screen and battery.
Im usually into macbooks and i can edit those efis without problem, but this is a new horison for me. : D
Thank you!

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,
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... -
Hello frends,
