Legion 5 15IMH05H Type 81Y6 BIOS HELP

Lenovo Legion 5 15IMH05H
S/N: PF1BTUHM
MTM:81Y600DCUS


Laptop crashed in a bios update, now boots to a black screen, I flashed a new bios and it is still the same albeit it doesn't crash after a few seconds now.

I dumped the original BIOS file with my CH341A programmer.

Would appreciate any help

Here's your New BIOS, it's a Virgin BIOS from Lenovo with your DMI and Windows Key.

Thank you for replying.

I tried the BIOS and the issue still persists, it's a black screen and does not boot into anything. The fans do ramp up now on full speed and then it crashes.

FYI this is my bios chip and the software I am using (Asprogrammer does not have 25l12872f, only 25l12873f). I unplug the CMOS battery and main battery before flashing, I cleared it before writing and also verified after. Once I boot the bios is different from the virgin one but I am guessing that is what is supposed to happen.

I guess it's also worth mentioning that I suspect the GPU on my laptop has an issue which is why I updated the BIOS in the first place. Is it possible that the BIOS is booting into discrete graphics mode only? Is there a way to change that without a screen? (I tried external monitors, but no dice)

Try NeoProgrammer V2.2.0.10 , it does support 25l12872f

Also try with older version of the bios, look at the fist page of the thread.

I tried the programmer and the bios hardware1 made and I managed to get it to the original issue where disabling hybrid mode would cause the black screen issue. I did some stupid maneuvers to disable it within windows but now I can finally see the screen!

Thanks!

Now to fix the 2060 vbios

Hi, I noticed the S/N on the BIOS you provided does not match the S/N on the bottom of the laptop. Did you accidentally post the wrong file or was the BIOS modified before?

No, I made it for you. Perhaps someone changed the Laptop Bottom Cover, or your BIOS file wasn't the Original Backup.

Hi, will this bios work instead of the attached bios? I believe the version is EFCN59WW.

I have already tried it, but the screen remains black. So, I just wanted to confirm that is should work. If not can someone help me with the correct bios?

Hi,

Thank you for being so helpful. Unfortunately, the problem is still there. I compared your BIOS file and the backup BIOS, and they are very different. If the original BIOS was corrupted, this would make sense. But why is the problem still happening? Am I missing something, or could it be a hardware issue?

If the screen is the problem would I still be able to get an HDMI output on this model without the laptop booting into Windows?
