Re: Lenovo ThinkCentre M920q 10RRS1J80H Bios Password

Hi, have you tried to reset CMOS? On page 36 (pp.40) it says: If the coin-cell battery fails, the date, time, and configuration information (including
passwords) are lost, so I guess that by disconnecting it, it will clear CMOS and passwords. There is at least a post for another ThinkCentre model on this forum and that's the procedure they describe.

If clearing CMOS does not work, then first of all make sure you have a good BIOS backup before programming this patched file.
I was trying to understand the code in order to recover or generate a matching password, as the password seems to be hashed into AMITSESetup uefi variable.

Thank you very much for your answer. I tried resetting the CMOS twice. Time is lost, password remains. I will try your BIOS.

@redcayote
"AMITSESetup" variables containing password were invalidated.
Just the chip W25Q128 needs to be updated with this new file.

I need help with the same problem. The ebay seller I bought the m920q from doesn't appear to know the password, and while it's been reimaged with a fresh windows install I want to put proxmox on it and I cannot disable secure boot.

I can boot to windows, though, how do I dump the bios file for tweaking?

Or will any bios for a m920q work?

Hello,

Just got the same with 910q and to make it work you have to update your bios first then the jumper method is working fine

Hi here is my BIOS backup.

Use programmer to get bios, do not use software.
