Hello everyone,

I’m working on a Lenovo ThinkPad 10 (1st Gen), models 20C1 / 20C3, with motherboard LA-A811P (ZIJI2). The device is locked with a Supervisor (BIOS) password, and unfortunately, I do not have the password.

Here’s what I’ve tried so far:

• Extracted the BIOS file from Winbond 25Q64FW1G1416 chip.
• Attempted to use an auto patcher, but it reported the file as corrupted.
• Used UEFITool to inspect padding areas for password data, but no success.

I’ve attached:

• Photos of the board, chip and locked UEFI.
• The extracted BIOS file.

Is there any work around for this. I bought a set of Lenovo think pads off an auction site and the seller don't have the password.
