Thanks, this worked....

Hi, this file boots the PC.

I follow this procedure, but I get stuck at step 5.
When the hardware ID appears, whatever I do is invalid password.

I can't proceed.

STEP 1: Flash and replace current BIOS with the P50_Bios_2_PATCHED.bin file
STEP 2: Boot the machine

STEP 5: Press enter when it shows Hardware ID
STEP 6: Press space bar 2x when asked
STEP 7: Turn off machine
STEP 8: Restore original P50_Bios_1.bin...

I tried the file you shared,
I wrote it and verified it was written correctly.

It has the same problem as above: it beeps 5 times twice, the fans spin for a few seconds, and then shuts down. No signal.

rewriting my original, it goes back to how it was before with the password....

Hi everyone,
I'm trying to remove the bios Password from my ThinkPad P50.

I have tried both lenovo_autopatcher_0.2 and the older lenovo_autopatcher.

- Windows 11

Hello everyone,
I’m interested in laptop repair and BIOS programming, and I recently started learning how to use CH341A programmers.
At the moment I’m working on a Lenovo ThinkPad P50 with a Supervisor Password issue, and I hope to learn more here and share my experiences.

Thank you for accepting me into the community!...

Hi, I have a ThinkPad P50 I bought used on eBay, with an invoice from the seller. The seller doesn't know the password, and I need to remove the BIOS password. I have the CH341 flasher purchased from Amazon along with the 8-pin clamp. Can you tell me how to extract the BIOS and then decrypt it?
I also need to identify the correct chip to read.
MB model: bp500 nm-a451 rev 1

Thank you for your attention...
