Thank you so mush. Been able to remove password on second hand A475.
Did that on Linux Mint though, as the script refused to do anything on Windows even though Python 32 and 64 was installed (tried on two laptops one with fresh install)

Hey guys, could I please check if the autopatcher can be used on T14s Gen2 thinkpad to remove the BIOS password? Or LPC bypass method should be tried on these newer thinkpads?

if you put back original bios laptop starts?

[IROC2022]

Yes when I put back original file the laptop starts and goes to the password prompt. I entered any password but no luck. Could be the patch file is not working properly.

Hi everyone,

I just managed to unlock the supervisor password on my T480s.

PC model: 20L7001NMZ
Motherboard: NM-B471
BIOS chip: WINBOND 25Q128JVSQ

I used a CH341A with an 8-pin clip directly on the chip (soldering isn't my thing).
I used NeoProgrammer v2.2.0.10 because I couldn't find my chip in either CH341A Programmer or ASProgrammer.

Using the 8-pin clip that comes with the CH341A was a real pain — I think there were contact issues, and I had to reposition the clip several times before NeoProgrammer could detect the chip. It took quite a while each time I wanted to connect it, but eventually, it worked.

It wasn't smooth sailing; I ran into a few problems. Honestly, I don't fully understand what I did, but in the end, it worked! Here's a step-by-step of what I did:

1. Backed up the original BIOS chip to a .bin file
2. Ran the autopatcher script, which created a "_PATCHED" .bin file
3. Erased the chip and wrote the patched file
4. Turned on the computer

At this point, the laptop started beeping weirdly (beeps with different noise levels 5 or 6 times) with a black screen, then shut down.
Tried this a few times — same result every time.
5. Flashed back the original BIOS file — the laptop was back to its initial state. Not bricked, thankfully.


A bit desperate, I tried something else, not really knowing what I was doing:

1. Downloaded the BIOS file shared by Stefan Steff on this thread (4th post) :
   https://www.badcaps.net/forum/troubl...20l8-bios-dump
2. Booted the PC with that BIOS file — it struggled a bit, rebooted once or twice, then asked for the Supervisor Password
3. Exported the BIOS from the chip again and compared it to the original Stefan Steff file — it had changed
4. Ran the autopatcher on this new BIOS file, then flashed the patched version to the chip
5. Followed the patch usage procedure:
     - Boot the machine
     - Press ENTER/F1/etc. to enter BIOS
     - Type any character for the Supervisor Password
     - Press Enter when the Hardware ID shows
     - Press Space twice when asked
     - Power off
6. Finally, I reflashed Stefan Steff's BIOS file — and voilà: no more Supervisor Password, and the PC works perfectly.

Don't ask me why I followed this exact process — I'm not sure myself — but it worked for me.

Hope it helps someone!
