LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[mitchw]

Hay Can I have that T470 BIOS dump from 2018 or maybe directly the patched one? I have T470s and is locked. going to try on that.

I don't have it here as I am on vacation now. Try finding one online... there are multiple posts of people asking for unlock and providing their dumps. Just pick one that is bit older and run a patch on it, then write it to your chip and boot the pc. After that remember to restore the original dump back!

Found solution, used another locked bios dump for T470 from the internet from 2018, applied patch on it and wrote it to my BIOS chip.
Then it did its magic.

After that, I rewrote the original BIOS and reset it to factory defaults.

And it worked!

I am guessing that the autopatcher does not work anymore on newest BIOS revisions as mine is version 1.79 from late 2024 - the latest one. But it did work on older ones, so the version from 2018 worked.

I did exactly the same on my T470 and it DID NOT WORK! I got the black screen and a musical melody played! I flashed the original BIOS back and now it is booting again but still LOCKED! What I need to change? I followed the instructions by the letter!

This worked perfectly. Thank you SO much for your help! It's my first time doing anything related to BIOS chips and I'm so glad there's a community of helpful people like yourself.

You're welcome.

Hi all,
Thanks for your work on this.
I can't seem to get the patched BIOS to work.
I'm working on a Thinkpad T480.
S/N: PF1HZZPP (on sticker on case), System-unit S/N in BIOS is PF1LEPXM
Motherboard: NM-B501
BIOS Chip: Winbond 25Q128JVSQ

I selected the W25Q128JV chip type in AsProgrammer.
Downloaded the BIOS x 2, compared hash values and it was good.
Applied the patch.
After flashing the patched BIOS I just get the loud musical tune and a black screen. Never any words appearing.
Re-flashing the original BIOS makes it work again, but it still has the BIOS password (as expected as I never did apply a successful patched BIOS).
Any ideas? I had updated to the newest BIOS from Lenovo for the T480 before going through this. Could that be the issue? My BIOS version is: 1.55.
I've attached my original BIOS and the patched versions.

Thanks in advance for any help you can provide.

I have one Lenovo X395 (japanese) and need remove Supervisor Password.
I read my BIOS (25Q80DVSIG) but I get a error when try to patch (BIN and HEX).


Model: X395
Type: 20NM-S1PG00
SN: PC-1FBBDX

Try with UC3 (near WWAN1 connector) and if it's W25Q128FWSIQ then it works with 1.8V

Need help removing BIOS password from my Lenovo T480s 20L8
Serial : PC0V3ZRN
Motherboard: ET481 NM-B471 Rev 1.0
I tried using the patched but after programming the chip. Laptop did not turn ON and when i connect charger. Power button flash 3 times and then nothing happens. I programmed back the original file but it showing the same symptoms.
I removed the chip from the motherboard.

20L8-S4S00

I suggest you remove the battery, unplug the button battery, wait a minute, and then plug the button battery and main battery back. Now you should be able to post. That's how I solve similar situation today.

I have a T480s running Windows 11, everything is working, but the BIOS is locked. So I purchased a CH341A programmer, read the chip 3 times to make sure it's right, and then patched it with the auto-patch tool. Unfortunately, the laptop refused to boot and played a melody. I had to write the original bin into the chip; otherwise, I can not use my laptop.
Would like to know why and how to patch it properly, files provided.
