Hi everyone,

Could someone please help me remove the Supervisor password?
I attempted to use an autopatcher, and now when I try to enter the BIOS I get a black screen.

Good for you to help others (@KELO1981)...but we have rules here...for next time 😊...

Like "...Provide the full machine model number, serial number (or Service tag, SNID) and the board model number (see https://www.badcaps.net/forum/showthread.php?t=88758 ) ,The serial number, make, full model number, motherboard model and revision (except QR codes) must be written/typed at your request as per the rules. Not as a picture, part of the file name and so on...."

First time posting on here. Just wanted to say, I used the CH341A (had to do the 3.3v modification) programmer with this method on patching the .bin and re-flashing followed the instructions to the T and worked great. Had bought a Lenovo Thinkpad T460 with a winbond W25Q series EEPROM chip. I struggled for a while to remove the supervisor password with HxD editor and ASprogrammer and struggled. Had to use Flashrom to connect through the terminal to the chip (this worked better than ASprogrammer) But glad I found this. thank you.

Hi guys,

I came across t14 gen2-20w1 and found that if we use a clean me file that doesn't work on other laptops, could someone please tell me what difference is between this laptop's bios bin and others?
Both laptops are 20w1, but the file doesn't work.
Is it something related to the EC chip?

I've seen a few users reporting problems about "cmd closing imediatly after open the autopatcher". For those who are having this trouble, just try an older version of Python. I had the same trouble, but I fix it using the 3.13v. Glad if helps a little

Hello. I tried this in 3.13 but it didn't work. Is it because it's 32MB or is it an incompatible program?

Type the laptop serial number, full name and model, motherboard model, etc.

After some trial and error, this has worked. (I'm currently flashing the original BIOS back)
I'm not entirely sure how, but, on an L480, I managed to get past the black screen issue after reflashing the original bios and then the patch again, at which point I could get to the lenovo screen. To enter BIOS options, I tapped the BIOS key (Enter in my case) right before the splash screen showed, as after that point it wouldn't work.
