LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Wow ! thank you for this quick feedback and (the anticipation of the questions)

Sérial number : PF-2T7VT2

so if I understood correctly, it doesn't happen at the bios level but at the "EC" level... what is that? I read the post carefully and I didn't see where the chip in question was located

it's a big square chip next to bios and keyboard connector probably or on the other side
maybe an ite8227e

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

ok so the CH341A will be of absolutely no use to me for reading/writing the EC

And still, if I understand correctly, there is no alternative to using a Vertyanov adapter? or maybe here: https://www.badcaps.net/forum/showth...=111439&page=2 with an RT809H but for a single troubleshooting it's not cheap. Or is there another solution that I missed?

There are still things to do to finish

It would be great if you could use the ThinkPad maintenance utility to bypass the password and use eeprom init to clear the EEPROM if the super administrator password was set

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Could this application even allow you to delete the password even for my model? I have the impression that it only works via a USB boot first and I cannot change the boot order... precisely because I do not have access to the bios, even this option is blocked. I imagine it can't be run on Windows?

I don't know if you can help me by installing the patch on Lenovo L490 and the machine just beeps and doesn't show an image.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

I just want to post to say thank you to @Knucklegrumble for this great tool. Thank you very much.

My ThinkPad T470s 20HF was bricked after recent BIOS update through Think Vantage from Lenovo. I can only see the keyboard lights flash and hear the CPU fun spinning after the failure. The screen will not light up. This was fixed by reflashing the BIOS using a new bought CH341a programmer and BIOS bin file from this thread.

But it only takes me to the Supervisor Password enter page for BIOS setting. I am sure that my Supervisor password is correct. However, the system prompts error. After a few times of tries, I found this magic tool. I used this tool to patch the BIOS file downloaded from this forum and it worked. The Supervisor password was cleared and I could use my laptop again finally.

Hope this information helps.

Thank you all for this wonderful forum.

Clean the ME firmware on your original bios,sometimes that works.

When the PC gets tired of playing, it no longer even asks for the password yet still writes

Don't ask me, I don't know what I did, a few random conditional jumps
