Hi everyone, complete noob here. I would like to get rid of the supervisor password of a recently purchased T480.
Type 20L6-0014SP
S/N : PF-0ZW20U
P/N : SL10Q67055
I managed to read it using a CH341a, but failed in using the autopatcher.
I suspect the file may be corrupted.
Many thanks in advance

Yes your file is corrupt it is empty ....

file was unlocked correct. Put back original bios and see if laptop starts, if not it means your read of bios chipset was defective.

The flashing original BIOS dump restores the laptop to working condition. How can I remove or disable Absolute/Computrace?

Hello.
Have this Lenovo T480 NM-B501 that is not charging. USB-C stays on 5V, Mechanic USB-C tester shows that both ports are ok.
Read about u15 bios corruptions. i try to make and flash new bios but it did not help, maybe because it needs HEX editing which i sucks in.
maybe somebody allready doing this can help.

Exactly, so why ask in this thread when its a dedicated thread for the T480, as it says in the thread title. 22 of your posts have been deleted already for off topic requests and hijacking threads.........



Yes, its not a T480 is it. Hasn`t it occured to you that you should be asking in a 645 G9 thread. Why don`t you use the forum seach engine, you should find a 645 G9 thread, and before you post your request/question you can read the other posts and see if anyone else has had their bios unlocked or not.

OKAY ..
