Hello everyone,

I have now created a patched version of my bios dump using the Lenovo Autopatcher.

Unfortunately, the notebook only emits a few beeps when starting up and otherwise only has a black screen​ (according to the Lenovo app: Error 285 - function-related TCG compliance problem).
With the patched Bios-File the notebook is not working :-(
Then I reset the TPM module (clear-tpm -useppi), which i have read in one Thread.

I then re-flashed the original bios dump - then the notebook works again - but unfortunately with the bios password....

So, I've read it several times and compared it.
Now both the CRC is correct and Diff says the dumps are the same.

I hope this file fits now.​...

Hello everyone,

I have an older Lenovo Thinkpad E590 for which I unfortunately forgot the BIOS password I used.
I managed to read the bios with the CH340A. There are a few videos circulating on the Internet in which the password is decrypted - unfortunately I couldn't find it at this point in the dump.

What options do I have to reset the bios password?
I have attached a dump of my bios.

Notebook type:
Lenovo ThinkPad E590
20NB-CTO1WW
S/N: PF-1NTXHP
Mainboard: MN-B911, Rev. 1.0

It would be great if someone could...
