Hello everyone,
It seems like the issue with black screen and error code 0285 is more common that I thought. Has anyone figure out a way how to get it to work? I'd really appreciate any help.

I've tried almost all the combinations and I still get the 0285 error with black screen, with/without hard drive, with/without holding the tamper switch, with/without the CMOS battery plugged in, the only thing I have not tried is removing the RAM. Does that matter? I also cleared the 1.2 TPM from the app and using Power Shell....Leave a comment:

First off I want to thank you for your help. Unfortunately this one didn't work either. I checked the error tone with the Lenovo diagnostic app and it's 0285 TPM initialization error....Leave a comment:

I tried my backup after the second failed attempt and it works fine, laptop turns on and I was able to go to the BIOS settings without an issue, however the supervisor password is still there. Just to double check, do I need to do anything to the file you sent me or just program the BIOS with it?...Leave a comment:

I used the patched file you provided and updated the BIOS with AsProgrammer, but it still plays the melody and no screen after. Am I missing a step or doing something wrong?...Leave a comment:

Hello everyone,
I recently bought a couple of used Lenovo Thinkpad laptops and I came across this forum while searching for solutions on how to reset the password on my BIOS. I'm looking forward to learn from you all and hopefully get to a point where I can contribute and help others.Leave a comment:

Hi,
I did the autopatch for my T470S and when I turn on the laptop it plays a melody once and screen is back. Please see my original and patched BIOS files attached.
Thank you...Leave a comment:
