Hello, I have this specific laptop model where BIOS is locked. I tried to find EEPROM but I found two of them similar types. They are labeled in the board as U15 and U49 . I do not know which one I need to short to disable the BIOS lock. I tried both but it did not work. Am I missing something
I cannot vouch for these on a modern Thinkpad, but Christophe Grenier’s other programs are legendary in their quality: https://www.dataimpact.nl/blog/removo-le… It looks like they’ve had success here with T430m T520 and T530 models, so maybe this method will work? This seems to have worked on T470 models: https://www.badcaps.net/forum/showthread… CmosPwd: https://www.cgsecurity.org/wiki/CmosPwd There’s a forum there on which you might ask about your model.
