And would it be possible to repair the bios even if you keep the password? I only want the laptop to start the system ... if it is not possible, thank you very much anyway

Hello, I have a T440s with BIOS version 2.51, a few days ago I tried to remove the Bios password by doing a tutorial in which I made a short on pins 5 and 6 of the chip during boot to disable the boot password verification and power change the password of the bios. After some unsuccessful attempts the laptop stopped loading the bios and the screen remains permanently black, I do not know if it damages the chip or the data of the bios, but through the CH341A programmer I get a backup of the bios, I hope that can you help me https://www.dropbox.com/s/zsm8rxgbogv29na/bios original thinkpad t440s.rar?dl=0 Try installing a new Bios (I found version 2.35v) and the computer is already booting, but it gives me two errors 0271: real time clock error 0183: Bad CRC of security settings in EFI variable. I can not get through the bios. My laptop asks for a fingerprint at startup, my fingerprint is set, so that's not a problem.
