Copy the DMI from your backup to the new one using a hex editor. Search for the word LENV , the off-sets are 223000 - 224FFF

Hello
The laptop has a BIOS password that is not recognized after a BIOS update. I have downloaded some files from the forum and the computer boots fine but the Lenovo website does not recognize the computer and the updated processor and video drivers cannot be installed. What solution could be effective for this case? Thanks

Upload the bios file here, do not use external links, use winrar or 7zip to compress it before uploading, remember serial number.

Hi, just wanted to thank you for the help. I was able to get back into my laptop. Some keys, like ESC and A, don’t work, but everything else is fine.
Thanks again, I really appreciate it!

Cheers,
