I believe you force BIOS to think that it had been lucky but checksums don’t match and EEPROM save is corrupt, then load default and let password go.

Works for straightforward ones like most Lenovo, but not for weirdos like Toshiba. Sometimes I see lots of Toshiba office laptops with locked BIOS waiting to be recycled as the result.

Older Toshibas have pins near the RAM that can be shorted to clear the passwords. There's a big list here: https://biosbypass.com/how-to-clear-toshiba-bios-password/
