Panasonic Toughbook CF-20 CF-20C5141TN Can we unlock? Bought from ebay and unfortunately it was not possible to reset the password. I disassembled the laptop completely, removed the memory chip, took a dump. Inside I looked for information AMITSESetup. Found 5 places where in theory there is a password (including duplicate, reserve areas). However, after completing all the steps, I loaded the updated BIOS, unfortunately the problem remained.
