I have bought a used Fujitsu Lifebook T4220 tablet, but the previous owner has set the owner information in the bios, and it can't be changed after setting it, how can i remove, reset or change it?

I just find out this decoder tool for many laptops as they claim, maybe give it a shot: IBMpass v2.1 Lite — Password decoder & scancode editor for eeprom dumps (Freeware) and let me know if it works! – Miro co Oct 16 '11 at 16:12
BIOS Type is Phoenix TrustedCore v1.12 if it useful. – Mohamed Sakher Sawan Oct 16 '11 at 16:41

Its necessary that you define a supervisor password. After that you can change the owner information and then set the password back to clear. Then its changed.
