Fujitsu Lifebook Tablet T4210 needs Phonenix BIOS reset. I took everything apart and removed the CMOS battery for 30 minutes. Then I put everything back together, booted up, and BIOS asked me for a password again. I tried the default/backdoor passwords I have seen for Phoenix and none of them work. Is it possible that I did not leave the CMOS battery out long enough for the RAM to lose charge? What else could I try to do to reset the BIOS (as far as hardware options)?
