My fujisui siemens laptop amilo pi 2550 has a bios password which i cant remember and now i have check sum error replaced battery but cant get back into bios to reset clocks etc and will not boot to windows
it use phoenix bios v1,11c
Take out the battery for longer. It seemed to reset by indication of checksum error, but for an odd reason its still passworded. Remove battery and this time short the battery contacts on the motherboard and make sure no power or battery is in the machine. Then replace the battery and give it a shot.

tried all of the above already still asks for password
RESOLVED PROBLEM MY WINDOWS PASSWORD WAS THE SAME AS BIOS PASSWORD FOUND OUT THAT THE PASSWORD IS HELD BY EEPROM CHIP SO TAKING BATTERY OUT WILL NOT WORK.
