If none of the backdoor passwords mentioned above worked, you can try the one below. They work for mostly all PC desktops and may or may not work with some laptops (in some laptops, using the procedure below may trigget a "hardware security lockup" and the laptop will not boot up afterwards; use at your own risk):
1) Shut down your computer or laptop (DO NOT HIBERNATE OR STANDBY)
2) Unplug your computer or laptop
3) If you have a laptop, also remove the battery or batteries
4) Open the bottom cover of your laptop or the side cover of your computer
5) Remove the BIOS battery (it's usually round, silver color and about 1" in diameter)
6) Wait at least 10 minutes
7) Replace the BIOS battery
8) Reinstall the cover
9) If you have a laptop, replace the battery
10) Replace the power cord and restart
The BIOS password should have been cleared
