i am not sure how old that site is but you can't reset any computer's bios any more just by pulling the battery, and this has NEVER worked on laptops as they store the password on a completely separate chip encrypted. Home pcs haven't had the ability to be reset this way in years ever since bios chips started using flash memory. There is a jumper on motherboards that erases that flash memory, thus resetting the bios. If you are dead-set against cracking your case to move that jumper then your only other option is to run a dos-based program that can read and decode your bios, as the password will almost always be stored unencrypted. Supposedly the program listed in his link above can recover them if ran from a cmd prompt, but i suspect this won't actually work unless you open the cmd program with administrator access because windows won't let it get direct memory access otherwise.
