Accessing System Setup (BIOS) and Backdoor Passwords - PART 1

The BIOS/CMOS password can be reset most of the time by just taking out the battery from the motherboard for a few hours, sometimes only 15 mins. This can be a bit tricky on a laptop, so be careful.

If you bought a used computer chances you do not know the password to your system setup or to your BIOS. Many BIOS makers include a backdoor password that can let you get in. This list has some of the most common backdoor passwords to the BIOS and is intended for legitimate use only:

NOTE: Do not try to guess the password on a passworded Hard Drive. 3 wrong guesses will often result in the information on the hard drive being lost forever.

NOTE
Most laptops cannot have its BIOS password bypassed with any of the above backdoor passwords. The laptop passwords are stored in a separate chip, and clearing CMOS or removing the battery will not work to get rid of them.

A good article to read about this topic can be read here:
Removing a Bios - CMOS Password
http://www.dewassoc.com/support/bios/bios_password.htm

The CMOS jumper referred to in the two articles I mentioned above is almost always near the battery of the motherboard. Use the jumper by moving it over for about five seconds. Then move it back (release it). By doing that most BIOS will be reset. This is much faster than waiting for all the power to drain. Some newer boards even have a button instead of a jumper.
