Replace your CMOS battery to reset the BIOS password.
The CMOS battery on your ASUS motherboard controls all of the BIOS (Basic Input/Output System) processes when the computer is turned off. If you are locked out of your computer's BIOS menu because you've forgotten your password, you can reset the password by replacing the battery. When you disconnect the CMOS battery from the ASUS motherboard, all of the presets on the computer, including the password, will reset.
Instructions
1. Unplug all of the electrical cords from the computer so it will not turn on while you are working on it.
2. Use a screwdriver to remove the screws on the back of the computer to open the computer's tower.
3. Locate the CMOS battery. The CMOS battery is going to look like a watch battery. It will be small, round and silver. Consult your ASUS motherboard's manual for the exact placement, but you should be able to eyeball it.
4. Press the release lever on the side of the battery to remove it. Replace the battery with your new one.
5. Replace the tower door and the screws holding it onto the computer casing. Plug the computer back in and turn it on.
6. Watch the computer screen and follow the prompts to enter the BIOS menu.
