How to Reset a Forgotten Dell Administrator BIOS Password
BIOS passwords are a convenient way to secure a computer, but unlike most Internet passwords, they are impossible to recover. Maybe you inherited a Dell from a family member and do not know the password, or perhaps you own the computer and forgot the password. Regardless of the situation, resetting a Dell BIOS password is a simple process. Although it does require opening the computer, no knowledge of PC repair is necessary.
Things You'll Need
- Small flathead screwdriver
Unplug the Dell and hold the power button for 10 seconds. This will ensure no electricity remains inside the PC and protect you from electric shock.
Remove the side panel from the computer. You will see the motherboard. To reset the password, you will need to reset the motherboard.
Find the CMOS battery. It is a silver disk about the size of a quarter. Its location varies by Dell model, but it is often located near the white PCI slots.
Pry the CMOS battery out with a small flathead screwdriver. Wait a few minutes and replace it. This will reset all motherboard settings, including the password. Put the cover back on the computer.
Tips & Warnings
- Resetting the motherboard will return it to its original factory configuration. Any setting changes previously made will be lost.
