reset the BIOS password on a Dell Optiplex 755

From time to time, you may have the need to reset the BIOS password on a Dell Optiplex 755. You may have forgotten the password. Or perhaps the person who entered the password forgot it, moved to a different job, or died. Or even worse, maybe some obnoxious prankster decided to set a password and not tell anyone.

Fortunately, it’s easy to purge the password. It just takes some moving of a jumper on the motherboard. Here’s how:

-Shut down your computer and unplug. For reasons that ought to be obvious, rooting around inside the computer while the power is on is a really stupid idea.

-Open up the case, and making sure to ground yourself, look at the motherboard. The jumper controlling the password will be labeled PSWD, and is usually blue. Gently removed the jumper.

-Plug in the computer and power it on again. You should get a message saying “password removed”.

-Power the computer off, unplug it, and restore the jumper to its original position.

-Turn the computer back on and hit F2 to access the BIOS. The password should be gone.
