Steps to Reset the BIOS Password in Dell Computer

Before we begin with the reset procedure, let’s understand what BIOS is. It is a built-in program called Basic Input\Output System (BIOS) that loads automatically when a computer is powered on. The program manages data flow and controls all the attached or built-in hardware or applications like keyboard, mouse, printer, router, serial communications, disk drives, and monitor among other things. It is usually located in the pre-integrated ROM chip (aka ROM BIOS) in a computer. The steps described here are simple and correct until date. However, it is still recommended that these should be followed carefully to avoid facing problems. This will help users save their precious time as well as money. If  you  face any problem in performing below mentioned steps, You can call  Dell technical support at their toll free No. +1-877-452-9201


First, locate the user manuals that originally came with your Dell computer. Search through the pages to find the component structure of your Dell PC as you will have to pull out the CMOS battery (silver colored) from the motherboard. If you are not sure what to do, open your web browser and go to Dell’s official website. Type in your computer’s model or version and navigate to the Service Manual option. Look throughout the options and locate diagram or graphics of your PC’s motherboard. Either print the information or note it down on a piece of paper as you will need this while the computer is shut down.

Now turn off your computer and detach the power cord from its back. Detach all other connected devices like USBs, printer etc. Open the case of your computer, locate the 3-pin CMOS battery and remove it. Hit the power button and hold it for 10-20 minutes to drain the leftover charge. This will clear the previous settings and make way for password reset. Close the computer case, reconnect all the devices, plug the power cord back in firmly to the computer and turn them on(see also:How to Reset BIOS Password in a Dell Laptop).

When the computer is turning on and you see the Dell logo, start tapping the F2 key on the keyboard until you see the Entering Setup message screen. Some old Dell machines may require different key combination in place of the F2. This combination includes pressing Ctrl, Alt, and Enter keys together and then the Delete key on the keyboard. When entered, make a new password as desired. Write this down on a piece of paper and keep it a safe place. This will save you from falling into such a situation again.
