How to Bypass or Remove a BIOS Password

A BIOS password is a protection measure that can be used to stop someone powering up a computer system or making changes in some of the computers most sensitive areas. Many big name computer manufacturers such as Dell and HP lock the customers out of this area because they don’t want the customer changing anything and potentially damaging the machine (which the manufacturer may have to warranty). However, when someone like a computer technician or hardware enthusiast needs to make some hardware changes to the computer, they will need to access the BIOS. Here are some methods to be a bios password cracker, removing a BIOS password.

How to Bypass or Remove a BIOS Password by Removing the CMOS Battery:
The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.

Steps:
1.Power off the computer and make sure that it is unplugged. 
2.Open up your computer case. You need physical access to the motherboard to complete this procedure.
3.Find a circular, (mostly) silver metallic object on the motherboard. This is the CMOS battery.

4.CAREFULLY remove the CMOS battery and leave it out for about 120- 180 seconds. This will flush the CMOS memory which stores the BIOS password and all other configuration. (See Warnings)
5.Set the battery back into place and power on the computer.
6.The computer should then warn you that the CMOS configuration could not be found. You can either reconfigure it yourself or restore defaults. Restoring the default configuration should be fine. 
7.You will notice that the BIOS password has been cleared and you can boot without it. You may reset the BIOS password to something else by going into the BIOS configuration and setting a new User Password.
