The simplest way to remove a BIOS password is to simply remove the 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.
Anyway, open up the computer case using a screw driver and locate the flat, circular and metallic CMOS battery. It should look something like this : http://pctechnotes.com/wp-content/uploads/2009/09/remove-battery.jpg
Some computers have this part standing upright. Once you have located it, observe how the latches are holding it.
Make sure to power down the computer, unplug the power cables and unplug any USB devices if they are powered. The computer must not be able to get power from anywhere for this to work. Take out the CMOS battery and wait 10 - 25 minutes before putting it back in.
Plug everything back in, power up the computer and enter the BIOS again. If everything went well there should be no more password. In some cases, if you get weird error messages during bootup now, you will need to goto "Load BIOS Defaults" in BIOS and save the changes to fix them.
