How to Unlock a Password on a BIOS Intel Motherboard

The basic information about the hardware in any computer is stored in a chip known as the BIOS, or Basic Input Output System chip. It is a volatile memory chip that will lose the information after a short amount of time if there is not a source of power to keep it intact. A small battery on the motherboard keeps the information in the BIOS when the power is off. This battery can be removed to erase the BIOS information, including any passwords stored inside. Two ways are available to perform this operation.
