If users can not access the laptop after it has been turned on, meaning the use of laptops should pass the BIOS password. BIOS passwords are stored in CMOS memory which resources are maintained by a small battery when the PC is turned off, attached to a particular place or attached to the motherboard. If a user opens this battery, all CMOS information (including the BIOS password) will be lost. Users must re-enter the correct CMOS setup information to use laptops.

If this happens, usually there is another alternative that is at a place on the motherboard there is a jumper that will clear the BIOS password. If you have documentation of your laptop motherboard, then the bias easily locate this jumper. If not, the jumper may be labeled on the motherboard.
