If you know how to remove the CMOS battery on the motherboard of your laptop this will solve your problem. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard.
Removing the battery will reset the CMOS information/data including the password.
Of course after you have done this you have to re-enter the correct CMOS info in order for your laptop to function properly.


Good day.
