If you don't mind physically opening the laptop, you open it and take out the CMOS battery, boot it up without it then shut it down and put the CMOS battery back in and boot. The BIOS password will no longer bet set. I don't know if this still works but it used to on older laptops.
- oneplane 7y agoDoesn't work anymore. The data is no longer stored in CMOS.
- AstralStorm 7y agoSometimes it is the same chip but not the same range, so it's not cleared ever.

- zaarn 7y agoModern UEFI uses Flash Storage and CMOS is only relevant for the computer time keeping (though some UEFIs have a full CMOS to emulate BIOS behaviour)
