There is a jumper on all motherboards that you can use to clear CMOS. Next to this jumper is usually the phrase Clr CMOS.
All you have to do is remove the jumper from pins 1 and 2 and move it to pins 3 and 4 and return it to its original position after a few seconds. The CMOS settings will be reset and the BIOS password will be removed.
2) Removing the battery:
You can remove and replace the battery of your device on the motherboard, in which case all CMOS data will return to the default state. But note that it is a little difficult to replace the battery.
3) Change IC (Cheap CMOS):
If none of the above methods work, you can replace the CMOS IC with an IC of the same type. Or reschedule it. This requires special tools and can be done by qualified technicians.
