Have you forgotten your bios or cmos password? Or are you looking for hacking them. Its easy if you have a screw driver!!
First, a question,why dont computer forget the bios password,or time,date even if we keep it unplugged for a long time.
Yeah,it has got some power back up,or a battery inside it. Have you noticed a small coin sized battery on the mother board of your computer.
Remove it,rub it and after sometime,keep it back!
You’re done! Now start happy computing!!
The Bios password is stored in CMOS memory that is maintained by the battery in the motherboard. So we attack the battery !
