If ur friend put a BIOS(Basic Input output System) password or at home ur father has put Password for you can't access Computer, so its important that you have to Break it if u wan tto accesss the Computer. This are the Steps to follow.
1. Open the CPU. (Make sure that the power Supply is off.)
2. In mother Board u can see a Battery (Silver Colour) called CMOS battery. Just Remove it for 120-150 Seconds.
3. Now put that battery as it was. And Start the computer it will not ask you for Password. It's Done.
Hope U like this.
