I want break our vaio vgn-sz440 bios password.i forget it


BIOS password can only reset by changing Jumper settings on the Motherboard. For this you need to open your notebook. You have to be very cautious while doing this, if you are not comfortable doing this, take your notebook to a nearest Computer repair shop. You can refer videos on Youtube to achieve this as there is no other way aroud to reset BIOS password.
