Bios

Depending on the model, it is usually accomplished by removing AC power and then setting a jumper or removing the battery backup.

Keep your motherboard manual handy. Locate the battery on the motherboard (looks similar to a digital watch battery, as big and flat as a one rupee coin). Press the clip located on its socket. You may use a tiny screwdriver, but never apply too much force. The battery will pop out. Short-circuit the connectors in the socket with the screwdriver. Refer to the manual and locate BIOS Reset jumper. This is normally a set of two pairs of terminals with a jumper already set on one pair. The manual will specify whether you have to remove the jumper or place it on the adjacent terminals. Do accordingly and power up the PC momentarily and then switch it off. Replace the jumper to its default position and also the battery in its socket. Boot up again.
