How to Restore the BIOS for a Compaq Presario V6000

Written by sara bailey | 13/05/2017

The Compaq Presario V6000 is a laptop computer that was released in 2006. As with every personal computer, the V6000 has a BIOS (basic input/output settings) chip installed on the motherboard that saves computer settings even when the computer itself loses power. If the BIOS settings become corrupt, the computer will not function correctly. Recovering the BIOS entails taking the computer apart, and resetting it directly from the motherboard.

Hold the "Power" button on the Compaq Presario V6000 notebook computer until it completely shuts off. Pull the power cable out of the side of the computer.

Turn the computer over and slide the battery release tab to the left to unlock the battery. Hold the slider to the left and pull the battery out of the computer.

Remove the three screws that hold the RAM cover onto the underside of the computer. The RAM cover is located in the middle of the underside of the computer. Pull the cover off and you will see a small, black battery. This is the CMOS battery that provides power to the BIOS chip.

Pull the circular battery out of the motherboard, and leave the battery out of the computer for at least 30 minutes.

Press and release the power button while the CMOS battery is still out of the motherboard. Then place the CMOS battery back into the motherboard.

Place the RAM cover back onto the computer and tighten the three screws holding it in place. Slide the laptop battery back in and reconnect the power cable to the computer.

Turn the Compaq back on and the BIOS will be reset and recovered.
