Remove the AC adapter, (Charger), and Battery.

Press the Power On button, and hold it down for a count of 10 seconds.

Let go.

Do this procedure two more times.

This will clear CMOS Error Codes, and set the BIOS Setup back to the factory default settings; as it came from the factory.

This will not however, clear a BIOS password, or a Windows password........
