You have major problem here - the power regulator on the motherboard which regulates the line voltage down to 12V to feed the inverter, and battery voltage /up/ to 12V to do the same, is blown. I've seen this happen in HP laptops - line voltage to the inverter on mains power reads at 18.2-18.5V (which overloads the inverter), on battery it reads 10.5-11 (which won't fire the inverter). This is usually a sign of a bigger problem. Usually one that involves replacing the motherboard.
