Abstract: An information handling system includes a battery and a charger. The battery provides a battery voltage to a main power rail of the information handling system and is couplable to the main power rail through a switch. The charger has an output coupled to the main power rail and an input coupled to an external power adapter. The power adapter provides a selectable voltage level to the input. The information handling system selects a particular voltage level that is lower than the battery voltage and directs the switch to decouple the battery from the main power rail when the information handling system is in a soft power-off state.
