Abstract: An AC-to-DC power adapter provides DC power to an information handling system at a first higher DC voltage or a second lower DC voltage based upon a power state of the information handling system. For example, approximately 19 Volts DC power is provided if the information handling system is in an on state or if the information handling system is charging a battery. Approximately 13 Volts DC power is provided if the information handling system is in a reduced power state, such as an ACPI S3 state, with a battery having a substantially full charge.

Abstract: A power manager of an information handling system selectively commands a first or second source voltage from an AC-to-DC adapter based upon power consumption of the information handling system. A lower direct current voltage is provided during reduced power consumption so that DC-to-DC conversion in a power supply is more efficient. A higher direct current voltage is provided during increased power consumption so that the current required to provide the increased power remains below a threshold current, thus allowing the power system to have components that operate at lower current levels under high power consumption operations yet with increased efficiency during low power consumption operations.
