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.
