Abstract
A method and system for supplying power at a voltage selected from a plurality of voltages. Power is initially received at a first voltage. Embodiments communicate with an AC adapter to get device identification and see if the AC adapter supports other voltages. If so, embodiments communicate with the AC adapter to get more information about the adapter and identify what voltages the adapter is capable of providing. If one of the voltages would allow an information handling system to operate more efficiently, embodiments negotiate a power supply contract to operate at a second voltage. When the information handling system powers down, the system resets to operation at the initial voltage.
