Patent ID: 7536569

Claim:
An information handling system comprising: a chassis; plural processing components disposed in the chassis and operable to process information; a battery disposed in the chassis and operable to power the processing components; a power adapter external to the chassis and operable to interface with and power the processing components and to interface with and charge the battery, the power adapter having a predetermined power rating; and a power manger interfaced with the processing components, the battery and the power adapter, the power manger operable to detect that power drawn by the processing components approaches the power adapter power rating, the power manager further operable to manage operation of the processing components to maintain power drawn by the processing components at less than the power adapter rating; wherein the processing components have a battery optimized mode of operating, the battery optimized mode reducing power consumption of the processing components while operating on power provided by the battery, the power manager further operable to manage operation of the processing components to maintain power drawn by the processing components at less than the power adapter rating by selectively commanding the battery optimized mode.
