Patent ID: 7603571

Claim:
An information handling system, comprising: an input power source, wherein the input power source is an alternating current power source; a power measurement module coupled to the input power source and operable to measure a set of quantifiable characteristics of the input power source; a power evaluation module operable to receive a measurement signal from the power measurement module; a power supply coupled to the power measurement module and operable to provide a power level indicator signal to the power evaluation module; a plurality of system components, wherein the plurality of system components includes at least one processor; a system regulator coupled to the power supply and providing to the power evaluation module a measurement signal related to power being consumed by the plurality of system components; wherein the power evaluation module evaluates a power source condition of the input power source on the basis of the measurement signal from the power measurement module and the power level indicator signal from the power supply; and wherein the power evaluation module is operable to issue a throttle command to the processor to place the processor in a reduced power mode if the power source condition of the input power source is sufficiently substandard.
