Abstract
Embodiments of the present invention are directed at identifying an idle state for a processor that minimizes power consumption. In accordance with one embodiment, a method for identifying a target idle state that does not require a linear progression into any intermediate states is provided. More specifically the method includes collecting data from a plurality of data sources that describes activities occurring on the computer and/or attributes of the hardware platform. Then, using the collected data, a target idle state for the processor is calculated. Finally, if the current idle state of the processor is different than the target idle state, the method causes the idle state of the processor to be changed to the target idle state.
