Abstract
A computer system has multiple performance states. The computer system periodically determines if the software power state maintained by power management software that represents the power state of the processor or other computer system component matches the actual power state of the processor or other computer system component. If not, the actual power state and the software power state are resynchronized, for example, by reinitializing the power management software or otherwise causing the software power state to match the hardware power state.
