1. A computer system capable of operation in different power consumption modes, the computer system operating in a normal power consumption mode when the computer system is subject to a normal level of activity and operating in a reduced power consumption mode when the computer system is subject to a reduced level of activity, comprising:

  • a processor;

    a mass storage device coupled to the processor; and

    a power management circuit coupled to the processor, the power management circuit adapted to reduce the power consumption of the computer system responsive to a rate of processor events being below a predetermined low event threshold and adapted to increase power consumption of the computer system responsive to the rate of processor events and being above a predetermined high event threshold, the power management circuit determining the rate of processor events based on processor signals.
