    Inadequate answer - RTQ

    Obviously, I know how to change it - I need to know what it means.

    Carefully examining your question.

    On my Vista home premium, the minimum processor state is 0%, the maximum
    processor state is 100%. This is for both battery and plugged in.

    It basically refers to the speed of the CPU.

    For example, if the maximum is 50% while on battery, the CPU frequency will
    be running at 50% normal speed, prolonging battery life at the cost of
    performance.

    It's the minimum and maximum cpu power available.
    If you set the maximum processor state in powermanagement to 50% it should
    offer 50% of it's processing power max. when put under load.
    With this explanation I guess you understand what the minimum is for?

    Page 8 of that white paper is the start of the section on Processor
    Power Mgmt.

    Fairly easy read.

    Re: What is minimum and maximum processor state in power management

    Hello,
    I've searched about this and found this page:
    "Welcome to The Metaverse : Vista power management & CPU frequency"

    In short, Vista is able to vary the processor clock frequency (from 0 Hz to 2.4 GHz, if your maximum processor speed is 2.4 GHz) according to the processor usage. Minimum and maximum processor state control the range within which Vista varies the clock speed.

    For example, a minimum of 25% and a maximum of 75% will make Vista vary the speed between 600 MHz (25%) and 1.8 MHz (75%) for a 2.4 MHz processor. "On battery" and "plugged in" is for setting two different ranges for the charging and discharging states.

    The point of reducing clock frequency is that, the higher the frequency, the more heat the processor will produce, and the more power it will consume. The lower the frequency, the more time it will take to complete a processing (calculation).

    More detailed information with pictures can be found in the link given above.
    Hope this helps,
    ~ADTC
