    I have my maximum processor state set to 10% on battery. To test this I launched Counter-Strike Source and in my task manager it would go up above 10% cpu usage. Does this mean that it using more than 10% of my cpu? I am confused.

    I have a sager NP5797 with the q9000

    Which version of Windows are you using, and did you edit the correct plan for when you are on battery power?

    and what tool were you using to look at cpu utilization?

    I'll just give and example of what Maximum Processor State means.

    For a Core 2 Duo 2GHz
    Max processor state = 50% means the processor (using speedstep) will be allowed to run at up to 1GHz. CPU utilisation should be higher because there is less CPU to share around with the same amount of programs running.

    If you set the percentage to 50%, and you don't see the CPU frequency drop to 50% (or you don't see the speed drop to half of the maximum speed), then something isn't working correctly. Correct?

    I suppose so. For my P8600 (2.4 GHz), at 50% it gets locked to 800MHz, because I've only seen the speeds, 800MHz, 1.6GHz and 2.4GHz on my processor.

    Would this change my clock speed or the percent of cpu utilization?

    As namaiki stated, CPU usage is not the same thing as CPU frequency. A processor will be utilized more if the clock speed is lower. Since a processor generates less heat when the frequency is lower, it takes less power to cool it, hence the power savings gained.

    If you use a tool like RMClock, you can have better control (IMHO) of your processors.
