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.
