Typical settings and their explanation is provided below:
Home/Office Desk : This scheme is suited to most home or desktop computers that are left plugged in all the time.
Portable/Laptop : This scheme is designed for extended battery life for portable computers on the road.
Presentation : This scheme keeps the monitor on for doing presentations.
Always On : This scheme keeps the computer running so that it can be accessed from the network. Use this scheme if you do not have network wakeup hardware.
Minimal Power Management : This scheme keeps the computer on and optimizes it for high performance.
Max Battery : This scheme is extremely aggressive for saving power.
What these do not talk about is the CPU "Throttle Mode" of the processor under each scheme. The various throttle modes are:
None:-- Always runs at the highest performance - maximum frequency
Adaptive:-- CPU frequency depends on the demand - can vary from minimum to maximum.
Constant:-- Always runs at the lowest performance to conserve battery
Degrade:-- Starts at lowest performance state, and then starts reducing performance further as the battery gets lower - this is used to maximize the battery life.
The CPU throttle modes used under various power schemes are:
Power scheme ---------------------- AC ---------- Battery
Home/Office Desktop --------------- None --------- Adaptive
Portable/Laptop -------------------- Adaptive ----- Adaptive
Presentation ----------------------- Adaptive ----- Degrade
Always On-------------------------- None --------- None
Minimal Power Management --------- Adaptive ----- Adaptive
Max Battery ------------------------ Adaptive ----- Degrade
With Windows XP SP2 only Max Battery will enable the AMD PowerNow! battery saving feature. See also my post here:
