The Windows power management system is based upon an idle timer. If the computer is idle for longer than the pre-set time, then the PC may be configured to sleep or ' hibernate '. Windows uses a combination of user activity and CPU activity to determine when the computer is idle.
The power management for microprocessors can be done over the whole processor, or in specific components, such as cache memory and main memory. With dynamic voltage scaling and dynamic frequency scaling, the CPU core voltage, clock rate, or both, can be altered to decrease power consumption at the price of potentially lower performance. This is ...
Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring. It was first released in ...
A second control offered a target of either "economy" or "performance". Some versions offered a third control that adjusted the processor based on power rather than speed. [2] LongRun was based primarily on reducing the clock frequency and voltage supplied to the processor, now commonly called DVFS. Lower frequency reduces performance but also ...
Processor manufacturers usually release two power consumption numbers for a CPU: typical thermal power, which is measured under normal load (for instance, AMD's average CPU power) maximum thermal power, which is measured under a worst-case load; For example, the Pentium 4 2.8 GHz has a 68.4 W typical thermal power and 85 W maximum thermal power.

AMD PowerNow! is AMD's dynamic frequency scaling and power saving technology for laptop processors. The CPU's clock speed and VCore are automatically decreased when the computer is under low load or idle, to save battery power, reduce heat and noise.
