Software Support through ACPI

The Advance Configuration and Power Interface (ACPI)–aware operating system can place the system into a state where the hard drives spin down, the system fans stop, and all processing is halted. In this state, the power supply is still on and the processors still dissipate some power, so the power supply fan and processor fans are still running.

Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state.
