System States and Power States
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.
