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.
