Introduction of the BIOS
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.
