1.13.1.1
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.
Table 10 lists the power states supported by the Desktop Board D865PERL along with the
associated system power targets. See the ACPI specification for a complete description of the
various system and power states.
