Intel Desktop Board DP55SB Technical Product Specification
1.14.1.1
30
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 6 lists the power states supported by the board along with the associated
system power targets. See the ACPI specification for a complete description of the
various system and power states.
