Product Description

Table 15 lists the system states based on how long the power switch is pressed, depending on how

ACPI is configured with an ACPI-aware operating system.

1.13.1.1

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.

Table 16 lists the power states supported by the Desktop Boards D865GBF and D865GLC along

with the associated system power targets.

See the ACPI specification for a complete description of

the various system and power states.
