1.11 Power Management
1.11.1
Power management is implemented at several levels, including:
•
•
ACPI gives the operating system direct control over the power management and Plug
and Play functions of a computer. The use of ACPI with the board requires an
operating system that provides full ACPI support. ACPI features include:
•
•
•
•
•
•
Table 6 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.
