Power Management

Power management is implemented at several levels, including:

Software support through Advanced Configuration and Power Interface (ACPI)

Hardware support:

oPower connector o Fan connectors

o LAN wake capabilities

o Instantly Available PC technology o Resume on Ring

o Wake from USB

o Wake from PS/2 devices

o Power Management Event signal (PME#) wake-up support

ACPI

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 VIG390S motherboard requires an operating system that provides full ACPI support. ACPI features include:

Plug and Play (including bus and device enumeration)

Power management control of individual devices, add-in boards (some add-in boards may require an ACPI-aware driver), video displays, and hard disk drives

Methods for achieving less than 15-watt system operation in the power- on/standby sleeping state

A Soft-off feature that enables the operating system to power-off the computer

Support for multiple wake-up events

Support for a front panel power and sleep mode switch

Table 9 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.
