2.13 Power Management

Power management is implemented at several levels, including:

 Software support through Advanced Configuration and Power Interface (ACPI)

 Hardware support:

 Power connector

 Fan header

 LAN wake capabilities

 Instantly Available PC technology

 Wake from USB

 Wake from PS/2 devices

 Wake from serial port

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

 WAKE# signal wake-up support

2.13.1 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 board 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 (see Table 9)

 Support for a front panel power and sleep mode switch

Table 7 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.

Table 7. Effects of Pressing the Power Switch

If the system is in this

state…

…and the power switch

is pressed for

…the system enters this state

Off

(ACPI G2/G5 – Soft off)

Less than four seconds

Power-on

(ACPI G0 – working state)

On

(ACPI G0 – working state)

Less than four seconds

Power-off

(ACPI G2/G5 – Soft off)

On

(ACPI G0 – working state)

More than four seconds

Fail safe power-off

(ACPI G2/G5 – Soft off)

Sleep

(ACPI G1 – sleeping state)

Less than four seconds

Wake-up

(ACPI G0 – working state)

Sleep

(ACPI G1 – sleeping state)

More than four seconds

Power-off

(ACPI G2/G5 – Soft off)
