Power Management Features

Power management is implemented at several levels, including:

Advanced Configuration and Power Interface (ACPI)

Hardware support:

Fan header

+5 V standby power indicator LED

LAN Wake capabilities

Instantly Available PC technology

Wake from USB

Wake from PS/2 keyboard/mouse

PME# wakeup support

WAKE# signal wakeup 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 Desktop Board requires an operating system that provides full ACPI support.

Hardware Support

Fan Header

The Desktop Board has a 3-pin chassis fan header. See Figure 15 on page 46 for the location of the chassis fan header.

+5 V Standby Power Indicator LED

CAUTION

If the AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices.

The Desktop Board’s standby power indicator, shown in Figure 3, is lit when there is standby power to the system. This includes the DIMM socket and the PCI bus connector, even though the computer appears to be off.
