Intel Desktop Board D945GCLF2 Product Guide Power Management Features Power management is implemented at several levels, including: • Advanced Configuration and Power Interface (ACPI) • Hardware support: ― Power connectors ― Fan headers ― +5 V standby power indicator LED ― LAN Wake capabilities ― Wake from USB ― Wake from PS/2 keyboard/mouse ― PME# 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 Power Connectors The Desktop Board has two power connectors. See Figure 13 on page 34 for the location of the power connectors. Fan Headers The Desktop Board has a 3-pin MCH fan header and a 3-pin chassis fan header. See Figure 12 on page 33 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 4, 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. 18
