+5 V Standby Power Indicator
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 (green LED), shown in Figure 3, is lit
when there is standby power still present on the board even when the computer
appears to be off. For example, when this indicator is lit, standby power is still
present at the memory module sockets and the PCI bus connectors.

ACPI S1, S3, S4, or S5 state.
WAKE# Signal Wake-up Support
