+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 still present on the board even when the computer appears to be off.
For example, when this green LED is lit, standby power is still present at the memory
module sockets and the PCI Express connector.
