The motherboard comes with two standby power LEDs that light up to
indicate that the system is ON, in sleep mode or in soft-off mode. This is a
reminder that you should shut down the system and unplug the power cable
before removing or plugging in any motherboard component. The illustration
below shows the location of the onboard LEDs.
