1.8 Onboard LEDs

1. Standby Power LED

The motherboard comes with a standby power LED that lights 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 any

motherboard components. The illustration below shows the location of the onboard

LED.

2. POST State LEDs

The POST State LEDs provide the status of these key components during POST

(Power-On-Self Test): CPU, memory modules, VGA card, and hard disk drives. If an

error is found, the critical component’s LED stays lit up until the problem is solved.
