Onboard LEDs
1. 
Standby Power LED
The motherboard comes with a standby power LED. The green LED 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 in any motherboard component. The illustration below shows the location of 
the onboard LED.
2. 
POST State LEDs
The POST State LEDs of CPU, DRAM, VGA card, and HDD indicate key components 
status during POST (Power-on Self Test). If an error is found , the LED next to the 
error device will continue lighting until the problem is solved. This user-friendly design 
provides an intuitional way to locate the root problem within a second.
