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 in any 

motherboard component. The illustration below shows the location of the onboard LED.

DRAM LED
DRAM LED checks the DRAM in sequence during motherboard booting process. 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.
