1.12 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 in any
motherboard component. The illustration below shows the location of the onboard LED.
2. 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.
