2.9 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. 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.
You may disable the DRAM LED in BIOS. Refer to section 3.9 Tools menu for details.
