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. POST State LEDs
POST State LEDs check key components (CPU, DRAM, VGA card, and HDD) 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 POST State LEDs in BIOS. Refer to section 3.8.2 Boot Settings
Configuration for details.
