4. Power LED
The motherboard comes with a power-on button 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
power-on button.
3. Q LED
Q LEDs check key components (CPU, DRAM, VGA card, and booting devices)
in sequence during the motherboard booting process. If an error is found , the
corresponding LED will continue lighting until the problem is solved. This user-friendly
design provides an intuitive way to locate the root problem within seconds.
