2.2.6 Onboard LEDs
1. Standby Power LED
The Standby Power LED will light up once the system is connected to a power source.
2. Q-LEDs
These ID LEDs of CPU, DRAM, VGA card, and HDD indicate key component status
during POST (Power-on Self Test), providing an elegant embellishment to the
motherboard design. The LED lights will ash sequentially during system bootup. 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.
