1.1.8 Onboard LEDs
1. Q LED (CPU, DRAM, VGA, BOOT)
Q LED checks key components (CPU, DRAM, VGA card, and booting devices) in
sequence during motherboard booting process. If an error is found, the corresponding
LED remains lit until the problem is solved. This user-friendly design provides an
intuitive way to locate the root problem within seconds.
The Q LEDs provide the most probable cause of an error code as a starting point for
troubleshooting. The actual cause may vary from case to case.
2. USB BIOS Flashback LED (FLBK_LED)
The BIOS Flashback LED flashes when you press the BIOS Flashback button for BIOS
update.
