17. BIOS FlashBack™ LED
The FlashBack™ LED lights up or blinks to indicate the status of the BIOS
FlashBack™.
18. Q-LEDs
The Q-LEDs check key components (CPU, DRAM, VGA, and booting devices) during
the motherboard booting process. If an error is found, the critical component's LED
stays lit up until the problem is solved.
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.
