Q LEDs (BOOT_LED, VGA_LED, DRAM_LED, CPU_LED)
Q LEDs check 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.
