1.2.7 Onboard LEDs
1. Hard Disk LED (HD_LED)
The Hard Disk LED is designed to indicate the hard disk activity. It blinks when data
is being written into or read from the hard disk drive. The LED does not light up when
there is no hard disk drive connected to the motherboard or when the hard disk drive
does not function.
2. Q LEDs (BOOT_DEVICE_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 ashes until the problem is solved. This user-friendly design provides an intuitive
way to locate the root problem within seconds.
