Diagnostic LEDs

Hardware Troubleshooting at a Glance
Onboard LEDs controlled by the system BIOS
indicate if a malfunction is occurring, allowing

users to quickly diagnose which major
component (CPU/DDR/VGA/HDD) is
malfunctioning so they may take action
promptly.

The status LEDs show whether the CPU,
graphics card, memory, and operating
system are working properly after system

power-on. If the CPU/VGA/DRAM LED is on,
that means the corresponding device is not
working normally; if the BOOT LED is on,
that means you haven't entered the
operating system yet.
