1.9 Onboard LEDs
1. Standby Power LED
The motherboard comes with a standby power LED that lights up to indicate that the
system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should
shut down the system and unplug the power cable before removing or plugging in any
motherboard component. The illustration below shows the location of the onboard LED.
2. POST State LEDs
The POST State LEDs provide the status of the following key components during
POST (Power-On-Self-Tests): CPU, memory modules, VGA card, and hard disk drives.
If an error is detected on any of these components, the corresponding LED will stay lit
until the problem is resolved.
