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. Core Unlocker LED
The Core Unlocker LED lights when the Core Unclocker switch is turned to Enable.
