What is this orange LED? Motherboard manual does not have any info.

[dumplinknet]

Asus ROG Strix Z370-i motherboard in a Skyreach 4 Mini.

This orange LED (indicated by the arrow) is lit and I have no clue what it means. The manual does not even note that it exists.
It sits right below the USB 3.1 connector.

Your help is appreciated!
Thanks!

Nothing to worry about. It is the Standby Power LED. Asus Z270-i motherboard has the same LED.
See Asus' official response in post #3 of the thread below.
