Thank you for bringing this matter to the Community. I can sure help with your inquiry.
The LED will stay on waiting for a possible magic package while the unit is off, but if you disable Wake On LAN the light should stay off. Of course, if you disable this option the unit will not wake from LAN.
Thank you for the feedback.
There is no solution if you want to use ethernet normally.
Too bad we can not turn off the diode when the NUC is off. It seemed normal to me to be able to settle this.
What do you mean by "magic package"?
Can we wake up the NUC?
