On this system, the airplane mode indicator is always on. fn+f2 does nothing.
The light under the key stays on.

Similar posts have been found. but, related to 12.04, not 16.04. And, no solutions were offered anyway.
I suspect that this may be related to another problem with always running hot and on "battery" when AC is attached. But, honestly, I am completely lost.
Any help would be appreciated.
Thank you.

You might see if the F2 light, an LED actually, performs correctly after this:
Reboot and test.
