I right clicked the < icon in the tray area, and selected properties.
I'm given a list of System Icons, such as Clock, Volume, Power, and Action Center.
Power and Action Center are greyed out.
For Power, fair enough, I'm running a desktop.
But Action Center should allow me to turn it on/off, but I can't as it's greyed out.
I don't believe it's because the option to enable it is disabled somewhere.
I believe it's because the Action Center functionality isn't running.
Does that help?
