Battery Indicator Missing [duplicate]

I found that my power indicator had simply crashed. Executing the following in a terminal restarted it in no time:

/usr/lib/x86_64-linux-gnu/indicator-power/indicator-power-service &disown

the indicator is:

indicator-power

Make sure that is installed.

sudo apt-get install indicator-power

If it is installed I would try re-installing it.

sudo apt-get purge indicator-power
sudo apt-get install indicator-power

I have not found an indicator file to edit that controls them loading or not.

I was having the same problem on 12.04 ... No power indicator applet (upon login -- saw one AT the login screen).

Running gsettings list-recursively|grep settings-daemon spat out that:

org.gnome.settings-daemon.plugins.power active false

In terminal,

gsettings set org.gnome.settings-daemon.plugins.power active true

... logged out and back in and I was good.

This was a fresh install from ISO of 12.04, so for those of you seeing two icons, you might want to set "....plugins.power active false" and see if one goes away.

The indicator is called: indicator-power. You can try this 3 solutions preferably by their current order:

1)

Confirm that it is installed:

sudo apt-get install indicator-power

If installed, try removing it and reinstall:

sudo apt-get purge indicator-power

sudo apt-get install indicator-power

2)

If no avail, run the configuration utility:

gnome-settings-daemon

3)

If you got here, it's time to try an alternative monitor package:
