[Solved]Ubuntu 11.10 battery indicator missing

If you are using ubuntu 11.xx version , you might be wondered why the battery indicator icon is missing. a number of users reported this missing of battery icon and here is the solution for the problem.
Problem
The Above bug, or the absence of battery indicator on the upper panel is a commonly found issue with ubuntu 11.10 installations. cause of this issue is different machine to machine
Solutions
There are a handful of ways to solve the battery indicator problem. and my solutions are listed below

1.  Purge and re-install indicator-power
     
    sudo apt-get purge indicator-power

     sudo apt-get install indicator-power


2. Change theme to  'Radiance'.or change away from Radiance,
    to  Make sure this is not an icon issue.

3.  Remove revenants from Unity if any,




  1. (get settings, for curiosity's sake)
    gsettings get com.canonical.Unity.Panel systray-whitelist
    
    (should look something like:)
    ['JavaEmbeddedFrame', 'Wine', 'scp=-dbus-service', 'Update-notifier']
    
    (clear whitelist)
    gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"
  4. Try an alternative battery monitor package
