Test Case:     React on AC add/remove events
Categories:    Desktop, KDE, AC
Requirements:  KDE Installation, a Laptop (and an AC adaptor) 
Depends On:    Test Case 

Action:
============================
Start KDE as normal user, check if KPowersave is running (check for the 
KPowersave icon in the taskbar, or "ps aux | grep KPowersave").

Start on a console: 'lshal -m'.

Click on the KPowersave icon in the task bar with the left mouse button. 
The information dialog of KPowersave should show up containing general 
(on the top), battery (in the middle) and CPU information (bottom).

Remove/add the AC plug from the machine and monitor the dialog and the 
applet icon in the task bar

Expected Results:
============================
1) If you remove the AC plug the applet icon in the task bar should 
change from an icon with a AC/power plug to an icon with a battery. If 
you add the AC plug the otherwise should happen.

2) If you remove the AC plug the dialog should change some parts:
2.1) Miscellaneous section:
     - the 'Current scheme' should change from Performance to Powersave
     - the icon in this section (in the top left corner) should change 
       from a plug to a battery icon
2.2) Battery state section:
- the icon in this section (in the top left corner) should change to the 
  same as the applet icon
- the 'AC Adapter' LED (on the bottom of the section) should switch from 
  green (on) to dark green (off) and the text right of the LED should 
  change from 'plugged in' to 'unplugged'
- (after a while or immediately) a new text should be shown above the AC 
  LED: 'Power Consumtion' and a text with  the current consumtion.

3.) If you (re)add the AC Plug the dialog should change this:
3.1) The current scheme should switch back to Performance (incl. the icon), 
the icon should switch back to an icon with a plug, the AC Adapter LED should 
get green again, the 'Power consumption' info get may removed (after a while,
depends on battery state)
