Description of problem:
The properties of the battery do not get updated when the battery is being charged.

Version-Release number of selected component (if applicable):


How reproducible:
Every time.

Steps to Reproduce:
1. On a battery powered laptop
2. Unplug power cable
3. Select battery properties from context menu
4. Watch for changes in the values
  
Actual results:
Values do not change

Expected results:
Values should change

Additional info:
The notification for 'you are not on battery power' does remove the properties
page, but without bug #228189 the 'fully charged' notification doesn't occour.  

Updates while charging/discharging is however what I want to see (but not
polling excessivly, that would be pointless and just chew power).
