[Bug 860427] Re: Oneiric displays 'Laptop battery critically low' message after AC is unplugged when 'charged' shown on battery indicator

 

I have the same issue on Dell Mini 9 with ubuntu 11.10 i386.  When removing the power cable, I usually get a dialog saying the battery is critically low and the laptop powers down 30 seconds later.  Occasionally it does not happen (says 99% charged) and once it bizarrely said 96% but only 6 minutes left!  So maybe the time left is being misreported.
 
In addition, when charging or fully charged the battery icon usually does not show the mains power type icon, it shows the battery type icon.

This did not happen in ubuntu 11.04.
