After upgrading to Kubuntu 14.04, KDE does not notice that the laptop is running on battery!

The battery icon continues to show the 'charging' symbol. But the battery level shown in the icon keeps reducing as I use the laptop. When I hover the mouse on the icon, the tooltip displays the battery level as 50%, 40%, 19% etc.

When the battery goes down to low level (20% as defined in System settings -> Power -> Advanced Settings), there is no warning. The same is the case when the battery goes to the critical level.

How can I set this right?

  • I have exactly the same issue. I've tried different things like changing precents and adding other options. No luck. Does anyone found any solution for this bug? – user286275 May 28 '14 at 20:41

I noticed that after killing and restarting plasmashell, the battery monitor begins to function properly on my end.
