I recently installed Ubuntu 14.04 and the battery icon keeps disappearing. It will show up when I plug the charger in, but when I restart my laptop it disappears. If I plug the charger in and then unplug the charger the icon will show up, but when I restart the computer again it will disappear again. I am a first time Ubuntu user and Linux user. I have tried Google and it has led to no solution. Any help would be awesome.
