http://ubuntuforums.org – I recently upgraded from 10.04 to 12.04 Precise (first point release) on my laptop (an MSI machine). I've resolved several minor issues but can't figure one out and have searched hear and on google to no avail (hope I didn't miss a post somewhere). Here is the problem I am facing: The battery status icon in the panel: 1.

The battery indicator does not give me a low battery warning or aler (Hardware)
