I have Vista Home Premium 32-bit. The computer manufacturer says that keeping my laptop plugged in after it is fully charged will ruin my battery, so I unplug & run on the battery once it is fully charged. My problem is that the only warning I get that the battery is low is a teeny-tiny yellow flag next to the power options icon in the notification area at the bottom right of the screen. This is very easy to miss. I am tired of my computer shutting down while I am in the middle of something. Is there a way I can get a pop-up warning that my computer is going to shut down? I am a novice, so please go light on the tech terms. Thanks.
