Not to alarm you, but in my experience, the repeated malfunction of one component usually is a sign that another component isn't functioning correctly. Rather you *could* have an issue with the components that manage, monitor your battery, ect, even certain software could be at fault. I don't really have any recommendations on what to do, because it can be hard to communicate a problem like this to any sort of customer support representative. As for anything you can do yourself, it depends on your comfort and confidence with technology, the problem solving process(Process of elimination), ability to find answers for yourself as this could be a problem very unique to you, or a problem several people have had. The only advice I can offer is to keep searching for similar experiences and gain some insight into the problem a bit. If anything you'll come out of the experience a little enlightened?
^^' sorry if that sounds kinda lame, and I don't mean to scare either.
