Unfortunately I had to return my laptop.  I was thoroughly pleased with it when I first got it, but a couple of weeks ago, when I would start it up, it would say "extremely low battery" and then shut down even thought the battery was fully charged.  I would start it up again and it would work fine until this week.  This week, after restarting it and using it for several minutes, it would shut down again.  That's when I felt like I had better send it back before it got even worse.
