Can't figure it out. Of course it happens while on the way home from work after not using it all day. Sometimes needs to wait until she get's home to plug it in to get it to power up. You would assume maybe dead battery but as soon as she plugs it in and then it comes on it shows 80+% battery. Any ideas?
