I just got my 4750 and it used it for about an hour and half to drain the battery then it shut off when the battery died. So i proceeded to plug in the ac adapter and then it keep starting and restart with some errors i believe they might have been some fatal errors. so then i unplugged it from the wall and it works fine off the battary. is it possible the adapter is deffective? whats wrong please help i waited all damn week for this and now it is busted.
