Had the same problem. After going through the agony of Dell support the motherboard had to be replaced. Which then turned to be a bigger nightmare where the laptop heated up. Mother board had to be replaced again. Now Im having montor issues. the 7390 seems to have everything on the motherboard which seems to be a very fragile peice of equipment. they are going to take you for a ride. Good luck
