I put a CD in the drive for a children's art program. The computer went black and now the on/off switch blinks 5 times. I did the hold the switch schtick, 30, 60, 120 seconds and nothing. With the battery in/out. The power does not even come on with the battery out as I believe the battery has to be in for the plug to work. This laptop is less than 2 years old. I suspect it is the motherboard and, if so, it is probably not worth repairing. Would that be an accurate assessment?
