This is an old 17 inch HP DV7 1299eb; Very good system but a little wobbling of the lid/screen makes it go blank; You can restore it by closing the lid and very quickly opening it again to > 90 degrees; helps most of the time but very annoying problem. Also very strange. What could be the cause and has anyone else encountered this ?
I hope someone could refer me to a solution or to find out the cause of this. Is there any test I can do ?
