Hello,
My XPS17 has a black screen on boot up. I have read other forums and have tried removing batter, holding down power for a 60 seconds and then waiting another 60 seconds followed by plugging in power cable with no battery installed. I then heard windows boot up, I heard the windows music but still a black screen. If I turn the lights off I can see what seems to be the back light on. I have some flickers here and there of a white line once in a while. After reading a few forums I think the GPU is shot. I am seeking any help and advice please. Thank you for your time.
