Hey guys I have a laptop Dell Latitude D630 and it's a friends for his daughter and he gave it to me to look at because when you turn it on all you see is the back light and thats it no screen the operating system is Ubuntu 12.04 but that won't be the issue I google this problem and it seem to me that it could be the video chip I saw a video on youtube and he had the same issue and thats a big tear down any question to what it may be
