My relatively new Lenovo T60 laptop will boot and initial screens (windows loading and lenovo screen) will show, but when the system finally loads the screen goes dark. I know that the computer is on (windows music plays) but the screen does not load. The laptop was fine yesterday. The only thing I can think of is that perhaps one of the cables got loose? (I had the laptop in my car in its case and perhaps it was jostled). Any and all suggestions would be greatly appreciated!
