I have a Lenovo idea pad Y480 running Windows 7 ultimate going on 3 years old. I have had no previous problems with the system until today when I boot. I get only the backlit keypad and a black screen. I hear the HD spinning, but the only other activity I can record is that when I unplug/plug in the AC connection it beeps once. I have tried to connect it to an external monitor but it does nothing. I have tried to get into safe mode at boot but there is no response. not even a beep when I hold the f8 key down too long.
Is there something else I can check?
