So my laptop is an HP G7,and the other night I was using it just fine (Monday 9/9/13) and I went to go use it last night, 9/10/13. When I turned it on, it turned on and the light next to the power button was on. However, my screen never came on. I tried plugging it into my TV with my HDMI cable and nothing came on the TV. Any ideas as to what it could be?
