Black screen problem

[Moiz Khan97]

Hey! Once a month back my laptop fell from my lap on the floor. But afterwards it was working properly. a week ago when i switched on the screen appeared black though the laptop was working and the fan was running. I tried it with monitor but monitor's screen too appeared black. What's the reason? My laptop is lenovo B570e.

CPU may have been loosened from its socket. Display connector could have been knocked loose from the motherboard or display panel... Chipset could be damaged. The list goes on.

Without more information on the problem, I can't tell you exactly what's causing it.

How long ago did you buy this and did it come with a warranty?
