Hello. My laptop has the same problems after dropping to the floor from a bike. It was inside my backpack though. Today the screen was suddenly dark, but the power light is on. I tried to restart it many times but it didn't work. I am a student and I need my laptop every day. So I immediately sent it to the repair shop to examine the cables connect to the screen. It could be turned up suddenly. The guy unplugged and replugged two cables connected to the screen. When I take the laptop home, the screen is dark again after some time. So I tried to restart it a few times again and it didn't work. After about half an hour, I tried again and the screen is on again. I am not sure when it will be off again. Would you help me find and show me how to fix the problems please? Thank you so much.
