My laptop fell from a small coffee table and landed on its back. The blue power button was still on so I thought it was okay but it wouldn't start up. I pressed down the power button to restart it but the screen still didn't come on. The battery is embedded in it so I couldn't take it out, I waited for the battery to die and switched it on but the screen still didn't come on. I honestly don't know what to do. I have a lot of files on this computer that I need. Please help.
