I was just scrolling through my files on my LENOVO G40-80 laptop then suddenly the screen went black. It was still on, it has power and I was charging it that time. After a few reboots, I discovered that it wasnt black, I can see the icons and the screen only when I turn directly point out my phone's flashlight on the screen. But without the flashlight i dont see anything. Everything is normal just that i cant see my screen without me using the flashlight. Please help me i have a lot of paperworks to do
