Screen flickering of my laptop

@anjugarg you are not giving us enough information. When you say your laptop is not working, what do you mean by that. It is not working or just not showing a proper display. If your screen is flickering, your laptop may still work, but your display may not. Could be because of a bad LCD or a bad display cable. You really need to give us more information and also let us know what you have tried to fix this.

First thing you want to do, is to connect an external monitor and see what that displays. If that works, you know it is either your LCD or the display cable that is not working.
