Hi saibaba, welcome to our site! :)
In terms of your laptop screen problem, we don't work on technical problems in this particular forum; it's just a place for new members to say "Hi" and introduce themselves.
If you'd like our help, what you should do is start a new thread in our Monitors, Displays, and Video Cards forum and we'll take it from there. In that post, please try to give us as much specific information about the problem as possible. Info such as the make and model of the laptop, some history on when the problem started, etc. will help us get to bottom of the problem most quickly.
