Turn off your notebook LCD with one-click

There are times when you just want to listen to some music on your notebook/laptop and want the display(LCD) of your notebook to remain off while Clicking this icon from your desktop will turn your LCD off. Its that simple! the lid is still open, while there are small amount of notebook manufacturer’s who provide this simple option of turning off the notebook’s LCD when not in use but many dont. I own a HP DV2799 Special Edition notebook (see my review here), while its a great notebook in almost every way it still lacks a basic button to switch off the display(LCD) whenever I want to and not only this notebook but also many new & expensive notebooks lacks this option.

This led to me developing my very own small application which turns off my notebook LCD just with one click. I wrote this application in C# using Microsoft Visual Studio 2008. Its basically a simple console based application that makes use of a dll(User32.dll) file from Windows using System.Runtime.InteropServices namespace and then calls the required function.
