no1 told you how to put it in yet:

power your computer off @ the back, remove the side, look @ where your screen is plugged in then unplug everything that was plugged into the same metal strip, undo any screws or clips then @ the base there's a small plastic  clippy thing push it down then put your new one in its place..

nb: just make sure the one you get is the same interface as the one you have
