Find the service tag on the computer and plug it into this link:

That should get you on the right track. The one you have linked to looks very expensive to me.

You could also just pull yours out (take a picture 1st if you are tentative about the connections) and go to your local computer store. They probably have replacement power supplies on the shelf.

Good luck!
