Turning Macbook on with non-functionable Power Button

So I believe I got a very small amount of water on the keyboard and to my surprise my Macbook's Power button and keyboard no longer works. Not thinking I made a mistake and turned the notebook off with the trackpad (as it still worked/works) and didn't think about the possibility that I won't be able to turn my Macbook on anymore. Any suggestions as to what to do? When the keyboard wasn't working everything else was completely fine. Thanks!
