Trackpad suddenly stops working

Sometimes after my Macbook Pro goes to sleep, the trackpad will no longer work. It won't even make the clicking action when pressed down. Since I cannot figure out how to make it work again, I am forced to hold down the power button to turn off the computer (which I'm guessing is not good for it). When I turn it back on, trackpad works as though there were never an issue.
