This might be a little hard to explain, but will be easier if you have an MBP to do this exercise. My touchpad/trackpad, is fine, except for that when tapped in the lower left quadrant (where you normally click) it makes a click noise (from the pad itself) tapping anywhere else yields no sound. I pushed hard on the pad, and kinda pressured it in every which way, and every time I do, the clicking stops for about a minute or so. What can I do? take it in? live with it?
