I have been plagued with problems regarding the track pad (not registering clicks) and have tried the tightening screw method to improve responsiveness, but the problem would come back shortly after.
Today I tried a new technique. Remove the screw completely (tiny screw-disk) and between the actual trackpad and the screw, put a small piece of paper. So basically all I did was cut a tiny, tiny rectangle out of paper, folded it in half to make a square, then cut down to size to fit the hole. I then placed the screw back in and tightened until it was perfect for me.
So it clicks like a dream, no problems, and I am noticing that the click is less noisy than before. Just my experiences.
