Macbook trackpad doesnt click,a hit fixes it

[maxout5]

Hello , so today my trackpad on my white macbook doesnt want to click and i get angry easily so i decided to hit the side of it (the plastic on the left or right) and it worked again. Can you tell me how to fix this please , thanks .

Have you opened it up and inspected your battery? It might have swelled to the extent of putting pressure on your trackpad. I'm assuming you have a unibody MacBook.

This is the trackpad screw, when loosend it prevents clickyness, has happend lots of time on my MBP.
Take it to apple and have them tighten the trackpad screw.
