Fixing Macbook glasstrackpad... Part 1

As I promise, this is a SAVE for you. How annoying is being without a good trackpad on your macbook white,aluminium,pro,air... Now I will save you from buy a external mouse :)
This is the area what we are goin to work (the small button inside red circle). Its VERY easy to do. I already took out screws from trackpad. The image is a macbook aluminium, for other models are the same, just took out battery and you will find the same image.

If you find problems to tear up, just ask me. Im glad to help!
