Unresponsive Trackpad Button
15 - 30 minuten
Perhaps because of time, the button on my Macbook Pro's trackpad beame unresponsive, although the trackpad's multitouch functions were working correctly. I know almost everything you do with the button can be done with multitouch gestures, however for those few things you really need it, like dragging files from a window to another through exposé, I felt the need to fix it.
Everyrthing went well until I reached the screws that holds the trackpad in place. In one side I could remove them without effort, however on the other side the screws were so tight that when I tried to remove them I actually damaged the screws making it almost impossible to remove them. Fortunately iFixit provided a replacement for the 4 screws an the metal strip that hold each side of the trackpad, because the solution I found to be able to remove the trackpad, was to remove the other 2 screws tha hold the strip to the aluminum body and cut it with a metal cutter. Then I replaced the strip and the screws and installed the new trackpad which worked flawlessly.
For iFixit I recomend to include a solution to the problem I experimented just as an addon to the simpler instructions for people that like me run into that kind of scenario. And for the ones that are thinking about changing their trackpad be sure to center it the best you can but leave a little more space to the bottom part(where the actual button is) before thightening the screws, because since this part is the one that moves the most when clicking if it is too near the macbook's aluminum body it can get stuck.
