It was some years (about 2 to 2.5 years?) ago that I dropped my Macbook Pro and smashed the screen. I sent it in for repairs at a third-party and when it came back, everything seemed fine. It was not until recently, like months after the fix, did I realize that the touchpad had some problems. It felt unresponsive to clicking, as if there were something stuck and prevented the touch pad from travelling all the way down. It was also then when I realize that the Macbook did not sit flat on a flat surface (basically it was wobbling if you put force on the corners). I thought everything was fine… not until I went to open up the back cover just a month ago did I realize the root cause of all the issues.
