I have a MacBook Pro. After 4-years of use, the right side of the trackpad has completely collapsed. It can no longer be pressed. The left side has risen significantly, but is usable.
Given how a MacBook is built, is it possible to open it up, remove the battery, and maybe tighten some screws (or whatever) to level out the trackpad?
MacBook Pro (13", mid-2012)
I've already opened it once to upgrade to a (256-gb SSD) and (16-gb RAM).
