Not sure if this is appropriate for here, but in researching online why my trackpad is no longer clicking with ease, I discovered it may have to do with the battery swelling beneath it. Given how crowded the Apple store always is (if it's even open right now,) I found a youtube video on how to replace it myself.
It's a bit complicated requiring adhesive solvent, and a tricky method of pulling string down behind the battery segments in an effort to dislodged the battery from its glued backing.
Any suggestions or recommendations or lessons learned? (Mine is a Retina, 15-inch, Late 2013.)
