What can I do to keep my trackpad button from failing?
My trackpad button on my trusty old MacBook has been a little odd for a while now (clicking feels uneven; I get a nice, solid click from the left side, a soft click from the right, and almost no tactile feedback in the middle).
Yesterday, The button was clicking when I was just typing. I don't have tap-to-click enabled, and I definitely was not pressing the button. The most common causes of this problem appear to be spill damage and a swelling battery. I've never spilled anything on this computer and my battery does not appear to be swelling.
The button seems to be back to "normal" today, but this made me very concerned that I would either have to get a new top case or disable my trackpad (I would hate to carry a mouse around with me everywhere).
So even though my trackpad is working "fine" now, it may have problems again in the near future. What maintenance can I do to keep my flagship machine in usable condition?
Is there a way to remove the button and remove dust from that area? Since this computer is in its 5th year of use, I'd imagine there's some amount of dust in it. Either way, I'd like to have a look at the components that make it up - maybe some spring is no longer working properly or something.
I'm familiar with replacing the upper case, which I did for my sister's MacBook, so I'm mainly wondering which side to attack this problem from.
Any and all information you have on this subject is helpful! Thanks!
