Nothing is more frustrating than when something you need to work, doesn’t.
Problem
I’ve relied on my MacBook Pro and it has been very good to me for the last five years (a long time in computer-land). Recently, I noticed the mouse and mousepad freezing or locking up intermittently – almost as if something or someone else were controlling it. Could it be a computer virus on a Mac? I didn’t think that was possible.
This morning I booted it up to begin my day and could not get the mouse to work at all – totally frozen. After ten reboots, another “clean” virus scan and having to make a conscious decision not to slap it – I finally turned to my iPhone to search Google for a solution.
Sure enough, I am not the only one with this problem.
The symptom was being caused by a lack of “pressure” against the mouse trackpad and the battery itself (which sits directly under the trackpad). Apparently, the battery must warp over time when it heats and cools, changing it’s structure so as to not create enough pressure under the bottom of the trackpad.
Solution
Remove the battery and place a 3/4 inch piece of cardboard between it and the trackpad.
Thanks to this coffee cup holder, Google and a few friends at MacRumors Forums – I saved myself a trip to Fry’s, maintain my sanity and continue to put food on the table for my family.

Moral of the story
Use Google before you hurt someone and/or waste money.
