Swollen Battery Causing Trackpad Issue
5 - 10 minuten
The issue grew over time, but the use of my MacBook Pro Mid 2009 trackpad started to become hard and difficult to click. Looked for a few options online, two things seemed to correct the issue. A new battery (last option) and tweaking a screw under the battery (first option). It ended up being a swollen battery that needed to be replaced for the system to be back to normal.
The repair was less then 10 minutes with the correct tools (buy a tri-wing screwdriver for this repair if your model needs it). The part quickly and simply replaced the existing swollen one. Once it was replaced, the trackpad worked without issue. Like having a new machine once again.
Have the right tools for the job before you start. (#0 Phillips, T6 Torx, and a Tri-Wing Screwdriver depending on your model).
Hard to determine if it was the screw or battery issue with nothing to compare it too. Once I had the replacement battery in hand, I could see just how swollen the old battery was and how it was impacting the trackpad.
This is a quick do-it-yourself job. The replacement product from iFixit was a drop in and go solution.
