My trackpad will work for about a minute or so after startup and then stops completely. Is it possible to replace this part? I don’t see any parts or instructions on iFixit. Many thanks!
While the Both the 13" & 15" models use the same procedure MacBook Pro 13" Retina Display Late 2013 Trackpad Replacement to gain access to the trackpad (technically a touchpad). The 13” model uses a different part MacBook Pro 13" Retina (Late 2013-Mid 2014) Trackpad which won’t work in your 15” model. You need this part: MacBook Pro 15" Retina (Late 2013-Mid 2014) Trackpad. @ajcooke01 - Replacing the full uppercase is not really needed here.
I bought a new upper case for my late-2013 15" MBP. It included the keyboard but not the trackpad. I’m hoping these instructions for the 13" MBP will be all I need to transplant the trackpad to my new(er) upper case. I have a new battery to install too.
