Hello,My Macbook Pro’s Keyboard and trackpad simply stop working at random moments while in use. Bluetooth keyboard and trackpad still work fine, but this isn’t a fix. Resetting PRAM doesn’t work. Restarting the computer repeats the process, but is a temporary fix to the problem.This also means that the issue isn’t the connection, so I am unconvinced replacing the parts would work. Are there any other troubleshooting options to figure out why the system is failing? Thanks.

Time to replace the keyboard or the uppercase assembly. This series has a much more serviceable keyboard as its screwed in! Sadly its a ton of screws. But the keyboard is quite cheap MacBook Pro Unibody (A1278) Keyboard here’s the guide you’ll need to follow to get to it MacBook Pro 13" Unibody Late 2011 Upper Case Replacement as well as a new trackpad MacBook Pro 13" Unibody (Mid 2009-Mid 2012) Trackpad
