9 Letters From The Keyboard Don T Work Macbook Pro 15 Retina Display Mid 2014

Chosen Solution

Changed the DC-inboard following the instructions in my MacBook Pro 15" Retina Display Mid 2014 . Now the keys from Q-O don’t work. The keyboard worked fine before I started the work. Thanks

Either the keyboard ribbon cable is not inserted fully into the ZIF connector or the keyboard ribbon cable got damaged during the repair. You’ll need to replace the keyboard if it is damaged. The keyboard is held in by pop-rivets so it is quite difficult to replace which if I remember correctly also requires removing the adhered battery carefully.
