MacBook Pro 15" Mid 2014 Battery Replacement and keyboard replacement.
Il Mio Problema
Extend lifespan of laptop by replacing battery and worn keyboard.
La Mia Riparazione
Frustratingly tedious and difficult, but worth it. Broke the microphone connection, but that doesn't really matter.
Il Mio Consiglio
Take your time with connections, as once broke, they are not fixable.
