Needed a Battery, wanted OEM, went to iFixIt!

Mi Problema

A bulging battery makes for difficult TrackPad clickery.

Mi Solución

Very easy. Ten screws to remove the bottom case cover and three more to remove the battery. Unplug the battery and replace with new.

Mi Consejo

Shutdown the system first, obv. Also, be sure to have the unique screwdriver for the battery screws.
