Changed in a snap

Mijn probleem

Old battery did not charge any longer. The computer still worked when plugged but the original battery was gone.

Mijn oplossing

Super easy. The Mac store person showed me the instructions and video on how to do it. It went without any surprises.

Mijn advies

Follow instructions to a T. I would put a towel underneath the computer, as it prevents the screws from rolling off the table or surface you are working on, and prevent scratches on the case surface.
