Changed in a snap

Meu Problema

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

Minha Solução

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

Meu Conselho

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.
