The battery was replaced last year. Still not holding a charge. I purchased the mag port replacement part. Do I need to get the logic board or the I/O board. Or is there some other part I need to get that is related to this type of problem?

@danj you posted an invalid link, heres a corrected version. Lets get a bit more diagnostics, complete the guide I have attached below.

If you are unsure how to attach an image to your existing question I have also included a guide on how to do that also. How to Test a Mac Laptop Battery Adding images to an existing question
