So I have a Late 2009 Macbook Pro, it came with the original magsafe adapter. The adapter doesn't always work all the time, sometimes theres a really dim green light. One of the prongs that go into the wall is slightly bent so it might be because of that. My question is will Apple replace this charger for me? Do they give the new magsafe adapters as replacements or will they give me an old one? Thanks alot macrumors!
