this happened me, and i took my mac in to get fixed, and then mentioned to him about the adapter, and as soon as i showed him it, it looked like he was going to cry. he was like yeah, i'm going to spare your life here, and just gave me a new one, even though my applecare was void because i spilt milk on it two years ago, although i got the computer completely cleaned and fixed. and still they blame it being broken on the milk!
i don't think.
