My magsafe adapter is now getting extremely hot, and unless i keep it in the exact position when i get the light to turn on, it doesn't work. i've already had 3 replaced, and even bough one myself, which had the magsafe fall off the cable (and they refused to replace because they said it looked like i abused it). I have the first gen macbook, so I'm out of warranty. Is there anything I can do to get them to replace it anyways, since its obviously not me?
