Well today I noticed that in one part of my macbook charger the wire is peeling. You can't see any of the wires underneath but some of the white is peeling off. Is this a big deal? Also my Macbook is about 5 months old and I got it at Best Buy. I got a warranty so would I be able to get another charger for free do you think? I don't think this should happen to the cord after only 5 months.
