I have a Mid-2010 MacBook Pro with AppleCare. I've had a few minor/cosmetic hardware issues:
My power cord recently started coming apart. The rubber/plastic coating around the MagSafe end of the cord has begun to fray a little bit. I've covered it with electrical tape for now. I did find this question which seems to have a satisfactory answer for this particular issue. But more interestingly:
The right-front corner of the body is scuffed and losing its silver coating. I haven't put any particular extra stress on this part of the body, but the silver coating is coming off. The left side is fine.
My left command key is starting to wear through. A layer of the material seems to be chipping away slowly; here's a picture where you can see the backlight shining through a few tiny holes. The right command key is fine.
Is it possible that I could get these issues repaired since I have AppleCare? Is it even worth taking in to an Apple Store? If they wouldn't do this for free, how much would they be likely to charge me?
