My Macbook is going nuts. As soon as I turn it on the fan sound is crazy, and it starts at around 70 degrees, nearing 78/9. Of course it is out of warranty, but I want to take it to my local genius bar. I have never gone there before. Is the initial appointment free? Also, just a question....my actual keyboard area of my laptop, sorry I don't know the name of it, but all of the white area (list where my wrists rest on the keyboard..) can that be replaced by apple? The edges of mine have cracked a bit, and I have a lot of scratches and marks on it. It is just cosmetic- something that bothers me and doesn't effect the performance of the laptop, but just curious if it could be replaced. Thanks!
