My macbook is great. There is no mooing no whining. When it is idle, it sticks around at 53 centigrade. Not bad considering some people claim theirs are at 60! Mine only gets to sixty when it has a 40% CPU load. It does get hot from time to time, but that is only when the CPU load is at 50% or more. With the things I do, that is almost never... Only problem is that damn K key. The K key keeps sticking. If i press it down a bit to the right, it sticks down. It can take from half a second to a full second for it to come back up. No matter how much I try to ignore it, it annoys the hell out of me. So today I took it to the Apple store. The guy said I can either replace it, or I can fix it by replacing the whole keyboard. Im going back probably tommorow, however Im not too sure of what I should do. Replace or fix? If I fix, i run the risk of it starting to moo or whine. My thing is dead silent until it reaches 70 degrees centigrade. Should I just replace it? Fix it? I guess I can always ask the person who replaces it for me that I want the most recent one that came off of the factory lines. Get something between the weeks of 22-24th week of this year? Right now have a 22nd and it shows no flaws other than the damn keyboard.
