Hey everyone, This is my second technical help post of the day...sorry! I have the new 2.2GHz Macbook and its great. However, a few of the keys, most significantly the "a" key, sometimes do not register when depressed. I'll often hve to push the "a" key 2 or 3 times in order to get an "a" to appear on screen. This is so frustrating! Is it something I can fix myself or do I need to see a genius about it? Is anyone else having this problem???? Thanks for your help!
