So this is just plain weird, and I'm hoping someone can shed some insight. I live in Durango, CO, at 6,800 feet above sea level. I have 3 friends of mine with 15" AlBooks, and I just got my 1.5ghz 15" AlBook, and here is the problem we ALL experience: The power adapter will just come out. It's like it's all the way in when it has a mm left, and you give it a good push to finish it off so that it is charging, but randomly you'll notice that it has gone back out to the 1mm out position. I thought this was a general problem, and was wondering why more people weren't complaining, however, I am writing this from Hawaii, and the pluug is in solidly, and not coming out. So I am led to believe that it is related to Altitude. Theories on what's going on?
