Of course you have a MacBook Air, I didn't want to imply you are a liar!
Ok so, wow, I just got mine on tuesday, been working with it a helluva lot. Now, yesterday, out of the blue it got realllly hot, the fan started blowing at full speed and the 2nd core shut down and it kept lagging for minutes on end. I had to manually power it off (as in hold down the power button until it died).
I was installing xcode from a .dmg and writing an email in my parallels (ubuntu). It seems to me as if I had taxed the system much more in the past.
When it started making the noise, I just put it on the bed for 1 minute, after the fan started acting up, i put it next to my window, and as you can see by my user profile, I am in canada, so next to my window it's about 0 degrees.
Was that just some oddity or do I have to expect similar episodes like this in the future?
as in: replacement y/n?
