New MacBook Airs Experiencing Logic Board Issues?
Apple Discussion forum user, DanRyb, basically stated that his 11-inch model would randomly display "weird colors in vertical lines" extending across the entire screen and the machine would freeze. He was forced to power cycle the computer in order to recover.
Another forum user, Hobokendippy, reported that his 13-inch model had crashed three times twice with a blank screen and once with the screen distortion reported by DanRyb.
In addition to the video distortion, Cult of Mac staff have reported several kernel panics experienced on both the 11-inch and 13-inch models, although the extent of the problem is not yet known.
Macworld chimes in today with its own report on the issue, offering a firsthand experience with similar issues:
Sadly, I can personally confirm these issues: Just two days after unboxing my 11-inch Air - the base model with 4GB of RAM - the notebook randomly cut to a gray screen during Screen Sharing and only a reboot could cure it. In the ensuing days, I've seen my Air's screen turn a variety of colors: gray again, tan, gray-black, and - on Monday - blue! (Let's everyone get their Blue Screen of Death jokes out of the way now, please.)
As I was working on something different in every instance, it was hard to say exactly what triggered the crashes, though Screen Sharing has been the culprit at least twice. Neither a PRAM nor SMC reset did much to help.
