Hey all, I bought my wife a 13" MBA because I understood them to be bullet proof.....the story I heard from co-workers around me is that after 5-7 years, it will still run as good as the day you bought it. Well, in under a years time, my wife has been able to find a flaw. The problem is that it locks up randomly. Sometimes it's while using it, but more common when the lid is opened and it's waking up......I can move the mouse, but no app will open or respond for that matter. I have visited the Genius bar 3 different times....they ran diag testing and all passed. Eventually I turned to calling Apple support. After speaking with several senior level guys, I was asked to send it in whereby, the logic board was replaced. I have already freshly installed the ios from factory but even with the replacement board, the MBA is still locking up. During the time I sent mine in, I had no other option but to buy another one from Best Buy to use as a loaner....during this time, I installed the exact same softwares that mine had...it ran flawlessly....never a lockup. Now the Apple guys is wanting me to partition and reinstall the ios again. I already asked for a swap out....telling him that this "lemon" is better off in their hands to dissect and tear apart.....but to no help from them. Somebody, help me out!!!
