I've had my MBA 13" for some 6 months now. Very happy with the machine, but I experience some strange, random freezes that I've need had with any of my other Mac computers the last 10 years. A couple of times a week, my MBA just freezes. No warning, no nothing. The mouse pointer just freezes and the computer does not respond to anything. Only option is to hold the power button for 3 secs and restart. These is no system or order in when it freezes. I seems to have nothing to do with what I am doing, and it might even freeze by itself when left alone some time. I also seems to have nothing to do with entering / leaving hibernation. I've tried the reset smc some time back, but didn't help. Any suggestions??
