First post guys. I got a new MBA (11" 2012 i5, 8 gb RAM, 256 gb ssd) a couple months ago. I have only a minor problem but I want to know if it is something I should be worried about. Occasionally when I open it up it is slow to wake up. It will sometimes waits ~10 sec before I can enter password. Twice it has froze momentarily and then gone to a error screen saying it must restart. Any thoughts? Thanks!
