I ran into a few problems with my new base i5 13"mba. I had lion completely froze just a few moments ago. It's really weird since I never experienced the issue using any of the betas on the 2010 mba. Also my magsafe and computer is not charging anymore.. I left my mba unplugged overnight and when I got up it wouldn't turn on. After plugging in the charger I could get it to turn on, but the magsafe light would not go on. Also it would say was that it was not charging, but plugged in. I did a smc reset once and fixed the issue. I just hope I will not have to again. I have an appointment tonight to go the my local apple store, but wanted to see if anyone else was having a similar experience.
