Hi, I just got my fiance a new macbook air which I researched thoroughly before deciding to go for the standard 13' model. I got it from the nearest store, unboxed it and completed the registration part. 10 minutes after logging into Lion, I am unable to use the trackpad and keyboard. I tried to restart Lion many times but its not usable at all. Any idea what the issue could be? I barely lifted it off from the table and everything was working well during the first boot up.. This is so frustrating because it's suppose to be a surprise for her. I went back to the store immediately and they are reinstalling Lion again. If it still doesn't work, they will replace it. Any ideas on what might went wrong?
