Hi all, This morning, I put my 2013 MacBook Air in my bag and went to work. Four hours later, I took the computer out of the bag and it was blazing hot and fans were running high. The battery had drained by 40% during those four hours it was in the bag and the fans were running. I have no idea how long it had been running like this, but it wasn't like that when I put it in the bag this morning. Activity Monitor only had a "kernel task" taking up 7.5% CPU and Dropbox with roughly 3%. I restarted my computer and the problem went away. My questions are... 1. Did I potentially do damage to my computer? 2. What could have caused this? I don't have PowerNap enabled. I'm more concerned with question 1. I'd hate to think I damaged this great computer after only owning it for a month. Thank you.
