As I outlined in [_Recent software problems_](http://cdevroe.com/notes/recent-software-problems/):
>”Since upgrading to Lion my Mac isn’t going to sleep. It is frustrating as I’m the type of person that never, ever shut my Mac down. Instead I usually would just close the lid and be on my way. But, now, when I come back to my Mac the fans are spinning and in some cases the battery is drained. I’m hoping that a forthcoming update to Lion will fix this otherwise I may have to take drastic measures.”
This problem continues. However, I ran across [this solution](http://www.adeepbite.com/lion-seems-having-insomnia-it-doesnt-sleep-easily/) via a few Google searches.
1. Unplug your Macbook Pro.
2. Put the Mac to sleep (Apple Menu -> Sleep or close the lid)
3. Once asleep, plug your MacBook Pro back in.
I’ve confirmed that this works. I’m still looking forward to a Lion update that addresses these and my other issues.
