My macbook pro on Lion will not sleep, it was a problem on Snow Leopard as well and continued through the software upgrade. I've tried a lot of remedies and nothing ever works. The problem is that it just won't turn off with the lid open, every other way it will, just not with the lid open. So let's solve this. It has to be some software im running but i can't figure it out for the life of me. Ready to answer any questions.
