I have a late 2012 MacBook Pro 13'. I've faced a strange problem: my Macbook does NOT switch into sleep mode when the lid closed. Same when open the lid - it does not wake. Instead of closing/opening the lid I have to use the Power button. It seems to be a mechanical problem, cos I've reinstalled mac os and it was in vain. Guys from my local official apple service said, that there is probably a lid-open/close sensor failure. But all they supposed to do - buy the new motherboard. Bad idea=) So, maybe you do have some ideas about that? Have anyone faced the same problem? Or maybe you know something about this sensor?
Here's the result of pmset -g
