Doesn't work...

I really like the solution you described. However, it doesn't work with my 2012 macbook pro 13" running 10.8.3. A couple of the commands are apparently invalid. It suggests that I lookup the man page for the appropriate usage...

Any other ideas?

In the meantime I just used the commands listed below. They all ran just fine. Now we see if the problem is fixed. I found the commands here:

sudo pmset -a hibernatemode 3
sudo pmset -a autopoweroff 0
sudo pmset -a autopoweroffdelay 36000
sudo pmset -a standby 0
sudo pmset -a standbydelay 36000
sudo pmset -a acwake 0

Well, this sure is an odd issue to say the least. If my new Macbook Pro (2012, cMBP) stays asleep for a few+ hours, it's no longer asleep but, as best as I can describe it, it's hibernating. The sleep indicator is off, the power charger is plugged in, but when I open the lid, the screen is grey and it's like an indicator bar is filling up before it will show the desktop. If I let it sleep for a few minutes it comes up with no issues.
Hi! I've had exactly the same problem, but not anymore :) I've resolved it!
Just go to System Preferencies/ Security & Privacy/ FileVault and turn it off!
Hope you will like this advice?!
