My 2011 MBA, and 2009 MBP both have problems with sleep, and waking. The MBA no matter what kind of sleep it goes into it wakes with a blank screen. Using deep sleep on my MBP it reboots when it completes wake up. (aka crash) Otherwise I can hibernate that one.

 

Oh if you attempt to deep sleep the MBA it drains the battery, and remains on for over an hour later. Also gets really hot, and no fan kicks on at all.

    I can't find hibernatemode = 25 documented anywhere, are you sure that's a real value?  Should be 0,1,3,5, or 7, I believe.  Anyway glad it's working for you.

    This help me too. And the following tool works just fine

     

    We just released DeepSleep 2.0 (unrelated to DeepSleep Widget with the same name) and it supports Lion and is ready for Gatekeeper. Check it out athttp://www.axoniclabs.com/DeepSleep/

    I have the same problem with my late-2009 iMac. I also tried an SMC and PRAM reset but nothing has worked, even after the update to 10.8.2

    Another possibility is flaky harware. Perhaps the non-volatile storage for the power management settings. Assuming that is in the SMC instead of PRAM then perhaps resetting the SMC will help.

    I have performed an SMC reset but that didn't help sadly. It's still doing this…
