    June 2012 MBP 2.6Ghz I-7, 16GB RAM, 750G 7200 RPM HDD, non-retina, 1680x1060 screen.
    OS X 10.8.2

    I noticed a week or so ago, that my MBP has started, on occasion, to waken slowly. It is as if it is loading a lot of stuff- long enough that it starts to wake up but takes long enough that it will blank the screen again before it becomes functional and I can put in my password. Neither the mouse pointer nor the keyboard are responsive.

    Once it awakens, it is just fine- no problems, no crashes, no change in performance.

    Thoughts?

    Sure is.. I wish I could sleep this deep. The problem is not consistent. This morning it was fine after resting overnight. Yesterday, it was not.


    Aside: Love your handle.:)

    Could you please share the results of pmset -g (in Terminal).

    Sort of hillbilly tribute to Hayseed Dixie :)

    Only if done right...

    I'm at work now, so when I get home this afternoon I'll run the pmset -g and post the results.

    Might want to get rid of the sleep image and disable it.

    Remember, everytime you close, it needs to update a huge 16-20GB file (since you have 16GB of RAM). When you open the lid it accesses the image as well.

    My 2011 MBP (15") came with a 750GB HD and I updated the ram to 16GB and switched to an SSD. The resume time went from 5-10 seconds to 1 second. I erased the sleep image to save space as well.

    Sounds good. If I knew what to do, that is. LOL I have no idea what the sleep image is (though I suspect I know.) I also have no idea where to find it.

    Did you install MacBook Air and MacBook Pro Update 2.0? (at the beginning of November)

    You have standby 0, so in theory your MacBook should not go into deep sleep/hibernation after some time, only in case of low battery power. In theory, because the update I have mentioned messed up big time. Try increasing standbydelay (seconds) to significantly bigger value to prevent the switch.

    There are some reports that switching to hibernatemode 0 and re-creating sleepimage file with restricted access helps, but my impression is that nothing is sure.

    Yes, my software/firmware is up-to-date.

    I'll try those suggestions and see how it goes for a few days. As I said, if there is a trend to when this happens, I have yet to discern it.

    This setting controls how long the system will remain asleep, in seconds, before going into "deep sleep", which means writing the contents of memory (all 16GB) to disk.

    Once it's in deep sleep it takes longer to wake up because it has to read 16GB from your disk back into memory.

    4200 seconds = 70 minutes. I set mine to 24 hours using:

    sudo pmset -a standbydelay 86400

    So now it wakes up instantly if it's been asleep less than 24 hours.

    Thanks, CausticPuppy. I made that change. I'll see if that helps.

    Isn't it taking more battery that way?

    Not sure about the battery thing, but it did the job. Since I made this change, I have not had one of the deep deep sleep issues.

    Since my laptop is normally used plugged in, battery life isn't a real issue. I have an Air when I need portability.

    Oh- and many thanks to those who contributed suggestions and comments. Much appreciated, people!

    Technically yes, but it literally only drops a few percentage points when sleeping overnight. It hasn't been an issue at all.
