Mar 15, 2013 8:22 AM in response to SwankPeRFectionby emailsfh,Thanks. That's good to know. I'll tinker with the settings to customize them to my needs. Its helpful to have the difference between standby and autopoweroff spelled out because that was confusing to me.

Mar 15, 2013 8:44 AM in response to emailsfhby SwankPeRFection,Ya, I don't know why Apple just didn't have one setting and allow it to work in both profiles respectively. I think it's some kind of antiquated OSX issue maybe. You don't see Windows have different terminaology for sleep or hibernation based on which power profile it's currently in. So I don't know why Apple thinks its a good idea to have meaningless settings in there that do nothing in one profile and something else in another.

Mar 15, 2013 8:53 AM in response to SwankPeRFectionby emailsfh,A few more questions. So having standby set to 1 on AC adapter has no effect at all, because it is strictly for battery hibernate, right? Also, even if I play with these hibernation settings, hibernatemode 3 will still allow the computer to hibernate on low battery regardless?
For example, I have standbydelay set to 4 hours, but if the computer only has 3 hours of battery life left when I close the lid, hopefully it will hibernate when the battery gets too low, rather than completely drain the battery and die waiting for 4 hours?

Mar 15, 2013 10:37 AM in response to emailsfhby SwankPeRFection,Yes, that's what I said. It's the hibernatemode setting that dictates safesleep behavior.

Apr 21, 2013 2:20 PM in response to chocobananaby knmac,Since I plugged its power adapter into an uninterruptible power supply, my MacBook resumes quickly after sleeping overnight. My guess is that the power coming from the wall outlet was fluctuating during the night, enough to trigger a "restore from disk image" rather than the preferred "wake from memory." Get yourself a small UPS and the problem should go away. See this excerpt from the system documentation for the power management set utility:
The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from disk image.

Apr 21, 2013 4:57 PM in response to knmacby hockeymagnet,Interesting but I don't think that's the main issue. If autopower off is set to 4 hours, anytime up to the 4 hours MBP will awake from sleep no problem. After that, it does the hibernation thing. Change the autopower off to disabled and no hibernation. This is very consistent and has been documented multiple time. Nothing to do with current fluctuation. I'm not saying the UPS means nothing but its not the real issue. Also not a practical solution if you use your MBP in multiple locations, hotels, etc.

This is incorrect.

Apr 22, 2013 3:51 PM in response to SwankPeRFectionby knmac,I'm describing what I have observed with my recently purchased MacBook Pro and quoting from current Mac documentation. What is "incorrect?"
-
Apr 23, 2013 6:00 AM in response to knmacby SwankPeRFection,What you posted doesn't apply here. This is a specific issue that's been throughly documented and we know exactly why it happens on 2012+ laptops with a certain version of OSX and higher on it. Your two postings in this thread and another do not apply. That's what's incorrect.

Apr 23, 2013 4:23 PM in response to SwankPeRFectionby knmac,I have a "mid-2012" MacBook Pro running 10.8.3 which I see is what this thread has been recently discussing. I experienced slow restart after more than four hours of sleep with a progress bar displayed during what apparently was a restore from disk image. Since plugging the power adapter into a small UPS, I have observed a return to fast recoveries after long periods of sleep, which I interpret to be the desired "wake from memory". So things are back to the way I would like them to be and I thought to share my experience. I'm curious to know if anyone else has seen this unexpected benefit from using a UPS.

Apr 24, 2013 7:56 AM in response to knmacby SwankPeRFection,What you're experiencing is not due to a UPS thing... Leave your system sleeping for over 14400 seconds and it will hibernate. That is the timeout setting for entering hibernation (where you see the progress bar at the bottom) when the system is plugged into power and clamshell closed to enter sleep. Only dark-wakes (read up on what it is if needed) would keep this 14400 second timeout from happening and would inherently keep the system from entering hibernation. Additonally, SSD equipped machines look a bit differently even when woken up from hibernation because of the speed of SSD and the quickness of the wakeup out of hibernation process on those system.

Apr 24, 2013 8:02 AM in response to SwankPeRFectionby kellyfromfayetteville,I posted about a month ago saying that mine has stopped hibernating. It has been going on well over a month and it no longer hibernates. I now charge it all the time over night and I have no issues. I did not change any settings like the majority of you did. All I have done is do the software updates that have appeared on my computer. I bought a brand new MacBook Pro in January, had it for a week and the hibernation issue started happening, after 3 days of working with Apple they gave me a brand new machine and the problem occurred the very next day. I came onto the boards and saw it was a known issue. I decided not to change the settings on my machine and to wait it out. Something happened with one of my software updates because I no longer have the issue. Sometimes it is better to wait it out then changing settings on your machine.

Apr 24, 2013 8:08 AM in response to SwankPeRFectionby emailsfh,Swank, knmac did say that he experienced this behavior previously after 4 hours / 14400 seconds. Now it no longer exhibits the behavior. While I think this has nothing to do with power supply, Kelly is also saying her problem is gone. Apple may have snuck an update in?
Kelly or Knmac, can either of you go into your terminal and type in the following: "pmset -g custom". This will display what your current settings are showing. Then paste in the resulting text so we could all see. This should settle it if others on this board who have experienced the problem can replicate your results using your settings.

Apr 24, 2013 9:09 AM in response to kellyfromfayettevilleby hockeymagnet,Can you run pmset -g and Telly's what yours says. Possibly all that happened is that the settings have been changed. I don't agree you should just "wait it out" since changing the settings as described is harmless and solved the problem immediately

Apr 24, 2013 4:38 PM in response to hockeymagnetby knmac,MacBook Pro contains a spinning hard drive, not an SSD. The only things I've done to fix the long wake from sleep problem have been to read threads like this, accept all of Apple's software updates, and plug the power adaptor into a UPS. I have not changed any settings using the pmset utility. The machine now reliably comes out of sleep very fast after all night or all day with the lid closed (more than 4 hours). The white sleep light pulses when I leave it and is still pulsing when I return to wake it up.
