System shutdown instead of hibernate (Safe Sleep)

After upgrading to Mavericks I've been having problems with hibernation (Safe Sleep) not working, and instead causes a full shutdown that's hard to re-power back on. I have the problem on my own rMBP and my father's Macbook Air.
I have trouble getting it powered on after such a shutdown. I have to connect it to power and/or perform the 4 finger SMC reset.
I worked around the problem by disabling standby and autopoweroff with pmset (sudo pmset -a standby 0 -a autopoweroff 0), as it's the standby timeout which triggers the hibernation-turned-shutdown. I would however have preferred a proper switch to hibernation, so it does not run down the battery to nil if I forget to shutdown before a lengthy away.
If I 'sudo pmset -a standbydelay 60 -a standby 1' to test/repro the problem - the system does indeed shutdown completely to the difficult to re-power state after 60 seconds inactivity - no hibernation.
Is anyone else seeing this behavior?

I resolved my problem -shutdowns instead of hibernate.
It was caused by rEFInd, an EFI Boot Manager (http://www.rodsbooks.com/refind/) that prevented proper hibernation with its default installation.
By installing it on a separate partition instead of default on OS X Boot Volume, hibernation started working as it should. http://sourceforge.net/p/refind/discussion/general/thread/8bd60a7b/

Safe Sleep Does Not Appear to be Working

Dear Forum,
I using a 2.33GHz MacBook Pro 17” 3GB RAM 10.6.2 (FireWire HDD Start up (Boot) via a FireWire 6 port hub).
I have calibrated the battery (after replacing the original) on three occasions, however the system does not restore from the point just prior to the battery turning the system off. Instead after the battery is drained completely (after 6 hours or so) and after plugging in the charger and pressing the power button I get a grey screen, then after a few seconds the screen goes black then I hear the boot up chime and the apple logo appears.
I thought the system was able to remember where it was before the battery drained.
I have used this command in Terminal:
pmset -g | grep hibernatemode
and have received this in reply:
hibernatemode 3
but as I am using Secure Virtual Memory, I read I needed to use mode 7 so I tried…
sudo pmset -a hibernatemode 7
which returned:
hibernatemode 7
so it looks like I entered the correct command.
Furthermore, it would appear that something is happening when I choose sleep, as the Mac takes anywhere up to 30 seconds to do as I ask. (This from the sounds of it (literally) is doing what it should do (writing its current state to the drive), as I can hear the G-Drive Mini working away.)
Q1: Have I entered the correct command? (I am not fluent in the language, I was merely following directions.) (Is this command correct for this Mac?)
Q2: Can the MacBook Pro enter hibernate mode when booted from an external Firewire drive (G-Tech Mini 250GB (GUID partition))?(Apple says using a FireWire Drive to boot from is OK, at least from what I have read, so I am assuming they would have looked into various usage possibilities (Hibernate (Safe Sleep) mode, one would think is a usage possibility.))
Q3 I would prefer not to use third party software (Deep Sleep, Smart Sleep) unless I am absolutely forced in to it, as this function is written into the system (therefore should work without third party controls), so can this issue be solved with the setup I have?
Q4: Have I missed the point somewhere, or misunderstood, what the hibernate mode (safe sleep) is all about and in fact I am asking too much to expect the system to remember where it was after completely draining the battery? (Yet I don’t believe I have misread the following: http://support.apple.com/kb/HT1757)
I would very much like to get this operational as you can imagine as it is an incredibly useful feature.
Thanks.

Well the solution is: Restore from Time Machine to MacBook Pro internal HDD and Safe Sleep functions correctly.
Now how do I get a bigger HDD into the Mac...

Why does my macbook pro safe sleep instead of sleep?

After upgrading to OSX Lion, I found the performance of my 13" Core2 Duo 2.53 Macbook pro to be somewhat slow, so I upgraded the memory to 8Gb. While this seems to have made the machine a little faster, it's given me a new problem: When I "sleep" the machine, either from the menu or closing the lid, it actually goes into safe sleep. This then takes quite some time to wake up again. If I disable safe sleep with sudo pmset hibernatemode 0, the computer simply reboots.
It seems that when sleep is activated, it sleeps for a few seconds then simply powers off. I can't figure this out. I've reset the PRAM and checked all permissions. I even removed /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist to no avail. There's nothing obvious (at least to me) in the console either.
Logically, the RAM may be a problem, but I am loathe to go back to being so slow. the RAM was sold to me as being Apple compatible but maybe my local dealer lied to me? Perhaps it's something related to the battery?
Can anyone give me any tips or other ideas to pursue?

Same issue when I upgraded from 4GB to 8GB. I used Kingston's, and followed every Apple memory specs.
I don't know how to solve this. Already tried pmset, and other stuff. MacBook works fine, but this is annoying.
It is sleeping, showing the breathing light, but when I open the lid, light stops and have to force shutdown and turn it on again. When I start the system, it recovers files from disk, what means that it already was in safe sleep mode.

MBP (13-inch, early 2011) goes into hibernation instead of safe sleep upon closing the lid (only when using battery power)

MBP details
13-inch MacBook Pro, early 2011 (model identifier: MacBookPro8,1)
Running Yosemite, OS X 10.10.1 (however, problem started while using Mavericks)
2.5 GHz Intel Core i5
4 GB memory
Symptoms
* the MBP goes into hibernation instead of sleep upon closing the lid on battery power (i.e., when AC adapter is NOT connected)
-- problem does not occur when AC adapter is connected
* putting the computer to sleep by other means does not induce the problem; these other means include:
-- [i] option+command+Power,
-- [ii] Apple Icon --> Sleep,
-- [iii] in Terminal: pmset sleepnow
* the battery is NOT getting drained at all; if I close the lid on 87%, the battery is still at about 87% when I get the MBP back up and running
To be as clear as possible:
(1) MBP is on and in use (power source: battery); battery is at X%
(2) the lid is then closed
(3) the battery indicator light glows bright for about 10 seconds, then shuts off, and with it so does the MBP (all fans and sounds cease)
(4) opening the lid and pressing any key on the keyboard does nothing (the computer is not sleeping)
(5) to turn the MBP back on, I must hit the power button once; this brings up and the gray screen and loading bar indicative of returning from hibernation
(6) log in; battery is still at X%
Attempted Solutions / Fixes
There are Apple Discussions addressing similar MBP issues, many of which at least have work-arounds, if not full-blown solutions. However, I have tried many of the proposed work-arounds and solutions; nothing has solved my problem. Such attempted solutions include:
* made sure EFI/SMC firmware was up to date
* updated all software
* logged in as a different user
* booted in Safe Mode
* reset the PRAM
* repaired disk permissions using Disk Utility
* repaired additional disk permissions in recovery mode (a la this chron.com advice)
* ran the Apple Hardware Test multiple times (short test while plugged in, short test on battery, extended test while plugged in, extended test on battery)
* booted from an external known-good OS on USB drive
* reseated the RAM
* used MemTest to test the RAM's health (it was good)
* tested my battery's health with the app Battery Health (it is healthy!)
* booted my computer with one stick of the MBP's original RAM at a time (figured "why not?")
* booted my computer using other sticks of RAM
* checked my power management settings using PMSET in the terminal (e.g., pmset -g); tried various hibernation modes (e.g., sudo pmset -a hibernationmode X, where X=0,1,3, etc)
* searched/grepped through my power management logs and Console messages to look for googleable items (e.g., pmset -g log | grep WORD, where WORD=failure, sleep, etc); still have not found help online
* brought the MBP to a Mac Genius
-- he ran some further tests, but found nothing;
-- he re-installed my OS as a hopeful-hail-mary-just-maybe-last-ditch effort; the problem persisted!
-- we both agreed that we had ruled out a software cause
-- he offered me to leave my MBP to get fixed for a flat fee of $300.00 (which after a couple weeks of trying to figure this out is starting to sound more and more reasonable)
Given that it is likely not a software issue, what hardware might it be? By booting from an OS on an external drive, I think I've ruled out a bad hard drive or hard drive cable. Also, given that inducing sleep in any way other than closing the MBP's lid does not cause the problem, it seems there might be a wire (or something) in the hinge section of the MBP that gets moved when the lid is closed possibly causing some kind of short circuit...or something.
If someone with more experience interpreting Console messages, for example, can help, I'd be happy to provide some logs, or any additional information.
Thank you for your time and consideration.

Ok, this is a crazy-simple, quasi-embarrassing fix, but I'll post it anyway just in case anyone is having a similar problem (for example, this guy: Changes to pmset being ignored).
Some time around late last August / early September (2014) this issue began happening for me (specifically, issue = closing lid while on battery power induces hibernation / shut down instead of sleep --- independent of hibernation mode). Maybe it was when I upgraded to Yosemite (not sure what the exact date of that was). As detailed in my original post, I frantically tried everything I could think of... At that time, however, I had quite a few presentations and posters to create and present at meetings and conferences, so I held off fixing it for a couple of months and returned to it this past week, where I tried a few more things listed above, but again to no avail...
This morning, I simply tried fudging around with all my power management settings again (via pmset in Terminal). The simplicity of the fix surprised me. But now that I understand it, I know it is likely the same fix for other threads I've read, such as the one above:
(TLDR in bold)
(1) Take note of your power management settings (Terminal: pmset -g custom)
(2) Is the "standby" flag set to 0? If so, set it to 1. Wa-la! Done.
This fix is crazy and embarrassing b/c I was so close to it for so long. I tried changing my hibernation modes multiple times (sudo pmset -a hibernatemode X, where X=0,1,3,25,etc). I read about manipulating other PMSET settings that helped other people with newer MBPs, like "autopoweroff" and "autopoweroffdelay" --- settings that I do not have on the MBP early 2011 (check your settings: pmset -g cap). And most amazingly of all, I even messed with the "standbydelay" setting, trying to make it so long that my computer should never go into hibernation... Yet, from what I can tell by looking over my notes, I never simply set "standby" from 0 to 1.
There are interesting questions that arise due to this fix. For example, why did this problem persist on clean installs of OS Yosemite? Is "standby" being set to 0 the Yosemite default? I'm not sure. If it is, then Kappy was right: this was normal behavior... It just wasn't always the normal behavior...at least not for my MBP. Normal behavior (hibernatemode 3) used to be (and now is again) that the MBP goes into safe sleep, and then only after an allotted amount of time will it go into full-blown hibernation.
NOTE: the "standby" and "standbydelay" PMSET settings are not available in some earlier MBP models (e.g., my brother has a 2010 and does not have these settings); so if you're having a similar problem with an earlier model, this fix might not be of any help to you.

Satellite L505D-S5965 got shutdown, hibernate and sleep problem after Windows 7 upgrade

I bought my Satellite L505D-S5965 last August. Everything worked fine on Vista. Last month I upgraded it to Windows 7 (Home premium, build 7600), then it started having problem to shutdown, hibernate and sleep. Half of the time, it will shutdown, hibernate or sleep just fine, however, the other half of the time it just never turns off.
For shutdown, it will go to the shutdown screen for 10 minutes until the a blue screen comes up, telling something about windows experience a crash and dumping memory, then it restarts itself.
For hibernation and sleep, it will go to the normal black screen but the hard disk light never turns off (i.e. the hardisk would keep running forever).
It will be a big help if someone can help me with that, I just don't want to keep doing the "hard turn off".

Hey thats great posting and detailed, thank you! :)
Im wondering how you found it out.
But I want to add something: Before you do or change something in Windows registry, make a backup of it. In worst case you restore the old Windows registry. Just to be sure ;)

Safe sleep hangs on my PBG4 1.67 HR

I just installed (myself) a new hard drive (went from the stock 80GB, which was almost full, to a 120GB Western Digital Scorpio WD1200VE). I think, but am not certain, that this problem appeared then (it could also be a coincidence).
When I sleep the PB now, the screen goes dark, however the white LED *stays lit* instead of pulses. I cannot wake the computer. The only thing I can do is force shutdown and restart. When I hold the power key to force shutdown, after a few seconds the LED goes out as I expect. But when I restart, the computer instead seems to wake from safe sleep (fuzzy greyscale window), and all my apps and documents are as they were before. I say "SEEMS to wake" because when I look at the Console log, I see that my PB actually doesn't write the ram contents to the hard drive (i.e., enter safe sleep) until I am pressing the power button to restart; then, one second later it spits it right back out to ram! So, all the time I think I'm "sleeping", it looks like the power is actually on but the screen is dark and the keyboard unresponsive. There is no activity reported in the logs during the "sleep" time, though.
I have so far tried resetting the PMU, and also run Tech Tool Pro4 tests (everything passed). Also, I deleted some plist files having to do with power management I read about here. Nothing has helped. After investigating more, I learned how to set the hibernate mode via Terminal; I set it to "0" (old style sleep), and that works -- the LED pulses and I am truly asleep, and opening the lid or pressing a key wakes the PB. hibernatemode 1 or 3 (both involving safe sleep) present me with the same problem I've described.
This is a tough one, I would like to be able to rely on safe sleep when I need to. Any ideas on the cause or troubleshooting tips are appreciated. Thanks!

Hi MasterG,
Yes, it's strange. However, you have given me a a further clue. I'd already checked the sleep timeout for when the system is idle - it was set at around 10 minutes, I think.
But, following your suggestion, I started looking at all the power options resulting in sleep, and setting them all to "do nothing". I found that changing the option for when the lid is closed from "sleep" to "do nothing" causes the screen to go blank for a second or so, and some disk activity to begin, but the laptop no longer sleeps. Instead, it resumes from where it left off after a few seconds, albeit only to repeat these steps almost immediately.
As a further test, I left the "When lid closed" setting on "sleep" for when the system is running on battery, and on "do nothing" for when it is running on mains. When on mains the system behaves as described above, when on battery it sleeps as I described in my first post (although I had initially thought that the problem didn't happen at all on battery).
So, the problem seems to be something to do with how the machine detects that the lid is closed. Do you know how that's achieved in L40s? Or is there a service manual available for it that might give a clue?
Many thanks,
Rob.

Safe sleep or hibernation won't work on my Macbook 13" Unibody (late 2008)

I have a 13" unibody Macbook which I bought in October 2008. The systems sleeps well once the lid is closed but if it runs out of battery it will not hibernate. I checked the output of pmset and everything is properly set for mode 3, which is the "safe sleep". I even tried setting it to hibernate only and it still goes to sleep.
I found several people with similar problems, but nobody seems to have solved the problem. I can't believe that such a simple thing as setting your system to hibernate can be so complicated to achieve with OS X.
My pmset output is below. The sleepfile is dated back to June 20 when I removed the file and it got automatically recreated during reboot, but no updates to the file since then. I don't have PGP installed (I did but I removed) and I have the system (including firmware) all updated to the latest versions.

I have found a solution to my Mac shutting down completely without using hibernation or safe sleep. It turns out about a year ago I ran SmartSleep. A piece of software to allow you to put the mac to sleep the old way. Turns out it corrupts the Powermanagment.plist file when uninstalled. It needs to be deleted to reset to system defaults. More info here:
http://markandkelley.com/mark/?p=75#comments
Whether this will stop my mac shutting down straight away anyway I have yet to find out, but at least the contents of the comp are saved first now.

Safe Sleep! It keeps happening to my MBP. Any ideas why?

Whenever I move my MacBook Pro when it is asleep and off-AC, it will eventually drop into Safe Sleep.
There doesn't appear to ba a particular trigger, at least as far as I've been able to tell, other than to move it. It could be as simple as gently turning it over, or putting it into my laptop bag and bringing it home. Without fail, it goes into Safe Sleep.
If, however, I take it off power, put it to sleep and simply leave it sitting, it remains in simple sleep.
I'm thinking it may have something to do with the sudden motion sensor being bad or overly sensitive. Here's the Console Log from putting it to sleep until it goes into Safe Sleep and, when I reopen it, awakes:

Is there already a solution to this problem?

I am also having the same problem, although I'm on a PowerBook G4 12" 1.5Ghz.
I have an Apple Wireless keyboard and a Logitech BT mouse. The PowerBook is set up not to wake the computer using any BT device.
On two occasions, the computer woke up from sleep because it somehow lost the BT keyboard and mouse connection. Upon close inspection, that shouldn't have been possible, since that option was off.
I subsequently checked the BT preference pane under System Prefs. There, I discovered the following message, "Bluetooth Device Name: Name not available."
The first time, I restarted the computer and everything came back to normal. The second time it occurred, it I decided to log off and log back in. The log in process was fine, but my icons on beside Spotlight wouldn't load, System profile froze when getting more information on my BT module, and System Preferences also froze when trying to access the BT preferences. I ended up restarting the computer, and lo and behold, it worked again.
This has happened twice in the last two months, and I can't replicate the problem. I also can't figure out if this is a hardware or software problem.
I've read posts in the forums that describe BT going missing. This is not the case for me. BT is there, but for some reason BT is there but it's "Name not available."
Plaese let me know if you figure something out.
Cheers,

Stuck with safe sleep

My macbook has recently stopped going into normal sleep when I close the lid. Instead of going to sleep, it will go to safe sleep and shut down. I have tried swapping the battery with a friend of mine but to no avail, the laptop will always go into safe sleep.
How do I restore normal sleep behavior?

Hi spotmaxdog,
To check the sleep mode enter this command into terminal:
pmset -g
look through the list for "hibernatemode"
The default for MBPs is 3.
0 = off (normal sleep mode)
1 = on (exclusively hibernate mode, memory is dumped to save more power)
3 = on (hibernates as well as sleeping... keeps memory on and hibernates as a fail safe)
The 3rd option has the best of both worlds because it wakes quickly but still has the safety of hibernate mode, however it still has to save memory to disk so sleep is not instant.
to set the mode type this:
sudo pmset -a hibernatemode 3
If you only want normal super fast sleep (like the powerbooks) then use mode 0. However you cannot swap the battery with this mode as the MBP's don't have internal backup batteries like the powerbooks.

MacBook Pro 6,2 always safe sleeps on low battery

Hi folks,
My new 15" MacBook Pro 6,2 (Core i7) is behaving differently from my old MacBook Pro 1,1 when it comes to sleep.
My old MBP, when the battery reached 0%, would go into normal sleep mode, and it would actually continue to sleep for quite awhile before it would finally power off. At that point, if I powered it on, it would resume from safe sleep, but if I booted it before the normal sleep mode's reserve battery strength was depleted, it would just wake normally.
My new MBP will, when the battery reports 0%, instantly go into safe sleep mode and then power off entirely. Resuming from this state is always from safe sleep, even if I connect power as soon as the screen darkens.
Is this new behavior or is there something awry here? If this is within spec, is there any way to get the old sleep behavior back, where some amount of the battery is "hidden" so that below 0% there's still reserve enough for the machine to sleep for awhile before going into safe sleep?
I haven't tried any troubleshooting steps or reset anything yet because I wanted to find out first whether or not this was normal.
Thanks folks!
Tim

That's how my unibody 15" has always behaved. The change to full "hibernate" has been in effect for awhile (it might have come about with the release of 10.6 - I don't recall it being that way in an 10.5.x release).
There are command line hacks to get around it, and you can google for those. Personally, I like the way it works and I imagine it has to do more with preserving battery health than anything else. Li batterys do not take well to really deep dischages and need to be kept always with a minimal residual charge. By going into hibernation instead of safe sleep, there is less risk of a battery discharging too much if inadvertantly left sitting unplugged for too long with some residual power draw left on (ie. maintaining the RAM state in sleep mode).

Hi @Ahmed-Aslam
I understand that you are have problems with hibernate and sleep on your notebook.
I would review the attached document. I realize from your post that you have tried some of the things listed, but just check it and see if anything there was missed, perhaps the section on malware issues.
Troubleshooting sleep and hibernate issues in Windows 8
You can also try using system restore to roll back to before the software update to see if that resolves the issue.

Application messages are in the system log instead of the application log

Hi SAP GURUS.
The standard output is created from the outbound delivery .
All the messages are hitting the system log instead of the application log .
This is after the upgrade from 4.6c to ECC 6.0 .
Please provide the details how to move the log to the application log since the output is the standard output (SAP provided output type ).

Do these messages indicate a problem? If so what that could be problem and the solution?
Can this contribute to the sleep/wakeup problem when iMac won't wakeup after being put to sleep manually and not sleeping according to Power Saving settings?
Thanks a lot.

I'm not certain if those messages indicate a power issue but you can try *resetting the System Management Controller* and see if that helps. Here's how: http://support.apple.com/kb/HT1806
"The System Management Controller (SMC) is a chip on the logic board that controls all power functions for your computer. If your computer is experiencing any power issue, resetting the SMC may resolve it. The SMC controls several functions, including:
Telling the computer when to turn on, turn off, sleep, wake, idle, and so forth.

Finish system shutdown with closed lid

The system goes to sleep after a shutdown is issued (press powerbutton and click "Shutdown" ("Ausschalten" in german locale)) and the lid is closed while the system is still busy with the shutdown process.
How can I prevent the "go to sleep" and let the system shutdown cleanly even with the lid closed?
This happens on an iBook G3 (PowerBook4,1) with 10.4.11.

Pressing the power button for that long would cause a hard shutdown AFAIK.
I found a kext which, from the description, seems to do parts of what I want:

Now all I need to find out is to do it only when the system is about to shutdown.

What is default terminal setting for "safe sleep" for iMac C2D

I happened to use a widget for "deep sleep" which frankly I decided I did not need. Of course, after trashing same per the widget directions - the widget had changed a "setting" effecting sleep on the computer. Silly me.
There was an article in MacWorld last fall about "3" being the safe sleep mode to set a laptop (recent) from the terminal command line...but no reference to the iMac .

Not a major crisis, just want to set the "sleep code" number back to how the unit shipped from Apple!

When I had the widget installed, I set it for "deep sleep" if I recall properly. After deciding to trash the widget and its preference file, I noticed that when I put the computer to sleep via the "apple" menu - the light on the monitor quickly went out entirely.
Although I could still "rouse" the computer the by tapping the keyboard etc., the wake up process was extremely slow - in fact, the computer opened up to a gray version of the desktop ...followed by a progress bar...which when completed...opened the desktop to its full Apple glory.
Perhaps, the widget set the computer to the hibernate mode - etc. I actually set the computer back to "0" via the terminal command...but since I didn't know the original default setting, I thought I'd ask...and sadly, I could not find the answer anywhere...hence the query to Apple users.
Thanks for the info, though.
