Why do Apple laptops take so long to sleep??

[Astroboy907]

That should only happen if you left it in the car during the day (where it gets really hot - that's also bad for your battery).

On the same computer (stated above) I will only lose ~15% battery from a 6-7 hour laps while in "sleep" (not hibernate - hibernate i lose 1-2%).

I think I might've put it in the car, or carried it with me. IDK, it's old and crotchety and grumpy, but it only happens once every 3 months or so, so I put up with the grumpy old fart 😀

Here's what Terminal said:

standbydelay 4200
standby 0
halfdim 1
sms 1
hibernatefile /var/vm/sleepimage
disksleep 10
sleep 0
hibernatemode 0
ttyskeepawake 1
displaysleep 1
acwake 0
lidwake 1

I have a 2012 Macbook pro.

Run these one by one in terminal, see if that works:
sudo pmset -a hibernatemode 0
sudo rm /private/var/vm/sleepimage
sudo touch /private/var/vm/sleepimage
sudo chflags uchg /private/var/vm/sleepimage"
sudo pmset -a autopoweroff 0
sudo pmset -a standbydelay 72000

On my late 2011 MBP, I get instant wake up, shut down, and sleep with these settings.

I don't understand... I've said a couple times that I am running Lion, and Apple said only Mountain Lion has safe sleep, so why would my slow hard drive prevent the computer from going to sleep quickly?

That's wrong. Safe sleep has been around since 2005:

And you wouldn't even care if it's still writing RAM bytes to disk while you start tossing it around. G-forces don't bother SSDs.

Did I say anywhere in my post that I toss my laptop around after it sleeps? Nope.

No, I just wanted to stress SSD's acceleration-tolerance. In HDD times, it was suggested not to lift/move your laptop before it hibernates (LED starts it heart-rate flashing). On SSD-equipped models this is a non-issue. Probably that's why the sleep-LED has disappeared from those models too.

Sleep? Why does mine take so long to "wake up" when I lift the lid. Sometimes I have to wait close to a minute for the machine to "turn on/wake up". WTF?!?!?!??!

I distinctly remember the G4 MBP waking instantly upon opening up. It was ready for work by the time the lid got 1/4 the way upright. I would always make fun of the windows folks who had to sit there and wait for theirs to wake up.

I still use a 2006 white macbook, and it only takes a couple seconds to sleep, and couple seconds to wake up. Never had an issue. Pretty much as soon as I shut the lid, the light starts pulsing, and upon opening the lid, I can count 1001, 1002, and I'm up and working.

It shouldn't crash when sleeping. It powers down the RAM, and spins down the HDD during sleep. I think the only thing that runs is a little program to tell when you open the computer or move the mouse so it knows when to wake up again.

You'd be suprised though, about running out of power without realizing it. Three or four times I'd take my computer to school, put it to sleep, come home and it was absolutely dead (from 50% battery). Don't think I had anything unsaved, but keeping my current tabs open was great!

It crashes constantly, even if just the screen is asleep. When I try to wake it up, it restarts. I found that if I log into the guest user account before putting the computer asleep, it won't crash. Obviously, it's a software issue. I just haven't taken the time to reinstall OS X.

Personally, I've never had a complete battery drain on my computer, but I stay near a power outlet as much as possible.

I ran those and I'm down to 4 seconds to sleep 🙂 what does the stand by delay do?

I did some more research and found out that safe sleep has been around for a while. The support article by Apple made it sound as if it was a Mountain Lion feature.

This definitely is not normal. In my experience, all my Intel computers have woke up much faster than my G4 ever did.

It doesn't do anything. The same as the auto power off setting. It is a setting that only makes any sense if you have hibernation enabled.
It is some hybrid form that was first introduced with the Air some time ago. It goes into normal standby and after some standbytime of a few hours or days it shuts down completely. After that need restores from the sleepimage. They introduced it so they can claim 30 day standby time. It is a fraud really because if you don't use it so long just shut it down and if you don't, you don't actually save any battery.

Must have been some bug if you had to turn these options off, or maybe it doesn't really allow hibernationmode 0 without also turning off autopoweroff. In theory autopoweroff and standbydelay should be void without hibernation enabled as they depend on that.

I believe it is a bug, and so did the original poster (sorry forgot his handle so I can't give credit where it is due) of those terminal commands. The standby setting shouldn't affect anything when hybernatemode is set to zero, but that poster found that it did, which is why he suggested setting standby to zero and autopoweroff and standbydelay to the posted settings. In any case, setting them as posted above and again here:
sudo pmset -a hibernatemode 0
sudo rm /private/var/vm/sleepimage
sudo touch /private/var/vm/sleepimage
sudo chflags uchg /private/var/vm/sleepimage"
sudo pmset -a autopoweroff 0
sudo pmset -a standbydelay 72000
seems to work just fine. 😎 Just make sure you do not have any important not-saved data in an open app before you put the MBP to sleep - just in case you run out of battery power (safe computing practices). Or live on the bleeding edge if you must .... 🙄
A fix for the slow shutdown issue has been posted too, reducing the timeout settings from 20 secs to 1 or 2 secs. Another case of clever folks on MR fixing what Apple should have done .... 😎MR posters😎

OK so it's obvious that my Macbook Pro is full of bugs 😛 Hopefully once I have the time to reinstall Mac OS, it will run better.

Do you happen to have the link to the thread about reducing shutdown times? That's another gripe of mine!

 

[dusk007]

In my experience stuff like the slow shutdown times just keeps coming back. A clean install fixes that only for a very short time.

 

[dmahen]

I have a 2010 Macbook Pro, and this has been the behaviour since day 1! If I close the lid, it takes anywhere from 5-20 seconds until the light starts blinking!
I once had this little utility though, which keeps the RAM alive in sleep, and only writes to the HDD if i'm low on power.

Got it, mine is way overdue for a clean install. I'm just dreading it because it takes so much time to get my Mac setup the way I want. For instance, I will have to remember to re-run all of those Terminal commands to disable Safe Sleep. I have a list of Terminal hacks that I've done to my computer.

My Macbook Pro is going to sleep so fast now, I appreciate everyone's help!

Sorry, no link, but here are the commands, run them one by one in terminal.
All they do is shorten the time out from 20 to 1 sec.
Reboot and run repair permissions afterward just in case.

FixSlowShutdown
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.coreservices.appleevents.plist

sudo defaults write /System/Library/LaunchDaemons/com.apple.coreservices.appleevents ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.securityd ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder ExitTimeOut -int 1
sudo defaults write /System/Library/LaunchDaemons/com.apple.diskarbitrationd ExitTimeOut -int 1
sudo defaults write /System/Library/LaunchAgents/com.apple.coreservices.appleid.authentication ExitTimeOut -int 1

sudo launchctl load /System/Library/LaunchDaemons/com.apple.coreservices.appleevents.plist
