Much slower wake-up from sleep since upgrade to ML

Hello,


I am running Macbook Pro Retina and just upgraded to Mountain Lion. Everything is working fine except I find a much slower wake-up time when I open the lid.

On Original Lion the laptop was always waking up in less than 1 s. Now it's systematically more than 5.


I am wondering if anyone has a similar behavior and if this can be a ML issue?


I wish not to have to reinstall ML from scratch having to restore so many applications and settings...


I have tried PRAM reset but no help.


Anyone?


Thanks


Jeremy

MacBook Pro with Retina display, Mac OS X (10.7.4)

Having reinstalled my OS, after a TimeMachine Backup, I'm much happier. By avoiding installing the 2.0 2.0 update from the App Store, I now haven't had to change anything in Terminal, and my MBP runs perfectly.


I heard back from Apple – apparently autopoweroff is something that was introduced due to legislation?!


Anyway, they say they are aware there's an issue, and are looking into it...


While tweaking the auotpoweroff settings, whether turning it off or adding a delay, does help, I prefer avoiding the update. If Apple fix it, great, if not... well, I haven't seen any issues with my machine through not running the update.

@ Leodanger: if I unplug your MBP from the AC adaptor before opening the lid, the light on the front will illuminate fully as the machine enters a darkwake. If you now open the lid, you'll find the screen stays dark, and won't turn on for about 40 seconds....


Was even before update that caused all problems?


Any solution to fix without reinstalling OS?


Thanks

I saw your original post after having similar problems and associating it with me changing my computer (2011 Macbook Air 13in 256gb SSD i5 4gb), and it finally got on my nerves when my friend's macbook pro had start up that was about fourth of my start up time. I looked through the replies on this post, and though I don't have an answer to the problem, I saw some very helpful tips. Turning off Power Nap did not seem to change much, but disabling iCloud did improve my start up time greatly. I would suggest you do that if you don't use iCloud much. Unfortunately, I use iCloud a lot, and so that will work. I hope you find that suggestion helpful (even though this reply is very late). I will keep searching for a real answer, or a fix to the bug.

Chuck it my way. 😝


Seriously, if you've had that much trouble, and are frustrated enough to want to get rid of your MBP, you should try doing a disk repair. If that doesn't make any difference, do a clean install then do a disk repair.


I was an early poster in this thread with an '09 MP that had the slow wake problem after the upgrade to ML from Lion. The clean install fixed the problem. Later, my MP started to suffer from the creeping death hang on wake. A disk repair fixed that.


Good luck!

hi. thanks. i appreciate that.


are you suggesting a full disk wipe and re-installation of OS and software and customized settings etc etc?


unfortunately i have done disk repairs repeatedly and have done at least one fresh install and a whole bunch of other reinstalls short of a full disk wipe over the 3 years i have had this computer. when i have had to do a full fresh installation (which i have in fact done within the last four to six months) this has involves such an unbelievable amount of time and effort (we did a /manual/ migration of my data in order to not bring in corrupted info with an automated migration) - that i just don't have the time to do this again at this point.


plus, i have been /fighting/ with this computer on all sorts of issues similar to this wake from sleep problem literally since the first year of owning the machine. i went ahead and spent additional cash to put a full 8 GB of RAM in the machine at the 1 year mark hoping /that/ would fix the problem. then i thought finally getting a new battery and logic board under warranty would fix all these issues.


now at 3 years (and under warranty) i cannot even walk into the genius bar and get them to replace the wobbly keys that makes /typing/ on the device difficult!


this is not a pro level of performance IMHO.


i think i spent 1500 on the machine, upgraded to full max RAM and have all sorts of issues that supposedly are user related (i love how they always say "it depends" when you ask about reasonable battery life expectancy or there is some operator related reason why wake from sleep or battery drain is so funky...).


anyway, it would take an awful lot to get this returning mac user who was a big fan to be exceptionally leery of the mac product but i can't imagine spending big cash on another laptop for quite awhile and if i do i am going to be extremely worried that i am throwing my cash down the drain again.

I had issues with the machine always hibernating when I put it to sleep, which sounds like one of your problems. My problem was caused by defective RAM (from Crucial). Using Apple certified RAM fixed the problem.


Proper RAM won't fix wobbly keys. It might fix battery life issues, because it will make any machine misheave in some odd ways. Bad RAM causes all kinds of bad machine behavior.


Does your machine misbehave with the original RAM installed?

Apr 20, 2013 1:41 PM in response to broz

hi. what exactly is the difference between "hibernate" and "sleep"? do you have a 2009 and know for sure that your machine is suppposed to behave the same as my machine in terms of sleep?


i put the RAM in to try and prevent beachball hangs and slow response and overheating of power pack and underside of the computer case and the loud fan. the excessive battery drain, drain during sleep. slow wake from sleep and issues listed above have been in existence since i bought the computer.


adding RAM was a desperate attempt to get this "pro" line computer to perform better.



since then it has been an endless search regarding various suggestions related to "user caused" issues with answers from mac that state "it depends".


i finally got the battery replaced when it alerted as needing service and then i got the logic board replaced when the battery replacement indicated there were other problems.


NOW that i am able to actually use the computer off of the power charge i have been trying to determine what exactly the issues are with respect to waking from sleep or shutdown when i have it OFF POWER (i couldn't even use it off power for any period of time until i got the two replacements i listed) so NOW i am testing other issues that have been with the computer since i bought it.


it is totally ridiculous to be tracking problems with a 1500 dollar pro line computer that i added roughly 300 more RAM to. now you are suggesting the issue is the RAM!!


this is like a big joke and it takes a terribly bad experience to get a big time mac fan to hate the product like i do.


i don't want to be a wise guy but of course additional RAM is not going to fix wobbly keys that make it hard to type. I just wish MAC fixed the wobbly keys!!


asking me to bring this thing in to replace some of them (like i would do my tires one at a time or something) is so insulting it is like the icing on the cake for me on this one.


like i said, the amount of time spend troubleshooting problems with this computer has been absolutely extraordinary and the lack of seriousness with which mac is now standing behind their products is indicated by their (insulting) request to have me tell them which keys are bad before they will replace them WHILE UNDER WARRANTY.


the whole experiene with this machine is like a sick joke.


now i am going to test waking from sleep with the power cord connected and plugged in, while the power cord is connected and not plugged in and while the power cord is not connected to see what the battery drain is like and what wake from sleep is like? then i should be explording a new suggestion as to whether the RAM i put in is causing this? i would imagine mac would have picked this up when they looked at it four or five times in 3 years.


this thing should start like my toyota and not like some piece of junk and it should run smooth on the road and not wobbly all over the place and i should be able to get decent mileage out of it.


this machine doesn't pass even these reasonable tests

Apr 20, 2013 5:08 PM in response to hotwheels22

Defective RAM could cause most of the issues you state.


Put diesel in your gasoline powerd Toyota will cause you a great deal of problems. Jump starting your Toyota with the polarity reversed will cause you a great deal of problems. Don't tell me about your Toyota! There are plenty of people with Toyota troubles. Stick with the real reason for your issues with your Mac.

You state: "what exactly is the difference between "hibernate" and "sleep"? do you have a 2009 and know for sure that your machine is suppposed to behave the same as my machine in terms of sleep?"

Yes, I am ABSOLUTELY CERTAIN that my machine is supposed to behave EXACTLY like your machine in terms of sleep!


Defective RAM will cause almost every system in a computer to behave poorly. In my case, it was hibernate instead of sleep when I closed the lid. Hibernate is when the machine writes its current state to disk before shutting down. Sleep only stores the current state in RAM, such that it starts quickly when you open the lid. Starting from hibernate requires pressing the power key, and waiting for the machine to start up as it reads from the hibernate file on disk.


All of your problems, every single one of your problems, could EASILY be caused by defective RAM (excluding the keys).


I have two suggestions.


1: Take your additional RAM sticks out and put the original sticks in and see if it performs properly. If it does, you can be fairly certain the RAM is defective. Replace it with new, high quality RAM. It is NOT UNCOMMON for RAM to be defective. I've seen it a half dozen times in my computer career, and more frequently in the past few years.


2: Sell your MacBook Pro, but keep your additional RAM sticks. Put them in your new Dell, HP, Asus or whatever you buy. Enjoy system crashes, failure to sleep, failure to connect to the network, high battery usage, excessive CPU usage, and extremely slow performance. Maybe you'll be lucky and get a keyboad without wobbly keys.

hi.


since this thread is about problems with "wake from sleep" the point i have tried to make in this thread is that since buying a mid-2009 computer i have been totally confused as to how this machine is supposed to behave with respect to waking from sleep and how it is supposed to behave with respect to battery drain. both of these issues have been endless problems for me with this machine (out of the box). so i dealt with the battery issue by NEVER taking it off of power. this means that i /never/ dealt with some of the subtleties described on this thread in terms of keeping the power plugged in and waking from sleep, or specifically taking it off power and then waking from sleep etc, etc, etc. there are almost 41,000 views of this thread and perhaps i have missed it but i haven't seen a single reference to definitive documentation from mac on this problem and but you want to attribute all my issues to non-mac RAM.


the fact is that the way i have always dealt with the wake from sleep issues is by just ignoring them and not expecting the computer to wake with any kind of /reason/ or /pattern/ or /speed/.


also, you specifically mention "hibernate" and "sleep" as two distinct behaviors in your response - and i would be interested in seeing documentation about how these two behaviors are distinct and which machines do in fact have a hibernate mode. my understanding in reading documentation is that my machine does not have "hibernate" mode but since i can't even get sleep mode to behave normally i am not sure how this really matters much.


i will of course take your comments under consideration (and i appreciate them) however, there are a couple of things we should consider.


first as i explained i purchased the RAM specifically to /prevent/ some of the problems i listed. so it seems to me to be hard to reason that now the RAM is the cause of all the problems. also the computer has been in for /numerous/ full tests by mac so presumably you are indicating that mac missed this problem with the non-mac software or that they are simply telling me the machine is ok when it is not? or maybe they are just testing their hardware and not the non-mac RAM? or perhaps their is a problem with their testing regime? or maybe there is a problem in what gets tested and how they report to the customer? or maybe since having it in before warranty expiry (and finally getting a new battery and a new logic board) that the RAM has gone bad /after/ this final set of tests when they once /again/ gave me the "all clear" just three months ago?


i mean, granted it /is/ in fact possible that this aftermarket RAM is causing some kind of problems but the point i am trying to make is that i cannot even do something as simple as getting the manufacturer to replace my KEYS without getting some kind of run around asking me which keys specifically i need replaced.


after going through everything i have gone through with this machine - and to now be trying to tackle the outstandng issue of the odd startup indicated in this thread - this is absolutely ridiculous to me. so the analogy was intended to point out that /not/ fixing something as mission critical as keyboard keys is very problematic for someone that has to spend 2 grand to buy a "pro" level computer that they need to use reliably on a daily basis.


i mean, if i can't /type/ on it with any precision and i can't even get it to wake with any speed all the rest in operating the machine seem like they are just all apiece with this particular model of laptop or this particular machine.


attributing most of this to aftermarket RAM that was not diagnosed by mac seems like an outside shot at the very best but i'll post back if this ends up being a major or even a contributing factor.

I have seen hibernate referred to as hibernate and also Safe Sleep. Apple calls it safe sleep in its user docs, and hibernate in various develpoer related docs.

http://support.apple.com/kb/PH11096


This article describes the process a bit better, but refers to machines newer than yours (and mine).

Read this for details on "Computer Sleep", the term Apple uses for regular sleep when you close the lid:

http://support.apple.com/kb/HT2412


They define Safe Sleep as "In the event the battery becomes completely depleted while the computer is asleep, the computer will shut down." Before it shuts down, it writes the current state to disk. That would include open applications, files, windows etc. It's actually good practice to let you battery run all the way down periodically to cycle the battery, but that's another discussion.


In my case, my battery was not depleted AND the power cord was attached. There is no excuse whatsoever for the machine to enter Safe Sleep, when regular Sleep was called for. I fussed with my machine for a couple weeks with every tweak I could find in these discussion boards and elsewhere. No help. I didn't even consider defective RAM until I just ran out of ideas. That was the last change I made before the machine started to misbehave. I contacted Crucial who gave me the URL for a couple memory testing applications and also asked me to try replacing their RAM with the original RAM that came with the machine. The memory testing utilities showed the RAM was "just fine." Memory testing utilities are limited in scope, and I was not willing to pay for a better utility. Also, to fully test RAM, it can take a week. You start the utility, and let it run uninterrupted for a day, or a week. Sheesh! I don't have time for that. The trivial RAM tests take a few minutes, but might not discover the problems.


I then replaced RAM in one memory slot and tested sleep. It did the sleep thing correctly, waking up in a few seconds (4 seconds). I replaced that proven working memory with the other third party stick. Aha! This stick of RAM caused the hibernate instead of sleep. Instead of taking 4 seconds to start, it took 45 seconds, with the progress bar and all. In fact, it did not start when I opened the lid. I had to press the power button.

Conclusion: one stick of RAM from Crucial was good, the other defective.

I got an RMA from Crucial and sent back the defective RAM and got new RAM when they received my defective RAM. The replacement RAM has worked fine.


All of that said (typed), I am by no means certain that your machine has defective RAM. I am reasonably sure that you have not considered that as a possibility.


BTW, my mid 2009 MacBook Pro has been trouble free (excluding the above mentioned RAM problems). I bought AppleCare when I bought the machine and never needed it.


As for the keyboard keys, I don't get your argument there. Do you want your defective keys replaced or not? These keys are modular. They're not going to replace the whole keyboard for just a couple keys. If one of your car headlights fails, they're not going to replace both headlights.

hi. i guess i have enumerated the earlier problems with this 13" MBP well enough so i won't repeat them.


the problem for me now is that to now be dealing with this kind of restart and/or wake from sleep problem after having had to ignore it while i had to hack through all the other issues with this machine is extremely unpleasant. in the past the various issues had always been basically swept under the rug or attributed to user error in some way. when i finally got an actual error message someone finally started to do something (i suppose they absolutely had to since the machine was reporting to the owner that there was a problem...).


so the point i am making about the keyboard keys is that when i went in to ask them to replace the keys while under warranty (many of the /individual/ keys on the keyboard are wobbly which makes typing on the device difficult) - i was asked to enumerate which /particular/ keys were a problem. to me this is like adding insult to injury when you consider the sum total of the problems with this machine. and the idea here is that to replace /some/ of the keys that are exhibiting failure and that makes using the device difficult, while leaving the other keys which are not yet exhibiting failure (but presumably will be exhibiting failure in the near future) is indicative of how this machine has been handled from a customer service perspective. and this is not how i remember being treated back in the day when i first started using macs and this is quite disappointing.


so to now be finally in a position to tackle less mission critical issues such as the speed the machine starts up - and to be going down some wormhole three years into owning the device - where i am reading a two hundred post thread trying to figure out why it wakes to black screen or takes an eternity to start up is similarly disappointing. i mean, your point about ram may be worth pursuing but given the myriad of issues with this machine you would have thought mac technicians would have caught this or the mac genius bar folks would have taken the compaints serious enough to resolve things earlier.


so, assuming we have cleared up the keys/keyboard and the other issues - i am curious as to why you indicate the second link does not pertain to the 13" 2009 MBP. i mean, i am interested in documentation that describes how hibernate/safe sleep etc is supposed to behave or how this "functionality" does not actually pertain to the 2009 13" MBP. i ask because i am pretty sure that somewhere earlier in this thread or somewhere in my research i found out that this behavior is not supposed to be exhibited on my machine for one reason or another. i personally think there has been some kind of botched implementation related to the graphics card or the firmware or whatever in this machine as it relates to these issues because i have always had a rough time with getting this machine to wake.


i suppose for arguments sake one could attribute this to bad RAM but again since i bought the RAM to solve various problems that affected the machine in a global way - and since i can't get something as simple as full key replacement under warranty - i am having a hard time imagining how the device itself is not the culprit for everything at the end of the day. and in any case it would be nice to get some kind of definitive documentation as to how mac imagines my actual machine is supposed to be behaving under various conditions related to startup instead of always getting an answer related to performance or battery life that is some version of "it depends"...
