Random shutdown problems, MBL late 2011

Hi, I have a late 2011 MBP 13". I bought new mushkin 8gb ram (2x4gb), 10600 pc3. When i switch out the rams, macbook randomly shuts down sometimes. At the same time, if I mix up the rams, put one of the 4gb sticks in and leave an original 2gb stick in their, it works fine? Why is this happening?
This is the new ram i bought.

That's excellent RAM and should work well in your model. I'm not sure why, when you mix the RAM, your machine doesn't crash nor why, with both sticks installed, your computer crashes. It could be that you've one bad stick of the new RAM or that you somehow damaged the DIMM socket when you installed the RAM.
Try, with both new modules installed, to run Rember - this will help eliminate one or more sticks as damaged.

  • Are the replacement Heatsinks fixing people's Random Shutdown problems?

    Is the replacement heatsink (the shorter one) still the method of choice from Apple for fixing Random Shutdown problems?
    Is it working for people who've had it done recently?

    Does this max out the CPU?
    Yes. People who advocate this are testing to see if it's possible to induce a "random" shut down.
    Why would anyone want to do that?
    Good question. I've seen two reasons put forward: (a) It's better to make it happen now yourself rather let it strike out of the blue at some later date (and if running this test doesn't induce RSDs you can feel confident that your computer is probably immune); (b) If you take your MacBook to an Apple Store it could be useful for demonstrating to an Apple "genius" that your computer has the problem, especially if your shutdowns are infrequent.
    (personally, I don't agree with (a))

  • Random shutdown problem on G5 dual 2.3 GHz w/OS 10.4.7

    Hello,
    I’m using a dual 2.3 GHz G5, and it’s been working flawlessly since I bought it about a year ago. Until yesterday, I was running OS 10.4.5. Yesterday I upgraded to 10.4.7, and as soon as I booted up after the install, I started having a maddening problem with my computer randomly shutting down. (Not sleeping, but a complete power down.)
    At first, the shutdown would happen immediately after powering up; my computer wouldn’t even make it to the blue progress bar. I zapped the PRAM and tried something I found online about unplugging the computer for 15 seconds, then plugging it back in. It now boots up, and I can log in, but the computer still shuts down randomly.
    There seems to be no pattern to the shutdowns. I tried taxing the processor by opening and resampling huge Photoshop files while lots of other apps were open, and things were fine. Then it would conk out while I was composing an email.
    I’ve heard of this random shutdown problem affecting Macbooks, but I have yet to find anything about G5 towers and OS 10.4.7. Does anyone have any info/advice?
    Many thanks.

    G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HD

    Thanks for the advice. I did check the system.log in Console and found the following altert:
    PMU FORCED SHUTDOWN, CAUSE = -122
    Now, since my computer is just over a year old, and since this problem happened immediately after applying the 10.4.7 OS update, I found it hard to believe that my hardware could be responsible. After 2 days of troubleshooting, I was stumped; after a 2-hour service call, so was Apple tech support. I ended up doing an archive and install back down to 10.4.5, and all is well.
    I tested this issue on other machines running 10.4.7 and had no problems. It seems that the following specific combination of elements triggered the problem:
    • PowerMac G5 dual 2.3 GHz (dual 1.8 machines did not exhibit the same problem)
    • OS 10.4.7
    • Logging in with Open Directory/Active Directory mobile profiles
    • iTunes 7
    Bottom line: if you’re using a dual 2.3 GHz PowerMac with mobile OD/AD profiles, do not update to 10.4.7, and steer clear of iTunes 7, at least until there is a patch update available.
    (And Apple wants to be taken seriously in the enterprise market?)

  • Random Shutdown Problem Fixed (for now)

    I experienced the same random shutdown problems/symptoms with my MacBook that have been extensively described in this forum and elsewhere. I sent it back for repair under AppleCare and it was returned in 3 days. It has been running now for 4 days with no problems and far cooler and quieter (the fan rarely comes on) than it was before. The repair sheet indicates that the heat sink and heat assembly unit were replaced.
    I'll keep my fingers crossed, but at least in my case and perhaps others, the problem may simply have to do with the thermal contact with the heat sink going bad and the processor simply shuts down due to overheating.
    MacBook 2 GHz   Mac OS X (10.4.7)  

    Followup:
    They told me something interesting at my Mac Retailer. They have had two other machines brought in doing the same thing. They tried new logic boards with no success, they tried new thermal assemblies with no luck, new ram - nothing seemed to solve the problem.
    What they finnally did was replace the Hard Drive - they tell me this has fixed the problem. Now I don't know if that is what they'll do to mine. The other two machines had the 60gb drives - mine is a 100gb, but we'll see. From all I have heard, this doesn't make a lot of sense to me. Anyway, we'll see what happens.
    Anyone else hear anything about replacing the hard drive?

  • Random Shutdown Problem

    Hello I started seeing the random shutdown problem around 6 weeks ago. The problem occurs every once in a while usually around the first 5 minutes of the unit booting up. When the system powers down I will try to bring it back up but it just powers down within about 15-30 seconds again. So I wait a little while about a minute, sometimes removing the battery for 30 seconds and the system will come back fine. The random shutdown has happened probably about a dozen times within the last 6 weeks. It's not causing a real big headache yet. I didn't purchase Applecare as I never do because I rarely keep a laptop for more than a year. My question is has anyone got their unit fixed what was the culprit. I've sent my unit in already once due to receiving a spinning pinwheel 90% of the time. They gutted the unit and sent it back and it has been working fine other than the RSD. I've been waiting things out to see if there is going to be a software fix for the RSD. Any tips recommendations are appreciated.

    My question is has anyone got their unit
    fixed what was the culprit.
    Mine has not had the problem recur after replacing the heat sink a month ago. Currently Apple seems to be replacing both logic board and heat sink with a new design for the combination.

    and it has been working fine other than the RSD. I've

    General opinion would say it's a hardware problem; there won't be a software fix.
    I'd say you should send in it for repair.

  • Problems with Late 2011 MBP (catalog corrupt, won't boot from USB/CD)

    Hello,
    I have had some problems with my Late 2011 MBP running OSX 10.8.x (latest update)
    I was using Safari when suddenly my screen froze. It has happened a couple of times before but it usually is either: 1.) a black screen for 5 seconds while nothing works responds and then it continues work like nothing happened, or 2.) just a freeze for a moment which goes away within a few seconds. I have visited the official service and they found nothing wrong with my laptop and said that it may have been just random occurrence. This time it froze and as I waited the fans went crazy and had no other option but to shut down from the power button. Later, when I wanted to boot up, it gets to the Apple logo, the circle spins and the small bar below appears and after a second or two, it disappears and then the computer shuts down. I went to recovery mode and used disk utility to verify and repair the problem (which only works to find out the problem, not to fix it, thanks anyway apple) Heres what it showed:

    I tried to boot DiskWarrior from a USB and a CD, after pushing enter in the bootable device's screen, I get a continuous loop of 3 beeps and I can't boot from either of the mediums.
    I also tried the Single-user mode (Command-s when booting) and the /sbin/fsck -fy said that my HD is not completely verifiable. Also, 3/4 of the files mentioned in disk utility are also mentioned in this process, with errors as forrows: keys out of order, invalid index key, invalid extent entries (7 times), incorrect block counts, number of links and incorrect sizes for the foretold files and invalid catalog record type.
    The reason why I'm not doing a clean install is that the last few days I've been in the process of deleting unnecessary items on my laptop so I could make a back-up (as for some reason, Time Machine is awfully slow and a new 600 gb backup would take and enormous amount of time, but that's a problem for another day) and as I had not yet reached the backing up part, my data is locked on this (possibly) corrupt HD. How should I advance and what steps should I take?
    My first and most important mission would be to get back into my OS to make a back-up. Then I'd deal with the "not being able to boot form USB nor CD" and the TM problem.
    Thank you all in advance,
    Martin

    Before you even start, consider that there may be no Windows 7 driver support for some of the hardware in your laptop. You won't know which hardware devices and functions are unsupported until you find out the hard way. In some cases, a driver conflict could cripple your computer.
    Like most OEMS, Toshiba pre-installs Windows 8 to boot with EFI on a GPT hard drive. Your Windows 7 install disc, on the other hand, most likely boots with a BIOS from an MBR. Therefore, your Windows 7 disc will not boot your computer.
    You would need to start by performing a low-level format of your hard drive. This completely erases the disc and its metadata. Then you could boot from your Windows installation disc and try to install Windows 7. How successful you will be depends on driver support.
    All things considered, you should stay with Windows 8. Next time, more research before you buy.

  • Have any T430x users had random shutdown problems?

    like this one with the T400x model:
    T400s random shutdowns - Lenovo Community
    If not I'll buy a new one, otherwise I'll buy another brand. Thanks!

    Have you run all the newest updates at the new Lenovo update site.  It is up and running and took my computer a while to update including a new bios.
    This helps but will/can make it worst for a while.
    My Take:
    If you laptop is new OR you have just installed a good bit of software OR did anything to move alot of files around on your drive it will take time for Vista to re index the files.  Being that the processor is slow it will suck up resources that are required for the touchpad or even the keyboard.  Mine would even freeze the keyboard and you could type and nothing would happen and then all of a sudden everything you typed pops up on the screen.
    I have found that when ever you "upset" the indexing it is best to just leave your computer alone and let it do it's thing.  You will see alot of hard drive and processor activity.  After this stops, all is well and you should not have any more problems.
    This is my opinion on what is happening and I have noticed the same on all three of my X301 units one with normal hard drive and one with 80gb SSD and 128gb SSD.  Basically the slower processor is fine 90% of the time but seems to bog down a bit when asked to do too much.
    Try this and see.  Leave you laptop up and running for several hours, make sure it is set to not go to sleep and come back and see if it does not make a difference.

  • Random shutdown problem after replacement of new MB

    i got the replacement of my MB one month ago due to the random shut down problem. the symptom before the replacement was not only random shut down but also that the MB could not be turned on once a while.
    now it's been one month after i got the replacement from apple store, there is no randon shutdown at all, but when i got up this morning, i couldn't turn it on. i tried several times, but it just turned out to be dead. any suggestion about what i'm supposed to do? shall i ask for a refund or a replacement? i'm just afraid of that i would get a defect model again.

    thanks for both replies.
    i usually close the MB when the shutdown is completed, i know the shutdown won't be completed if i close it right after i shut it down.
    and also, i got a whole new mb as a replacement from apple store rather than having it repared and just the logical board replaced. and it's really weird, since it was said the new logical board doesn't have whatsoever problem. i also read some news on tuaw or infiniteloop (i forgot which one it is), the RSS is not really caused by the faulty logical board, it was the heat sink melt by the high temperature coming from the intel processor which shortcut the circuits around it. now i'm totally desperated. it looks like unless apple drops the stupid intel chip, otherwise the RSS will never go ever.

  • Random Shutdown Problem (External HD problem?)

    I've had a problem that's been getting worse recently. My MacBook Pro will freeze up, and a multi-language "you need to shut-down" message will cover the screen at seemingly random times. I've started to notice that this only happens when I'm using iTunes. I have a good amount of music, and it's all on my external hard-drive. I think this may play a part in the error, but I can't tell anything besides that. It's happened after my external HD was asleep and I clicked on a song to play it, and its also happened when my external was awake and playing my music. Also, it happened when I just closed iTunes. To resolve it I have to do a hard reboot.
    Any possible solutions? I'm a student, and I don't want it to happen when I'm in the middle of a paper or other projects.

    Turns out it is what they call a kernel panic.
    http://en.wikipedia.org/wiki/Kernel_panic
    http://docs.info.apple.com/article.html?artnum=106227
    Unfortunately they don't have much to say as for fixing it...
    Looks like I'll have to make a trip to the Apple store.

  • Pro Random Shutdown problem?

    So we bought a 15" Pro and it has this odd problem of just randomly shutting down. The battery has power in it and most of the time it is plugged into the wall anyway. Sometimes music is playing or I am even actily using teh laptop and then it just shutts down and I have to reboot. I know I will have to take it in for repairs and/or replacement, but I was wondering if anyone else has heard of or experienced this problem and have any idea what would cause such an issue?

    The problem you are describing could be a bad battery. You should check to see if your battery is part of the recall (https://support.apple.com/macbookpro15/batteryexchange/). If it is...there's your problem.
    If it's not, it still could be the battery, but you should try resetting the PMU first (http://docs.info.apple.com/article.html?artnum=303319). If that doesn't work, call AppleCare and ask for a replacement battery...
    Lots of folks on these boards have described similar experiences....try using the "Search Discussions" feature next time...

  • Is random shutdown a problem on newly purchased MBs as well?

    I am considering buying a couple of macbooks for my kids, but am troubled by all these reports of the random shutdown problem. Has anyone experienced this problem on macbooks purchased since say mid-August, or is it only on the original factory run? i.e. I am wondering if Apple has figured out the hardware problem and quietly fixed it? The alternative is a Fujitsu laptop (which I am typing on now--have had it for two years and it's great but my kids like the macbook). Any feedback from newer macbook owners would be appreciated. Thanks.

    I'm not a new Macbook owner but certainly read this forum enough to know that the random shutdown problem isn't isolated to specific dates of manufacture. Those who are affected have machines ranging from the earliest to the most recent.
    That said, if you search around here, you'll also read again and again that the number of people affected is very small. There has been a figure of 10% thrown around, which isn't exactly scientific in its basis.
    Buy the machines. Your kids will love you, you'll love yourself and all will be right with the world. Apple isn't going to just let this thing continue. When they find a lasting fix, they'll implement it somehow, either through a recall or on a case by case basis. The benefits of owning a Macintosh over a PC really do far outweigh the potential that one could be stricken with a problem that will soon be fixed.
    Then again, you may never have the problem at all. I have not and have been using this one since late May/early June.

  • Problems with random shutdown after replacing a swollen battery

    Hello all,
    Perhaps one of you can help with this issue.
    I'm using a Macbook Pro 17" mid-2007 model. A few months ago, the power disconnected from the machine when the battery had already run down and the machine did a hard shutdown. When I booted it back up there were serious problems with the display. Eventually it stopped working altogether. I took it for service and it was determined to by the NVIDIA graphics processor problem, so Apple replaced my motherboard.
    When I got the machine back from servicing, there was a rattle in the right fan that gradually got worse. After a while the touchpad button stopped depressing in the center. I also experienced several random shutdowns while operating on battery power. I learned about the swelling battery issue with macbooks and ordered a replacement. By the time the replacement battery arrived my original battery was quite swollen. I'm concerned that the swelling battery may have warped the case a bit, leading to the fan noise.
    I have now replaced the battery, but I'm still experiencing random shutdowns after 20+ minutes of use on battery power. I have done the RSS tests that were recommended in other forums and there doesn't seem to be any random shutdown problems when I'm plugged in -- only under battery power. My understanding is that a swelling battery can sometimes cause the battery to disengage from the electrical contacts on the MB, causing a sudden shutdown. I'm wondering why the problem is persisting now with a new battery? After one random shutdown, I tried to power up again using the battery, while pushing the battery into place at various angles, but I couldn't find any angle that would give power to the machine. The fan noise is also still present.
    Can anyone offer an explanation or advise on any methods to overcome these random shutdowns? I have checked the console and the machine isn't registering any error when it shuts down, although when it restarts it says "DirectoryService[35] Improper shutdown detected"

    Yep, it is video (or: or audio for video) so unless you're sure you need it (because you work or will work with the DVC Pro HD video/audio codec), you can remove the plug from its' folder and put it in your documents folder (don't trash it, I have no idea if it is necessary for non-DVC Pro HD users to have it installed too).
    The WWW is littered with posts from people encountering bugs and crashreports with DVCPROHDAudio.plugin as the main suspect. Most of those posts seem to be from video people rather than audio folks.
    http://www.google.nl/search?q=DVCPROHDAudio.plugin&ie=utf-8&oe=utf-8&aq=t&rls=or g.mozilla:en-US:official&client=firefox-a
    But, if you get crashes and you see this one mentioned in the report, disable it, restart, and see if the problem's gone.

  • Will the console log show a history of random shutdowns?

    My macbook has suddenly started the random shutdown problem. It started a couple of days ago, I'd had no problems up until then. At one point today it was shutting down immediately on waking from sleep, and then would only stay on for about two minutes with the fans racing before, bang, off it would go. I left it alone in exasperation, then returned to try again, and this time it lasted around an hour before shutting down repeatedly again. I will need to take it home to the UK to my local Apple service centre and I am worried that if it doesn't actually shut down in front of them when they have it they will tell me there is no problem and won't repair it. I know that this macbook has the RSS issue now but it really is random, so can I prove it from the console log? I looked through this just now and of course most of it means nothing to me but I did notice that there was a line saying "cause of last shutdown -72" occuring many times since this started. Does anyone know what this refers to and will it show that the problem is definitely happening?

    What does the holding the button down trick do?
    From the Apple article I referenced in your earlier thread:
    "If your MacBook is in a state where it will not remain on long enough to install the update, wait for the issue to reproduce itself. Once the MacBook has turned itself off, turn the computer on the by holding the power button down. Keep the button down until you hear a single long tone. Once you hear the tone you can release the button, install the recommended updates, and restart as you would expect."
    Allegedly, this throttles the CPU to 1 GHz.
    And I am slightly worried that a2dox says that the
    problem returned even after the repair..!
    Different experiences for different people, during the period when Apple had not yet figured out the problem. Their contract repair facility was doing different repairs, some getting heat sink replacements, some logic board replacements, some both, and, later, some a differently designed heat sink. When one of those repairs didn't fix the problem, they would do another.

  • K9N Platinum: CPU upgrade = Random shutdowns..

    I just installed a new AMD Athlon 64 X2 3800+ EE in my MSI K9N Platinum motherboard (MS-7250 v1.0, the 070 model according to the box). I had updated the BIOS to version 1.7 before installing the CPU. Anyhow, I got the CPU installed and it seemed to be running fine. Until I started playing my games. Upon playing fifteen (!!!) minutes of Day of Defeat, the system completely turned off. COMPLETELY. No error messages. I check core temp's log to make sure the CPU wasnt overheating; it wasnt. The max temp was 38C on one of the cores. Just to make sure the CPU wasnt the problem, I ran two instances of prime95 for 5 hours and there were no calculation errors whatsoever. I also ran 3-4 loops of SuperPi, using the 32M test. No errors.
    I have come to the conclusion that it must be the motherboard, and possibly it does not like the CPU. Or else it is having the same random shutdown problems as many other K9N Platinum/Ultra boards are experiencing. From what i have read, this issue only relates to boards that are 040, 050, or 060 models. I have a 070 model, and I AM GETTING THIS PROBLEM!!

    well, i know that ACPI has to do with power saving features.
    http://en.wikipedia.org/wiki/ACPI
    and HPET also has something to do with CPUs
    http://en.wikipedia.org/wiki/HPET
    and MCP55 is the nortbridge.
    so i suppose i can conclude that it protects from overvoltage or promotes more power-saving?  i dunno i really dont care as long as my PC works now, 

  • Random Shutdown in 2010 for a 2006 Macbook

    Hello-
    I have a 2006 Macbook 1.83 GHz processor and I never had the whole random shutdown problem previously... it burned through batteries like nothing and I was about to install my third hard drive, but no random shutdown problems. Well, now I have it...
    Anyway, it is out of warranty, obviously.
    1) Will Apple still replace the heatsink, since it was defective even though I am out of warranty?
    2) If not, does anyone know if by replacing the heatsink that should fix the problem?
    Thanks

    Sure Apple will replace the heat sync. At a price. I may be something else though. It might be full if dust after all these years. You could try putting a vacuum cleaner over the in vent and give it a good sucking. Worked for a friend of mine...
