Macbook sleeps unexpectedly ?

So for the past two months my Macbook likes to sleep unexpectedly. This happens at all different intervals and may go 2-3 days with no problem and then have 2-3 days with problems. It may go to sleep while taking notes in class and I'll wake it up once and it's fine for the rest of class or I may continually have to wake it up every 20sec-3minutes and finally give up the battle.
This problem ONLY occurs when running on the battery. When the cpu comes back from sleep I notice the battery has an X on it for .2-2seconds and then displays like normal. I have swapped batteries with my gf and the same problem occurs. I have done the SMC reset and it still occurs. I really don't get why it works fine plugged into the the power adapter?
I was wondering if anyone can help me diagnose this? I'm hoping and praying it isn't the logic board because this is an otherwise great cpu that I hate to replace. What are the chances it could just be the battery connector sleep sensor? Errr it really has me frustrated because I take all my class notes on the laptop and I can't depend on it unless I happen to catch a seat next to a power outlet

It sounds like something is wrong with the battery and it's telling the computer it's dead so it goes to sleep. Try another battery and see if the issue persists.

  • Macbook late 2008 goes to sleep unexpectedly

    I've started having problems with my MacBook a few months ago. It goes to sleep unexpectedly and sometimes it takes me 30 min to take it out of that state. I've tried utilities like Caffeine to prevent the sleep mode but nothing seems to work. The temperature is fine, the fans work (4,000 RPM) but something is wrong. I read on a few pages that it could be linked to the sensor that actually detects that the lid is closed and automatically puts the MacBook to sleep. I wish I could at least prevent the sleep mode from triggering since I cannot use my mac for work at the moment. I simply cannot rely on it. Any ideas?

    Try a SMC reset which governs such things.

  • Macbook pro unexpectedly shut down after an usb plug in

    My macbook pro unexpectedly shut down after an usb plug in, and it won't turn back on. Please help!

    I have this problem also. The only way to get the computer to turn back on is to open the bottom and disconnect the battery then reconnect. I have found similar problems across the web, some people seem to fix the issue by resetting the SMC, but that doesn't do anything for me.

  • MBP sleeps unexpectedly

    My MBP is going to sleep and I don't want it to. (I want to leave EvoCam running.)

    The elgato/eyetv activity seems normal. I didn't find anything leading to a solution at the elgato/eyetv. It was informative; eyetv does interface with the OS to wake the computer to record something and then put it to sleep, but I didn't have anything scheduled to record anything for days. I've updated EyeTV and removed all scheduled recording to see if that helps.

    Doh!

  • Macbook sleeping when powered on

    Hi
    I have been noticing of late when my Macbook has been shutdown for a day or so, when I first power it up the sleep indicator light is lit and I have to press a button on the keyboard for it to start up. I am 100% sure the Macbook is shutdown and off before I close the lid so I am not sure why this is happening. Anyone else experienced this? This may have started occurring since installing the 10.4.7 update but may be just a coincidence.
    Macbook   Mac OS X (10.4.7)  

    it's normal. mine is the same when I turn on macbook, sleep light is lit little bit. then disappeared. it's probably recognized by system everytime restart. don't worry.

  • Sleeps Unexpectedly

    [posted this previously, but in general imac group - apologies]
    My G5 iMac goes to sleep unexpectedly, usually in the middle of something I don't want to interrupt. It does it
    -when I burn audio CDs from iTunes (hour long mp3s)
    -when I record audio input from an LP (but not when I record streaming audio from RealPlayer)
    -on some heavy web pages (Disney stuff, w/ a lot of flash & audio)...
    Pretty frustrating because it kills the tasks. Current theories are
    -cpu temperature
    -motherboard
    -reinstalling select system files
    Any ideas?

    I've probably already posted this to you somewhere else (the problem with multiple posts-more work and wasted time for us), but just in case;
    A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
    WAKE UP
    In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
    FILE CORRUPTION
    Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
    ENERGY SAVER
    If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
    -/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
    -/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
    -/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
    A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
    In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.
    As Tm311 said, make sure everything in Energy Saver is set to never.
    Cheers!

  • Imac stops-sleeps unexpectedly

    My G5 iMac goes to sleep unexpectedly, usually in the middle of something I don't want to interrupt. It does it
    -when I burn audio CDs from iTunes (hour long mp3s)
    -when I record audio input from an LP (but not when I record streaming audio from RealPlayer)
    -on some heavy web pages (Disney stuff, w/ a lot of flash & audio).
    Each time, it just dies - clicking brings it back as if it was coming out of sleep, but it interrupts whatever was happening previously.
    Thanks for help!

    Help is really appreciated. I dont want to reinstall the entire OS with all the software.
    Thanks!

    That kind of panic is usually caused by a memory fault, but you should start by removing the worthless Symantec "security" software.
    Remove the Norton/Symantec product by following the instructions on either of these pages:
    Uninstalling your Norton product for Mac
    Removing Symantec programs for Macintosh
    If you have a different version of the product, the procedure may be different. Back up all data before making any changes.

  • How do I stop my MacBook sleeping without a display

    Hi all,
    I have a MacBook Pro 13 joined up (alongside my PS3) to an Apple 24" LED Display (they are on a switcher - HD620).
    However, when I flip over to the HDMI input from the PS3, and therefore the MacBook Pro ceases to be using the 1920x1200 input to the display through MDP, it goes to sleep.
    This is a problem for me as I often have background tasks I need doing, or I might only be flicking over to the PS3 for a second or so and then switching back. I therefore want my Mac to keep on running.
    Can anyone suggest to me a way to keep my Mac running when there is no display connected - i.e. the lid is closed and the external display is effectively switched off?
    Thanks,
    Freddie

    Hi Freddie,
    You would need a third-party app or hack, neither of which I'd recommend (people have trouble with them). If you want to pursue it, google for it and you'll find said apps/hacks/issues.

  • Macbook sleeping when screen open and wakes on close

    I just repalced a busted screen on my Macbook 13"(white late early 2008) after it had falledn and broken the lcd screen.   Everything went fine and the parts all went back together perfectly and without any uncertainty with teh exception of the small magnet in the left side of the screen frame. 
    Now wehn I power on the Macbook the screen turns on for about three seconds then goes black. At first I thought it was not booting at all but after I walked away and came back to play with it I found that it finished booting up when the screen was closed. When I opened the screen I saw the desktop for a few seconds then the screen goes to sleep.  I can repeat this over and over all day long. 
    It looks like it is asleep when the screen is open but wakes up when the screen closes.  I know there is a Reed switch that controls this.  I moved the little magnet back and froth several times and any time it approaches the right area of the logic board the screen wakes up for a few seconds then goes black again. 
    Is there a reset that can be done to try and knock it out of this backwards mode?  (I have tried Command, Option, P, R while booting but no success)
    Is it plssible that I am just holding the magenet in the incorrect orientation?  (I've tried turning it a few different ways)
    Is it possible that the fall caused something to be damaged other than the screen?  (can't imagine a Reed switch going bad due to being bumped)
    Any advice would be great.  Thanks!
    Doug

    Try Resetting the System Management Controller (SMC)
    slowly starts back up
    How much free space on the startup disk?
    Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you always have a minimum of 15% free disk space.

  • Late 2011 Macbook Pro Unexpectedly Restarts

    My Macbook Pro has twice in two hours unexpectedly restarted it's self, both times I have been using Chrome. The crash report gives a different reason each time.
    MacBookPro8,2, Intel Core i7, 2.2 GHz, 8 GB
    I have attached both crash logs.
    As of right now I'm blaming Chrome. Any insight would be very appreciated.

    Stop using Chrome and use Safari. Also, consider uninstalling the following:
    Sophos AV software because it is not necessary. Restart after. Be sure you use their uninstaller or see:
    Uninstalling Software: The Basics
    Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash.  Applications may create preference files that are stored in the /Home/Library/Preferences/ folder.  Although they do nothing once you delete the associated application, they do take up some disk space.  If you want you can look for them in the above location and delete them, too.
    Some applications may install an uninstaller program that can be used to remove the application.  In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
    Some applications may install components in the /Home/Library/Applications Support/ folder.  You can also check there to see if the application has created a folder.  You can also delete the folder that's in the Applications Support folder.  Again, they don't do anything but take up disk space once the application is trashed.
    Some applications may install a startupitem or a Log In item.  Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder.  Log In Items are set in the Accounts preferences.  Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab.  Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
    Some software use startup daemons or agents that are a new feature of the OS.  Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
    If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term.  Unfortunately Spotlight will not look in certain folders by default.  You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
    Some applications install a receipt in the /Library/Receipts/ folder.  Usually with the same name as the program or the developer.  The item generally has a ".pkg" extension.  Be sure you also delete this item as some programs use it to determine if it's already installed.
    There are many utilities that can uninstall applications.  Here is a selection:
        1. AppZapper
        2. AppDelete
        3. Automaton
        4. Hazel
        5. AppCleaner
        6. CleanApp
        7. iTrash
        8. Amnesia
        9. Uninstaller
      10. Spring Cleaning

  • IMac goes to sleep unexpectedly, Finder issues with flash drives - related?

    My iMac falls asleep for no known reason, often in the middle of active use. (Similar problem recently described in thread with messageID=11829917.)
    Sleep onset is frequent but seems to vary based on both currently-running software and attached devices (particularly USB flash drives). It will almost always wake up when I hit the space bar afterward, but might sleep again within a minute or two, then not for an hour or more. The sleep occurs with little notice (brief stall of display, sometimes enough time to click on another app window and bring that forward before the screen goes dark), and 95% of the time the computer wakes up after hitting the spacebar. The other 5 % of the time the display reappears but the entire OS is frozen and usually requires unplugging the power cable. There are other symptoms in the Finder - more below. Once in a while the fan revs up like a WWII fighter plane taking off from a carrier, but this is unusual and all the really irritating stuff also happens without this symptom, which usually stops on its own. Immediately after reawakening error messages are displayed to report that flash drives were improperly disconnected (Tell me about it! This has been the case for several months whether the computer goes to sleep by itself or if I put it there manually.)
    The computer seems to go into sleep mode most frequently when not-particularly-demanding graphics (Photoshop Elements and Adobe Reader) and video (QuickTime Pro 7.6.4) apps are running. Turning these off makes nod-offs less frequent but doesn't stop it entirely. When video thumbnails are displayed in Finder windows a lot of time may be required to load the data and this often paralyzes everything else AND this also seems to be a trigger for a nod-off (i.e. QuickTime not necessary to make the computer choke). This is highly variable and some video clips load quickly (< 20 sec), while others take several minutes, and this doesn't necessarily correlate with file size.
    Another factor is whether flash drives are connected - these seem to make the nod-offs more frequent AND Finder regularly loses communication to these both while just sitting there and also in the middle of file transfers. A very early 250 MB drive (Lexar - vintage 2004) will always communicate, but different USB2-capable drives all are either unreliable (Lexar 8 GB and KData 4 GB both < 1 yr old) or apparently dead (Lexar 2 GB ~ 2 yr old). The failures may be damaging the drives - they are inconsistent-to-bad at communicating with my MacBook Pro. I know this sounds like the drives are at fault, but there are things which make me suspect the OS (both computers use the same version): 1) different flash drives display the same on-again-off-again behavior AND the 2) the 2 GB drive that hasn't communicated with my Macs in over a month has no trouble talking with my wife's WinXP computer. When communication isn't working with these drives, they do not show up in either Finder or Disk Utility. When the Mac-dead 2 GB Lexar is plugged into either computer and I launch Disk Utility, the initial scan for drives never finishes so I have to force quit. (When they are working, on the iMac the large drives only appear in Finder if I go to User and press Command-uparrow (to go up a directory layer) - in columns display mode nothing appears in the left-hand column.
    (The following describes a set of problems I've had a little longer and which may or may not be related):
    At times the Finder loses some but not all functions:
    1) Sometimes files in the Trash can't be ejected* even when all apps are turned off
    2) usually when problem 1) is observed, no keyboard commands work: nothing happens when pressing Command-W, Command-uparrow or Command-N to open a new window. Text typed will not be entered to change filenames (but this can still be done by typing the desired text in TextEdit, copying there and selecting and pasting with mouse commands.)
    <* I have downloaded an app for forcing file deletion, but haven't really needed it - the delete option and keyboard commands all return after shutdown and reboot, and there's usually enough annoying stuff going on by this time that that seems the best thing to do.>
    Things which I've tried to fix it with so far (not in this order):
    - blowing dust out of the back with canned air
    - checking temperatures - CPU/GPU showing 72/73, HD bay 51, etc.
    - fixing permissions from normal boot
    - boot from install disk and running extended hardware test (no problems found during scans repeated several times during the past month)
    - fixing permissions and running Disk First Aid from install disk boot
    - getting files off the hard drive (was as low as 3 GB free space, currently ~ 35 GB and climbing)
    - clearing PRAM
    - resetting system manager (name? - hold down power button when reconnecting power cable, etc.)
    - Power Saver display and computer auto sleep are shut off (both on "never" - I regularly put it to sleep manually)
    - virus scans (Clam XAV)
    I realize that this is a kitchen sink collection of symptoms, but these things may be related and if so, OS developers may want to be sure these problems are avoided in current versions. (Yes I will upgrade my OS soon...)

    Thanks for checking in, Miriam - sorry to get testy about it.
    The iMac's RAM is maxed out (2.5 GB)
    Yes, the system log does report overtemp message to Power management prior to shutdown (today's log at end of post)
    Where do I find normal temperatures for the system? What are the important parameters to watch and what sort of fixes are possible?
    iStat currently shows:
    HD 54° CPU 67° GPU 72° Incoming air 38° (???)
    HD bay 54° GPU ambient 71° opt drive 49°
    ==========================================
    Console.log was largely full of stuff about a bad flash drive I stuck in as a Hail Mary and failure of communication with a scanner (old HP, driver package installs a program which starts at launch which doesn't show up under Startup Items. Apparently the permission got mislaid, so I fixed permissions and this seems OK now. (Only included that because some of it shows up in System.log and it's not worth focusing on.)
    [That all said, there is a software/OS component to the problem and it is graphics-related. The other night I was looking at some flash videos in a series and one in particular repeatedly caused shutdown, while others played normally: domain = jebhost.com /youtube/list.php?q=Henry+8.o&Submit=GO "The Tricycle Thief" only played through once out of about six tries.]

  • Macbook sleeps with long delay and tons of system messages

    It takes my MacBook Pro a long time to go to sleep (4 minutes or more). During this time thousands of messages are produced in the System log.
    There are so many of them that some messages are discarded. Some of these messages:
    05/10/2014 16:31:08.000 kernel[0]: [0x445334a000, 0x2000]

    What do these messages mean?
    I have tried, without success, the following things:
    - reinstall the system
    - perform a disk verification
    - repair file permissions
    - boot in safe mode
    What I have not tried is a hardware check, because I couldn't. (Starting up with D pressed has no effect and starting up with option-D pressed initiates the check, but this is aborted because my machine doesn't support it.)
    The behavior takes place with hibernation, not with "unsafe sleep".
    Machine: MacBook Pro 15" mid-2014, 2.4 GHz Core i5, 8GB memory, with Mac OS 10.9.5.

    Thanks for the tip. I checked out the link. The issue is not that my log files are large but it's that log messages (the same message over and over again) are being constantly written to that Console application - I guess by syslogd - at a crazy rate per second which is causing the CPU to spike and causing my Free RAM to go from say 3GB to a few MB's within a matter of seconds. I actually can't find a log file on my system (via Spotlight search or Terminal "grep" searching) that has the hundreds and thousands of messages showing up in the Console log app. syslogd just gets "crazy" and pretty much takes over the CPU and depletes my computer free RAM when handling those:

  • Can't get my macbook to display on airplay after macbook sleeps

    When my macbook pro goes to sleep I can't establish my airplay connection without restarting my macbook.
    My macbook shows it's connected to airplay but win't disconnect. I try from the airplay menubar icon and from the display settings. I click disconnect and the menubar icon stays blue. I click switch to air display off in the display settings and it jumps back to airplay display on it's own. When I turn off wifi or turn it off on the apple TV, airplay goes away. When I turn wifi back on or turn on airplay on my apple TV, airplay reconnects or thinks it is connected but my macbook screen is not on the air display.
    I am using apple TV software v7.0.1 and Yosemite 10.10.1. I am using the extended desktop option with my apple TV.
    Any ideas how to get airplay to show again without having to restart my macbook?

    You need to go to System Preferences>Displays, and set Video Mirroring.  I think you've got it set to Shared Desktop.
