Macbook air (11", mid 2011) turns off randomly

My macbook air 11" (mid 2011) turns off randomly. Sometimes, in the middle of something a black screen. After a few seconds it starts up again, on using a key. It restarts in the application I worked on before. Strange!

Do you have put hard drive to sleep when possible checked? Try unchecking it.Have you tried repairing permissions in utilities? You could also do a pram reset. Command/Option/P/R keys at startup for three chimes.

  • Mac book pro mid 2012 turn off randomly

    when not plugged in my mid 2012 mac book pro just turns off randomly and I just replaced the battery a month ago the old battery gave me the same problem and the new one was fine until  about 2 weeks ago now it just shuts off randomly and I have no idea why because the battery has only 36 cycles on it

    I have made a strange observation too  I decided to clean out the dust and once the bottom was off I propped the computer up with pens so it was not touching the desk and turned it on but the computer has not shut off without warning  anymore

  • MacBook Air (Late 2010) keeps shutting off randomly, sometimes when computer is tilted or moved

    Hi all,
    I have a Late 2010 13-inch MacBook Air. I've had it pretty much since they started selling them at the Apple Store, or maybe a few months afterward. For probably a few years I had only used it once in a while, since I had a Windows laptop for work. Since this past December I have exclusively been using my MacBook Air, I have since given away the Windows computer.
    Recently it has started shutting off randomly while I'm using it. I've tried resetting the PVRAM and the thing that manages how the power/screen works (I forget what its called), and that hasn't worked. I'll try to turn it back on again after it has shut off, and it sometimes doesn't come back on unless I tilt it a little bit. Does anyone know what could be causing this issue? Is it something I can probably fix, or should I take it to the Apple Store? Thanks for any and all feedback.

    Since the PRAM and SMC reset didn't work and your screen only seems to work when the screen is tilted at a specific angle, it might be a hardware problem. If you're near an Apple Store, you should make an appointment at the Genius Bar to have someone look at it: http://concierge.apple.com/reservation/us/en/techsupport/

  • Is it possible that my macbook air's fan is turned off?

    Hi everyone, I have a macbook air and I feel like the fan is not working because everytime I use it, it gets really hot and I don't know why this happens. That's why I'm asking if my fan is turned off..

    Resetting SMC may help. Try it.
    Reset SMC.     http://support.apple.com/kb/HT3964

  • Macbook air's fan not turning off and it will not sleep when the lid is closed?

    I downloaded OS X Mavericks yesterday.The fan will not turn off. It runs whenever i turn on the computer. The computer does  not turn off when i close the lid, and the fan still runs. There is also no battery icon anymore on my home screen. Is this just a bug with Mavericks? My computer is a mid 2012 edition.

  • MacBook Air 11" Mid 2011 (Fan & CPU Usage & Kernel_task)

    Hello everyone.
    I have a small problem with my Mac which is about its fan noise and CPU usage.
    It was running FLAWLESSLY until like last couple of days after OS update where I started to notice really high CPU and Fan usage.
    But first, system specification:
    1.6 Ghz Intel Core i5 Processor
    4GB 1333 MHz DDR3 Memory
    Intel HD Graphics 3000 384 MB Graphics Card
    Mac OS X Lion 10.7.5
    128GB SSD Storage
    For some reason my MacBook Air started to have these "high intensity work" moments when a process called "Kernel_task" started to eat up to 600% of the CPU !
    Now I can imagine it's just a software issue since it started to occur after I updated my OS via Software Application and my Flash Player and the rest of my software is up-to-date too but has any of you had this problem before ?
    I do not play on my MacBook Air, there are only two things I do - I use Safari and some Adobe software (Photoshop/Flash/Dreamweaver/Illustrator/InDesign/Fireworks) and that's all.

    The kernel is using excessive processor cycles. Below is a partial list of causes for this condition.
    Throttling
    When it gets high temperature readings from the hardware, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce heat dissipation. This condition can be due to an accumulation of dust, to high ambient temperature, or to the malfunction of a cooling fan or temperature sensor. Note that if the problem is caused by a faulty sensor that reads too high, there may be no actual overheating.
    The Apple Hardware Test, though not very reliable, is sometimes able to detect a bad fan or temperature sensor.
    Using Apple Hardware Test
    Encryption
    Transferring large amounts of data to or from an encrypted disk image or FileVault volume may put an extra load on the kernel. If both the source and the destination are encrypted, the load may be doubled. If you transfer data from an encrypted disk image on an encrypted partition to another such image on another encrypted partition, the load may be quadrupled.
    This issue probably doesn't affect late-model Macs with an Intel i-series, recent Xeon, or later processor. Those processors support hardware-accelerated encryption. You can determine what kind of processor you have by selecting About This Mac from the Apple menu in the menu bar.
    Installed software
    User-installed software that includes a device driver or other kernel code may thrash the kernel. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or booting in safe mode (with the shift key held down at the startup chime.) Note, however, that disabling a system modification without removing it or booting in safe mode may not be as easy as you think it is.
    Corrupt NVRAM or SMC data
    In some cases the condition has reportedly been cleared up by resetting the NVRAM or the SMC. I can't confirm.

  • 27" imac i7 16GB RAM mid-2010 turns off randomly

    I've done a lot of reading on the existing posts, and so far no real solutions except for removing RAM. I have 27" imac with APPLE-INSTALLED 16GB RAM. It is a mid-2010 imac model 11,3.
    The random shutdowns don't seem to correlate to particular apps or usage. They started a few weeks ago with shutdowns once in a week or so, and now are happening about 3 times a day.
    What I've tried so far:
    - installed istatpro temperature dashboard thing & smcFanControl. I've been monitoring HD and CPU temps and turning up the fans to keep CPU under 110 degrees F. Did not fix it.
    - reset SMC; did not fix it.
    - zapped PRAM; did not fix it.
    I see from other threads that others are having the same problem. The next thing I am going to try is removing RAM. I'll report back in the next few days what I discover.

    It's a new machine and still under warranty. Why are you bothering to play with it? Get straight onto Apple and take it back before you do something that voids your warranty.

  • Macbook Air 13'' Mid-2011 Keyboard and Trackpad freezing

    Hi,
    my trackpad and keyboard keep freezing. It only happens when I plug the power adapter in. Macbook keeps running, but only the on/off button works. After a hard reset it is fine.
    Here is an example of the console log when it happens:

    These computers have got a damaged NVIDIA graphic which may cause unexpected restarts, kernel panics, black screens... See > http://support.apple.com/kb/TS4088
    Fortunately, Apple is repairing these computers for free, so make a backup of your data and take your MacBook Pro to an Apple Store or reseller

    Well that's only a possibility, not likely. I'll stick with Mac as much as I can, which I imagine will mostly be ok. If I have to, I'll use their computers in class and do PC homework assignments from home on my more powerful iMac. The only thing I really thought about before buying it was its portability and the fact that I won't be using it for actual programming jobs after school. This is merely to get me through school.

  • MacBook Pro Turns off Randomly Only when logged in OSX 10.8.2

    Hi,
    I have a 2010 Macbook pro with Mountain Lion 10.8.2. For a couple of weeks now, when its not plugged in to AC it turns off randomly, not at any specific battery%.
    Things I have tried already that were not helpful:
    - System profiler battery: 374 cycles, Battery Status: Normal
    - SMC reset
    - Clean install of Mountain Lion without any Migraion of old System files (wanted to do this anyways before the problem arose)
    - Its does not seem to be a heating issue, has happened at low temperatures
    What I have noticed is that if I either run the diagnostics at startup or enter to recovery mode, I can run the battery all the way to 0% (lasts a while) and this random swtiching off doesn't occur. It only happens when I am logged in to OSX. This makes me think its not a battery issue either.
    Any help would be great.
    Thanks!

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    When you see the gray Apple logo, release the shift key.
    If you are prompted to log in, type your password, and then hold down the shift key again as you click  Log in.
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.  The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • My macbook turns off randomly but not completely because when I tap the touchpad it goes to the password screen and I am back to it in seconds. It's really annoying. HELP!!!

    My macbook turns off randomly but not completely because when I tap the touchpad it goes to the password screen and I am back to it in seconds. It's really annoying. HELP!!!

    1. Non volatile random access memory (NVRAM) is where the computer stores user's settings, like time and date, speaker volume, energy saver settings etc.
    2. Reseting NVRAM has no impact on anything on your hard drive, or anything else on the computer.
    See this note from Apple: http://support.apple.com/kb/ht1379

    You might be right about the reheating. Get iStat Pro https://www.apple.com/downloads/dashboard/status/istatpro.html
    To monitor your tems and fan speeds.

  • MBP Screen Turns Off Randomly - Battery Charge/Plugged In...

    Two to three times per day for the last several weeks, my 201 Macbook Pro screen will just turn off. If I am using Spotify, the audio will stutter and I'll be forced to hold down the power button and turn it off and on.
    Per instructions on this site, I ran the hardware test which said one RAM slot was faulty, bought a new stick, installed it, ran the test again, no more error messages but the problem persists.
    Otherwise the computer runs beautifully, no issues whatsoever. I'm running OSX 10.6.8 with 8 GB of RAM.
    When it comes back on I get the following panic report:

    Hello,
    I've got the same problem, it seems to came from faulty memory slots, not really from faulty memory sticks.
    In my case, I'm using a MacBook PRO 15" Intel I7 2,66 ghz from mid 2010 with two sticks of 4go DDR3.
    At first I had error messages like yours with reboots and so on ... After some weeks it gets worst : The MacBook wouldn't reboot, it plays 3 beeps with black screen instead of starting normally.
    I thought that it came from the memory sticks and replace the two sticks without any result.
    Lets call the two memory slot A and B (A the higher and B the lower).
    I tried to start the computer with memory stick in A : OK, some error messages and reboot by day, but starting ok.
    I tried to start the computer with memory stick in B : Impossible, 3 beeps and the computer wont start.
    I Have repeated this test with 4 different memory sticks, the result is always the same, B is no longer working ...
    I'm very disappointed, a computer like this that brakes in two years ... I'll go to my Apple Store next week, if you're intrested I'll give you the diagnostic ... and the price of the repair ...
