Macbook Reboots on its own...

Hey All-
So something weird is happening to my mac. Seems to randomly reboot each day, sometimes multiple times a day. I can't figure out why.
I use it all day, come back and it has completely rebooted and waiting for me to log in.
The Mac is less than a month old and I have nothing special installed or changed anything physical.
Not that this is a big deal, just worrisome since I have no clue as to what could be causing this.
Thanks for any ideas what to check etc...

Hi tmerritt42 and welcome to Apple Discussions.
You are right to be concerned as this is not normal behavior. Don't give up yet, though, there are lots of things we can do to get this fixed up.
Any time there is an issue that may involve power to the computer, I recommend resetting the System Management Controller as described in [this Apple knowledge base article|http://support.apple.com/kb/HT1411]. Try the procedure and let us know if anything changes.
Best of luck.

  • MacBook doesn't reboot on its own, but will from Startup Manager

    I have an early 2009 13" MacBook Pro running Snow Leopard. About a week ago I attempted to use Boot Camp to install a Windows partition, and for reasons that don't matter to my current problem, I gave up on that and used the Book Camp Assistant to remove the Windows partition and return to a single Mac OS partition.
    Since then, if I reboot the machine and just let it reboot on its own, it will stop at a black screen that says "No bootable device -- insert boot disk and press any key". I have to power off the machine to reboot from this point.
    However, if I reboot the machine and hold the Option key to get the Startup Manager, my hard drive will be shown which I can then select and it will boot Mac OS like normal. After that it will run like a champ.
    Any idea how to fix this short of a fresh install?
    Thanks in advance for any assistance!

    Glad to help.

  • Why does my mac reboot on its own?

    Why does my mac reboot on its own?

    Oh den.thed...  I saw your post this morning and I was so excited....  ran to the Mac and got to Energy Saver, and...  the checkbox is already unchecked. 
    Long story, I'll make it short.  Just got the Mac back after having the HDD replaced.  (It stopped working after less than 500 hours.)  This rebooting thing has been happening ever since I got the computer in 2010, and I was hoping it would coincidentally stop happening after having this crashed HDD replaced last week.  No such luck.  Still doing it, even after getting the computer back from Apple.  Two of my kids have macbooks, have used the cr*p out of them, and have had very few problems (nothing big).  I bought this Mac, to replace a dead Dell desktop that got very little use, and so far I am not sure I did the right thing.  Really wish I could get this "automatic" rebooting thing fixed.  (Reboots with no notice, while doing normal tasks - internet, word docs, etc.)  Thanks again for your help.  Let me know if I should try anything else.

    Your graphic card is damaged. This could be related to extensions, but the kernel panic gives you the message that your graphic card has failed.
    You can only make a backup of your files with Time Machine or Disk Utility's Restore feature, and take the iMac to an Apple Store or reseller. Your computer has got the graphic card soldered into the logic board, so this will be a very expensive repair

  • I have this problem were my iphone just reboots on its own

    I have recently upgraded to io6 and my iphone 4 cdma started rebooting on its own. I took it to a store and they said to take the battery out because it was overheating. So now i lay with a iphone without a battery. Is there any way were i can take it to the apple store so they can fix it?

    Check your mouse configuration, if you have a Mighty Mouse, one configuration is to have the side buttons launch Dashboard (widgets) or click the scroll wheel for example.

  • Since installing Firefox 29, my router constantly reboots on its own

  • P55-GD85 shuts down then reboots on its own?

    I have just set up a new P55-GD85, when I shut it down, it reboots on its own?
    I would appreciate ideas on how to fix this do do a normal shutdown

    Did you try disabling every option in the "Wake Up Event Setup"? 
    I just checked the Changelog for the latest BETA Releases for your board.  The latest BETA Version is A7585IMS.132 [v1.3b2] and among other things it includes the following fixes that seem to address the problem you are experiencing:
    Quote
    - Fixed WOL still work after disable LAN controller.
    - Fix after use LAN (on PCIE slot) wakup S1,system can't shut down from OS issue.
    For you, this means good news:  Your problem is already known and was, at it looks, already fixed.  All you have to do right now is to contact MSI Technical Support and ask them to provide you with that BIOS Release.
    http://support.msi.com/
    Once you have the BIOS, ensure that your system is stable and then use the >>Use the MSI HQ Forum USB flasher<< to flash it (please avoid M-Flash or Windows based method for minimum risk).

  • Ultra not booting, reboots on its own, display - possible solution for all.

    I had a problem for a few days where my Ultra 24 would stop (the screen would freeze for a sec), the fan would make a lot of noise and the PC would reboot on its owns. Sometimes it would be on a loop or not start up at all.
    I perused through these boards and saw other people with similar issues and solutions. (Mine was to take out MB battery and reset bios).
    This fixed the problem but it eventually came back at least once a week.
    Anyways after calling Sun and spending a lot of time on the phone I determined that this is related to the graphic card. You'll notice that the nvidia driver these workstations come with are really outdated drivers (mine was the quadro nvs 290).
    After I updated the driver (05/08) the problem has gone away and graphics perform MUCH better.
    I am running running Solaris 10 and XP.
    Hope this helps some of you out.

    We have a T-Mobile corporate account with several of these 8120's.  We have had them since mid-July and now 3 out of 10 of them are having the reboot issue as well.  We, however, do not have or use any memory cards in them, so I don't think that is the problem either.  We've reinstalled the software (they had the same version as the newest already installed) as tech support has suggested, and still the problem happens.  It happens sometimes when the phone is idle, but most of the time they reboot during a conversation.  This is quite annoying as they are business phones and it takes 3-5 minutes for the phone to complete the reboot process.  Any help on this would be greatly appreciated.

  • My ipad freezes, reboots on its own and when I try to restore the machine reboots before the process ends

    Just bought this ipad in June 2013 and then all of a sudden about two weeks ago, I discovered the machine reboots on its own and would only be active for less than 2 minutes.  I check the auto-lock assigned minutes and it was set on 15 minutes even at this, it will still go off after less than 2 minutes.  I then checked on some of the suggestions on the net for a similar problem and resolved to pressing and holding the sleep/wake button simultaneously with the Home button to force a reboot.  Even at this no change.  Then I tried connecting the machine to a PC logging on to the itunes to do a backup and restore but the machine will not stay long enough to complete the procedure before rebooting on its own.  Any help?

  • HP 2140 Mini reboots on its own...

    Hello everybody, I need your help.
    My HP2140 Mini reboots on its own after being shut down. This only happens when it's on AC-Power, not when on battery power only. It's due to a software glitch and not due to a faulty power supply.
    I had this problem once before and was able to get ahold of a software fix that stopped it from doing it. That software fix came directly from HP and was emailed to all HP2140 Mini owners.
    Since I had to reinstall the Operating System again, that software fix is now gone and I don't have the email anymore.
    Can anyone help?

  • Imac reboots on its own

    I have a 20 inch Imac Intel. I have had the logic board and airport card replaced. Every day before and after the repairs my computer will reboot on its own. Steps I have taken so far:
    1. PRAM resets
    2. Testing Via TechTool (Came back fine)
    3. Deleted Powermanagment in System Preference.
    I have memory from Other Computer World installed. When I ran the tests from TechTool it said the memory was fine. I was wondering if anyone else's IMAC does this. If it does how did they fix it

  • IPhone reboots on its own -

    Wondering if I can get the attention of some of the mods -
    My iPhone, when docked and playing music, reboots on its own. I touch nothing, it is not connected to anything but my desktop speaker system and it is working itself through the playlists.
    Odd behavior that I have not seen when it isn't docked.
    Thoughts are welcome.

    Try a powerdown. If that doesn't work. Try a reset. If that doesn't work, try a restore. One of those should take care of it.

  • Phone reboots on its own

    My 8520 turns off and reboots on its own several times a day.  
    Any solutions?
    Thank you

    I haven't particularly noticed that exact point when the problem occurs - on two occasions it happened when I was replying to a message, once it happened when I was listening to music and another time after a long con call. So to answer your question - am not really sure...the reboot occurs unexpectedly. I read on another blog that this is in inherent phone problem and for this person, the seller replaced the phone. Another blog suggested that I format the memory card and hard reset the handset...please suggest...and thank you
