Apple pro 27" turns off by itself and then u have to wait 15 to 20 mins and have to unplug and reboot

applepro turns off by itself and then i have to wait anywhere from 15 to 30 mins to try to reboot and have to unplug

You should really be asking this question in MacBook Pro: Notebooks: Apple Support Communities
because this sounds like a overheating problem and we're the Mac Pro (desktop workstation) forum.

    Try a SMC reset.

    It might be helpful if you indicated the exact model/year of your MBP.  Are you running Lion OSX?

  • IPad turns off by itself and returns to apple logo screen

    My iPad turns off by itself and I need to wait for 2-3 minutes for it to open and then it will turn off again and wait. I already tried pressing home and off buttons for 10 seconds but nothing happens.

    Try restoring the iPad software.

    If that does not work, you may want to try recovery mode.

  • Airport turns off by itself and won't turn on back again!!!

    hey there, i am currently facing an issue with the airport as by it is turnning off by itself and i cant turn it back on .. i have to restart !!!
    sometimes when i turn on my mac like just now happened it is off and can;t be turned on.
    please if anyone can help i would really appreciate it
    thank you very much

    Hey, in case you haven't been able to find a solution to your original problem with airport turning off, i seem to have found the solution for my MacBook Pro. I called Apple Care and they had me to shut down my computer. Then, while holding down the four keys: command, option, R and P, push the power button to turn on the computer. Do not let up on the four keys until the start up chime has sounded twice. Then let up on the four keys and the OS will boot up as usual. They said what that does is reset your "sleep" parameters on your computer. This seemed to have solved my problem.

  • I am having trouble with my i pad it freezes it turns off by itself and the screen turns blue?

    I am having trouble with my i pad it freezes and it turns off by itselfI and screen turns blue?

    Start by rebooting the iPad by holding both the power and home buttons until the apple logo appears and it restart, ignoring the red slider if that appears.  See if that helps.

    Hey guys

    A device that has been jailbroken cannot be discussed on these Communities...Apple will not help you as that voids your warranty.

  • My iphone turned off by itself and it doesn't turn on

    My iphone turned off by itself and it doesn't turn on, What should i do????

    IIf the battery was completely drained it might take some time before the phone will respond. Wait at least 30 minutes with the phone connected to the charger. Then reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. If the phone starts up let it continue to charge until it's 100%.
    if the broken button will not let you do the reset Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

  • I have a new MacBook Air which keeps turning off by itself and now won't turn on at all...

    It's been working fine since I've had it but yesterday it kept turning off by itself and then within minutes off turning it back on it would do it again. Also the little box kept popping up asking if I wanted to sleep, restart etc as if I had pressed the power button. I tried to turn it off completely and now it won't turn back on at all. If I plug the charger in the green light comes on but nothing happens on the actual MacBook itself. What do i do ?

    Usually the HDD is the frist place to look.  Use the original install disk and start up the MBP with the C key down.  Go through the installation process until you see on the display a menu bar on top.
    Click on UTILITIES.
    From the drop down menu select Disk Utility.
    Open Disk Utility>First Aid and run Verify and Repair.
    What are the results?

  • Why does my ipod turn off by itself and then turn back on after up grading to ios 7

    why does my ipod turn off by itself and then back on after upgrading to ios 7

    Try the standard fixes:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup. See:                                 
    iOS: How to back up                                                                
    - Restore to factory settings/new iOS device.             
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • My razr m just stopped working turned off by itself and will not turn on

    my razr m just stopped working turned off by itself and will not turn on

    raamw,
    My wife has the exact same phone and I have the razr HD (basically the same, just larger screen etc).
    We have run into the same thing a few times, and as stated above by Callie I have found it is a dead battery issue. BUT unlike my previous phone (Droid incredible) that I could usually plug in, wait a few minutes, then at least turn on and use while plugged in, I have found for the M and mine it really took a bit to get it charged.  Kind of like as long as there is some battery you are ok, but once it dies it takes a bit of charging.
    ALSO - I am going to perhaps not use the right terms or words for this, but  I THINK (emphasize think) at least once it wasn't enough to use one of the lower amp chargers.  at least on mine.  tried to charge and charge and didn't seem to work.  Finally I took a charger that I normally need to use for my daughters tablet and use that then it had enough kick.  I will note I think that was the issue.
    regardless each time yes it took awhile before we could turn them on.  ALSO it seemed like it took a much longer time in holding the power button down.  BUT eventually they started up and we were good to go.
    we love our phones, she especially loves the size of the M.  BUT we have learned in the short 2-3 months we have had them, if possible, don't let the thing drain all the way.  just seems to cause a bit of a hastle
