- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable              
- Try on another computer                                                       
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • My screen just shut down and it wont turn on

    My screen just shut down & wont turn back on What can i do?

    What happens if you try a hard reset?  To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.  You may need to attempt this more than once. 
    Otherwise, connect it to an external power source and leave it to charge for a little while and then try a reset again if necessary.

  • My Ipad2 just shuts down and will not turn on. Rebooting does not help. He switched on when I start charging it. In this case, the battery is charged.

    My Ipad2 just shuts down and will not turn on. Rebooting does not help. He switched on when I start charging it. In this case, the battery is charged.

    Standard troubleshooting steps in the following order:
    1. Reset: Press the sleep/wake button & home button at the same time, keep pressing until you see the apple logo, then release. Ignore the slide to power off.
    If no change, continue:
    2. Restore your phone from a backup, note: if the problem is related to corrupt data, while this will restore a fresh OS, it will also restore the problem.
    If no change, continue:
    3. Restore as a "new" phone in itunes & re-sync your content. All saved data will be lost.
    If no change, make an appointment at an Apple store.

  • HT1222 I started the lastest iPhone 5s software update then my phone just shut down and will not turn back on. I've tried the home button, the button plus the top right button together for 20 sec, plug it in and nothing

    Plug your device into the original charger & block in a wall outlet and leave it alone for a couple of hours. Then, while it is still plugged in, restart it by holding down the home button and the power button for 10-15 seconds until you see the Apple, then let go.

  • My iphone just shut off and now wont turn back on.. is stuck on the apple screen.

    my iphone 3gs is locked up...  just shut off in the middle of a text...  tries to turn it back on and it wont go past the aple screen??

    Try resetting your iPhone by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
    If you can't do that, try Recovery Mode... http://support.apple.com/kb/HT1808

    my iphone just shut down and wont come back on what could be the problem

    Connect iPhone to Wall Charger for 10 minutes, it my turn ON itself. If still OFF, then keep on charger and Reset, hold both home and power buttons until the iPhone begins to start, this can take about 20 seconds time holding both buttons while on charger.

    Hi aaliyafrommarkham,
    In order to troubleshoot this, I would recommend that you start with an SMC reset. Information on this procedure can be found here:

  • My Mac just shuts down

    Looking for any answer on why my Mac just shuts down at times. It doesn't matter if I have a full battery or have it plugged in, there are random times when my computer just shuts completely down and I can't figure out why that is. Has anyone else experience this? Any thoughts on why it is happening?

    do a software update, if that doesnt work, try opening disk utility in user\applications\utilities. then repair disk permissions. if that still doesnt work, then reset the pmu and pram. reset the pmu by shutting down, disconnecting the battery and powercord, and holding down the power button for 5 secs. i know this sounds ridiculous but it actually does something. next reset the pram by connecting a both power sources and holding the option-apple-r-and p keys. press the power button while holding down those keys and hold the keys until you see the grey apple and the spinning gear. (if you want to, just press the first three, press the power button, and then immediately press the p key. if this Still doesn't work...then your in an even bigger pickle than you are right now...which isnt much of a pickle...nothing should get erased from your hard drive just to let you know...

  • Can't get MAC to shut down and start up via the schedule button in system preferences energy saver. Is there another way?

    Can't get MAC to shut down and start up via the schedule button in system preferences energy saver. Is there another way?

    Try this to start:
    Repair the Hard Drive and Permissions
    Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

  • Ipad will just shut down and not power back on until it is plugged in

    Ipad will just shut down and will not reboot until it is plugged in. Any suggestions??

    I'm going to guess that your battery isnt just dead?
    Have you tried a reset? Hold down the sleep and home keys, past when you see the red power down slider  and until you see the silver apple. Let it reboot and see if that helps.
    If it won't hold a charge, make an appointment at your local apple store and have them take a look at it.

  • My iphone just shut down and i cannot get it started again

    my iphone just shut down and i cannot get it started again

    Hey Barry,
    It really depends on the circumstances.  If you haven't powered your phone off yourself for quite some time, sometimes kinks can just happen and this sounds like one of them.  Every so often on mine I will have to use this method but it is in the very minority of occasions.

  • When I try to calibrate my iPod nano after a run it just shuts down and restarts. Whats happening?

    After I run (iin basic mode) I try to calibrate. (I've done this a few times before).
    Lately when I do/try this the iPod just shut down and restarts.
    I've tried restoring the iPod in iTunes to no help.
    It's a 6th generation nano coupled to a nike sensor.
    Any help would be much apreciated.

    As a test to determine if it is nike sensor only issue run once without the sensor. Use the inbuilt accelerometer to complete a run and calibrate it.
