  • I was using my ipad 2 and i got up to use the bathroom and 2 minutes later it was shut off and wont turn back on. what is wrong?

    I was using my ipad 2 and got up to use the bathroom and 2 minutes later tried to use it and it was shut off and wont turn back on. What is wrong?

    We really can't tell you what happened, but you can get your iPad up again, by rebooting:
    Hold the power and home button simultaneously for at least 10 seconds (hold past the swipe to shut down) and when the Apple logo appears, let go of both buttons and your iPad will come back to life. 

  • I was charging my ipod touch and it was almost fully charged and shut off and wont turn back on. what can i do to turn it back on?

    can anybody help me? i was charging my ipod touch and it was almost fully charged and it randomly shut off and will not turn back on, anybody know how to fix it?

    Try the remaining items of:
    - iOS: Not responding or does not turn on
    - 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 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 iphone shut off and wont turn back on, what should i do

    i need help ASAP

    You may have to try to force it into restore mode. See this support document. http://support.apple.com/kb/HT1808. You may have to do this more than once. If this doesn't work, then you will need to make an appointment with the Genius Bar to have the hardware evaluated.

  • My iPhone 4 is shut off and wont turn back on, unless i plug it in an outlet & when i do that it says "connect to Itunes" & then i do that and the phone wont turn on & it shows nothing is plugged in . HELP!

    & it keeps trying to turn on but it wont . like the apple logo pops up for a minute , then turns off.

    Had exact same problem. Rang Apple support and various apple repairers. All of them said in effect, too bad, you'll have to lose everything since your last backup. It's a work phone with very important stuff on it and the latest backup was on a computer that had a virus. Convergence of crap :/
    Happened to talk to a friend who said to try replacing the battery. Did that. Problem fixed. All data saved.
    To all Apple support people: rather than say 'once it's in recovery mode you lose all data' try saying 'replace your battery and see if that works first'!!!!

    ronicr76,
    First it would be helpful if you post the exact model, year and OS version you have.
    > The LED light is on but only when the laptop is closed<
    So that light is the sleep indicator and tells us that the laptop is going to sleep when you close the lid. That would be normal behavior so the machine is still working. Possibly you're experiencing a backlight failure. With the machine supposedly "on" use a flashlight to carefully examine the screen. Do you see the desktop? Yes? machine is still running and something is wrong with the backlight.
    You should immediately backup your computer or at the very least pull vital files off. With the computer hooked to another Mac (The way this is done depends on the exact MacBook, E.g.FireWire 800 to FireWire 800.) Then you restart the computer and hold the "t" key down. This puts your MacBook into "target mode":
    How to use and troubleshoot FireWire target disk mode
    Once your files are off try an SMC reset:
    Intel-based Macs: Resetting the System Management Controller (SMC)
    Are you able to get the backlight back on by opening and closing the display? Yes? Broken backlight cable refer to qualified service place. Even if it doesn't come on and you can still see the desktop with a flashlight it is still probably the backlight. Could be the a backlight problem also.

  • My Iphone 4 shut off and wont turn back on, will a reset wipe my Data?

    My Iphone 4 shut off and wont turn back on. If I do a reset with the power and home buttons will I for sure lose all data that hasn't been backed up on my computer in the last week?

    No.
    A reset is very similar to rebooting your computer.

    Hi and Welcome to the Forums!
    Try leaving it on the charger yet doing nothing with it for at least 2 hours. Then try to power it on.
    Good luck and let us know!

    You can try putting it in bag with rice for about 4 or 5 days and the try to turn it on.  The rice will help the drying of the iPhone.  Do not attempt to turn it until you take it out of the rice.
    If it does not work after the rice, then you know you have to replace the iPhone.  This is very likely so after 30 seconds in a hot tub, but do give the rice a try.  If you can get a hold of some silica crystals, a better drying agent than rice, that would be good too.

  • IPhone randomly shuts off and wont turn back on again.

    Hi,
    I have a problem with my iPhone 4. It randomly shuts off and wont turn on again until i plug in the charger. This happens at least once a day and is extremly annoying and i can´t really use it anymore. I´ve tried a reset but with no results. Please help me out, thanks

    Hello again,
    I know there been a while, but I just need to tell you this
    I tried a restore and it didn´t work out. The same problem just continued and i started using and old phone instead. A couple of days ago I read something about ios6, and I thought: Why not try it on my iPhone that I don´t use? I installed ios6 and since then the phone have worked perfectly, except for one single hangup but then it was just to restart it. Ios6 beta 2 is actully really stable. I mean, now at least it´s a fully functional phone.

  • Galaxy S4 Shut off and wont turn back on.

    Hey. I don't have insurance on my phone and I've had it for over a year so I cant get a new one. But, today I was using my phone it was around 70% battery and it shut off. I was using the calculator app when this happened. The phone now wont turn back on, connect to a charger, and is not recognized by a computer. What happened?

    Try (while it's still connected) holding the MENU and SELECT (center) buttons until you see the Apple logo to reset it.
    Cheers!
