Please help, computer turns off on its own!

New generation aluminum iMac turns off when it wants. It has happened 3 times now when I am using the computer it will just shut off.
I do not turn the computer off, as I never have with macs, but always put it to sleep when I am not using it.
After it turns off, I am able to turn it right back on using the power button and all seems to be normal.
Any ideas for me!? Please!

I'm glad someone else is having this problem. Mine has shut down 3 times as well. Each time I'm doing something different - so I doubt it's related to programs that are running, etc . . .
Today I called AppleCare - they had me reset the SMC and PRAM as well as a couple other software things.
It hasn't happened again - yet - but it has only happened about once every 2-3 days.
I'll keep following for other good ideas!

Please help - computer turns off randomly

I purchased my computer in the US in september - right before I moved to London. Mid november it died. The computer would turn on and chime, but the screen was dead. I took it to a 3rd party repair (which apple phone tech support insisted was just as good as the apple store) and they replaced the logic board. It all seemed fine until I took it home and used ichat video with my family - the computer turned off. It didn't shut down, just seemed to pause and go dead. I could reboot it and it had no recollection of incorrect shutdown with the exception of firefox. (I dont know if this is important, but every time it does this and i reboot, the sound resets to mute) I started to notice that the computer does this any time I use video functions for an extended period of time (or at least 20 minutes). I have brought it to the apple store twice, where they have repaired it twice. I have gone through at least one more logic board, a heat sink, something to do with the power adapter, as well as the battery. They cannot find anything wrong - 3 repairs later its still shutting down so I went to apple again. Unwilling to give up my computer YET again, they recommended I archive and install. I have now done that - now my computer is crawling - still crashing - and some programs decide to open up occasionally or start and stop without a crash notice. I tried to run disk utility and it froze. On top of this all, they recommended I download xslimmer to convert old power pc programs to the current intel format I'm running on my new macbook - this seems to have complicated things more. I asked them to replace the computer during my last genius bar visit, i was told that because my computer was purchased in the states they cannot replace it, and I will not be heading back to the states soon enough to have it replaced there. So anyone with any insight, please help! I bought a new computer so i wouldn't have to deal with these problems and its turning out to be more of a headache than my old powerbook g4.

I also forgot to mention that every 45-60 seconds there are two faint tick sounds coming from inside the computer.

Hey NelanieA. Antoni,
Thanks for using Apple Support Communities.
So your iPad turns off on its own. Take a look at this article. Even though it says iPhone the same troubleshooting steps apply.

Try this.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up

Can a one please help me turn off auto play for Facebook the option is no longer in my General settings why is this ?

Can a one please help me turn off auto play for Facebook the option is no longer in my General settings why is this ?

And yet the link you posted only tells you how to do it on the Facebook App for Android. Nothing about the Facebook page is mentioned at all, or how to do it on an iPhone.
With that said, and assuming you have the most up to date version of the Facebook App, you can now turn the auto play feature Off within the Facebook App itself. Tap on the "More" icon on the bottom right, then scroll down to Settings->Videos and Photos->Auto Play. If Smart auto-Play is on turn it off. Then you can set the check mark on "Never Play Videos Automatically" which is the same as Off.

Try a restore. If that does not work, you probably have a hardware issue.

MacBook Pro turned off on its own and now won't turn back on.

MacBook Pro turned off on its own and now won't turn back on. Battery had 41% just before this happened and green indicator on power cord is showing, so it seems like it's charging. What should I do?

The led on the power adapter should be amber if it is charging. Green just indicates that it is supplying power to the MBP.
Try a SMC reset:

6th Gen Nano turns off on its own

My nano is turning off on its own after a few minutes of play. Any advice?

Your nano is pausing playback when the screen goes dark (Either when it goes dark on its own or when you click the sleep/wake button). The reason for this is that it is not detecting your headset. You may be able to hear music, but the headset jack is not inserted enough for the nano to detect that it is there (or something is blocking the connection). Here are your three options:
Insert the headset jack harder. Most folks find that this solves their problem. If you can see ANY of the silver of the plug when it is inserted, it is NOT fully inserted. You should feel and hear a click" when it is fully inserted.
Clean out the crud in the headset port. If you have tried #1 and it just won't insert all the way, it is likely that you have crud in your headset jack. Shine a light in there. The entire inside of the jack is white, so if it looks dark down at the bottom, there is probably crud down there. You can try blowing it out or using canned air. Just understand that shoving anything else in there to clean it out will be taking your warranty into your own hands! However, I have cleaned mine out using whatever was handy and small enough to fit in there and so far so good. Your results may vary!
Take it to the Apple store. If you have really tried with 1 and 2 and it is still happening, then there might just be something up with your headset port or your headset jack. If it is the headset jack, you can look closely at that and be pretty sure if that is the problem. Try another headset to make sure. If you have worked all the way through to this point and it is still happening, it is time to take it to the Apple store.

IMessage turns off on its own, can't be turned back on

I have an iphone 5, and starting this morning none of my texts or imessages would send, and I can't receive messages either. If i turn my phone off and back on, messages will send and receive like normal for about the first minute that it's on. After that if i go into settings -> messages, it appears that imessage has turned off on its own, and can't be turned back on. Basically I've had to restart my phone every time I want to send a message, and when I do restart it, messages finally pop up that had been sent to me hours ago. I have tried resetting my network settings, toggling the imessage on and off (it won't let me do that though), a hard reset, and restoring to factory settings. Nothing has worked and I'm not sure what else to try.

RESET DEVICE
Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for device to restart (no data will be lost).

Macbook turning off on its own

About a month ago, my macbook started turning off on its own. Then when i turned it back on it loaded and then turned off several more times before i turned on a stayed on. Then it didn't happen anymore, so i thought it was a fluke. Now it has started doing it again. The battery says it has a lot of power left so its not that. Has this happened to anyone else before? What should I do?

Also, in the meantime, when you turn it back on after a shutdown, hold the on button down until it chimes you hear a loud sound. Apparently, that limits the macbook to using one of its processors, and for me and some other people, it stops or reduces the shutdowns so you can use the notebook until you get it repaired. I had a new heat sink put in in October, and mine hasn't shut down by itself since then.

Why does my phone constantly turn off on its own as if the battery is dead?

why does my phone constantly turn off on its own as if the battery is dead? Its so annoying! Every day once my battery life span is at about 40%, my phone will start shutting down with the dead battery sign once it is down. Then after about 3 minutes i can turn it back on.

Tons of people have this problem with iPhone 4S and 5, whether they are on iOS 6 or 7. You can only hope that one day Apple realizes that this bug (software ? hardware ?) is a *real* pain. So far, they haven't paid attention.

My iPhone 5 keeps turning off on its own randomly what should I do

My iPhone 5 keeps turning off on its own randomly, sometimes turning itself back on automatically but sometimes staying off, i have tried a system restore but has no effect, what should I do?

Do you have a case on the iPhone? Did you accidentally drop it or damage it in anyway?
You could try restoring the iPhone and setting it up as a new device, as shown here -> iOS: How to back up your data and set up as a new device
