What causes my i4s phone to randomly shutdown?

What causes my 4s phone to randomly shutdown?

Do you have a case on the iPhone? Maybe it's pressing on the home and sleep buttons, making it reset itself.
If that doesn't work, try restoring the iPhone then seting up service.

  • What causes the Apple Notes to randomly be deleted from the note app?

    My wife and I both have iPhone 5s. She is running 6.0.1 and I am running 6.1.3. We have both had notes just be deleted from our pre-installled  notes app. Neither one of us have deleted these notes manually. I am synced to my iPad but she is not synced with any other device through the cloud. Can anyone help please?  Thank you.

    Obviously it's better to happen now, and I WILL exchange it. I'm just wondering what the cause it, since this is the 3rd time this has happened to me.
    If you don't have an answer, that's okay too. Even the Apple "Geniuses" didn't know.

  • Random shutdowns: my experience, and a suggestion

    I own a BlackBook whose random shutdowns began a couple of weeks ago.
    During my first trip to my local Genius Bar, the guy behind the counter reset the PMU and PRAM, and was unable to reproduce the problem, and sent me on my way.
    The random shutdowns continued.
    During my second trip to the Genius Bar, the guy was able to boot the machine from another drive, and was able to reproduce the problem. The machine was sent to the repair center for servicing. I got it back a few days later.
    Random shutdowns have still occurred, but I find that if I reset the PRAM as the machine is booting, and wait for at least three startup chimes before letting go of the key combination (control-option-P-R), the machine seems to stabilize and not shut down on its own, at least so far.
    Before repair, the machine was also exhibiting the "vertical colored lines at startup" problem. Before that, it needed a replacement power adapter and a replacement battery (the battery was refusing to take a charge or even be recognized by the computer).
    Various theories for the cause or causes of the problem with random shutdowns have been suggested -- along with a number of magic-bullet solutions from different sources. My guess is that even Apple isn't sure what's causing the issue, and there's certainly no foolproof solution that the user can apply. We'll just have to wait and see what comes of the investigations.
    Despite these problems, I still love the BlackBook and think it's perhaps the most beautifully designed computer ever made. I assume that once these growing pains subside, Apple will have a total winner on its hands.
    MacBook (black) 13"   Mac OS X (10.4.7)  

    I have a whitebook bought in June, shutdowns started about 6 weeks after I got it. Did the whole tech support line thing several times resetting various things etc. No change. Sent it in for repair with a strong encouragement that it would only take 48 hours. It is now 10 days later and repair is still on hold. Sent in several "why is this dragging on" and got nice automatic reponse saying they would respond in a day or two. No real responses yet. Called today the helpful tech said they would check and see what was holding things up and let me know when I called back in 48 hours. Assured me I would not be without my Macbook more than a week longer. Have missed work and have a presentation on Friday that I will have to do without it. Had I known it would take this long I would have taken my chance that it would not shut down mid stream in the presentation. I am very disapointed with Apple at this point. Have been a long time user and own stock etc. This is the worse customer service I have gotten on a computer problem, personal or business. Apple needs to realize they have a batch of lemons on their hands and bite the bullet and replace them. I am not encouraged to hear others are getting their books back repaired only to find the problem on going.

  • Whats next if all else fails with random shutdowns

    Hi, having random shutdown on battery power on my 'macbook intel 1.83 core duo' no warning of low battery etc always ample battery power available.
    Have installed battery update 1.2 twice
    Have reset the SMC twice to no avail
    Next stop apple repair centre, but what's the most likely outcome has anyone had this issue resolved by repair, and if so, what was the cause.

    I am in the same situation, save that I have not yet tried re-setting the SMC. My MacBook is still under guarantee, but the local Apple shop can suggest nothing more creative than that l leave the notebook with them for a week plus. That is impossible for me -- any more than half a day, and I need to have a stand-by replacement into which I can slot my hard drive, but that is most certainly not on offer. It is the more irritating in that it is now apparent to me that Random Shutdown Syndrome been the subject of complaints literally for years, and comes as no surprise to Apple. I am beginning to wonder whether the AppleCare Protection-Plan was worth what I paid for it.

  • Random Shutdown and Previous shutdown cause: -x2

    Hi,
    I had twice "random shutdown" for now. My MacBook is about 4 month old and It happend with about 3 weeks between them.
    I tried stress testing it with 'yes >/dev/null' heating it up and cooling it down several times but I could not reproduce the Problem. However, looking at older system.log files, I found the "Previous shutdown cause: -82" lines in there. My question: Some MBs seem to report -72, others -82 as the shutdown cause known as random shutdown but what actually is the difference? Is it possible to guess the time it will take to get it repaired depending on the shutdown cause (which obviously describe two different conditions)?
    Thanks a lot in advance and sorry for my somewhat clumsy english;-)
    Peter

    I don't know where you are in Austria, but I took my RSD macbook to mcshark in Vienna, and they repaired it, replaced the case, and returned it to me in one day. That was last Friday and it's been working great since. They knew all about the heat sink problem, didn't even ask for my user name or password, left my hard drive completely intact - they were absolutely super.
    If you are anywhere near Vienna, call McShark and make an appointment - they'll repair it quickly for sure.

  • HT201335 What causes the TV screen to freeze but sound continue on TV when using Air Play from I Phone?

    What causes TV screen to freeze but sound continue on TV when using Air Play from I Phone 4?

    First try rebooting ATV and router. Beyond that, it's probably something within the network, typically interference.
    To get a report of the network go to istumbler (Mac) or netstumbler (PC). Look for signal strength and noise.
    If on wifi try ethernet.

  • My iPhone 5 randomly shutdown and rebooting doesn't seem to work for me, what should I do?

    It also happens when I'm charging my phone, and also the battery percentage doesn't show that correct battery level not unless I turn off and on.. I tried rebooting the phone but it doesn't seem to work for me, random shutdown still happens..

    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 30 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

  • Mac randomly crashes, screen turns green and white, and it works fine upon restart. What causes this and how can I fix it?

    My MacBook Pro 13 inch (I've had it for about a year and a half) has started crashing randomly. It happens about once a week and it will happen when I'm in the middle of either watching a video, typing a paper, playing a game, etc. The computer clicks loudly and the screen becomes a series of green and white lines. It works fine upon restart, but it's still annoying whenever it happens. What causes this? Is it fixable?

    The image suggests an issue with the graphics board.
    The issue may happen more when your machine is generating additional heat, as when you're watching or processing video, or gaming. I can't say for certain, of course, but certain things will reduce the chance of the problem recurring:
    1. Keep your machine as cool as possible. When there's additional heat, turn up the fan, or use an app like HD Fan Control to reduce the heat. Use your computer the way you see fit, but be conscious of heat.
    2. Back up on a regular basis. Logic board problems can lead to more serious issues down the line, so backing up is a good way of safeguarding your data.
    3. Look up "Logic Board Woes" on Google for a comprehensive discussion of the issue.

  • MacBook 3x went to service center, still random shutdown, what to do next?

    Hi! Mine is week 17, and mainboard already replaced for 3 times. The last one they replaced the battery also.
    There is no Apple Center in here, I deliver it to the local authorized Apple service.
    I just got my 3rd replacement yesterday, and I noticed from the first place that it got blank gray screen on startup & can't sleep using the Energy Saver. But I waited long enough for the repairement, so I decided to take it home anyway. At home, I did the commandopt+pr and reinstall it back to 10.4.6 using the equiped cd. But still it can't sleep using Energy Saver..
    But the blank gray screen problem is gone.
    Today I calibrate (since they replaced the battery with brand new one), after the process done (5 hours sleep, zero battery), I plugged the magsafe and I heard looping click sound, and it went random shutdown again!
    And it goes shutdown on: yes dev null
    I just do the commandopt+pr, and the yes dev null havn't invoked the shutdown. But from my previous shutdown experiences, it will go crazy random shutdown in about 3 days ahead from now.
    So what to do next? going to the authorized service again?
    I'm sick and tired now.
    Also the outer body case is suffers little scratches, and it's getting mucher and mucher everytime I got it back from repairement.
    Oh dear God do help me! All I want is for my money back, at least a new replacement for my MacBook.
    And they said Apple wouldn't allow it.

    Since you're not actually turning it in to Apple for repair, I wonder if the repair shop that's doing the work knows what they're doing. Since you've had the logic board replaced three times, that's pobably not the solution. I had the random shutdowns and verticle lines on the display, and Apple replaced my heatsink and then erased the HD and re-installed to factory settings, 10.4.6. I then migrated my data from my backup HD, updated OS to 10.4.7, and installed the SMC firmware update. No problems since then.
    Many other users have had their logic board replaced more than once only to continue having the problems. Some have had logic board replaced once and then no longer have problems. Others have had other parts replaced, such as in my case and have had no problems.
    Apparently each MacBook has to be diagnosed individually to find the problem.

    You need to continue with the Recovery...
    Once the Device is in Recovery Mode... it is too late to save anything...
    To minimise loss... After the successful Recovery... Restore from the most recent Backup...
    Restore from Backup

    You downloaded a profile from somewhere. If it's not one you want or need, delete it.

  • Random shutdowns: what should I do?

    I'm getting really annoyed by the random shutdowns. what should i do?
    i live in the UK, and my local apple store is about 2 hours away.

    Just call Apple support up and tell them what is going on. In my case, I just started telling them of the random shutdowns and that I had tried everything that they were fixing to ask me to do. No further questions were asked and the sent me a return/repair box the next day. Now I'm just waiting to get it back and hopefully it will be fixed.
