Q: iPad restarting on its own

Hi,

I have iPad 4 running on iOS 7.1. It has been working fine since last two years. But, suddenly it has developed issues since yesterday. It has been restarting every two minutes. I searched through the Apple Community and carried out steps like restoring factory settings and turning off notifications, but these didn't help. I then looked at the diagnostic log and could find out that it has bug_type 110. I could understand from various other posts that this could be a hardware issue. Any other suggestion from anyone before I approach the Apple Store. Below is the dump which could could provide more information. Any help is much appreciated.

    Hello, debjyoti.  

     

    Thank you for visiting Apple Support Communities.

     

    I see you have tried some troubleshooting steps already with there issue persisting.  Here are some additional troubleshooting steps to go through when experiencing this issue.  They are labeled for the iPhone, but apply to the iPad as well.

     

    Will not turn on, will not turn on unless connected to power, or unexpected power off

    1. 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.
    2. Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
    3. Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    4. 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.
    5. 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.
    6. 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.
    7. If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

     

    If the issue persists, see the section labeled Issue not resolved.
