How to Restart Nokia Lumia when it hangs

I came across with a strange situation with one of my friends Nokia Lumia 720. It runs on Windows Phone 8 and I’m also an owner of same phone. I was curios to know the problem and its solution. Let’s first have look for the problem:

  • Nokia Lumia 720 not switching off / Windows Phone 8 not switching off.
  • Nokia Lumia 720 screen black out / Windows Phone 8 screen black out.
  • Nokia Lumia 720 power button not working / Windows Phone 8 power button not working.
  • Nokia Lumia 720 nothing shown on phone when someone calls to it / Windows Phone 8 nothing shown on phone when someone calls to it.
  • Nokia Lumia 720 can’t power it off using PC also / Windows Phone 8 can’t power it off using PC also.

Nokia Lumia 720

As we all know that battery of phone is not replaceable as it is fully covered. So one can’t restart it by taking its battery out and all other options are not working. Here is the perfect solution for it:

Hold down and press the Volume down button and Power Off button for 15-20 seconds. Both buttons must be hold down and pressed simultaneously. Your phone will restart within few seconds. If it doesn’t work that please repeat same for 30 seconds it’ll definitely work.

Hope this solution for Nokia Lumia not restarting or Windows Phone 8 not restarting, will be helpful for all. Stay Connected and tuned.

      I experienced the same ,,I cant switched on my fone ..but this doesn’t work for me,,is there any more actions I could do to restart it?

  • Christian

    Thanks, but why it happens? I think it’s the WhatsApp app, because sometimes it’s after check or send or something with Waths.

    • http://www.unlockwindows.com arvindk

      There are some apps like Whatsapp which are not developer upto the mark for Windows Phone. Whatsapp crashes so many times and because of which Phone shows some glitches over display. So it may be the one of the reason.

    My problem is little different . My phone is working normally but its power button is not working . After using the phone wen I try to lock the screen its not locking . After one minute it will automatically lock and if I wana use it again I cant unlock it until someone messages me or call me .

    • http://www.unlockwindows.com arvindk

      This problem is coming in Lumia 620 also. It’s because of the Power Button only. Hardware part of the button is not touching the switch underneath the button. So it’s better to show the handset to the Service Center. May be there are chances to replace the button.

    • http://www.unlockwindows.com arvindk

      Which version are you using and is it your phone in warranty yet. If your phone is not in warranty then please update to Windows Phone 8.1, else wait for few days as next update will be soon available on all devices officially.

      No, there is no other solution to Unlock the screen. Double tapping the screen is not yet released by the Microsoft .
