Help! My dad's nokia lumia 720 turned off unexpectedly after charging it. After it got to full charge i unplugged it and left it on the table. When my dad went to use it it didnt respond: the screen remained black een after pressing the lock button. We even tried a soft reset but then we worked out that it wasnt even on and it was dead. We couldnt turn it on either.... After that i plugged the phone into my pc and used the windows phone app to check status of the phone. it showed that it was charging! I thought that the phones couldnt charge when they are off! Anyway, there are no lights coming of the windows key, the back key or the search key....Please Help!!

Generally to restart your phone, simply press and hold the Volume Down button and the Power button for 10-12 seconds, until you feel the phone vibrate. This should restart your phone without deleting any of your data or apps.

Hi 413x4nd3r H03k!

Thank you for writing on the Windows Phone 8 forum.

If I have understood the issue after you put on charge your Lumia 710 it hasn’t worked any more.

Are you sure your phone has been charged. It is behaving like the battery is totally discharged.

If you keep having the same problem tough you have left the phone on charge for several hours I would suggest you to try the steps which are described on the following link.

Goodbye, Salvatore S.
