volume down + power for 10 to 15 seconds to soft reset.

Plug it in using an original Nokia charger then use the reset key sequence.

Here is the link

Press and hold the Volume down Volume down button and Power Power button buttons at the same time until you feel a vibration (about 10–15 seconds).

When you feel the vibration, immediately press and hold the Volume down Volume down button button until you see a large exclamation mark.

Once the exclamation mark appears, press the following four buttons in this order: Volume up Volume up button, Volume down Volume down button, Power Power button, Volume down Volume down button. Your phone should now reset and restart itself. (It might take a while for the reset to finish.)

I've found with my partner's phone (920) & mine (820), sometimes the OS and battery don't communicate so the battery completely drains. Try plugging in a quality (or original) charger and give it half hour...

If that doesn't work, try a Hard Reset. Failing that, needs to be returned to Nokia care...
