Hardware reset

If the phone hardware is jammed, you should first recommend
that the consumer performs a hardware reset. The hardware
reset does not reset the Windows Live ID or remove any
consumer data. Because the consumer cannot remove the
battery to reset the phone the phone has a special electronic
circuit which cuts the phone power when the power key is
pressed for 10 seconds.
To perform the hardware reset press the Power key and hold it
for 10 seconds. The phone screen will turn black (phone is off).
Then press the Power key to turn on the phone.
