Anyone ever have a similar problem?
First, unplug the charging cord, wait 5 seconds, and plug it back in. Does it display the charge level? If not, the phone might have a dead battery as a consequence of the charger having failed or being plugged into an outlet that has been switched off. If you do see the charge level is it at least 20%?
Second, if you do see the charge level press and hold the power button for as long as 2 minutes. There is more troubleshooting information here:
