phone has gone dead, has been connected to charger for 2 hours, still dead

[DonnaMeth]

My phone went dead earlier today.  I plugged it into the charger 2 hours ago. It is still dead. Any advice?

Is it an older device?  May be time for a replacement.  If not, and it's less than a year old, it should still be covered under the manufacturers warranty and customer service can send you a replacement.

Try pressing the volume down and power buttons together for about 10 seconds and see it that helps.
