That's no good! karmentrenice, I'm always rely on my phone to stay connected with family and friends and don't know what I'd do if it didn't turn. So I can definitely understand your concern.
Is the LED charging indicator ON when the device is connected to charger? Does the battery icon indicates the device is charging? Have you tried an alternate hard reset?
You may need to perform an alternate hard reset. Below I have provided the steps:
1. Press and hold down the Power Key (upper-right corner).
2. Select Power Off.
3. Press and hold the volume down key then briefly press the Power / End key.
4. When the HBOOT screen appears, release the volume down key.
5. Press the volume down key to select Factory Reset then press the Power / End key.
If your phone does not turn on after the hard reset we may need to look into replacing options. Please post back if you need further assistance.
