Press and hold the Power button for approximately 10 seconds or until the device power cycles. If the device doesn't power on or is unresponsive, attempt the following:
Plug the device into a manufacturer approved wall charger and wait 1-2 minutes.
The LED indicator should glow solid amber/red.
Third-party chargers may not work to recover the device when it is in a no power state. When attempting to recover a device that won't power on, only use the included wall charger to ensure best results.
If the LED indicator doesn't light up after 1-2 minutes, move the wall charger to a different outlet to ensure the issue isn't with the outlet.
If the device still doesn't power on, ensure it's still connected to the wall charger then press and hold the Power button (bottom button on the right-edge) and both Volume buttons (located above the Power button) for 1-2 minutes.
If the device still doesn't power on, repeat steps 1-3 using a different charger.
