View this info if your device is unresponsive, frozen or won't power on or off.
This device has a non-removable battery. This process can be used to simulate a "battery pull" when the device is unresponsive, frozen, or doesn't power on.
In most cases, a soft reset won't affect data on the device, unless the battery is very low.
Press and hold the Power/Lock button (on the right edge) for approximately 20 seconds or until the device power cycles.
Press the Power/Lock button again for 2-3 seconds to restart the device.
If the Power button method doesn't work, charge the device for a minimum of 4 hours using the supplied charger or 12 hours if using a different charger.
Refer to Power & Charging Issues - Non-Removable Battery Devices for additional info on resolving power issues.
