1. If the device remains unresponsive or does not turn on (or power on), reset your device.
2. If there is no video or if the screen remains black, verify that the device has enough charge to turn on:
   1. If you are using an iPad, ensure that it's connected to the USB Power Adapter supplied with the device.
   2. Let charge for at least twenty minutes, then see if it starts normally.
   3. If there is no image on the screen, press the Sleep/Wake button to attempt to wake the device.
   4. If the screen displays a red battery icon, continue charging the device until the battery is fully charged.
3. If the above steps do not resolve the issue, or the if the screen remains black or shows a persistent Apple logo, try restoring with iTunes:
   1. Connect the device to your computer and open iTunes.
   2. If the device appears in iTunes, select and click Restore on the Summary pane. Learn more aboutrestoring iOS software.
   3. If the device doesn't appear in iTunes, try to force the device into recovery mode, and then restore it.

Best of luck,

Mario
