Symptoms

Your iPhone, iPad, or iPod touch may occasionally stop responding to buttons, switches, or touchscreen input and may exhibit one or more of these symptoms:

  • Does not return to the Home screen after you press the Home button
  • Does not wake from sleep after you press the Sleep/Wake button
  • Does not turn on (or power on) when you press any button
  • Does not start up past Apple logo
  • Appears frozen or unresponsive
  • Is unable to “Slide to Unlock” or “Slide to Power Off”


Resolution

  1. If a single application is not responding or stops responding when it opens, you can force it to close.
  2. If the device is unresponsive or if certain controls aren’t working as expected, restart your device.
  3. If the device remains unresponsive or does not turn on (or power on), reset your device.
  4. If there is no video or if the screen remains black, verify that the device has enough charge to turn on:
    1. Ensure that the iPad is 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.

Additional Information

Tip: To isolate an issue related to a portion of the Multi-Touch display, follow these steps:

  • Open the Maps application and double-tap each corner, then the center, to verify that it zooms in to each section.
  • If a specific area is affected in another application, note the location and try to verify touch functionality for that location in the Maps application.
