If your iPad screen frozen and won’t turn on, first ensure it’s charged by plugging it into a charger for at least an hour. If it still doesn’t respond, try a force restart: for iPads without a Home button, press volume up, volume down, and hold the top button. For iPads with a Home button, hold both the Home and top buttons. If that doesn’t work, connect your iPad to iTunes or Finder for recovery, or contact Apple Support for assistance.
