Hello Alison! Thank you for your question. I am a licensed computer professional with over ten years of experience, and I will be assisting you today.I'm sorry about the issue. You may have damaged the iPad internal hardware since it was dropped, but can you please try to restart the iPad the following way, and see if it works: Please press and hold both the Power button and the Home buttons together on the iPad for at least 10 seconds, until the Apple logo appears, then wait a bit, then check, then check.
Edit: Please let me know if you still need help with this. Thank you,
