Hello Liz! Thank you for your question. I will be assisting you today.I'm sorry about the issue. Please disconnect the cable from the ipad. Then 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.
Is there any power / light at all now?If there is still any issue, please click on the Reply to Expert tab below, and reply back to me, so I can help further. Thank you very much
