Hi, there I am Cris and will be glad to assist you.
If your iPad is plugged into the charger unplug it for 30 seconds.
Plug the iPad back into the charger and wait about 2 minutes. After 2 minutes press and hold the Home button and Top button down together at the same time.
Continue to hold for up to 1 minute or until you see the Apple logo appears. When it does allow the iPad to boot up and leave on charger until fully charged.
Let me know how this solution works for you and if we need to continue troubleshooting. The process can take 2-3 tries for it to work.
If the solution works please take the time to rate my service and submit at the top.
