I can't unlock the screen, so I can't press any buttons.
I'm sorry, did you try my suggestion yet? The buttons are physical (not on the screen.) Please click on the image below for the location of the two buttons: Home and Power:
Please press and hold both the Power button and the Home on the iPad buttons together for at least 10 seconds, until the Apple logo appears, then wait a bit, then check.Please let me know if it works or not. I will help further as needed. Thank you
What buttons? Where are they on the pad?
You're dealing with a geriatric here!!
I'm sorry. If you click on the image / picture below I gave you previously, then it will show you the buttons. Basically, the POWER button is located at the top side to the right, and the HOME button is located right below the screen in the middle.
Now I can't unlock the screen!
