If your iPad mini stops responding to the keyboard in apps such as Notes and Safari, use the steps below to try to resolve the issue. Test the keyboard between each step to see if it's working again.

To pair your iPad mini with your keyboard folio:
Power your keyboard off, and then back on, using the power switch on the right side of the keyboard.

Restart your iPad mini by pressing and holding the Home and Sleep/Wake buttons together until the screen goes blank (wait for the iPad mini to reboot).
