iPad Air not working

For older iPad models with a Home button, do a hard reset of your iPad by holding down both the Home and sleep/wake buttons simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.

OR

For much newer, larger screen iPad models, without a Home button, try the new hard reset procedure for the new 2018/2020/2021 iPad Pros and the 2020 iPad Air 4 models.

1. Press and Release the Volume Up button.

2. Then immediately Press and Release the Volume Down button.

3. Then, Press and Hold the Power Button at the top. You will see the Slide to Power off button, but keep on holding down the Power Button until you see the Apple logo, then let it go.

Once you have performed all the steps, wait for a few seconds and your 2018 iPad Pro will boot up completely to the iPad Pro’s Lock screen.

Best of Luck to You!

There are 4 models of iPad Air. Which one do you have/own?
