Recalibrate iPad Home Button

A reoccurring problem with the iPads is the home button not working.  Here are step-by-step instructions on how to recalibrate the home button.  This is usually a temporary fix and sometimes does not always work, but a lot of times this fixes the problem!

Step 1: Launch one of the stock apps on your iDevice (Weather, iTunes, Stocks, etc.).

Step 2: Press and hold the power button until you see the “slide to power off” prompt, then release the power button.

Step 3: Press and hold you home button until the the “slide to power off” prompt disappears and the app force quits.

If this doesn't work, you can also go to Settings --> General --> Accessibility --> and turn on AssistiveTouch under Physical & Motor.  This will put a home button on screen for students to use.
