Kindle Fire HDX “Hard Reset”
At times tablets, like all electronics, will misbehave. If your Kindle Fire tablet ever freezes up or just begins a strange behavior, your first response should be a “hard reset,” which basically forces your tablet to shut down and reset itself.
To hard reset your Kindle Fire HDX, simply hold down the power button until your tablet asks, ‘do you want to shut down your Kindle?’. Tap YES, and wait for your tablet to shut down. Then press and hold the power button until the words ‘kindle fire’ appear on the screen. Release the power button and allow the tablet to finish restarting.
