Soft Reset:

1. Hold the power switch for twenty seconds. You will need to slide the power switch along and hold it for twenty seconds before releasing it. ...
2. Your reboot screen should appear when you release the power switch.
3. Give your device time to reboot for a minute or two.
4. Turn the Kindle Fire HD back on

Try rebooting. Press and hold the power button, ignoring the "Shut down" prompt until the unit turns off. Release and then press the power button for a second or two until it starts rebooting.

If that doesn't work, please repost your question, including what happens (or not happens) after the reboot.

Hold the power switch for 20 seconds. Slide the power switch and hold it in place for 20 to 30 seconds before releasing it.

• You need to physically hold the power switch in its off position for this long. Doing so tells your device to "reboot," in essence, instead of merely shutting down.
• The reboot screen should appear as soon as you release the power switch.

Give the Kindle time to reboot. The Kindle will reboot within a minute or two. Be patient and give your device ample time to finish its reset.

• There is some possibility that the Kindle will freeze as it reboots. This may be the case if your Kindle stays frozen on the reboot screen for more than ten minutes.

Charge the Kindle. If the device freezes during the reboot or does not respond to the reset at all, plug the charger in and allow your Kindle to charge for 30 minutes or more.

• Make sure that your Kindle has enough time to complete a full charge.

Hold the power switch down again. After you finish charging the Kindle, slide the power switch and hold it down for another 20 seconds.

• The reboot screen should appear again. Give the device a minute or two to reboot before checking it again. This should complete the reset.

Rebooting is easy. It is called a hard reboot. Just hold both buttons down until you see a red slider, and then slide it to shut down. It will restart, and you will see the Apple logo.

Turn the tablet all the way off, press and hold the VOL - and power at the same time for 8 to 9 seconds, it will show a green android guy with a system recovery menu. Use vol - to go down to Wipe Data/Factory Reset, press the power button to select it, go down to 'yes' to confirm, press the power button to select it, it will wipe the tablet, you then press the power button on 'reboot system'.

By holding the power button down for about 10 seconds it rebooted

Keep your finger pressed on the power button and it will shut down
