What can you do when your Kindle won’t turn on or is unresponsive, or appears frozen:
Recharge your Kindle using the power adapter that came with the device and plug it into an AC outlet. Make sure that the charging light next to the micro-USB port lights up while you are charging. Allow the device to be charged in this manner for at least 30 minutes.
Slide and release the power switch. If your Kindle does not turn on then try resetting it by doing the following:
1. Disconnect your Kindle from any power source.
2. Slide and hold the power switch for 15 seconds, then release.
Note that the screen will be blank for about 30 seconds while your Kindle restarts.
