Sometimes your Kindle can be unresponsive (won't charge) and keep you from using the device properly (the most important reason for this issue can be glitch in the software). If there is no hardware issue on the device, some of the solutions below should resolve this issue.

Please follow the steps below to reset your device:
1. Press and hold (or slide and hold) the power button for exactly 45 seconds.
2. After 45 seconds, release the power button.
3. Wait 2 minute, then turn on your Kindle.
4. Test your Kindle (try to charge it).

Please try this procedure at least 3 times (if you have leather cover or any other cover remove it).

If the previous procedure doesn't work, perform the procedure below:
1. Plug the Kindle into the charger for 5 minutes.
2. After 5 minutes (while still plugged in) press and hold power (slide and hold) button for 45 seconds.
3. Allow up to 3 minutes for the Kindle to reboot.
4. Test your Kindle (try to charge it).

Another solution for this kind of issue:
1. Connect the USB cable to computer (do not connect Kindle).
2. Hold the Power button for 20 seconds.
3. After 20 seconds while still holding Power button, plug the other part of the USB cable in the Kindle.
4. Leave the Kindle for 2 minutes and try to turn it on (hold the Power button for exactly 45 seconds).
5. Test your Kindle (try to charge it).

Please try all solutions (step by step) and let me know if that works.

If none of those solutions works or you need more information please do not rate my answer negative BAD service or POOR service. Reply to me using "Reply to Expert" button and I'll provide you with the next step.

Kind Regards,
Todd
