please follow the steps below->
1. Plug-in your charger. Sometimes the Kindle battery can get run-down enough so that it will "freeze." Plugging the charger in and giving your Kindle battery some much needed power often will un-freeze the screen.
2. If that doesn't work, try what is called a "soft reset." To do a soft reset on your Kindle press the , , and keys simultaneously. Your Kindle screen should go blank or dark and then slowly come back to life.
3. When doing a soft reset doesn't work, you will occasionally have to do a "hard reset." To do a hard reset - - Make sure your Kindle's battery is charged (about an hour of charging time should do it) - Remove the charger cord from your Kindle - Open the back of your Kindle - Locate the small hole under the word "Reset" - Open a small paper clip - Insert the paper clip end into the hole and press GENTLY for about 10 seconds - Your Kindle screen should go blank (or black) and then the Kindle should re-start
4. When a hard reset doesn't work you can try to remove and replace the battery in your Kindle. This is a bit more complex but not too difficult - - Turn your Kindle off - Remove the charger cord from your Kindle - Open the back of your Kindle - Locate the gray battery, and the finger-notch for removing the battery - Gently press the battery toward the back of its compartment, then lift the battery out - Locate the connector that attaches the battery to the Kindle - GENTLY pull the battery connector out of the Kindle - With the battery out of the Kindle turn it on for about 5 seconds - Replace the battery and close the back cover of your Kindle - Turn the Kindle on
If your Kindle is still "frozen" after completing the steps above, your next move is to contact the Amazon Kindle support team.
Go to your Amazon account page - select "Manage my Kindle" and contact the support team from there. You can find the link at the top of the "Manage my Kindle" page on the far right side.
i hope this will resolve your problem
