Amazon Fire HD 10 - Black

If the screen on your Fire tablet is frozen, or your device is unresponsive in general, restart it.

• Press and hold the Power button for 40 seconds or until the device restarts automatically. 
• If your device restarts automatically before 40 seconds has passed, release the Power button. If your device does not automatically restart after 40 seconds, press the Power button to turn it on.

Confirm that your device is connected to the Internet, either through Wi-Fi or through a mobile connection, such as 4G, if enabled for your device. Your device must be connected to the Internet to buy and sync content or to download content from the Cloud. Check the status of your wireless connection from the status bar at the top of the screen. The Wi-Fi icon will indicate the strength of your wireless connection. A mobile connection will show LTE, 4G, 3G, EDGE, or GPRS. If you are in an area with a poor Wi-Fi signal, try turning it off and back on, or selecting a different Wi-Fi network.

Verify that your device is registered to the correct Amazon account. If you have multiple household profiles on your Fire tablet, make sure that you are in the correct profile. To verify that you are in the correct profile, swipe down from the top of the screen and tap the profile icon in the upper right corner of the Quick Settings menu. If the wrong profile is selected, tap the correct profile to open it. To verify that your device is registered to the correct account, swipe down from the top of the screen and tap Settings and then tap My Account. If you see the wrong account listed, tap Deregister, and then tap Deregister again to confirm. After you deregister your device, tap Register to register your Fire tablet to the correct account. If your device is registered to the correct account, confirm that your device is connected to a wireless network. Then, swipe down from the top of the screen and tap Sync Device. 

Note: Content over 50MB can't be downloaded over a mobile network connection.

Swipe down from the top of the screen and then tap Settings > Apps & Games > Manage All Applications > All. You can clear data, clear cache, force stop, or uninstall the application if you are having problems with it. 

Note: Amazon applications, such as Silk Browser, cannot be uninstalled from your device. If you clear data, it won't delete the app; however, saved information such as game scores or account information may be lost or need to be re-entered. 

Tip: Quickly force stop an app by accessing the Task Switcher. Tap the square icon in the Navigation bar at the bottom of the screen. Tap the X or swipe away any item to force stop the application.

Before you begin, make sure that: You are using the power adapter and micro-USB cable that came with your device. You are charging your device from a power outlet. Using a USB port connected to a computer will increase charging time. The micro-USB cable is securely connected to your device and power adapter. Then: 

• Unplug the power adapter and micro-USB cable from your device, and then connect them to your device again. 
• Insert the power adapter into a power outlet. If your device doesn't indicate that it's charging, unplug the power adapter. 
• Press and hold the Power button for 40 seconds or until the device restarts automatically. If your device restarts automatically before 40 seconds has passed, release the Power button. 
• If your device does not automatically restart after 40 seconds, press the Power button to turn it on. 
• After you restart (or attempt to restart) your device, plug the power adapter and micro-USB cable into the device and charge for at least an hour. If your device is turned on, the battery indicator will look like this when your Fire tablet is charging.

To reset your Parental Controls password: Swipe down from the top of the screen and tap the Parental Controls notification. Enter an incorrect password five times.

Enter your Amazon account password (this is the password you used to register your device and to sign in to Amazon) and then tap Continue. Enter your new Parental Controls password and then tap Finish.
