Step 1: Charge the battery
Charge the battery using the charging cable that came with your tablet. Allow the battery to charge for 30 minutes or more, and then try to turn on the tablet again.
Step 2: Find a fix that matches the symptom your tablet is experiencing
Read from the following list of symptoms. If you find a symptom that describes the condition of your tablet, then follow those instructions. If you cannot find a symptom that matches the condition of your tablet, then continue to
Error screen displays
If an error message displays on the screen, write down the error message exactly as it appears. Search the Internet using the exact text from the error message to find a solution.
Some error screens do not include an error message. You might see a black screen with a green robot and red caution icon:
To restore the tablet to working condition when this error screen appears, press and hold the power button for more than eight seconds. After the tablet fully shuts down, wait a few seconds, and then press the power button to turn on the tablet. If the tablet turns on normally and the error screen does not reappear, you are done. If the error screen reappears, perform a factory reset on the tablet. Refer to Performing a Factory Reset on Your HP Tablet for instructions.
The tablet does not turn on
If the screen is black and does not respond when you push the power button, follow these steps:
1. Verify that you are using the correct charger for the tablet .
Using a charger from another source, such as a cell phone charger, might cause the tablet to charge slowly, or it might not charge at all. Charge the tablet using the AC adapter that came with your tablet.
2. Verify the tablet is receiving power from the AC adapter .
Verify that the AC adapter is not damaged, and that it is connected correctly to a working wall outlet plug. Examine the AC adapter, wiring, and connector for damage.
3. Use a different AC power adapter .
If you have access to a different AC adapter that is designed for the tablet, connect it and try to start the tablet.
4. Remove the AC adapter and boot on battery power only .
A defective AC adapter might not charge the battery, and can prevent the tablet from booting on battery power only. To verify that battery power is available for the tablet, connect the AC power adapter and allow the battery to charge for 30 minutes or more. Disconnect the power adapter and press the power button.
• If tests of both the battery and the AC adapter fail, there might be a problem with the tablet requiring service by HP.
• If the tablet boots, the AC adapter might need to be replaced.
5. Charge the tablet for five hours or longer .
Leave the tablet plugged into an AC adapter for five hours or longer. After five hours of charging, disconnect the charging cable and try to turn on the tablet.
If the tablet still does not turn on, boot into the Android system recovery menu, and select Restart now to restart the tablet. For instructions to access the Android system recovery menu on your tablet, seePerforming a Factory Reset on Your HP Tablet .
6. Plug the AC adapter into a different power outlet and try to turn on the tablet.
Step 3: Perform a hard reboot
A hard reboot can resolve many startup issues. Press and hold the power button for more than eight seconds. After the tablet fully shuts down, wait a few seconds, and then press the power button to turn on the tablet.
If the tablet does not start, continue with the next step.
Resetting with the tablet powered on
1. If you have a microSD card installed in the tablet, remove the memory card before resetting the tablet.
2. From the Home screen, touch the All apps icon, and then touch the Settings icon.
3. In the Personal section, touch Backup & reset.
4. Touch Factory data reset.
5. Touch Reset tablet.
6. If you set a lock screen password for your tablet, enter your password when prompted.
7. Touch Erase everything to confirm and begin the reset.
1. The tablet powers off and the screen shows Erasing. When the reset is complete, the tablet reboots. Set up the tablet by following the steps in the HP support document Setting Up Your HP Tablet .
