Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
Welcome to the HP Forums. I would be happy to help you with your Slate 7. I understand that it freezes and you have already done some preliminary troubleshooting.
Don't worry though as I have a few steps to determine the issue and find a solution as well,
Perform a hard restart to unlock the tablet. Press and hold the power button for more than eight seconds. After the tablet fully shuts down, press the power button again to restart.
Click here and refer the document for more information.
Let me know if that works.
