Welcome to HP Forums. This is a great place to get support, find answers and tips.
I understand that your HP 10 2101 tablet is not booting up and you have already attempted a Reset
At this point I would request you to contact our Phone Support for Service Options
1) Click on this link - www.hp.com/contacthp/
2) Click on "Continue as guest".
3) Enter the serial of your device.
4) Select the country from the drop-down.
5) Click on "Show Options".
Fill the web-form. A case number and phone number will now populate for you.
Thank you 🙂
