@Sommers89, Welcome to the HP Support Community!

If your tablet does not start normally, it might be necessary to perform a reset without turning on the tablet.

CAUTION: All data saved on your device is deleted when you perform a factory reset. All apps are uninstalled. Data stored in your Google Account can be restored. Back up all important files, either on the Web or with an external storage device, before resetting the tablet.

Use the following steps to begin the factory reset:

1. Charge the tablet for at least half an hour, and then disconnect the charging cable from the tablet.

2. If you have a microSD card installed in the tablet, remove the memory card before resetting the tablet.

3. Select your tablet model from the list below to view instructions for resetting the tablet.

Most probably the issue will be with the OS or Harddisk.
