tablet buttons don't work

Excuse me, the problem I have is that the keys do not work on my INSPIROY H640P tablet but the pen keys do work, I did not buy the tablet a long time ago

  • Hi Lucas, I'm sorry for the issue you're experiencing with your H640P tablet. Kindly check if the press key switch is locked.

    If it is, please unlock it by sliding it down. You can then customize your press keys on the driver and use them on your favorite software. Please let me know if you need further assistance.

    Best Regards,

  • I don't have the switch locked, it's strange that the buttons on the tablet don't work but the pen does, when I'm done using the tablet I put it in its bag and pack it up.

    Excuse me, is there a way to reset the tablet to factory settings? I tried uninstalling and installing the program but it still doesn't work and continues with my previous settings.


  • Hi Lucas, thank you for your reply, and I'm sorry your issue persists. Kindly try the following steps:
