Greetings @bjk572,
Welcome to HP Forums and Thanks for the post.
I understand that you are facing an issue with your computer where the touchscreen is not working, is that right?
Not to worry, I will be glad to assist you.
Have you tried any troubleshooting steps on your own?
May I know the operating system installed on your computer?
May I know the exact product number of your computer? Click here. Please do not share the serial number of your computer.
Request you boot the computer to recovery manager by tapping F11 repeatedly on startup.
Test the touchscreen in recovery manager.
If the touchscreen is not working in recovery manager, request you contact our phone support to check on the service options available to replace the screen on your computer.
If the touchscreen works fine in recovery manager, refer to HP Article and try the steps suggested to resolve the issue you are facing.
Keep me posted.
