Thank you for posting on the HP Support Community.

• Did you make any changes in the settings of your PC prior to the issue?
• What are the troubleshooting steps you have tried so far?
• Have you tried using the external keyboard?

Don't worry as I'll be glad to help,  I have a few troubleshooting steps we could try to fix the issue:  
Use HP PC Hardware Diagnostics to complete functional test of the keyboard and identify any problems with the hardware.

1. Download the latest version of HP PC Hardware Diagnostics.

2. In Windows, search for and right-click HP PC Hardware Diagnostics for Windows, and then select Run as administrator.

   

3. Click Component Tests, click Input Devices and then select the Keyboard Test.

   

4. Click Run once to begin the test.

   The test ends when you complete the tasks or after 3 minutes.

For more information about using the HP PC Hardware Diagnostics for Windows, go to HP PCs - Testing for Hardware Failures.
 

Hope this helps! Keep me posted for further assistance.
