@alexjob2000 Thank you for posting on the HP Support Community.
I appreciate your efforts to try and resolve the issue. Let's try uninstalling and reinstalling the keyboard.
Shut down the computer.
Press the Power button, and then immediately press the Esc key repeatedly to open the Startup Menu.
NOTE: If the Startup Menu screen does not open, the integrated keyboard hardware is not working. Service or replace the integrated keyboard in the notebook. To continue using the notebook, connect a USB wired keyboard to a USB port, and then restart the computer.
Press F10 to open the BIOS settings.
Press F5 to load the default settings, and then press F10 to accept the changes.
Restart the computer.
In Windows, search for and open Device Manager.
Click View, and then select Show hidden devices.
Click the arrow next to Keyboards, right-click the keyboard name, and then click Uninstall to remove the device from Windows.
Remove all devices in the Keyboards category, and then restart the computer.
The keyboard should now work correctly.
Hope this helps! Keep me posted for further assistance.
