Hi @CarloAccetta

Welcome to the HP Support Community. 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did you make any changes to the settings of your PC prior to the issue?
• Did this happen after a recent window or software update?
• Have you made any hardware/software changes?

While you respond to that, let's try these steps: 

Shut down the computer.

Press the Power button, and then immediately press the Esc key repeatedly to open the Startup Menu.

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.
