Thanks for the update.
- Try to download and install the keyboard driver directly from the HP support website. https://support.hp.com/us-en/drivers/hp-elitebo...
- If the problem persists, try pressing the Scroll Lock key once, then check if the keys are working.
- If the problem continues, I recommend performing Repair Install Windows 10 with an In-place Upgrade, which will update your device to the latest version and resolve any problems without removing any files.
Detailed steps here: https://answers.microsoft.com/en-us/windows/for...
- If none of the steps worked, it could be a PC feature with the specific make and model that needs to be enabled or possibly a problem with the hardware. In this case, I suggest connecting with HP support for further testing.
Thank you.
