Restart the Laptop: Sometimes, a simple restart can resolve temporary glitches that cause keyboard keys to malfunction.
 

Clean the Keyboard: Dust and debris can accumulate under keys and cause them to stop working. Carefully clean the keyboard by blowing air over it or using a can of compressed air.

Check for Software or Driver Issues:

• Go to Device Manager by right-clicking the Start button.
• Expand the Keyboards section, right-click on your keyboard device, and select Uninstall device. After this, restart your laptop, and Windows should reinstall the driver automatically.
• If this doesn’t help, go to the HP Support website and download the latest keyboard driver specific to your model.

Run the Keyboard Troubleshooter:

• Go to Settings > System > Troubleshoot > Other troubleshooters.
• Select Keyboard and run the troubleshooter.

Check for Windows Updates: An update might fix bugs or glitches causing the issue. Go to Settings > Windows Update and check for any available updates.

Test in Safe Mode:

• Boot your laptop into Safe Mode. If the keys work in Safe Mode, it could be a software conflict. Uninstall recent software or updates that might be causing the issue.

Use an External Keyboard: If an external keyboard works fine, it may indicate a hardware issue with your laptop's built-in keyboard.
Please run the hardware test please follow the steps mentioned in this document: HP PCs - Testing for hardware failures in Windows
