Welcome to HP support community.

Did you drop liquid or have any accidents with the keyboard? 

Did you check with an alternate user account or an external keyboard to check if all the keys on that work? 

  

I recommend the below steps: 

Clean the keyboard with compressed air (blow compressed air in the gaps between keys). This removes some lint and dust.  

Shut down the laptop, remove the battery and cable for a moment, press and hold the start button for 60 seconds 

Replace the battery, restart the notebook, 

if the issue persists, change the keyboard layout and check if it works: Click here for steps. 

Also, run a hardware test to identify any issues with the keyboard: Click here for details (Interactive test) under component tests - keyboard. 

I hope that helps.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
