Suddenly Ctrl+Z,X,C,V and Ctrl+Shift combination shortcut keys are not working

[Khalek]

Suddenly Ctrl+Z,X,C,V and Ctrl+Shift combination shortcut keys are not working. Individual keys are working pretty fine. Checked with HP PC Hardware Diagnostics. Keyboard is working fine else. What could be the issue and what is the solution?

Welcome to the HP Support Community!

I assure you I will try my best to get this sorted.

In order that I may provide you with an accurate solution, I will need a few more details and I would appreciate if you could, perhaps elaborate on your concern.

• What is the product number of your computer?
• In which application/software these keys are not working?
• Have you checked these key combinations on a notepad?
• Have you made any software or hardware changes on the computer? 

Look forward to hearing from you and you have a great day!

Take care.

Cheers!

@Khalek Did you check if the issue occurs on an external keyboard?

While you respond to that, here's what you need to do:

I recommend you attempt the below steps to identify the cause of the failure and resolve it accordingly:

• Try changing the keyboard layout/language and check if it works: Click here for 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, perform an interactive hardware test on the keyboard using the steps mentioned on this link: Click here (look under "Running Component Tests > Keyboard test").

Let me know how that pans out,
