Hi, I am Dave, I will help you with this.
1
Open Command Prompt, then run this command and press Enter:
msdt.exe -id KeyboardDiagnostic
Run that Keyboard Troubleshooter to see if that can solve the problem.
2
If that does not resolve this for you
Open Device Manager
Expand the Keyboards section
Right click your keyboard and choose 'Uninstall'
Then restart your laptop.
3
If the problem is still not resolved:
Bring up the on-screen keyboard, are those keys working correctly on that keyboard?
Connect another external keyboard to your system, are those keys working correctly on that keyboard?
If both those keyboards work correctly, there is a hardware issue on your keyboard and it will need to be replaced.
