Hi @GK400F1,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

Sorry for the inconvenience caused don’t worry let me help you.

Recommended Steps

1. Clean the Keyboard
   • Turn the keyboard upside down and gently shake out any debris.
   • Use compressed air around the malfunctioning key.
2. Test on Another Device
   • Connect the GK400F to another PC to confirm whether the issue is hardware-related.
3. Update Keyboard Software / Drivers
   • If you’re using HP keyboard software, check for latest updates.
4. Key Replacement (if available)
   • Some GK400F models allow individual key switches to be replaced, though this is more advanced.

I hope this helps.
