Hi @harsh32015 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for explaining the issue—I'm really sorry your laptop’s Ctrl key is behaving erratically. That kind of behavior can be especially disruptive, especially if the key is auto-triggering or interfering with your work. 

Let’s walk through a focused recovery path to help restore normal keyboard function.

Step-by-Step Fix for Ctrl Key Malfunction

 

1. Clean the Key Area

• Power off your laptop completely.
• Use a soft brush or compressed air to gently clean around the Ctrl key.
• Press and release the key several times to check for physical sticking.

Dust or residue under the keycap can cause false triggers or stuck behavior.

 

2. Run HP Keyboard Diagnostics

• Restart your laptop and press Esc, then F2 to open HP PC Hardware Diagnostics.
• Select Component Tests > Keyboard Test.
• Follow the on-screen instructions to test each key, including Ctrl.

This helps confirm whether the issue is hardware-related.

 

3. Update or Reinstall Keyboard Driver

• Press Windows + X, select Device Manager.
• Expand Keyboards, right-click your keyboard, and choose Uninstall device.
• Restart your laptop—Windows will reinstall the driver automatically.

This clears any corrupted driver files that may affect key behavior.

 

4. Check Accessibility Settings

• Go to Settings > Accessibility > Keyboard.
• Turn off Sticky Keys, Filter Keys, and Toggle Keys.

These features can interfere with normal key behavior if accidentally enabled.

 

5. Test in Safe Mode

• Press Windows + R, type msconfig, and press Enter.
• Go to Boot > Safe Boot > Minimal, then restart.
• Test the Ctrl key in Safe Mode.

If the issue disappears in Safe Mode, it may be caused by a background app or system conflict.

 

6. External Keyboard Test

• Connect a USB keyboard and test the Ctrl key.
• If the external keyboard works fine, your laptop’s key may be physically damaged and require service.

Let me know what happens after the hardware test and Safe Mode check—I’ll guide you further based on that. You're doing everything right by catching this early.
