I have a KBAR211 keyboard and the cntl+c and cntl+v have stopped working. seems I turned it off????

[Islandbnd]

I have a KBAR211 keyboard and was using it with my dell all-in-one.  I  must have hit a key combo that turned off some functions such as using ctrl+ functions, the right shift key with certain letters, etc. I really like the keyboard and would love to be able to use it again. For instance, using the left shift key and the letter D works but the right shift key and the letter d doesn't work at all, not  even to display a d?
Any suggestion would be appreciated. Thanks.

@Islandbnd, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
It sounds like your HP KBAR211 keyboard may have had some of its modifier key functions (like Ctrl and Shift) unintentionally disabled or remapped. This can sometimes happen due to accidental key combinations or software glitches. Here’s a step-by-step guide to help you troubleshoot and hopefully restore full functionality:

Check for Sticky or Filter Keys (Windows Settings)

Sometimes accessibility features like Sticky Keys or Filter Keys can interfere with keyboard shortcuts.

• Press Windows + I to open Settings
• Go to Accessibility > Keyboard
• Make sure Sticky Keys, Filter Keys, and Toggle Keys are all turned off

Test the Keyboard in Another Device

• Connect the KBAR211 to another PC (if available) to see if the issue persists.
• If the keyboard works fine elsewhere, the issue may be with your current system settings or drivers.

Use On-Screen Keyboard to Test Key Behavior

• Press Windows + Ctrl + O to open the On-Screen Keyboard
• Try pressing Ctrl + C and Ctrl + V using both the physical and on-screen keyboard to see if the issue is hardware or software related.

Run HP Hardware Diagnostics

HP provides a tool to test keyboard hardware:

• Download and install HP PC Hardware Diagnostics for Windows
• Run the tool as Administrator
• Go to Component Tests > Input Devices > Keyboard Test
• Follow the instructions to test each key

This will help identify if any keys are physically malfunctioning.

Reset Keyboard Settings

If a key combination accidentally changed keyboard behavior, resetting the keyboard layout might help:

• Go to Settings > Time & Language > Language & Region
• Under Preferred languages, click your language (e.g., English US)
• Click Options and ensure the correct keyboard layout is selected (e.g., US QWERTY)

Reinstall Keyboard Driver

• Press Windows + X > Device Manager
• Expand Keyboards
• Right-click on your keyboard (e.g., HID Keyboard Device) > Uninstall device
• Restart your PC – Windows will reinstall the driver automatically

Additional Tips

• If you suspect a key combo disabled functions, try pressing Fn + Esc or Fn + Left Ctrl (some keyboards use this to toggle function modes).
• You can also try resetting BIOS settings to default if the keyboard is acting up even outside Windows. 

I hope this helps. 

Take care and have a good day.
