Hi @Gene1820,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

I'm sorry to hear you're having trouble with your keyboards. Let's try a few steps to troubleshoot and potentially fix the issue.

Basic Checks

1. Restart Your Computer: Sometimes a simple restart can resolve hardware recognition issues.
2. Try Different Ports: If your keyboards are USB, try plugging them into different USB ports.
3. Check the Keyboards: Ensure that the keyboards work on another computer to confirm they're not faulty.

Device Manager Steps

1. Uninstall and Reinstall Keyboard Drivers:
   • Open Device Manager (you can search for it in the Start menu).
   • Expand the Keyboards section.
   • Right-click on your keyboard device and select Uninstall device.
   • Restart your computer. Windows should automatically reinstall the driver.
2. Update Drivers:
   • Right-click on the keyboard in Device Manager.
   • Select Update driver and then Search automatically for updated driver software.

BIOS Check

1. Access BIOS:
   • Restart your computer and enter the BIOS setup (usually by pressing F2, F10, DEL, or ESC during boot, depending on your model).
   • Check if the keyboard works in the BIOS. If it does, the issue is likely with the Windows software.
2. Reset BIOS Settings:
   • In the BIOS, find the option to reset to default settings (usually labeled as "Load Default Settings" or something similar).

Windows Troubleshooting

1. Run the Keyboard Troubleshooter:
   • Go to Settings > Update & Security > Troubleshoot.
   • Select Keyboard and run the troubleshooter.
2. Check for Windows Updates:
   • Sometimes, Windows updates include fixes for hardware issues. Go to Settings > Update & Security > Windows Update and check for updates.

Power Management Settings

1. Disable USB Selective Suspend:
   • Go to Control Panel > Power Options > Change plan settings (next to your selected plan) > Change advanced power settings.
   • Expand USB settings > USB selective suspend setting and set it to Disabled.

Software Interference

1. Safe Mode:
   • Boot into Safe Mode (hold Shift while clicking Restart, then go to Troubleshoot > Advanced options > Startup Settings > Restart > press 4 to enable Safe Mode).
   • Check if the keyboard works in Safe Mode. If it does, there may be software or drivers interfering with the keyboard in normal mode.

System File Check

1. Run SFC and DISM:
   • Open Command Prompt as an administrator.
   • Run the following commands one by one:
     • sfc /scannow
     • DISM /Online /Cleanup-Image /RestoreHealth

Hardware Check

1. Internal Connection:
   • If you're comfortable opening your computer, check if the internal USB connections (for desktop PCs) are secure.

External Factors

1. Interference: Ensure there are no other electronic devices nearby that might be interfering with the USB connection.

Final Steps

• Use an External USB Hub: Sometimes using an external powered USB hub can help bypass motherboard-related USB issues.
• System Restore: If the problem started recently, you might try restoring your system to a previous point where the keyboard was working.

I hope this helps.

Take care and have a good day.
