Hi @horacam,

Welcome to the HP Support Community. 

I'd be glad to help you! 

It sounds like the keyboard functionality on your HP All-in-One Desktop PC 24-cb1000a has stopped working, and even a wired USB keyboard doesn't respond. Since the mouse works, this indicates the issue may be related to the keyboard driver or other system settings rather than a hardware malfunction.

Here are several steps to troubleshoot and fix the issue:

1. Restart the PC

• Restarting can sometimes resolve hardware recognition issues.
• If you're unable to use the physical keyboard, use the on-screen keyboard to navigate and restart the system:
  • Press Ctrl + Alt + Delete on the on-screen keyboard.
  • Select the Power icon in the bottom-right corner and click Restart.

2. Check the USB Ports

• Try plugging the wired USB keyboard into a different USB port.
• If the keyboard is plugged into a USB hub or extension, connect it directly to the PC to rule out any issues with the hub.
• Test if the keyboard works on another device (like another computer) to ensure it’s functioning properly.

3. Uninstall and Reinstall Keyboard Drivers

There might be a problem with the keyboard driver. Try reinstalling it:

1. Press Windows + X on the on-screen keyboard and select Device Manager.
2. Scroll down and expand Keyboards.
3. Right-click on the keyboard driver (look for a name like HID Keyboard Device or Standard PS/2 Keyboard) and select Uninstall device.
4. After uninstalling, restart your computer, and Windows will automatically reinstall the keyboard driver.
5. If the driver doesn’t reinstall automatically, return to Device Manager, right-click the Keyboards category, and select Scan for hardware changes.

4. Update Drivers (Chipset and Keyboard)

• Go to the HP Support page for your HP All-in-One Desktop PC 24-cb1000a and download the latest chipset and keyboard drivers.
• Install the updated drivers and restart the system.

5. Run the HP Hardware Diagnostics

• HP devices come with built-in hardware diagnostic tools. To test whether there’s a hardware issue with the keyboard:
  1. Restart your PC and press F2 repeatedly as it boots up to open the HP Diagnostics tool.
  2. Run the Component Test for the keyboard to check for hardware problems.

Hi @horacam,

Please find the remaining steps below.

6. Check for Windows Updates

Sometimes, missing or outdated updates can cause devices to stop working:

1. Go to Settings > Update & Security > Windows Update.
2. Check for and install any pending updates, especially if they include driver updates.

7. Check for BIOS Update

Occasionally, a BIOS update can help resolve hardware detection issues.

1. Visit the HP Support page for your specific model.
2. Check if there is a BIOS update available for your All-in-One PC.
3. Follow the instructions to download and install the update if available.

8. Check for Sticky/Filter Keys

It's possible that accessibility settings may have been turned on accidentally, which could affect keyboard functionality:

1. Go to Settings > Ease of Access > Keyboard.
2. Make sure Sticky Keys, Filter Keys, and Toggle Keys are all turned off.

9. Test in Safe Mode

To rule out software conflicts, try booting into Safe Mode:

1. Press Windows + R on the on-screen keyboard, type msconfig, and press Enter.
2. In the Boot tab, check the box for Safe Boot, then click OK and restart.
3. Once in Safe Mode, check if the keyboard works. If it does, this indicates a software conflict, possibly from a recently installed program or driver.

10. System Restore

If the issue started recently, you can use System Restore to revert the system to a point when the keyboard was working:

1. Press Windows + R on the on-screen keyboard and type rstrui to open System Restore.
2. Follow the prompts to restore your system to an earlier date when the keyboard worked properly.

Hope this helps! Keep me posted for further assistance

Thanks for your input I had tried all of it before and it didnt' work. I found this online and option 2 fixed the problems! https://answers.microsoft.com/en-us/windows/forum/all/keyboard-not-working-at-windows-login-screen/7...

I may enable some of those keyboard features one at a time and see which one is broken!
