All-in-one desktop keyboard error

HP Recommended
23-r010
Microsoft Windows 10 (64-bit)

Came home the other day and all of a sudden the keyboard wouldn't work. I tried 4 different working keyboards from other machines and my All-in-one still wouldn't recognize any of them. Did a hard reboot and have been getting nothing but a keyboard error ever since.

HI@publishermike54, Welcome to the HP Support Community!

 

There should be an option in BIOS where you can select stop on all but keyboard failures, the only problem is you need an older PS/2 keyboard to get into the BIOS to do it.

 

Please check if you can get a PS/2 keyboard and connect it to your computer and change the settings in the bios.

 

or

 

Before you begin troubleshooting

Before troubleshooting your keyboard, complete the following steps:

  1. Some of the troubleshooting steps in this document require that you know how your keyboard connects to your computer. Find out what kind of wired keyboard you have by looking at the end of the keyboard cable and comparing it to the following images:

    Connector type

    Keyboard connector image

    USB

    PS/2

  2. If the keyboard has stopped responding, find out if the problem is with the keyboard or with the software application you are using.

    In Windows 10, press the Windows  + A key, and note what happens.

    • If the Action Center opens, the keyboard is working and the software that you are using has stopped responding. Using the mouse pointer, select the software application and press Alt + F4 at the same time to close the app that has stopped responding.

    • If the Action Center does not open, the keyboard or operating system has stopped responding. Go to Keyboard does not work (in this document) to check the connections and synchronize the keyboard to the BIOS and Windows.

       

    In Windows 8, press the Windows  + C key, and note what happens.

    • If the Charms menu opens, the keyboard is working and the software that you are using has stopped responding. Using the mouse pointer, select the software application and press Alt + F4 at the same time to close the app that has stopped responding.

    • If the Charms menu does not open, the keyboard or operating system has stopped responding. Go to Keyboard does not work (in this document) to check the connections and synchronize the keyboard to the BIOS and Windows.

Keyboard does not work

To check your keyboard connections and synchronize the keyboard to the BIOS and Windows, you will need to reset the keyboard.

  1. Press the Power button to turn off the computer.

  2. With the computer fully off, disconnect all devices connected to the computer except for the monitor.

  3. Inspect the wired keyboard connector and reconnect. Before reconnecting look at the connector on the computer to make sure there is not anything obstructing the connection in the port.

    • For USB keyboards, connect the keyboard into a USB connector on the back of the computer that was not previously used, if there is one available.

    • For PS/2 keyboards, if you find pins that are bent, try to straighten the pins with the tip of a retracted ball-point pen. If pins are bent beyond repair or are broken, replace the keyboard.

  4. For PS/2 keyboards, inspect the connector at the end of the keyboard cable. If pins are bent, try to straighten the pins with the tip of a retracted ball-point pen. If pins are bent beyond repair or are broken, replace the keyboard. Make sure no broken pins are lodged inside of the holes in the PS/2 connector on the computer. Any broken pins must be removed from the holes before another keyboard can be connected.

  5. Reconnect the keyboard. For USB keyboards, connect the keyboard into a USB connector on the back of the computer that was not previously used.

  6. Turn the computer on and press the Esc key repeatedly to open the startup menu.

    • If the setup menu opens, use the arrow keys to navigate the menus. If these keys are working in the startup menu, but then fail when Windows loads, the issue is occurring in Windows.

    • If the setup menu does not open, the wired keyboard hardware is not working. The wired keyboard may need to be serviced or replaced. Try another wired keyboard if available.

  7. With only the keyboard and monitor connected, turn on the computer. When Windows opens, do the following.

    In Windows 10, press the Windows  + A keys, and note what happens.

    • If the Action Center opens, the keyboard is now working. There was a connection problem. Press the Power button to shut down the computer. Reconnect your other devices, including the mouse.

    • If the Action Center does not open, the keyboard might be bad. Connect the keyboard to another computer to see if it is bad. Replace the keyboard if it does not work on another computer. If the keyboard works on another computer, press the Power button to shut down your computer, and continue using these steps.

    In Windows 8, press the Windows  + C keys, and note what happens.

    • If the Charms menu opens, the keyboard is now working. There was a connection problem. Press the Power button to shut down the computer. Reconnect your other devices, including the mouse.

    • If the Windows 8 Charms menu does not open, the keyboard might be bad. Connect the keyboard to another computer to see if it is bad. Replace the keyboard if it does not work on another computer. If the keyboard works on another computer, press the Power button to shut down your computer, then continue using these steps.

  8. Reconnect the keyboard to the computer.

  9. Turn on the computer.

  10. In Windows, search for and open Device Manager.

  11. Click View and select Show Hidden Devices.

    Figure : Show hidden devices

    Show hidden devices
  12. Click the arrow next to Keyboards, right-click a keyboard device name, then select Uninstall to remove the device from Windows.

    Figure : Uninstall keyboard

    Uninstall keyboard
  13. Continue removing device names in the Keyboards category until all device names have been uninstalled.

  14. Leave the wired keyboard connected to the computer, and restart the computer. Wait for the computer to restart and open Windows and user the keyboard in an application.

  15. If the wired keyboard is still not working, test the keyboard for key or hardware failures. Testing for Hardware Failures (Windows 10, 

Key presses are slow to respond

If there is a short delay from the time a key is pressed to the time the character displays on the screen, the Filter Keys function might be activated. The Filter Keys function provides a greater range of key press options to fine-tune key delays and prevent inadvertent key presses. To disable Filter Keys and return to the default keyboard behavior, use the following steps:

  1. In Windows, search for and open Settings.

  2. In the Settings, click Ease of Access.

  3. Under Ease of Access, click Keyboard.

  4. Make sure the Filter Keys switch is set to Off.

The keys should now be more responsive.

Numeric keypad does not work

Please see the HP support document HP PCs - Numeric Keypad Does Not Work for either of the following issues:

  • The numeric keypad does not work but rest of the keyboard works correctly.

  • The numeric keypad does work but the rest of the keyboard does not work correctly.

Pressing a key once types several characters

If two or more characters appear when pressing a key, use the following steps to adjust the key repeat delay:

  1. In Windows, search keyboard and click Keyboard control panel.

  2. Drag the Repeat delay slider to Long, and then click OK to save changes.

    Figure : Changing the Character Repeat delay setting

    Keyboard Repeat delay setting
  3. If the wired keyboard is still not working, test the keyboard for key or hardware failures. You can test the keyboard for key or hardware failures using HP Hardware Diagnostic tools that come with your computer. See HP support document, HP Desktop PCs - Testing for Hardware Failures (Windows 10, 8).

       NOTE:

    During the UEFI testing you test the keyboard by pressing each key on the keyboard. The corresponding key on the screen will turn blue. If keys are pressed multiple times, the key colors cycle through blue, purple, and green to indicate the key presses. If any key that was pressed only once shows a different color than blue, this is most likely a hardware issue with the keyboard.

Computer beeps while typing

If the computer sometimes beeps while you are typing, Toggle Keys or Sticky Keys are active. The Toggle Keys can emit a beep when the Lock keys are pressed. The Sticky Keys function can emit a beep when the Ctrl, Alt, Shift, and Lock keys are pressed. Use the following steps to disable Sticky Keys and Toggle Keys:

  1. In Windows, search for and open Settings.

  2. In Settings, click Ease of Access.

  3. Under Ease of Access, click Keyboard.

  4. Make sure the Sticky Keys switch is set to Off.

    Figure : Sticky Keys setting
