Keyboard Usage and Troubleshooting Guide



When your Wired USB, Wireless USB or Bluetooth® keyboard is not working as it should, refer to the expanding section below that best matches the issue you are having and follow the instructions.

Suggested Quick Fixes:

  1. Reseat the USB cable or wireless USB receiver.
  2. When you have a wireless USB or Bluetooth mouse, install new batteries.
  3. Save any data, close any open program(s) and restart the computer.

Select the tab below that matches the type of keyboard you have. Follow the steps on how to connect your keyboard to your computer.

  1. Locate the wireless USB receiver that came with your keyboard.
    Note:

    When buying a keyboard or mouse with a computer:

    • Look in every compartment of the box that the device(s) came in. The wireless USB receiver is small and can be easily over looked. The receiver will have a informational tag attached to help you locate the receiver. Refer to Figure 1 to see the size and shape of the receiver.

    When buying a keyboard or mouse separately from a computer:

    • The wireless USB receiver will be under the keyboard when buying a keyboard or keyboard, mouse combination, and under the mouse when bought separately. The receiver will have a informational tag attached to help you locate the receiver. Refer to Figure 2 for the typical location, size and shape of the receiver.
    Wireless USB Receiver
    Figure 1: Wireless Receive
    Wireless USB Receiver
    Figure 2: Wireless Receiver Location in Packaging

    When you cannot locate your wireless receiver after you have unpacked the devices, some mice and keyboards have a place to store the wireless receiver. Look under the mouse buttons where the batteries are or in the battery compartment on a keyboard, but they are not shipped in those locations.



  2. Insert the wireless USB receiver as shown in Figure 3.

    Wireless USB Receiver Placement
    Figure 3: Wireless USB Receiver Insertion
    Notes:
    1. The receiver only goes in one way. When the connector does not seem to fit, adjust the angle or flip it over.
    2. The receiver that came with the keyboard does not need to be configured.

    3. Your receiver and keyboard may have a connect button; if so, press the connect button on the receiver and on the bottom of the keyboard. See the example in Figure 4.

      Figure 4: Wireless Keyboard Connect Button Location

  1. Look at the connector on the end of the USB keyboard cable.

  2. Look for a matching port and USB symbol on the notebook. For more information, refer to Figure 1.


    Figure 1: USB Port Locations
    Note: The connector only goes in one way. When the connector does not seem to fit, adjust the angle or flip it over.

For information on how to connect to your Bluetooth keyboard, refer to Dell Knowledge Base article Fix, Connect to and Learn About Bluetooth.

    • Speakers.
    • Printers.
    • Scanners.
    • USB devices.
    • USB flash drive or other external storage devices.
    • External monitor.
    • External keyboard.
    • External mouse.

      When your computer is attached to a docking station, undock it.



  4. Turn the computer back on and retest the keyboard. When the keyboard does work correctly, attach one external device at a time and test the keyboard to see which one may have caused the issue.


  5. Make sure the BIOS is updated to the latest version. For more information, refer to Dell Knowledge base article What is BIOS and How to Download and Install the latest BIOS?


  6. When the keyboard still only works intermittently, refer to the instructions below that best matches the issue you are having:
    1. When a specific key is not working or sticks, turn off the computer and use a can of compressed air to clean around the problem key and then retest the keyboard. For more information, refer to the How to Clean Your Keyboard section.
    2. When the issue only occurs in a specific application program, test the keyboard in another application program, such as Notepad. If the problem only occurs in a specific program, you need to troubleshoot that specific program.
    3. When you have software that may change how the keyboard operates, uninstall or disable it, including:
      • Keyboard macro programs.
      • External gaming keyboard software or drivers.
      • KVM (keyboard, video, mouse) switch software.


  7. Try an external wired USB, wireless USB or Bluetooth keyboard when available, to test if it responds correctly.


  8. When the Keyboard still does not work after following the preceding steps, refer to Dell Knowledge Base article Resolve Hardware Issues Using ePSA or PSA Diagnostics and Guide to Error Codes.
    Notes:
    • The test will determine if the keyboard is detected at a hardware level below the Operating System (OS). When it is detected, it means the OS or installed software is preventing the touchpad from working. You can use a restore point to return the OS to a previous state when the keyboard worked (in Windows 10 it is called refreshing the OS). If that does not work you may need to reinstall your OS. For more information, refer to Dell Knowledge Base article How To Restore or Reinstall Microsoft Windows on a Dell Computer.
    • When an error is reported during the test, write down the error and the validation code as seen. Then on another internet device, browse to the SupportAssist Pre-Boot System Performance Check page to submit the issue.

  1. Reseat the USB cable into the computer.


  2. Make sure the Number Lock Key is set correctly.
    Note: The numeric keypad on a desktop keyboard is normally turned on. When it is off, no numbers appear when the keys are pressed. Press the Number Lock Key to toggle the numeric keypad on and off.

    For more information on where the Number Lock Key is, refer to the document that came with the keyboard or browse to the Keyboard and Mouse Manual page for the manual.



  3. Turn off the computer.


  4. Unplug any non-essential external devices, including the following:
    • Speakers.
    • Printers.
    • Scanners.
    • USB devices.
    • USB flash drive or other external storage devices.


  5. Make sure the BIOS is updated to the latest version. For more information, refer to Dell Knowledge base article What is BIOS and How to Download and Install the latest BIOS?

    Notes:
    • Look for the Backlit key first on the Function key row across the top of the keyboard, otherwise it may be in the lower-left side of the keyboard.
    • When your computer does not have the Backlit key, your computer does not have this feature.
    • For more information refer to Dell Knowledge Base article How to Troubleshoot the Backlit Keyboard on Your Dell Notebook Computer.
  1. Make sure the computer is turned off.

  2. When using a wired, wireless or Bluetooth keyboard turn the keyboard upside down and shake it gently to remove any loose material.


  3. Use a vacuum cleaner specifically designed for computers, when available.


  4. Use a can of compressed air to remove any additional loose material, when available.
    Caution: Do not turn the can on its side or upside down. This causes a very cold liquid to spray out and can damage your keyboard and skin.


  5. Using a Microfiber or terry cloth wipe the keys and frame around the keys.
    Note: When there is build up, take a cotton swab, microfiber towel or terry cloth and dip it in isopropyl alcohol. It should be damp but not wet. Wipe away the buildup and let the isopropyl alcohol evaporate away before using the keyboard again.

When a keycap comes off, perform the following steps to try to put the keycap back on the notebook:

  1. Make sure the area that was under the keycap is clean. Using a can of compressed air is best.
    Caution: Do not turn the can on its side or upside down. This causes a very cold liquid to spray out and can damage your keyboard and skin.


  2. Examine the plastic scissor spring that was under the keycap for any damage as indicated by the red circles in Figure 1.
    Key Scissors Structure
    Figure 1: Scissor Spring Mechanism on a Notebook Internal Keyboard
    • When the plastic scissor spring looks intact, align the keycap and gently press down to try to reseat the keycap.
      Caution:: Do not try to force the keycap back on, as you may damage other parts of the computer.
    • When there is damage to the plastic scissor spring, the keycap cannot go back onto the keyboard.
