How to Connect a Wired, Wireless or Bluetooth Mouse to Your Computer

 

  1. Locate the wireless USB receiver that came with your mouse.
    NOTE:

    When buying a keyboard or mouse with a computer:

    • Look in every compartment of the box that the devices came in. The wireless USB receiver is small and can be overlooked. The receiver has an informational tag that is attached to help you locate the receiver. See 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 is under the keyboard when buying a keyboard or keyboard mouse combination, and under the mouse when bought separately. The receiver has an informational tag that is attached to help you locate the receiver. See Figure 2 for the typical location, size, and shape of the receiver.
    Wireless USB Receiver
    Figure 1: Wireless Receiver    		   Wireless USB Receiver
    Figure 2: Wireless Receiver Location in Packaging

     

    When you cannot locate your wireless receiver after you have unpacked the devices, some mouses 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.

    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. When using the receiver that came with the mouse, no configuration is needed.

 

NOTE: The connector only goes in one way. When the connector does not seem to fit, adjust the angle, or flip it over.
  1. Check the connector at the end of the USB mouse cable to determine the type of connector your keyboard or mouse has. For more information, see the figure below:
    PS/2 USB
    Connector USB Connector
  2. Find the port and USB symbols on your laptop:
    • Laptop：
      Notebook_USB
    • Desktop：
      PS 2 ports

To Pair or Re-pair the Bluetooth mouse to the computer, see the Dell Knowledge Base article Bluetooth Troubleshooting and Usage Guide.

Resolving Cursor and Scroll Wheel Issues

 

NOTE: The following steps apply to all brands of wired USB mouses.
  1. Reseat the wired USB mouse cable into the USB port.
  2. Ensure the optical opening on the bottom of the mouse and around the scroll wheel is clean. For more information, see the How to Clean Your Mouse section.
  3. Ensure the surface that you are using has enough of a pattern in it that the mouse can tell when it has been moved (a mouse pad is best, since the mouse judges movement by reflections, a uniform surface is harder for the mouse to tell when it has been moved).
  4. Try the wired USB mouse in another USB port on the computer. A notice that drivers are being installed may appear; if so, wait until a message that the drivers were installed before you use the mouse.
  5. Try another wired USB mouse, when available. A notice that drivers are being installed may appear, if so, wait until a message that the drivers were installed before you use the mouse.
  6. Try your wired or wireless mouse on another computer, when available. A notice that drivers are being installed may appear, if so, wait until a message that the drivers were installed before you use the mouse.
  7. Save any data, close any open programs, and restart the computer. When you do not have another mouse or touch screen, you may have to press and hold the power button down for at least 15 seconds to turn the computer off, and you lose any data that is not saved.
  8. Using the SupportAssist application provides automatic computer updates and detects issues that are resolved for you. Let us take the effort out of maintaining your Dell Computer or Tablet. For more information about SupportAssist, browse to the SupportAssist for PCs and tablets
  9. When the mouse still does not work after following the preceding steps, see the Dell Knowledge Base article Resolve Hardware Issues With Integrated and Online Diagnostics (SupportAssist ePSA, ePSA, or PSA Error Codes).
    NOTE:
    • The test determines if a wired USB mouse is detected at a hardware level below the Operating System. When it is detected, it means that the operating system or installed software is preventing the wired USB mouse from working. You can use a restore point to return the operating system to a previous state when the mouse worked (in Windows 10, it is called refreshing the operating system). If that does not work, you must reinstall your operating system. For more information, see Dell Knowledge Base article Factory reset, 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 Enhanced Preboot System Assessment page to submit the issue.

 

  1. Ensure to use the wireless USB receiver that came with your wireless mouse. Using another receiver may mean it uses another technology, and is not compatible with the mouse.
