MK270 mouse is not working or frequently loses connection

Troubleshooting steps if your MK270 mouse is either not working or loses connection frequently

Mouse isn't working

When your mouse isn't working, the problem is likely a lost connection. The connection between the mouse and the Unifying receiver can be lost for several reasons, such as:

  • Low battery levels

  • Moving the USB receiver from one port to another

  • Moving the USB receiver to another computer

  • Plugging the USB receiver into a USB hub or other unsupported device such as a KVM switch ( NOTE:  Your USB receiver must be plugged directly into your computer)

  • Using your wireless mouse on metal surfaces

  • Radio frequency (RF) interference from other sources, such as:

    • Wireless speakers

    • Computer power supplies

    • Monitors

    • Cell phones

    • Garage door openers

 

Before reconnecting your mouse:

  1. Fix or rule out the potential problems listed above.

  2. Turn your computer on.

  3. Insert fresh batteries in your mouse. For instructions on changing your mouse battery, see answer 1500002195561.

  4. Turn on your mouse. The power indicator on top should be green.

    If the power indicator is not illuminated, move the power switch on the bottom of the mouse to the "ON" position. The power indicator should now turn green.

  5. Make sure the receiver is securely plugged directly into a working USB port on your computer.

 

Reconnecting your mouse

  1. Download the correct version of Logitech SetPoint Mouse and Keyboard Software from the MK270 Downloads Page.

  2. Launch the Logitech Unifying Software:

    Windows: Start > Programs > Logitech > Unifying > Logitech Unifying Software

  3. Click Next at the bottom of the Welcome screen.

  4. Follow the on-screen instructions to turn your mouse off and then back on.

  5. When your mouse is detected, you'll see this window:

    NOTE:  The M185 mouse is included in the Wireless Combo MK270.

    If you can use the mouse, select Yes and then click Next. Otherwise, repeat from step #4.

  6. Click Finish to exit the Logitech Unifying Software. Your mouse should now be connected.

Mouse frequently stops working

If your mouse frequently stops working and you keep having to reconnect it with the USB receiver, try these suggestions:

  • Keep other electrical devices at least 8 inches (20 cm) away from the USB receiver

  • Move the mouse closer to the USB receiver

  • Move the receiver to a different USB port on your computer
