Mouse isn't working

If your M510 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 receiver from one USB port to another
  • Moving the receiver to another computer
  • Plugging the receiver into a USB hub or other unsupported device such as a KVM switch (NOTE: Your Unifying receiver must be plugged directly into your computer.)
  • Using your cordless mouse on metal surfaces
  • Radio frequency (RF) interference from more powerful devices such as:
    • Wireless speakers
    • Computer power supplies
    • Monitors
    • Cell phones
    • Garage door openers

Before reconnecting your mouse

  1. Fix or rule out the potential problem sources listed above.

  2. Turn your computer on.

  3. Insert fresh batteries in your mouse. For instructions on changing your mouse battery, see answer 17990.

  4. Plug your receiver directly and securely into a working USB port on your computer.

  5. Turn on your mouse.

Reconnecting your mouse

  1. Download and install the latest software from the M510 Downloads page.
