Mouse isn't working

If your mouse isn't working, the problem is likely a lost connection. The connection between the mouse and the USB 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 wireless 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 MK215 mouse

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

2. Make sure you have fresh batteries in your mouse. For instructions on changing your mouse batteries, see answer 360023420193.

3. Plug the USB receiver securely into a working USB port on your computer.

4. Turn on your computer.

Reconnecting your mouse

1. Download and run the Logitech Connection Utility software from the MK215 Downloads page.

2. On the Logitech Connection Utility Software Welcom screen, click Next to continue.

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

   NOTE: The mouse doesn't have an on/off switch. To turn the mouse off and on, remove and re-insert the batteries.

   

4. When your mouse is detected, you'll see a confirmation message. Click Yes and then Next.

   

5. Click Finish to exit the Logitech Connection Utility software. Your mouse should now be connected.

If this solution doesn't work after a couple of attempts, restart your computer and try the reconnection process again.

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