Mouse isn't working

If your M187 mouse isn't working, the problem is likely a lost connection. The connection between the mouse and the 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 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 connecting 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 360023409073.

4. Turn on your mouse.

   

Reconnecting your mouse

1. Download the correct version of Logitech SetPoint Mouse and Keyboard Software from the M187 Downloads page.

2. Press the Windows key + R to Run.

3. Type C:\Program Files\Logitech\SetPointP\ConnectUtility.exe and press Enter.

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

   

5. When your mouse is detected, you'll see a confirmation message. 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.

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

Mouse frequently stops working

If your mouse frequently stops working and you keep having to reconnect it with the Unifying 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
