Mouse is not 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 batteries 
• Moving the receiver from one USB port to another.
• Moving the USB 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 M185:

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 360023403293 

4. Turn on your mouse.

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
