Mouse isn't working
If your M705 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 USB one 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
