This problem is likely to be a lost connection. The connection between the mouse and the USB receiver can be lost due to several reasons such as:
- Low battery
- Moving the USB receiver from one USB port to another
- Moving the USB receiver to another computer
- Plugging the USB receiver into a USB hub or other unsupported device such as a KVM switch (your Unifying USB receiver must be plugged directly into your computer)
- Using your cordless mouse on metal surfaces
- Radio frequency (RF) interference of more powerful wireless devices such as:
- Wireless speakers
- Computer power supplies
- Monitors
- Cellular telephones
- Garage door openers
Eliminate any problem sources mentioned above that might be affecting your device.
