This problem is likely to be a lost connection. The connection between the mouse and the USB receiver or the keyboard and the USB receiver can be lost due to several reasons such as:

• Low batteries
• 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 USB receiver must be plugged directly into your computer)
• Using your cordless mouse/keyboard 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 devices.
