K780 Multi-Device Wireless Keyboard  Y-R0061

K780 keyboard does not work or loses connection frequently

Updated:  06/29/2016 05:35 PM

Keyboard isn't working
In order for your keyboard to work with your device, the device must have built-in Bluetooth capability or be using a third-party Bluetooth receiver or dongle. 
NOTE: The K780 keyboard isn't compatible with a Logitech Unifying receiver, which uses Logitech Unifying wireless technology.

If your system is Bluetooth-capable and the keyboard isn't working, the problem is likely a lost connection. The connection between the K780 keyboard and the computer or tablet can be lost for several reasons, such as:
  • Low battery power
  • Using your wireless keyboard on metal surfaces
  • Radio frequency (RF) interference from other wireless devices, such as: 
    • Wireless speakers 
    • Computer power supplies 
    • Monitors 
    • Cell phones 
    • Garage door openers
Try to rule out these and other possible problem sources that might be affecting your keyboard.

Keyboard frequently loses connection
If your keyboard frequently stops working and you keep having to reconnect it, try these suggestions:
  • Keep other electrical devices at least 8 inches (20 cm) away from the keyboard
  • Move the keyboard closer to the computer or tablet
Before reconnecting your keyboard
Before you try to connect your keyboard again:
  1. Check the battery power by turning the keyboard off and then back on again using the ON/OFF switch on the bottom of the keyboard. Notice the LED indicator color to the left of the ON/OFF switch. If the LED indicator is red, the batteries need to be replaced.
  2. Try using the Windows key or type something to verify it's working.
  3. If it's still not working, follow the link below to reconnect your keyboard.
Reconnect your keyboard
To reconnect your keyboard, please follow the steps for your specific operating system in Connect your Logitech Bluetooth device.
