If your keyboard is not working or frequently loses connection try the following steps:
1. Check the batteries or make sure your device is charged.
2. Make sure the keyboard is On.
3. Keep other electrical wireless devices away from the USB receiver to avoid interferences.
4. Move the keyboard closer to the USB receiver.
5. Unpair/repair or disconnect/reconnect hardware:
o If you have a Unifying receiver, identified by this logo, see Unpair a mouse
or keyboard from the Unifying receiver for instructions.
o If your receiver is non-Unifying, it cannot be unpaired. However, if you have a
replacement receiver, you can use the Connection Utility software to perform the
pairing.
6. Try a different USB port. If using a different USB port works, try updating the
motherboard USB chipset driver.
7. Windows only — check USB port power settings.
8. Upgrade the firmware for your device if available.
9. Try the device on a different computer.
