Possible solutions
1 Check the battery level.
• If the wireless mouse/wireless keyboard uses a rechargeable
battery, ensure that the battery is fully charged.
• If the battery is exhausted, replace it with a new one.
2 Turn the wireless mouse/wireless keyboard off, and then turn
it on again. Check if the battery-status light is flashing amber,
indicating that the battery power is low. If the battery is fully
depleted, the battery-status light will not turn on.
3 Restart your computer.
1 Ensure that the USB receiver is connected directly to your
computer. Avoid using the port replicators, USB hubs, and so on.
2 Change the USB port. Insert the USB receiver into another USB
port on your computer.
