    If the issue still persists, you can update the system BIOS.
    Note: Make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.

    did you tried your keyboard with other machines ? if working properly there might be a low voltage problem at your USB port.. use a powered USB hub to solve this problem..
