If you encountering your keyboard lights start flicking or is making high pitch sound, it is usually the keyboard has insufficient power to drive the light.

While Tesoro Keyboard is using a single USB connection from your system, it is limited to 500mA which the keyboard can use. If any situation that keyboard is drawing less than 500mA while your keyboard is fully illuminated, lights will start flicking, making high pitch sound, or some lights will not even working from your keyboard.

 

  • Please try with a different USB 2.0 port from your system
  • Check your cable has a good connection or try with a different USB cable.
  • Use USB 2.0 port instead of USB 3.0 port on your system.
  • Connect the keyboard to your computer USB port 2.0 directly. Do not use any USB hub.
