If you're having trouble getting the backlight to work on your Logitech K740 Illuminated Keyboard, there are a few things you can try. First, make sure you have plugged the USB cable directly into your computer or a powered USB hub. Due to the high-powered nature of the backlight feature, the keyboard may not work if plugged into an unpowered USB hub or other devices.
If you have already plugged the keyboard directly into your computer or a powered USB hub and the backlight still doesn't turn on, try plugging the USB cable into a different USB port on your computer. Sometimes, certain USB ports may not provide enough power for the keyboard to function properly.
Additionally, ensure that you have installed the Logitech software to enable enhanced features, including the backlight control. You can download the latest software from the Logitech website at www.logitech.com/support/k740.
If you have followed these steps and are still experiencing issues with the backlight, it may be helpful to consult the Logitech support team. You can find the contact information for your region on the Logitech website or refer to the numbers provided in the manual.
Remember, the Logitech K740 Illuminated Keyboard has four steps of light intensity, and each press of the backlight control key provides another step. So, once the backlight is working, you can adjust the intensity to your preference.
For further assistance or troubleshooting, please refer to the Logitech K740 Illuminated Keyboard instruction manual.
