Why is my K980 not charging?

If your Logitech K980 keyboard isn't charging, the most likely cause is a blocked or obstructed solar bar.

The K980 keyboard features a built-in solar cell, often referred to as the solar bar, which converts both indoor and outdoor light into power. For the keyboard to charge properly and maintain its battery life, this solar bar needs to be exposed to light.

Placing objects on top of the solar bar, even small ones, can significantly reduce its ability to harvest light energy. This can lead to the battery draining over time, as the keyboard uses more power than it can generate.
