For some reason, my Fn key appears to be activated all the time. Every time I click on any of the Fx keys (F1, F2, F3…) it doesn’t perform the normal tasks, but it performs as if I have pressed Fn + F1. Looking at lights at the lights at the bottom right of the keyboard (at the right of the touch pad), there are a couple of lights. The light on the right is all the time switched on, and I suspect it indicates the Fn key is activated.
How can I deactivate it please?
