Suddenly all my F keys have flipped.
They work as if Fn key pressed, and when Fn key pressed the non-Fn function happens.
The F keys do the opposite.
So the volume control works without me pressing the Fn key, which it should not do
Is this a hardware problem? I tried a clean install twice, but no luck.
What is the model number of your system?
