Every time i press F3/F4 it will adjust screen brightness and I have to hold down the FN key to use >any of the F functions normally. I cannot seem to turn this off.
Usage of FN keys can be described as FN+Fx. With other words when you want to use one Fx key you MUST hold down FN key to activate flash cards so your question is not understandable for me.
I don’t understand what do you want to “turn off”.
