hp probook 430 g5 can't disable/enable fn+fn keys

[xuta]

I have a hp probook 430 g5 and i would like to acess the function keys F1 to F12 without pressiong "Fn" key to do what they have to do "Help","search","refresh", googling and in the hp help i found that there is an entry in the boot menu where i can enable or disable (switch) the need of press "Fn" to have a "classic" behaviour. The curious thing is that whatever is the option i select on the boot menu, the behaviour of the Function keys won't change. Always I have to press Fn+the function key to meke them work as "classic behaviour".

I would apreciate if anyone may help, becouse is a very anoying thing that every time I press the F3 key the volum gets louder but no search is opened....
