HP 250 G1 - function keys

Hello.

I have HP 250 G1 with Windows 7 and drivers installed (no unknown devices in Control Panel) and in general everything works fine except that function keys (F1, F2 etc.) don't work right away.

I need to press FN first and then function keys work normally. Otherwise function kesy have multimedia assignment.

Is it correct?

For me the sequence is switched. F1, F2 should work as default and then FN + F1, F2 should return multimedia functions.

Can you guide me on that matter?
