Many laptops let you decide which set will work without the Fn key. For example, my current Lenovo shipped set up so that the F keys would by default do the laptop specific things (as yours seems to be), and one needed to hold the Fn key to get the regular functions. I switched this so that the F keys, without the Fn key, work as they would on any computer.
