Function Key "Fn"

Solved/Closed
I installed a Logitech MX 700 wireless keyboard and mouse.
Since then, if I want to use the laptop's keyboard, I have to press the "Fn" key to access the normal keys on the keyboard. How can I disable "Fn"?
I have uninstalled all Logitech drivers, but nothing changes.
Help, help.

Thank you for your responses.
