HP Pavilion Wired Keyboard 300 - "Fn" key is switchen on by default

[Apoul]

I have purchased a number of HP Pavilion Wired Keyboard 300 and tried them on various computers.
It has not been possible to turn off the Fn key function, I have tried FN + ESC, FN + Caps Lock but none of these key combinations work.
Is there any software that can permanently turn off the FN keys?

The Fn function key setting of the machine itself can refer to: Restart the computer, click F10 to enter bios continuously, and then use the left and right keys of the keyboard to move to the system configuration----find the action key mode is enable by default. At this time, you can directly use the F1-F12 function keys without using FN. But it is not sure whether it is useful for an external keyboard.

There is no setting in BIOS for this, since the keyboards are external USB-keyboards (we have looked in BIOS - as well).

Lenovo has the same issue for their Lenovo Slim Keyboards - therefore they have published a piece of software to invert the Fn-key-function.

That works perfectly.

But of course that software doesn't work for our HP keyboards.

Doesn't HP have a piece of software, that does the same?
