Set F-Keys primary instead of special keys on Lenovo

If you press FN + Esc it switches between the 2 modes. Visible with the led on the FN key.

It is easier to use F1, F2 etc; when you want to use the special functions you can just use the FN key plus the F keys.

The answer saying to use Fn+Esc didn't work for me. I'm using a Lenovo G50.

What did work was to shut down, press the tiny button next to the power socket using the end of a pen, go to the BIOS settings, and change the hotkey setting.

Now I have to hold Fn to access the media functions, and if I don't I get regular function key behaviour.

in case you swapped CTRL with FN keys in BIOS, it is:

CTRL + ESC

LED on FN key will still indicate the status
