IdeaPad G/Z/P: Keyboard Fn + F1-F12 swap


How can I swap the F1-F12 button functionality with the Fn functions? I do not want to press Fn+[mute volume] everytime I want to hit F1 etc. I read somewhere that there is an option which changes this in BIOS, however, that applies only for other Lenovo series and not mine G510.

It is really tough for me as I'd like to have my keyboard to function like a conventional key with out have to hit FN all the time. In some instances If I'm playing a game and require to use the F4 key, my system closes the application as it detects it as a close funtion key.


This specific issue is limited to some models of G/Z/P series of unable to achieve the traditional function by pressing F1 to F12 directly. 


Should your machine falls under the caterogy of G, Z or P series, a BIOS update is required to address this issue.

I have the same problem, i used the bios update but i can only "enable" and "disable" the fn keys. There is no option to swap the F1-F12 keys with the FN keys. Anyone knows a solution for that?
