Hi Everyone

I'll apologise now if I can't even explain this right but I'll give it a go.

I just had my new ASUS GL551 arrive today and whilst setting up, upgraded from the Windows 8.1 it came with to Windows 10.

All of my functions keys are working besides the Keyboard backlight, this was working prior to the Windows 10 upgrade but now appear to have suddenly stopped working. The keyboard lights up when the machine is booted up but the FN + F3,F4 do not work.

I don't even know if you can turn these off? If so, how? Sorry, I'm a total newbie when it comes to this I've probably done something stupid and turned them off.

Can anyone help please? I'm worried that I've upgraded to Windows 10 and now the Keyboard backlight won't work and I'm stuck with it in the dark!

Thank you in advance.
