Brightness/audio keys require function keys

[Craigrox]

Hi everyone,

I've freshly installed OS X Yosemite over my trusty ProBook 4340s using the Clover method, and I'm finding that to change the brightness or audio volume for the first two minutes after boot I can just use the actual key (F2, F3 etc.) without the use of Fn. However after then I need to use the Fn key + F2 to turn the brightness down for example.

Is anyone else experiencing this or know how to modify this behaviour?

Cheers!
Craig

No.

Do a fresh install to see if you can reproduce the problem. It is likely a 3rd party software you have installed.

Unfortunately at the time of posting this was a completely fresh install, with no 3rd party applications installed. I will try a fresh install however and get back when I can


Edit: Unchecked the top option and now it works..

Was having the same problem, but like you was able to toggle the described setting in system preferences. Does it stay this way for you and save the change? I find I have to go back in on start up and sometimes after sleep and turn it off again.

I have the same problem too, and whenever I start the Mac OS X, it either be fn+function or function only
I do the same in the preferences, but I still have the same problem sometimes it is fn+function and sometimes function only !!
