Macbook Pro 15inch Volume, brightness keys not working (All the special F keys)

Hello,

I have this problem on my MBP where my Fn (Function Keys) on the top row of my keyboard don't work properly. I use these keys all the time to adjust brightness, keyboard LED brightness, pause, play and volume but they aren't working anymore. When I press F12 it shows the dashboard. I already have the 'Use all F1, F2 ect. keys as standard function keys' unchecked in System preferences, Keyboard. I am on a bootcamped MBP but mainly use the Mac OSX. This problem is occuring on Mac OSX not Windows. I have not dropped my MBP to damage it or anything like that. I have installed 16GB Ram and the Seagate Momentus 750GB Hybrid SSD a few months ago. Anyone know how I can fix this?

Any help will be extremly appreciated!

Check the setting in Keyboard, Keyboard Tab, that the "Use all F1, F2, ect. keys as standard function keys" isn't checked.

I had the same problem and fixed it by doing the NVRAM reset:

I got this info from the answer to another question:

Try a SMC reset:

You can try a safe mode boot, sometmes it will fix glitchy things:

Power holding the shift key, continue to hod the shift key till you see the progress BAR then release and allow to finish booting (note this will take longer than usual, as will the shut down)

After it boots it should say safe mode in red on the screen, log in, log out and shut down. Restart normally.

All the best
