Shortcut Keys do not work (Volume, Brightness etc.)

'Screen and keyboard brightness and Volume keys' don't work:

MacBook Pro Late 2010 15"

OsX 10.8.2

Problem first noticed about a week ago after uninstalling LogMeIn.

Uninstalled LogMeIn and now the Screen and keyboard brightness and Volume keys don't respond.

Troubleshooting that I have done:

1) restart computer- Failed- many times now and still not working.

2) reset PRAM - Failed

3) Reset SMC - Failed

4) Tested keys while in bootcamp (win 7)- Success- so I figure it is not a hardware problem

5) tested keys in second mac user - Failed

6) insured all files from LogMeIn are gone- Failed (I think I have removed them all now, but still no go)

7) Tested Fn related functionality of Fn Keys - All work fine (when holding the Fn key), but just not the Mac related fun (with or without the Fn Key)

I am stumped. the keys clearly work, but for somereason the shortcuts to them have been deactivated or removed.

Any help would be greatly appreciated.

I ended up formatting and reinstalling everything. It was the only fix I found.

bar going to the extent that bhhclarke went to and formatting everything, does anyone else have a suggestion?

Apple?

PS, thanks bhhclarke. I appreciate you taking the time to respond. I hope that isn't the only solution.

I'm having the same issue. if I restart the mac it helps but once i close the laptop lid and log back in the volume and brightness buttons wont work. but the F12 and other buttons do actually work. The shortcut keys also get reset everytime I log in. I can not format the machine. I develop on it an the hassel of that while I have so much work to do is un thinkable. Can't believe Apple haven't release or adviced on a proper solution! I found my retina macbook pro more buggy then my old 2008 mac model and that's running the same software and os..

Hello,

Has anyone solved the loss of volume, backlight, screen brightness buttons yet. Given that LogMeIn are now charging for the earlier free service I suspect we will see many more people uninstalling the LogMeIn client...

Hey Allan,

I tried every method I found, but nothing resolved it without restoring.

As such in the end I booted into the recovery partition and followed the options to restore from my Time Machine backup. Please be sure to backup before doing this. All data on your computer will be lost, and replaced with your Time Machine data.

Hi Nobelton,

Many thanks for the reply, it looks like I will need to bite the bullet and reboot.

Thanks

Alan

Hi,

Managed to rebuild from complete re-install of OS X, not an experience I want to repeat in a hurry!

Allan

Ha! I hear you. Ya it can get quite time consuming and confusing.

Glad it worked out though.

Hi! My shortcut keys - volume, brightness, etc - stopped working last night, but today I solved the problem. Check the System Preferences->Keyboard. In the Keyboard tab, make sure that "Use all F1, F2, etc.keys as standard functions" is unchecked. Hope this solves your problem too!

Fixed it : But there is still the issue of how all this happened to so many around the globe ? Sound , brightness , and other issues I fixed before this that shouldn't have been able to be altered remotly or unlocked ///????? The Bigger Question.

thanks i live in guatemala a had the same problem and i try all the solutions before describe for all the guy but only your solution and the most funny i was the most simple thank again pd sorry im still learning grammar

This is the first post that addresses my problem but I did not know, until now, it was related to deleting LogMeIn. this makes sense since I recently removed that App from my MacBook Pro. I lost my volume, keyboard brightness and screen brightness.

I don't see any fix for this in any of the posts that I did not already tried, short of re-installing Mac OS.
