Hardware keyboard controls not working

[HodgeHi]

I hope someone can help.

I have had this problem for a while now. When i need to either turn the sound down, up or mute, reduce or increase brightness or use the num lock i cannot as it does not respond. i have tried to turn on or off the option for using the fn key to provoke the os into making it work???

I have re-installed the base os after erasing hdd (with 0ne zero pass) before installing, but just the same. I upgraded to 10.4.6 to install the keyboard update but no difference.

i have now run out of options. I have upgraded right up to date and still nothing. I hhave installed alll firmware and smc updates but still nada. I tried to reset the nvram but could not get it the beep twice instead it just restarted.

anyone know how i can resolve this issue. Its been going on for about 4-5 months now.

The machine? Macbook pro 2.ghz with 2GB ram.

Sorry i'm a bit confused by your answer. Did you mean system prefs when you pointed out control panel as i am using os x tiger. I forgot to mention this and it is in tiger where the problem is not parallels, but that does give me an idea of checking whether it works in Windows...

thanks

Hi

Check NumLock.
Check the Settings in System Preferences > Keyboard and Mouse.
The System keyboard function is disabled if the Use F1-F12 ... box is ticked.
In the keyboard Shortcuts pane check which shortcuts are actually configured.
Quit System Preferences.
Delete ~/Library/Preferences/com.apple.systempreferences.plist
Log out and login again.

Hello, Thanks for the response.

However i have checked, checked and checked agin the settings that you suggested above but still no go. I took my macbook pro into the Store and told them my problems. excellent service. They booked it in for repairs to replace the keyboard, display and charger and replaced them in 2 days.

Pretty good i say, considering they had to order the parts in as well.
