then press the keyboard shortcut tab .

iteachmac :

from here you can restore defaults shortcuts .

Customer :

iteachmac :

If it is not set for use in expose or spaces , please set the key for use with expose and test . you can select F5 etc in the choices for all windows ect in expose .

iteachmac :

Does they key work?

Customer :

I'm v sorry but I am not familiar with these processes. Will it be ok if I reply o your question a bit later.

setting the key for use in Expose should prove if the key is working correctly .

iteachmac :

Just open , Apple menu system preferences .

expose tab .

iteachmac :

then set your Fkey to the "all windows" option .

iteachmac :

Ok,

iteachmac :

do you have any drivers for mouse installed such as USB Overdrive

iteachmac :

USB Overdrive can affect the use of keys on the Mac .

iteachmac :

Tip: To see if USB Overdrive is installed on your computer:



  1. From the Apple menu, choose System Preferences.

  2. Look for a "USB Overdrive" icon.

iteachmac :

If you have this issue, update to a later version of USB Overdrive (http://www.usboverdrive.com/).

iteachmac :

if not disregard .

iteachmac :

You may have to find the F key setup , there may be a key that is classing with your volume control F key setting .

iteachmac :

clashing sorry.

iteachmac :

here is a guide for changing the keyboard shortcuts .

iteachmac :

you can also try fn (Function key) , hold the fn (Function key) and hit F5 .

iteachmac :

If this does not work please set the setting as before but :-

iteachmac :

Open Apple menu , System preferences . keyboard control panel .








tick / turn on , the option use F1 F2 etc as standard function keys.



iteachmac :

then hold the fn (Function key) and hit F5 .

iteachmac :

try either way F5 or hold hold the fn (Function key) and hit F5 .

iteachmac :

Does this help?

iteachmac :

Thanks.

iteachmac :

you can also try Shift and Option along with the volume key for finer volume control . normally this should work .

iteachmac :

If there is still an issue , we may have to reset the Pram .

iteachmac :

Please try resetting the SMC and Pram in turn if required it should reset the Mac hardware and then fix the issue.

-

Try this guide by following these steps :-

Reset the SMC

To reset the SMC on a Mac Book Pro ,

1 Turn off the computer and disconnect the power.

2 Remove the battery and then hold down on the power button for 5 seconds.

3 Reinstall the battery and turn the computer back on.

Test .
Pram reset if needed ..

Resetting PRAM and NVRAM

Shut down the computer.

Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously on power on.

Turn on the computer.

Press and hold the Command-Option-P-R keys.
You must press this key combination before the gray screen appears.
You must use the build in keyboard or a usb keyboard for imacs and Mac pros or if a laptop keyboard is not working correctly etc.

Hold the keys down until the computer restarts and you hear the startup sound for the second time.

Release the keys.

Your computer's PRAM and the NVRAM are reset to the default values.
The clock settings may be reset to a default date on some models.
Set the clock using the internet via the Time and date preferences , Apple menu , System preferences , Time and date control panel .

If the Time and date is not held in the Mac correctly it will lose time once powered down and no AC or battery is attached for more than 20mins .
If so the internal battery may have to be changed for new .

Let hope this fixes the Mac , please let me know if this helps .

Thanks .

Customer :

Hello - tried all your suggestions. No evidence that F5 button works at all. Does this mean a hardware fault with the button?

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
