Why sometimes all the Function keys don't work?

It always happens in a sudden, randomly.
keys like F8-12 sometimes just don't function like wt they're supposed to do. But it'd be fine if I simply restart the system.
does anyone have idea wt's wrong with it?
p.s. i'm using 10.6.3 with Macbook white (mid'07)

I agree with Akuma.
The Toshiba VAP provides a lot of features and they are required for other Toshiba utilities.
On my Satellite notebook I have VAP installed and FN keys are working.
Try it with the newest version that you can find on the Toshiba website:

I have a macbook pro with OSX Mavericks 10.9.5 and some keys that are not working. Specifically, the enter/return button, the "p", "0", ";", and all the function keys. What's really weird is that happens randomly. I've never spilled anything on it

I have a macbook pro with OSX Mavericks 10.9.5 and some keys randomly are not working. Specifically, the enter/return button, the "p", "0", ";", and all the function keys. What's really weird is that happens randomly. I've never spilled anything on it, and I can't for the life of me figure out how to fix this. Can anyone help? of course this happened after my warranty expired.

**update**
I don't know if this will help someone but I am posting this for that purpose. In the past when I first had this problem, I'd read a post somewhere (sorry, long ago, don't have the link) where an individual was having the same problem and they stated that when the MBP got heated, that's when the keys would stop working, and they went into the MBP and jiggle some stuff around (a specific wire, I'm not electronically inclined so I know NOT of what they spake!). Well I didn't want to do that but it always stuck in the back of my mind. I had given up, really, and was planning to take my MBP to the apple store. But by chance one night I left my MBP on the floor where it's cool, and when I turned it on, the problem went - poof! It seems there was some validity to the post that spoke about heat, because my problems started when I would stream foreign dramas on my MBP for hours at night, and I would hear the fan going off all the time, and in the mornings, my "p", "enter", "0", ";", and all the function keys would stop working.
So, maybe try keeping the MBP in a cool place when it's off. Since I've started doing this overnight every night (keeping it on the cool floor, out of reach of any big feet), I have not had a single problem with my keyboard.
Hopefully this might help someone.

Some function keys don't work onSatellite P850-138

Hi,
I've got a Satellite P850-138 and the standard functions on the function keys don't seem to work (NOT the F1-F12 that you have to use Fn for, they work fine).
The video functions on F6-F10 seem to work fine when playing a video. The functions on F2-F4 and F11-F12 don't seem to work at all. (brightness up/down, switch screen, enable/disabled touchpad, volume and wireless)
Any advice on how to get them working?
Thanks in advance.

The first thing you can try is to reinstall Toshiba value added package.
Remove preinstalled version, restart the notebook and install latest version from Toshiba download page.

What can I do if my function keys don't work correctly?

QuestionWhat can I do if my function keys don't work correctly?
AnswerFunction keys can mean a few different things. You might be having a problem with the F-keys near the top of your keyboard (F1, F2, etc.), the secondary functions of the F-keys (toggling the wireless or touchpad, for example), or special media keys on your laptop.
There are a few steps you can take to try to resolve these issues. Try the suggestions listed below in the order presented. If a step fixes the problem, you're done! If a step doesn't fix your problem, continue to the next step.
Understand the FN key
First, ensure you understand how to use the FN key. In most newer models, the special utilities of the F-keys are used when you press the F-keys. To use the F-keys, you need to hold FN first. In older models, this was reversed. pressing the F-keys activated the F-keys. The special utilities of the F-keys are used while holding FN. If you're having trouble using your F-keys, try both with and without the FN key.
Reinstall TVAP or Toshiba Flash Cards Utility
Some models may use the Toshiba Value Added Package or the Toshiba Flash Cards Utility. Check the support site to see if these utilities are available for your model. If you see either listed, download and install it. Some models don't use these utilities; it's okay if you don't see either of them.

Aluminum Keyboard Function Keys don't work correctly

I just bough a brand new aluminum wireless keyboard and some of the function keys aren't working, from F1 through F7. F9 works like F3 should and F12 like F5. It's so bizarre. Otherwise the keys all work fine. I've updated everything, tried working through the forums workarounds on the aluminum keyboard, and so far it didn't work for my computer. I'm pretty frustrated. Has anyone figured out the solution? I'm running 10.6.7 and have updated all my software.

One last key combo to try, while holding SHIFT fn try toglling volume brightness... and see if that works. It'a been years since I've used anything but my built in keyboard.
At this point Run software update with the keyboard connected and see if there may be an update for that.
Try a SMC reset:
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
try a pram reset:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.
If still no joy, contact Apple, or go to the store and find out what you may need to do, This was the bullet in my gun, I'm sorry I could not resolve this for you.It's probably something simple, or maybe your machine is too old to suport this device.
Best of luck.
If they get you going, please post back so others may find out the fix:>

What are all the Function Keys for on my new KU-0841?

I just got an HP KU-0841 Keyboard and want to know what the Function Keys are for F1-F12.
Where can I learn about how to use them? Thanks

Hi,
Depending on application, or game. For example on one application which I use daily
F1 = Help (nearly all applications use this),
F2 = Slpit screen
F3 = End
F4 = Expand
F5 = Find / Re Find
F6 = Change
F7 = Up
F8 = Down
F9 = Swap
F10 = Left (one screen)
F11 = Right (one screen)
F12 = Cancel
Again, DEPENDING ON applicantion, you have to learn from application. Some applications allow you to re-program those keys.
Regards.
BH

Function keys don't work on New IMac with Leopard.. very sad

We just got a New IMac with Leopard at work and my F Keys don't work at all. I have tried everything, even checking the "Use all F1, F2, etc. keys as standard function keys", but it doesn't work at all. I use these keys all the time. How can I fix this?

WebWolf wrote:
My Bad, I am sure I am not the only one that has done this. I had not assigned the F Keys to their function under Exposé, I thought they didn't work after I turned on the F Keys under the Keyboard & Mouse window. So, I thought I would post this to help anyone else that did this.
They now work, yea!!!!
Sometimes we solve our own problems quite well
I believe that Leopard does reset to the default F keys.

Wireless keyboard function keys don't work even though updated

Hi,
like i read in different threads, many others had this problem too.
The function keys of my bluetooth keyboard (aluminium 2009) don't work even though i did firmware update for mighty mouse AND the keyboard firmware update. I also unset the option 'use function keys with fn......' option in system preferences. I also tried disconnecting and connecting the device. In system profiler the entry says it is (still) firmware version 80.
What can i do?
I'm thankful for any hint.
Best, Jörg

wrote this in another thread, but it is relevant here, too.
Wanting to buy a keyboard and reading this thread (and others), I went to a local Best Buy. They had quite a few of the wireless keyboards out. They had MC184LL(A) models and (B) models.
ALL of the (A) models worked perfectly with the iPad (typing, brightness, volume, ipod functions, etc).
NONE of the (B) models worked other than basic typing.
They had a stack of maybe 50 new wireless keyboards on the shelf. All but two of them were (B) models.
I bought one of the two (A) models. It is working perfectly on my iPad.

I am running SSH in Terminal window and my function keys don't work.

Hi all,
The company I am working in is using mainly Windows and they are running a database on Putty.exe
I managed to set up the SSH in Terminal on Mac OSX and I can see the database well and fine. Certain "commands" within the database are executed by numbers 1, 2, 3 etc while other "commands" are executed by function keys F1, F2 - F16 etc. However, when I press the F1 - F12 keys on my keyboard, they don't work as expected.
If any one has any expert advice, I would greatly appreciate it, thanks!

FInd out from your database administrator what terminal type the database application supports. Examples of terminal types are vt100 and ansi. Now go back to the Mac's Terminal Preferences and set the terminal to the matching type.

I have a Mac Mini, 7 years old, new keyboard function keys don't work. How can I correct this?

I've unclicked "use all F1 F2 keys as standard functions" and tried doing fn at the same time as F10 or F11 or F12, but I cannot control the sound from the keyboard. F10 darkens the background. F11 hides the windows I have open. F12 brings up the dashboard. How can I reset these to function as sound keys?

Just tried that. It didn't make any difference. I know it's not the keyboard; I went back to the Mac store and they tested it on a current computer and it worked exactly like it should.
It's a new metallic keyboard, replacing an older metallic one whose x, s, w, 2 keys just stopped working. It's a plug-in, not wireless.

Is there a reason the arrow keys don't work with ipad dock

Is there a reason that the arrow keys appear not to work with the ipad dock? I can understand if the citrix app needs an update (would be great to use with excel) but it also doesn't work with numbers the mac app. Is there a reason they are on the keyboard if they are not for use? Safari they don't do scrolling but really wanted it for use with spreadsheets. Can anyone tell me if I just need to switch on something in settings?

Hello there,
Not as such it is the iPad dock. It would be very handy for spread sheets.
Cheers

I had a problem with my mouse double(multiple) clicking when I didn't want it to, now pressing enter in a window like this will close the current window and open one of my Taboo sites, and the cursor keys don't work.

This happens in any text entry window, but there is no problem with Wordpad or Word or other apps, just in Firefox. It's like the keyboard mapping has gotten fouled up in Firefox, but I can't find where I might check what is going on.

You may have '''Switched ON Caret Browsing'''. press '''F7 (on Mac: fn + F7)''' to toggle '''Caret Browsing ON/OFF'''
* click '''Firefox''' button and click '''Options''' -> Advanced -> General -> remove
Checkmark from '''Always use the cursor keys to navigate within pages'''

Check and tell if its working.

Apple wireless keyboard function keys don't work with ipad2

I have a brand new ipad2 and just purchased an apple wireless keyboard. The keys work fine for typing, but the keys across the top don't seem to work at all. I play music, but none of the music control keys work. The keys on functions 1..12 appear to be totally dead.
I have seen several posts from people who seem to have this problem, but I see no answers. Did I purchase a lemon or what?

Something is setting the function keys, but I don't know what.

I recently installed Arch on a Lenovo T340s and I've been struggling with getting all the function keys to work. They all give out codes, but I can't seem to get them all to work with acpid. Those problems are a different topic/thread.
What's weird though is that some things are already set somewhere automatically and I'd like to figure out where.
For instance, there's a mute key which works both in X and in console. It's not set in /etc/acpi/handler.sh, neither have added any mapping for XF86AudioMute in Awesome, so it's not that either.
The suspend combination (Fn+F4) also works without any configuration and considering I could configure what happens upon suspend in systemd, I'd guess that it's configured somewhere there, but I'm not sure.
Same thing for wireless toggle (Fn+F5).
The point of me asking is that I figured that it would be a good idea to configure all of these keys in the same place.

Some of these could be hardware toggles and/or run from BIOS. The wireless definitely is - it willl not interact with your wireless management software, it simply toggles power to the transciever which can be seen with rfkill.
It's possible the mute key could also be a harware switch for the speakers - but I've never seen this done before. The fact that it works in the console as well would support the suggestion that it is a hardware toggle, but I'm still skeptical.
