Volume and eject keys are not working!

Hello, i have a problem with my USB apple keyboard that come in pack with my iMac. When i turn on the computer everything is working fine but after using it for about 10 minutes my volume and eject keys stop working at all. What can you say about that? And when i disconnect and connect the keyboard from the computer it starts working again but not for a long time thought.

Hello Folks,
Got my super new 20" duo and i a having exactly the same problems. Volume keys don't work randomly, mouse stops responding and eject works most of the time but I have had problems.
Tried different usb port getting the same.
Will try another k'board and see if that makes a difference.
I have seen another post else where and the chap got a replacement from apple. His mouse wouldn't function sparadically.

Try an external keyboard. If it works, you need a new internal keyboard.

Hi,
While this could be a hardware issue, it's always worth trying the following.
Open windows Control Panel, open Device Manager, expand Keyboards, right click the entry 'Standard PS/2 Keyboard' and select Uninstall.
Shutdown the notebook.
Then unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f9 to load the defaults ( this is sometimes f5, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Regards,
DP-K

Volume and Eject Keys No Longer Work After Boot Camp 2.1 Update

Earlier this evening I allowed the Apple Software Update app in Windows to update Boot Camp to version 2.1. I allowed the computer to restart following a successful installation of the update. I've restarted two more times since then. Ever since the update (including before the computer restarted for the first time following the update), the volume and eject keys on my keyboard don't work. I also have an Apple Wireless Keyboard (one of the 2003-2007 era white/clear ones) and it exhibits the same problem. Both keyboards otherwise work fine. The computer also otherwise works fine, and there's no evidence of any driver problems.
Some other potentially relevant information:
1- The Boot Camp icon is no longer present in the Windows System Tray.
2- The Boot Camp Control Panel is still present in the Windows Control Panel and it works fine.
3- All settings in the Boot Camp Control panel are unchanged from their defaults. In particular, I have confirmed that "Use all F1, F2, etc. keys as standard function keys" is still unchecked.
4- The Windows Device Manager properly recognizes both keyboards as Apple Keyboards.
I'm using Windows Vista Ultimate on an early 2008 MacBook; system specs are in my signature. Any ideas?
Thanks for taking the time to read this, and double-thanks if you can respond with any suggestions!

Ah, the joy of working with computers...:( Apparently, from my woes with the same problem, the Apple Keyboard Manager is rightfully entered into the Run directory in the Windows registry at HKLM/Microsoft/Windows/Current Version/Run.
Why it doesn't start I still have to find out, but this may be because I have Parallels Workstatio installed as well and switch back between a virtualized Windows and a Bootcamp Windows. However, after installing Bootcamp 2.1 first and then SP3 IN THE BOOTCAMP ENVIRONMENT everything seems to work, except the Energy Options taskbar icon and Apple Keyboard Manager.
Will keep you posted on any progress I make.
Apple Support, BTW, was absolutely abysmal, with them even refusing to accept the ticket at all, on the grounds that they have no knowledge about Windows. Apple, get your support fixed!

Satellite C50-A-15Q - arrow, question mark key and z key are not working

I have a Satellite Pro, C50-A-15Q. All keys were working fine yesterday, today I turn the laptop on and the arrow keys, question mark key and z key are all not responding. Any idea how I can fix this?
I have tried turning the laptop off and on, hoping (naively) that this would fix, but to no avail.

As Tom already wrote, it is not easy to say for sure if this malfunction is result of defective keyboard or maybe keyboard controller. In my opinion troublemaker is the keyboard itself.
Have you maybe updated BIOS or done anything that could be responsible for this?
I presume your notebook is pretty new model with valid warranty so best option for you is to contact nearest Toshiba service provider and ask for help.

My O, L, and '.' keys are not working!

I have a question. I have a PowerBook G4, 1.5 GHz, Aluminum. Recently, my "o", "l", and "." keys are working intermittently. Half the time, they do not work. This is not a software problem as I have an external keyboard. Does anybody know what's going on??? I don't.

Sounds like a cracked trace on the keyboard PWB. Best to just replace the keyboard. You might get more information at this link:
http://www.powerbookmedic.com/Powerbook-Keyboard---G4-Aluminum-p-16506.html
Replacement can be a bit involved:

In this case, the Titanium models have the Aluminum models beat, as replacing a Titanium keyboard is a 2-3 minute process, tops.

'u' 'j' and '7' and '!' keys are not working?

The 'u', 'j','7' and '!' are not working. The phone has recently been repaired after getting wet - new battery and screen. Any ideas why not working?

Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears)
See if that helps.

Caps lock, delete and tab key are not working on my Apple wireless keyboard

I see that a lot of users have had this same issue. I have tried all the "tricks" suggested, but keys are still not functioning.

Try a smc reset
http://support.apple.com/kb/HT3964
Try a pram reset: power off, power back on holding the keys: option, command, P ,R (no commas) press them before the start chime, and hold them till you hear the start chime 32 times, then release and reboot.
If still no joy try a safe boot, power off, power back on holding the shift key. Continue to hold the shift key till you see the progress bar, let it finish booting, and see if t works.
The code thing is wierd.
If none of these help your issue, bring it to an APPLE store or a AASP and have it checked out it have a bad top, or logic board/HD.

I have Late 2011 Macbook Pro and zxcv keys are not working?

I have late 2011 Macbook Pro and the zxcv keys are no longer working. Once I connect USB keyboard I can utilize these keys. Do anyone have solution?

How did you try to use Acitivty Monitor?
Open Activity Monitor, choose "All processes" from the list, and sort processes by CPU usage. More likely than not, there will be task using up good bit of CPU.
You could also try resetting SMC:

Volume and FF keys do not work on wireless keyboard

I replaced a wireless keyboard for my iMac today, and just noticed tonight that when I try to adjust the volume UP, it sends me to widgets, and when I try to adjust the volume DOWN, it dims the desktop behind my open window.
I've tried checking, and unchecking, the box in Preferences>Keyboard>Use all F1, F2, etc. as standard function keys. I've also gone to keyboard shortcuts and disabled F7 to F12. But no volume or rewind/ff etc.
How do I get my volume and rw/ff keys back? Thanks!

Also, I have attempted to submit a repair claim online as I have the Apple Care for the iMac but when I go to enter the Hardware Serial Number of the Keyboard in the Wireless Keyboard repair section, it does not recognize it.
Dustin,
Welcome to Apple Discussions.
I would recommend entering the computer's serial number not the keyboards. You can locate the computer by clicking the  in the upper left corner of your screen, clicking About this Mac, and where it states the Version click 2x until the serial number appears.
Regards,
Roger

Satellite Pro C650 - arrow, slash, and z keys are not working

Can any one help - my slash keys, arrow keys, z and question marks have stopped working.
I have seen several other posts on various forums for exactly the same combination of keys.
I have a Satellite Pro C650.

Sounds like a keyboard malfunction.
Can you use the external USB keyboard properly?
If you did not notice the same problems using external keyboard, then I would recommend replacing the internal keyboard.

Is this a hardware problem?

Then I wouldn't think it's to do with the Arch, updating does not stop parts of the keyboard working for the bios as it's separate firmware. When you can access the bios after first turning on, your PC has not yet accessed the hard drive to load the drivers for the operating system yet. Also as far as I'm aware Arch (or any other operating system in fact) has never updated the bios firmware.

Hello, I have an Apple wireless keyboard linked to an Ipad Air. The M J U and 7 keys are not working, Is there a solution, Thanks

Hi, Has anyone else encountered this problem. I see mucg discussion of this problem with MacBooks, but none relating to use with an IPad.
Thanks

I am having this problem as well. I hate to just wait and hope Apple will fix the problem, but I'm not sure what else can be done. We can't be the only people experienceing this, can we?

Try hitting '''F7'''.
