Control key not working after repair

I took my macbook in over the weekend to the genius bar for them to look at the display hinge, from the paperwork it looks like in addition to replacing the display they also replaced the logic board and the wifi card.
I got the laptop home and the control key is not working. Resetting PRAM and NVRAM doesn't fix the issue, nor does fiddling with keyboard/universal access settings.
Is this a hardware issue? Do I need to make another trip to the genius bar?

Hm-m, I got exactly the same problem, got the logic board replaced today, and at home discovered that the control key is not working. Have you found the solution?

Some keybaord keys not working after suspect virus on Tecra A

Apostrophe, delete, semicolon and end keys not working after a suspected virus attack. I found record of the same problem on the net but apparently this guy fixed his problem after he found scroll lock or num lock on.
This is not the case here but there is something going on with numlock - register shows 2 and not 0. change to 0 but when reboot back to 2 again.
Suspect changed back by bios. I thought i couldnt get to bios because DEL key not working but found ESC works.
Tried to reset default values for bios but then cannot save and exit as this required the END key to work.
I was running XP at the time of the (suspected) attack and could not rectify the problem so put the computer back to the OEM status which i hoped would help - it did not, same problem so rather than install all the software on the computer again with XP i upgraded to Windows7 - fresh install.
Still keys do not work - it was a real pain to start with as my computer was set up to ctl+alt+del to log in and i had to do this with on screen keyboard - XP - this also showed that numlock was on before and after windows boot.
The reason i suspect a virus - my wife was watching one of her tv shows on line from home country (another toshiba laptop) and i needed to use that laptop for something else so i asked her to use mine - later on we turned the laptops off and in the morning turned tham back on again, the other laptop with AVG virus protection flagged several hits and this one with (FAMOUS and completely up to date) Norton flagged nothing - once i got into it using on screen keyboard.
Problems with this computer was found after scanning with a different antivirus.
Anyway - i am left with 4 keys that do not work on my keyboard (actually they did work after i logged into the computer for the first time but i had to hold them in for a long time - and then next time i rebooted, not work at all and havent ever since)
Any assistance here would be greatly appreciated, i have been working on this all weekend with no joy at all.
Thanks in advance.

Thanks Xardas,
I have essentially done both - tried Toshiba OEM status found on a small partition of the toshi hard drive - no good - then did a fresh install of Windows 7 - still no good
You know - as cunning as it sounds - i cannot reload the default settings in BIOS as it requires the END key to work so i can Save & Exit - all i can do is Exit Without Save - i sort of feel snookered at the moment.
Toshiba got back to me today and said that i have tried everything they would have (yeah for sure) and to take my machine into a service centre for a hardware check - yeah right on boys!
Check out this guys post below found on Kioskea.net - getting close to a year ago...

Hi there, I was hoping that you might be able to help me with the problem that I seem to be having with my Toshiba Satellite Laptop Keyboard too. For a few days now I havent been able to use a few of the keys on my keyboard, including (1) delete (the backspace key is still working though), (2) colon/semicolon, (3) apostrophe/quotation marks and (4) end (the home and PgUp and PgDn keys are still working though). Any suggestions?
Identical to my problem....obviously this guy had the same problem as well...see below - same thread.
yab - Feb 9, 2010 4:47am GMT
hi did you ever figure this out? i have the same exact problem...
However, i was not able to solve my problem the way this guy did - my scroll lock is not activated - it seems to work ok (on and off) i tested it using Excel to move around the cells.
yab ms ml - Feb 9, 2010 7:57am GMT
Nevermind. For me it was scroll lock. My apostrophe, semicolon, and delete keys are alive and working again. I hope you have the same easy fix.
Incidently - never hear from the first guy again - probably ended up being his scroll lock.
all sugestions welcome - sorry my smily face has no eyes -) guess why!

Re: NB200-134 - FN key not working after upgrade to Windows 7 Ultimate

My FN keys of NB200-134 is not working after upgrading from Windows 7 starter to Windows 7 ultimate. I tried installing every drivers found on Toshiba website for my lappy but still it does not work.
Help please

Hi asalamk,
The FN keys are controlled by Value Added Package and Flash Cards Support Utility. I think you have forgotten to install these tools
You should check the Toshiba page again and download both tools. Start with installation of Value Added Package then restart your notebook. After this install Flash Cards Support Utility. Once again restart and all FN keys should work properly now.

7 u j m keys not working after 10.8.1 upgrade, late 2008 aluminum Macbook

That's all, these keys do not work after update/upgrade today. They were working fine right before i did the update and are not working now. If I hit the M ket a few times i do get some garbage. Help?

Thanks, but still the same. It boot normally only if there isn't any usb device attach to the computer. I'm using usb mouse instead of bluetooth mouse and it happens not to boot normally like usual.
The technician said it would be okay if any usb devices attach to the computer during the boot apparently it won't boot normally.
Any alternative sir?

Brightness control keys stop working after booting MacOSX

I bought a new iMac 27" a couple of weeks ago, and I installed Windows 7 using bootcamp.
All the control keys (brightness, volume, etc) works ok on Windows until I reboot it in MacOSX. When i start windows again, brightness controls keys stops working, leaving the screen with the maximus bright, which is killing my eyes.
Reparing boot camp drivers doesn't do the trick. Am I missing something?

Try fn + the controls. It might be that Windows defaulted to those buttons as F1, F2, etc. Using fn while pressing the buttons will 'tell' Windows that it has to listen to the Bootcamp software and lower the brightness.

Keys (MJU) are not working after repair

Hello,
I've sent my MBP early 2011 for motherboard replacement, as affected model.
After repair service inform me some keys are not working anymore (MJU), thay asked me 290 euros for repair
What should I do? Anyone else had the same problem?

I never managed to get the keys to work again, but maybe I haven't been holding them long enough.
I have read somewhere that Apple ask for more than 300€ (USD 400) to change the keyboard, so I am considering opening myself my Crapple Crapbook Pro and change it myself.
I am quite ****** actually. A keyboard shouldn't die like this with no reason less than 3 years later. My Powerbook G4 that I used a lot much more than the Macbook is still working fine.

Brightness and volume control keys not working with windows 7?

brightness, volume control and some other keys keys are not working with windows 7 with macbook pro retina. Can I fix it?

Welcome to the Apple Support Communities
Have you installed Boot Camp drivers? You need them to make your computer work properly on Windows, and to use your function keys as Play or Pause, volume and brightness keys.
To install them, follow these steps:
1. Press the X key while your Mac is starting to start into OS X.
2. Open Boot Camp Assistant and tick only the option to download Windows support software.
3. Windows support software will be downloaded and Boot Camp Assistant will ask you to burn it into a DVD or USB drive, so do it.
4. Start into Windows, insert the DVD or USB drive and install Boot Camp drivers. Your Mac and your volume and brightness keys will be working after installing the drivers

Keyboard wireless key not working after upgrading to windows 8.1

Hello,
I am having hp pavilion dv6-6165tx notebook, where keyboard having a wireless button that turns ON and OFF all wireless devices, After upgrading to windows 8.1, HP Connection Manager is not getting installed, as well as Key is not working, key color turns red and white but no action is performed.
Kindly suggest me some solution.
Note: HP Doesn't provide drivers for windows 8/8.1 ONLY WINDOWS 7 for hp pavilion dv6-6165tx.
Thanks.

Hi @Jayesh_Bhadja ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv6-6165tx Notebook and the Wireless keyboard not working correctly. Here is a link to troubleshoot the keyboard.
The HP Connection Manager is something that is for Windows 7 not Windows 8.1. I would uninstall this from your Notebook. Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that need updating. It has a troubleshooting tool in this.
Make sure all your updates have been completed. I would try restarting my Notebook a few times.
If that does not help I would uninstall the keyboard from the Device manager.
Thanks.

AltGr key not working after upgrade to Xorg 7.3

So, I upgraded to Xorg 7.3, and everything seemingly worked fine.
Then I tried writing an e-mail address, and pressing AltGr+2 which should give me an (at) symbol didn't work. After fiddling about abit, I concluded that AltGr did not work at all.
I tried the suggested solutions in the wiki, but none worked for me. I also tried setting Option "XkvVariant "nodeadkeys", but no luck there either.
Here's the keyboard section of my xorg.conf:
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "no"
Option "XkbVariant" ""
EndSection
This worked like it should before the upgrade.
As you may have noticed, I have a norwegian keyboard. And if it helps, it's a laptop keyboard - I have a HP nc8430.
Pressing and releasing AltGr in xev produces this output:
FocusIn event, serial 28, synthetic NO, window 0x2200001,
mode NotifyUngrab, detail NotifyAncestor
KeymapNotify event, serial 28, synthetic NO, window 0x0,
keys: 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
I'm not entirely sure if this is relevant tough.
Any help will be greatly appreciated.
EDIT: I should perhaps add this:
I'm not using a composite manager like Compiz or Beryl, and I do not have composite nor AIGLX enabled in my xorg.conf.
I'm using the fglrx driver.
Last edited by sunn (2007-11-07 16:28:46)

It seems the problem has resolved itself. I did a pacman -Syu today, and although only libsamplerate was upgraded, my AltGr key functions properly again. Kind of weird, as libsamplerate seems to have something to do with audio.. But hey, it works, and I'm not complaining.

Keyboard delete and caps lock keys not working after update

Shortly after a windows update two keys, delete and caps lock do not work. I have tried the following
1. system restore..it says it cannot restore as a file is missing. I have used this function before without any problem.
2. Update key board driver (standard PS/2)..it says latest version is installed.
3. Uninstall and reinstall.
4. Reset using the remove batteryt hold down power key option.
The caps lock and delete does not work in Notepad or MS Word.
It seems unlikely that the two keys themselves are damaged as it is unlikely that they would both fail at the same time and the problem after the windows undate is suspicious.
I am using Windows 7 Home premium on a 64 bit HP G62.
help appreciated as ever
thanks

Here's another test...since your laptop has USB ports get or borrow a USB keyboard and try it and if all those keys work and test then the results would mean your laptop keyboard has stop functioning as least you narrow done the problem.

Keyboard: audio and Brightness control keys not working with or without fn

The Keys for controling Audio and Brightness (F1-F5) do not work.
Also combined with pressing the "fn" key the keys do not work.
So i only control audio with the remote control or the slider in the menubar.
Making a reboot with deleting pram didn't help.
I'm running the up to date version of leopard on a macbook pro (core2duo).
I also searched in the forum for this problem.
I oten read about "sytem control"-"keyboard and mouse"-"keyboard" and the F1, F2, etc. to use as...
but switching this button on or off doesn't change anything.

problem solved:
the couse was the software update 1.1 for macbook pro, because there i had the problem like in this thread: http://discussions.apple.com/thread.jspa?messageID=6142512&#6142512
and did the solution like that, but there i maybe made some mistakes with renaming and copying, so i rinstalled the update and renamed it a copied to plugins, and now all works as it should.
thanks for help
