Some keys stopped working for one user account

Dear all,
since a while (I can't say since when exactly) some of the keys stopped working: left control, left shift, and the tab key. In the beginning the caps lock didn't work as well, but it was my own setting. All other then the three listed work OK. As described in some KB articles I checked all settings for universal access, localisation, keyboard, mouse, and keyboard-shortcuts (all standard). I completely disassembled the keyboard (aprox. 50 screws!) cleaned it and checked the connections between the keys on the printed circuit. Everything looks good. Then my wife told me that she does not have the problem and indeed, in other user accounts it is all working OK. It means that it should be a setup problem in my profile. The keyboard viewer is showing every activated (pressed) key, but not the three that are not working - which is only consequent. When I disable the caps-lock then the keyboard viewer doesn't show this key being pressed either. My conclusion is that there must be a keyboard filter below the application level. Now I'm stuck.
Help appreciated!
Cheers,
Kurt.

Yup, odds were against me choosing the right item on the first go
Log back into your problem account.
Here's the whole litany for thoroughly checking your home folder. It's not as daunting as it looks.
1. Go to Users/yourname//Library/Fonts - drag this folder to the desktop.
• Restart and test your applications.
• If they work start adding the fonts back few at a time.
( Likely suspects are Times RO, Helvetica Fractions and Times Phonetic, also if you do not use Classic you can trash the classic fonts.) If not, put your Fonts folder back.
2. Check Preferences Thoroughly;
• Go to ~(YourHome/Library/Preferences drag this folder to the desktop.
• Restart and test your applications.
• If this works, save the old preferences folder somewhere else or on disk, name it "old prefs" .
** Note: A very important file is the "com.apple.Mail.plist" preference file located in the Preferences folder which contains all email account settings and general mail preferences (hold this one and replace if your problem is not with Mail).
You'll have to go through some of your System Preferences and apps to set the preferences back to how you like them. (Or if you have the time and inclination, "cherry pick" through until you find the problem one or two.)
3. Check Permissions Inside Home Folder
• Navigate to YourHome/Library.
• Get Info (Command - i) on folders for apps you are having problems with.
• Open the "Ownership & permissions" disclosure triangle.
• Make sure you are the owner, with "read and write" access.
• Click on "apply to all"
• If this is correct, open the "Applications Support" folder and do the same procedure (Command+I) for the folders with the names of the applications you are having trouble with.
(Note:The reason to check this is because repairing permissions with Disk Utility doesn't touch permissions inside your home folder.)
4. Navigate to YourHome/Library/Caches and drag this folder to the trash, then log out and back or restart. There is no need to replace this folder.

Some Keys stopped working on my Macbook pro (mid 2012). Can someone help me please?

Hi
So keys 1,2,3,4 stopped working. All other keys are working fine. I tried doing some troubleshooting myself but none worked. As far as I can see the keys do not light up on the on screen keyboard when pressed. Do you know of any troubleshooting I can try to fix this problem.
Please note there was no spillage or any abuse to the keys what so ever. The keys just decided to stop on their own. Any help is appreciated.
Thanks

OS X Mountain Lion: If keys on your keyboard don’t work

Some keys stopped working on my HP X18-1027CL

This morning, some of the keys on my HP X18-1027CL Notebook stopped working.
I cleaned the keys with rubbing alcohol, reinstalled the drivers, and the control panel has said that there is no problem,
The keys still do not work. I think it may be broken circuitry, but I have not spilled anything or even moved the computer since it was last working.
The unresponsive keys are mostly in the 3rd row. They are caps lock, a,s,d,f,j,k,l,quote button,enter (although the enter button on the numeric pad still works),b,n, and the spacebar (although the computer sometimes acts as though the spacebar is being held down after one of the working keys has been pressed).
I'm posting this in multiple forums, since I don't know if I need a software or hardware based solution.

Keyboard: some keys not working

Some keys not working. Need help/suggestions. Not great with computers so PLEASE give details/steps re: how to do what you suggest - thanks!
Details: intel based iMac running snow leopard 10.6.8. Apple wireless/bluetooth keyboard (came with the iMac).
Some keys suddenly stopped working: space, tab, capLock, option key to the right of space bar (one on the left works), down arrow
The problem happens in various programs (safari, pages, etc)
The keyboard is fine on another iMac
A different keyboard is fine on this/the involved iMac
(nutshell: keyboard works fine - computer works fine, unless they're together)
Here's what's been tried/checked:
-checked the settings for universal access ("mouse keys" are off) and checked for any bluetooth keyboard shortcuts.
-in system preferences "speech" is not set for "speak selected text when the key is pressed" - this is not checked/selected
-tried creating a new user but had the same issue so it's computer-wide rather than just a user account
-removed the keyboard and reconnected (using the +/- signs and "disconnect" and putting in a new code of numbers to pair keyboard)
-language/text is set for english
-did the keyboard viewer and the keys in question did NOT highlight when pressed (but don't forget the entire keyboard is fine on a different computer so thekeys aren't the issue)
-"slow keys" is turned off re: keyboard in system preferences.
Any help is welcomed. It's frustrating knowing the keyboard works, just not with this computer. Please help. Many thanks!

yes - not sure how this works...if you can see my original post there are a lot of details in there. If you can't...
nutshell: the keyboard works on a different iMac
             a different keyboard works on this/the involved iMac
             I tried to create a different user and the keyboard still does not work so it is computer-wide
             I also removed the keyboard from the computer (using the +/- symbols and disconnecting and then repairing it. The problem remained
Thanks for any help. It's crazy that the keyboard is fine and the computer is fine but together, there's the problem.
Thank you!!!

My return and shift key stopping working

my return and shift key stopping working. It wont go to the next line or function as an enter.
Now, most of the time it wont do anything but if you push it several times it will type a 0p or /- or control volume the instead. I checked the keyboard setting and voicecontrol and reset it to default and updated software for system but no resolve. How do I fix this?

Hi -- I have this problem too. I cleaned out the keyboard, did an SMC reset, a PRAM reset, and also followed the steps I could follow from this article, linked to in the answer to another question:
http://support.apple.com/kb/ts1381
no luck with any of it. Could we please have some advice targetted at the specific problem of nonfunctional shift and return keys on a MacBook Air?
In the meantime I'm using only the left-side shift and have downloaded and installed KeyRemap4MacBook and remapped my backslash key so it issues the "return" command. A clunky work around but it seems to do the trick, at least.

Windows 7 ESC key stopped working

I've got a fully patched Windows 7 Professional Desktop computer that I've been using for over 2 years. Yesterday my ESC key stopped working, which I first noticed when using Outlook and tried to close an open email window. I checked the keyboard
by moving it to another Windows 7 computer - works great. I also noticed that other keyboard shortcuts that utilize the ESC key still work, like for example pressing Ctrl / ESC brings up the Start menu. The problem is limited to functions that
operate off the ESC only - like closing an open email in Outlook or closing an open photograph on Facebook.
I downloaded a keyboard testing app that shows the key not working. But when I install this program on another computer and move the suspect keyboard - the program shows that it does in fact work.
I suspect something is wrong at a registry level - some entry has hijacked the key mapping. I've spent several hours on Google looking at various suggestions - all to no avail. I've tried updating drivers as a last resort - no change. Remember,
the ESC does work when used in a sequence involving multiple buttons. Any suggestions?

I've encountered a similar situation regularly: my Esc key just quits working in mid session, and I always forget what the cause/fix is.
I have this same keyboard for over 8 years now, and it always works fine, so no, it's not a hardware issue - these issues typically never are. Rebooting the PC always solves the issue, but rebooting a dev workstation, with a gazillion apps open is a PITA.
Turns out in my case it's always Photoshop CS2 that 'kills' my Escape key; as soon as I close Photoshop, the Esc key functions normally again.
Another issue I get is the Ctrl/Shift/Alt keys sometimes quit working; again, a reboot always fixes the issue, but rebooting is always a last recourse. Usually I just mash the Caps Lock/Ctrl/Shift/Alt; sometimes it works, sometimes it doesn't and I need
to reboot...

My "9-o-l-." keys stop working after startup, and spreading! ahh help?

My "9-O-L-." keys stop working after startup and my arrow keys too.
Sometimes when I start up the keys will work for a bit then one by one stop functioning and then randomly work every so often, then it seems to "spread" to the right shift key, and sometimes the "8-I-K-," keys.
Around the same time when this all began my Battery completely stopped working too, does this have anything to do with it? I've reset my PRAM and no luck.
I'm planning on replacing the keyboard, will that fix the problem? or is it something deeper?
Thanks in advance!
-Andrew

I assume you've rebooted? Can you control the computer well enough to make a new account and log into it? Doubt this will fix it but maybe. The keyboard may need replacing but it might also be that the cable has worked loose so that some of the wires have disconnected but not all. Sounds like a trip or call to Apple is in order.

Satellite A105 Shift Keys stop working after BIOS update

I have a stack of laptop boards from the A105 series (Intel chipset) that I received with bad BIOS's. Two worked, and I updated the BIOS's on them to fix CPU compatibility issues. After that, the shift keys stopped working, and pressing Shift-A causes the power light to dim. Reverting to ANY previous version BIOS, whether through the Windows program, CD, or Crisis Recovery floppy (magic key is "F", not "B", "Esc", or "U"), does not fix the keyboard problem.
To make things more confusing, I did notice that the one single BIOS that seems to actually correct the problem is version 1.50, which I haven't seen available for any Tecra A7 or Satellite A100/A105, except a couple A100's, but the BIOS file is much too small and can't be loaded.
Does anyone have any idea why these Intel-based boards are doing this? Or does anyone know where I can get a usable version 1.50 BIOS?
For the sake of this post, please consider my skill level to be high. (In other words, I would be thankful for people trying to help with "Replace the keyboard", but I have about a dozen keyboards, all of which I have tried, and all of which work on other laptops. Additionally, if you have just a theoretical solution, I'm definitely open to hearing it. Also, if a Toshiba tech would like to reply, I would very much appreciate it!)

Hi, thank you for your help.
Some motherboards were not in chassis when I got them. Is there a place the PSAAxx model number would be written on the boards?
Four PSAA8U (Two A105-S4334 and Two A105-S4014) - Intel Chipset, fingerprint reader. Tried BIOS Versions 1.40, 1.70, 2.00, 5.10, 5.60, 5.90, and 6.00. Shift keys do not work on either one.
Two PSAA2U (A105-S2091 and A105-S2031) - ATi Chipset. BIOS versions 1.50, 1.80, and 2.30. Keyboard works.
Another PSAA8U (A105-S4184) - Intel Chipset, no fingerprint reader. BIOS version 6.00. Keyboard works.
I noticed that so far all of the models with fingerprint readers have the problem. All of the ATi Chipset boards are working fine, but they have significant processor limits. I am in the middle of updating the BIOS in another Intel one using a Crisis Rescue Disc, so after that finishes I will try disconnecting the fingerprint reader to see if it has an effect.
I don't think the keyboard controller is faulty, because these boards all failed on the same day. I have tried updating the BIOS using WinPhlash, Phlash16 in DOS, the install CD, and a Crisis Recovery Disk. I set the defaults in the BIOS almost every time, and I also have tried holding the power button for 60 seconds with the power cord unplugged and the battery removed (as some people have suggested.)
The shift keys don't work in DOS, Linux, Windows, or even in the BIOS. I test it in the BIOS by using Tab to cycle through the fields in time of day, then Shift-Tab to cycle backwards. This works with a USB keyboard, and it also works on the ATi chipset models and the Intel chipset models that are still working.
Thank you for your reply. (-:

Volumeicon volume keys stop working after adjusting volume via icon

When Volumeicon is first started, the volume keys work fine, (although it doesn't show the volume bar like it does when you scroll on the icon for some reason). When I adjust the volume by scrolling the mousewheel on the icon, the volume keys stop working and volume can only be adjusted via scrollwheel. Volumeicon must be restarted to restore volume key functionality.
Why is this happening? What's going on?

Is this something that worked previously but then stopped working correctly?
What window manager / desktop environment are you using?
If you start volumeicon from the command line then use it are there any error messages?
Alternatively, does the volumeicon-gtk2 packagen in the AUR work better?

Backslash key stopped working

My backslash key stopped working a couple of weeks ago. Until I get it fixxed, is there a way to remap some other key to this character, as least for using vim in Terminal.app?
Thanks. I feel that I should know how to do this, but I haven't the foggiest notion of where to start.

Hi Yepix,
Boot the system into safe mode and check for the issue, also check in onscreen keyboard if it works. If still the same issue it might be issue with the keyboard hence suggest you to visit the nearest authorised service centre.
Click here to open a link where you can select the country and get the exact contact support number. I’m sure they will be a great help.

Launchpad key stop working?

The launchpad key stop working on my macbook pro 2011 and i have tryed every thing and the only thing that work if i push the fn button and F4 so i just want the launchpad key to work again with out the fn key please if some body could help me..........

Hi.
Re. " The command does not delete any of your specific keyboard shortcuts you have defined. "
Umm, sure it does. This unix command deletes the preferences file that tracks all of the keyboard changes that you make.
So, write down (snapshot) any/all functions so that you can re-assign them.
-Alan
Ps: The only exception to this are any "Application Shortcuts" hot keys.
