Control key doesn't work

I had my late 2008 MacBook Pro's motherboard replaced by AppleCare after I messed up the USB ports, and when I got the computer back, the control key didn't work. I know it was working right before I took the computer in, and I think I noticed pretty quickly after I got the computer back that it didn't work. Does anyone know how that might have happened or how to fix it? (I've already checked to make sure I hadn't accidentally assigned control as a shortcut key for anything, and taken the key off to make sure there was nothing under it. The computer hasn't had any liquid damage.)

I tried booting into another operating system, and the control key still doesn't work. So the problem appears to be hardware-related. Any ideas?

Control key no longer works after update.

After updating Lion the control key no longer works. It beeps when pressing control and then a number key but nothing happens.
This is left control key though. Right still works?

Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software -- potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions -- they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are four lines of text in monospaced type, which are UNIX shell commands. They’re harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of running these commands, search this site for other discussions in which they’ve been used without any report of ill effects.
Some of the commands will line-wrap in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
To begin, launch the Terminal application; e.g., by entering the first few letters of its name in a Spotlight search.
Step 1
Copy or drag -- do not type -- the line below into the Terminal window, then press return:
kextstat -kl | awk ' !/apple/ { print $6 $7 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Step 3
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Step 4
ls -1A {,/}Library/{Ad,Compon,Ex,Fram,In,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Sta}* 2> /dev/null
Important: If you synchronize with a MobileMe account, your me.com email address may appear in the output of the above command. If so, change it to something like “[email protected]” before posting.
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
You can then quit Terminal.

Alt Key Doesn't Work With Tools

Suddenly the Alt key doesn't work with Clone and other Tools. When it's pressed, it shows a double arrow (black/white)cursor and a selection is not defined.
I did a forum search and found this
Q: My Alt key doesn´t work when using the Clone, Lasso, Magnifyer.. Tool.
A:
Some programs and utilities takes control of the Alt key when installed.
GuruNet (Atomica) and FlySwat are two of these applications. Uninstall them and re-claim the Alt-key, and all should be fine.
...but these programs are not on my PC. Plus, the Alt key works fine in other programs. I'm using CS.
I'm desperate to fix this. Any help is greatly appreciated.

Dear Awe,
>Crumbs in the board?
Thank you!!! My first thought on reading your msg was "You gotta be kidding". Then, "well, why not". So I did it and it worked. Amazing. Learn something new every day. In 18+ years of computer use I never had this problem (I've had lots of dirty keyboards, but never this problem). Must have been a big crumb. The only mystery though is why the key worked ok in another program. Anyway, a thousand thanks.
John, thank you for your reply too. I looked in the Regional Settings but couldn't find anything re keyboard mapping. I'm using XP.
Best Regards,
CJ

Functional keys doesn't work in Windows 7.

I have installed BootCamp 3.0 and installed all drivers; however, functional keys doesn't work such as keyboard backlight, volum control.
Let me know if there is any solution.
Thank you,

' Installed device in another PC with same OS. And it worked (seems like fine) with latest drivers from Creative site.
May be, the problem is that Setup doesn't delete old drivers or other stuff which conflicts with latest drivers? Before released drivers I tried to install beta and them didn't work. Yes, I uninstalled them and removed all drivers and software which I could with Device Manager. But it seems like it is installing well on "clean" system.

FN key doesn't work propertly on my Satellite P875-32H

Hi everybody,
I have problem like many others, FN key doesn't work propertly. Let's start from beggining:
1. I bought my P875-32H with Win8 64bit, and everything was allright.
2. After upgrade to 8.1 many probles issued and most of them I solved, BUT,
3. recently I found that FN key doesn't work in combination with
a) f5
b) f6-f8 (only with media player works, with winamp doesn't work),
c) f12 (I turned off wifi throught control panel, but indicator still flashing),
d) 1 and 2
e) y or z (US keybord)- keyboard backligth on/off-I try many solutions founded on forums (install driver from toshiba support site) but without success. Throught BIOS I turn on backligth but I can not turn off without entering in BIOS.
f) space-I have never used that combination.
I have tried on Microsoft forums but there is no solutions.
And one more question
Why my model P875-32H is not on dropdown list on toshiba support site?
Regards

At first I must say that I hope you have updated your machine following instructions on http://www.toshiba.eu/innovation/generic/windows8_1-message/
FN keys functionality is controlled by Toshiba specific tools and what you need to install or is already installed are Toshiba system driver and Toshiba function key utility.
FN+F5 key combination is for touchpad. Have you installed proper touchpad driver?
F6 and F8 are designed to work with media player. In the past (WXP) using small plug-in it was possible to use it for Winamp. I think something like this doesn't exist anymore.
You know it is not easy to say install this or that and everything will be OK. FN keys functionality is thing where several things work together.
Check please Toshiba download page on http://www.toshiba.eu/innovation/download_drivers_bios.jsp and install all necessary drivers, tools and utilities for Win8.1.

If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
Otherwise*, boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window opens.
Select your boot volume if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
 ▹ Restart
from the menu bar.
You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.
*Note: If you've activated FileVault, this procedure doesn't apply. Follow instead the instructions on this page:

How can I install CS5 on a new/replacement laptop? I paid full price in 2011 and have the key (and it shows up in my Adobe account under products), but it was a downloaded product and I can't find a download of that version online and my key doesn't work

Your key cannot work in CC, it's newer version, and would require a new purchase.

Left shift key doesn't work on some characters

In some applications, such as Excel and AOL, my left shift key doesn't work on some letters. Consequently, when I'm typing I get lower case letters when I've typed shift plus the letter to get a cap. Right shift works OK, but I'm not used to using it. It happens on i, t, and p, I've noticed so far. I don't know if it's the keyboard or the application. Word seems to work fine.
Would welcome any ideas on what is causing this and how to fix it.

Is it possible that you have inadvertently switched to a different keyboard layout? Open System Preferences, then click on the Language & Text preferences. Within the Language & Text preferences click on the 'Input Sources'. You should see a long list of languages representing the various keyboard layouts that are available. Make sure that only the keyboard language you use is selected. If there are multiple languages selected then de-select the extras.
If you continue to have problems then check the 'Show input menu in menu bar' checkbox in the lower section of the preference pane. This will place an icon in the upper right menu bar (it looks like a flag representing the language you have chosen for your input device) that provides additional options. I suggest selecing the 'Show Keyboard Viewer' option and then try pressing the keys that you are having problems with to see how they show up on the keyboard viewer graphic. If you've set the correct language for your keyboard and the key sequences still don't match, then you may need to take your keyboard in for service. Better yet, borrow another keyboard to confirm that the keyboard is the issue.

Lightroom 5 key doesn't work

I have purchase Lightroom5 upgrade version for MAC and just re-install my mac and install lightroom5. however, it said my key doesn't work. should i install lightroom 3 then install lightroom5 upgrade version instead of install lightroom 5 directly? where can i down load lightroom 5 upgrade version?

It is possible you downloaded a Creative Cloud version. Try downloading thru the page linked below. An upgrade version is differentiated by the serial number... the software itself only has one version.

Right-Command Key doesn't work

Well, on my PowerBook G4, there are 2 command-keys (I'm sure that's common).
My right command key doesn't work what-so-ever. I tried using the keyboard viewer and it doesn't turn gray either. Funny thing, but when I press the LEFT one, both cmd keys turn gray.
Well i dont know if its a missing driver or a setting, (maybe even a malfunctioning keyboard?) but if anyone can help I would appreciate it. Thanks.

Sorry, my bad. Haven't read through it in awhile and thought it affected keyboard too, but looks like just trackpad and other issues described. You may just have a bad keyboard or something lodged under that key.

Im cs5 but I have had this trouble in cs4.

causiu,
It is possible that the issues may be caused by preference corruption or interference from other applications.
You may try the following (you may have tried/done some of them already) and see whether it helps. Since you had it in CS4 too, the most likely is 5).
1) Close down Illy and open again;
2) Restart the computer;
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (irreversible);
4) Move the folder with Illy closed (reversible);
5) Look through and try out the relevant among the Other options, especially Item 7) with the usual suspects;
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool, and reinstall.
