Caps Lock Problem.... suddenly works reverse of expected

Hi all,
I have had my PB for four months and use it constantly. I just had a strange thing happen, suddenly the machine types in ALL CAPS by default. When I turn on the Caps Lock button (and the light goes on as expected) then the keyboard types lower case.
All is fine, except the Caps Lock functionality seems to be reversed. Light ON=Lower Case... Light OFF=UPPER CASE.
I have already repaired permissions.... I do not have any third party modifications or applications that modify the OS.
Pluggin in an external keyboard operates as expected, but the built in keyboard still misbehaves.
Any thoughts?

I just had this exact problem occur to me a few days ago. My cap locks key reversed itself somehow. In other words, when it was engaged I got lowercase; when it was not, I got uppercase. In addition, some keys, like the apostrophe and quote key did other things.
This issue occurred after I ran disk utility and mac janitor in the morning, which I do every Friday am. I decided to re-run both programs later in the day and the issue dissappeared.
I was already running 10.4.6, so I don't think it has to do with the OS. Hope that helps somebody.

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.

Shift-Caps Lock-Tab not working with remapped Caps Lock

I've remapped my Caps Lock key to Ctrl using the Preferences > Keyboard > Modifier keys dialog and in the following question when I say CTRL i mean the Caps Lock key remapped to Ctrl and Ctrl is the normal left Ctrl key.
I'm using OS X 10.9.4 and I've just bought 2 new external corded Apple keyboards and both of them are having trouble with the key combination Left Shift + CTRL + Tab. For applications where that combination should go to the previous TAB it does not work. If I use the right Shift instead it works fine, if I use the left Ctrl key instead of the remapped Caps Lock key it works great too.
The internal keyboard on the laptop works fine with Left Shift - Caps Lock - Tab.
The computers are a Macbook Air 11" Mid 2011 and a Macbook Pro 15" Mid 2010.

Hey,
Sorry to hear about the keyboard problem.
In a post a while back had this to say. He makes a suggestion that the keyboard might need to be replaced, then the person with the question tried something else. You might take a look and see if there's something there that will help.
Thanks for coming to the forum.

HT1192 Caps Lock is not working in my mac, after pressing long time too.

Caps Lock is not working in my mac, after pressing long time too.Please help me to sort this problem out.

I think even in newer versions of OS X there is a slight delay; just not so pronounced. My advice to get around it would be to install PCKeyboardHack and KeyRemap4MacBook - then do a couple of things:
Change the Caps Lock key in System Preferences > Keyboard > Modifier Keys to "None"
Use PCKeyboardHack to remap Caps Lock to keycode 110, the PC Application Key, which is unused on Apple keyboards.
Then use KeyRemap4Macbook to map that particular keycode to Toggle Caps Lock.Try selecting For PC Users > Change PC Application Key > Application Key to CapsLock.
I'm pretty sure that should get rid of the delay, which only happens when Apple is in charge of connecting the Caps Lock key to its action.
Really, though, I would personally recommend doing some much more awesome things with your Caps Lock key; it's prime keyboard real estate, and who uses caps lock anyway, except in the darkest corners of the Internet? Personally, I've remapped Caps to be Escape (for use in my text editor) when you press it by itself quickly, but to be Cmd+Opt+Ctrl+Shift when you press it with any other key. I call it the "Hyper" key, and use it to switch applications; Hyp+S = Safari, Hyp+D = email, Hyp+F = Finder... The point is, be creative, make the Caps Lock key work for you.
Oh, and the real Escape key maps to Caps Lock, so I can use it if I want to.

Caps lock doesn't work.

My caps lock doesn't work. Whenever I press it, the cursor disappears from the type box on a website or whatever I'm typing information on. I then have to use my mouse to click back to where it should have been. In the meantime, I have been using the "shift" key to capitalise. This isn't just confined to Firefox, but to IE, Word etc. How do I solve this problem?

Hello again, iamjayakumars!
I didn't press the "shift" key for a long time. Just a brief period when need be to capitalise one word or more. This caps lock problem occurs everytime I turn the laptop on.

Apple wireless keyboard. Caps Lock light quit working.

I know it's a small thing but all of a sudden the Caps Lock light quit working. A real pain for entering passwordssince you can't see if their in caps or not. Can this be fixed?

What does resetting the PRAM mean? How is that done?
<http://support.apple.com/kb/PH11243>
It works best with a USB keyboard. With a wireless keyboard, try pressing the keys just after the startup BOING.
You will need to reset the "Startup Disk" system preference after a PRAM reset.

Caps Lock LED not working in X unless I hold shift

Hi, I recently installed Arch, installed X and configured it as the wiki says, installed awesome and now I switched the language toggle to Caps Lock instead of Alt+Shift.
I hoped the LED would tell me what language I'm typing in. But I noticed the LED wasn't working (Num Lock LED does work however).
I looked on the forum and it said to use
kbd_mode -u
to switch the keyboard to UTF-8 and it'll be fine.
Now Scroll Lock works too (it didn't before), but Caps Lock does something weird, it lights up for a split second then immediately turns back off. That unless I hold shift when I press Caps Lock, then it works fine, but I don't want to hold shift...
So how can I make it work?
EDIT: In the tty Caps Lock works fine.
Thanks.

Standard troubleshooting procedures in order are power the iPhone off and on, Reset, Restore and if no change after and or all in order, call AppleCare (800) 694-7466 or make an appointment at an Apple Store if there is one nearby.
Although others may have experienced the same, this does not mean the majority have.

CAPS LOCK problems

Hello there!
My 2008 Mac Pro 1,1 running Mac OS X 10.6.8 is having problems with CAPS LOCK, but not necessarily the caps lock key. Every once in a while my computer will suddenly think the SHIFT key is being pressed, and there's no way to "unpress" it, so to speak. Everything I click and type is as if the shift key is being pressed, and the only way to fix this issue is to restart the computer. Even if I do that, there's a chance that the issue will return only a few minutes after I turn the machine back on.
It doesn't seem that I'm doing anything in particular to trigger this unusual behavior, and it seems to be a random occurance. I do have a theory that it has something to do with the computer being used for extended periods of time, as it seems to happen more often when I'm doing a lot of video and graphics work for hours at a time.
I did, however, add some RAM to my computer a few weeks ago, which I had ordered from crucialmemory.com.
Has anyone else experienced this problem or know what might be causing it?
Thank you in advance!

Hi Grant! Thank you for your response, but sticky keys seem to be off when this happens.
If it helps, whenever this issue occurs and I bring up the on screen keyboard, the shift keys are displayed as permanently pressed down. This also happens when I switch keyboards, so I know it's not any individual keyboard that is causing the problem.

Caps lock problem on Leopard MacBooks

I bought a new Santa Rosa black MacBook two weeks ago. It was great, except that the caps lock key would intermittently not work. The Apple Store swapped the machine, thinking that this might be symptomatic of a logic board problem. But the new machine does the same.
There have been a number of posts about all the keys on Leopard-installed MacBooks sometimes not responding. But is anyone else experiencing the caps lock issue in particular?
I'm wondering whether this is a Leopard issue or whether I've been unlucky in having the same hardware problem on two machines.
Installing 10.5.1 makes no difference, incidentally.

I have the same "problem." I just bought a MacBook, which does not seem to be right. The caps lock does NOT toggle. If you keep clicking caps lock key, you should see the light going on and off repeatedly. But, it does not. For example, if you click "caps lock" and "key A" one at a time, then you should see this: AaAaAaAaAaAa ...
A weird thing is that when I type in anything usually, I do not have any trouble in typing, which is good.
Anyway, I went to Apple store nearby to check what the other MacBooks work. They are all the same or their caps locks do NOT toggle. Okay, it is "normal." I admit that. This is really annoying.
I had other problems with the macbook (macbook won't safe sleep on low battery).
I basically have given up buying this macbook and will wait for a while. All macs that I have used have been okay. My expectation to Mac may be high, but this macbook is so weird.
Thank you,

My caps lock was stuck and I shut down. Now it's coming back up in safe boot and asking for a password. It won't take my password, I believe because of the caps lock problem. So, how can I get in?

My caps lock was stuck when I shut down my computer. It is coming back up in safe boot (I had spilled liquid on it).
It's asking for my password - which has some lower case letters...So now how can I get in?
Is there a way to change this password or something?
I have a wireless keyboard, but it wasn't set up - so, It's not recognizing it.
Any ideas?

Take your computer to get the keyboard replaced, your lucky it didn't trigger the moisture sensor and brick your machine, so your chances of the machine working well after the keyboard is replaced is likely very good.
As long as the main keyboard is sending a caps lock signal, it's not going to work even if you get in.
If you need to remove files off the internal drive, use a Firewire cable (800 to 400 adpater may be needed) and hold T to boot the problem Mac into Firewire Target Disk Mode and connect the cable to another Mac, the hard drive will appear on the desktop which you can then remove/erase files.
