Caps Lock lights up but doesn't work in Mac OS (but does in Windows)

My Caps Lock button lights up but caps do not work in any Leopard programs. If I hold down the Shift key then caps will work.
However, I have Parallels and caps lock DOES work when running Windows.
I checked the Modifier Keys settings in keyboard preferences and they are set to the default.
I am new to Apple and have a Mac Book Pro that I bought in Spring 2008.
I searched the discussions but didn't see my situation...

Hi Steve, Welcome to apple discussions.
Hmm, that is a strange problem. Well, you've already done what I would suggest which is to go to the keyboard settings and click the "Restore defaults" button in the modifier keys window and try again. If that doesn't work then you can restart the computer and check. If that doesn't work you can try to reset the pram. Hold the optioncommand+PR buttons after you hear the startup chime, it should chime again, I let it chime a third time just for good measure and see if things look better.
If that fails then you can try making another account and seeing if the caps lock works in the new account. There might be some strange error on your account that would be corrected for in a new account. After that it gets more labor intensive. Do a system re-install, do an erase and install.
You might consider a trip to the apple genius bar there in Honolulu if can. The should be able to run through all that for you. You're still under warrantee so take advantage and get some help.
Oh, and just a disclaimer that I learned from Adam on the maccast podcast. Make a full, complete backup including a time machine and bootable (like superduper or carbon copy cloner) disk before you do any of the above or take the unit it for service.
Hope this helps.

Account doesn't work on Mac Mail but does on iPhone

I have a IMAP email account with my company that works on my iPhone and in Entourage but doesn't work in Mac Mail. I have tried to copy the settings and even did a full erase and reinstall of Leopard and no one has an idea why it won't work, the hosting company or Pro Care. Any idea out there?

No idea what "My apple ID account doesn't work on my itunes but it does on the web" means.
Please explain

I got a external Apple Wired Keyboard (w/ NumPad), caps lock mapped to control doesn't work with tab + caps lock + shift

I got a external Apple Wired Keyboard (w/ NumPad) since I'm a developer. I have used control panel > keyboard > modifier keys to make the caps lock key the control key. I can't get it to work when I press caps lock (which maps to control) +shift + tab (which I use to change tabs backwards).
Any ideas? It works when I use the regular control key, and it works on my built-in MBPro keyboard. Thx!

Caps Lock light on MacBook Pro not working.

The light on my MacBook Pro's Caps Lock does not turn on when I use it. However the Caps Lock feature works fine and I don't remember changing any features that would make this occur. I checked the Modifier Keys under system preferences and all defaults are set. This is a 2010 MacBook Pro with OS X Snow Leopard 10.6.7.

It's possible that it's burned out.
I'd try a SMC reset following these instructions:

Bought a Logitech keyboard to. Use with my iPad 2 but doesn't work. What am I doing wrong?

Bought a Logitech keyboard for iPad 2... First of all USB cord doesn't fit and had to order adaptor to connect them but still doesn't work...keyboard came with no directions? How do I make this work?

You're using the Camera Connection Kit. This is designed to connect cameras to your iPad in order to import photos you've taken. However, the Camera Connection Kit, although that was not what it was designed for, has been known to sometimes accept certain simple USB keyboards and even USB headphones. Obviously, your Logitech is of a better quality keyboard and does not work with the CCK, because it wasn't designed to accept anything other than a camera.
Most Bluetooth keyboards, if not all, should work with your iPad. There is the official Apple Keyboard which looks and works great, and connects to an iPad or a Mac using Bluetooth. However, it is a bit on the expensive side ($70). I'm sure there are good alternatives if you need.

USB Headset doesn't work on Mac OSX but does on my WinXP Bootcamp partition

Hi all,
I bought my FIRST Mac 2 days ago and am very excited about the migration. My reality is that I need WinXP for work-related activities and so I successfully installed Bootcamp and both WinXP and Mac OSX is working fine.
My problem is with a brand new Logitech USB Stereo Headset 250. It works just fine on the Windows XP side, but I can't get it to work on the Mac OSX side. Is there something I should be 'turning on' to get the headset to work? Like I said, it just 'worked' when I started up with the WinXP partition but when I restarted in the Mac OSX partition, it doesn't work.
Apologies if this is a simple thing that the veteran Mac crowd is snickering at as they read this, but I truly want to use the Mac OS as much as possible and if I can't get the headset to work on the Mac side it won't be a good thing.
Any suggestions?

Got it (sorry all) - I went into the System Preferences and selected the USB headset from the 'output' tab.

My apple ID works on iPhone 6 but doesn't work on mac

I tried to sync my phone from my mac to get music from my mac to my phone. In the process of that it asked for my apple ID and it didn't work for some reason. I tried several times again and I am positive that it wasn't a typo so i tried to make a new one and the new one didn't work. It works on my phone when I tried it. I am convinced that it's my computer what should I do?

IE uses a different version ''(ActiveX)'' of Flash than other browsers use. You need to install the '''Plugin''' version for Firefox.
1.Download the Flash setup file from here: 
[http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe Adobe Flash - Plugin version]. 
Save it to your Desktop. 
2. Close Firefox using File > Exit 
then check the Task Manager > Processes tab to make sure '''firefox.exe''' is closed, 
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
* On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen).

Caps Lock Light Doesn't Work

Hey There,
I don't know since when this happens but whenever I login to my Arch box, my caps lock light doesn't work so I can't really know if it's on or not unless I try manually. At first I thought that the light is gone but in Windows it workes without any problems.
Any thoughts, suggestions ?

Yeah, it is Xorg 7.3 related, in my investigation I have found that this is a known issue of Xorg 7.3 so upstream is going to give a fix soon, or so I hope.

CAPS LOCK light is not working

Hello dear guys,
Had a problem today - some keyboard keys didn't work properly.
I opened the laptop (Pavilion G6 2241sa) cover and saw that keyboard cable was loose. I reconnected it properly, closed the cover and switched laptop on. Now, all keys are working fine, BUT CAps Lock light is not working well. Key is functioning, but when I press it - the light come on, but as soon as I release the key - the light goes off. Light doesn't stay. Also when the actual function of caps lock is on, when I press any other key the light come on the surface of Caps lock key but it is dim.
I recheched keyboard cable again - all is fine, but Caps lock light doesn't stay on when pressed.
I do practice typing for the last 3 months for few hours each day, so I guess it also affects the life span of my keyboard.
Would appreciate any insights about this Caps Lock light. Many thanks, Vit

Hi there @vitsirius
I understand that the Caps Lock LED is not working, after you had fixed a loose connection to your keyboard.
You may want to walk through this page and see if something may help

Also for your convenience here is the maintenance guide. It is possible when you were working on it one of the of the other connections was loose or became so.

Laptop won't start quickly but power wifi and caps lock light keeps blinking

Hi, it has happened before too but rarely but nowadays it happens on daily purposes.
When I switch on my laptop after leaving it for 8-9 hrs, it won't start up but instead power, wifi and caps lock light keep blinking. I tried removing battery and pressing power button for few minutes but nothing happens. Then i left it like that with lights blinking and after 15 20 minutes it booted. I did same yesterday too. I left it like that it booted after 20 minutes..so My question is "why is this happening? Is it a motherboard issue or is it because of cold moisturous weather here and laptop takes time to get warm up?" Should I show it to HP Service center?

Hi @Nishant5788
Welcome to the HP Support Forums. I see that you are having a problem getting your notebook to boot up normally. As for what is causing the problem the blinking Caps Lock should tell us what is causing the problem as it should be blinking in a pattern. This HP document Computer Does Not Start and LEDs blink has a chart that will tell you what the blink codes mean.
This is most likely a hardware issue and you can give us a call regarding repair options. You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.

Caps lock light not working, can't tell if it was after upgrade or just use

Has anybody else experienced this?: My Powerbook G4's caps lock light doesn't lit anymore.
Was it because of the ugprade from Tiger 10.4.10 to Leopard 10.5.0?
Anybody?

Geez, it's working again... I think there is some type of malfunction when waking it up from sleep.

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.

Wireless keyboard caps lock light not working

Hey, said it all in the title but here's the story...
Got home today and realized that the caps lock LED don't light up anymore. Has anyone else had similar problems? If so, how was your situation rectified?
The keyboard still works fine, don't think its a bad enough problem to have it replaced or be without it for ages. Could see if apple will allow a straight swap at the shop...

Hi Guys
Glad I've just found these posts. Got a new 27" iMac just before Christmas. Greatly relieved that everything worked despite all the reports of cracked screens, etc. BUT - only small problem was the Caps Lock light not always coming on. Rang Apple and got a replacement. Now today I'm having same problems - first the light froze and wouldn't go off. Then it wouldn't come on. I've now tried your advice of switching off the keyboard and taking out the batteries. Works OK now. Hopefuly it'll stay that way. Only thing is - pity Apple couldn't have given me that advice. Reading these posts, there is clearly an ongoing problem with the caps lock light on the wireless keyboard. A problem thats been around for months. Clearly Apple's poilicy, as always, is to admit nothing until it comes up with a fix. Pity that policy appears to extend to not even telling their own employees that there is a problem ...
