Did anything spill on your mac? Try blowing some spray air to clean in between the keys and keyboard. If that doesn't work, you can pop off the keys individually to see whats going on, but be very careful or take it to an apple store.
Unlock the Caps on Computers
The All-Caps or "Caps Lock" function causes all letters to appear as capital letters when typing into word processing documents, emails or other files.
This is convenient when needing to type numerous capital letters or All-Caps phrases, as you do not have to hold down the "Shift" button with one finger as you type the words.
When All-Caps is stuck and does not respond to the "Caps Lock" keyboard button, a simple procedure overrides and shuts down the function.
Open a word processing program.
Press the "Caps Lock" button located on the left side of the keyboard to turn Caps Lock off. Type inside the document.
If lower case letters appear in the document, Caps are successfully unlocked.
Proceed if the text is in All-Caps.
Hold down "Shift" on the keyboard. Press the letter "P."
A lower case "p" appears in the document. Release the "Shift" button.
Type the phrase "rint" directly after the lower case "P." The word "pRINT" is now in the document, and the document cursor is after the phrase's "T."
Press "Enter" on the keyboard.
The cursor goes down one line and "pRINT" becomes "Print." The "Caps Lock" function is turned off.
Restart the computer to save the setting.
Enable the Caps Lock Key
The "Caps Lock" key is loved by some and disliked by others.
The key turns all letters into capitals as you type.
While this feature is useful in some situations, a more common occurrence is that the key is accidentally hit and all the text typed is capitalized.
The person typing must then delete the capitalized type and rehit the key to turn off "Caps Lock."
If the "Caps Lock" key needs to be enabled, it indicates that someone has disabled or remapped the key.
If a user wanted to, the "Caps Lock" key can be disabled and enabled through the registry or remapped through the control panels.
Updating the registry for the keyboard will enable the "Caps Lock" key.
Open the Notepad program.
Type the following:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=-
Select "Save As" from the "File" drop down menu.
Navigate to the computer desktop as the save file location and choose "All Files" from the "Save as type:" drop-down menu at the bottom of the Save As window.
Type "enable.reg" without quotes in the "File name:" field and click "Save."
Minimize all open windows to view the desktop.
Double-click on the "enable.reg" file. A box will pop up asking if you are sure you want to run the file. Select "Run" or "Yes" and then click "Yes" for the Registry Editor warning.
Reboot the computer. The registry will be updated and the "Caps Lock" key will be enabled.
Manually Update the Registry
Click the "Start" menu, type "regedit" without the quotes and press "Enter." In older versions of Windows, Click the "Start" menu, select "Run," type "regedit" without the quotes and press "Enter." This will launch the Registry Editor.
Navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout" to view the settings.
Right click on the "Scancode Map" setting and choose "Delete." Click "Yes" to confirm the deletion.
Reboot the computer. The registry will be updated and the "Caps Lock" key will be enabled.

Select "Yes" to install the registry file.
