HOW DO I TURN OFF CAPS LOCK?

yes just press the caps lock button again. The light (f there is) will turn back off. 

YOU TELL ME!!!

Push on the "caps lock" button till it becomes unstuck. You may also be able to lever it free if it is stuck.

But if you can't undo it, but you still want to post a question or answer politely, then use the "Shift" key, but in reverse. Hold it down for small case letters, and release it for Capital letters.

In the long run it's usually cheaper to buy a new keyboard than to get it fixed 9unless you're using a laptop).

Make like you're turning caps lock on. Weird, right?

Refer to the enclosed link, if the Cap lock is stuck

Push the Caps Lock button.

Duh.
