Press the Caps Lock key again. If you turned on Caps Lock by pressing the Caps Lock key (accidentally or otherwise), pressing it a second time will turn off Caps Lock if the key itself is functioning properly. This can be annoying given Caps Lock's proximity to the ⇧ Shift and Tab ↹ keys, so you may want to disable it entirely. This is possible on Windows and Mac computers. Clean the stuck key. If the Caps Lock button doesn't turn off when you press it a second time, it might be stuck in a lowered position. Clean it with a can of compressed air, or wipe it carefully with a cotton swab dipped in rubbing alcohol. Be careful when doing this, as harming the key or its underlying components may void your computer's warranty. Restart your computer. Sometimes restarting your computer will be enough to cancel out a stuck or broken Caps Lock key.
