This is provoked by a blog when I was searching for an answer: why my keyboard is locked to capital letter when caps-lock is not pressed. One of the blogger said something like this: find a hammer and smash the keyboard, you will get lower case. How graphic even it is not helpful.
I wish they made keyboards with no caps lock full stop. In your case, it is locked to it, in my case, I am always catching it with my finger in error. IT'S A BLOOMIN' NUISANCE WHICHEVER WAY!!! See what I mean? I love your image, it is beautifully done and very amusing too!
