Last night I received a couple of big stings. I'd like to figure out how to avoid this. I've heard of the trick of touching a grounded metal object, and also to touch the computer casing before touching the rest of the computer, but it hasn't been working.
Is there a chance that there is a problem with the built-in keyboard? I can see more metal parts beneath the keys than I see on most peripheral keyboards, and it makes me wonder.
