I've searched the boards on this, and haven't found a solution or a similar problem yet. My USB keyboard that came with the computer was working fine for about a year, but lately the left shift key will not capitalize certain letters--first t and then over time y, u, i, o, p--on the top row of letters. The other shift key works but it makes any serious typing cumbersome, and the left shift key is fine on all the other letters. I've unplugged, restarted, checked speech preferences, etc. with no luck. It does not appear to be correlated with an new applications either. Anything else I can try before I have to buy a new keyboard?
