The title pretty much sums up my problem. I can type fine, but holding down the key doesn't repeat, including the arrow keys which is super-annoying.
"Filter Keys" in the Ease of access center is not turned on, so that's not the problem.
UPDATE Also, the numeric keypad on the right is not working at all -- not just that it won't repeat, but there is no response at all to the numbers, the enter key, the numlk key. The purple Fn+NumLk which usually opens the calc program doesn't work. It's like it's totally disconnected.
