keyboard? It won't snap in!? I have had to remove the caps lock key from my laptop keyboard, but I can't reattach it. I was easily able to snap in all of the other keys I pulled off (e.g. various numbers, shift, control, etc.), but the caps lock key has a little metal bar on the back of it and I can see where that slots in, but when I push on the key it just won't snap in! Any help would be much appreciated.
