Some of you read the thread-- I just bought a second 15" PowerBook. It's exactly the same as the one I already had, except for the amount of RAM. Just did a fresh install of Leopard on the one I just bought and noticed the keyboard isn't lighting. I looked on my main PB and the illumination settings are in the keyboard & mouse settings. On the second PB those settings aren't showing in the keyboard options. I found an article on Apple's site that says the F8, F9, and F10 keys have the illumination function icons printed on them when the keyboard is a backlit keyboard. The second PB has these keys. I've tried resetting the PRAM and VRAM but I still don't have the options. Any ideas?
