Hello, well I just purchased a brand new powerbook, a 15 inch, and i know that it should have ALS for the keyboard, the thing is, that the ALS won't automatically adjust the illumintation for my keyboard, I think it used to, until I manually pressed the F10 button (to increase the illumintation manually) and ever since then it stopped working!!! I get a light and all but it won't adjust automatically, I've tried going into the system preferences and I entered the keyboard preference and I turned the option off and then back on for illumination, and then I did the same thing for the display, btu it still won't work...SOMEONE PLEASE HELP ME OUT HERE!!! I'm so lost...
