    For as long as I've owned my powerbook G4 1.5ghz 17-inch, the brightness has been stuck at a single setting.

    Both keyboard and menu changes function, and show that I've changed the brightness, but the brightness doesn't actually change. It even remembers what level I place it on, but obviously it doesn't matter since the brightness of the LCD doesn't actually change.

    I've done all the software updates and repaired my disk and permissions, and I've even tried resetting the PMU and PRAM(?) in the past, but to no avail.

    Now I'm wanting to sell the machine and have to replace the battery (since the display being bright has killed the battery over the years) and wanted to get this sorted as well. Anyone else run into this?

    Haha, I just did another semi-regular search for this problem and found this link on the first page of results. And no answers.

    Just another quick check in case this slipped though the cracks. Has anyone seen anything like this?
