Probably two different things...My indigo 366 iBook has a slight orange tint when it is turned on that gradually fades but seems present a bit. I also tried to change brigtness and realize that the brightness control does not function. Any ideas on either or both...maybe backlight on screen? ...maybe ppwer management unit needs resetting (or so I have read)? and is there another way to adjust brightness in OS9...I can't find one..Thanks
