"The reason for white, fyi, is that LCD screens are ON when they are black, and off when then are white." So does that mean I should set my PowerBook screen to go white to conserve the battery? Odd that I've seen no other web site advocate this. Why?

Because of the way LCDs work, you can make 'on' either black or white. Computers typically make it black (the screen is black when your LCD is off).

You could just look at the power consumption to find out, but I doubt that turning pixels on or off takes much power at all. The thing likely taking up 99% of the power is the backlight, not the pixels, so turning the backlight off (or putting it on display sleep) would work better.

And of course, the thing that needs replacing on LCDs is most commonly the backlight.
