I disagree with you here: this doesn't make sense for the computer, but it make sense for the user.

If the user stays too long with doing anything the screen will idle to black and then the backlight will be disabled: it make sense to have an idle screen as quite often the user will move the mouse to re-activate it.

Should the idle screen be white or black?
There's a power usage reason for it to be white for LCD, but there's also a 'do not distract the user' reason to use black as when the backlight will be disabled the user won't notice an annoying white to black flickering.

As soon as I lock the screen, the background light should turn dark.
Besides, my netbook uses a LED backlight so I don't have to care about dying cathodes. :-)
