It is the backlight that is consuming the bulk of the power, not the color cells. So if you are worried about battery power, you should be using only black and white and turn the backlight down as much as possible with this setting.
The keyboard has functions to raise and lower the brightness; how would I control the backlight separately? (What exactly is the backlight, anyway?) _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
