In regards to the black screen debate: It is true that a black screen LCD setting does not save the energy that an old CRT screen would for reasons mentioned above (the LCD back-light). Further, I believe that there is a very small current applied to induce the black pigmentation and so one could argue that it in fact wastes energy to use black screen settings on an LCD. However, when a black screen setting is used the LCD back-light intensity can be reduced as low as possible without sacrificing the legibility of text (if white text). If it was possible to extinguish the back-light even further, even more energy could be saved (If anyone knows how to do this in windows I would love to know... my laptop only lets me dim the screen to a very low setting but three or four more stops would be even better.) Don't take anyone's word for it, test it yourself: Time your battery duration at under normal preferences, then change your settings, dim the back-light and check duration again. let us know what happens.

But what about the differences between Sleep and Hibernate? Unfortunately WHITE just hurt my eyes.
