I am so jealous of that low power consumption. I traded in an X40 (~12W) for an X61 (~15W). I had no idea the X31 was so efficient. It's possible to run the an X61s laptop with 8-9 watts. See my blog posting on the subject. Since it was written, I've been able to run my laptop in "airplane mode" (wireless, USB, etc. disabled, screen brightness at 40%, my inbox loaded in mutt, and reading e-mail) down to 8.7 Watts as measured by the powertop tool. This was with a 2.6.25 kernel and Ubuntu Gutsy, and with known power-wasters stopped or killed (i.e., firefox, gnome-multiload-applet, gnome-terminal blinking cursors disabled, etc.). Presumably with newer distro's some of the things that I had to do manually (i.e., unload iwl4965 if it is not in use, kill stupid GNOME applets that weren't written with power usage in mind, etc.) won't be needed any more. But its certainly possible to make an X61s only use 9 watts.
