What was it ? System, like turning them on and just going away? With half that was about it, doing no more than going to a DOS or shell prompt or a boot loader menu. No power saving features were enabled beyond a bash or Norton commander screen blanker. Some were running a GUI, but not with anything substantial happening, no Gimping, OO, kernel compilations, or DVDs or music downloaded, burned or played. All those systems except the now dead T18 remain (multi) bootable. I'm writing this from the (space heater) Foxconn. I didn't tabulate installed memory, so what you see for the AI7 comparison needs an estimated adjustment for the Celeron config having half the RAM of the Prescott config. The Dell I originally did just to a DOS prompt, but the original result didn't meet my expectation, and I rebooted it into WinXP and loaded Firefox to a passive page, then just left it, only to find a statistically insignificant difference. None have or need active video cooling. > That's an interesting measurement in any case :) I figured some would reach such a conclusion. My main points were fairly recent stuff gobbles power compared to pretty old yet still servicable stuff, and 80+ genuinely saves. -- "Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up."
