Average power consumption in S3?

[Moritz Muehlenhoff]

Hi,
I'm using an IBM Thinkpad X31. With stock 2.6.11 and the additional
radeontool to power-off the backlight in suspend, S3 works very well
and reliable. During S3 I've measured a power consumption of 1400
to 1500 mWh (using 512 megabytes of RAM). Is there still room for
optimization? What's the typical amount of energy required for suspend-
to-ram? From friends using iBooks with MacOS X I've heard that they
left the notebook in suspend when leaving for a week and could still
use it after return.

Cheers,
        Moritz
