> There could be other factors except CPU. For example, GPU, screen =
backlight, disks, etc. Without having proper video driver for AMD GPUs =
it is difficult to predict its power consumption. Also you may look on =
this page: http://wiki.freebsd.org/TuningPowerConsumption . It was =
written some time ago and mostly for Intel, but hopefully better then =
nothing. Unluckily I have no experience with AMD laptops.
Actually I think it's a matter of GPU. On Linux, I can use the =
proprietary drivers. On (PC|Free)BSD, I am using the VESA XOrg driver.
The link you gave me allowed me, some time ago, to lower my netbook =
power consumption, going even lower than Linux.
The machine is compiling the patched kernel now. I will try to reboot it =
as soon as finished.
