I would like to install SL6 on an Acer travelmate. I know it can be done (cd live boots and installs, all working).
I'm now wondering if anyone has experience in tweaking the system to power saving in particular while on battery (which enterprise service can be switched off).

Does SL has a higher power consumption than other linux distributions?. Are there any data available comparing SL vs windows 7?

I have noticed by example that I get usual twice the time on a windows 7 installation compared to a fresh light arclinux installtion (according to the battery status in the toolbar), although I do no have any real measurements.

I really appreciate your thoughts

Actually SL6 should be very efficient with regard to power use. Check out the following document for information, including ideas for laptops -

A couple of things you can do straight away are

enable laptop mode -
# echo 1 > /proc/sys/vm/laptop_mode

use PowerTop to reduce interrupts waking the CPU from low-power-use states
# powertop #(then follow instructions)

You may need to install PowerTop first.
