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 Frank

Actually SL6 should be very efficient with regard to power use. Check out the following document for information, including ideas for laptops - http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Power_Management_Guide/index.html

A couple of things you can do straight away are

enable laptop mode -

CODE

# echo 1 > /proc/sys/vm/laptop_mode

use PowerTop to reduce interrupts waking the CPU from low-power-use states

CODE

# powertop #(then follow instructions)

You may need to install PowerTop first.
