Re: [lug:18005] Which Distro to Choose...

You could try a lighter desktop environment such as XFCE or LXDE,
depending on how minimalist you want to go. Or instead you could try
some tweaks and add-ons. There is a discussion here:
http://ubuntuforums.org/showthread.php?t=2040280

and here: http://askubuntu.com/questions/152453/how-to-reduce-the-fan-noise-and-how-to-increase-battery-life

I don't own a laptop, sorry, for not offering more. Report back if you
find a good solution because it will help others.

Windows uses a Technology called cpu or core parking which halts down cores that are not in use, this helps in power management, but linux lags it, however linux uses methods called ACPI to control power consumption which is different than that of windows.

The article really just discusses ACPI, which has been an industry-wide power management since somewhere around Win95.

Linux has several different management schemes, although I don't remember the names of all of them. However, there is:
http://wiki.debian.org/HowTo/CpuFrequencyScaling
It's installed already on Debian; apologies if it isn't as straight-forward on Ubuntu

There's also Laptop Mode Tools--although I don't know if they're up-to-date:
http://samwel.tk/laptop_mode/laptop_mode
http://www.ubuntugeek.com/laptop-mode-tools-laptop-power-saving-package-for-linux-systems.html

While I was digging those up, I came across this link, which looks good and thorough:
http://www.thinkwiki.org/wiki/How_to_reduce_power_consumption

on ubuntu software center look for powertop, ibam, and laptop mode tools. install them and reboot . report back and let us know results.
