Hey! Glad I was able to help! I was kinda wondering if I was the only one with this problem.I think the reason we only had the problem on battery power is because laptop mode tools itself is set by default to run only when on battery power.

I have read (I think) all of the relevant wiki pages. (But I could be wrong - they seem to criss-cross in various ways and I go in circles!) I've also googled what I can, read the man pages and been through all the config files I could find.What I planned to do: do power management with acpid and laptop-mode-tools with pm-utils, which I believed complemented the others.
I configured my installation of Laptop Mode Tools to enable SATA powersave at all times, because the fan runs at maximum speed without it on. When I unplug the power connector, it works great--SATA powersave is on (as reported by powertop). But when the laptop is plugged in, SATA powersave turns off, even though I (see config file below) explicitly told it to stay on! What am I d
Laptop mode tools is just a front end. I am fairly sure it is probably using acpid to accomplish it, so yes, you should be able to do it. I'm not sure how since I use laptop-mode-tools and haven't bothered to figure it out myself.

Laptop Mode Tools is a laptop power saving package for Linux systems. It allows you to extend the battery life of your laptop, in several ways. It is the primary way to enable the Laptop Mode feature of the Linux kernel, which lets your hard drive spin down.

What else would you recommend for power management on laptops aside from laptop-mode-tools and cpufrequtils?These five things already mentioned should be plenty: laptop mode tools, cpu frequency scaling, acpid, pm-utils, and kernel flags.
I have pm-utils and laptop-mode-tools on the same system, but I use pm-utils just for suspend and hibernate. I am fairly sure they are both just front ends for the same back end programs that actually manipulate power settings. You can use both, but I don't see how it would really benefit you. If you are seeing a power savings by using both, it is likely just because you are
