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.
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 was a bit disappointed with the battery life of crunchbang out of the gate. I installed laptop-mode-tools but that did not do much. So I hacked together a little script that will enable some power saving tweaks when on battery power, and default to best performance while on AC. It should work on most setups, but YMMV.

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'm wondering if I'm missing anything, if theres any other way to prolong battery life- make sure laptop mode is on (laptop-mode-tools) and configured- make sure cpu scaling is active, with a scheduler like conservative or ondemand- perform all or most of the powertop suggestions for intel processors- for sandybridge intel chips, set rc6 in the kernel flags (if its stable for you)- disab
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
Hi all,I've noticed, than dispite I've set ENABLE_LAPTOP_MODE_ON_AC variable in /etc/laptop-mode/laptop-mode.conf on 1, when I'm switching on my laptop being on AC power, laptop-mode is not actually activated.So, if I check /proc/sys/vm/laptop-mode, I'll get 0 value.
