Hi, I forget yesterday to share these two scripts: http://www.alogreentechnologies.com/freebsd/checkbattery checks the battery status of an X220 and shuts the machine down when the battery falls to 2% or below. The status is checked every minute. It calls the following script to shut the machine down: http://www.alogreentechnologies.com/freebsd/poweroff You must run the first script as root to enable it to power the machine off at the end. I found that the battery life of my machine was higher using a simple window manager like blackbox compared to things like GNOME or KDE. This might depend on the usage pattern. Erich
