Power Management with FC5 on ThinkPad R40

I had some problem with the power management. The charging didn't engage after having it unplugged but it charged when shutdown and unplugged. Running on AC was fine all along. However, problem solved by the advise from this german fellow and installing the laptop mode tools. I manually installed the scripts /etc/acpi/battery.sh, /etc/acpi/lid.sh, /etc/acpi/events/lid, /etc/acpi/events/ac_adapter at the former link and then grabbed the rpm from the latter.
