1. Make sure you have support for laptop mode in your kernel. If you're running 2.6.6 or later you should be fine. The laptop mode sysctl is located in /proc/sys/vm/laptop_mode 2. Please run post-install after installing this package since my acpid package includes some config files that will interfear with laptop-mode-tools otherwise. Following files will be removed. /etc/acpi/battery.sh /etc/acpi/events/battery.conf Those are all included in my own acpid package. If you installed acpid from /unmaintained you should look at its footprint and see for yourself. Mattias
