If it has a "u" then run "tasksel --install-task laptop" as root. Installing the laptop task will install the following packages: acpi-support hibernate acpi powertop apmd radeontool anacron wireless-tools cpufrequtils nvclock wpasupplicant vbetool acpid pcmciautils toshset bluetooth avahi-autoipd This will set up various laptop friendly utilities including advanced power management support. You can research what each package on this list does, of course, and pick and choose them on your own individually. Good luck! -- Chris
