edit: it works, i just tried it out on my computer
34) When I shutdown my computer using halt or shutdown -h it does not turn off automatically. How do I change that?
Most newer machines can power off automatically when you shut them down. This is typically accomplished through APM (Advanced Power Management). By default Slackware does not load the apm kernel module, and this prevents the machine from shutting down through APM. To enable the apm kernel module you simply have to edit the file /etc/rc.d/rc.modules and make sure the /sbin/modprobe apm line is uncommented (by default the line is commented out by being prefixed with a '#' - remove the # and save the file). If you enable the apm module in this way then the next time you reboot your machine should be able to power down when you issue the halt or shutdown -h now or similar commands (or shut down through your GUI).
