Someone recently asked why their computer doesn't turn off automatically when they issue a shutdown command. In my case, it was because I installed SuSE with failsafe settings, and during installation when the SuSE installer created the /etc/lilo.conf file it added the failsafe settings to the default kernel, /boot/vmlinuz this is what that section of the /etc/lilo.conf file looked like: image = /boot/vmlinuz label = linux root = /dev/hda3 vga = 791 initrd = /boot/initrd append = " ide=nodma apm=off acpi=off hdd=ide-scsi" I believe that the automatic turning off of the computer is handled by APM (Advanced Power Management) or ACPI (Advanced Configuration and Power Interface). Although APM is enabled in my BIOS, it was turned off in the kernel by the "apm=off" kernel boot parameter, so when my computer reached runlevel 0 (halt) it did not turn off automatically. I edited my /etc/lilo.conf file and removed the parameters "ide=nodma apm=off acpi=off" from the append line of the default kernel, and my machine now automatically turns off when it reaches runlevel 0. I believe the "apm" parameter was responsible for this change, but it may have been the "acpi" parameter or both (I'm too new to Linux to know). Steve D
