    Then, edit (vi) the file


    and there you find a section like

    #### APM support ###
    # APM is a BIOS specification for saving power using several different
    # techniques. This is mostly useful for battery powered laptops.
    #/sbin/modprobe apm
    Just remove the #-sign in front of the line
    #/sbin/modprobe apm
    this worked for me, btw i use the command poweroff to shutdown my computer

    shutdown wont power off

    It is possible to use this command in Slackware:

    This will cause the system to 'KILL' (stop) all of the processes and it will shut down and restart. I hope this helps; I know in version 3.5 of Slackware (the version I am running), it works to restart the system. I had found trouble with the command:

    because it seems to present a list of options to me instead ofd shutting down the system.

    try the
    shutdown -r
    to restart, and
    shutdown -h
    to halt the system.

    i found in slackware 10.0, that reboot would restart automatically, but halt wouldn't.

    so i recompiled apm support, wouldn't work, recompiled with acpi, didn't work. While I had ACPI, i decided to type "dmesg" and it said something about acpi not being on and that i need to append "acpi=force" to my LILO. I did that and my computer has been shutdowning by itself EVER SINCE.

    That's why I asked you to do "dmesg | grep acpi"

    Last time I used APM was in Slack 9.1, but I found it easiest to make sure APM was compiled in, then put modprobe apm into my rc.local.

    If i modprobe apm and then shutdown -h 0, it shutsdown normally

    but after it has unmounted and done all its other stuff, i get a segmentation fault, as if there is a problem with apm?

    Anyway, it still dosnt power down, no matter what command i give it.

    im thinking maybe the kernel i have wont support apm, or acpi or just dosnt have it compiled, any ideas on how to check or change this?

    THanks for the support!
