Automatic Power-Off of an SMP System
Support knowledgebase (swiegra_SMP_power-off)
Applies to
SuSE Linux: Version 8.0
Situation
You use a multi-processor system and you would like your computer to turn off
automatically when you shut it down.
Procedure
Use the kernel parameter 'apm=power-off'.
Insert this parameter in the correspondening append line of LILO's configuration
file (/etc/lilo.conf).
To do this, proceed as follows:
-
Open the file /etc/lilo.conf with an editor of your choice, e.g.:
mcedit /etc/lilo.conf
-
Search for the following section (at the line "root", your root partition will be displayed):
image = /boot/vmlinuz
label = linux
root = /dev/hdxx
initrd = /boot/initrd
append = "acpismp=force"
and insert the above mentioned parameter in the append line. The result should look like this:
image = /boot/vmlinuz
label = linux
root = /dev/hdxx
initrd = /boot/initrd
append = "acpismp=force apm=power-off"
-
Save the file (F2) and quit the editor (F10). Now proceed to reinstall LILO:
lilo
-
After rebooting your computer, it should turn off automatically at shutdown.
