shutdown problem

hi,

i am using mandrake 10.1 official. when i shutdown it does not turn off the cpu until i switch off the unit. what could be the problem?

advice would be appreciated.

thank you

Hi

It could be something to do with APM or ACPI.

Try:

# modprobe apm

and try shutting down. If that works add it to /etc/modules.conf If it doesn't try adding 'acpi=force' to the kernel parameters on boot, and add it to the configuration file for your bootloader if it works.

hi,

how would i do the second option as the first one did not work?

thank you

Hi

What happened when you tried the first one? Did it produce any errors?

I haven't used Mandrake in a while, but when booting, does it say something about entering kernel parameters? (you might need to press ESC or possibly F2 or something). When you get a prompt, type:

Code:

<kernel name> (eg. linux) acpi=force

It seems that by default Mandrake uses LILO as the bootloader, in which case the config file is /etc/lilo.conf. To make the change permanent you need to add the line

Code:

append="acpi=force"

to the section describing the kernel image, eg.

Code:

image = /2035-1542-sb16

root = /dev/hda6

label = linux

read-only

append="acpi-force"

You'll then need to run /sbin/liloconfig (as root) to write it to the MBR.

Hope this helps.
