Unhappy PC does not power-off after shutdown

Hi there.

When i shutdown my notebook it does not power off automatically. Everytime i have to turn it off seperatly with the power-button.

Does somebody know what to change, so that it will work corectly?

What distribution are you using? You may try booting with the kernel argument acpi=off or acpi=force to see if those help. (Some notebooks have buggy acpi that require these)

In Slackware, you have to edit /etc/rc.d/rc.modules to enable APM.

Specifically, uncomment the last line of this section:

#### 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

Oops, sorry that I missed that this was the slack forum. Got to the thread via the Zero-replies search.

If you didn't compile the kernel yourself, then chances are you chose 'bare.i' for the installation and for booting afterwards. 'bare.i' carries only APM support and needs '/sbin/modprobe apm' to be enabled in '/etc'rc.modules' .

The ideal, though, would be to have used 'bareacpi.i' or else recompile your kernel with ACPI support - assuming your hardware supports it, which is the case for almost everything from pIII and over.

I hope this info helps...
