Machine to power off automatically.

Machine to power off automatically.

[Lars Bungum]

I can't get my machine to turn itself off automatically (when I tell it
to do so in KDE), it just hangs saying "Power Down".  Is there some
option I have to enable in order to get this working?  Looked at the
APM/ACPI sections, but felt that was more related to laptops and
batteries, etc.  My BIOS was too old for ACPI, anyway.

Hi,
You don't say which distro or kernel you are using, which may help.
For what it is worth I had this problem a while ago. My Redhat box died and the 
only CD I had was debian. The new debian box (kernel2.4.18) would not power down 
automatically. I just loaded the apm module and things then worked as expected.

regards,

John Kelly

John,

my system is based on RH9, with the kde-redhat project inside using
apt-rpm.  However as shutting the machine off works with the exact same
configuration only booting a different kernel (the 2.4.18 shipped with
RH) I suspect some option/module must be set in the kernel to get this
working.  The "apm" module is loaded, and the "apmd" daemon from the
RedHat system is started and runs without error.

My problem is that I don't really know what is supposed to make this
particular feature work.  Is it apm?  When I read the docs about
APM/ACPI it seemd all to be about battieries and other laptop-related
matters, and my machine is just a standing desktop.  So what software is
it that is supposed to make this work?

APM = Advanced Power Managment
ACPI = Advanced Configuration and Power Interface

It would be one of these options that would handle shutting down the 
power on your computer, most likely APM if you have an older BIOS.  It 
does also take care of batteries on laptops, but it is Power Managment 
in general, not just batteries that it handles.

As to fixing your problem, you did say the APM module is loaded & apmd 
is running without errors, so my best guess is that your APM module is 
missing some option required for it to work right on your machine.  Look 
through your kernel config and check a couple options that you think 
might have to do with this, such as "CONFIG_APM_REAL_MODE_POWER_OFF":

	Use real mode APM BIOS call to power off

	Use real mode APM BIOS calls to switch off the computer. This is 

	a work-around for a number of buggy BIOSes. Switch this option
	on if your computer crashes instead of powering off properly.

HTH,

Con, 

thanks a bunch for your illuminating clarifications.  When I altered
some options under APM, it worked.  (My BIOS was too old for ACPI).  As
I enabled more functions, I can't really know what the trick was, but I
suspect that it actually was compiling apm directly into the kernel
instead of loading it as a module.  The
"CONFIG_APM_REAL_MODE_POWER_OFF": was enabled all the time.

BTW: Another "strange" thing I saw, is that my isapnp Soundblaster
stopped working when I compiled a kernel with pnp BIOS.  Something to
try if this is a problem, I guess.
