Energy management in Linux


Hi everybody!

In Windows XP's (and Vista's) Device Manager, after right click, e.t.c. on a device, there is somewhere an option "Allow Windows to Power Off this device ...". When this option is checked, then every-time windows is turned off, the respected device is also turned off.

I wonder If there is something similar in Linux, Possibly through some configuration file. I looked through the /etc/init.d/ files (especialy one file named halt that is run every time Linux enters runlevel 0 but with no success ... Is this a kernel matter ?
Does gnome include some GUI tools for this job ?

Best wishes!
Vas

Now I'm not an expert on windoes ... but how do you think
windows controls the state of a device when the machine is
powered off? And how would it e.g. power off the network
card if it's connected to the PCI bus on a motherboard with
an ATX power supply?

Are you sure windows does what you seem to be saying
in your post? If so - can you please back that information
up with some reference material, so I can try to understand
how this is meant to work? Thanks.



Cheers,
Tink

The option "Allow Windows to Power Off this device ..." is a power-saving feature for when Windows goes into standby mode or hibernation. It applies to only some devices, such as network cards.

Hi again, and sorry for not replying on time...
I was on a trip these days, for an environmental study and out there -in the forest- there were no Internet

That's exactly the point!
shouldn't the command halt -d -f -i -p -h in halt script of the /etc/init.d/ directory have shut down my network cards ? Well it doesn't

Well, when I turn off my computer, my network devices also turned off, also every other device that supports this feature.
