What Does The On/off Button Do, can I do it from command line Options

[Chero]

As the title says,

Can I do the same from command line as if I'd press the power button ?

I have a C1000 with a power button that lets me down every now and then, causing the Z to freeze. It's not debian related, it happens in pdaXrom, Angstrom, debian eabi and titchy. I haven't tried the sharp-rom, but I suppose it would be the same.

I see the screen dropping to a "console" on my C3100, then I see it "stopping tasks" before power turns off. When I use apm --suspend it doesn't do that.
Does anybody know what command/script I have to look for ?

Thanks,
Chero.

What works on desktops is:
shutdown -h now
You can try that and see what happens.

That also works on my zaurus, but I don't want to shutdown, I want to suspend.

Thanks for the effort anyway,

apparently

apm --suspend

seems to do the job.

apparently there's apm --standby too, i haven't tried.

So do you mean it is a hardware failure?

It's very straightforward to map the suspend command to a shortcut key to make up for the misbahaving power key. Perhaps modifying the kernel keymap and xmodmap will fix it once and for all?

apm --suspend works as advertised. -- standby gives me "invalid argument". apm --help lists it as an option, though.

Ok, but first I have to know what the suspend command is.

Check this :
Use the on/off button to suspend, then resume using it again or using the home button. Check dmesg :
stopping tasks...done
restarting tasks...done

Then use apm -s to suspend and resume using the on/off or the home button. Check dmesg :
restarting tasks ... done.

But there is no stopping tasks.
This brings me to my initial question : what does the on/off button do and how can I do it from command line ?

Just a wild guess: What does the /etc/sysconfig/keyboard/kernel.map in your pdaXii setup say about the Power AND the Home buttons?

[Chero]

I've done a few tests and it seems that apm --suspend does add "stopping tasks ... done" to dmesg, so I guess I'll have to do some more testing and see where it leads me ... .

Thanks for all the answers.

I just wonder if it is possible to remap the Power/Home key to something else, without even knowing the exact command, so as to make the new key function in the same way as Power/Home key.

i don't know if it is related to this thread, but i notice some battery draining while the zaurus is suspended.
am i the only one ? perhaps my zaurus battery is beginning to be a little old, i've never changed it since i've bought my C3000

Can't tell yet.
The day before yesterday my 3200 was busy compiling things busily without any external power source. I checked after three hours of compilation and the bettery went down from 9x% to 50%.
