Following situation, not too unusual for me:

Battery is low, I can't charge, but I won't use the device anyway for some time. (Wonder when this happens? Well, I go to a cinema. Or I am in a fancy restaurant where cell phones are considered inappropriate.)

I want it to work afterwards, though, and I don't want to switch it off. So (depending on which device I have with me) I go through a couple of steps to switch off what I think consumes battery. I might choose offline mode, silent profile, I might want to close all running applications just in case one of them misbehaves, I shut down GPS if there is any on the device... and then lock the screen.

Now wouldn't it be nice if I could do all of this with one single click?
A "deep sleep"-application that would add one more button to where the profiles and presence settings are. Press it and all is done.

The application should have a configuration part, of course, so I can choose which parts of the device go down when I activate this mode. Someone might want to keep applications running, another user may want to keep GPS or wifi... just a list of things with checkboxes.

Is this already in the making somewhere (seems so obvious to me) or do I have to politely ask for it?

I was thinking this too on the train, whilst the N900 was complaining of low battery and I was frantically trying to reduce screen brightness, decrease volumes, disable connections, etc. You beat me to it.

I got it: Pull the battery.

OK, a button in the status area that switches the profile to silent, switches the device to offline mode, and locks the device would be v.easy to do; even for me with my bad programming skills.

GPS... I believe you must close the application using it to stop it (AFAIK ), and closing all the apps on the screen... Possible, I guess - wmctrl gets a list, at least but you'd have to kill -9 'em to make sure that they'd all gone - we don't need no confirmation screens hanging around.

I don't think so, but making one should be relatively simple. Just about everything in the device is controllable via DBUS and programs should respond to POSIX signals.

Making it all configurable and nice UI is going to be plenty of work, but it's not hard, read up on some python and start experimenting

Wasn't there such a thing as "Soft-Poweroff" on the N900 that could be enabled by modifying some file? Or was this only on N8x0?

Here's an extremely crude hack:

Code:
#! /bin/sh

dbus-send --session --dest=com.nokia.profiled --type=method_call /com/nokia/profiled com.nokia.profiled.set_profile string:"silent"
dbus-send --system --dest=com.nokia.mce --type=method_call /com/nokia/mce/request com.nokia.mce.request.req_device_mode_change string:"offline"
wmctrl -l -p | grep -v hildon-home | grep -v hildon-status-menu | grep -v desktop | awk '{print $3}' | sort | uniq | while read p; do kill -9 $p; done
dbus-send --system --dest=com.nokia.mce --type=method_call /com/nokia/mce/request com.nokia.mce.request.req_tklock_mode_change string:"locked"
Requires wmctrl. Will set the profile into silent, put the device into offline mode, proceed to kill -9 apps with a visible window, and then lock the screen and keys.

I wgetted it from http://qole.org/repository/pool/main...07-6_armel.deb, used dpkg to install, got an error saying libxmu6 was missing; apt-get -f install worked a treat.

Oh, BTW, I'd recommend not running that script from an X Terminal. Make a desktop file or something.

Hijack..
Is there a way to turn off all sounds?
I thought Silent profile meant silent, but I find alarms, games etc all happily create sounds. I was hoping for a way to use it in confidence that not a peep will be heard from it.

Thanks
Sorry for the hijack, I thought it was a little related.

Faheem: works beautifully
Benny: thanks for the idea, the best way to save power for those like me who use it as a tablet, more than like a phone
