Some observations on my A470. The camera, although it has no optical viewfinder, does support "sleep mode", which can be assigned to the print button. The manually activated sleep mode is equal to the power save mode.
When the camera enters sleep mode, does the keyboard task still run?  (and hence the CHDK scripting engine!)

Can I assume from your note that a click("print")  would activate sleep mode if its assigned to the print button?

The notes.txt file for that camera say its uses DryOS.   Does that suggest the "sleep mode" might be available in most cameras ?

Mode                        Current draw
Play                        125mA
Play, backlight off          55mA
Rec, "P", HI ISO            390mA
Rec, "P"  AUTO ISO          350mA
    +backlight off          275mA
Rec mode, sleep              50mA
Movie mode, 640x480 20fps   460mA
            320x240 30fps   425mA

Numbers look about what I would expect and I believe are pretty consistent with my test results.

Yes, I can even enter and use the CHDK menu (the buttons are still masked by CHDK, so the camera continues to "sleep").

It should, although I haven't tested it. You can try it on your G10, I guess.

The "on demand" version is probably not, the "power save" version is. It seems that this functionality is not available as a single event procedure, so it requires button presses :(
I have tried experimenting with various event procedures, but using them is complicated (you can easily crash the camera or the display will stay dark :)), and the drop in current draw is not too significant...
Play + backlight off seems to be the closest to sleep mode. Prevention of lens retraction is useful here.

I can confirm this works on d10, and should probably work on any camera that lets you assign sleep to print.
Don't forget what the H stands for.

So what this means is that camera that don't allow their display to be turned off via the display button but that can assign sleep to the print button get pretty much the same power savings as cams that can turn the display off via the display button.

... some dinosaur bones from mid 2008
Seems like all the power savings ideas have been around for a while now.  But then I really only started this thread to actually measure and document how much each trick saves.

i would gladly repeat your test with my (working :() cameras.
is there a place to post the results? or is it here?

Updated script to also allow using "sleep mode" via the shortcut key as suggested by srsa_4c here : http://chdk.setepontos.com/index.php?topic=9049.msg97241#msg97241

Here are my results for the A530. Tried to follow waterwingz's format. Unfortunatelly I have no idea how to use tabs here so I used Courier. SX30 is to come in a few days (I hope), A590 and SX260 SX240 when I can borrow them.

Camera: Canon PS A530
Batteries: 2xAA Sanyo eneloop 2000mAh, 1900mAh minimal capacity (HR-3UTG: 1st generation eneloop, about 4+ yrs old)
Charger: Voltcraft IPC-1L

Test Suite One
Shot Interval :  4 seconds
Trial   Setup                                                                 Results
1       no optimization                                                       2639 shots over 03:14 hours

3       display off                                                           4411 shots over 05:18 hours

2       backlight off between shots                                           248 shots over 04:07 hours
5       backlight off between shots, screen off via power save after 10 sec   252 shots over 04:11 hours
3       backlight off, idle in playback mode                                  682 shots over 11:21 hours
4       display off                                                           1021 shots over 17:00 hours


ok, i cant get the formatting right. still, i hope that the data is self-explanatory.
