It was definitely defaulted to "true", and at one point even reset itself back to that.

However it is maintaining the "false" setting since I reselected that, so far at least.

This device has been glitchy since I got it, I was hoping it was software-glitchy but perhaps not.

I have mine set like this:
KsmAutoselectafter=10
ksmAutoselectoption=start_koreader

But if you didn't want to "Autoselect" at all you could change it to this:

#KsmAutoselectafter=20
#ksmAutoselectoption=start_nickel

So in the first case you autostart KoReader - but isn't the second case the default behavior that will auto-start the factory software, which I am hoping to avoid doing ever?

I guess autostartign KoReader would solve the problem, if I can make it wait longer than 20 seconds to do so on the off chance that I have something to do in KSM.

Hmm... I think you may not understand how this works.

You're right, I did not.

First with an e-Ink display, no power is used (by the display) while an unchanging image is displayed. So, having any image up makes no difference, a solid black or white image or an intricate grayscale masterpiece - no power is used to maintain the image. No CPU cycles, either.

As I mentioned in another post, my old Kindle Keyboard used to run the battery down a lot faster in sleep mode than it would when I completely shut it off. I just figured that was due to some trickle of power being used to maintain or refresh the image. Apparently not, LOL! Must have been something else.

With most "sleep"/standby functions, the CPU is put into a very low power mode that is just waiting to be called back to work. For some devices, other similar steps are taken to safely suspend critical background processes. For Koreader the WiFi transceiver turned off, as well. Most of the suspend function is a very low level hardware function supplied by the chip manufacturer, the low level routines to activate the function are included in Kobo's firmware. Both Koreader and Nickel have routines that prepare the device before they call the hardware function.

Well, yes, but I would think the un-suspend/wakeup would turn everything - including WiFi - back on, not?

Powering off is intended to be just that, there is a Poweroff menu option provided by KSM and also in Sergey's launcher, otherwise it is achieved by holding the "Power Switch" for 20sec or so. A quick flick of the power switch should be the hardware way to call the suspend function. (And how you return from it.) For your one non-sliding button H2O, it might be a quick press of the button, to suspend and hold down for 20sec. to poweroff.

I understand that - but it appears that in KoReader it IS actually going to sleep without refreshing the screen so that I know it has done so. Or is it? I would have expected more lag when I pick it up and go back to reading in that case.

In any case, my preference is for it to go to sleep after a reasonable amount of time, which I define as about 5 minutes, AND LET ME KNOW IT HAS DONE SO in some fashion - under the factory software I had it set so that it showed "sleeping" in text in the lower left corner.

Then after a slightly longer period of time - which I have decided is about an additional 10 minutes or so - it will automatically power down.

This would need to happen in KoReader and I don't know how to make it do that yet, IF it can be done.

I need it to do this because it is not unusual for me to fall asleep with the e-reader still on. My Kindle Keyboard had way more battery life when it was shut down as opposed to just sleeping; so I was really glad to see that there was an autoshutdown feature in the factory software, to extend battery life.

I have been assuming that the same would be true for the Kobo - but maybe it is not the same issue, if its not the screen draining the battery, and especially if the factory software has been bypassed via KSM etc.

I had thought that KSM was like a shell, with other software running inside it and somewhat under its control - which is not the case. So - for the sleep and autoshut down features, I need to figure out how to make that happen inside KoReader, if it is even possible.

Koreader has a sleep/suspend function and you can have it display your own image of choice (current discussion is working on how to have it provide a randomly selected image from a number in a folder, a different one each time the sleep function is activated, by a power switch flick). Most of us probably just have it set to use the current book's cover image. There is a way to set the image to be used when there is no cover or when koreader doesn't find one or when you don't want the cover used.

I had it set to use the book cover, but it has never ever displayed that. I really don't think it is sleeping, ever. It used more than 25% of the battery since last night. I left it with a file open in KoReader over night. It never displayed the book cover, it just continued to display the last page read.

I cannot find anywhere inside KoReader to change or set how long it should sit idle before it sleeps, let alone how to make it autopower down, if it will even do that. So I'm rather at a loss. This bodes ill for battery life given that I routinely fall asleep while reading, during the day as well as at night. I really do need it to sleep after say 5 minutes of idle time.

I have, btw, found the "NETWORK" option in KoReader. I'll try to connect to calibre again later today, to see if I can get that working. I thought the WiFi was on, but maybe it matters where it got turned on (KSM or KoReader). That was in the other thread, wherever that thing is, LOL!

Thanks for your help.
