Is it possible to automatically hibernate the Pocket Edge

[3ruce]

Without closing the lid?

I've not come across anything yet, other than the power button and closing the lid. AutomateIt doesn't work but I wonder if something like Tasker would work?

My guess is that its going to be tricky given that only a few Android tablets will have this 'hibernate' feature, hence it being tricky to activate it via other means...

Any thoughts anyone?

# echo mem > /sys/power/state

(requires root I imagine)

"should" do it, but I'm not sure that's exactly what the hibernate does - everything seems to sleep but the reader side doesn't change to display the wakeup instructions and I don't think the power led went from solid to blinking (not surprising - there's probably some hibernate script I'm missing that is triggered when you close the device)

finding the actual hibernate script would be best, I'd think...

Thank you... any pointers on where to look? My device is rooted btw...

not exactly sure, I was looking in all the usual places in /etc for suspend/resume type stuff and there wasn't any of that, no acpi etc. - doing global "find /" for things like hibernate, sleep, suspend, resume etc. - and nothing.

smarter way to go about it would be to watch adb as it hibernates and see what's called... so I did, and it looks like the window manager gets notified and has X seconds to hold onto a lock (whatever you've set in your settings menu e.g. mine is 15 seconds) before the power manager suspends the machine.

(also: looking at adb, the echo to sys power state I mentioned above, doesn't really do anything - it looks like it tries, but just doesn't follow through.)

so, looks like it's all sys event calls to the kernel (which still surprises me a little, given that they change the background on the reader site when it hibernates)

doubt this is particularly helpful, but here's the log as it hibernates:

(writing code against PowerManagerService might be worth a try)
