[maemo-developers] 770 auto shutdown problem

Dear All,

Thanks for your comments on my shutdown problem, sorry its taken a while
to get back to you but I was waiting for a new battery and being on

So: I reflashed the unit (latest 2006) and put it in R&D mode (green
info text on startup) and I was still seeing the same problem, namely
the 770 decides to turn itself off rather than entering a low power
standby state after a period of inactivity.

I bought a new battery and have tried that too and I am getting the same

Even with the old battery, energy levels are not low, I can use the
device for ages on constant usage its just if I close it, when I come
back (even after a short time, say 10 minutes) the device is dead.

Apart from monitoring the dbus, does anyone have an idea on how I can
try to trace what's happening when it shuts down?  Are there any clever
ways of recording the sequence of events that would lead to a shutdown?
Does anyone know the logic that leads to shutdowns or stanby actions?
Is the code that governs this open?  Could someone point me to it?

AFAIK this is normal, it's sent always when screen is blanked.
