Hello,

I am trying to do a system lifetime test of a system I have with the N810 as the "brain" and another device on the USB. I wrote a small Python program that constantly writes the alive time so far to a file and whenever my USB device or the Nokia runs out of battery, the program stops. However, every time I've run the program so far, I've gotten an alive time of 3600 seconds, which is exactly 1 hour. I doubt that this is the "real" lifetime and rather some power saving feature. I've tried searching for such features but can't seem to find anything. Do you know how I can disable this "feature"?

Best regards,
Schoel

Interesting. I've not heard of a 1 hour timeout anywhere, but maybe you've discovered one. For troubleshooting purposes, what happens if you simplify the program to take out the USB stuff, and just write continually to a file - does that stop after 1 hour too?
