Hmm but does it automagically s2ram? Or only when I lock? So for example, it would perform s2ram with autolock?

I guess WOL doesn't really have anything to say in this situation.

I've solved the problem again in the same fashion as I did before: let battery load till it is full, disconnect the charger, boot. 1st time it hangs. Then boot again, then it somehow works. Don't ask me why...

Right now the device is off power, blinking LED, s2ram'ed (AFAIK?!).

Fixing the connection to its state before it went s2ram might be nice... don't know... the device might have moved to a place where that connection isn't available...?

PS: Approx every minute the screen lights up a bit to a very dark screen. Is this related to the watchdog you talk about?
