Alfa21 freerun...@my.is.it writes: afaik the difference is in the std-by power consumption and I think any script does not run during the std-by power state. You can measure suspend power consumption by taking a reading immediately after resume. mmh.. a question: I do not remember how to verify if it goes in sleep or in deep-sleep What are these? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I think that the kernel is responsible to turn wifi off in suspend (unless you want to keep it on during suspend e.g. for wake-on-wlan function). So if there is high current in suspend it is probably kernel related problem. Unbinding the adapter seems to me quite ugly workaround. I would like to check it myself, but i am right now in the middle of too many things.

Alfa21-mobile freerun...@my.is.it writes: maybe deep-sleep is only related to the gsm-chip power state? I'm not sure. btw I've hardware fix #1024 and deep-sleep enable in neocontrol. Indeed. I thought this thread was about wifi. If you measure wifi consumption you better power down your GSM, bluetooth, backlight, accelerometer, GPS. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Yes, in suspend the kernel turns off the module completely, it shouldn't drain anything, at least it never used to. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercer...@gmail.com ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
