To the best of my knowledge, the NOR u-boot doesn't implement the bq27x0 HDQ driver, and hence it has no way to distinguish between a dumb battery and an original one. So it should be able to charge any battery without any issues. -- 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

Re: GTA02 fails to charge
I have a doubt about this because my FreeRunner only lasts 1 day charged and I want to use it more now, I read this thread and like Ivan, the first thing that comes to my mind is: new battery, do you know what models of batteries works fine with FreeRunner (let's say Nokia's 1100 or so)??

I get ~4-5 days out of a battery when the phone is sleeping and that's with little to no usage and ~24-36hrs if I keep it awake without using bt/gps/gprs/wifi.

If you have a compatible Nokia battery give one a shot and see if it fares better. Before buying another battery you should also verify the charge rate. I haven't experienced any issues charging off of usb ports on laptops or desktops and using the original wallwart always works. I do have a mobile charger (rocketfish model rf-rzr55) that only charges @ 100mA which isn't enough to keep the battery from discharging. You can force fast charge (500mA or 1000mA) for non smart usb connections. Details here: http://wiki.openmoko.org/wiki/Forcing_fast_charge_mode I think the paths differ for more recent kernels so maybe someone on the list has the correct paths to use and can update the wiki or post to the list. HTH and good luck! Brian ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

GTA02 fails to charge
I have 2 GTA02v6 Freerunners which don't charge their batteries anymore. The symptoms on both are the same, but it started happening on both phones in different locations and times. The battery state is Charging whether the phone is plugged in to a computer or wall charger, but the battery slowly goes down instead of charging. We use the phones in airplanes, connected to 5V DC power supplies. My wild guess is that both units might have experienced a power surge or something that fried the charging circuit (RT9711BPB chip in socket U4905?). With 2 Freerunners affected and afraid it might happen a third time, I would like to know if anyone else has experienced this problem. -Phil ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
