Description Ryan 2010-08-11 09:15:34 UTC

It has now been discovered what is the true cause of the battery not charging when installed. Referance bug 16440.

The factory test was issuing the battery_disable command , this state is then remembered by the radio and later when a battery is first installed the battery is detected but not charged. 

The code should change so that when the battery is detected it is enabled by default.

Discharging the "super cap" will cause the unit to forget this state and allow charging the next time a battery is installed. 



to turn on charging:
    # echo 1 > /sys/bus/i2c/devices/1-0010/battery_disable

to turn off charging:
    # echo 0 > /sys/bus/i2c/devices/1-0010/battery_disable

OK for Suzhou since OOB testing does not use battery. Also supercap will discharge completely before customer opens box.

Want to charge battery if new battery inserted and supercap not discharged.
