LiCoO2, Li-Ion Battery Fuel Gauge, Status Monitor, 2.45 V to 4.5 V supply, I2C interface, DSBGA-9. The idea was to define a single standard that could be used both inside and outside a computer. A single I²C/A.b controller chip would be used inside the machine, connected on the motherboard to internal devices like the clock and battery power monitor. An A.b connector on the outside would then allow additional devices. And pin 3 definitely looks like an I2C clock, pulsing nonstop during the comm intervals, while pin 4 looks like an I2C data. Ok we've just confirmed 3 and 4 are indeed the SMbus pins and the battery is talking to the charger. That seems to indicate it is alive, but too discharged to allow for charging- most likely.
