Attach the battery and power adapter.
Measure and post the voltage on the battery SMB lines. There is the SCL (Clock) & SDA (Data) lines used by the SMB Host (Master) to ping the battery (SLAVE) to determine its stats.
255 decimal = FFh (hex). Guessing that the bus is reading back 255 as a value from the battery.

3.3V on both of those. |
