Review the MCP73831 datasheet. The battery is connected to VBUS through a diode. Will the MCP73831 try charging the battery if the system is on battery power? If so, add a switching circuit like what is on the T400.
From the MCP73831 datasheet. The input voltage much be 150 mV above the battery voltage for the MCP73831 to become operational
