I have no idea why someone would tell you the problem is the South Bridge chip
A southbridge chipset handled the many of a computer's I/O functions, such as USB, audio, the system BIOS, the ISA bus or the LPC bus, the low speed PCI/PCIe bus, the IOAPIC interrupt controller, the PATA/SATA storage, and the NVMe storage.
None of these are related to the battery because that is Power, not I/O.
Besides, that chip is soldered to the system board and can not be replaced.
