Why each option
The DC power jack on a laptop is typically soldered directly to the motherboard, making replacement a re-soldering operation rather than a simple plug-and-play swap.
Mini PCIe wireless cards connect via a standard Mini PCIe slot and are replaced by simply unplugging and reseating - no soldering required.
Heat sinks are typically secured with screws and thermal paste and can be replaced without any soldering.
Unlike most laptop components that use connectors or sockets, the DC jack is hardwired to the motherboard via solder joints. Replacing it requires desoldering the old jack and re-soldering the new one to the board, making it a significantly more involved repair than other component swaps.
Li-Ion laptop batteries are designed to be user-replaceable via a latch or screws and do not require soldering in most systems.
