Lenovo 330W GaN Slim Tip AC Adapter
The proprietary slim-tip connector includes a center 'sense' pin that communicates the adapter's wattage to the system via a resistor divider. If the internal circuitry of the switching power supply fails or the sense pin is damaged, the laptop's Power Management Integrated Circuit (PMIC) will default to a 'No Charge' state as a safety protocol to protect the motherboard from unverified power sources.

Rechargeable Li-ion Battery Pack (99.9Wh)
When a high-performance battery reaches 0%, the cell voltage may drop below the critical termination threshold. The internal Battery Management System (BMS) logic gate will 'blow' an electronic fuse to prevent the charging of potentially unstable cells, resulting in a 'Plugged in, Not Charging' status that cannot be recovered via software.

DC-In Jack Power Cable Harness
The DC-in jack on this model is a modular harness connected to the motherboard. High thermal output from the adjacent cooling exhaust can cause the plastic housing of the jack to become brittle, leading to a loss of tension in the spring-loaded contacts or a fracture in the wire harness that carries the 'AC_IN' signal to the charging circuit.
