DC-in Jack Power Cable Harness
The Legion 5 utilizes a modular power jack harness that is prone to mechanical fatigue from the weight of the 230W/300W power adapter. Internal pins lose tension or the plastic housing cracks, resulting in a loss of the 'Sense' signal that identifies the charger wattage. This part replaces the entire port-to-motherboard connection, bypassing any physical damage at the socket.

Lenovo 230W AC Adapter (Slim Tip)
The 'Slim Tip' rectangular connector on the charger side can suffer from internal wire fraying or a broken center pin. If the laptop fails to receive the correct resistor ID from the center pin, it will refuse to charge the battery even if it can still power the system in a throttled state.

Internal Lithium-ion Battery Pack
If the DC-in port and charger are verified functional with a multimeter, the battery's internal management circuit (BMS) may have tripped a permanent failure flag due to a cell imbalance or deep discharge state, preventing the charging MOSFETs from opening.
