DC-In Jack Cable Assembly
The DC-in port on this model is a modular harness prone to mechanical fatigue from physical connector insertion cycles. Over time, the internal contact leaves lose their spring tension or the wire harness fractures at the stress-relief point near the hinge, resulting in high resistance or an open circuit. Replacing this granular cable restores the electromechanical path between the AC adapter and the motherboard's power management IC.

Internal Lithium-Ion Battery
The internal battery's Protection Circuit Module (PCM) can enter a permanent failure state if it detects a cell voltage imbalance or thermal excursion. Once the chemical health of the cells degrades beyond a specific threshold, the firmware prevents charging to mitigate the risk of thermal runaway. This is a common failure mode when the device is frequently used under high thermal loads or after several hundred charge cycles.

65W AC Wall Adapter
The external transformer may experience failure of the output capacitor or fatigue of the copper braiding within the DC barrel cord. If the adapter cannot maintain a stable voltage under the load of the system's power-on state, the charging logic will reject the input to protect the internal MOSFETs. This is often indicated by the charging LED failing to illuminate despite a secure connection.
