Could a failing Internal Lithium-Ion Battery Pack cause the ACER SWIFT 3 (SF314 SERIES) to have symptom: Not Charging?

The Battery Management System (BMS) circuit board within the pack often triggers a hardware lockout due to cell impedance mismatch or a firmware error. Once the lockout FET (Field Effect Transistor) is triggered, it physically interrupts the charging path to prevent thermal runaway, making the battery appear dead to the OS despite having healthy cells.

Could a failing DC-In Power Jack Cable cause the ACER SWIFT 3 (SF314 SERIES) to have symptom: Not Charging?

This model uses a modular DC jack that communicates with the SuperIO chip via a dedicated sense line. Mechanical fatigue or oxidation of the internal signal pin prevents the motherboard from identifying the wattage of the power adapter, causing the charging controller to default to a 'No Charge' safety state while still allowing the system to boot.

Could a failing Case Interlock Microswitch Shim cause the ACER SWIFT 3 (SF314 SERIES) to have symptom: Not Charging?

Acer Swift 3 motherboards feature a small safety microswitch that must be fully depressed by a plastic post on the bottom cover. If the chassis is warped or the plastic post is slightly compressed, the switch opens, and the Embedded Controller (EC) hardware-disables the charging circuit as a safety precaution against operation while the battery is exposed.
