APPLE MACBOOK PRO 14-INCH (M1 PRO, 2021) Not Charging Mag Safe

USB-C to MagSafe 3 Cable (2 m)

The MagSafe 3 cable contains a microcontroller that performs a digital handshake with the laptop's Power Management Integrated Circuit (PMIC). The physical spring-loaded pogo-pins often suffer from 'pin-stuck' syndrome or microscopic carbon buildup on the contact surfaces, which prevents the 1-Wire communication protocol required to initiate the 20V charging rail.

MagSafe 3 DC-In Board

This is the internal modular port that receives the MagSafe connector. The port can suffer from mechanical fatigue or ESD (Electrostatic Discharge) damage to the sensing pins, resulting in a failure to detect the presence of the charger despite the magnetic connection being physically secure.

67W/96W USB-C Power Adapter

Internal capacitor failure or logic board fault within the AC adapter can cause it to fail to output the high-wattage DC profile requested by the MacBook, though this usually results in no LED light on the cable at all.
