Logic Board Assembly
The logic board contains the primary Power Management ICs (PMICs) and Thunderbolt controllers responsible for negotiating power delivery. When both MagSafe and USB-C ports fail to charge, it indicates a failure in the shared power rail or negotiation logic on the main board rather than individual port hardware.

USB-C Board
Internal pins in the USB-C ports can wear or short, occasionally causing a system-wide protection 'lockout' that prevents charging via other ports. Replacing these modular boards is the standard first step in field service exclusion testing.

MagSafe 3 DC-In Board
Though less likely to cause a total USB-C charging failure, a shorted MagSafe 3 connector can pull down the primary power rail (PPBUS_G3H), effectively disabling the charging circuit for the entire system.
