Its USB-C and MagSafe ports are documented separately, along with the battery, screen and trackpad.
What to check before buying
Ports
iFixit has separate procedures for one or both USB-C ports and for the MagSafe connector. A charging issue through only one connector can narrow the component involved.
Other assemblies
The battery, display, left and right speakers, Touch ID sensor and trackpad also have model-specific guides. Match the 2024 M3 15-inch revision rather than the 13-inch Air.
