The MacBook Air M2 gives you three ways to charge it, and each fails differently. MagSafe 3 is the magnetic port on the left; there are two USB-C Thunderbolt ports as well, and any of them can charge the Air from a USB-C power adapter. An M2 Air that does not charge might have a bad cable or adapter, a dirty port, or a software setting, and one iFixit thread describes an M2 Air where both MagSafe and the USB-C ports stopped working, which points at the board.
Apple's order is: check the outlet, try the other port, test another cable and adapter, rest the adapter for sixty seconds, and look at the wattage, because the Air M2 with the 10-core GPU is sold with a 35 W dual-port or a 67 W adapter and charges slowly on a phone-sized brick.
Differential
Likely causes of “Apple MacBook Air (M2) will not charge”, and how to tell them apart
- 1
A cable or adapter that is damaged or under-powered
What separates it The light on the MagSafe plug stays off, or the Mac charges very slowly
How to confirm Try a known-good MagSafe 3 cable, and a USB-C adapter of 30 W or more
- 2
Debris in a port
What separates it The magnet will not seat, or the USB-C plug wobbles
How to confirm Look into the port with a flashlight and clear lint gently with a wooden toothpick, Mac off
- 3
A software state
What separates it The battery icon shows not charging though the adapter is connected
How to confirm Restart; then check System Settings, Battery, and Battery Health
- 4
The adapter needs a rest
What separates it The adapter stopped after getting hot
How to confirm Unplug it for sixty seconds, plug it into a different outlet
- 5
A board or port fault
What separates it Both MagSafe and USB-C ports fail with several cables and adapters
How to confirm Book Apple; the charging circuit is on the board
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether MagSafe, USB-C or both fail
- The adapter and cable models, and their wattage
- The color of the MagSafe light, if any
- Battery cycle count and health

Model-specific
What is true of this model and not of its siblings
- Three ways to charge
- MagSafe 3 and two USB-C Thunderbolt ports, any of which can charge the Air.
- Adapters
- The M2 Air is sold with a 30 W, 35 W dual-port or 67 W adapter depending on the configuration.
Stop boundary
When this stops being a self-service repair
- !If every cable and adapter fails on both port types, book Apple for the charging board
- !If the MagSafe port is damaged or the magnet has come loose, it needs Apple
- !A swollen battery is a same-day visit
