Try a known-working cable, compatible charger and wall outlet before changing settings. Inspect the connectors for damage. A temperature warning or charging limit can pause charging intentionally. The model checks below separate a power-source problem from a worn battery or a damaged charging connection.
Differential
Likely causes of “Apple MacBook Air will not charge”, and how to tell them apart
- 1
An under-powered or non-Apple charger
What separates it The Air charges slowly, or the battery falls while plugged in during heavy work
How to confirm Use the adapter that came with it or a USB-C power adapter of at least 30W, and a cable rated for charging
- 2
A faulty cable or a dirty MagSafe 3 or USB-C connector
What separates it Charging starts and stops when the cable moves
How to confirm Try a second cable and the other port, and look in the connector with a flashlight for lint
- 3
Optimized Battery Charging
What separates it The Mac says Charging On Hold or stops at 80 percent
How to confirm Choose Charge to Full Now from the battery menu, or change the setting under System Settings, Battery
- 4
A software or SMC-style glitch
What separates it It will not charge after an update or a long sleep
How to confirm Restart, then shut down fully, unplug for a minute and start up again
- 5
A battery or charge-port fault
What separates it A known-good adapter and cable still give no charge, or the Air only runs while plugged in
How to confirm Battery Health may say Service Recommended; book an Apple check
Before you touch a setting
Record this first — changing settings destroys the evidence
- Which adapter and cable you used, and whether the MagSafe light comes on
- The Battery Health message and the maximum capacity
- Whether the other USB-C port or another charger behaves differently
- Which Air it is: M2, M3 or M4, 13 or 15 inch
Try in this order
0 of 6 completedTest the wall and the adapter
ReversiblePlug the adapter into a different outlet and check that its light or the MagSafe 3 light comes on.
Swap the cable and the port
ReversibleUse a second charging-rated cable, and move it to the other USB-C port on the left side if you are not using MagSafe.
Clean the connector
ReversibleWith the Air off, shine a flashlight into the port or the MagSafe socket and lift any lint with a wooden toothpick.
Check the charging setting
ReversibleOpen the battery menu and look for Charging On Hold; pick Charge to Full Now if you need a full charge today.
Restart and fully power down
ReversibleRestart, then shut down, unplug everything for a minute and start up with only the charger connected.
Read Battery Health
ReversibleIn System Settings, Battery, check Battery Health. Service Recommended means the battery needs replacing.
Model-specific
What is true of this model and not of its siblings
- Apple MacBook Air (M2, M3 and M4) will not charge
- If a MacBook Air (M2, M3 or M4) will not charge, work from the plug to the battery. Check that the adapter lights or the MagSafe 3 connector shows its green or amber light, then try the other USB-C port with a different cable, since many USB-C cables are charge-poor or data-only. A menu bar battery icon that shows a plug but no charging often means the charger is under-powered for the load, or Optimized Battery Charging is holding at 80 percent. Restart the Air, then shut it down and unplug everything for a minute. If it still draws nothing on a known-good Apple adapter and cable, the charge port or the battery needs Apple.
- M2, M3 and M4
- All three generations charge over MagSafe 3 or the two USB-C ports. The M2 and M3 ports are Thunderbolt 3 / USB 4 and the M4 ports are Thunderbolt 4.
- Battery sizes
- Apple lists about 52.6 Wh in the 13-inch M2 and M3, 53.8 Wh in the 13-inch M4 and 66.5 Wh in the 15-inch models, so the 15-inch takes longer to charge on a small adapter.
- Repair cost
- Apple quotes charge-port and battery repairs after diagnosis. iFixit's table lists Apple's US battery estimate for a MacBook Air.
- Other models this page answers
- These steps also fit the MacBook Air 15-inch (M3).
Stop boundary
When this stops being a self-service repair
- !If a known-good Apple adapter and cable do not charge it after a restart, contact Apple
- !If the case is bulging or the trackpad has lifted, stop and take it to Apple
- !If the Air only works when plugged in and shuts off the moment it is unplugged, book a battery check

Exact questions
Common questions
Why does my MacBook Air say Not Charging although it is plugged in?+
The charger may be too weak for what the Air is doing, the cable may be charge-poor, or Optimized Battery Charging may be pausing at 80 percent. Try the original adapter and cable first.
Can I charge a MacBook Air from either USB-C port?+
Yes. Both left-side Thunderbolt ports and MagSafe 3 can charge it, so if one port fails and the other works, the port is the fault.
What wattage does a MacBook Air need?+
The 13-inch models ship with a 30W or 35W adapter and the 15-inch with a 35W dual-port adapter; a 70W adapter charges faster on models that support fast charging.
Is it safe to use a third-party MagSafe cable or adapter?+
A reputable USB-C Power Delivery adapter and cable work, but a cheap one can charge slowly or intermittently. Test with Apple's own before blaming the Mac.
