MacBook won't charge – MagSafe, USB-C port and charging faults
Last updated:
Quick answer
When a MacBook won't charge, the cause in priority order is: 1) the charger or cable itself (test with a known-good charger), 2) debris in the USB-C port (check with a flashlight), 3) a faulty charging port or controller on the logic board (requires repair at our workshop).
My MacBook won’t charge — quick diagnosis
95% of all “won’t charge” cases have one of three causes:
- The charger is dead — test with another, known-good charger
- The port is full of lint — shine a light inside, use compressed air
- The cable is broken — check for visible damage, especially at the connector
If none of those three resolves it, it’s the charging circuit on the logic board — and that requires a specialist.
How to clean the USB-C port safely
USB-C ports are small and they collect lint from pockets and bags. Symptom: the charger only works at certain angles, or nothing at all.
- Power off the MacBook and unplug the charger
- Shine a flashlight into the port with an LED torch. You can spot dust as a grey lump at the back
- Use compressed air (a short burst, not too close)
- If dust is still stuck: use a wooden or plastic toothpick. NEVER metal (it shorts out the pins)
- Test the charger again
Which charger should I use?
| MacBook | Recommended wattage |
|---|---|
| MacBook Air M1/M2/M3 | 30W or higher USB-C |
| MacBook Pro 13” M1/M2 | 67W USB-C |
| MacBook Pro 14” M1/M2/M3/M4 | 70W or 96W USB-C |
| MacBook Pro 16” M1/M2/M3/M4 | 140W USB-C MagSafe |
You can always use a more powerful charger without risk — it only delivers what the MacBook is asking for. A charger that’s too weak will either charge very slowly or fail to keep up under load.
Where can I get it repaired?
We replace every type of charging port — USB-C, MagSafe 1, 2 and 3 — and we can repair burnt charging circuits at the component level via micro-soldering.
Typical turnaround: same day or the next day for in-person drop-off. Mail-in: 2-4 working days including shipping.
How to diagnose charging faults yourself
⏱ PT5M
- Test the charger first. Borrow a KNOWN-good Apple charger from another Mac and try it. Or test your charger on another Mac. If the other charger works = it was your charger. If your charger works elsewhere = it's the Mac.
- Shine a flashlight into the port. Lint and pocket dust are the most common cause of charging issues. If you can see a grey clump at the back of the USB-C port, that's the culprit. Use compressed air (a short burst) or a wooden/plastic toothpick. NEVER metal — it shorts out the pins.
- Test every USB-C port. On MacBooks with multiple USB-C ports: try each one. If only one port charges, the faulty port is a separate replacement (DKK 1,500-2,200) — you don't need to swap the whole logic board.
- Check the cable for kinks. Gently wiggle the cable at the charger and at the Mac connector. If charging cuts in and out depending on the angle, it's the cable (typically wear at the connectors). New Apple cable: DKK 200-400.
- Check the MagSafe connector for dust. On MagSafe models: check the magnetic contact pads for dust or discolouration. Wipe with a dry, lint-free cloth. Brown/black discolouration can indicate a burnt contact — get in touch with us.
- Book a diagnosis if nothing works. If no charger, no port and no cable works, it's the charging circuit (PMIC) on the logic board. That requires micro-soldering with us: DKK 2,500-3,500. Diagnosis is free.
