Symptoms
- Magnetic connector doesn't snap into place as firmly as before
- Charging light doesn't come on even when the connector appears attached
- Connection is intermittent, cutting in and out
- Connector feels weak or loose compared to when it was new
Likely causes
- CommonDust, lint, or metal shavings stuck to the magnetic contactsDebris breaks the electrical contact even if the magnet still grips.
- CommonWeakened magnets from age or heat exposureRepeated heat cycles can slightly weaken the magnetic connection over years.
- PossibleDamaged or frayed cable near the connectorInternal wire damage can cause an intermittent connection even with a good magnetic grip.
- PossiblePort-side contacts on the laptop are dirty or damagedThe laptop side of the connection can accumulate debris too.
What to do
- Unplug the charger and clean both the connector and the laptop's charging port contacts with a dry, lint-free cloth.
- Check for any metal shavings or debris stuck to the magnetic pins, which are easy to miss.
- Try gently wiggling the connector once attached to see if the connection is intermittent, pointing to a cable issue.
- Test with a different MagSafe/magnetic cable if available to isolate cable versus port.
- Avoid setting the charger down near metal shavings, coins, or other magnetic debris sources.
- If the magnet grip itself feels weak (not just electrical connection), the cable's magnet may be worn and need replacement.

When to call a pro
If cleaning doesn't restore a solid connection, replacing the cable is usually sufficient; if the laptop-side port is damaged, professional repair is needed.
