MacBook Not Charging, Fixes That Work

A MacBook that will not charge is rarely a dead MacBook. Most cases come down to a bad cable, a wrong-wattage adapter, lint in the USB-C port, a charge limit doing its job, or the power controller stuck in a bad state. Work through the fixes in order, cable first.

First, check the cable, adapter, and port

Check the charger wattage. A MacBook needs an adapter that matches it: a low-wattage or phone charger can run the MacBook but not charge it. Use the adapter that came with the MacBook, or an equivalent USB-C charger with enough watts for your model.
Try a different cable and port. Cables break inside even when they look fine. Try a cable you know works, and try a different USB-C port on the MacBook.
Check the outlet. Try a different wall outlet, and plug straight into the wall rather than a power strip or a laptop USB port.
Clean the port. Shine a flashlight into the USB-C port and look for lint or debris. Clear it gently with a wooden or plastic toothpick. Never use metal.
Look at the battery icon. In System Settings, Battery, check the Battery Health condition. If it reads “Service Recommended” or “Service Battery”, the battery has reached the end of its useful life and no reset will extend it.

Check whether a charge limit is pausing it

Optimized Battery Charging, on by default on macOS Big Sur and later, intentionally pauses charging at 80% during long plug-in periods to slow battery aging. If the battery sits at 80% and will not go higher, that is the feature working. In System Settings, Battery, you can turn it off or choose Charge to Full Now for the current session.

Reset the power controller

The System Management Controller (SMC) manages charging on Intel MacBooks, and it can enter a state that blocks charging after a power event or a failed update. This is the single most effective fix when the cable and charger check out.

Intel MacBook with T2 chip (2018 and later): shut the Mac down, press and hold Control, Option, and Shift (left side) for 7 seconds, then keep holding them and add the power button for another 7 seconds. Release everything, wait a few seconds, then press the power button to start up.
Intel MacBook without T2 chip (2017 and earlier): shut the Mac down, press and hold Shift, Control, Option (left side), and the power button at the same time for 10 seconds, release, then press the power button to start up.
Apple Silicon MacBook (M1, M2, M3, M4): there is no SMC key combination. Apple states the SMC resets automatically on Apple Silicon Macs, so shut the Mac down, wait 30 seconds, and start it up again.

After the reset, reconnect the charger and watch the menu bar: the charging indicator should appear within a few seconds. You can also reset NVRAM on Intel Macs by starting up and immediately holding Command, Option, P, and R until you hear the startup sound. This step does nothing on Apple Silicon.

If it still will not charge

Update macOS: charging bugs are fixed in software updates. If the battery health condition is “Service Recommended”, or the MacBook only charges with one specific cable and port, the battery or the charging port needs service. If the MacBook is still under warranty or covered by a service plan, contact Apple before paying for a repair. A swollen battery, a bulging case, or a chemical smell is a safety issue: stop charging it and get professional help.

Common questions

Why does my MacBook stop charging at 80%? That is Optimized Battery Charging, on by default on macOS Big Sur and later. It pauses at 80% during long plug-in periods to slow battery aging. In System Settings, Battery, you can turn it off or choose Charge to Full Now for the current session.

Does the SMC reset work on Apple Silicon MacBooks? No, there is no SMC key combination on Apple Silicon. Apple states the SMC resets automatically on Macs with Apple silicon. The equivalent step is a full shut down, a 30-second wait, and a normal restart.

What does “Service Recommended” mean on my MacBook battery? It means the battery has degraded past the point where it can hold a useful charge, and macOS is telling you it needs service. No reset or setting will restore it. The battery needs replacing, ideally through Apple or an authorized service provider.
