What "Battery Not Charging" Actually Means
When your Mac displays "Battery Not Charging" in the menu bar or System Settings, it means your power adapter is plugged in but macOS has detected that the battery is not receiving a charge. This is different from your Mac straightforward running on battery power — the system is actively telling you something is blocking the charging process. The culprit is usually one of three things: a problem with the power adapter itself, a loose or damaged charging cable, or an issue with the battery or charging port on your Mac.
The message does not mean your Mac will stop working when ready. Your computer will continue to run as long as the power adapter is connected, even if the battery is not charging. However, if you unplug the adapter, your Mac will run on whatever battery charge remains, so identifying and fixing the problem is important if you rely on portable use.
Key Takeaways
- Disconnect and reconnect your power adapter, wait 30 seconds, then check System Settings to see if the status changes.
- Inspect the charging cable for visible damage, kinks, or fraying, and test with a different cable if one is available.
- Reset the System Management Controller (SMC) by shutting down, holding Power for 10 seconds, releasing, waiting 5 seconds, then powering on again.
- If the problem persists after these steps, the issue is likely inside your Mac and requires service from Apple or an authorized repair provider.
Check Your Power Adapter and Cable First
Start with the simplest fix: disconnect the power adapter from both your Mac and the wall outlet. Wait 30 seconds, then plug it back in firmly. Listen for a click or feel for resistance — the connector should seat completely. Check the LED light on the adapter itself (if your model has one); it should be amber or green depending on your Mac's charge state. If the light does not turn on at all, the adapter may be faulty.
Next, inspect the entire length of the charging cable for visible damage. Look for kinks, crushed sections, fraying, or exposed wires. Pay special attention to where the cable enters the adapter and where it connects to your Mac — these are stress points where damage often occurs first. If you see any damage, the cable needs replacement. If the cable looks fine but you have access to another compatible power adapter, borrow it and test for 10 minutes to rule out adapter failure.
Clean the Charging Port on Your Mac
Dust, lint, or debris inside your Mac's charging port can prevent proper contact between the cable connector and the charging pins. Shut down your Mac completely and unplug the power adapter. Use a flashlight to look into the charging port on your Mac. If you see visible lint or dust, use a dry cotton swab or a soft-bristled toothbrush to gently clean inside the port. Do not use liquid cleaners or force anything into the port.
After cleaning, wait a few minutes, then reconnect the power adapter and power on your Mac. Check System Settings > General > About to see if the battery status has changed. If it still says "Battery Not Charging," move to the next step.
Reset the System Management Controller (SMC)
The SMC is the part of your Mac that controls power delivery and charging. Resetting it often resolves charging issues that are not caused by physical damage. The process differs slightly depending on whether your Mac has an Apple silicon chip (M1, M2, M3, etc.) or an Intel processor.
For Macs with Apple silicon: Shut down your Mac completely. Press and hold the Power button for about 10 seconds until you see "Loading startup options" appear on the screen. Release the button, wait 5 seconds, then press Power again to start up normally. This resets the SMC automatically.
For Intel Macs: Shut down your Mac. Press and hold Shift + Control + Option (all on the left side of the keyboard) plus the Power button at the same time for 10 seconds. Release all keys, wait 5 seconds, then press Power to start up. You may see the Apple logo appear and disappear during this process — that is normal.
After your Mac restarts, leave the power adapter connected and check the battery status again after 5 minutes. Sometimes the SMC reset takes a moment to take effect.
Check System Settings for Battery Details
Open System Settings and navigate to General > About. Click the "System Report" button, then select "Power" from the left sidebar. Look at the "Battery Information" section. Note the "Condition" field — it should say "Normal." If it says "Service Recommended" or "Replace Now," your battery itself may be failing and preventing charging as a safety measure.
Also check the "Cycle Count" number. This is how many times your battery has fully charged and discharged. Batteries naturally degrade over time, and a very high cycle count (typically over 1,000 for older Macs) can cause charging issues. If the condition is poor and the cycle count is very high, the battery may need replacement.
When to Seek Professional Service
If you have tried all the steps above and your Mac still says "Battery Not Charging," the problem is likely inside your Mac — either a faulty charging port, a failing battery, or an internal power management component. This is not something you can fix yourself without specialized tools and training.
Contact Apple Support or visit an Apple Store to schedule a repair. Bring your Mac and power adapter with you. If your Mac is still under warranty or covered by AppleCare+, the repair may be covered at no cost. If not, ask for a repair estimate before authorizing the work. In the meantime, you can continue using your Mac as long as the power adapter stays connected.
Frequently Asked Questions
Can I use my Mac while it is plugged in if the battery is not charging?
Yes. Your Mac will run normally on power from the adapter alone. The battery straightforward will not gain charge. You can work, browse, and use all features normally. Just remember that if you unplug the adapter, your Mac will switch to whatever battery charge is currently stored.
Does "Battery Not Charging" mean my battery is broken?
Not necessarily. The battery itself could be fine, but the charging circuit, port, or adapter could be the problem. That is why testing the adapter and cable first is important. Only if those are working and the SMC reset does not help should you assume the battery or internal charging hardware is faulty.
How long does an SMC reset take?
The reset itself takes about 10 seconds. Your Mac will restart normally after that, which takes another 1 to 3 minutes depending on your model. After startup, wait 5 minutes before checking the battery status, as the system sometimes needs a moment to recognize the charging state.
What if my Mac is very old — is it worth fixing?
That depends on your situation and budget. If the repair cost is more than 30 to 40 percent of what a replacement Mac would cost, many people choose to replace it instead. Ask Apple for a repair estimate first, then decide based on your Mac's age and how much longer you plan to use it.
