What "Battery Not Charging" actually means on your MacBook

When your MacBook displays "Battery Not Charging" in the menu bar or System Settings, it means the power adapter is connected but the battery is not accepting a charge. This is different from your Mac straightforward running on AC power — the system is actively telling you the battery itself has stopped charging. The issue is usually one of four things: a problem with the power adapter, a problem with the charging port, a battery that needs service, or a safety feature that has kicked in because the battery is too hot or too cold.

The message does not mean your Mac will not work. You can continue using it while plugged in. But it does mean the battery is not storing power for when you unplug, so you need to find out why and fix it before the adapter fails or you need to work away from an outlet.

Key Takeaways

  • Check that the power adapter cable is fully inserted into both the wall outlet and your MacBook, and look for visible damage to the cable or connector.
  • Restart your Mac with the power adapter connected, then wait 20 minutes to see if the charging status changes in System Settings.
  • If your MacBook is hot to the touch, unplug it and let it cool for 30 minutes — the battery will not charge if the internal temperature is too high.
  • Reset the System Management Controller (SMC) by shutting down, holding Power for 10 seconds, releasing, waiting 5 seconds, then powering on again.
  • If none of these steps work, the power adapter or battery likely needs replacement, which Apple or an authorized service provider can diagnose.

Check the power adapter and cable first

Start with the simplest cause: the connection itself. Look at where the power adapter plugs into your MacBook. On newer models with USB-C or MagSafe, the connector should sit flush and click or snap into place. On older models with MagSafe, the connector should be fully seated. If it is loose, push it in firmly and wait a few seconds to see if the charging light changes.

Inspect the entire cable from the wall outlet to the adapter brick. Look for cuts, fraying, bent pins, or burn marks. If you see damage, the cable needs replacement — a damaged cable can prevent charging even if it still carries power. Check the wall outlet itself by plugging in another device (a phone charger, lamp, anything) to confirm the outlet works.

If the cable looks fine, unplug it from both the wall and your MacBook, wait 10 seconds, and plug it back in. Sometimes a loose connection or a brief power glitch causes the system to stop recognizing the adapter as valid.

Restart your Mac and wait for the system to recognize the adapter

Leave your MacBook plugged in and restart it. To do this, click the Apple menu, select Shut Down, wait for the Mac to power off completely, then press the power button to turn it back on. This forces the system to re-detect the power adapter and re-evaluate the battery.

After restart, open System Settings (or System Preferences on older macOS versions), go to Battery or Power Adapter, and check the status. Sometimes the charging status updates within a few seconds of restart. If it still says "Battery Not Charging," wait another 20 minutes with the Mac plugged in and the screen on. Occasionally the system needs time to recognize that the adapter is present and valid.

Cool down your MacBook if it is hot

MacBooks have a built-in safety feature: the battery will not charge if the internal temperature is too high. This protects the battery from damage. If your MacBook feels hot to the touch, especially near the keyboard or bottom case, this is likely the reason for the "Battery Not Charging" message.

Unplug the power adapter and shut down your Mac. Leave it in a cool room (not in direct sunlight, not on a bed or pillow) for at least 30 minutes. Do not use it during this time. After it has cooled, plug it back in and restart. The charging status should return to normal once the internal temperature drops.

If your Mac runs hot regularly, check Activity Monitor (Applications > Utilities) to see which apps are using the most CPU. Close unnecessary browser tabs, quit apps you are not using, and make sure the vents on the bottom and sides of the case are not blocked by dust or fabric.

Reset the System Management Controller

The System Management Controller (SMC) is the part of your Mac that manages power, charging, and thermal behavior. If it gets confused about the power adapter or battery state, resetting it can fix the problem. The steps depend on whether your Mac has an Apple silicon chip (M1, M2, M3, or newer) or an Intel processor.

For Apple silicon Macs (M1 and newer): Shut down your Mac completely. Press and hold the power button for 10 seconds, then release it. Wait 5 seconds. Press the power button again to turn it on. The SMC resets automatically during this process.

For Intel Macs: Shut down your Mac. Press Shift + Control + Option (all on the left side of the keyboard) + Power button at the same time. Hold all four for 10 seconds, then release. Wait a few seconds, then press Power to turn it back on.

After the reset, plug in your power adapter and check the battery status in System Settings. This step fixes the "Battery Not Charging" message in many cases because it clears any incorrect state the SMC was holding.

Check for macOS updates and battery service messages

Open System Settings and go to General > Software Update. If an update is available, install it. Apple sometimes releases updates that fix charging issues or improve how the system communicates with the battery and adapter.

While you are in System Settings, go to Battery (or Power Adapter on older versions) and look for any message that says "Service Recommended" or "Replace Now." If you see this, the battery itself has degraded and needs replacement. This is different from "Battery Not Charging" — it means the battery is still charging but is no longer healthy enough to hold a full charge. You can still use your Mac, but you should plan to have the battery replaced soon.

When to contact Apple or a service provider

If you have tried all the steps above and your MacBook still says "Battery Not Charging," the problem is almost certainly the power adapter or the battery itself, and neither can be fixed at home. The power adapter may have failed internally even though the cable looks fine. The battery may have a hardware fault. The charging port may be damaged.

Contact Apple Support or visit an Apple Store with your MacBook and power adapter. Bring your receipt or proof of purchase if your Mac is still under warranty — battery and power adapter issues are often covered. If your Mac is out of warranty, Apple can tell you the cost of replacement before you commit. Authorized third-party repair shops can also diagnose and replace these parts, often at lower cost than Apple.

Frequently Asked Questions

Can I use my MacBook while it says "Battery Not Charging"?

Yes. As long as the power adapter is plugged in, your Mac will run normally. The issue is that the battery is not storing power, so if the adapter fails or you unplug it, your Mac will shut down when ready. You can work this way temporarily, but you should fix the problem before relying on your Mac away from an outlet.

Does "Battery Not Charging" mean the battery is broken?

Not necessarily. The battery itself may be fine — the problem could be the power adapter, the charging port, or a temporary software glitch. That is why restarting and resetting the SMC often fix the issue. If those steps do not work, then the battery or adapter likely needs replacement.

Why does my MacBook stop charging when it gets hot?

Apple built in a safety feature to protect the battery. Lithium batteries can be damaged by charging at high temperatures, so the system stops charging if the internal temperature gets too high. This is normal behavior and protects your battery from permanent damage. Let your Mac cool down and it will resume charging.

How long does it take to fix "Battery Not Charging" at an Apple Store?

Diagnosis usually takes 15 to 30 minutes. If the power adapter needs replacement, Apple can often do it the same day. If the battery needs replacement, it typically takes one to three business days because the work requires opening the case and testing the repair.

Will resetting the SMC erase my files?

No. Resetting the SMC only clears temporary power and thermal settings. Your files, apps, and settings remain untouched. It is safe to do and causes no data loss.
