How to Fix Mac Not Charging
Common Causes of Mac Not Charging
Before diving into solutions, it’s important to understand why your Mac may not be charging. There are several possible causes:
Faulty Power Adapter or Charging Cable: One of the most common causes of charging issues is a damaged or malfunctioning power adapter or charging cable.
MacBook Battery Health: If your MacBook's battery is old or has been heavily used, it may not be charging properly, especially if it’s nearing the end of its lifespan.
Power Source Problems: If the outlet or power strip you are using is malfunctioning or has low power, your Mac might not be charging.
System Preferences or Software Bugs: Sometimes, a system error or a bug in macOS can prevent your Mac from recognizing that it’s plugged in.
Connection Issues with the Charging Port: Dirt, debris, or damage to your Mac’s charging port can prevent a solid connection between the adapter and your Mac.
Let’s go over the troubleshooting steps to help you resolve these issues.
Troubleshooting Steps to Fix Mac Not Charging
1. Check the Charging Cable and Power Adapter
The first thing to check is your charging equipment. A damaged power cable or adapter can easily prevent your Mac from charging.
Steps to check the power adapter and cable:
Inspect the charging cable for visible signs of damage, such as fraying or exposed wires.
Make sure the power brick is securely plugged into the cable and the outlet.
Try using a different power adapter and cable if you have one available.
If possible, test your current adapter on a different Mac to see if it works.
Example Error Message:
If you see an error message like "Charging is not supported with this accessory", this could indicate that the cable or adapter isn’t compatible with your Mac or is damaged.
Insight: Using a third-party, non-certified charging cable or adapter could cause charging issues. Always use Apple-certified cables and adapters to avoid compatibility issues.
2. Inspect the Charging Port for Dirt or Debris
Your Mac’s charging port may accumulate dust or debris over time, which can prevent the charging cable from making a solid connection. A dirty port can cause intermittent charging or no charging at all.
Steps to clean the charging port:
Power off your Mac and unplug it from any power source.
Use a soft, lint-free cloth or a can of compressed air to gently clean the charging port.
Avoid inserting anything into the port that might cause damage.
Insight: A clean charging port ensures a better connection and may resolve charging issues caused by dirt and debris.
3. Reset the SMC (System Management Controller)
The SMC is responsible for managing power functions on your Mac, including battery management and charging. Resetting the SMC can help resolve charging issues related to system bugs or hardware malfunctions.
Steps to reset the SMC:
For MacBooks with a T2 chip:
Shut down your MacBook.
Press and hold the power button for 10 seconds, then release it.
Turn your MacBook back on.
For other MacBooks (without T2 chip):
Shut down your MacBook.
Press and hold Shift + Control + Option on the left side of the keyboard, then press the power button for 10 seconds.
Release all keys and turn your MacBook back on.
Insight: Resetting the SMC is a common fix for various power-related issues, including charging problems. It won’t affect your data, so it’s safe to perform.
4. Check Battery Health
If your MacBook's battery is old or nearing the end of its lifespan, it may no longer be able to hold a charge properly. MacBooks typically start showing battery issues after a few hundred charge cycles.
How to check battery health:
Hold down the Option key and click the Apple logo in the top-left corner.
Select System Information.
Under Hardware, click Power and look for the Battery Information section.
Check the Condition field:
Normal: Battery is in good condition.
Replace Soon or Replace Now: Battery health is declining and may need replacement.
Example Error Message:
If you see “Service Battery” in the Battery Condition field, it means your battery is failing, and you should consider getting it replaced.
Insight: If your Mac’s battery is near the end of its life, you might notice charging issues or poor battery performance. In this case, replacing the battery could resolve the problem.
5. Check the Power Source
If your Mac isn’t charging, the issue could be with the power source you’re using. Sometimes, the power strip, outlet, or surge protector might be the problem.
Steps to check the power source:
Plug your Mac directly into a different wall outlet (bypass any power strips or surge protectors).
Ensure the outlet has power by testing it with another device.
If you’re using a power strip or surge protector, try plugging your Mac directly into the wall.
Insight: A malfunctioning power source could prevent your Mac from charging, so it’s important to test your outlet before assuming the problem lies with the Mac or its charger.
6. Update macOS
Sometimes, software bugs can prevent the battery from charging properly. macOS updates often include fixes for power-related issues, so it’s important to keep your Mac updated.
Steps to update macOS:
Go to the Apple logo and select System Preferences.
Choose Software Update and install any available updates.
Insight: Keeping macOS updated ensures you get the latest bug fixes, performance improvements, and compatibility updates for charging-related issues.
7. Perform a PRAM Reset
If your Mac is still not charging correctly after trying the steps above, resetting the PRAM (Parameter RAM) can help resolve hardware-related issues.
How to reset PRAM:
Shut down your Mac.
Turn it on and immediately press and hold Option + Command + P + R for about 20 seconds.
Release the keys and let your Mac restart.
Insight: Resetting PRAM can clear out corrupted system preferences and resolve issues with various hardware components, including the battery and charging system.
