Facing the issue of a Mac charger plugged in but not charging is a common frustration experienced by many Mac users. We’ll cover everything from issues with the charger itself to problems with the battery or software. Let’s dive in and find out why your Mac charger may not be charging as expected.
Inspecting charging and DC cables for damage
Feeling for Excessive Heat from the Charger
One of the first things to check when your Mac charger is plugged in but not charging is whether it’s overheating. To do this, gently touch the charger while it’s connected to your Mac. If it feels scalding, there may be an issue with the charger itself.
Examining charging cable for wear and tear
To troubleshoot why your Mac charger is plugged in but not charging, it’s essential to inspect the charging cable for any signs of wear and tear. Look closely at the entire length of the cable, checking for frayed or exposed wires. Damaged cables can prevent proper power transmission.
Checking DC cable connections for looseness or damage
Another potential issue could be loose or damaged connections in the DC cable. Ensure that both ends of the cable are securely plugged into their respective ports on your Mac and the power source. Loose connections can disrupt the flow of electricity and hinder charging.
Verifying that cables are securely connected to both the Mac and power source
Confirming a secure connection between your Mac and the power source is crucial. Sometimes, cables may appear connected but must be fully inserted into their ports. Gently push them in to ensure a snug fit on both ends.
Looking out for any visible signs of damage on the cables
Inspect the charging and DC cables for any visible signs of damage, such as bends, kinks, or dents. These physical damages can affect the flow of electricity and result in charging issues.

Ensuring Proper Voltage Input Based on Geographical Location
If you’re experiencing charging problems while traveling internationally, it could be due to voltage differences between countries. Some countries have different voltage standards, which may require you to use a voltage converter or an appropriate plug adapter when charging your Mac abroad. Make sure to research and understand the voltage requirements of the country you visit to avoid any charging complications.
Remember, using the correct power adapter that is compatible with your specific Mac model, ensuring proper wattage requirements are met, avoiding third-party chargers that may not be compatible, and considering voltage differences based on geographical location are all essential steps in resolving charging issues with your MacBook or MacBook Pro.
Troubleshooting faulty logic board and loose I/O board cable
Checking if the I/O Board Cable is Properly Connected
Another factor to consider when troubleshooting a Mac charger that’s not charging is the I/O (Input/Output) board cable. This cable connects the logic board to various components of your Mac, including the charging port. If it becomes loose or disconnected, it can disrupt the charging process.
You can check if the I/O board cable is connected correctly by opening up your Mac and inspecting its connection points. Ensure that it is securely plugged into the logic board and the I/O board. If you notice any looseness or disconnection, gently reattach it and test if this resolves the issue.
Seeking Professional Assistance if Logic Board Needs Repair or Replacement
If you have tried investigating both potential issues mentioned above but are still experiencing problems with your Mac charger not charging, it may be time to seek professional assistance. A certified technician will have the expertise to accurately diagnose and repair any hardware-related problems.
Considering Loose I/O Board Cable as a Possible Cause
Sometimes, a loose I/O board cable can cause your Mac charger not to be charging. If you have observed any looseness or disconnection during your inspection, reattaching it securely may solve the problem.
However, if none of these troubleshooting steps seem to fix the issue, it’s best to consult a professional technician specializing in Mac repairs. They will be able to diagnose and resolve any underlying hardware problems preventing your Mac from charging correctly.
Resetting SMC on newer Mac models
Explaining how to reset the System Management Controller (SMC)
To resolve the issue of a Mac charger being plugged in but not charging, one potential solution is to reset the System Management Controller (SMC). The SMC manages various hardware functions on your MacBook, including power management.
Outlining steps specific to newer Mac models
The process of resetting the SMC can vary depending on the model of your MacBook. For newer Mac models without a removable battery, follow these steps:
- Shut down your MacBook.
- Connect the MagSafe power adapter.
- Press and hold the Shift + Control + Option keys and the built-in keyboard’s power button.
- Release all keys and the power button at the same time.
- Press the power button again to turn on your MacBook.
For older Mac models with a removable battery, follow these steps instead:
- Shut down your MacBook.
- Disconnect the MagSafe power adapter.
- Remove the battery from your MacBook.
- Press and hold the power button for 5 seconds.
- Reinsert the battery and connect the MagSafe power adapter.
- Press the power button to turn on your MacBook.
Highlighting the benefits of resetting SMC in resolving charging issues
Resetting SMC can help resolve various charging-related issues by recalibrating specific hardware components that control power management functions. It can fix problems such as incorrect battery percentage readings or a charger not being recognized by your MacBook.
Emphasizing caution while performing SMC reset
While resetting SMC is generally safe and often resolves charging issues, it’s essential to exercise caution during this process:
- Ensure you follow instructions specific to your MacBook model to avoid unintended consequences.
- Ensure you have saved any unsaved work before initiating an SMC reset, which involves shutting down your MacBook.
- If the issue persists after resetting SMC, it may be necessary to seek further assistance from Apple Support or an authorized service provider.
Conclusion
In conclusion, if your Mac charger is plugged in but not charging, there are several potential causes to consider. First, check for any overheating or cable issues with the charger itself. Inspect the charging and DC cables for any visible damage or fraying that may affect the charging process. Ensure you use the correct power adapter for your Mac model.
