How to Fix the MacBook Pro Not Charging Green Light Problem

When your MacBook stops charging, all of a sudden, all your work plans are disturbed, and you have to reschedule your to-do list. Although there are many reasons that cause the MacBook Pro not charging green light error, you need to first detect the actual issue.

From faulty chargers to inaccurate SMC settings to damaged batteries, you need to check everything that is at fault. The problem might look tricky, but fixing it is easy as there are plenty of workaround methods you can try.

This article is your guide to fixing the battery not charging issue without spending much. Before you start, make sure you have a backup available handy so that you can restore data in case anything goes wrong.

Check Power Supply

When checking for a sufficient power supply, you need to examine various ports, connections, and outlets together. Make sure that the charger is in good condition and that there are no cuts in the wire. In addition, you can connect your laptop’s charger to another outlet to see if the charger is working.

At the same time, check that the power outlet is working properly. Plug in your smartphone charger and see if the phone is charging correctly. This will help you to ensure that the outlet is working perfectly. If the outlet is at fault, consider replacing it immediately. You may also need to ensure the proper functioning of the switch.

Tweak Battery Health Management Settings

On macOS Catalina and later versions, the battery health management is set to On by default. Before you plug in the charger of the MacBook for a subsequent charge, make sure that the battery is low and that only 10% to 15% of charge is available. Charging the batteries less often will increase the lifespan of lithium-ion batteries.

Turn off the Battery Health Management feature by navigating to System Preferences and clicking Energy Saver preferences. In macOS Big Sur or recent versions, you can see the “Charging on Hold” option on the Battery Status menu. Enabling this feature will delay your MacBook’s charging past 80%.

Examine All Power Ports and Connectors

Examine All Power Ports and Connectors

Whether or not you are facing any charging issues, you must examine the laptop ports regularly to ensure they are clean. Any kind of dust accumulation in the ports or connecting points can prevent the chargers from functioning properly. The charger may not connect appropriately due to the presence of tiny debris.

If you have pets at home, there might be hair stuck inside the port resulting in MacBook Pro not charging green light issues. Clean the ports immediately by using a soft brush and a cotton cloth. You may also use a can of compressed air to clean the ports thoroughly. Don’t forget to be gentle, though, or else you may end up damaging the ports permanently.

Identify the Loose Battery Connector

The pre-2016 MacBooks include nine-pin connectors that help connect the batteries to the logic board. All these pins are responsible for handling various functions where pin-6 detects the availability of the battery. On connecting the battery to the logic board, the pin signals the battery’s internal circuit to turn on the safety switch named MOSFET.

This results in the uninterrupted and safe flow of electric current in and out of the battery. Another benefit is that it prevents accidental shortening of terminals which can cause damage to the battery. Any kind of damage to the pin can be the reason for the quick battery drain. To check if this pin is working properly, you may need to visit the Apple repair center.

Examine I/O Cable for Damage

The input/output cable connects the I/O board to the logic board. The System Management Controller uses a single-wire circuit to interact with the MagSafe charger. The one-wired signal must go via the I/O board to reach the charger. In case the cable is loose, it will not allow the one-wired signal to pass to the charger.

Due to this, the green light on the charger will not blink, and as a result, the MacBook battery will not charge. To fix this, remove the cable, and then wipe the connectors and the I/O board using a cotton cloth or clean them with a soft brush. Take note of connections so that you can put them back appropriately, as reverse connections can damage the MacBook.

Replace Faulty or Puffed Batteries

Replace Faulty or Puffed Batteries

Any kind of inappropriate appearance of the batteries is an indication that they need to be replaced. If you see swollen or puffed batteries, remove them immediately and replace them with new ones. You will not be able to do that on your own, so consider visiting the Apple repair center to consult the technicians.

In this case, the Apple MacBook notification window will show “Replace Now” or “No Battery Available,” which indicates that the batteries are not in good condition. If you find that the batteries in your MacBook are puffed, but the battery notification window shows “Normal”, you must replace the batteries without a second thought to avoid any adverse effects.
