If you're reading this, chances are your MacBook Pro isn't charging correctly, and you're seeking answers to the problem. Take a break! It is not an uncommon problem, and various gadgets, including the iPhone, are affected.

We will address some of the feasible solutions to the problem here. But before we go into them, let's first get to the root of the issue and figure out why it happens in the first place.

So, Why Won't Your MacBook Pro Charge?

There might be several reasons why your MacBook Pro isn't charging correctly. For example, a worn-out or broken power adapter and cable might be the main reasons. An aging battery and certain other minor flaws may sometimes be equally responsible for the charging issue.

As a result, we will need to investigate the problem from several angles.

Check the charge port and Magsafe connector.

Examine the MacBook charging port and the MagSafe connector for debris and burnt marks. The port and connection are held connected by their strong magnetic attraction. Small metal objects like staples and paper clips are drawn to the charging port. These strange things keep the connection from directly contacting the charging port. The link may be pretty heated because of the additional resistance formed by the loose contact. In severe cases, electric sparks might be seen. If you see burn marks on the charging port or connector, clean or replace them as soon as possible before they cause more harm.

  • If debris is detected in the charging port, remove it with a toothpick or a pair of metal tweezers. No power voltage is present on the charging port's four power pins. The logic board's reverse-current safety gate (transistor) prevents battery power from being reversed to the port. You will not accidentally short the circuit by cleaning it with a metal.

  • Pay close attention to the charging port's center pin. Check that no film is covering the nail. The SMC uses this pin to communicate with the MagSafe charger. Any thin coating will obstruct the electrical transmission, and you will not see the green or orange light even if your MacBook and MagSafe are both operational. Clean the pins with a tiny sharp knife, then finish with cotton buds soaked in 95% alcohol.

  • USB-C ports and connectors are similarly prone to contamination. You may clean them with cloth and alcohol. Before cleaning the connections, remember to unplug the charger from the power outlet.

Does Your MacBook Pro Battery Need to Be Replaced?

When the battery is worn out, MacOS notifies you that it needs to be replaced. Click on the battery symbol in the menu bar to see if the battery needs to be replaced. If you see "Service Battery" or "Replace Now" on the menu, the battery has aged and can no longer retain a charge. The only remedy is to get the battery changed. This will give your MacBook a new lease of life.

Replace the faulty battery:

The SMC employs a pair of data lines known as the SM-bus to connect with the battery. SMC also uses current-sensing circuits to monitor the current flowing into and out of the battery in real-time. Your MacBook shows battery information in the alerts area based on this information.

There are five battery warnings:

  • Normal

  • Battery for Service

  • Replace Immediately

  • Replace Right Now

  • There is no battery available.

Apple's paper only specified the "Normal" and "Service Battery" messages, resulting in many misunderstandings and even deceptive information about the "Replace Soon" and "Replace Now" statements. These messages will be clarified here.

Normal: "Normal" indicates that your battery is working well. Your battery still has over 80% of its original capacity.

Service Battery: "Service Battery" refers to a battery degenerating to less than 80% of its original capacity. Typically, the battery can still last two or three hours. You have the option of replacing the battery, although it is not necessary. If you connect your MacBook to the charger most of the time to limit energy use, the battery may last a year or two.

Replace Soon: "Replace Soon" indicates that you must schedule a battery replacement soon. Apple has not established this message's requirements. According to our testing results, this notice means that your battery maintains less than 50% of its original capacity. If you continue to use the battery, keep an eye on it and make sure it is not swollen. A bloated battery in a 13" MacBook Pro is shown below—an overcharged battery strains the chassis, touchpad, and logic board.

If your touchpad splits or pops up, as illustrated in the image below, you probably have an enlarged battery. To avoid further damage, you must replace the battery immediately.

Replace Now: "Replace Now" indicates that the SMC can still communicate with the battery, but very little, if any, current can flow in or out of it. If you remove the charger, the MacBook will shut down immediately. The battery has finally reached the end of its useful life.

No Battery Available: "No Battery Available," as shown in the photo below, with a cross mark on the battery icon:

It signifies that the SMC cannot interact with the battery at all. Your battery is either entirely dead or improperly attached to the logic board. Changing the battery usually solves the problem. However, you may occasionally see the "No Battery Available" indication after replacing the battery. This symptom indicates that your logic board is malfunctioning. Fix your logic board to resolve the MacBook not charging issue.

If your battery fails, you can have it changed by a service provider or replace it 

yourself. When ordering the battery online, specify the battery model rather than the MacBook model to ensure you get the correct battery for your MacBook.

Remove the battery connector from the logic board with your fingernail or a plastic stick when replacing the MacBook battery yourself. Metal screwdrivers should never be used. By feeding the 12V battery power straight to the SMC, you risk short-circuiting the battery or, worse, destroying it.

Screws secure the battery to the MacBook casing in pre-2013 MacBook Pro and pre-2018 MacBook Air models. Unscrew the screws and unplug the battery connector from the logic board. When you buy new batteries online, most come with a handy screwdriver.

Apple decided to attach the batteries to the MacBook casing with MacBook Pros released after 2013 and MacBook Airs released after 2018. For beginners, removing the bonded battery from the MacBook casing is difficult. Take note of the specialized logic board. You don't want to ruin the logic board by knocking off specific chips.

In recent MacBooks with USB-C charging ports, the battery connection is changed. Power and data transmission cables are no longer connected to the same link. A flex cable connects the data lines to the logic board.

The precise method for removing this sort of battery is critical. First, remove the flex cable from the logic board. Then, unscrew the screw and disconnect the power connections with a T-5 screwdriver. When you disconnect the data flex connection, the intelligent battery turns off the "safety switch" within the storm, and there is no power on the power terminal.

MacBook batteries, made of lithium-ion, charge quickly and last long. However, the lifespan of your storm is partly determined by how well you care for it. For example, it's advisable not to keep your MacBook batteries uncharged for an extended time. Apple also includes several battery health management options that you should employ to maintain your MacBook battery healthy for as long as possible.
