Is your MacBook not charging or turning on?: Possible solutions

MacBook does not charge or turn on

When a MacBook won't charge or turn on, it's easy to panic, especially if you don't have a technical background. In the end, on that computer you keep documents, memories and programs that you need for your daily life and some of them may even become unrecoverable.

And the normal thing is to be tempted to take your computer to the technician you have on hand to see what may have happened. But if you are in these, be careful that you can still do something or another to avoid the trip and the bill.

In this article, we will explore in detail the steps you can take to diagnose and possibly resolve the issue of your MacBook not charging or turning on, which almost everyone will be able to follow regardless of their technical experience.

Check the Power Supply

If the equipment does not turn on, the first step is to check the power supply. And specifically, I would start with check power supply, as it could be the simplest and most common cause of the problem.

Within everything related to the source, there are three checks that you have to do to rule out a power problem:

Check the cable and adapter

Inspect the charging cable and power adapter, making sure there is no visible damage such as cuts, excessive bending, or discoloration that could give us the clue that there is some section of the cable that is not in the condition it is in.

This is very important to check, as a damaged cable may not be providing enough power to your MacBook and in this case, we would advise you to replace the power supply.

Try another plug

Has it ever happened to you that you plug something in and in a specific socket it doesn't work completely fine? Or does it only go wrong if you connect it to a specific power strip?

FOR rule out damage to the electrical installation or power strips, it doesn't hurt to plug your MacBook into different power outlets to rule out that the outlet where you connect the charger is defective.

Inspect the charging port

Your MacBook's charging port may be clogged by dust, lint or other debris that come together from day to day.

Use a flashlight to look inside the port and if you see something stuck, try to clean it carefully using a soft brush or compressed air, always making sure not to insert metal objects into the port, as this could damage the electrical contacts and equipment. irreversible form.

The SMC (System Management Controller) is a chip in your MacBook that manages many of the basic functions related to power and that may have been “cracked”, since it is a dependent piece of software after all.

If your MacBook does not respond when you connect the charger, restart the SMC can solve the problem and to do so, follow these steps:

  • Turn off your MacBook: Press and hold the power button for about 10 seconds until the machine turns off completely. Although if it doesn't turn on, you can skip this step.
  • Connect the charger: Make sure your MacBook is connected to power.
  • Press the Shift + Control + Option keys (left side of the keyboard) along with the power button: Keep all keys and the power button pressed for 10 seconds, as this combination is what activates the SMC reset.
  • Release all keys and the power button at the same time: Once you release them, press the power button again to turn on the MacBook. And if this already lights up the screen, let it charge until it is fully charged.

The battery: another culprit that causes your MacBook not to charge or turn on

Following the diagram of failures for electrical reasons, we have to check the charger pair: the equipment battery.

If your MacBook turns on only when connected to the charger, the problem could be with the battery, which usually have a limited life cycle, and over time can lose their ability to retain charge.

If you suspect this is the case, we do advise you to take your MacBook to an Apple Authorized Service Center to have the battery replaced.

In some models, the battery is glued to the chassis, so attempting to replace it yourself can be dangerous and can damage the computer if you do not have minimal technical skills. But if you dare, here is a post about how to change the battery on your MacBook.

Perform a Hardware Diagnostic

If you've tried all the steps above and your MacBook still won't turn on, The problem could be with an internal component more serious, like the logic board and here we would be facing a big problem.

In the event that you manage to turn on the MacBook, even if only temporarily, try to perform a hardware diagnosis with the brand's own tool, Apple Diagnostics.

To do this, restart your MacBook and as soon as it starts up, press and hold the "D" key. This will start Apple Diagnostics (for recent models) or Apple hardware test (for older models), which will allow us to launch tests that will tell us exactly what is wrong with your equipment.
