How to reset the SMC on Macbook Pro when it doesn’t charge

A Mac is a piece of electronic equipment with some of the best performance.

We are sure that if you also own a Mac, you have only had good results from it so far.

But there comes a time in the life of any device when it can start behaving strangely.

Now you might be wondering what we mean by “strangely.”

When we say that a Mac is starting to behave strangely, we mean that it can have any of the following problems:

  • Its screen resolution may begin to change its settings suddenly.
  • The fan in the device may start running randomly, and its speed may be set to a maximum value.
  • You cannot optimally charge the battery installed in the device.
  • The Bluetooth system may have connectivity issues.
  • The Wi-Fi system may be malfunctioning.

A quick solution to these operational problems can be represented by:

  • Stopping the applications that you are using when the issues arise.
  • Restarting the applications.

But what if you tried these two methods, but neither of them could fix the issues with your Mac?

In this case, you’re left with three options that you can try to eliminate the running issues that your device suffers from:

  • Reset PRAM.
  • Reset NRAM.
  • SMC reset.

By resetting them, there is a high probability that all the problems that your Mac suffers from will disappear.

To better understand why resetting them can be a solution to your problems, we need first to understand what these terms mean.

PRAM is a name that refers to the memory installed on your Mac whose primary purpose is to store basic details about your device.

This abbreviation comes from the name of parameter random access memory.

This memory stores essential information regarding the basic settings of your operating program.

Some of the settings that are stored in this memory are as follows:

  • Screen resolution settings.
  • Time settings.
  • Speaker volume settings.

All information about these settings stored in this memory is not stored there temporarily.

This information is not deleted after a certain period; it remains stored there for a long time.

This type of memory even has a small battery installed, used for operation while your device is turned off.

Because of this, the information is not deleted when your computer is turned off.

NRAM is another type of memory found in Intel Mac devices.

The role of this type of memory is very similar to that presented by PRAM.

NRAM stores information about the basic settings of your device so that it can be easily accessed when needed.

It is true that, unlike PRAM, NRAM has a lower predisposition to break down so quickly and so often.

But that doesn’t mean you don’t have to reset it from time to time to reduce its chances of malfunctioning in the future.

From a technical point of view, the steps you need to follow to reset the two types of memories are similar.

SMC is a type of chip found in any Intel Mac device.

The abbreviation for SMC comes from the name of system management controller.

The leading role of this type of chip is to take care of all the physical components presented by your Mac.

Some of the leading hardware functions that are under the control of this type of chip are the following:

  • The fans installed in the Mac deal with lowering its temperature.
  • Device status lights.
  • Overall system performance.
  • The power-up process of your battery.

Unlike SMC, PRAM and NRAM are more concerned with controlling the software features presented by the device.

Now that we know better what these technical terms mean and what roles each one presents, it’s time to move to the next question.

The time has come to ask yourself: If my Mac has problems charging its battery, what should I do?

What kind of components may have some malfunctions that may cause this problem of charging the device battery?

From the above, we can easily deduce that a failure of the SMC chip can most often be responsible for such a problem.

This is because SMC is responsible for controlling the hardware charging function of the device’s battery.

Now that we’ve figured out which component might be to blame for this problem, we still have to figure out how to fix it.

The best way to fix this malfunction is to reset the SMC chip.

An SMC reset can often fix this problem with your battery charging process.

But if you don’t know how to reset your SMC chip?

Do you have to give up this idea?

No, not at all.

Because we are here to help you and give you the best advice we have.

We will guide you carefully through all the steps you need to follow to perform an SMC reset in the best way.

The steps you need to take to perform this reset may differ depending on your model.

This article will show you the steps you need to follow to reset your SMC on a Macbook Pro.

But even with this model, the steps you need to take to reset your SMC can be influenced by the following:

  • The type of batteries it has.
  • The kind of security chip it has.

There are two types of devices:

  • Some have a set of removable batteries.
  • Some have a set of non-removable batteries.

Depending on the year of manufacture, there are two different types of devices:

  • Some were manufactured after 2018 and contained the Apple T2 security chip.
  • Some were manufactured before 2018 and did not contain the Apple T2 security chip.

Fortunately for you, we know what steps you need to take in each listed situation.

And to make sure you get the best results, we’ll show you the steps below.

If you have a Macbook Pro that was manufactured after 2018 and contains the Apple T2 security chip, follows these steps to reset its SMC:

How to reset the SMC on MacBook pro

5. After 10 seconds, release the buttons and turn on your Mac.

And if you have a Macbook Pro that has a set of removable batteries installed, we recommend that you follow these steps to reset your SMC:

1. Turn off your device.

2. Remove the battery installed in the device.

3. Press and hold the power button for 5 seconds.

4. Insert the battery back into the slot.

5. Restart your device.

Now that you’ve learned how to repair a Macbook Pro with battery charging issues, it’s time to dig deeper.

It’s time to find out what causes these battery charging issues.

Reasons your Macbook won’t turn on or charge

1. Make sure your Mac is connected to a power source.

You may connect your charging cable to a power source, but it may not be optimally connected to the device.

Try unplugging the charging cable and plugging it back in again.

2. Make sure the socket to which your Mac is connected is working.

You may plug the power cord into a defective power outlet.

Try changing the socket to which the charging cable is connected.

3. Check the power adapter.

Each power adapter that comes with a Mac has two main components:

  • A square-shaped part with a removable socket.
  • A charging cable.

Make sure that these components are optimally connected.

4. Check the status of the power adapter.

If you are using a worn power adapter with many malfunctions, that can be the leading cause of the charging problems.

A charging cable with tears or a discolored adapter may be the primary sign of wear.

The best solution for a used and defective power adapter is to purchase a new one.

5. Check the type of power adapter and charging cable used.

Using a power adapter or charging cable incompatible with your Mac can cause charging problems.

If it has a USB-C charging port, you’ll need to use a USB-C charging cable.

But some USB-C cables can’t be used to charge devices but only to transfer data.

That’s why it’s a good idea to check carefully and make sure you’re using the charging cable your device needs.

6. Check the power adapter temperature.

A power adapter that overheats often may not work optimally.

And a power adapter that can’t work optimally can’t power a device with the power it needs.

Therefore, it is recommended that you ensure that the power adapter you are using is not covered by any object that could cause it to overheat.

7. Check the power port.

If there is a large amount of dust inside the power port, this could be a cause of the charging problem.

Due to dust, the charging cable may have trouble connecting to the power port.

And if you cannot optimally connect the charging cable to the power port, the charging process may not proceed as it should.

It is essential to ensure that the power port is clean before inserting the charging cable.
