How to Fix Macbook Pro M1 Battery Issue 2022?

1. What exactly is the problem with the MacBook battery not charging?

In the event that your MacBook battery isn’t charging, it implies that you can turn it on yet the charger won’t charge the battery. All in all, your MacBook is generally functional, except for the battery charging capability. The accompanying side effects demonstrate that you have an accusing issue of your MacBook Air or MacBook Ace:

1. The message “Battery isn’t charging” shows up “in the status bar
2. The message “No battery accessible” shows up “in the status bar
3. There is no green or orange light on the MagSafe connector.
4. Your battery is typical and completely energized, as per the status menu. Notwithstanding, eliminating the charger makes the MacBook shut down right away.

Many individuals are confused by the expressions “MacBook battery not charging” and “MacBook not turning on.” In the event that you interface a functioning charger to a MacBook with a battery charging issue, it tends to be turned on. A “MacBook not turning on” issue, then again, implies that when you press the power button on the MacBook console, regardless of whether you have a functioning charger, you see nothing on the Macintosh screen, no toll, no light on the console, and no fan-turning commotion. As such, there is no evidence that something is going on under the surface on the MacBook.

2. Why is my Mac plugged in but not charging?

A charger, a battery, a charging circuit, and an SMC chip comprise the MacBook battery charging framework. If any of these components fails, the MacBook Air or MacBook Genius will not charge.

1. Charge with a MagSafe charger or a USB-C charger. It supplies energy to your MacBook and its battery.
2. Battery. It both stores and provides power (charging) (discharging).
3. Circuit for charging. It converts the charger voltage to power your Mac while also charging the battery.
4. System Management Supervisor (SMC). It regulates the charging circuit’s behaviour, including whether or not the battery is charged.

The majority of MacBook not charging issues are caused by faulty chargers, faulty batteries, and incorrect SMC data. Fortunately, these flaws are simple to correct. Faults in the charging circuit are difficult to repair, as we will see in the final section.

If the message Not Charging appears in the Battery Status menu and then disappears, your MacBook should be fine. There are several reasons why you might see the temporary Not Charging message:

You employ a low-power adapter:

The power adapter barely supplies enough power to keep your MacBook running, but not enough to charge the battery. For example, if you connect a Macbook Air charger (45W) to a 15″ MacBook Pro (85W charger required), you may receive a notification that the battery is not charging. When you turn off or sleep the Mac, the power adapter begins charging it.

Concern for safety:

If you connect your Mac to an airline power adapter, even if you turn it off or put it to sleep, the battery may not charge. You can continue to use your Mac without depleting its battery. Charging a battery in an aeroplane is considered a risky task for safety reasons.

Running high-performance applications:

If your Mac is running high-performance applications like video editing software or video games, the battery may be discharged. If the apps require more power than the adopter can supply, your Mac will use a combination of adopter and battery power to power the MacBook in order to meet the high power demand. This is a design feature developed by Apple to improve performance on demand. If the apps consume too much battery power, you may need to pause them and allow your Mac to begin charging the battery. If you turn off the Mac, the adapter will charge it much faster.

Increasing battery life:

Your battery may discharge to 90% or less before charging again. This is a design feature that helps your MacBook lithium-ion battery last longer. In the Energy Saver preferences, you can disable battery health management. We don’t recommend changing the setting unless you have a specific need.

3.How do I know if my MacBook battery is charging?

In request to rapidly analyze and fix the Macintosh battery not charging issue, you really want to know how a MacBook charges its battery. There are two sorts of MacBook chargers: MagSafe charger and USB-C charger. Apple stopped the MagSafe chargers in 2015-16.

MagSafe Charger

The result voltage of a MagSafe charger is fixed. A MacBook Air charger outputs14.5V. A MacBook Expert charger outputs16.5V, 18.5V or 20V relying upon the model.

At the point when you interface a MagSafe charger to the MacBook, the SMC will “handshake” with the data chip inside the Magsafe connector to recognize the charger type including voltage yield, current result, producer code, etc. Assuming the charger meets the models, the SMC turns on the go-ahead on the connector. This green light lets you know that the SMC has effectively distinguished a reasonable charger for your MacBook.

The SMC will likewise “handshake” with the data chip inside the battery to recognize the battery type including the functioning voltage, maker code, current temperature, etc. In view of the information got from the charger and the battery, SMC decides if to charge the battery and how much measure of current will apply to the battery cells. (How to Fix Macbook Pro M1 Battery Issue 2022)

SMC will tell the charging circuit to begin charging the battery assuming Every one of the accompanying circumstances are met:

1. The MagSafe charger has sufficient ability to turn on the MacBook and charge the battery simultaneously.
2. The temperature of the battery is typical and the battery isn’t completely energized.
3. The charging circuit recognizes NO over-current or over-temperature.

While the SMC controls the charging circuit to charge the battery, it turns on the orange light on the connector.The orange light lets you know that the charger is right now charging the battery.

4. How to Fix MacBook not charging problem step-by-step

Many factors could contribute to the MacBook battery not charging problem. The solution varies from simple to difficult depending on the cause of the MacBook Pro or MacBook Air not charging issue. We’ll start with the simple solutions and work our way up to the most difficult ones. Some hardware-related issues necessitate the use of specialised equipment and/or spare parts. At the start of each section, we will discuss the difficulty level of the fix as well as the equipment and (or) spare parts required for the repair. So, based on your skill, you can estimate your success rate. Best wishes!

4.1 Check charger output voltage

(Beginner level of difficulty) Required spare part: A spare charger will be useful.

If your MacBook charger isn’t working, it won’t be able to charge the battery. As a result, you must ensure that the charger is in good working order.

First, ensure that the power outlet is in good working order. You can connect a phone charger or a lamp to the power outlet, or you can connect your MagSafe charger to another power outlet. This simple step determines whether or not the power outlet is operational.

Don’t forget to double-check the charger’s power cord connection. The Apple adapter is made up of two parts: a MagSafe charger and a detachable power cord. Make sure the power cord is securely inserted into the MagSafe.

Next, carefully inspect the charger’s input and output cables, beginning at one end and working your way to the other. Keep an eye out for fraying or tears in the cable. This is most likely the source of any flaws similar to those mentioned. Replace the charger or try another charger that is available. These simple checks, believe it or not, frequently resolve the MacBook battery not charging issue.

When testing the MacBook with a spare charger, keep in mind that there are different types of MagSafe chargers for different models of Mac laptops. The output voltages for MacBook Airs are 14.5V, 16.5V and 18.5V for MacBook Pro, and 20V for the 15″ MacBook Pro with retina display. The general rule is that the higher-voltage (and thus higher-power) charger can take the place of the lower-voltage charger.

From 2008 to 2015, Apple used the same charging IC chip (ISL6259) on the logic board to handle different types of MagSafe chargers. This IC chip will generate the correct voltage to power your MacBook and charge the battery. As a result, using a higher-voltage charger will not harm your MacBook. Of course, when you buy a replacement charger, buy the same type  of of your original one.

in this way, the MagSafe 1 and MagSafe 2 chargers are not replaceable as the size of the connectors are marginally unique.(How to Fix Macbook Pro M1 Battery Issue 2022)

In the event that your MacBook utilizes Magsafe charger, as long as you could the green at any point light or orange light on the Magsafe connector, the MacBook charger is turned out great.

The MacBook USB-C charger is more astute. Your MacBook will naturally arrange a reasonable voltage yield (5V, 14.5V and 20V) from the USB-C charger. You don’t need to stress over the charger type, as long as the charger has the capacity to drive the MacBook.

In the event that your MacBook utilizes a USB-C charger, you can purchase a little USB-C power conveyance analyzer to screen the way of behaving of the USB-C charger displayed as beneath. It can give data including yield voltage, yield current and charger temperature. In the event that you get 14.5V from a MacBook Air USB-C charger or 20V from a MacBook Expert charger, the charger is turned out great. The photograph beneath shows the USB-C charger is conveying force of 20.3V and 0.20A to the MacBook Star.

4.2 Check charging port and Magsafe connector

(Beginner level of difficulty) No spare parts are required.

Examine the MacBook charging port and the MagSafe connector for debris and burned marks. The port and connector are held together by their strong magnetic attraction. Small metal objects, such as staples and paper clips, are drawn to the charging port. These foreign objects keep the connector from coming into direct contact with the charging port. Because of the extra resistor created by the loose contact, the connector may be very warm. In extreme cases, electric sparks can be seen. If you discover burn marks on the charging port or connector, clean or replace them as soon as possible before they cause further damage.

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

Pay close attention to the charging port’s middle pin. Check that no film is covering the pin. This pin is used by the SMC to communicate with the MagSafe charger. Any thin film will obstruct the electronic 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 small sharp knife, then finish with cotton buds soaked in 95% alcohol.

USB-C ports and plugs are also prone to contamination. You can clean them with cotton and alcohol. Before cleaning the connectors, remember to unplug the charger from the power outlet.

4.3  SMC chip reset

(Trouble level: Novice)

Spare part required: None

The Framework The executives Regulator (SMC) controls the course of MacBook battery charging. Assuming the SMC some way or another has erroneous information of the MagSafe charger or the MacBook battery, the charger will charge the battery gradually or even not charge by any means.

Macintosh began to involve non-removable batteries in all MacBook models from 2008. Follow these moves toward reset the SMC on a MacBook with non-removable battery:

1. Hold the power button for no less than 5 seconds until the MacBook switches off.
2. Associate the MagSafe charger, hold Shift-Control-Choice on the left-hand side console and the power button at the same time for 10 seconds.
3. Discharge all the keys.
4. Press the power button to turn on your Macintosh. Presently you have effectively reset the SMC.

Resetting the SMC on MacBooks with removable-batteries is basic.

1. Hold the power button for somewhere around 5 seconds until the MacBook switches off.
2. Eliminate the power connector and the battery from the MacBook.
3. Hold the power button key for 5 seconds to release any excess electric energy in the capacitors of the SMC circuit. On the other hand, you can hang tight for a couple of moments until the capacitors release normally.
4. Re-introduce the battery back to your MacBook. Presently you have effectively reset the SMC.
   If resetting the SMC can’t tackle your MacBook won’t charge issue, reset the PRAM as talked about underneath.

4.4 Reset non-volatile random-access memory (NVRAM)

Beginner level of difficulty

No spare parts are required.

NVRAM stores user-defined data like screen brightness, keyboard backlight settings, and sound volume. If this data is corrupted, your MacBook will not charge or will charge very slowly.

To reset the NVRAM, perform the following steps:

1. Keep the power button pressed for at least 5 seconds until the MacBook shuts down.
2. To turn on the MacBook, press the power button.
3. When you hear the chime or see any light on the screen, press Control-Option-R-P four times quickly until the MacBook restarts.
4. Let go of all four keys.
5. You have reset the NVRAM after rebooting.

If the MacBook is still not charging, proceed to the next level – hardware faults troubleshooting.

4.8 Examine a faulty DC-in Board Difficulty: Intermediate

MacBook Pro DC-in board spare part

A failed DC-IN board in the Pre 2013 Mac could be the cause of the MacBook Pro battery not charging. The SMC communicates with the MagSafe charger via the middle pin (pin 3). To protect the SMC circuit, a diode on the DC-IN board connects pin 3 to ground.

4.9 Repair or replace the faulty I/O board cable

Intermediate level of difficulty

MacBook I/O board cable replacement

A cable connects the logic board and the I/O board. To communicate with the MagSafe charger, the SMC employs a “one-wired” circuit. This “one-wired” signal must travel through the cable to the I/O board before reaching the charger.

It

If the cable is loose, the “one-wired” signal will not be transmitted to the charger, preventing you from seeing the green light on the charger connector and your MacBook from charging the battery.

Remove the cable and use a toothbrush and 95% alcohol to clean the cable and two connectors on the logic board and the I/O board. Keep the cable direction in mind. If you connect the reserved cable, you risk damaging the MacBook.

5. Understand the principle of MacBook battery charging circuit

We will look at some expert-level case studies. The key to success is fully comprehending the principle of the MacBook charging circuit. In this section, we will look at the MacBook Pro schematics 820-4924A. (How to Fix Macbook Pro M1 Battery Issue 2022)
