MacBook won't charge. Faulty MacBook power supply

IN lately More and more often I am left with a half-dead laptop when I urgently need to go on business and work in field conditions. This is strange, because at such moments the MacBook Pro 2017 was “on a leash” and should show a confident 100%.

I started monitoring the charging during use and eventually realized that it was all the fault of USB-C, which showed itself to be a real g...

Today the charger falls out of USB-C at the wrong time

The problem turned out to be quite simple. Everything is fine with the USB-C cable, the port of the same format also works fine. But the first does not always hold up well in the second and constantly loses contact.

Guys, this is a failure! The photo above is real. In the situation on the left, everything is charging, but on the right, everything is no longer charged. In the picture it seems that the cable came out of the port by more than 1 mm, but in real life it was up to 0.5.

Why does the cable fly out of the port? This is due to the rather thick and relatively heavy 2 m USB-C cord.

In most cases, the socket is either close under the table or next to the sofa, and it is slightly suspended. I wouldn’t say that it’s directly under tension, but even minimal pressure is enough for it to fall out.

The cable comes out slightly from the port and charging stops. In hard work you don’t notice this, and then you find yourself at a brick with an inactive screen. It's terrible!

Of course, most often I have a ZMI 10 charging bank with me, so I can easily power my MacBook Pro, but it doesn’t always save me. It happens that she is discharged, and often she urgently needs to leave lightly, and she remains at home or in the office.

“This didn’t happen under Jobs” - this is certainly appropriate here!

Previously, the MagSafe wire fell out due to a reason...

Let's remember how it was before! Instead of a set of identical universal USB-C you had a separate MagSafe charging port. I used to consider it archaic, but today I remember it with special trepidation.

It was magnetic - this is its main feature. You just threw it at the port and it automatically connected to it. It was real magic.

In general, it had a magnet in order to quickly turn off if you caught it, so that your precious MacBook would not crash to the ground. But it also worked in reverse, he held charging cable in the charging port.

And that's not all.

...and showed active charging with backlight

MagSafe 2 could be plugged into the port on either side, and on each side it had a special indicator that showed the charging status.

If it glowed orange, you knew that the battery was being charged. If green, the battery is 100% full and can be turned off.

The main thing is that you would immediately see that charging did not start or stopped if contact was lost. In this case, the diode would not light up at all, but this almost never happened.

It’s also cool that you could monitor the charging process even with closed lid laptop. But now everything is different.

No, the socket itself has not stretched and the wire is fine

I have a MacBook Pro with Touch Bar, and on it 4 USB-C port, through which you can charge the device. But most often I use the top right one for this.

When I encountered loss of contact and stopping charging, I thought that the port had “stretched” or the cable had become pressed. But no.

I checked this cable on other ports, and then took another cord, and the situation did not change at all.

If the device does not move on the table, the problem hardly occurs. But admit it, did you really pay all these thousands of rubles to don't breathe on the laptop? I definitely bought it so that it would return every penny invested by thousands of percent, and it fails once again.

Overall, I'm delighted.

I know when charging has stopped by the screen brightness

To immediately understand that charging suddenly stopped, I enabled the option “Slightly dim the screen when on battery power” in the “ System Settings» > Energy Saving > Battery.

Now, when the cable loses contact, the screen brightness decreases noticeably. I see this and adjust the lace.

You can, of course, use your laptop more carefully so that the cable always remains in place. But no one will transplant my arms from the 5th point back to my shoulders, so I don’t see another real solution yet.

It seems it's time for Apple to remember its love for magnets

Apple could have easily sorted out my problem on hardware level. Enough for this do USB-C cable magnetic, and add a piece of iron to each port to which it would easily cling.

Considering that the company previously used a magnetic cable for charging, I don’t think that this would have become big problem purely technically or greatly influenced the price.

Apple uses magnets everywhere: smart covers for iPad, charging case for AirPods, magnetic charging for Apple Watch. It's time to bring them back to the MacBook.

If you have the same problem or you sympathize with my crookedness, be sure to like and write comments. And I’m finishing this article on the last %% of the battery, since it’s discharged again...

The decision of the Apple developers is striking in its simplicity and genius, because the decision to make MagSafe, that is, a magnetic line for charger it was risky. This is easy to use and pleasant because it saves you from awkward falls of your precious computer due to body movements. However, are there any disadvantages to this device? I would like to answer that no, but let's be honest - all MacBooks have problems from time to time and the gadget does not charge.

Simple causes and solutions to the problem

The first thing to check is the adapter itself. If he's not from Apple, but it’s a fake, then most likely it’s broken. It is worth remembering that original products always live longer than clones. The MacBook simply cannot charge if there is a problem with the adapter. Testing the adapter is not difficult on another device.

Now let's check the socket. It can also fail. If it works, but sparks when interacting, this is a bad sign. Sorry if the article is “captain’s”, but often people can’t even imagine that sockets also break. Another reason why the MacBook still won’t charge is incompatibility European plug with a Soviet socket. The plug may simply not fit into the holes provided for it.

Another reason is dust in the connector. If you often move or visit dusty places, then most likely all sorts of fine dirt often gets stuck in the connector. By removing it, you will resume the process. Of course, if the problem lies precisely in the garbage.

EU If both the adapter and the outlet work well, but the MacBook still won’t charge, then the problem lies in the device itself. Let's consider a situation in which the MacBook itself becomes the culprit. To solve systemic problems(even charger detection problems) you can use SMC - system management controller. More precisely, we need to reset its settings.

Solutions

First, turn off the MacBook. Now we connect the adapter. Press and hold the hotkey combination Shift+Control+Option+Power. You need to hold down the buttons for 2-5 seconds, this time, to delete the settings. Now turn on the computer. We connect the charger itself to the adapter and check it. Now, hopefully, the MacBook is charging. If all this does not help, then things are bad.

Complex problems

In the worst case scenario, your battery is dead. What to do? If you don’t understand anything about electronics, we advise you to take your MacBook for repair. If you yourself make the problem worse, it won’t get better, remember this. But if you practice repairs with your own hands, then further information is for you.

The battery is not charging and a breakdown has been detected in it. If you are sure, then you need to purchase a new battery. Please check its modification carefully when purchasing. We find thin or “watch” screwdrivers different types and let's begin.

Turn off the MacBook and close the lid. Turn the computer over and carefully unscrew the screws with a Phillips screwdriver. Be careful, such screws are very rare, so if you damage or lose one of them, you will have to work hard to find a replacement. You should also remember which side you unscrewed this or that screw. There will be 7 main short screws and 3 long ones, which are removed from the left side, in the area of ​​​​the plastic insert.

Without resistance, the lid of the case is removed and the “internal organs” appear before us. Pay attention to the battery. It is secured with three-bladed screws, which must be unscrewed with an appropriate screwdriver. You can disconnect the battery power with tweezers or, for example, a slotted screwdriver. But we recommend purchasing a specialized spatula for electronic devices. It is not only very convenient to use, but also will not harm the equipment.

Now there is a scary sticker left, after removing which you can remove the battery. Having replaced the element, we proceed to reassembly. Initially, use a spatula or tweezers to connect the power. After this, screw in the three-bladed screws that secure the battery. Don't forget to be careful. Install the bottom of the housing on rightful place, and carefully screw in the Phillips screws.

That's it, the process is completed. If all processes are carried out correctly, then the MacBook charges again. If it does not charge, then you should disassemble it again and check the connection of the battery to the power cord again. If your MacBook doesn't work, it's better to take it to a workshop. It is unlikely that you, without special skills, will be able to repair such a complex device.

Bottom line

Apple products have a number of weak points, for example, a weak “knee” on original headphones. It is difficult to say exactly how many there are and whether they are significant, but the fact remains that it is worth striving to correct them. A company with such a reputation cares very much about its citizens, so even the smallest details are worked out to the smallest details. However, the disadvantages that everyone talks about often go unnoticed.

Having considered simple problems and methods of solution, only one conclusion can be summed up. Look after your equipment, take care of it and it will repay you with a long and high-quality service. Forgetting about the most terrible enemy of computers, people do not attach importance to dust. And it slowly but surely gets clogged into all the recesses of the equipment, interfering with work and gradually killing the gadget. The MacBook is very delicate and requires a gentle attitude. Don't forget to keep an eye on him.

Hardly a technology pro was surprised by the description of the process of disassembling a laptop. However, perhaps it will help someone take the first steps on the path of development, because fixing a MacBook is not the limit. It is not known why such skills will be needed in the future, but we can definitely say that they will come in handy. After all, every day all branches of science are updated and the world is moving forward very quickly. Maybe in 10 years, in the countries of the former Soviet Union, automated living spaces controlled by remote controls will flourish. Or maybe it won’t prosper. But being prepared for anything is the main and main task.

Still, in the end, I would like to recommend acting in accordance with the guarantee. If the warranty on the poppy is active, you just need to contact a professional. He must do everything to the highest standard. But if it has expired, then you can delve into the insides and learn the technique. Please remember that the warranty does not cover your intervention inside the case. Even if you just broke a screw, no one is obliged to save the gadget. Especially Apple products It’s not cheap and experiments with it can backfire.

If your MacBook is not charging, it is very important to quickly respond to the problem. After all, the sooner you go to specialists for help, the greater the likelihood that the repair will take a minimum of time and cash. Remember, often after a certain period of use of a damaged laptop computer Apple MacBook you risk permanently disabling it, without the possibility of recovery.

The first thing we recommend that laptop owners do when they notice that the MacBook Pro is not charging is to make sure that the external power supply, that is, the charger, is working properly. You can perform similar actions yourself at home. And the likelihood of such a problem is quite high.

If it turns out that the charger is functioning properly, but the MacBook battery still does not charge, then we are waiting for you at our service center! Here is our qualified staff in as soon as possible will help you figure out why it's not charging MacBook laptop, and what causes this problem. This can be done thanks to professional diagnostics, which we provide to all clients absolutely free, using special modern equipment. Thus, the location of the damage will be quickly established and a decision will be made on the necessary restoration procedures.

The bulk of cases in which it does not charge MacBook Air, is divided into two categories.

• Problems with the MacBook mechanism.
• Battery failure.

Problems with the hardware itself

They can be of the following nature:

1. The connector is faulty. This component most often suffers from mechanical and physical impacts due to carelessness or when using a non-original charger. In this case, individual parts of the connector may break out, which leads to a similar problem - the MacBook has stopped charging. As a rule, to fix this problem you have to resort to replacing the faulty part.

2. The power management chip has failed. She is quite vulnerable to fire and blows. Sometimes even strong shocks can cause it to break.

3. Also, the MacBook often does not charge from the network due to problems in the power management circuit. Since this microcircuit has very complex design To find out which component has a failure, a short circuit or a broken contact, you can’t do without diagnostics.

4. The printed circuit board was damaged. Tracks could come off in it or microcracks could appear.

In any case, the MacBook will need to be diagnosed.

Battery problems:

If you still have a problem directly with the battery itself, then based on external signs you can assume the following.

1. If the battery is charging, but when you unplug the power cable the device turns off, you may have no contact between the battery and the laptop itself. It is also possible that some of its contacts are oxidized. Then you should clean them. It's also worth checking printed circuit board. It could cause tracks to break or microcracks to form.

2. When you hover over the Mac battery icon, laptop does not see it, most likely the reason is hidden in the battery itself or in the power circuit. The last part is also quite complex in design, so it is impossible to establish or refute this assumption without diagnostics.

In any case, no matter what happens to your MacBook Pro, MacBook Air, contact us! Our specialists will quickly and efficiently help you return your laptop to its previous reliable operation! All this is fast, profitable, convenient!

Continuing the topic of recommendations for troubleshooting problems related to charging Apple technology, raised by us in the article "", we present to your attention new material related to similar problems in MacBook users. And, although according to statistics, users of Apple computers encounter similar problems less often than iPhone users, due to the fact that MacBook won't charge and because of this the computer does not work, no one is insured.

Let's look at the main reasons why the MacBook stopped charging:

1. MacBook won't charge, power adapter is faulty

If your MacBook has stopped charging, you shouldn’t sound the alarm ahead of time and get ready to go to service center🙂 First, we recommend checking the serviceability of the MagSafe power adapter that you use for charging macbook. It is not uncommon for a power supply to fail due to mechanical damage or short circuit in the circuit and replacing it with a working adapter solves the problem.

If another power supply works and charges the battery, then you most likely just need to buy new adapter. It is worth noting that when purchasing, it is recommended to pay attention to the power, because... For different models Apple laptops need to use adapters of different power.

2. MacBook won't charge, cable is faulty

If your MacBook is not charging, you should pay attention to the condition of the wire. The MagSafe cable may be broken or the wire contacts may be damaged, which may cause the laptop to stop charging.

If we assume that the MacBook does not have any other damage, and the cable visually looks very “shabby”, the reason that the MacBook does not charge may be precisely this.

3. MacBook won't charge, MagSafe connector is damaged

Very often, mechanical damage or clogging of the MagSafe charger connector causes the MacBook to stop accepting a charge. This happens, as a rule, due to the appearance of oxides on the connector contacts, or when exposed to external factors. It is not uncommon for MagSafe to be damaged due to the use of low-quality power supplies - in such cases, the contact group receives electro-mechanical damage, which may be accompanied by blackening and even burning individual contacts MagSafe. Accordingly, as a result of this, the MacBook does not charge.

A simpler case is a clogged connector, in which, over time, particles of dust and fine dirt accumulate, which disrupts the physical interaction between the power supply cable connector and the contact area of ​​the connector. Carefully inspect the connector on the laptop - if it has any damage, we recommend contacting a service center for diagnostics.

4. MacBook won't charge due to battery failure

IN operating system OS X has built-in features to check battery capacity, condition, and maintenance needs. This allows you to anticipate battery problems before the MacBook stops accepting charge. This information is available in extended system information, which is located in the menu called up by clicking on Apple logo, located in the left top corner operating system desktop.

If trouble happens and the MacBook stops charging, it may very well be time to change the battery. Today, batteries for almost everyone MacBook models are available for order from a warehouse in St. Petersburg, so the replacement process in most cases is quite quick.

5. MacBook won't charge due to board failure

If your MacBook stops charging and the problem is not due to problems with the battery, connector, or software errors system management controller, there is a possibility of damage to the power circuit components on motherboard. By the way, such problems do not appear on their own - as a rule, in all cases there are certain reasons. Most often, this may be due to moisture, power surges during use of the charger, or mechanical damage to the computer.

In such cases, you need to contact a service center, where specialists can conduct technical diagnostics of the computer and offer a high-quality solution to the problem. Let us note that you should trust complex repairs of Apple laptop motherboards either to trusted technicians or to specialists from a specialized service center who have experience in complex repairs involving the restoration or replacement of components, and the service center itself must have special professional equipment necessary to carry out complex repair work.

The MagSafe power adapter in the MacBook is more convenient to use than similar solutions from PC manufacturers due to magnetic mount, which has already repeatedly saved my Mac from a visit to the service center. However, many owners of Apple computers may notice that sometimes MagSafe does not work entirely correctly - the adapter is connected to both the network and the laptop, but the device does not charge. Fortunately, there is a solution to this problem, although it consists of three stages.

Check the power supply

The most banal decision is often the most correct. It happens that the power adapter seems to be connected to the outlet, but for some reason refuses to work. In this case, it is necessary, first of all, to check the tightness of the contact and the power source, or better yet, try connecting it to a different outlet. This is especially true for household extension cords, with which MagSafe is not very willing to be friends.

Check the MagSafe port for foreign objects

Even an ordinary ball of dust can become an obstacle to successful charging your MacBook. At first glance, the adapter will be connected to the laptop, but the presence of a foreign object will prevent them from being in close contact for correct operation. Therefore, be sure to check the computer port and, just in case, free it from dirt and dust - for this it is best to use a regular toothpick, but not a needle.

Reboot SMC

If you have successfully completed the previous two steps, but the problem still remains, you will have to reboot the system management controller. For MacBook Air, Pro and Retina with fixed rechargeable batteries it's not at all difficult to do.

If after this MagSafe still refuses to charge your MacBook, then the problem is either in a damaged cable or directly in the motherboard of the computer itself. In this case, it is better to try connecting a different power adapter to the laptop and only then contact a service center.
