After cleaning, the imac does not soak in. It doesn’t work or macOS freezes when the Mac turns on, the apple burns and nothing happens. What is it timid? Correction of errors for additional disk utility

Golovna / Setting up

How many of you have a good feeling that Apple's operating system is famous for its reliability and the low number of bugs and glitches that occur during the work process. However, Mac OS, unfortunately, is not ideal and one miracle day we can’t just take it from anything else.

Without a doubt, this behavior of your Mac can be caused by a whole range of low-level consequences, which can be seen in different ways, as the author of this article is increasingly increasingly concerned with the situation, if The MacBook will not start up after a recent operating system update(Mac OS Sierra for this specific version) and he sees three loud squeaks, which are repeated with regularity

Unfortunately, this can happen to all of us, and going to a service center is often difficult and, obviously, not cheap. Luckily, there is a simple way to figure out where to take your Mac. Judging by the voices on foreign forums, a lot of people have helped to protect the money from being used for the service, having repeatedly helped such a “hint” and the author of this article. There is something new to talk about. So, why bother if your MacBook doesn’t fit in?

The appearance of mercy under the hour of obsession Mac

As was said earlier, in a similar way, a computer can be operated through a whole series of problems (at least 4, according to the data on the Apple website).

However, in our case, the sequence of actions and symptoms of the patient looks like this:

  1. you installed an update to the Mac OS operating system (or installed the computer itself, if you have auto-update enabled);
  2. when you turn on (restart) your MacBook, instead of turning on the operating system, you end up with a black (well, slightly gray, the backlight of the monitor still turns on) screen;
  3. While looking at this “light black” screen, you felt three trival sounds on the command “beep-beep-beep”, which were repeated at intervals of 5 seconds.

Having carefully visited the official Apple website, we know the symptoms and describe our problem:

"Three consecutive signals that are repeated with a five-second pause: the RAM has not passed the data integrity check."

Okay, that's clear, this is the RAM of our MacBook. And if they want any way, the government officials have forgotten about it. Ale mi yogo knew, and something simpler appeared. Of course, it’s not a fact that this method will help you 100%, don’t try Varto, because u bagatioh tse pratsyuє.

In fact, judging by discussions on foreign forums, the following MacBook models most often suffer from this problem and do not turn on: MacBook Air a1466, MacBook Pro a1278 and a1260. We are writing this article right from the very first.

The biggest problem is resetting SMC parameters

Ozhe, I am yours MacBook Air, MacBook Pro, iMac, Mac mini or Mac Pro won't turn on and eats- This signals a failure associated with random access memory (RAM), which can most often be reset by system management controller (SMC) parameters.

Depending on what device you have, stick to one of the lower algorithms.

If you have a MacBook with a dead battery

And most of the current models are like this, then the algorithm for you is as follows:


If you have a MacBook with a bad battery

Although, in my opinion, they haven’t been released for a long time, but about any episode - let’s face it:


Whether you have an iMac, Mac mini or Mac Pro

If you are one of the stationary computers from Apple, then resetting the system management controller (SMC) parameters is even simpler:


By fixing it in a way that is suitable for your Mac, you will be able to get started with Mac OS without any problems - this means that the problem is solved.

What does the SMC adjustment discount mean?

If you are not very familiar with computers or are simply familiar with such a procedure in the past, then before describing the whole thing, you may realize a completely reasonable question: “why don’t I waste important data or setup on my MacBook in results of the discount , and the procedure is often similar to "hard reset" on other gadgets?

We hasten to reassure you - no, you won’t waste anything important. If you really care, then take a look at the list of functions, as indicated by the system management controller (SMC), the parameters of which we reset:

  • reaction to pressing the life button;
  • reaction to opening and closing the display cover on Mac laptops;
  • drainage of battery resources;
  • keruvannya temperature;
  • rapt ruhu sensor;
  • ambient light sensor;
  • keyboard backlight;
  • I will become an indicator;
  • battery indicators;
  • Select an external (instead of the internal) video device for all iMac displays.

Alternative option - change the RAM

If you don't have a better option and your MacBook still won't start, you might want to try an alternative method. However, this is not true for any Mac computer, but only for low-end ones, the RAM can be replaced rather than soldered onto the motherboard (as is the case with most current Mac models).

If you have one of these computers, this option can really help you, you just need to know how to get to the RAM slot. The algorithm is very simple:


That's all. Now you know what you can try to work around if your Mac won't start and beeps with an unpleasant signal. We hope that one of the above options will help you solve this problem and save a significant amount of money on expenses to the service center.

How I spent the main working tool during the hour of travel.

Close to a month ago, I went a couple of days to Moscow to visit my relatives. And in all areas of my activity this is of no small importance, even if they are tied only to clear access to the extent that the director MacBook Pro 13''. There could have been problems with the Internet, but the laptop wouldn’t catch up on the regular train. I didn’t worry about him at all and even for nothing.

The very next day, near the capital, I lost my head of production.

My pleasure - be afraid of summer beaches and fence them off Mac like cold drinks.

Can you guess what happened to him? The guys from MacPlus, who pleased one local colleague, took this laptop for diagnostics, and immediately shared information on the drive of the five most popular Mac defects. Next, based on our understanding, we will recognize what problems summer (and not less) can bring.

1. Malfunction of the refrigeration system

People are often afraid of overheating, but what to expect when using your laptop:

Regardless of the cooling system MacBook significantly outperforms most competitors PC- It’s a decision, you still need to clean it once in a while. Otherwise, it is gradually hammered with brood and saw, as a result of which its productivity noticeably decreases over time.

The result is not a problem - serious overheating and failure of the motherboard elements is inevitable.

Infection can often occur immediately, so preventative work - cleaning the refrigeration system and replacing thermal paste - requires a minimum once per week

Of course, this indicator is truly individual and depends on where and how you work on your own Mac. As, for example, the laptop had been lying there for 5-7 months (though it’s hard to tell), the saw in the new one, for everything, would be much less than that of the same, but not actively vicorized.

On the right, what was drunk in the refrigeration system is consumed by its damp “wine”. The fan, blowing hot air from the body, instantly wets the middle of the saw from the excessive middle.

Once again, it is important that the indicators are individual - they lie in the minds of the robot, the waste and the laptop model as well. For example, a 15” MacBook Pro is much cheaper than the same MacBook Air.

Varto say okremo i about like thermal paste. Some types can easily smell up to 140 degrees, and in others they can reach low limit values, where the smell cannot cope with the atmosphere. When all the necessary heat is not added to the cooling system, some of it is lost “on the microcircuits”. With greater pressure, the temperature goes beyond safe limits, and the resource of this mode is exhausted more rapidly.

The drink itself, in certain situations, not only absorbs heat, but can also become a conductor of the flow (of course, this does not happen often, but it is still possible).

With thermal paste, everything is not so simple: it doesn’t always hang with fate. Everything depends on what you do: permanent work in Final Cut or gra in Call of Duty It is important to speed up the process, but rather to avoid the problem, it will solve the problem.

It’s still not easy to comply with the rules: I would like once a week You need to show your Mac to a specialist. If the wine is clean, I’ll tell you about it directly. If cleaning is required, right now the laptop will simply crash in the process of operation or galvanize, or even if you decide to turn on the power after cleaning, it’s definitely not good.

You can remove the cover and marvel at the camp of the device for a few seconds, and the axis of grace of the apparatus, which has already gone well, is much more complex. And more expensive.

2. Problems with exercise or life

It’s not so simple here, there are many options.

The battery died

Here you need to see two equal options. Either the battery has exhausted its resource and is not available for further use, or simply for any reason blocking by the charge controller. Of course, the MacBook won't turn on.

This publication has a rich diet. It’s just that it’s more obvious: the batteries in a Mac are very reliable, but not forever, and it’s too early to change them.

Practice shows that there is no doubt in the future. Of course, various utilities can be behind the battery, damaging the system itself. But it is always certain that the battery will fail for no apparent reason: long-standing and forgotten contact with water, unnoticed overheating or voltage drop, “fault” of an unclear charging device.

In certain situations, the attempt to charge the Mac may be recognized by the battery controller. physical problem. In this case, part of the circuit is specially displayed out of order - this is a dry mechanism. The battery itself may be fine, but the battery controller may be “dead” or unsafe for a MacBook.

Of course, in such situations repairs are possible, but it may be necessary to transfer the payment from the controller with the donor battery to the repair of their “service” for an additional programmer. This is not possible for all battery models, but in these cases, when it is realistic, the repair process can be equalized by replacing the entire battery. It will stay, obviously, where it is most reliable.

Vinikli problems with rose life

When using a laptop in a particularly hardcore mode MagSafe It can go wrong for a number of reasons - the contacts have oxidized, been covered with brood or worn out. As a result, the MacBook battery is discharged to zero and the laptop does not turn on without charging.

The situation with faulty MagSafe is not uncommon. You can blame any model, but most often it goes with the Unibody models of 2008-2012. These Macs are no longer released, but they are actively being used. As of 2012, health care providers must clean not only the refrigeration system, but also the surface of the outlets.

The MagSafe connector is permanently open and on the contact pad settles saw. There is often too much electricity from the electrical connection, and the connections are worn out from time to time. Ten parts of a millimeter are often enough to lose contact.

If the contact is frequently lost, the MagSafe board begins to heat up, the battery may go wrong (the system reacts as often as the charging device is connected/unplugged), and then the motherboard itself.

It is also necessary to understand, wisely, with clear power supplies. And keep the Mac itself clean.

The life block “crooked”

Another reason for the inability to charge a MacBook is a non-working power supply unit, which can go wrong for a variety of reasons: from the same voltage drops to banal wear.

In this case, a “working” Mac can completely recognize such a block. Over the years, charging performance will drop. In general, it is necessary for the system to “boil up” the power supply and show the status “battery is charging”, unless the laptop is turned on, which, I conclude, will no longer be possible to charge with such a unit.

The situation is the same as when charging MacBook Pro 15″ block view Air. The process is progressing, but much more, and since the battery has completely drained or “went to the point of death”, the required flow is of sufficient force.

The block must be selected carefully. On the right is not the tilki in the Yakosti Vikonnnya (at the Origіnal of the navigation of the factory garnish Zhist vid riznikh poshtepsyi situy), and the same to the parameter - the attempt is the struz of the BP Vidpovіdati to the Khimogamov laptop.

Vikoristovuvat tightening the charge is possible - but it’s safe, but the axle is weak (as they wrote earlier) - it’s not recommended. Most often, the Mac will simply charge completely (for example, if it is turned off and does not retain a charge itself).

If you work on a laptop connected to such a low-power unit, the system thinks that it is charging, but it is actually discharging, and the battery drains less from the power supply during the charging hour, drains less, and the indication on the icon Let's not talk about batteries. Pouch - the battery is worn out and out of order.

3. Serious voltage drop

Elements of the motherboard burned out

The worst thing that can happen when there is a voltage drop is that the elements of the motherboard go out of order. He is transferring a new replacement or expensive repair of the MacBook.

Such episodes will always be difficult. An entire element, or even just one element, “vibrates.” І result vidomy - Mac does not give a sign of life. With devices that have experienced a voltage surge, you need to be especially careful - problems may be ambiguous and may not appear immediately.

For example, you have a reference Mac, but discrete graphics do not work or do not integrate WiFi, if both the module and antennas are referenced.

The confirmation is not always on the surface, but renewal is very real, as, for example, when replacing a hard drive or other basic repairs. As a rule, such problems do not affect the durability of the devices. And as soon as they were put away, far away Mac work without problems.

The ones who suffer most often are the “cherry lances” - that’s what the plots are called, which are always under stress, no matter how small. The zone of rizik also has “power” elements that work under the great strums.

The battery is dead

Due to a large voltage difference, the MacBook battery will be destroyed, or it may “die” completely. This has already been talked about more.

The life block “died”

A voltage drop often becomes the cause of “death” to a life block, which goes wrong either often or not.

It is best to replace such a block, even if it is removed Mac- over there.

4. Great and trivale navantazhennya

The chipset or video chip burned out

MacBook You can rely on very great and trivial amenities, but only with a proper refrigeration system, such as regular cleaning. Otherwise, it will become very overheated, which will cause your death.

To put it more precisely, it is not only the chips themselves that can go wrong, but also the “binding” – the additional elements that distribute life on the microcircuits.

The video chip (also known as the graphics processor) is the main element, the “heart” of the video card. In today's Mac This chip is located on the motherboard.

The chipset is also part of the motherboard, and some models also include a graphics processor. Plus, the microcircuit contains many other important functions. However, if all the chips are intact, the problem may still appear.

If overheated, the contact may break BGA- the top of the crystal itself and the landing places on the lining of the chip (a mirror square and a square with a textolite with elements soldered onto it).

More often than not, in most cases the crystal lattice itself goes wrong. Temperature changes its structure and the chip facilitates replacement. In this case, the problem can be caused by heat shrinking of the chip, which allows you to frequently update the structure of the crystal mounts or rotate the crystal-lining contact.

However, as a rule, when the graphics go wrong, the chip needs to be replaced with a new one, and the technique itself serves more for diagnostic purposes.

It seems likely that it will happen sooner or later in case of changes, especially trivial ones. There are a lot of options here: you can “burn” the Mac from the gameplay, stop editing videos or render a great project.

A clean cooling system will help here, but it is also not omnipotent. Particularly foldable Mac cope with changes in Windows, adopt the latest versions (maybe also because there are more powerful games under this operating system, lower OS X).

5. The device was filled with liquid

Used keyboard

The keyboard is the first thing that suffers when it hits MacBook rіdini. In this case, you can get out of trouble either completely or often. As soon as the life button was activated, the laptop simply would not be able to get wet. Well, this may happen not immediately, but later after the incident.

Therefore, it is cheaper and more reliable to clearly follow the rules: Failure of a MacBook - go to the service center, as long as all is well, especially since diagnostics can be carried out without any problems in any event.

The keyboard is one of the most powerful places in Mac. Fill it in the easiest way. Often it hangs and flows, but in this case you may be in the risk group and may have a raptovo effect.

On the right is that in the keyboard itself there is a small lining on which the track extends to the skin key. The stench itself oxidizes. Technically, the keyboard can be repaired, but it will cost you a lot of labor and effort, but it will cost you as much as replacing it with a new one.

Often the backing of the keyboard “buries” everything else - a small number of moisture penetrating through the keyboard is affected by the backing (it is glued to the keyboard to stay strong and from the back side it is protected with a thick layer which way). This is exactly what happened with my Mac.

Short circuit on the motherboard

If you spent money on the motherboard, it can immediately experience a short circuit in about an hour. In this case, the fault is the oxidation of contacts.

Approximately 40-50% of the devices that are destroyed before repair are either flooded or flooded. Once again, I have the utmost respect for those who have already become a well-known fact: contact with hair will not pass without a trace, practical for a liquid device, unimportant, Mac tse, iPad or else iPhone.

Oxidation is almost always possible, especially if you do not physically connect the battery to the motherboard. It’s simply necessary to earn money, but most people with modern equipment are unlikely to have a screw on hand with such a machine Pentalobe, which almost all new people are victorious about Mac.

Simply plugging in the laptop is not enough, in which case everything is fed to the board, and the power that was spent on it acts as an electrolyte. When the battery comes out on its own, the electrolysis reaction starts, and its products appear on the fluid-conducting elements and tracks, and especially smaller components may be completely depleted in the process.

If you have no suspicions, or you know for sure that water has gone through everything, repairing your MacBook is not an option. I would like to recheck the requirements. Again, it’s better to play it safe, and get angry as soon as possible, if the damage is small, and even then, it’s easier to turn Mac to life.

Sometimes you have to update the tracks themselves. The water under the microcircuits is especially flexible. The stench is not hermetically sealed, but the microscopic gap is sufficient for water to penetrate there.

Cleaning in an ultrasonic bath in technical alcohol involves two steps - from a readily accessible place with a solution (water is important for pure alcohol), and ultrasound allows you to remove oxides from the surface.

Here it is also important to note that the water itself for electronics is not so dangerous, but unfortunately, perhaps everything that is lost in Mac– aggressive media – aerated water, kava, sweet tea, alcohol, etc. If the board is connected to a battery and a block, electrolysis proceeds much more rapidly, and it is practical to connect the battery at the same time.

Let's repeat it again. It’s important to note that immediately after an incident with your computer, it’s all right (at first glance), it’s still important to take a look at the technology, and even the problem may appear much later, if you already forget about what happened. And, as practice shows, it is much more convenient to update such laptops (and it will not be possible again).

All is well that will end well - that’s for sure

As it appeared, without my knowledge MacBook Pro poured chimos on the glass "Mojito" Flying onto the beach may be the reason. From the hull, the rіdina shvidko was wiped out, and she sank in the middle. Well, the keyboard contacts were oxidized, and the power button simply didn’t work. The keyboard was completely replaced and the laptop arrived. It’s good that the cocktail did not reach the mother’s pay.

While I was drinking kava and talking to the MacPlus specialists, they began to check the laptop and other problems that were not detected. Survived with little blood.

How have you been let down by your Mac?

PS: For those who have everything bad, we recommend replacing the battery ( 3.60 з 5, rated: 5 )

website How I spent the main working tool during the hour of travel. Close to a month ago, I went a couple of years to Moscow to visit my relatives. And in all areas of my activity, this would not be necessary, even if they are tied only to clear access to my beloved MacBook Pro 13''. There could be problems with the Internet, or...

What could be an unacceptable situation if the iMac doesn’t turn on at the most inopportune moment? In our time, there is probably not much left on computers. This unacceptable situation can be avoided. It is necessary to periodically clean the iMac (this can be done at any service center that specializes in post-warranty service for Apple products) and connect a voltage stabilizer (or th filter).

If such a situation occurs, do not rush to take your iMac to a service center. In certain situations, the problem can be solved independently.

If the iMac freezes (a very loud sound, the iMac sounds like it’s working), but cannot start up completely, then there is a problem with the software. Try speeding up the Time Machine program or enjoy the Safe Mode. Turn over the DVD drive; there may be a new disc that is important for starting the system. If any of these methods do not prove to be effective, then reinstalling the operating system is inevitable.

If the iMac does not turn on at all, check first to make sure that the problem is not in the socket or the cable (especially if there is a voltage cut - in this case the power supply may burn out). In another case, the breakdown occurred in the middle of the candy bar. The hard drive and RAM will go well. A possible and serious problem. No matter how bad you feel, you won’t be able to get any more sleep on your own. You need professional help.

Service centers, especially those that specialize in aimaks, often bring all-in-one PCs with the “iMac won’t turn on” problem. In such machines, experts for the treatment of illnesses often carry out diagnostics without any problems and identify the cause of the breakdown.

The selection of a service center must be done carefully. Focus on those that have the main spare parts in stock. In this case, iMac repair will be completed in the shortest possible time, and you will not be separated from your computer for a long time. When replacing spare parts, make sure they are original and not Chinese parts. Otherwise, in about a dozen hours you will have to go to the prison again.

Keep an eye on your iMac to reduce the risk of it breaking down. If you notice that you are not the same with him (becoming louder, humming, hanging up, raptly vibrating), then hurry up and show him to the professionals. This way, you can avoid serious damage and never say the phrase “My iMac won’t turn on.”

Why bother if Wi-Fi is not working? Easier to solve the problem
How to know if there is a problem? What makes it important for the adapter to work properly? Why doesn't Wi-Fi work on my laptop?

Well, your iMac is broken. Then you can now call a taxi http://taxi-dring.ru and take your digital equipment to the workshop for repair.
