Macbook pro screen does not turn on. Video: Apple MacBook does not work. MacBook won't turn on - what to do

The most common complaint when contacting a service center with a MacBook is that it won't turn on. If you haven’t spilled anything on it, haven’t noticed any “popping” noises when using it, and don’t smell a burning smell, there’s no need to rush to a repair service. There are ways that can help correct this situation, of course, if it is not a mechanical failure.

What to do if you can’t turn on your MacBook? First, stop panicking. The first step is to understand the concept of “does not turn on”. This means that when you press the power key there is no reaction from the laptop. Users often confuse this concept with the absence of an image on the screen or the absence of loading. Due to the lack of clues in the form of burning diodes, you can judge whether the device is turned on by the operation of the fan. The system's greeting sound can be considered the identifier that turns on.

Why won't my MacBook Pro or MacBook Air turn on?

The simplest breakdown in such a situation may not be the air at all, but the power supply. When the charger breaks, you won’t be able to charge the laptop, and when it’s completely discharged, it won’t turn on. Try connecting another power supply and after a short period of time try to turn on the device.

Keyboard

On Apple laptops, the power key is one of the keyboard buttons. The serviceability of the keyboard determines the serviceability of this button. A frequent breakdown of this key is that liquid gets into it and further short-circuits. The button is energized even when the gadget is turned off, so even a small amount of liquid will be enough.

Discharge or failure

If the laptop is completely discharged, then in order to turn it on, it is necessary for it to stand for some time on recharging to replenish the minimum level of energy in the battery. If the problem is a power failure (the indicator does not light up when connected to power), you need to temporarily disconnect the battery. Then connect the battery again. If the laptop boots, the problem is solved.

The lack of power may be due to a faulty MagSafe connector. If you suspect that this may be the reason why the laptop may not turn on, contact a service center.

Spilled liquid

Moisture getting inside the product leads to short circuits and oxidation of the contacts. As a result, not only the keyboard, but also the motherboard. If you spill something on the device, unplug it and immediately take it to a repair service.

Screen

If you can hear that the laptop is booting (you can hear the system welcome sound, the noise of the fan), but there is no display on the display, most likely there is a problem with it or with the video card. If you doubt that the fan is working, press the "CAPS LOCK" key - if it lights up, it means there is a problem with the display.

Part burned out

This part is most often the motherboard, due to the fact that about ten different voltages are supplied to it. In addition to this, the chipset and microcontroller can also often fail. You can suspect such a malfunction after eliminating the above-described breakdowns.

Diagnosis at home

Without special tools, it is difficult to diagnose at home. But you can check the battery discharge and the serviceability of the “power” key. To remove the cover you will need a regular screwdriver. To check the button, you need to remove the cover from the battery using a screwdriver. Then disconnect the battery. Separate the keyboard cable and connect the charging device. This method works for models from 2011.

In a situation where the battery is completely dead, you must also remove the cover and remove the battery. Then connect the device to charge. The laptop should turn on from the unit. Often this procedure can be avoided by resetting the SMC settings. This reset must be done before you begin disassembly.

System Multi-Controller (SMC)

The multicontroller provides power to all connections on the board. Switching on and modes are provided by SMC . It works even with the laptop turned off. The multicontroller is equipped with its own firmware and has a memory reserve where settings are stored. Failures of this program lead to various “glitches”. To eliminate these failures, you need to reset the settings to the original ones. You can do this in two ways:

If the methods described above did not help you, and you still do not understand why the device does not turn on, take the gadget and take it to an authorized repair center for diagnostics and further repairs. For residents of large cities, for example, Moscow, finding such a service will not be difficult.

Each manufacturer tries to make their device as modern, convenient and compact as possible. But unfortunately, it is very difficult to avoid breakdowns and defects. Apple appliances was no exception. The Apple company from Cupertino has created an ultra-thin and powerful laptop. And according to tradition, Apple decided to call its new product original name. MacBook is reliable computer, but unfortunately it may fail. A laptop can break down, both technically and software-wise. We will look at various options for breakdowns and consider various ways way out of a difficult situation.

Instructions for restoring the operation of a MacBook

So let's look at the following diagram:

1. Let's say your laptop won't turn on. First of all, turn off everything additional devices connected to MacBook.
2. Of course, the MacBook must be turned off. First, unplug the compact power cord from the computer and from the network. You need to wait about a minute. Now we connect an ordinary device first to the network, and then to the MacBook itself. The indicator should light green or yellow after connection.
3. If with network adapter and everything is in order with the cable itself, the indicator will light up. If there are any problems with the power supply, the adapter will not light up. In this case, the laptop does not turn on due to faulty parts. You need to contact an Apple service center.
4. So, if there are no problems with the network, and the equipment has started, but the main boot stage does not complete, then reset P RAM. This is done by simultaneously pressing the “Option”, “Command”, “R”, “P” keys and hold them until you hear the desired signal.
5. Now you need to reset the power management settings. This is done as follows: first we connect the power adapter to a working power source. Now press the key combination “Option + Control + Shift” and at the same time press the MacBook’s power button. Count down 5 seconds, and then press the power key again. After this, the MacBook should turn on while the boot process is in progress, check the indicator sleep mode- if it blinks, it means the boot cycle is complete.

These steps should help you get the settings up and running. If these operations do not help turn on the MacBook, then only the service center remains. If you managed to turn on your MacBook, then your computer has crashed. Perhaps this happened due to a sudden voltage drop, a sudden shutdown of the laptop in a hurry, or some kind of software glitch, etc. We also have an article describing what to do if you can't turn off your MacBook.

Unfortunately, any computer user may encounter a problem when operating system Mac won't boot and seems to freeze during the loading process. It usually looks like this: the computer starts to boot, the Apple logo appears on the screen as usual, but then nothing happens - the system does not boot, and the computer does nothing but forced shutdown The power button does not respond. In other cases, a loading indicator may appear under the Apple logo (similar to the one shown in the image above), but then nothing happens. Why does this happen and how can you fight it? Is it required in such cases? Let's figure it out in order.

Why Mac won't boot and freezes at the Apple logo

The reasons why the Mac stopped booting can be different:

• Operating system failure due to damage to important system files(for example, in case of incorrect installation of a system component update, or installation of a new OS).
• Damage to system files due to malware.
• Absence free space on the computer's boot volume.
• Inability to detect the boot volume due to a software error or cable damage hard drive(a clear symptom of this is).
• Malfunction of hardware components (damage to the hard drive or SSD, defective video chip, etc.).

Mac won't boot and freezes. What to do?

Depending on the reasons for the problem, there are different variations of its solution. Some you can try to implement yourself, while others can only be implemented by a specialist at a service center. Below we will give some recommendations on what you can do if your Mac stops booting and freezes on Apple logo or loading indicator. Let's start with something simple.

Boot in Safe Mode

Few people know that the operating room Mac system OS allows you to boot into safe mode (Safe mode), which allows us to identify various software errors systems. IN Safe mode mode only the system kernel with the main important functions, while booting the computer in safe mode, the file system is checked for errors and, if possible, eliminated. Therefore, in most mild cases, booting your Mac into Safe Mode followed by a graceful soft reboot may solve the problem if your Mac won't boot and freezes.

In order to boot a Mac (it doesn't matter whether it's a MacBook, iMac or Mac Mini) in safe mode, it is necessary When you turn on the computer, hold down the "Shift" key on the keyboard and hold until the loading indicator bar appears. Please note that loading macOS in safe mode takes significantly longer than standard operating system loading, so we recommend being patient.

Correcting Errors Using Disk Utility

Disk Utility is a specialized application for working with the boot volume and file system MacOS, which allows, in addition to the standard functions of formatting or partitioning a disk, to check the disk and boot partition for errors and correct access rights to system files.

To run Disk Utility if your computer won't boot normally, you need to boot from the built-in MacOS recovery partition. For this it is necessary When you turn on the computer, press the Alt/Option (⌥) button and hold it until the boot partition selection screen appears, then select the Recovery partition. Force booting from MacOS recovery partition can be done by pressing a keyboard shortcut Command (⌘)-R when you start the computer.

When the recovery partition is launched, you need to select "Disk Utility":

In Disk Utility, select the "First Aid" section and click "Run" (available for MacOS versions El Capitan and Sierra), or manually select "Check Disk" and "Check Permissions" (available for OS X Yosemite and older). If at the end of the process disk utility will report that the disk is good or restored, then try restarting the computer and check the loading of the operating system again. In case of successful correction of the found MacOS errors should boot correctly in normal mode.

If, during the verification process, the disk utility displays an error message that cannot be corrected, you should think about how to save important files and documents, and then reinstall the operating system.

Reinstalling the MacOS operating system

If your Mac won't boot and is stuck at the loading indicator, and recovery regular means does not give results, then, most likely, it will hardly be possible to do without reinstalling the operating system. At the same time, given the fact that the computer does not boot, retrieving the user’s files and documents can be very problematic.

To extract files from a boot volume that can't start, you'll either need to connect your computer to another Mac in external drive(the method is not very simple and requires a second Mac computer, FireWire or Thunderbolth cable, and strict compliance Mac versions OS on both computers), or connect to a computer with external media with an installed operating system, or a special software to extract and transfer data.

Unfortunately, not every Mac user has the opportunity to carry out such manipulations and, faced with a situation where their computer stops loading correctly and freezes, and simple ways solutions to the problem do not help, they simply do not know what to do. If your MacBook Pro, MacBook Air or iMac does not boot or the operating system freezes when loading, you can always turn to our specialists for help service center. will be carried out as quickly as possible, taking into account all your wishes about saving important data and the desired settings that our employees will make for your computer so that it pleases its stable work still very for a long time.

I have exactly the same problem - my Mac won't boot and freezes at the Apple logo
It hangs on the apple for a long time, then a chamomile appears, starts spinning, and so on ad infinitum.
I have important data there and I'm afraid of losing it. Can you restore both the data and the functionality of my MacBook?

• Hello Alexander!
  Sometimes, such problems are associated with the physical death of the hard drive on your Macbook. Unfortunately, hard drives On MacBooks they fail and not as rarely as we would like. If this is your situation, then we will need to separately remove the data that can be saved. After that buy new hard disk, install it, and return all saved data back, after installing the system.
  The cost of such a service is agreed upon with the client, after a thorough diagnosis for hard damage disk.

If suddenly, no matter what you do, your MacBook does not turn on, there is no need to rush to the service center. It’s quite possible to try to “reanimate” him at home - typical problems are known and are quite easy to fix. The only exceptions are mechanical damage and flooding with any liquid, be it plain water, chemical liquid, alcohol or a sweet drink.

Another reason to immediately contact the service is the smell of burning and cotton.

Most often, the charger and power connector, the controller are affected, less often - a short circuit and system error. The rarest but most severe case is a crack in motherboard or hard drive.

Eliminating display malfunction

First of all, you need to check the screen - perhaps the computer itself is fine, but there is a problem with the display.

How to check this:

• When you press the power button, you can hear the noise of the fan and disk drives;
• after pressing the power button, the melody of loading the OS is heard;
• if there are power/sleep indicators, they light up accordingly;
• if you press Caps Lock, the corresponding indicator will light up.

In this case, you need to check the operation of the display in accordance with the instructions on the Apple website or contact a service center.

Eating problems

What happens more often is that the MacBook stops turning on due to power problems.

If the computer does not turn on, then here is a simple check algorithm that needs to be performed:

• Is the computer connected to a power outlet? Is the socket working? it's easy to check.
• Are the power cord and adapter connected? ordinary forgetfulness and loose connections may be the reason for the lack of charge;
• Is everything ok with the power cord? if you have a spare or analog charger, it makes sense to try charging the mac with it;
• Are there any accessories connected to the computer (printer, storage device, phone)? turn them off and try pressing the power button again;
• After pressing the power button, hold it for 10 seconds and then press it again.

If these simple steps didn't help, you'll have to figure out in more detail why the computer isn't working.

No power

Most often, the problem is very simple and lies precisely in nutrition. Malfunction of socket, source uninterruptible power supply, “pilot” happens most often.

To check this, it is enough to connect a known-good device to them, and it is best to simply reboot the uninterruptible power supply. If you are using an extension cord, it makes sense to try connecting the power cord directly to the outlet.

It is also worth remembering that excessive use of extension cords, tees, surge protectors and additional blocks increases the load on the home electrical network and can cause short circuit.

Charging does not work

Sometimes the reason lies in charger. Kinks and pinching due to strong bending of the wire or pressing it, for example, by a door, render the power cord unusable. The most vulnerable places: bends of the cord, connection to the adapter, at the plug.

If everything is intact during a visual inspection, you should try to clean the connector from dust and at the same time check the integrity of the connector itself: bending or falling out of the plug means a complete malfunction of the power cord. This didn’t help either - it’s time to change the charger or go to a service center, they will definitely be able to diagnose the cause of the breakdown.

The battery has failed

If the computer is several years old, it may not turn on due to the fact that the battery life is exhausted. Usually it has an indicator that should light up while charging - if the charge is fully working, it makes sense to check this.

By the way, there are prerequisites for battery failure - too fast discharge V lately, discrepancy between the charge indicator data and the real operating time, and so on. In this case, the only way to fix your Mac is by replacing the used battery.

Reset settings

A special memory or controller error can also prevent your Mac from turning on. The fix is ​​simple, just a key combination and a reboot.

System Management Controller (SMC)

Sometimes the system management controller is to blame for the refusal to work; the situation can be corrected by resetting its parameters. To do this, with the power cord connected, you need to simultaneously press the combination “Shift” + “Control” + “Option” and the “Power” button. All buttons must be released simultaneously.

In this case, the light on the adapter either continues to light without blinking, or turns off - this is normal. After this reboot, you can turn on the computer.

PRAM and NVRAM (whatevertheyare)

A special section of PRAM/NVRAM can also create a power-incompatible error.

What to do then?

1. press the “power” button;
2. press and hold the “command” + “option” + “p” + “r” buttons until the gray screen turns on;
3. hold the buttons throughout the reboot and until the mac emits the boot tone again;
4. release the buttons.

Power Manager

If an error occurs during power supply (not safe shutdown, emergency shutdown, short circuit), “Power Manager”, which does not allow you to turn on the Mac, can also be rebooted.

• first remove the battery;
• press the “power” button;
• wait a couple of seconds, release;
• insert the battery back;
• Press the “Power” button again. The computer should start booting.

Other reasons

There are many reasons why a MacBook won't turn on. This could be damage to the power supply circuit, soldering of the board, or simply the fact that it is clogged with dust and overheats. Even an incorrect shutdown can make subsequent startup almost impossible. But usually everything is much simpler.

Separately, it should be said about the loading error after the update - in this case, the MacBook turns on, but only until the gray screen or the loading screen does not complete.

MacBook won't turn on after update

If the computer has not been updated for a long time, and then you had to install fresh upgrades on old version The OS or MacBook may not turn on or turn on but not boot.

Photo: gray screen during “eternal” loading

In this case, it is best to boot into safe mode - to do this, just turn on the Mac while holding down the “Shift” button. Didn't work out? Then you will have to format the data using special utility, instructions for its use can be found on the official Apple website.

MacBook overheated

If the computer is several years old or it’s hot outside, then it’s not surprising that it refuses to turn on. Most likely it overheated.

If the computer is new, just let it cool down. Under no circumstances should you apply cold objects to it or place it in a cold room; this can cause microcracks in the circuit boards due to temperature changes. After a couple of hours at room temperature, you can try to start it again.

If it is at least a year old, it makes sense to take care of cleaning it. You can do this yourself, if you have the necessary skills, or at a service center. But while the computer is under warranty, it can only be disassembled by a warranty service, otherwise free service will be impossible. Routine cleaning to prevent such problems is carried out at least once a year.

There are connected devices

An abundance of connected devices can be powered by Mac battery, preventing it from turning on. These are smartphones, tablets, external hard drive, flash drives, external Bluetooth modules, webcam, printers and other accessories.

There may also be errors in their operation that affect the launch. It's easy to check - turn off everything unnecessary and start the computer.

We do a forced reboot

If the computer shows at least some signs of life, you can try to force a reboot.

To do this, when connecting Magsafe power you need:

1. press the combination “shiftt” + “control” + “option” / “alt” + “power”.
2. if it's an old mac then use the combination "control" + "enter".

Faulty north or south bridge

If the MacBook regularly overheats, then it may not turn on due to damage to the bridge - this is the controller on the motherboard. There are two of them, they are connected to the board by buses, and the northern one is directly connected to the processor. Damage to any of them requires a mandatory service call.

Only diagnostics by a specialist and replacement of the affected part will help here.

RAM module not installed correctly

If there was an OP upgrade before the problem, then perhaps the module was installed incorrectly. To check this, simply pull it out and reinsert it, checking the instructions. Didn't help? Then return the old module as the new one may be faulty or incompatible. After this replacement, the Mac should turn on.

The reason why your MacBook won't turn on could be due to a variety of problems. It is best to find out what preceded the breakdown: unsafe shutdown, complete discharge, overheating, physical breakdown or bay.

Even if everything seemed fine outwardly, it is better to ask your family or colleagues if they touched the computer, if there was a power outage, or if there was a strange smell. Depending on this, they apply different ways restoration of work.

The only exception is mechanical damage and liquid ingress.

In this case, you should not try to solve the problem yourself, but it is best to remove the battery and take the Mac to a service center as soon as possible. Sometimes repairs may not be necessary - regular cleaning may well return the MacBook to working condition.

Apple equipment is famous not only for its trendy design, but also for its build quality. But like any electronics, it can fail. And if fixing some breakdowns is the work of a specialist, then minor problems can be solved on your own. So, what to do if your Macbook won’t turn on?

Determining the cause of the malfunction

First of all, you need to inspect the laptop for visible damage. Special attention is needed pay attention to the power connector and charger— the green indicator on it should be lit when connected to the network. The connector itself, especially when using a “non-native” charger, may become deformed or become loose. If you have an alternative charger, try turning on your Macbook using it.

The main reasons why a Macbook may not turn on is physical damage or a short circuit after liquid contact. Even if your equipment did not fall or fall under water, ask your family or colleagues. Perhaps they thought it would be okay and didn't tell you. In this case, it is better not to try to turn on the Mac again (if possible, remove the battery), but immediately go to a service center.

If there are no visible defects and the Macbook does not turn on after charging, the reason may lie in the controller.

What “symptoms” require you to immediately contact a service center?

• 1. If the Macbook stops turning on after a fall, impact, or sudden closing. In this case, a contact could come loose or a crack could develop along one of the boards. To determine the cause, you will need to conduct a diagnosis.
• 2. If the laptop has been flooded with liquid. Under no circumstances should you turn on the equipment if water, tea, juice or any other liquid has got into it - a short circuit may occur. The service center specialists will disassemble the Macbook, dry it, clean it and diagnose it. There may be no need for repairs.
• 3. If the last time you turned it on, you heard a pop or felt a specific smell. In this case it could happen short circuit on board. The exact cause can only be determined through diagnostics.

What you can try to do yourself

If you are sure that the Macbook did not fall or flood, then you can still try to turn it on.

• 1. Check that the charger is working properly. The indicator (green light) should light up when connected to the network and go out when disconnected.
• 2. Pull out battery(having previously disconnected from the charger) and press for a couple of seconds Power button. Replace the battery, connect the charger, and try turning on your Macbook again.
• 3. If the laptop is hot, wait for it to cool (this may take from half an hour to a couple of hours). After that, try turning on your Macbook again. If the equipment is working, you will need to clean it, for which you should contact the service center.

If none of the tips helped, it is better not to hesitate and turn to specialists. Remember that timely diagnosis and troubleshooting will help avoid more serious breakdowns, data loss and costly repairs. All the above actions apply to both macbook Air and macbook pro.
