Macbook Air won't turn on what to do. What to do, macbook does not turn on. How to perform a factory reset on Macbook Pro and Macbook Air

Apple technology is famous not only for its trendy design, but also for its build quality. But, like any electronics, it can fail. And if the elimination of some breakdowns is the work of a specialist, then minor problems can be solved independently. So, what to do if Macbook does not turn on.

We determine the cause of the malfunction

First of all, you need to inspect the laptop for visible damage. Particular attention is needed give the power connector and charger- the green indicator on it should be lit when connected to the network. The connector itself, especially when using "non-native" charging, can be deformed or loosened. If you have an alternative charger, try turning on your Macbook using it.

Of the main reasons why a Macbook may not turn on is a physical breakdown or short circuit after liquid has entered. Even if your equipment did not fall or fall under water, ask your relatives or colleagues. Maybe they thought it would work out and didn't tell you. In this case, it is better not to try to turn on the poppy anymore (remove the battery if possible), but immediately go to a service center.

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

With what "symptoms" should you immediately contact the service center?

1. If the Macbook stopped turning on after being dropped, hit, or abruptly closed. In this case, any contact could move away or a crack could go along one of the boards. To determine the cause, it will be necessary to conduct a diagnosis.
2. If the laptop was flooded with liquid. In no case should you turn on the equipment if water, tea, juice or any other liquid gets into it - a short circuit may occur. The service center specialists will disassemble the Macbook, dry it, clean it and diagnose it. It may not need repairs.
3. If the last time you turned on you heard a pop or felt a specific smell. In this case it could happen circuit board. The exact cause can be determined only by resorting to diagnostics.

What can you 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 if the charger is working properly. The indicator (green light) should light up when connected to the network and go out when disconnected.
2. Remove the battery (having previously disconnected from charging) and hold down the Power button for a couple of seconds. 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 contact the service center.

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

macbook.appel~ marina ~ 02-11-2014

Turning on the screen lights up after a minute, a folder with a question mark appears in the middle, and the macbook itself does not turn on. Help me find out the reason

Macsave Center response: Good evening, there may be several problems with the lack of download, it may come out a loop hard drive out of order, myself HDD or maybe gone operating system Mac Os X. We need to make a diagnosis, perhaps with you.

If suddenly, no matter what you do, the MacBook does not turn on, it is not necessary to rush to the service center. It is quite possible to try to "reanimate" it at home - typical problems are known and fixing them is quite easy. The only exceptions are mechanical damage and flooding with any liquid, whether it be 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 the power connector, the controller suffer, less often - a short circuit and system error. The most rare but severe case is a crack in motherboard or hard drive.

Display Fault Exception

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

How it can be checked:

- when you press the power button, you hear the noise of the fan and the operation of disks;

- after pressing the power button, the OS boot melody is heard;

- if there are on / sleep indicators, they are lit with the corresponding light;

- 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 the service center.

Nutrition problems

Much more often it happens that the MacBook has stopped turning on due to power problems.

If the computer does not turn on, then here is a simple check algorithm that you need to perform:

- is the computer plugged in? is the socket correct? this is easy to check.

- Are the power cord and adapter connected? ordinary forgetfulness and a loose connection can be the cause of the lack of charge;

- is everything ok with the power cord? if you have a spare or analog charger, it makes sense to try to charge 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, then press it again.

If these simple steps did not help, you will have to understand in more detail why the computer is not working.

no power

Most often, the problem is very simple and lies precisely in nutrition. Malfunction of the socket, 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 just reboot the uninterruptible power supply. If you're using an extension cord, it's a good idea to try plugging the power cord directly into a wall outlet.

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

Charging not working

Sometimes the reason lies in the charger. Kinks and pinches due to a strong bend of the wire or pressing it, for example, with a door, make the power cord unusable. The most vulnerable places: the bends of the cord, connecting to the adapter, at the plug.

If everything is intact during a visual inspection, it is worth trying 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. It didn’t help either - it’s time to change the charger or to a service center, there it’s definitely possible 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 battery being depleted. battery - usually it has an indicator that should glow during charging - with a fully functional charge, it makes sense to check this.

By the way, there are prerequisites for a battery breakdown - too fast discharge lately, a discrepancy between the data of the charge indicator and the real time of operation, and so on. In this case, the only way to fix your Mac is to replace the used battery.

Reset options

An error in a special area of \u200b\u200bmemory or a controller can also prevent the 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, you can correct the situation by resetting its parameters. To do this, with the power cord connected, simultaneously press the combination "Shift" + "Control" + "Option" and the "Power" button. All buttons must be released at the same time.

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

PRAM and NVRAM (whatevertheyare)

A special area of PRAM/NVRAM memory can also create an incompatible error.

What to do then?

1. press the "power" button;

1. press and hold the "command" + "option" + "p" + "r" buttons until the gray screen turns on;

1. hold the buttons throughout the reboot and until the mac again emits a boot melody;

1. release the buttons.

power manager

If an error occurs while powering on (not safe shutdown, emergency shutdown, short circuit), Power Manager, which does not allow you to turn on your Mac, can also be restarted.

- first take out the battery;

- press the "power" button;

- wait a couple of seconds, let go;

- insert the battery back;

- press the "Power" button again. The computer should start downloading.

Other reasons

There are a lot of reasons why the macbook does not turn on. This may be damage to the power circuit, and soldering of the board, or simply that it is clogged with dust and overheated. Even an incorrect shutdown can make the subsequent inclusion almost impossible. But usually everything is much simpler.

Separately, it must be said about the boot error after the update - while the macbook turns on, but only to a gray screen or a boot screen that does not end.

MacBook won't turn on after update

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

In this case, it is best to boot in safe mode - to do this, just turn on the Mac while holding the "Shift" button. Did not work out? Then you will have to format the data using a special utility, instructions for using it can be found on the official Apple website.

MacBook overheated

If the computer is already several years old or it is hot outside, then there is nothing surprising in the fact that it refuses to turn on. He probably overheated.

If the computer is new, just let it cool down. In no case should you apply cold objects to it or put it in a cold room for this, this can provoke the appearance of microcracks in the boards due to temperature changes. After a couple of hours at room temperature, you can try to start it again.

If he is at least a year old, it makes sense to take care of his cleaning. You can do this yourself, if you have the necessary skills, or in a service center. But while the computer is under warranty, you can disassemble it only in the warranty service, otherwise free maintenance will be impossible. Regular 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 the Mac's battery, preventing it from turning on. These are smartphones, tablets, external hard drives, flash drives, external Bluetooth modules, webcams, printers and other accessories.

There may also be errors in their work that affect the launch. Checking this is simple - turn off all unnecessary and start the computer.

Doing a forced reboot

If the computer gives at least some signs of life, you can try to force restart it.

To do this, when connecting Magsafe power, you need:

1. press the combination "shiftt" + "control" + "option" / "alt" + "power".

1. if it's an old mac then use "control" + "enter" combination.

Faulty northbridge or southbridge

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 still directly connected to the processor. Damage to any of them requires a mandatory service call.

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

RAM module incorrectly installed

If there was an OP upgrade before the problem, then the module may not have been installed correctly. To check this, just pull it out and insert it again, referring to the instructions. Did not 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 that the macbook does not turn on can be due to many problems. The best thing to do is find out what preceded the breakdown: an unsafe shutdown, a complete discharge, overheating, a physical breakdown, or flooding.

Even if outwardly everything was normal, it is better to ask your family or colleagues if they touched the computer, if there was a blackout, a strange smell. Depending on this, different recovery methods are used.

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 your Mac to a service center as soon as possible. Sometimes repairs may not be required - a simple cleaning may well return the MacBook to working condition.

It is unlikely that anyone will argue with the fact that Apple equipment is of high quality and reliable. It is worth noting that most modern and recently released laptops from other manufacturers are much inferior to the 2008 Macbooks. All available models in the line work without failures, freezes, but this does not guarantee the uninterrupted operation of the device. Sometimes unforeseen situations happen. That is exactly what this article is about. Consider the reasons why the MacBook may not turn on, as well as how to fix them.

How to understand that the "Macbook" does not turn on?

In order to understand that the equipment does not turn on, you do not need to have skill and some special knowledge. It is enough to pay attention to what is drawn on the screen when loading. If an icon appears in the form of a gray folder, on which there is an exclamation mark, then there is a problem with the laptop. You don't need to panic right away. If a system failure has not occurred, then laptop technologies are able to protect all the data that is on the hard drive.

How to reset settings?

If there was a slight hangup, and there is no desire to fiddle with recovery for a long time, then you can use the EFI memory fast rollback function. All data after this will not be deleted and will remain on the hard drive. What needs to be done for this? To get started, turn off the laptop by holding the Command-P-R-Option buttons, you should press the power key. Press on them until the loading screen appears. This will quickly get rid of freezes, the memory will be cleared, and the work of the MacBook will be completely restored. For the future, in order to avoid such troubles, it is better to backup your computer and place it on any cloud storage. Then, in case of an unexpected failure, it will be easy to restore all the data.

If after such a manipulation the laptop still does not start, then you need to check the condition of the hard drive, as well as what kind of fastening the cable has to the motherboard.

Possible reasons

Before choosing ways to solve the problem, it is necessary to determine for what reason the hang occurred. The question of why the MacBook does not turn on will bother every owner who finds himself in such a situation. What caused the shutdown of the software: a system crash, a memory error, a processor error, or any other problems? In addition, a breakdown could also occur as a result of the unstable operation of the operating system. Often such a reaction in a laptop occurs during the update process. Sometimes this happens when you connect an incompatible device to your Macbook. This problem can be easily solved - just turn off all additional equipment.

Fixing the problem: the first way

First of all, you should use the safe way to turn on the laptop - Safe Boot. What is it for? When working with it, "Macbook" loads only that software, which is verified and installed from certified sources. In order to turn on the laptop in this mode, you must press the Shift button and then carry out the usual manipulations. Unfortunately, the download process can be long, but you should not rush or interrupt it, because all data should remain intact.

If the user needs to make a detailed download in order to understand why the failure occurred, then he should start turning on the laptop in the usual way, additionally holding down the Command, Shift and V keys. Then the MacBook will boot into safe mode with the ability to see all the startup details. In other words, Verbose Mode is additionally activated. What does this mean? This download method allows you to find out all the information about the utility and driver files, as well as see all the errors that occurred as a result of their work.

In the event that after such a launch the laptop functions normally, then it can be loaded as standard. But sometimes this method does not help to solve the current problem, then you need to proceed to the second troubleshooting option. If after that the "Macbook Pro" does not turn on, what to do, you can understand further.

Fixing the problem: the second way

Of course, the laptop may freeze and not turn on for many reasons. If we assume that the problem is in the hard drive, then you can use the Disk Utility program to check its status.

First of all, you need to turn off the laptop. If the display shows a gray / blue / other color screen and this does not work, then you will have to turn off the power forcibly. To do this, just hold down the start button for 7 seconds.

Now you can open recovery mode. It is from it that you need to launch the "Disk Utility". How to do it? You need to hold down the MacBook power button, as well as Command and R at the same time. After that, the user will see a screen with utility icons installed in the operating system. You need to find the Disk Utility program and run it. Now you need to find the name of your hard drive on the screen and turn on its verification. After finishing, you need to fix all problems and restart the laptop. However, if the MacBook turns on and off, and the above methods did not help, then proceed to the next step.

Fixing the problem: the third way

If the user has made a backup copy of documents, but cannot get to it due to a failure in the Macbook, then the third method is suitable for him. You need to enter the external disk mode, which is called Target Disk Mode.

How to run it? We need a second MacBook. It is needed in order to connect them with one cable. Now you can turn on your own laptop. If there are any problems, then it is allowed to hold down the power button for a few seconds until the logo appears. Now you need to immediately press the T key. Keep it in this state until an inscription appears on the screen in the form of Thunderbolt. External disk mode is started. At the moment, the laptop is actually just that, and not a familiar computer. If the download is successful, a new hard drive will appear. Thanks to this, you can easily transfer the necessary data to this medium. Now you are allowed to restore the laptop. Even if the information is deleted from the main disk, it will remain on the new additional one.

We fix the problem: the fourth method

If none of the methods described above could help fix the problem and its results, and the MacBook screen does not turn on, then the last option remains - reinstalling the operating system. In order to do everything correctly and not get a failure as a result, you need to enable laptop recovery mode. How to do this is indicated above in the article: you should press the Macbook start button by holding down the R and Command keys.

After that, the operating system will turn on. You need to find the Reinstall menu. A dialog box will open. You must follow all the instructions that are described in it. Now the question of what to do if the MacBook does not turn on should be decided by itself.

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

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

Display Fault Exception

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

How it can be checked:

when you press the power button, you hear the noise of the fan and the operation of disks;

if there are on / sleep indicators, they are lit with the corresponding light;
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 the service center.

hold the buttons throughout the reboot and until the mac again emits a boot melody;
release the buttons.

If an error occurs while powering on (not safe shutdown, emergency shutdown, short circuit), Power Manager, which does not allow you to turn on your Mac, can also be restarted.

first take out the battery;

wait a couple of seconds, let go;
insert the battery back;
press the "Power" button again. The computer should start downloading.

Other reasons

Separately, it must be said about the boot error after the update - while the macbook turns on, but only to a gray screen or a boot screen that does not end.

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 to the old version of the OS, the macbook may not turn on or turn on, but not boot.

RAM module incorrectly installed

The only exception is mechanical damage and liquid ingress.

None of us will doubt the reliability of the Macbook from Apple, because even the 2008 models still compete well with some modern laptops. Therefore, we can say with confidence that the Apple Macbook works without freezes and practically does not break, however, this does not mean that in some cases the laptop will always work like clockwork. Answers why the MacBook does not turn on, and I would like to reflect the ways of their solutions in this article for our readers.

Firstly, a signal that the Macbook is not loading may be the appearance on the computer screen of an icon in the form of a gray folder with a question mark. But for now, there should be no reason to panic, as the reliability of technology allows you to save your data before the computer is turned off. Assuming that a system failure has not occurred, then, no matter what, during internal memory device must have saved all the information.

How to perform a factory reset on Macbook Pro and Macbook Air?

If your MacBook has experienced a slight freeze and you want to quickly restore all data without loss, then you need to perform an EFI memory reset. To do this, turn off the computer, and then, while holding down the Command P R Option buttons, launch the power key, while continuing to hold all the keys until the next system greeting appears on the computer screen. This maneuver will help you avoid system freezes and save data stored on your computer, as well as completely restore work on your Macbook. In the future, it is better to back up your computer data in the cloud storage in case of an unexpected failure.

If, after the operation, your MacBook Air does not boot up on its own again, check the condition of the hard drive, as well as the moment the HDD is connected to the motherboard.

Rescuing data when your MacBook freezes is one of the main tasks, so you need to know the procedure by which your computer will be restored again along with all the data. But first you need to find out why such a freeze happened? Firstly, there could be a problem with the computer, namely: a memory failure, an error in the processor, a controller failure, and other reasons. Secondly, a breakdown can also occur with the operating system, for example, when it is updated to EI Capitan. Thirdly, the reason for the freeze may be the emergence of new connections that are not always compatible with the computer. In the latter case, you just need to disconnect all additional device connections from the USB ports.

To correctly determine the cause of the failure, you need to check the battery and make sure that it is not discharged or has not stopped working, because if the battery runs out during the update of the OS program on the Macbook, then the entire system will most likely freeze. So, it is worth considering several ways to fix the freezing problem on the computer.

Method 1: Safe Boot - Safe Boot Mode

First of all, use the security mode, in which the MacBook will only download verified content when it starts. To do this, deactivate the MacBook to then turn it on while holding down the SHIFT button. Such a launch of the MacBook takes a lot of time, however, you should not rush, because it is more important to download with the least loss.

If you have to carry out a more detailed download with a full clarification of the cause of the failure, then you need to boot your Macbook by holding several buttons: Command + Shift + V. This will give you the opportunity to start Safe Mode on your Macbook and see the details of running Verbose Mode, including the causes of problems.

What does verbose mode mean? Downloading Verbose Mode is a way to boot the operating system, in which specific information about the downloaded files of drivers, programs appears on the display and all the processes occurring in the system during the Macbook boot process are displayed in detail.

If after the above boot your computer can fully recover, then perform a standard reboot of the operating system. If this method did not help you solve the problem of Macbook freezing, then we recommend that you refer to the next method to solve the problem in the future.

Method 2: Download via Disk Utility

It is clear that the MacBook may not turn on and freeze for various reasons. Assuming that this is not a hardware problem, but the hard drive is to blame, then it will not be difficult to check the cause if you run Disk Utility or Disk Utility on your MAC.

First you need to turn off your computer. If your Macbook displays a blue, gray or other color screen with a spinning boot button, then, unfortunately, you will have to turn off your MAC forcibly by holding down the computer start button for 5-8 seconds.

Next, to activate Disk Utility, you need to open recovery mode on your operating system. You can do this in the following way. Hold down two buttons at the same time Command and R and launch the power key. Upon successful login, you will be presented with a screen named MAC OS X Utilities. Now look for the Disk Utility icon on the open screen to activate it. Next, click on the name of your Mac's hard drive, which is on the screen to the left of Disk Utility. Next, start the check by activating the Verify Disk line and wait for it to finish. Finally, activate the verification process by clicking on the Repair Disk line. The next step is to restart your computer.

Method 3. Starting an external drive

Sometimes it's better to play it safe so that you end up in a situation where there is not a single backup copy of your data, and your computer freezes inappropriately. Even if you repeatedly saved backups data, but how now to get to them? This problem was easily solved by your Apple Macbook, as you can use the special external disk mode - Target Disk Mode.

The sequence of actions to start an external disk consists of the following order. To get started, you will need an additional MAC computer for a short period of time. When the second computer is found, connect them using a certified Thunderbolt cable. The next step is to turn off your MacBook, and if necessary, hold down the Power button for a few seconds until the laptop can boot. After your computer starts to boot, immediately press the "T" key and keep it pressed until the Thunderbolt entry appears as an icon on your frozen color screen.

This starts the external drive mode. In fact, the laptop plays the role of an external drive, and not your usual computer. If everything was successful, then soon an external device will be displayed in the Finder - a new hard drive. Using this unusual convenience, you can copy and save all your necessary data before the computer is restored.

After everything is saved to an external hard drive, you will have to move it to the Finder, as you would with a real drive. Then unplug the Thunderbolt cable and start the laptop while holding down the Power button again.

Method 4: Restarting the operating system

When none of the methods gave positive results, and your MAC is still “hanging”, the last method remains - reinstalling OS X. To do everything according to the rules, you need to turn on the laptop in recovery mode and exactly repeat all the steps indicated in the option 2. In particular, we launch the Macbook with the R + Command buttons pressed.

After the operating system starts, find the Reinstall OS X line and, following the instructions that appear on the display, follow all the steps to restart the operating system.

If, after all the work done, your MAC does not start again, then, alas, the problem may be in the hardware and you need to contact the service center, as some parts are out of order, or the cable is broken. However, such a failure could also occur due to the replacement of the old and the connection of new equipment that is not compatible with your OS X. For example, if you put someone else's memory module on your MAC. Therefore, carry out repairs of your devices only in certified service centers and do not be fooled by cheap prices.
