Macbook is dead and won't turn on. What to do if MacBook won't boot. Deep Discharging the Battery

In this article, we will analyze the 6 main reasons why the MacBook may not turn on. We will tell you about possible ways diagnostics at home, and also try to help you fix the problem.

Let's immediately decide that by "does not turn on" in this article, we mean the state of the computer in which it does not react in any way to pressing the power button, whether it is when charging is connected or not.

This article will most likely be useless if your MacBook after pressing the power button:

• makes a turn on sound
• fan noise heard
• the sleep indicator lights up (if equipped)
• when you press the caps lock key, it lights up

The main reasons why the MacBook does not turn on

1. One of the most common reasons for "not turning on" is a power supply failure. Most often, the MagSafe magnetic tip fails. The main cause of failure is the twisting of the wire and, as a result, damage to the internal contacts of the tip. In this case, you must either replace the charging cable with a MagSafe tip, or buy an original charger. To test this hypothesis, connect a known working power supply to the computer. In the absence of such, take your computer with you to work, and along the way, drop by any store that sells original Apple chargers. Ask to connect the charger to the computer and if everything works, you can immediately purchase it.



By the way, have you tried plugging the power supply into a different outlet? ;-)

2. Malfunction peripherals can also cause this failure. Turn off one device at a time, and after turning off each device, try turning on the Mac. If at some point it turns on, then the problem was in the last disconnected device.
3. SMC system management controller failure The main symptoms of this controller failure are the following symptoms:
   • no response when pressing the power button
   • The indicator light on the power supply is not working properly. For example, it does not light up when connected to a computer.
   In this case, it is worth trying to reset the SMC settings. This is done in two ways:
   • connect charger to macbook then press and release at the same time the following buttons Shift+Ctrl+Alt+Power button (On MacBooks since 2016, the Touch ID button is the power button). Pay attention to the indicator light on the power supply, in case of a successful reset, it should go out and light up again first green and then orange. You can read more about resetting SMC on the Apple website at the link.
   • If resetting the SMC did not help, you can try disconnecting the battery for 5-10 seconds.
4. Deep or complete discharge of the battery. In terms of its symptoms, deep discharge is very similar to point 3 of this article. This problem is solved by resetting the SMC controller, or you can also try disconnecting the battery from the motherboard.
5. Failure of the ON button. Perhaps the main and only reason why the power button can break is the external factor of liquid getting on the keyboard. The fact is that since 2008 the power button is built into the keyboard and its contacts go through it directly to the motherboard. In this connection, the liquid that gets on the keyboard can "touch" the conductive tracks of the power button and damage them. In order to eliminate this outcome, you must disconnect the keyboard from the motherboard and connect the power supply. If the MacBook turns on, then it's definitely the keyboard. However, the diagnostic method described above is only suitable for models manufactured since 2011 inclusive.
6. If you have tried everything that was written in this article and nothing helped you, then most likely it's rubbish - the motherboard has failed. Unfortunately, at home without skills and special equipment, you cannot do anything. In any case, you will have to contact the service center.

It should be understood that if your MacBook does not turn on due to physical impact, for example, a strong blow or liquid ingress (popularly - flooding), then you can’t do without contacting the service center either.

Question: Good afternoon! You have useful and interesting articles and I would like to contact you with diagnostics, but I do not live in Moscow. I want to ask this question. I have a macbook pro 13 mid 12 last year I changed the hard drive to seagate though it is more nimble (7200) than my native hitachi. He worked for me for 14 months and stopped loading. I thought he was dead and bought another Hitachi. I put the old native hdd in place with it, the poppy worked fine, downloaded Yosemite and connected the new disk via USB and installed the system. But stuck inside the poppy, he worked with glitches. And through yusb worked fine. I gave this disc to the store and bought another Seagate. The same problems, only inside the poppy it does not start at all, only yusb. Is it a problem with the loop? It's just strange that the old hdd works with this cable, while others do not, although the disk with which this problem happened was also bought in a store and worked fine

What to do if the macbook refuses to turn on?

Each manufacturer tries to make their device as modern, convenient and compact as possible. But unfortunately, it is very difficult to avoid breakages and defects. Apple technology is no exception. Apple company from Cupertino has created an ultra-thin and powerful laptop. And by tradition, Apple decided to name its New Product original name. MacBook is a reliable computer, but unfortunately it can fail. A broken laptop can fail both technically and software. We will consider various options for breakdowns and consider various ways out of a difficult situation.

Instructions for restoring the work of a macbook

So let's take a look at the following diagram:

1. Let's say that your laptop does not turn on. Turn off everything first additional devices connected to a MacBook.
2. Of course, the MacBook must be turned off. First, disconnect the compact network cord from the computer and from the network. You have to wait about a minute. Now we connect the ordinary device first to the network, and then to the MacBook itself. The indicator after connection should light up green or yellow.
3. If with network adapter and with the cable itself everything is in order, then the indicator will light up. If there are any problems with the power supply network, then the adapter, accordingly, will not light up. In this case, the laptop does not turn on due to a defective part. You need to contact the Apple Service Center.
4. So, if there are no problems with the network, and the equipment starts up, 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, connect the power adapter to a working power source. Now we press a bunch of keys "Option + Control + Shift" and at the same time with this bunch we press the button to turn on the MacBook. We count 5 seconds, and then press the power key again. After that, the macbook should turn on while the boot process is in progress, check the sleep indicator - if it blinks, then the boot cycle is completed.

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

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 technique 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. In the future, to avoid such troubles, it is better to do backup computer and put 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 status hard drive, as well as what attachment 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" downloads only software that 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 you 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 method download allows you to find out all the information about the utility and driver files, as well as see all the errors that have 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.
