The most common complaint when contacting service center with a MacBook is its "not turning 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 it breaks charger, 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. Frequent breakdowns This key is when 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 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.
No 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 may fail, but also 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:
1 Turn off the power supply. Disconnect the battery. The power supply to the multicontroller will stop and the next time it is turned on, the settings will be automatically reset. 2 Use a keyboard shortcut. All Apple laptops have a combination for this. When pressed, a signal is sent to the multicontroller and the settings are reset. For all the company’s laptops, it works like this: turn on the charger, press the “Shift”, “Control” and “Alt” keys simultaneously. And click the “enable” button. If the charge indicator was orange, then after these steps it will turn green. It is better to do this procedure with the gadget turned off.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.
In one of the previous articles, I wrote about what steps should be taken. I think it would be fair if a similar article appeared about the MacBook.
After all, what could be worse than the situation, when your MacBook won't boot, and you clearly realize that all your information remains on it, the accumulation of which was spent hundreds of working hours.
In this article, I will outline an emergency action plan when your MAC flatly refuses to start. It is not at all necessary to perform absolutely all of the above steps. But we still need to act.
If your MacBook won't boot or freezes on boot, it could be due to:
- problem with hardware (HDD, memory, controller, processor, etc.);
- problem with OS X (for example, upgrading to El Capitan)
- newly installed hardware (disconnect all USB devices)
As with the iPhone that won't turn on, the first thing to do is make sure that MacBook battery it simply did not discharge, and the charging did not fail.
If something is still displayed on the screen or even the boot process begins (which ends up stuck on a spinning disk or even breaks down), you should try following the steps described below in the order they appear.
- If your MacBook is completely frozen and requires a reboot -
- Need to create bootable USB flash drive with OS X?-
- MAC stuck on white screen after updating OS X -
- Read more about different boot modes -
- You don’t know what the screen that appears when you boot your MAC means -
STEP 1: Boot into Safe Mode
First you should try booting your MacBook into safe mode, which limits the checks and downloadable functionality performed by the Mac at startup. I don’t guarantee that after starting in this mode, your MAC will suddenly start working as before, but it’s still worth a try.
Turn off your MacBook and then turn it on while holding down the shift button. Booting into Safe Mode may take a long time (if your computer boots at all), so be patient.
If you want to know what exactly happens when you boot into Safe Mode, you can boot your MacBook by holding down the shift + Command + V buttons, which in turn will launch Safe Mode + verbose mode on your MAC.
Verbose mode- this is an optional operating system boot mode (including OS X, Windows, Linux), in which detailed information about loaded drivers is displayed on the screen, software and processes occurring when the computer boots.
Be patient and careful while booting your MacBook. If your computer does boot into Safe Mode, try simply restarting it from the Apple top menu.
If the MacBook now boots into the usual way, we will assume that the situation has been corrected and now everything is fine. If the MacBook does not boot, proceed to the next step.
STEP 2: Download Disk Utility
There can be a lot of reasons why a MacBook freezes when loading. But let us check now and then discard or try to fix the reason related to your MAC hard drive problems. The easiest way hard checks disk is starting Disk Utility(Disk Utility).
The first step is to turn off your MAC. If MacBook stuck on gray (white, blue, pink...) screen with a spinning disk, you need to force it (the computer) to turn off. To do this, press and hold the power button for 5-8 seconds.
To launch Disk Utility, you need to get into OS X recovery mode. To do this, hold down Command + R when you turn on the computer.
If everything went well, you will be taken to a screen with a title MAC OS X Utilities(see picture below). On this screen you need to click on “ Disk Utility» (Disk Utility).
Then click on the name of the built-in hard drive on the left side of Disk Utility and start the verification process by clicking on Verify Disk on the lower right side of the screen. Wait for the verification to complete.
If any problems are found, you will be prompted to correct them. Confirm your intentions by clicking on Repair Disk. After that, try restarting your MacBook again.
STEP 3: Target Disk Mode
As the saying goes, “it’s better to have a bird in your hands than a pie in the sky.” How are you doing with backup copies data? Well, the data that was stored on your MacBook... And now it won’t start... Sadness!
If data loss on your MacBook doesn’t particularly worry you, skip straight to the next step. But if you are now in a cold sweat trying to remember whether you copied anything valuable to other disks or flash drives, then here is another gift from Apple for you - EXTERNAL DRIVE MODE.
Target Disc Mode is a special boot mode unique to MAC computers that allows you to access your computer's hard drive without booting into OS X.
Using this mode, you can save data when your MacBook does not boot for any reason.
To start external disk mode and access contents of hard MacBook disk do this:
- We find another MAC computer. If you don't have one personally, ask your friends
- Connect both Macs using a Thunderbolt cable
- Turn off your MAC. If necessary, hold down the POWER button for more than 5 seconds
- Hold down the T button immediately after turning on the MacBook and hold it until the blue screen Thunderbolt icons.
You just launched Mode External Disk . This mode, roughly speaking, turns your MAC into external hard disk. If everything went smoothly, your friend's MAC will show an additional external hard drive in Finder. Now copy and save everything you need.
When you're done with the drive, you'll need to eject it into the Finder like any other device. After that, disconnect the Thunderbolt cable and turn off your MAC computer (by holding down the power button for more than 5 seconds).
STEP 4: Reinstall OS X
If none of the previous steps brought “relief,” all that remains is to reinstall the OS X operating system. To do this, you need to boot the computer again in recovery mode, well, remember as in step 2. To do this, turn on the computer while holding Command + R.
Wait for OS X Utilities to load and select from the list Reinstall OS X. Follow the onscreen instructions until complete reinstallation operating system.
If your MAC has not mastered the installation of OS X or has been running on a fresh operating system for a short time, most likely there are some more serious problems with your MAC.
Such problems may occur due to recently installed new hardware (memory, hard drive, etc.). Check your new hardware for compatibility with your computer.
If you haven't installed anything on your MAC, you need to check the existing modules ( hard controller disk, memory modules, etc.). But it is better to entrust such checks to service center specialists.
Mac computers with operating system macOS system on board are the standard of reliability and performance, but even despite this, no one is immune from force majeure circumstances, due to which the operating system may not boot (an apple on the screen) or freeze upon startup. In this article we will talk about typical faults and ways to eliminate them.
Mac not booting or freezing during macOS startup can be due to three main reasons:
- a problem with the software or its update;
- a problem related to a technical component (SSD, HDD, RAM, processor, mother memory, controller, etc.);
- new equipment (needs to be disabled). The cause could even be a regular USB flash drive or USB key.
If the process of launching and loading macOS has begun, but freezes at certain stages, for example, on Apple, then you need to go through all the points below in order in the given algorithm of actions.
1. If MacBook, iMac does not start due to (after) installing an update
Any Mac user Updates the operating system on your computer from time to time. First of all, it's free, and besides, successive releases of macOS provide new features, speed up the device, and better unlock its potential. But sometimes users, after trying to update their operating system, encounter the same problem - Macbook screen(iMac or other Apple computers) the classic “apple” is lit, and operating system doesn't start loading. This is a known problem, and fortunately it is not difficult to fix.
2. Immediately after turning on or rebooting, hold down the key combination on the keyboard Command (⌘) + R.
3. Select the desired language from the menu that appears.
4. Login Disk Utility.
5. A disk will appear on the left side of the active window. It is usually called Macintosh HD. If we fix the problem, the disk will not be mounted. Its name will be displayed in light gray.
6. To mount a disk, there is a button in the top panel of Disk Utility " Connect" Click it and enter your password.
7. The disk name will be shown in the lower right corner, remember it. By default it is - disk2s1.
8. Close Disk Utility and in the top menu bar open the tab " Utilities" Select an application from the list of utilities Terminal.
9. In the Terminal window, enter the following command:
ls -aOl “/Volumes/Macintosh HD/Recovered Items”
Instead of Macintosh HD, you must indicate the name of your disk, if it is different.
10. The line “ No such file or directory».
11. Now you need to enter the second command:
diskutil apfs updatePreboot disk2s1
and press Return (Enter).
parameter disk2s1– this is the default disk name. In your case it may be different.
12. All that remains is to wait for the command to complete. After that, restart your Mac and it should boot normally.
2. Disconnect all devices connected to your Mac and try restarting your computer
How to force restart any of Mac computers we told.
3. Boot macOS in Safe Boot or Verbose mode
Safe Boot or simply “Safe Mode” allows you to run macOS with limited checks and functionality. That is, only the minimum that allows the system to function is launched. We perform all actions from a switched off Mac. To turn it off, just hold down the power button for 2-3 seconds.
MacOS in mode Safe Boot starts a little slower (if it starts at all), so don't rush to the next step until you're sure this doesn't work. To start your Mac in Safe Boot mode, simply turn on the computer while holding down the key ⇧Shift.
There is also an analogue of the Safe Boot mode - Verbose mode. The difference is that the latter allows you to display all the detailed information about the loaded processes, software and drivers. To start your Mac in Verbose mode, start your Mac while holding down the keys Shift + Command + V (⇧ + ⌘ + V).
If the Mac starts in Safe modes Boot or Verbose mode, then you need to click on menu and reboot the machine in normal mode. A successful download means we are lucky.
If the Mac does not boot, then smoothly move on to the next step.
4. We resort to the help of Disk Utility
Our instructions are designed to first weed out the most common and easy-to-fix causes of Mac failure. At this stage, you need to make sure whether the problem is caused by inoperability hard drive or SSD, and will help us with this standard remedy represented by Disk Utility.
Shut down your Mac from any frozen state. Launch Disk Utility performed by turning on the Mac with the keys held down Command + R (⌘ + R). Here you will be in recovery mode.
In the list that appears " macOS utilities» select the item « Disk Utility" and click the " Continue».
In Disk Utility, select hard drive in the left side menu and start the verification mode by clicking on the " First aid» at the top of the window.
After the check is completed, if any malfunctions are detected, the utility will immediately offer to fix them or will fix them automatically. After this, restart your Mac. If it doesn’t help, then proceed to the next step.
