Do-it-yourself MacBook repair: troubleshooting instructions.

Twitter

Determining the cause of a malfunction is the very first thing to start with a MacBook repair. And the point here is not that "it should be so", but that replacing components in Apple laptops is a very costly process, so you should be sure that it is really necessary.

Service cost:

Malfunctions that a MacBook user may encounter can be divided into two groups:

Software

They are associated with incorrect installation and operation of the Mac OS X operating system or software. In this case, problems arise directly during or after working with any application, or may appear at regular intervals.

They are caused by a malfunction of laptop modules such as the MacBook motherboard, hard drive, matrix, etc., in which case it will require repair or replacement of MacBook components.

MacBook Self-Diagnosis Steps: What You Can Do Before Contacting a Service Center

If you ruled out a software glitch, the cause of the problem may lie in the connected, but not working correctly equipment. Turn off the device and try to disconnect all external equipment, leaving only the mouse. If the laptop starts working normally, then further diagnostics of the MacBook will consist in alternately connecting the equipment and turning on the laptop. This will help you determine what exactly caused the problem.
If this does not help, and the laptop continues to work in an incorrect mode, it is worth checking the hard drive, and also to exclude problems with access rights. There are two programs for diagnosing a disk in MacBooks - Disk Utility and the fsck command (the latter is used for MacBooks with OS X 10.4 or earlier). Verification must be carried out in a safe manner.
You can use the Functional Hardware Test to diagnose MacBooks running OS X 10.7 or later, and Apple Diagnostics for devices shipped in July 2013 or later. In this case, it is very important to disconnect all external equipment, as well as connect the laptop to the network.
To enter the MacBook diagnostic mode, after turning on the laptop, hold down the D button. A gray screen will appear, and it will be possible to launch the utility to check the hardware (you can choose a full check or a partial check). If the diagnosis is successful and the cause of the failure is identified, a message will be displayed with a record of the corresponding error.

Comprehensive MacBook diagnostics - only at a service center

The ability to independently diagnose a MacBook is, of course, great, but a complete picture of the laptop's performance can be obtained only by contacting a service center. For example, if the computer does not turn on or preventive maintenance was not carried out, the cooling system is out of order, the battery or charger is damaged, it will be possible to determine the cause of the malfunction only after disassembling the laptop and ringing the circuit. Such diagnostics will be required for the MacBook even if it has been dropped or has been flooded with liquid.

Disassembling an Apple laptop is not easy, even for a specialist, so you should not try to open the case yourself and get the accessories. Contact the service center - and the MacBook diagnostics will be carried out thoroughly, and the wizard will be able to establish the exact cause of the equipment malfunction.

Check the exact price for repairs with the manager by phone.

Question about the keyboard MacBook Pro 2011 ~ Pavel ~ 06/15/2016

Good day!
I have a MacBook Pro 2011 Unibody. I clean it periodically and change the thermal paste. During the last thermal paste replacement (parsing, removing the motherboard mat), I inadvertently damaged (tore off) the touchpad cable. Having decided that I would use the mouse before replacing it, I collected it, which, in general, was not the first time I was doing it, and found that the keyboard did not work either. After that, I disassembled and checked the keyboard cable a couple more times, but there was no result. The keyboard is silent

Hello, I have MBP 13 "late 2011, when a second monitor is connected via a Mini DP - VGA adapter, the image on it appears for a second and disappears.

Problems with MacBook Pro ~ Nikita ~ 12/21/2015

Good afternoon. Unpleasant and unexpected things happen to my poppy. Mac is a little over a year old, never let me down and worked perfectly. For the last three days, the following has happened to him:

My Mac has more than 20GB of free space, but in recent days, as soon as I turn on my poppy and the memory melts in a matter of minutes, it displays a message that the boot disk is full, demands to close all programs (and closes them itself) and the memory shows 0kb. That is, the work of the poppy can take no more than 10 minutes. After that I have to recharge it (with which unexpectedly, too, there were problems and it does not react every time). After rebooting, there are again about 27 GB free, and each time to check it, I delete a lot of things from the poppy to clean up.

In this situation, before going to bed, I turned off the poppy, in the morning I found that it did not turn off and at the same time the battery charge was at zero. The monitor, as far as I remember, went out.

I'm used to the fact that after walking away for about 15 minutes, the poppy goes to sleep. Gathering in the morning on business and returning in the evening, I found that the monitor at the poppy was turned on as it had been a few hours ago. He did not go into sleep mode.

What could all this be connected with ?? All this has been happening since December 18 (4th day), before that it worked properly.

Macsave Center's answer: Good day, you need to diagnose, probably a malfunction in the power circuits

When you insert the charger into the poppy, the light on the charger does not light up, but if you insert it into another working poppy and then into my non-working one, it glows orange! I would have given it to your center for diagnostics and treatment long ago, but I am very far away, and there is no apple service in our city. What would you advise?

Macsave Center's answer: Good afternoon, you clearly have a problem in the power supply circuits of the motherboard pin

MacBook Pro 15 (Late 2008) ~ Dmitry ~ 05/16/2015

Hello, the insulation near the L-connector peeled off, I decided to re-solder it - I crushed the LED and broke off a piece of the board when I tried to remove it. The Mac worked from the mains, but stopped charging the battery. I ordered a new cord with an L-connector, while the cord was waiting, the battery was discharged to 1-2%. I managed to turn off the Mac as usual.
I re-soldered a new cord, plugged it in, the Mac does not start. I installed the battery - it started. But! The indicator on the L-connector is NOT LIGHTING! (neither green nor orange) sinned on a Chinese counterfeit, I thought there was no LED at all. The Mac is running on mains, sees the battery BUT does not charge. With the Mac running, I pulled out the battery, worked from the mains for a while, then hooked and pulled out the plug. The Mac passed out and then stopped starting with or without a battery. Read that resetting the SMC can fix the startup problem. But when resetting, the Mac does not react in any way, the indicators are silent, it still does not start.
Since the battery was inflated, and then there was a full discharge - I ordered a new A1281. PRAM / NVRAM reset after forced start * (no battery). Also, not any changes.
* (Disconnect MagSafe, hold Power for 5 seconds. Without releasing connect MagSafe, hold Power for another 5 seconds, release, wait a couple of seconds, launch Mac). The Mac was forced to start, but with all the problems that arise when you need to reset the SMC (Indicators-Fans-Lighting-Power).
A new battery arrived: the Mac started from it forcibly *, but writes: There is no battery Power source: battery. (B-rr-rrrr)
I took a Mac (without battery), charging and went to a neighboring city, found an Apple point. The seller turned out to have Air with 60w, plugged it Magsafe into mine - the indicator turned green, but after 10 seconds it dimmed and soon went out altogether (what the hell - I think that's it! I burned the guy with MagSafe), plugged it back into my Air - it works. My Mac did not start with lack of power. They took my 85w with a soldered new cord - L-con. Inserted into Air - lit up green !!! Hooray! The cord is still working. I put it in my back and no reaction.
Results: I replaced the cord with the L-connector, bought a new battery.
Mac starts only forcibly, SMC is not reset. The LED on the plug does not light up. On the battery charge indicator, the 6th indicator is constantly shining, which is from the network - which is from the battery. I checked that power is supplied to the MagSafe board and from it to the Motherboard in full. All contacts are called. Maybe there is some kind of diagnostics that can still be done at home besides (D-at startup), everything is clean there.

Macsave Center's answer: Good afternoon, everything clearly points to the motherboard power circuits. Only diagnostics in the SC will help

Poppy slows down ~ Alexander ~ 30-04-2015

What about him? ~ Evgeny Voevodin ~ 07-04-2014

Hello!
There is a 13-inch macbook air, mid-2012. OSX 10/9/2 The problem is as follows: it works fine, does not heat up, does not buggy, incl. under loads, only if loaded. And it loads within a couple of hours - easily, maybe longer. First, a white screen for 20-40 minutes, then the user's choice, the same amount, slows down unrealistically, the asterisks when entering the password are displayed with a delay of at least 5 seconds. But after that, when you wake up from sleep mode - no problem.
The problem is that I am in Sevastopol, local masters cannot advise anything except how to replace the motherboard, and they cannot do it either ... I sit thinking to buy a new one, or are these some typical problems for some specific problem with a certain the final cost. Thanks!

Macsave Center's answer: Good afternoon, often problems are in SSD hard drives and cables on the MacBook motherboard, the south bridge could also fail. A complete diagnosis is required.

Installing the macbook a1181 operating system ~ Stanislav ~ 17-03-2014

Good afternoon, I have the following problem, I will try to describe it step by step.
I have a macbook 1181, I got it by inheritance, the previous owner did not spare him much.
At some point, the operating system stopped loading. After starting the laptop, an apple icon appeared and a rotating circle under it, then nothing happened, I tried to leave it overnight, in the morning the same thing.
According to the previous owner, this has already happened to him, the operating system also crashed, it was solved by reinstalling it. Latest OS 10.7.4

When trying to reinstall the OS on the same 10.7.4, the system hangs in the process of preparing for installation. I waited several hours, no result.
I replaced the hard drive in my laptop, formatted it in accordance with the instructions, tried to install OS 10.6.3, the same situation, it will write down on the last minutes of boot. At some point, it loaded up, after which the screen went out. I forcibly rebooted it, and left it to boot from the hard drive, it spun (30 minutes) and played a melody, but the screen remained gray.
The last time I tried to reinstall the OS, the process froze for about 30 minutes to complete (the screen worked, but did not respond to the touchpad).
I also tried to change the bootable USB flash drive, the result is the same.

Please tell me what could be the matter?

Macsave Center's answer: Good afternoon, often this is how problems with the hard drive appear, it is time to change the hard drive in your laptop, because in the Mac A1181 during this time more than one hard drive has changed, as an option the north bridge may be, but this is rare.

MacBook small 11 screen does not work ~ Yana ~ 09-10-2013

Hello, I have an Apple Air 11 screen below it says MD508. Help me make my baby, I turn it on with a button, but he does not give life signals, everything is silent and the screen does not light up, so I understand it is necessary to do diagnostics?

Macsave Center's answer: Good afternoon, maybe there is a problem in the MacBook power connector or a power problem on the motherboard, we will make diagnostics during the day and say what is the reason for your Ira.

Fair, not overpriced or understated. There should be prices on the Service website. Necessarily! without "asterisks", it is clear and detailed, where it is technically possible - the most accurate, final.

With the availability of spare parts, up to 85% of complex repairs can be completed in 1-2 days. Modular repairs take much less time. The website lists the approximate duration of any repairs.

Warranty and liability

Any repairs must be guaranteed. Everything is described on the website and in the documents. The guarantee is self-confidence and respect for you. A 3-6 month warranty is good and sufficient. It is needed to check quality and hidden defects that cannot be detected immediately. You see honest and realistic terms (not 3 years), you can be sure that they will help you.

Half of the success in Apple repair is the quality and reliability of spare parts, so a good service works with suppliers directly, there are always several reliable channels and a warehouse with proven spare parts of current models so that you do not have to waste extra time.

Free diagnostics

This is very important and has already become a good form for the service center. Diagnostics is the most difficult and important part of the repair, but you shouldn't pay a dime for it, even if you don't repair the device as a result.

Repair in service and delivery

A good service appreciates your time and therefore offers free shipping. And for the same reason, repairs are carried out only in the workshop of the service center: correctly and according to technology, it can only be done at a prepared place.

Convenient schedule

If the Service works for you, and not for itself, then it is always open! absolutely. The schedule should be convenient so that you can be in time before and after work. Good service works both on weekends and on holidays. We are waiting for you and working on your devices every day: 9:00 - 21:00

The reputation of professionals consists of several points

Age and experience of the company

Reliable and experienced service has been known for a long time.
If a company has been on the market for many years, and it has managed to establish itself as an expert, people turn to it, write about it, and recommend it. We know what we are talking about, since 98% of incoming devices in the SC are being restored.
We are trusted and transferred by other service centers for difficult cases.

How many masters by directions

If you are always waiting for several engineers for each type of equipment, you can be sure:
1. there will be no queue (or it will be minimal) - your device will be taken over immediately.
2. You are handing over your Macbook to a Mac repair expert. He knows all the secrets of these devices

Technical literacy

If you ask a question, a specialist must answer it as accurately as possible.
So that you have an idea of what exactly you need.
They will try to solve the problem. In most cases, the description tells you what happened and how to fix the problem.

As you know, Apple pays a lot of attention to the organization of maintenance and repair of its devices ... while they are under warranty. If the warranty period for your MacBook has expired, then its repair can result in a serious amount. You may be charged a few hundred dollars for some trivial problem.

Therefore, let's deal with those problems that we can fix ourselves. Here I have collected all the important information on how to repair a MacBook with your own hands. It also comes in handy for Mac desktop users.

Before you start: backing up

If your MacBook starts to work with problems and you are going to deal with them, then before proceeding with action, create a backup copy of all important information.

I hope you already know how to use Time Machine. Use this utility to create a copy of your Mac to an external drive or online storage. Ok, let's start troubleshooting MacBook problems and fixing them.

1. Download updates and check for viruses

In the first step, make sure that the latest software versions are installed on your computer. Download the latest updates for your operating system, applications, component firmware ... absolutely everything. Launch the App Store and go to the Updates section. If an update is ready for some software product, install it.

If you installed some programs not through the App Store, then run each of them separately and check if they are ready to update.

After updating the programs, run an anti-virus scan (after updating the anti-virus) to make sure that there are no viruses and other malware that could be the source of problems with your computer. You can also use a program to find and remove adware, such as Adware Mdic. Just don't use MacKeeper for this.

Many users still live in the dark and believe that viruses do not threaten Macs. But the situation has changed a long time ago, and unwanted programs displaying ads can easily get into your system.

After updating and checking for viruses, restart your computer. It is possible that it will work without problems.

2. MacBook diagnostics

If the problem persists on your Mac, you need to find out the source. First, you need to decide on the category of the problem: software or hardware. To test the hardware, you need to run Apple Diagnostics (or Apple Hardware Test, depending on the age of your computer). To do this, we will use the following algorithm:

Shut down your MacBook and disconnect all peripherals from it (except the network adapter, mouse, keyboard, and Ethernet connector).
Hold the D key until the Apple Diagnostics download begins.
Select a language and press the Enter button.
If your Mac was released earlier than 2013, then select “Perform extended testing” and click “Test”.

The procedure for diagnosing the hardware filling of the computer will begin. This can take a long time - be patient. At the end of the diagnosis, a table with information about the found problems with the hardware will appear on the screen. Write it all down somewhere and restart your computer.

The built-in Disk Utility of OS X can detect a number of file system problems, especially those related to permissions.

If these diagnostic tools do not find anything, then you will have to use an alternative method. Explore "Troubleshooting Mac OS X" - in this document, Apple has put together helpful tips to help you find the source of your computer problems. Having found it, you may yourself understand the further strategy for repairing MacBook or you will have to look for relevant information on thematic forums.

If you still don't know how to get full functionality back to your Mac, read on.

3. Problematic programs

Let's start with what is easier. As a rule, problems with software are solved cheaper and faster.

Correcting access rights

Incorrect access rights often create difficult-to-explain problems. Fixing them in many cases allows you to quickly solve seemingly incredibly complex problems. Launch Disk Utility (Applications -> Others) and click the Check Permissions button.

The utility will almost certainly find several objects, the permissions to which it will advise you to fix. After it completes its work, click the "Fix access rights" button. If the list of fixes is long enough, this procedure will take several minutes. You can relax and have a cup of coffee for now.

Resetting PRAM and SMC

The random access memory where system parameters are written (PRAM) and the System Management Controller (SMC) are responsible for many important things in your Mac. To reset PRAM, do the following:

Turn off your computer.
Press the computer power button.
Press the Command, Option, P, and R buttons at the same time until the gray screen appears.
Hold these buttons until you hear the computer boot sound again.
Now release the buttons.

Resetting the SMC depends on the type of computer you are using. On a MacBook with a removable battery:

Turn off your computer.
Unplug the AC adapter.
Remove the battery.
Press and hold the power button for five seconds.
Insert the battery back.
Turn on your computer.

On a MacBook with a non-removable battery:

Turn off your computer.
Connect the AC adapter.
On the built-in keyboard, press the Shift, Control, and Option buttons on the left and the power button at the same time.
Release Shift, Control and Option at the same time.
Turn on your computer.

On a Mac Pro, iMac with an Intel processor, Mac Mini with an Intel processor, or Xserve on Intel:

Turn off your computer.
Unplug the power cord.
Wait fifteen seconds.
Plug in the power cord.
Turn on your computer.

Removing problematic programs

If you still haven't gotten your MacBook to work properly, and you suspect a particular program is causing problems, then try uninstalling it and see if your computer works better after that. If this is the case, try installing this program again. Sometimes this is all there is to do to repair your MacBook. If you still have problems, then try a few more things.

Reinstall OS X

We are moving on to decisive action. Sometimes the operating system has serious problems that can only be fixed by reinstalling. That's why you backed up your Mac at the beginning of this article.

If you have OS X Yosemite installed (you've already upgraded your Mac), then proceed as follows:

Restart your MacBook.
When you see a gray screen, press and hold Command + R.
Options should appear, among which select "Install OS X" (Install OS X).
Follow the instructions on the screen.
The operating system will reinstall. See if the problem is gone.

4. Hardware problems

If your MacBook has a hardware problem and you want to fix it yourself, then you will have to use online resources filled with useful information. The Apple Diagnostics or Apple Hardware Test information should be a starting point (assuming the utility is running and the computer display is running, of course). Sometimes, diagnosing hardware problems can be very difficult and requires professional skills and tools.

Collecting information

Before you start repairing your MacBook hardware, you should be well prepared and collect the necessary information. There are quite a few resources on the Internet about Mac repair. I recommend starting with iFixIt, Instructables, and YouTube. Before disassembling your MacBook case, read or view the instructions carefully and make sure you have everything you need.

MacBook Repair Tools

Unfortunately, to repair Apple laptops, you will need tools that are not included in the traditional home kit. In the iFixIt online store and in local hardware markets, you can find almost everything you need: ingenious screwdrivers, soldering tools and special kits.

You can also search Amazon and eBay for the repair fixtures you need. In the latter case, the prices may pleasantly surprise you (only delivery is likely to cost a pretty penny). Used tools are unlikely to lose their functionality after repairing one or two computers.

Where to get spare parts

On eBay, you can find not only tools, but also replacement parts for MacBooks, from motherboards to displays. You can also buy a faulty Mac at a low cost, in which we will find many working parts to repair. iFixIt also sells Mac parts.

Before buying, check a hundred times that this is exactly the part you need. Protect yourself from incompatibility issues. If you are not sure about the exact name of this part, on your MacBook go to the Apple Menu (in the upper left corner of the screen) -> About this Mac -> System Report and find a description of the required component there (of course, if the computer turns on) ...

Get down to business!

If you know what to do, have prepared the tools and the necessary parts, then it's time to start repairing your MacBook. Reread the required instructions. Protect yourself from possible electric shock and proceed.

Be patient. Repairing a modern computer is a very delicate task, there are many small and fragile parts, and some of them can be irreparably damaged by static electricity. Be extremely careful when working with the battery and microcircuits.

Or maybe a service center?

Fixing a MacBook takes time, patience, and sometimes a lot of money - but it comes with a return to computer performance and increased self-esteem.

I recommend taking on major repairs only if you like digging into the stuffing of electronic devices. After solving serious hardware problems with Macs a few times, you will be transferred to the group of favorites.

But for most of us, you should outsource your Mac major repairs to a trained professional. You can try to take the relevant courses yourself. But they are unlikely to seem simple to you. Therefore, most users entrust the repair of their MacBook to a professional. Yes, you will give more money, but you will receive qualified help.

In what situation are you ready to fix your computer yourself? And when would you prefer to entrust its repair to a qualified person? Share your opinion in the comments.

The easiest way to avoid the help of service centers when looking for hardware problems (not all of them can boast a good reputation) is to use the built-in Mac diagnostics. In this article, we will tell you how to run and use " " and " Apple Diagnostics».

In contact with

With the help of standard diagnostic tools, you can effectively detect hardware malfunctions (problems with a hard drive, solid state drive, RAM, GPU, motherboard and other nooks and crannies of hardware). How can this be done?

On which Macs which utility

Regardless of (MacBook, iMac, Mac mini or Mac Pro) and year of release, the operating system includes a utility for self-diagnosis of the hardware. In computers that were produced before June 2013, it is called " Apple Hardware Functional Test"(Apple Hardware Test - AHT), and after -" Apple Diagnostics».

Before starting any of the utilities, be sure to disconnect all peripheral devices (including optical drives, if you still have such antiquity) except for the keyboard, mouse, display and Ethernet adapter. Some versions of OS X Lion and later may need Ethernet or Wi-Fi to run the internet version of AHT. It is no different from its offline counterpart.

To use AHT, be sure to connect your MacBook to a power source.

List of keyboard shortcuts

If you don't have a mouse, then the following shortcuts will come in handy:

Option (⌥) + D: run diagnostics with the Internet;
Command (⌘) + G: start the operation;
Command (⌘) + L: display a list of languages;
Command (⌘) + R: restart the test;
S: shutdown;

How to Run Diagnostics on Mac (Apple Hardware Function Test or Apple Diagnostics)

Note: " Apple Hardware Functional Test" and " Apple Diagnostics»Work in the same way. The only caveat is for launching " Apple Diagnostics"An active Internet connection is required, and the interface will be much nicer.

1 ... Turn on or restart your Mac if it's on.

2 ... While switching on, press and hold the " D»Until the language selection screen appears.

3 ... Select the language (if a mouse is not connected to the computer, then select the language using the arrows, and enter the input with the "Enter" key).

4 ... Mac diagnostics will start.

After the check is complete, the results are displayed.

To exit the ANT utility, press the button " Reboot" or " Switch off"At the bottom of the window.

What do the results indicate?

If, during the test, problems with the hardware are found, then get ready to contemplate the error and some explanatory details.

You can decipher AHT errors on the Apple technical forum, and in general, I recommend that you first of all, when looking for solutions to problems with apple gadgets, go there. True, you need knowledge of English at least with a dictionary.

Apple Diagnostics error codes and their interpretation can be found below:

ADP000- No problems found on the computer;

CNW001, CNW003, CNW004, CNW005, CNW006- There are problems with the Wi-Fi module on the computer;

VFD006- There is probably a problem with the GPU;

VFF001- There is probably a problem with the audio hardware component.

In any case, if it was not possible to avoid repair at the service center, we strongly recommend that you contact only certified specialists who specialize exclusively in Apple technology. It will not be cheap, but buying a new gadget is much more expensive. It's better to forget about the basement workshops "at Uncle Vasya's". Apple device repair requires a very meticulous approach and advanced skills.

Before going to the service center with their Mac, any user can independently check their computer for problems. Perhaps, knowing what the problem is, the user will be able to carry out simple repairs on his own.

Since Apple's instructions are of little use in this case - they are sent exclusively to the service center, I have compiled my own guide to solving problems with Mac.

If the computer was released after June 2013, then the checker is called "Apple Diagnostics"
If the computer was released before June 2013, the test program is called "Apple Hardware Functional Test"

Regardless of the name, the utilities work almost identically.

How do I run Apple Diagnostics?

Step 1. Disconnect all devices except the mouse, keyboard, network cable, and monitor.

Step 2. Turn off your computer.

Step 3. Turn on the computer and press the D button. Hold it until a special screen appears with a choice of language.

Step 4. Choose Russian and the check will start automatically. It does not last very long - 2-3 minutes.

If you do not start the usual diagnostics, then at boot press Option + D and the diagnostics will start using the Internet. For example, I had to do so, because I changed hard disks in MacBook a long time ago and, naturally, I no longer have a recovery partition. This picture can hang for 5 minutes. If it freezes, then restart your computer.

This is how the diagnostics look like on the MacBook Pro 2011. At the beginning, we find and select the line "Select Russian as the main language":

After that we press "Test":

Apple error codes on MacBook

PFR001	There may be a problem with the computer's firmware.
PPF001 PPF003 PPF004	There may be a problem with the fan.	You can theoretically disassemble the laptop, remove the fan and clean it. I do this every six months.
PPM001	There may be a problem with the memory module.	The laptop can be disassembled. Get out the memory modules, if possible, swap the brackets.
PPM002 PPM003 PPM004 PPM005 PPM006 PPM007 PPM008 PPM009 PPM010 PPM011 PPM012 PPM013 PPM014 PPM015	There may be a problem with the built-in memory.
PPP001 PPP002 PPP003	There might be a problem with the power adapter.	Unplug the AC adapter from the wall outlet and from the computer. Reconnect and test.
PPP007	The power adapter has not been tested.	Reconnect the power adapter to a guaranteed working outlet. Run the scan again.
PPR001	There might be a problem with the processor.	Sadness if the error is repeated ... Here it is definitely better to refer to the service.
PPT001	No battery detected.
PPT002 PPT003	The battery will need to be replaced soon. It is serviceable, but its capacity has decreased.	On some Mac models, the battery can be completely replaced by yourself.
PPT004		It is required to re-run the diagnostics via the Internet (described at the beginning of the article). Apple uses the most up-to-date battery diagnostics over the Internet. If the problem is confirmed and the battery does not work for you, then think about replacing it.
PPT005	The battery is installed incorrectly. Shut down and shut down your computer. Your computer needs service.	Disconnect and reconnect the battery.
PPT006	The battery needs service. The battery is defective, although this may not affect performance or capacity. Until the test is completed, you can continue to use the battery without damaging your computer.	I would still replace the battery if the capacity drops to zero, because without it, Mac OS will automatically slow down the computer's performance. Reaches up to noticeable brakes.
PPT007	The battery needs to be replaced. The battery is in good working order, but its capacity has decreased significantly. Until you replace the battery, you can continue to use it without damaging your computer.	The above advice is given!
VDC001 VDC003 VDC004 VDC005 VDC006 VDC007	There may be a problem with the SD card reader.
VDH002 VDH004	There might be a problem with the storage device.	Check hard drives for errors with special utilities.

VFD006	There might be a problem with the GPU.
VFF001	There might be a problem with the audio hardware component.

What else do you need to know?

The test does not always display errors. Here I have some problems with the SD slot, but the test did not reveal any errors. Extended testing may be required.
