00:00:02,000 --> 00:00:08,733

Hello everyone, in this lesson, let's take a look at the precautions for disassembling an Apple computer.

2

00:00:08,800 --> 00:00:12,933

Its difference is mainly in removing the rear shell and removing the battery

3

00:00:13,733 --> 00:00:18,266

Apple computers are also mainly different after 2017 machines

4

00:00:20,466 --> 00:00:22,400

First, let's take a look at the back shell

5

00:00:22,500 --> 00:00:24,966

It's mainly different in design.

6

00:00:27,666 --> 00:00:33,000

If this is the back case of an Apple computer, then here is the screen hinge

7

00:00:33,800 --> 00:00:38,066

Apple Computer has a drawer-like design on the screen hinge

8

00:00:38,333 --> 00:00:42,300

That is to say, its D shell cannot be lifted directly.

9

00:00:42,600 --> 00:00:48,666

Its screen shaft is stuck here, and it can only be removed by pulling out like a drawer

10

00:00:49,133 --> 00:00:54,300

Apple computers will have 3-4 snaps in the middle

11

00:00:56,366 --> 00:00:59,666

It is mainly because of the drawer design and these buckles

12

00:00:59,700 --> 00:01:02,666

that the back cover of the Apple computer is not easy to remove.

13

00:01:03,900 --> 00:01:06,266

Let's take a look at the disassembly process of the back cover

14

00:01:06,933 --> 00:01:10,166

First we have to remove all the screws on the rear case

15

00:01:10,733 --> 00:01:16,566

After the screws are removed, the D shell is still motionless.

16

00:01:16,800 --> 00:01:21,066

Next, we use the suction cup to pull the D shell up a gap

17

00:01:21,200 --> 00:01:25,633

Note that it must be pulled up in a direction away from the screen axis,

18

00:01:25,666 --> 00:01:28,500

just like the picture in the upper right corner

19

00:01:28,600 --> 00:01:33,833

After pulling up a gap, insert a plastic disassembly card

20

00:01:34,466 --> 00:01:37,133

Move it to both ends of the D shell

21

00:01:38,166 --> 00:01:41,333

Then slide it hard toward the axis of the screen

22

00:01:41,566 --> 00:01:45,400

At this time, the buckles at both ends of the back cover will be pushed open.

23

00:01:45,766 --> 00:01:50,900

You will hear a loud snapping sound when you push the buckle open.

24

00:01:51,566 --> 00:01:56,900

After the buckles on both sides are pushed open, we pinch this gap to lift it up

25

00:01:57,000 --> 00:02:02,166

At this time, the buckle in the middle of the D shell will be opened.

26

00:02:02,433 --> 00:02:05,800

Next, pull down the D shell to remove the D shell.

27

00:02:06,600 --> 00:02:09,266

Let's try it out in practice

28

00:02:10,966 --> 00:02:13,200

Here we have prepared an Apple computer

29

00:02:13,333 --> 00:02:16,000

Let's remove the screws of the D shell first

30

00:02:18,100 --> 00:02:22,500

Apple computers after 2017 generally only have 6 screws for the D case

31

00:02:22,766 --> 00:02:28,133

The two screws near the screen axis are generally longer, and the four screws below are shorter

32

00:02:29,366 --> 00:02:33,166

Generally, the two screws below the touchpad are the shortest

33

00:02:33,766 --> 00:02:36,366

Let's remove all 6 screws

34

00:02:38,900 --> 00:02:41,466

Now we have all the screws removed

35

00:02:41,600 --> 00:02:44,266

Then we find the screen axis

36

00:02:44,733 --> 00:02:49,333

Use a suction cup to suck up a gap at the other end of the screen shaft, and insert a disassembly card

37

00:02:50,166 --> 00:02:53,633

Then slide the disassembly card aside and push it up firmly

38

00:02:56,866 --> 00:03:00,400

Now we hear a snap, which means the buckle has been released

39

00:03:00,500 --> 00:03:02,366

Let's do the other side now

40

00:03:03,533 --> 00:03:05,666

Still push up hard

41

00:03:07,100 --> 00:03:08,533

OK, it's ringing here too

42

00:03:08,866 --> 00:03:10,533

You can see it's open here

43

00:03:10,666 --> 00:03:14,933

After both sides are opened, pinch the D shell and lift it up

44

00:03:15,566 --> 00:03:19,200

After hearing another snap, the buckle in the middle also opened.

45

00:03:19,266 --> 00:03:22,666

At this time, the D shell can easily shake up and down.

46

00:03:23,700 --> 00:03:27,166

Next, we pinch the D shell with our hands and pull it down.

47

00:03:27,866 --> 00:03:30,900

In this way, the D shell is removed.

48

00:03:31,733 --> 00:03:35,300

The here of the D shell and the here of the C shell are interlocking

49

00:03:35,500 --> 00:03:37,466

This is the design of its drawer

50

00:03:37,766 --> 00:03:40,733

Now the D shell is removed by us

51

00:03:42,500 --> 00:03:45,300

After the back cover is removed, let's take a look at the battery

52

00:03:45,500 --> 00:03:49,266

Apple's batteries are not the same as ordinary computer batteries

53

00:03:49,766 --> 00:03:53,266

The battery of the Apple computer is under the protective sheet.

54

00:03:53,666 --> 00:03:57,533

After we remove the protective sheet, we will see a structure like this

55

00:03:58,366 --> 00:03:59,900

There are two cables

56

00:04:01,300 --> 00:04:03,933

Here is the small plate of the battery

57

00:04:04,966 --> 00:04:08,566

The connection between the battery board and the motherboard mainly depends on two cables

58

00:04:08,866 --> 00:04:13,200

One is a relatively wide cable locked by screws, and the other is a relatively thin cable

59

00:04:15,700 --> 00:04:19,833

This thinner cable is mainly used to transmit battery data

60

00:04:19,833 --> 00:04:24,733

This screw-locked cable is used to connect the positive and negative terminals of the battery

61

00:04:25,566 --> 00:04:31,166

When we remove the battery, we must first remove the data cable of the battery.

62

00:04:31,466 --> 00:04:37,100

After the data cable of the battery is removed, remove the positive and negative fixing screws of the battery

63

00:04:37,766 --> 00:04:40,733

After removing the screws, the battery is disconnected

64

00:04:41,466 --> 00:04:43,400

Next let's try

65

00:04:43,700 --> 00:04:45,600

The battery cable is under this protective sheet

66

00:04:45,766 --> 00:04:48,066

Let's take off the protective sheet first

67

00:04:52,200 --> 00:04:57,166

After the protective sheet is removed, you can see the two cables connecting the battery to the motherboard

68

00:04:57,766 --> 00:05:01,300

A screw-locked flex cable, another small flex cable

69

00:05:01,600 --> 00:05:03,300

Let's remove this little cable first

70

00:05:04,533 --> 00:05:10,700

After the small cable is removed, we use a screwdriver to remove the screw and disconnect the large cable

71

00:05:12,333 --> 00:05:17,533

When the large cable is also disconnected, the battery is disconnected from the motherboard

72

00:05:17,933 --> 00:05:21,100

The next disassembly process is similar to that of a normal computer.

73

00:05:21,200 --> 00:05:23,266

Remove the screws and remove the motherboard

74

00:05:24,766 --> 00:05:29,400

Well, the above are the precautions for Apple computer disassembly
