Hello everyone, today we are going to talk about the Apple's laptop mainboards

2

00:00:07,666 --> 00:00:12,966

First let me introduce the older A1278, A1398 mainboards

3

00:00:15,633 --> 00:00:19,000

The Apple A1278 mainboard is what we see here

4

00:00:23,033 --> 00:00:26,166

It uses the second and third generation Core processors,

5

00:00:27,066 --> 00:00:29,266

PCH and CPU are separate

6

00:00:32,233 --> 00:00:36,600

Next to this is the BGA chip, and this is the lightning chip,

7

00:00:37,366 --> 00:00:40,633

which is responsible for managing the lightning interface

8

00:00:44,033 --> 00:00:47,266

The mainboard's memory is pluggable for easy upgrading

9

00:00:50,233 --> 00:00:52,900

This model usually comes with a hard disk drive

10

00:00:54,633 --> 00:00:57,700

There's a hard drive port and a CD-ROM drive port,

11

00:00:58,266 --> 00:01:00,700

and the CD-ROM drive is aspirated

12

00:01:01,300 --> 00:01:04,833

At the time, this configuration was relatively high

13

00:01:06,133 --> 00:01:08,866

The machine has no independent graphics card,

14

00:01:09,400 --> 00:01:13,833

which makes it ideal for office and home video, not for gaming,

15

00:01:14,133 --> 00:01:16,566

and not for large graphics rendering

16

00:01:19,233 --> 00:01:22,400

Okay, this is the mainboard of the A1278

17

00:01:24,333 --> 00:01:27,366

Let's take a look at the A1398 mainboard

18

00:01:29,633 --> 00:01:34,233

It has an independent graphics card, CPU and PCH are separate

19

00:01:36,700 --> 00:01:39,033

There are 16 memory chips in the middle here,

20

00:01:39,666 --> 00:01:42,833

and another 16 memory chips on the back of the mainboard,

21

00:01:43,200 --> 00:01:45,500

for a total of 32 memory chips

22

00:01:47,666 --> 00:01:54,000

The common problem with this model is that the memory is easy to break and the graphics card is easy to break

23

00:01:54,866 --> 00:01:57,866

There are also two slots for solid state drives

24

00:01:59,166 --> 00:02:01,466

This model doesn't have a hard disk drive

25

00:02:02,166 --> 00:02:04,833

The top one is for WIFI/ Bluetooth module,

26

00:02:05,900 --> 00:02:08,466

and the bottom one is for solid-state drive

27

00:02:11,633 --> 00:02:13,633

In the middle here is the battery port

28

00:02:15,166 --> 00:02:18,300

Overall, the mainboard configuration is relatively high

29

00:02:22,000 --> 00:02:25,000

Okay, this is the mainboard of the A1398
