Hello everyone, today we are going to understand which faults need to brush T2

2

00:00:05,433 --> 00:00:09,600

First of all, if the laptop with T2 chip cannot be turned on,

3

00:00:10,300 --> 00:00:13,733

we can try to brush T2 to see if the fault can be solved

4

00:00:19,566 --> 00:00:23,966

In addition, if there is an error in the process of upgrading the system,

5

00:00:24,900 --> 00:00:26,933

which leads to the failure to start up,

6

00:00:27,833 --> 00:00:29,733

we can try to brush T2

7

00:00:33,200 --> 00:00:35,700

It also includes the following faults

8

00:00:37,100 --> 00:00:43,966

If there is a black screen on startup, the fan does not turn or the fan is spinning furiously,

9

00:00:46,633 --> 00:00:53,066

and the status indicator is not on after MAC Mini starts up, we can try to brush T2

10

00:00:53,800 --> 00:00:59,000

Failure to boot from the booting file during startup, failure to restore the system,

11

00:00:59,733 --> 00:01:03,966

failure to restore the network, or failure to repair the firmware

12

00:01:10,666 --> 00:01:16,033

The Mac Pro indicator turns amber and flashes in the following order for four seconds,

13

00:01:16,700 --> 00:01:21,633

three short flashes, three long flashes, and then again and again

14

00:01:22,833 --> 00:01:26,000

We can also try to brush T2 in these cases

15

00:01:26,700 --> 00:01:32,733

When it wakes up again after sleep, the system desktop displays an error report,

16

00:01:33,433 --> 00:01:37,466

or the GUI does not respond, the APP does not respond,

17

00:01:38,733 --> 00:01:41,433

and the system does not respond after boot

18

00:01:41,633 --> 00:01:47,000

The fan spins at full speed for an instant and then stops in less than a second

19

00:01:50,266 --> 00:01:53,366

The computer shuts down and restarts automatically

20

00:01:53,966 --> 00:01:59,333

In these cases, we can try to brush T2 to see if we can solve the problem

21

00:02:00,133 --> 00:02:05,766

Also, the external hard drive is unresponsive, and the network has been disconnected

22

00:02:09,700 --> 00:02:13,633

In all of these cases, we can try to brush T2

23

00:02:16,266 --> 00:02:19,033

We'll talk about brushing T2 in the next video

24

00:02:19,333 --> 00:02:22,966

Here we only introduce which faults need to brush T2

25

00:02:25,800 --> 00:02:28,033

Okay, so that's all for this lesson
