Can SSD be replaced?

My SSD storage is a bit small, I would like to change a little bigger drive, can be replaced?

一、ssd是否可以拆换

二、是否可以使用不是苹果定制版的ssd

三、例三星的ssd接口是否需要转换器

I asked Chat GPT:

• SSD power rail missing or unstable
• Corrosion/liquid damage around SSD connector
• Broken SSD PCIe data lines
• Clock/reset signal issue
• PCH communication fault
• SMC-related power gating issue

The “33 KB device” symptom usually means Recovery only sees its own RAM disk or recovery environment, not the actual internal SSD

1. Measure SSD power rails
   You should verify:
2. PP3V3_SSD
3. SSD enable signals
4. PCIe reset

33kb Volume only is displayed. Unable to partition or erase.

Attempting to install Catalina on a unit that previously had Catalina installed.

Ignore the other drive that is highlighted as that is my external multi installer drive.

It is the same thing with another SSD except the other drive isn't listed at all, just the base system. Failed drives?

Windows was never installed on either of these drives, this has been confirmed by previous owners.

This is relevant to my other post 3x 64 GB SSD - Q Folder @ Boot

UPDATE: Tried with a Windows installer.

SSD (1) Gave me this:

SSD (2) Gave me this:

After hitting OK it rebooted to the Q folder.

Chap GPT suggests the following.

• SSD power rail missing or unstable
• Corrosion/liquid damage around SSD connector
• Broken SSD PCIe data lines
• Clock/reset signal issue
• PCH communication fault
• SMC-related power gating issue

Then it started turning off every 30 seconds, same thing closing display and opening again fixed it. At this point, connecting to an external monitor worked fine. So on the external monitor I could use it like regular (with mirrored or extended screen).

Then I restarted, tried a bunch of things on the https://support.apple.com/en-ca/HT210905 and https://www.macbookproslow.com/fix-black....

I never got into safe mode or knew if things were working, but I tried all the keyboard combinations. Late into the night, it started working and then I used the Macbook regularly, I went to sleep happy that it was fixed.

Now I woke up and the screen is not working at all, not even showing the apple logo which it was last night. Also, it's not working on external monitor either. I can still see the external monitor and the mouse but it's a black background. The backlight is working and the keys and everything seem fine.

Very frustrating and I'm not sure what to do :(

However, I am curious if anyone else has seen this issue, or experienced it happen to them first hand? It does seem that people are discussing it on Apple's Community Page, so at the very least I know that these are not isolated issues.

I swapped over the keyboard / TP cable 4x with new parts

Changed 3x complete keyboard assemblies (All with new keyboards)

Using new track pads / Clean install Monterey 12.7.6 and was able to complete setup and all seemed OK but I noticed the keyboard response was delayed...... now next to nothing going on when I reboot and try to login.

Keyboard isn't responding and when it does it is 5 seconds late in displaying 'some' keys. Cables are seated and latched correctly etc. Connector looks clean (I have cleaned it out, no dirt and dust under the microscope) I have even put the SSD into another unit to check the OS, ALL fine!. This is driving me nuts.

Must be a board issue..... but it is working fine other that the KB issue.

It is 100% NOT in the dreaded CPU safe mode state. Any ideas?

UPDATE: It magically fixed itself. (Stuck right side command key!).

I didn't get the display with the machine since it was toast—the T-CON board was still mounted in the top case and all the cables were totally ripped, hinges were still screwed in as well, just none of the rest of the display

Surprisingly, the thing still boots. I didn't even have to do anything. I can get into it no problem. Have recovered data for said friend.

But since said friend doesn't want it back, I wanted to get some use out of it. I need to get some pictures for the MacBook Data Recovery Guide I've been working on for Share Disk Mode steps and this is the only Apple Silicon Mac I have access to.

It will not show the startup options screen on the external display I have connected. It may be on the correct menu, but I would have no way of knowing since it doesn't output the primary display, only the secondary display in an extended setup. All I get is a black screen and mouse pointer if I manage to get the pointer on the second screen. Oddly, the internal display is still "detected" when I'm in OS. Maybe that's normal? But I don't even have the eDP cable connected.

Powering on never gets me an Apple logo even if it's booting, and I never see whatever was supposed to be on the primary display until it gets to OS where I have it set to mirrored mode.

I have tried various terminal commands I've found, which all errored as invalid (they all reference NVRAM which is handled differently on Apple Silicon Macs). I tried triggering lid closed signals via magnets. I've tried clicking blindly, and pressing keys in some combination that might make sense for selecting the Options button. But no change.

Please help me so I can help you.

UPDATE 03/19/2023: I have messed with this a whole bunch more, just for the sake of science, but still to no avail. I have seen others who mention this sort of behavior on Apple Silicon Macs. The internal display is still detected even when it is not present.

So I went into science mode. I powered it up and measured IPD_LID_OPEN_1V8. Which measured almost 1.8V on the nose. Neither of the hall sensors containing components are even connected.

Electrically speaking, I'm willing to bet it still thinks this display is detected. And it's open. But I'm not sure where the initial detect signal or logic comes from. So. I thought. I wonder what happens if I just break the line for the aforementioned Lid Open signal. So I removed RR203. This broke the path for this 1.8V signal to be transmitted elsewhere.

Now when I connected power to the board, it thinks the lid is closed, so it won't auto power on. I can probably force a shut signal by shorting that line after I'm sure the machine is on. I can get it to power on by shorting pads, but it acts weirder than it was before.

I will probably see what happens if you break some of the enable lines, or power rails for the display.

Screen shows no sign of these patches when turned off

There may be an issue with the fan ppf003

There may be an issue with the camera ndc001

The fan is running flat out, using Mac fan control app I can see the computer is reading the RPM correctly as it fluctuates up and down in RPM slightly and all temperature sensors appear to be working. Using photo booth I can confirm the camera is working perfectly too.

I have done nvram and pram reset but still same two errors. I read online that if the camera is not seated correctly it will cause the fan to run flat out so I double checked the connector for it and it's in nice and snug. I've removed it and reinserted it 3 times, same error but still camera works perfectly in MacOS.

How can I tell the Mac the camera is working fine and to dismiss this error?

On the slight chance I have somehow damaged the fan I have ordered another one although it seems to be fine from everything I can see. I have tried to reseat the fan cable multiple times too.

But I’m quite confused about where is it located precisely.
