Hello. I am John Schindler.

I replaced the battery of my MacBook Pro today, but a 'service recommended' message appears.

In the Coconut Battery program, the battery life is 100% and there are no problems.

Is there any way to solve the symptom of this problem?

안녕하세요. 저는 존쉰들러입니다.

오늘 맥북프로 배터리를 자가교체를 했지만, '서비스 권장됨' 안내표시가 뜹니다.

코코넛 배터리 프로그램에서 배터리 수명이 100%이고 별 문제가 없어보입니다.

이 문제의 현상을 해결할 수 있는 방법이 있습니까?

My 18 month old, MBP M4 Pro screen died. Took it to the ""Genius Bar"" to be told I had a faulty display!! Apparently this is quite a common fault with this model, my "genius" telling me he alone repairs at least four a day!!!!! If you're using this as intended and on a live event or important gig it may be worth having a spare USB C display to get you out of trouble (Command +F1 to switch).

The really annoying thing about the repair was that they wouldn't work on it unless it used the latest iteration of Mac OS, and threatened to wipe my hard drive before basically undoing some nuts and bolts and cables to replace the screen. I had to upgrade there and then to save the hassle of a later install from Time Machine.

This would've cost £623 to fix (I had AppleCare) BUT as I'm in the UK this was considered a 'Consumer Law Repair' which is up to 6 years in this country and also free.

Since then, the system has exhibited the following issues:

1. The Dock magnification is glitching; it only magnifies the icon previously hovered over rather than following the cursor.

2. I am unable to launch any applications using either the trackpad or an external mouse.

Hardware context: The laptop has 16GB of DDR3 RAM and a 250GB SSD (with 195GB free). It is currently running without a battery and has one blown speaker.

Could the damaged camera cable be causing these UI and input issues, or is this related to the OCLP installation? If it is a software issue, how can I troubleshoot or fix this?

I have a 2" vertical strip on the left side of my screen that all of a sudden turned darker than the rest of my screen. It's tinted darker. I can still see the screen, but it flickers some, and at certain times I can vaguely see the browser's bookmark bar in the tinted section at the top. I can mirror the screen onto my TV, and the tinted strip isn't there. I did some research and think it may be the display cable. Does anyone have a repair guide for something like this?

I now see six holes in the logic board where the cable is supposed to fit. I can line them up to the cable but can't connect by pushing straight down. I have attached photos showing the condition of the board and the cable end.

Can someone confirm if the socket has been torn off the board? If so, is this repairable through micro-soldering, or does it require a logic board replacement? Not great res, I apologize.

Also, is this cable bad?

I’m having a strange issue with my MacBook Pro display, and I’m hoping someone can help.

A few weeks ago, I noticed a couple of thin green horizontal lines starting at the bottom of the screen. Since then, more colored lines (green, pink, and other colors) have gradually appeared, and the number of lines keeps increasing day by day. The issue seems to be spreading upward from the bottom edge.

The strange part is that my MacBook has never been dropped, the display has never been hit or pressed, and I’ve never accidentally closed the lid with an object inside. It has always been handled very carefully.

Here are a few details:

• The lines are only on the built-in display.
• They started from the bottom and are slowly increasing over time.
• There was no single event that caused the problem.
• Restarting the Mac doesn’t fix it.

I’ve attached a photo of the display.

Has anyone experienced something similar?

• Is this likely a failing LCD panel, display flex cable, or display controller issue?
• Is there anything I can try before replacing the entire display?
• Could this happen without any physical damage?

Any advice or suggestions would be greatly appreciated. Thank you!

Troubleshooting steps - I've basically done everything software wise, so I know it's hardware. Chat GPT seems to believe it's the backlight fuse that may have blown due to liquid entering.

Anyone have a hunch on what's happening? I know liquid is difficult, as I've actually worked at an Apple Store as a technician. This was a used purchase and I'd rather not spend a whole lot fixing it, but I'd like the backlight to work.

I do not have soldering equipment or a microscope, but I'm comfortable disassembling and stuff at home (I've replaced thousands of phone batteries and displays, and I build computers as a hobby). Thanks!

Original symptoms were short battery life and touchpad physical clicking not working. I bought a replacement battery and touchpad.

Battery was definitely bulging and putting pressure on the touchpad. I swapped out both and when booted back up - no mouse movement or clicking at all from the touchpad. External mouse works fine, so I went into system preferences and then Touchpad. It said "Touchpad not detected" or something along those lines and had a spinning circle indicating that it was searching for bluetooth touchpads.

So I opened it back up and swapped in the original touchpad - mouse movement but no clicking. But still, system preferences says it doesn't detect a touchpad (I was hoping to at least turn on tap to click.)

So, what am I missing? Is there some extra step to set up the touchpad with the OS? Does the lack of movement on the replacement pad mean that it's DOA?

Thanks for any help!

I have a 16" Macbook Pro 2021 (A2485) that has a cracked screen but I am able to buy a complete identical model laptop 'skeleton' (minus its original logic board) for less than the price of the repair at Apple.

If I transfer the logic board and Touch ID from my 'working laptop' with the cracked display, into the donor laptop shell, will everything work as normal or will I come up against a few issues?

Thanks!

About a week ago these visual issues have started, which I have assumed were linked to the flex cable that goes into the display assembly itself, making it impossible to fix.

The issue is triggered either by pressing the plastic bottom bezel at the left corner, or by moving the orientation of the screen.

I put my laptop for sale on a local marketplace, and someone called today saying the same happened to his 16" M1 Pro. He told me a repair shop has successfully repaired it by replacing a ribbon cable hidden behind the said plastic bezel strip, and the repair cost him very little money.

Does anyone have any idea about what exactly could've went bad so I can explain it to technicians that would attempt a repair for the laptop?

So far, I've just been quoted a full display assembly replacement costing from 800 to 1000€, which isn't an option. Thanks

- Hard to see on camera, but that region of the chin bezel > display seems to have kind of a bloated/warping effect.
