The rubber seals on the display bezel have become sticky due to aging.

How can I remove the sticky residue from the rubber seals and gaskets on the display bezel? I'd like to know what to do.

エアダスターでのホコリ除去なども試してみました。

元々このタイプの古いMacBookProはリコール対象だったことを知らず、Appleでキーボードの無償修理があったようですが、ちょうど調子が悪くなったタイミングがその期限の過ぎた後で対応できませんとのこと。

もし詳しい方で何か対処法をご存知の方がおられましたら、ご教示いただけるとありがたいです。

ディスプレイケーブルが途中で切れてしまっているので、ロジックボード上のコネクターを外し、ディスプレイアセンブリ自体を取り外しました。

その他にも、トラックパッドケーブルとバッテリーも外した状態です。電源を接続すると、起動音が鳴ります。usb-cポートにハブ経由で外部モニターに接続すると、映像信号自体はきているような気がします。ですが、画面のバックライトが光るだけで、何も表示されません。

もしかしたら、取り外した内蔵ディスプレイを検知していて、そこにメインの映像が出力されているのではないかと思っています。(主ディスプレイが存在しないはずの内蔵ディスプレイになっている？)

主ディスプレイを外部ディスプレイに切り替えるにはどうすれば良いでしょうか？

現状内蔵トラックパッド付近のコネクターも損傷しているので、キーボードやトラックパッドは使用不可能です。

ハブにwindows機で使っているキーボードを接続しましたが、おそらく認識されていません。

もしかしたら、Mac用のキーボードを接続すると認識されて、何らかのショートカットを使い、操作出来るのかな、と思っていますがそう言ったことは可能でしょうか？

2011年9月にApple StoreでMacBook Airを新品で購入しました。そしてトラックパッドが、2012年9月に反応しなくなったため、Appleで交換しました。この修理以来、問題は発生していません。

今朝は問題なく動作していたのに、今日の夕方、キーボードとトラックパッドが全く反応しなくなりました。キーボードで動作するキーは、電源ボタンだけです。システム設定では、トラックパッドが接続されていることすら認識されなくなりました。

インターネットのフォーラムで、MacBook Proで同じような問題を抱えた人がいて、それはバッテリーの下にあるリボンケーブルが緩んでいたからだという話を読んだことがあります。しかし、この問題がMacBook Airモデルでも発生しているという情報は見当たりません。もしかしてこれも同じ問題でしょうか？

仕方が無いので、自分でロジックボードの交換をしたいのですが、どこでロジックボードを入手することが出来ますか？

中古でも販売していることを見かけることがありませんので

入手手段を教えて頂けますと幸いです。

Currently I am using imac 5K mid 2017, but since usb - c failed, I brought it to an APPLE authorized service provider, but I was refused repair.

Since there is no choice, I want to replace the logic board by myself, where can I get a logic board?

Because I do not see what I sell in second hand

It would be greatly appreciated if you could tell me how to obtain it.

I have MacBook Pro M4 A3112.(Nov'24). this is my first Macbook.

Initially display screen had some damage, so got the screen replaced and i notice both Wifi and Bluetooth has stopped working.

I took back to the repair guy who helped to replace the screen, but he has no clue why Wifi and Bluetooth are not working.

please find the attached the screenshots and photos I took as part of initial diagnosis I could do.

Please advise, what could be the issue and how to resolve this ?

Thanks

Hi @danj

I did reformat whole Macbook and reinstalled OS. Seems issue still persists.

I connected the MacBook to my router using Rj45 cable with the help of connector so I can access wired network connection to internet.

However I tried to do offline diagnostic and I got the error CNW001 . Have attached screenshot.

Power charger wasn't connected to macbook when I ran the diagnostic so the error PPP020 can be ignored in the image here, as I see the MacBook is working fine when charger is connected.

Let me know what option i have to resolve this CNW001 error.

I am using wired connection for Internet for now, not a substantial solution.

Thanks

RB

I used an Ethernet cable and was able to connect to internet.

The pic was taken with ethernet cable on !

I researched a lot online and did the following:

• Disabled Energy Saver - Automatic Graphics Switching on both Battery and Power Adapter mode
• Disabled Spotlight indexing for specific types of content and also added folders like “/System” in the Privacy settings
• Reset the System Management Controller (SMC)
• Performed the Apple Diagnostics test (ADT - some older websites called it the Apple Hardware Test - AHT) and had no issues come from that.
• I also use Google Drive’s “Backup and Sync” and do lots of web development with `node_modules` folders, that can have 10s of thousands of small files which I think results in CPU churn. I’ve disabled it now.
• Shut down the computer and turned it back on. Still get same issues with the external monitor.

Now with no external monitor plugged in, every once and a while the kernel_task rises up to 300% and sometimes rarely to 500%. I’m curious if it is a software thing or a hardware thing. To me it seems more like a software thing.

I use VS Code for programming which can have a lot of background tasks, same with using node/npm which can probably be doing lots in the background. I also run iStat v6.30, and sadly I have only 21 GB of free space on my HDD (out of 500 GB…). Often I also have Slack open, and I know that’s a web app using Electron to run as a desktop application, which can be notorious for performance.

Often the fans can run high as well. I often suspect it is either due to the VS Code/npm/node/Slack thing, or kernel_task, or maybe something else I’m unaware about.

When checking memory usage via iStat, I can see that kernel_task is using 1.61 GB (oof, Firefox is using 6.36 GB).

Things I haven’t tried yet:

• Cleaning out more free space from HDD
• Using plain HDMI cable into the HDMI cable port
• Taking MBP apart and cleaning any potential dust

Has anyone had similar experience with this issue and how to address it?

OS: 10.13.6

Processor: 2.5 GHz Intel Core i7

Memory: 16 GB 1600 MHz DDR3

Recently bought an early 2015 MacBook Pro 13" which had light water damage.

Opened it up and gave it a quick clean (rice everywhere...)

Only problem I can see is the MacBook can see the battery but wont charge and says it needs replacing (only 17 cycles)

The MacBook only works when connected to the charger.

Now I have a 2014 MacBook Pro 13" which functions normally.

Can I plug that battery into the 2015 model to test that it definitely is a problem with the battery before buying a replacement?

Don't want to waste money buying a replacement battery if that wont fix the issue.

Cheers!

The new logic board arrived and I have installed it in the mac. Everything ok until this point.

Where I started to have problems ....

As the built-in display is cracked I can't do anything, but I knew that from the start. So, I connected the macbook air to the external display and the problems started to happend here.

I set up the macbook the following way:

- I connected the external power adapter, connected an external keyboard and mouse and connected the external monitor.

1 - I can close the lid plug/un-plug the monitor, do a million of different combinations, but it didn't wotk work. The clamshell mode is never activated.

2 - I tried several shortcuts to extend the monitor and nothing.

3 - I shut down the mac, closed the lid, removed the power and put it back.

The mac started automatically and I have image on the external monitor, but it's extended instead of mirrored, so when I press "D", it won't show the menu.

Opening the lid reveals the LCD black. It's, basically, off. Removing the cable of the external monitor does nothing, the built-in display continues off until I reboot again.

I don't mind this, since it will be a headless computer.

Question: how can I force the external display to be the main one, so I can configure the computer?

The previous owner formatted the ssd , so I get "?"and cannot go any further regarding booting the system.

Kins regards,

Pedro
