iMac Intel 27" Retina 5k Display: iMac 5K mid 2017のロジックボードの故障(iMac 5K mid 2017 logic board failure)

Sun, 10 May 2026 20:33:53 -0700

現在、imac 5K mid 2017を使っているのですが、usb-cが故障したのでAPPLE正規サービスプロバイダに持ち込んだところ、修理を拒否されてしまいました。

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.

MacBook Pro 13" Touch Bar 2018: MacBookProキーボードの対処法について

Sun, 10 May 2026 20:33:09 -0700

SMCやNVRAMのリセットをすると使えなかったキーボードが一時的に使えるようになるのですが、すぐに機能しなくなってしまう場合はやはり修理しかないのでしょうか？（何度試みても）

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。

MacBook Air 13" Mid 2011: キーボードとトラックパッドが応答しない原因は？

Tue, 14 Sep 2021 22:28:54 -0700

この質問は、英語のアンサーフォーラムで広く利用されています。そこで、この質問と回答を、日本語コミュニティーでも公開します。

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？

Retina MacBook 2015: MacBook Retina 12" (2015) stuck at 5V 0.08A after battery drained comp

Wed, 10 Jun 2026 17:20:41 -0700

MacBook Retina 12" (Early 2015, A1534) was working normally before the battery drained completely.

The next day it would no longer power on.

Using a USB-C power meter, it only draws 5.05V at 0.08A and never negotiates a higher voltage.

I have already tried:

Different chargers and cables

Holding the power button

Leaving it plugged in for several hours

Is there anything else I can try before considering motherboard repair?

MacBook Pro 16" 2021: Machine will not power on - charge light pulses

Tue, 09 Jun 2026 18:32:55 -0700

My kiddo has my old Macbook Pro 16" 2021. They came home from school the other day and opened it up, with no response. They tried plugging it into a charger, but it still wouldn't turn on. Now, the charger they were using was apparently a little chromebook charger... I plugged it in with magsafe to the charger that came with it--the light came on green. I tried holding the power button down for 10 seconds, but the only thing that happened was that the green on the charger turned off, then went to orange. I tried pressing the power button to no avail. After a little bit (maybe 30 seconds?) the charge light smoothly turned off for about a second, then turned back on. This pattern repeated until I unplugged it and plugged it back in. Every time I tried to power it on, I got this pulse pattern, orange on for awhile, short off, back orange for a shorter time, then back to short off, short orange.

I left it plugged in overnight, and the light changed to green at some point, no pulsing. when I tried to turn it on, still nothing on the screen, no caps lock light, no trackpad clicking, but the charge light turned off for a short bit (1s?), then orange for a little longer (10s?) then back to green, which held for about 30s before flipping to off, then orange again, then back to green.

Anyone have any ideas what might be wrong? I'll probably try taking it to the apple store, but it's out of warranty and I suspect all I'll get from them is the "yup, we can send it in for a $700 diagnostic fee."

MacBook Pro 14" 2025 (M5): Corrosion on right connector. Next to HDMI

There seems to be some water damage on the right side usb-c connector. Is it possible to have it changed? Is it removable or does the logic board have to be completely changed. The corrosion is just on the connector pins on the outside.

My Macbook air m1 a2337 is having LCD issues. On startup & login, the LCD is fine.

Then when i click on an application, that's when the screen quality turns into this:

I have the IFIXIT Pro Tech Toolkit. Im just looking for someone to identify which part inside is the issue? Apparently it's one of the connectors. Also if you can identify the part, where will it be located & a picture example. If there's a video that's even better. This is the only issue. The macbook runs fine.

MacBook Air 13" Early 2015: Wont turn on after randomly turning off

Tue, 09 Jun 2026 08:23:33 -0700

Ive bought a macbook air A1466, used to have a macos device for messing with my older iphones.
Ive been using it for a month and a half and when i turned it on last morning it booted up, i entered my user password and went away. when i came back it was on the desktop and it randomly went blackscreen.
I thought it just fell asleep but pressing keys and touchpad nothing happened -it wont turn on anymore, no chime, no fan, nothing. I tried pram reset(but no apple logo when booting so didnt really work..), smc reset multiple times.
Unplugged battery, also took it mostly apart, put everything back, checked connectors.
Only issue is that the bluetooth-airport card's one of the connector wont go on, but that has been like that since i bought it and it worked. Also the screen has dark spots and light spots -probably liquid damage(some extra info). But liquid indicators arent red on the board or anywhere... but theyre yellow-ish..??
Also battery health was like 39% (in coconut battery), but as i said it worked completely fine before, and unplugging the battery from the board still didnt work. Magsafe charger is orange, but after a bit turns green.

What can i do to make the machine work again?

iMac Intel 21.5" EMC 3068: Will this Adhesive tape hold, or should I reopen it and redo it?

Tue, 09 Jun 2026 01:56:17 -0700

Hello I have ordered the iMac 21,5 2017 HDD replacement kit. I replaced the HDD with a crucial SSD and cleaned off the old adhesive and with isopropal cloths aswell.

Turns out iFixit sent me one too many adhesive stripes of the same type and left the other one out. Iam missing the 02 adhesive strip and have the 01 adhesive strip two times.

I have now cut it in proper form and was wondering if I would have to redo this job once ifixit will provide replacement.

I couldnt leave it open and the glass laying around as I got a little kid at home.

here are some Images:

looking forward to your replies. I really dont want to do this again. It seems like it would only be 2/3% of the adhesive strip missing, I personally think its fine as it will stand on a desk and be rarely touched.

Thanks in advance!

MacBook Pro 14" Late 2024 M4: Screen Replaced, But Wifi and Bluetooth stopped working

Mon, 08 Jun 2026 05:06:19 -0700

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

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

The pic was taken with ethernet cable on !

MacBook Pro 13" Unibody Early 2011: Charging and Boot Issue

Sun, 07 Jun 2026 15:03:14 -0700

I have a MacBook Pro 13-inch Early 2011. I installed a battery in it, but when I connect the charger, the MagSafe LED turns green, and the MacBook emits a repeating sound approximately every half second. At the same time, a white LED turns on and off repeatedly, and the MacBook does not start.

However, if I disconnect the charger, then press and hold the power button, and while holding it reconnect the charger, then release the power button after a few seconds, the MacBook powers on normally. The problem is that the fan runs at a very high speed, and the green MagSafe LED turns off, although the charger continues to power the MacBook.

I would appreciate it if someone could explain the cause of this issue.

Thank you very much.

Here is the screenshot as requested.

Please note that the MacBook does have a battery installed 😢

MacBook Pro 15" Retina Display Late 2013: Computer unexpectedly shutting down after battery replacement

Sun, 07 Jun 2026 00:26:53 -0700

I recently replaced my battery with an ifixit battery. I calibrated the battery per the instructions, but the computer is unexpectedly shutting down while I still have significant battery life remaining (i.e. 62%). It will restart immediately and will sometimes run for a decent amount of time and sometimes shut down again immediately. It seems to run fine while plugged into the power adapter.

MacBook Pro 14" 2021: Can I replace or fix the microphone?

The microphone on my M1 Macbook Pro is very muffled.

After some investigation, I'm fairly sure the problem is a blocked grille. But it's hard to identify which (if any) of the hundreds of dimples on the left-hand side are actual holes and therefore need cleaning. Is there any information on this?

MacBook Pro 13" Two Thunderbolt Ports Late 2020: MacBook 2020 battery stuck at 1% after repair (battery data problems?)

Sat, 06 Jun 2026 05:25:11 -0700

A few months ago the battery died and I replaced it. Unfortunately the repair did not work. When I turn on the Macbook the fans come on full power, and the battery claims to be at 1% with "Service Recommended." There was a brief moment where the battery was detected a few weeks later, but after a factory reset (I bought the laptop off a friend), it has returned to being stuck at 1%.

The Macbook turns on only when it is plugged in, but if I unplug it while it's on, it can stay on for hours (with the fan working at full speed).

Here's what I've done so far:

1. Tried a whole bunch of combinations of draining and then recharging the battery, restarting in recovery mode, etc.
2. Tried two other battery data cables from seemingly reputable companies - I even tried a tape trick to try for a better connection, it did nothing in my case
3. Got a second replacement battery from ifixit (they kindly sent one for free)

So far, none of these attempts have made a difference.

To me, it seems to be an issue with the data transfer from the battery to the rest of the computer, but I think I've ruled out a good number of culprits. Usually, I'm able to figure these problems out on my own, but not this time. Any help would be highly appreciated!
