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？

Not much got everywhere, but some of it appears to have gotten stuck underneath at least 3 keys; mainly the "T" & "Y" keys, as well as the screen-brightness reduction key in the top left of the keyboard. The keys have since become stuck & it's become a bit harder than usual to push them down. I know it's possible to remove the keys on older models for cleaning, but I'm unsure how to go through with it/if there's a different process for the new 13" Air. Any help would be highly appreciated <3

As described in the title I can only charge my MacBook Air 2020 with an old (extremely slow) USB-A to C charger, I don't exactly know when the issue started because this MacBook was gifted to me not too long ago, but I think there were some smaller issues with charging prior to this one.

If anyone has any insight, it would be strongly appreciated!

Here’s the full history:

I spilled coffee on it. I took it to a shop and they told me they couldn’t fix it. After about a week I opened it up myself and left it open to dry for another week. Now, in about week three, I started putting it back together — and to my surprise it turned on.

So it’s partially alive, but I have a few related issues I’m trying to sort out:

When I first booted it during reassembly — before screwing the trackpad bracket down — the trackpad worked and I could move the cursor and check the battery percentage. After I screwed everything down and rebooted, the cursor stopped moving and hasn’t come back.

The battery connector is plugged in and locked with its metal locking arm, so that one seems fine. The connector giving me trouble is a small board-to-board (mezzanine) connector near the battery connector — I believe it’s the keyboard/trackpad flex. It has no ribbon and no latch; the two halves just press together. When I press it down it clicks and holds for a few seconds, then pops back undone. I have not used any glue.

On power: the machine shows one fixed battery percentage that never changes, and it shuts off immediately the moment I unplug the charger. It only runs while plugged in.

What I’ve tried so far:

• Reseating that board-to-board connector multiple times

• Confirmed the battery connector is seated and locked

• Verified I haven’t damaged the battery connector’s locking arm

What I’m trying to figure out:

1. Why that board-to-board connector won’t stay mated — alignment, a bent/cracked contact from the spill, tension from the bracket/screws pulling the flex, or corrosion damage?

2. Whether the “shuts off when unplugged / stuck percentage” means the battery is dead/failed, or something related to the spill.

3. Whether tightening the trackpad down is what’s unseating the connector, and how to get it to snap and hold.

Given the coffee spill, I’m also wondering if I should be looking for corrosion on these connectors or the board.

Details:

• Model: MacBook Air M1, A2337 (EMC 3598), Late 2020

• History: coffee spill → shop declined repair → dried open ~2 weeks → reassembling in week 3, powers on

• Battery connector: seated and locked

• Problem connector: keyboard/trackpad board-to-board (mezzanine) connector, won’t stay mated

I can post close-up photos of the connectors and board on request. Any guidance appreciated.

We thought the issue was a bad SMC, We replaced the SMC, Connected the charger, Brief fan spin, no chime or boot. No water damage, clean board Technician cannot find any shorts. The issue remains even with no KB connected. We have reset & programmed the SMC with SMC tools / Unable to reset PRAM etc...... Only with SHIFT+OPT+Power I got it to boot into the system, fan at normal speeds, power button does shut it down....But the system Prefs wont load and it is dead slow. I have used 2 new keyboards shells and 2 good TP cables yet still the same, and with a fresh Monterey installed drive. Diagnostics no issues found. The KB & TP are functioning fine (Except to power up). In recovery mode the terminal sudo nvram -c command is not found. Firmware password is off. @danj @oldturkey03 What can be our issue here?

System Firmware 489.0.0.0.0 correct for Monterey.

SMC Version 2.27f2

No Audio devices are detected with 2 I/O boards, which maybe our issue? Although it did chime once before.... Charges battery OK .....I eventually have successfully clean installed a copy of Monterey on the unit but everything is still the same.... At least I thought so but it has stuck on 12 minutes remaining for quite some time now, I will have a sleep and see if it finished when I wake up.... And as expected it is stuck at under a minute.....

When I click restore, it gets on the 4th step and stalls, then I get a message saying:

“The System cannot be restored on this device.

Unexpected device state 'DFU' expected

"RestoreOS (Probably forced into DFU

mode externally)“.

I have used different USBC cables and keep getting the same message.

I have a MacBook Air M1 2020 (A2337) with a keyboard issue. The 3, E, and D keys not work. These three keys are aligned vertically on the keyboard. I want to mention that this is how I purchased the macbook with this problem. I thought I could clean each key individually and solve the problem, but it seems my idea didn't work.

What I have already checked:

• The MacBook has never had any liquid damage.
• I removed the individual keycaps and inspected the mechanisms underneath.
• The rubber domes and key mechanisms look perfectly fine.
• There are no signs of corrosion or dirt.
• I opened the laptop and inspected the inside, which is also very clean.
• I disconnected and reconnected the keyboard flex cable, but the issue remains.
• All other keys on the keyboard work normally.

Since the affected keys are in the same vertical line (3, E, D), I am wondering if this could be a keyboard matrix issue or a failed row/column circuit.

Has anyone experienced the same problem on an A2337 MacBook Air M1? Is there any repair possible without replacing the entire keyboard or top case?

Any advice or schematics would be greatly appreciated.

Thank you!
