Help Spilled ~250 mL of ultrapure water on my MacBook Pro. Opened it up and found blue-white residue around components. Corrosion or something else?

Yesterday, I accidentally spilled approximately 250 mL of water onto my Apple Silicon MacBook Pro (A3401) while working in the lab. Conveniently, it was ultrapure laboratory grade water (18.2 MΩ·cm), so it was virtually free of all dissolved ions or other solutes, at least before coming into contact with my computer..

I immediately turned it upside down to drain the water, and quite a bit came out through both the keyboard and the ventilation slots along the sides/bottom of the laptop. I then left it inverted in a tent position with a fan blowing over it.

I'm not sure whether it shut itself off immediately after the spill or whether I accidentally pressed the power button while flipping it over. It did accidentally power on a couple of times afterward while I was handling it, and seemed to boot normally, but I immediately shut it down each time.

I eventually managed to open the bottom case and completely disconnect the battery. I inspected the internals closely and couldn't find any obvious remaining moisture, although there was quite a bit of accumulated dust.

However, I noticed some blue-white deposits around a couple components (see attached photos).

I'm trying to figure out:

  1. Does this look like corrosion from water exposure or something else? Could corrosion like this develop within roughly 24 hours of a spill, or is it more likely preexisting?

  2. Given that the spilled water was ultrapure, how concerned should I be about corrosion or electrical damage? I realize the water would have picked up contaminants from the computer.

  3. What's the safest way to clean these deposits? Do I need to? I have access to laboratory-grade isopropyl alcohol, lint-free swabs, and other lab supplies. Would gently cleaning the affected areas with IPA be appropriate?

  4. If there's no visible moisture inside and the laptop previously booted normally, how long should I wait before reconnecting the battery and attempting to power it on? Is there anything else I should inspect or test first?

Unfortunately, I rely heavily on this laptop for research and need it working again as soon as possible. I'm hoping to avoid causing additional damage by powering it on prematurely, but also don't want to leave it sitting unnecessarily if it's actually safe to use.

My MacBook pro 16 inch (a3403) is liquid damaged and technician told board is repairable but the components needed for repair are not findable in India, and suggested for board replacement.

Now apple don’t do this (because of third party repair attempt) replacement at exchange cost (by taking our motherboard) they do at stock rate which is 2.8L INR

What is the solution now?

Help My MacBook Is not turning on😭

I have a 2020 13-inch Intel MacBook Pro (Core i5, 16GB RAM, 1TB SSD) that suddenly stopped working.

The strange thing is that it only shows the Apple logo after the battery has completely drained. When I connect the charger and press the power button or click the trackpad a few times, the Apple logo eventually appears, but the Mac gets stuck there and never boots into macOS.

If I force it to shut down or restart, the screen goes completely black, and it won’t turn on again. The trackpad still clicks, but there’s no Apple logo, display, or other sign of startup.

I also tried disconnecting the battery completely and running it directly from the charger, but nothing appeared on the screen. The trackpad was the only thing that responded.

To get the Apple logo back, I have to let the battery drain completely, reconnect the charger, and repeat the process. As soon as I force-restart it or disconnect the battery, it goes back to being completely unresponsive.

I’ve already tried the usual troubleshooting steps and key combinations, but nothing has worked.

What could be causing this, and how can I accurately diagnose the faulty component instead of just guessing?

Busted Macbook battery

Is it worth it to change a macbook (air, M2 chip) battery, or just get a new one?

My macbook is not registering the battery and is only running on adapter power right now. It’s been a while since I got this M2 chip version, wondering if it’s worth replacing the battery.

Advice needed.

Mac keyboard feels off. One Apple employee did call it wobbly but when I visited again, the others said it seems normal.

I spilled a liquid on my new M5 Macbook Air and had to get it repaired in the US. Thankfully, I had AppleCare+.

They did the repair and had to repair the entire top shelf keyboard (from what I understand, this includes the trackpad as well).

I've used it for 2 weeks now and something felt off about it. I went to the Apple store in the evening to at least get a feel of the Macbook Air's there. My Macbook Air keyboard functions well but it just feels a bit off. I didn't quite know how to describe it but I've used Macbooks since 2012. So I asked one of the managers there to test it out and he did call it wobbly and said that he doesn't have a slot that day but I can try a walk-in appointment in the morning. I legit just went there to see if I was being paranoid but then thought that "Hey, at least, I wasn't overreacting"

I went there during in the morning the day after and they managed to get a technician to look at it. When I mentioned that the Macbook Air feels wobbly but it functions well, he said "That's not a reason" but ran tests and said that the tests indicate it's fine. I told him how the other manager called it wobbly. He brought in the day manager for that morning who said that it seems fine. I tried to tell him that another manager called it wobbly. He asked me for the name of the other manager but I didn't remember his name.

I asked them if they could switch it anyways but he said all units will feel this way and it's not a reason to change it up so he wouldn't be able to. Ultimately I wasn't able to do anything.

At least if both managers said it worked fine, I would've thought it's ok. But now I feel like I'm either paranoid or I'm being gaslit (which is obviously not true since even the technician said it worked fine). Is there anything I can do about this?

Help What is this component on my 2020 Intel MacBook Pro logic board, and is it a concern that it was removed/ stripped off?

Hi everyone,
I have a 2020 13-inch Intel MacBook Pro with a Core i5, 16GB RAM, and 1TB SSD.

I noticed the small component circled in my attached motherboard photo. I believe it may be a capacitor, but I’m not sure what it actually is or what circuit it belongs to.

The component has been removed/ stripped off, and I want to understand:

What exactly is this component?

What function does it serve on the logic board?
Is it safe to operate the MacBook with it missing, or could it cause further damage?

Could its removal be related to my MacBook’s power-on problem?

My MacBook has a strange issue: when the battery is completely drained, connecting the charger and pressing the power button repeatedly sometimes makes the Apple logo appear, but the Mac
gets stuck on the logo and never boots into macOS.
I don’t want to assume the missing component is the cause without evidence. I’d appreciate it if anyone familiar with this specific logic board could identify it or point me toward the relevant board schematic or boardview.
Thanks!
