Startup Issues After Milk Spill - Need Advice

I spilled some milk on the table, and it entered my closed MacBook Pro M2 from the back. Initially, it showed an exclamation mark in a circle when it started up, but after some time, it failed to recognize the startup disk. Restarting worked, and it functioned normally afterward.

I let it dry for more than 24 hours in an upside-down position to drain any liquid residue. It worked fine again, but once it asked to choose the startup disk, and upon running a self-diagnostic test, it showed: 'There may be an issue with the fan.' Reference codes: PPF003, PPF004, PPF001.

What could be the issue, and what should I do?

You’re in a bit of a pickle! This is such a new system most independent shops haven’t seen it yet as most issues would still be covered under warranty. Did you takeout the extended service contract (AppleCare) if you did going to Apple would be your best bet.

While it’s similar to previous model depending on what got damaged (besides the fan) will require micro-soldering skills to fix the logic board and access to the needed parts.

Sadly, letting the system dry out was not the best direction. Milk and many liquids have acids and sugars or salts which can create corrosion and/short circuit things. Ideally, shutting the system down fully (not sleep) and keep the system cool which slows the damage until you can open the system to mop up as much as you can of what entered. Most people should find an independent shop with both MacBook Pro and liquid damage skills to go deeper.

Thank you for the insights. My MacBook is still under the limited warranty. After the issue occurred, I completely shut down the system and let it dry out for more than 24 hours. I only powered it on once to check and ran the diagnostic as it initially failed to identify the startup disk. Given this situation, should I proceed directly to Apple for a warranty repair, or is there anything else I should consider before doing so?

@barindersingh - Sorry, limited Warranty only addresses product defect, not liquid damage. The purchase of extended Apple Care coverage would have made the difference.

You’ll need to find an independent shop who has the needed skills.

@danj Thank you for your assistance and time. I appreciate the guidance. I need to find a good repair shop in Aberdeen, Scotland. If you have any recommendations or tips for finding a reliable service in that area, I would be grateful.

@barindersingh - Sorry I don't know of any in Aberdeen, take a look in Edinburgh maybe you can find someone there.

The next option is in Liverpool (Runcorn) but you likely will need to ship it to them TheBookYard

@danj I took it to a local Apple Store for a diagnosis. They found milk residue on the right-side fan, causing it to be blocked. Otherwise, there was no residue on any other part or the logic board. They said it should be okay to use for most tasks, except those requiring high fan activity.

What do you suggest? Should I consider replacing the fan or getting the fan cleaned at a local shop?
