MacBook looks dead after possible water damage.

A few days ago there was very heavy rain where I live. My mbp was in my backpack (which should be water proof). When I arrived home I noticed some water on the side of my mbp. I cleaned it of and started using it. After 5-10 minutes the computer crashed, so I rebooted it and it started up until the login screen and than crashed again. after that it crashed 2-3 more times without reaching the login screen. After that it won't turn on.

A few things I already found are that when I plug in the power adapter, the light goes from green to red. And when I perform a smc reset, the light on the charger flashes.

Today I opened it for the first time, and noticed that te moist indicator to the left of the fan was red. Since this voids my waranty, I would like to fix it myself.

Does anyone have any idea where to start?

Kind regards

Jan

One thing to consider is what credit card you used to purchase the computer originally. Many credit cards (American Express, for example) include accident protection for purchased items, which may cover the cost of an Apple Store repair. It's worth checking to see what coverage your card gave you.

I'm kind of a nut for preserving whatever warranty you have. You paid Apple for that warranty (if you got the AppleCare extended 3-year warranty, you paid a lot for it), and it's worth getting what you paid for if you can. Even though Apple doesn't warranty "accidents", Apple will often keep the warranty open if the accident is repaired by the Apple Store or by an Apple Authorized service provider at your expense.

If you have an Apple Store handy, it's worth trying to take it in to the Genius Bar even though they may void the warranty. They're employees of a big rich company, and they know their system, so they know how to turn it to their advantage. Sometimes they'll feel sorry for you, and give you things you're not legally entitled to. In any case, if Apple does the repair for you, your warranty will be preserved, and the work performed will carry a 90-day warranty even if it's out of your basic warranty period. Since Apple has a ready supply of tested parts, they may be able to do the fix cheaper than you can. At least get an estimate; if you don't ask, you don't get.

But if you want to do the work yourself, and you're prepared to give your warranty up for lost, here are some places to start:

Electronics Water Damage (applies to any kind of liquid spill)

The usual advice in these cases is to:

  • disassemble the system
  • wash all the circuit boards (logic board, I/O board, MagSafe DC-in board, SSD, maybe the Airport/BT card) in purified alcohol or distilled water
  • dry completely
  • reassemble (being careful to apply the heatsink compound correctly to the logic board and heatsink)
  • replace the battery
  • charge the replaced battery overnight
  • attempt a restart

My guess is that when you disassemble the computer, you'll find that other liquid sensors have also been hit. This will give you a better sense of the range of the water's impact.

In general, a liquid spill typically harms the battery; replacing the battery is a pretty standard thing. Since your MBP was closed inside your backpack, it's possible that your keyboard is unaffected. Once you're able to start the computer again, it's a good idea to open up a text document and check each key (shifted and unshifted) to make sure they work correctly. Otherwise, you may need to replace the keyboard and/or top case.

Thanks for the reply. I dissasembled it and let the battery charge overnight. Now the battery is full, but it still won't start. At this point I wanna go to the genius bar, but I need a backup of my ssd. Is it possible to put my dead mac in target disk mode?

I don't think so, but you can try. Target mode shouldn't work if you can't power up the system. OtherWorld recently released a USB3 enclosure compatible with 2013+ MBP SSDs. You could pull the drive, put it in the enclosure, do a backup then reinstall the drive. My own gut instinct with SSDs is that I always maintain Time Machine backups. I had a talk with some DriveSavers engineers about SSD reliability that makes me jumpy about not having a restorable backup on a platter drive...It's possible that the full battery report is bogus. The battery fills up nearly half of the 13" chassis, and liquid can go just anywhere; it could have hit the relevant sensors, and is now producing a goofed-up reading.

If you get to the DIY point, you can try removing the battery and powering it up just from the AC adapter. Sometimes, Apple laptops won't start if they can see the battery but they detect that the battery is drained; if the charge sensor is acting up, or the battery is really dead and the computer isn't detecting that, it may not even power up from the charger. If you disconnect the battery completely, that should force it to start from the charger. If it won't, then it's possible the MagSafe DC-In board is damaged, so that's the next thing to swap out.
