Liquid on a MacBook isn’t always the end, but what happens in the first hour makes a big difference. Most of the damage comes from current flowing through wet circuits, and from corrosion that keeps working for days.
Right away
- Unplug the charger and shut it down. Hold the power button if needed. Don’t wait to save your work.
- Don’t turn it on again to “see if it works”. Each power-on with liquid inside can burn components.
- Turn it upside down in a tent shape so the liquid runs out of the keyboard, not into the board.
- No rice, no hair dryer. Rice doesn’t pull liquid out from under chips. A hair dryer pushes it further in and can warp parts.
If you are comfortable opening it
- Remove the bottom case and disconnect the battery (on most models, the battery connector or its cable on the logic board). This is the most important step.
- Take photos so you know where liquid went.
- Leave it open to dry, but drying alone doesn’t stop corrosion. Sugar, coffee, juice and salt water leave residue that conducts and corrodes.
The real fix
The board needs to come out and be cleaned: isopropyl alcohol (99%), a soft brush, and ideally an ultrasonic cleaner, then thorough drying. Then check for damaged components under a microscope before powering on. If you’re not set up for that, a board repair shop is the right call, and the sooner the better.
Data first
If the data matters more than the laptop, say so when you ask for help. On recent MacBooks the storage is soldered to the board and encrypted, so the board has to work to get data back. Don’t let anyone replace the logic board before you’ve decided about data.
