What if I spill water on my MacBook Pro?

Spilling water or any other liquid on your MacBook Pro can be a scary situation. Your expensive laptop is suddenly at risk of serious damage if you don’t act quickly. Thankfully, there are steps you can take right away to give your MacBook the best chance of survival.

What to do immediately after a spill

If you’ve just spilled water or another liquid like coffee, soda, etc. on your MacBook Pro, follow these steps immediately:

  1. Unplug the laptop if it’s connected to a power source.
  2. Turn the laptop off by pressing and holding the power button for 5-10 seconds.
  3. Disconnect any peripherals like external drives, chargers, hubs, or cables.
  4. Gently shake the laptop to drain out as much liquid as possible from ports, vents, and openings.
  5. Quickly wipe away any pooled liquid on the keyboard, trackpad, and exterior with a clean towel or tissue.
  6. If possible, place the laptop keyboard-side down on the towel to help drain out liquid and prevent further spreading.

Getting the laptop powered off and draining away exterior liquid right away can prevent short circuits and fires. Avoid wiping the screen, as that can damage the display coating.

Assessing the spill damage

Once you’ve done the immediate steps above, assess the situation:

  • What liquid was spilled? Water? Coffee? Soda?
  • How much liquid was spilled? A few drops or a whole cup?
  • Which areas of the laptop got wet? Just the keyboard or other parts too?
  • Is there any visible damage already? Cracked case, malfunctioning keys, etc.
  • Are there any unusual smells coming from the laptop?

Ideally, it was a small amount of water, limited to the keyboard and palm rests. Larger spills reaching the trackpad, ports or display are more concerning. Spilling sugary or acidic drinks can also lead to quicker corrosion.

Dry out the laptop

Once you’ve done the quick cleanup, the next goal is to thoroughly dry out the laptop. Water and moisture trapped inside can short circuit components and lead to corrosion over time. Here are some dos and don’ts:

  • DO let the laptop dry out for at least 24-48 hours before turning it on again. This gives time for any residual moisture to evaporate.
  • DO keep the laptop on an inclined surface so the liquid can drain out. Place it keyboard-side down at a 45 degree angle.
  • DO use dry towels, tissues, or paper towels to absorb moisture from the keyboard, ports, vents, etc.
  • DO leave the laptop in a dry, warm area to speed up drying. Near a fan or dehumidifier is best.
  • DO consider carefully disassembling the laptop if you’re comfortable doing so in order to clean and dry the inner components.
  • DON’T try to dry the laptop using an external heat source like a hairdryer, which can damage the internal components.
  • DON’T turn the laptop on or plug it in until you’re sure it’s 100% dry.
  • DON’T close the laptop or position it in a way that traps moisture inside.
  • DON’T use rice to try to absorb moisture, as rice dust can get inside and gunk up components.

Cleaning up and drying out the internals

If you have experience taking electronics apart, consider carefully disassembling your MacBook to clean up and dry out the insides. This allows you to remove any residual moisture and assess any internal damage. Here are some tips if you go this route:

  • Completely power down the laptop and disconnect the battery before disassembling.
  • Use an iFixit guide for your specific model to disassemble correctly.
  • Thoroughly clean the logic board, connectors, fans, ports, etc. using 90% isopropyl alcohol and soft brush.
  • Gently shake out trapped moisture from crevices and openings.
  • Let the bare logic board and internal parts dry out for 24-48 hours before reassembling.
  • Inspect components like the logic board, keyboard, trackpad, battery connectors, etc. for corrosion or damage.
  • Consider replacing damaged components like the keyboard or battery if needed.

Note that opening up your laptop and disassembling voids the warranty. So only attempt this if you’re experienced working on electronics.

Reassemble and test out the laptop

Once everything is fully dry:

  1. Carefully reassemble the laptop by following the disassembly steps in reverse.
  2. Reconnect the battery and any other cables or connectors.
  3. Before turning it on, inspect for any debris, damaged screws/clips, or loose connections.
  4. Power on the laptop and test basic functionality like keyboard, trackpad, screen, ports, etc.
  5. If it works, backup any data ASAP in case of issues down the line.
  6. Use for a short period to verify it’s working properly and nothing delayed pops up.
  7. Consider getting a professional to inspect and validate everything is OK if you can.

Hopefully at this point your MacBook survives the spill intact. But issues could show up later, so continue monitoring it closely.

Potential issues after liquid spills

Even if your laptop seems to be working fine initially after a spill, problems can show up over time. Here are some common issues to keep an eye out for:

  • Corroded connections: Liquid can corrode metallic contacts and connectors, leading to flaky connections or component failure over time.
  • Short circuits: Residue from the liquid can create short circuits between components, especially on the logic board.
  • Component rust: Any exposed metallic parts like screws can rust with enough moisture.
  • Damaged circuits: Sensitive components on the logic board can malfunction or fail if exposed to moisture.
  • Battery issues: Liquid getting into the battery compartment can short circuit the battery cells.
  • Keyboard/trackpad failure: These intricate components can easily malfunction if liquid seeps underneath.
  • Fan issues: Fans can get obstructed by dust and particles in liquid residue.

If you start noticing any of these problems, it’s best to get professional help assessing the damage and fixing the faulty components before it gets worse.

When to get professional help

Here are some signs you should stop trying to troubleshoot on your own and get professional assistance:

  • You spilled a large amount of liquid, beyond just the keyboard/trackpad area.
  • There are visible signs of external damage like cracks in the case.
  • The laptop won’t turn on at all, even after drying out for over 48 hours.
  • It powers on but is clearly malfunctioning, like display distortions or no keyboard/trackpad response.
  • You notice corrosion, damaged ports, non-working components, etc. when inspecting the internals.
  • Problems start occurring like random shut downs, battery issues, corrupted data, etc.

For any of these situations, take the laptop to an Apple repair center or trusted third-party Mac repair shop. They have the expertise and tools to accurately diagnose any liquid-related damage and fix it professionally.

DIY MacBook spill damage repair tips
