Assess the Spill Situation
The first step after a liquid spill on your MacBook is to quickly assess the situation. Determine what type of liquid was spilled and approximately how much made contact with your computer. Even small amounts of water or other liquids can potentially damage internal components.
Carefully inspect where on the MacBook the liquid spilled. Did it mostly hit the keyboard and trackpad, or did some drip down below the screen or onto the bottom or sides? Pay attention to where the liquid seemed to pool or seep into cracks. This will give you an idea of what internal parts could be affected.
Try turning on your MacBook if it was off when the spill occurred. Check if it successfully boots up and seems to function normally. See if the keyboard and trackpad still work properly and respond as expected. Any issues turning on the computer or with its functionality could indicate liquid damage.
It’s important to quickly gauge the nature of the spill, as the longer liquid sits inside a MacBook, the more likely it is to cause permanent damage. This initial assessment will guide your next steps in addressing the issue.
Immediate First Steps
If you’ve accidentally spilled water or another liquid onto your MacBook, it’s important to take immediate action to try to mitigate any damage. The first things you should do are:
- Unplug all cables and turn off the MacBook. This helps prevent any electrical shorts that could fry components.
- Wipe off any excess liquid with a dry, absorbent towel or cloth. Be gentle and don’t rub too hard.
- Flip over the MacBook and open it up to drain out any collected liquid through openings and vents. Gravity will help the liquid drain out.
Acting quickly can make a big difference in saving your MacBook from permanent water damage. Just be sure not to turn it back on until you’re certain it’s fully dried out, which could take 1-3 days. Leaving it off prevents shorts and gives time for any lingering moisture to evaporate.
Inspect for Damage
After an initial drying, inspect your MacBook carefully for any signs of water damage. Check for visible water marks or corrosion on the external aluminum case, which could indicate liquid penetration (1). Also examine the ports and connectors for any discoloration or tarnished pins.
To thoroughly inspect for internal damage, you may need to open the MacBook casing. This will allow you to look for any traces of moisture on internal components like the logic board, battery, trackpad, keyboard, and fans (2). Water could short circuit or corrode delicate electronics. Check under keyboard keys and the trackpad as well. If you find signs of water inside, you’ll likely need professional repair.
Be very gentle when opening the casing, following guides for your specific MacBook model (3). Make sure to unplug the battery before proceeding. Look for any white corroded areas or moisture beads on the logic board that could indicate damage.

Dry Out the MacBook
The most important step after a water spill is to thoroughly dry out all components before turning your MacBook back on. Water can quickly cause corrosion and electrical shorts, so you want to remove any trace of moisture.
Start by disassembling the MacBook further to fully expose internal components to air. Remove the bottom case, battery, logic board, heat sink, fan, speakers, trackpad, and any other parts you can safely detach. Lay the parts out separately on a towel.
Allow everything to sit undisturbed for 24-48 hours to give sufficient time for moisture to fully evaporate. Position near a fan or dehumidifier to speed up drying. Do not use an external heat source like a hairdryer which can damage electronics.
Check carefully for any remaining damp areas before reassembling. Look for moisture trapped under chip surfaces and connectors. If needed, let sit longer until completely dry.1
Once satisfied everything is dry, carefully reassemble the MacBook and test functionality before powering back on. With luck, you were able to dry it fast enough to avoid permanent water damage.
Replace Damaged Parts
Water damage can cause corrosion and damage to internal MacBook parts like the logic board, trackpad, keyboard, speakers, ports, and battery. If parts have visible corrosion, mineral deposits, or are not functioning properly, they will likely need to be replaced.
Two of the most commonly damaged parts that may need replacing after water exposure are the logic board and battery. The logic board contains the processors, RAM, and other key components that allow the computer to function. If the logic board is corroded or shorted out, the MacBook will not power on. Replacing the logic board can be an expensive repair, often over $500 for parts and labor.
The battery can also be damaged by water exposure. Liquid can short circuit the battery cells or cause corrosion of the connectors. A bulging or leaking battery should be immediately replaced. Swapping in a new Apple genuine battery will typically cost $100-200.
Other parts that may need replacement include the trackpad, keyboard, speakers, ports, and display assembly. Any part that has visible water damage or is malfunctioning likely needs to be swapped out. Parts can be sourced from Apple, third party suppliers, or salvaged from donor boards.
When installing new parts, it’s important to thoroughly clean the connectors with isopropyl alcohol to remove any residual minerals left by evaporating water. This helps ensure a good connection between parts.
Test Functionality
After drying out the MacBook, the next step is to reassemble it and attempt to power it on. Carefully put all components back in place, being mindful of any cables or connectors that may have been loosened or dislodged.
Once fully reassembled, press the power button and see if the MacBook turns on. If it powers up successfully, that’s a good sign there may not be extensive damage. Thoroughly test all components and functions:
- Check that the keyboard, trackpad, ports, speakers, screen, webcam, and any other parts are working properly. Try keys, gestures, plugging in devices, adjusting audio, and running apps that utilize various components.
- Examine the screen for any dead, discolored, or flickering pixels which could indicate water reached the display.
- Test all ports with external keyboards, mice, drives, and monitors to see if the connectors have been affected.
- Try out features like the camera and microphone to ensure full functionality wasn’t compromised.
Meticulously inspecting everything after a spill can help pinpoint any specific issues or parts that got damaged. Full operation indicates the water likely did not reach or corrode internal electronics and components.
Check for Lingering Issues
Even if your MacBook seems to be working normally again after drying out, it’s important to monitor it carefully for signs of lingering liquid damage in the days and weeks after the spill. Water can cause corrosion over time, and problems may not appear right away. Keep an eye out for odd behavior like random crashing or freezing, overheating, strange noises from the fan, issues charging, glitches on the screen, or keyboard keys not working properly. These can all indicate water caused internal damage that is now manifesting.
Small amounts of moisture can get trapped internally and lead to oxidation or short circuits. So continue to use your MacBook cautiously and back up data regularly just in case. If you notice new problems arising that worsen over time, it likely means lingering liquid damage is still present internally. You may need to have a repair shop open it up to assess and fix any corrosion.
Overall, don’t assume your MacBook is good to go just because it boots up normally again. Monitor it vigilantly for at least a few weeks post-spill to ensure no delayed problems start appearing.
Data Backup Options
If the MacBook is still functioning after the spill, it is crucial to immediately back up your data before any liquid damage can worsen and result in drive failure. Copy important files and folders to an external hard drive or cloud storage service like iCloud or Dropbox to safeguard your data (source). The sooner you can backup, the more data you will likely be able to recover.
If the hard drive stops functioning due to liquid damage, professional data recovery services may be able to recover lost data, but this can be an expensive process. Companies like DriveSavers and Gillware specialize in hard drive recovery and have advanced tools and techniques for extracting data from water damaged drives (source). However, the longer a water damaged drive goes without proper repair, the lower the chances of recovering all lost data. So seeking professional help quickly is key.
When to Seek Repair
If your MacBook exhibits certain symptoms after a spill, it’s a sign professional repair or cleaning may be needed. These include:
- Visible internal damage seen during inspection, such as corroded connectors or frayed cables
- The MacBook failing to power on or not charging
- Display issues like flickering, distortion, or dead/black pixels
- Keyboard or trackpad failing to respond
- Speakers or headphone jack malfunctioning
- Any error messages, crashes, or other abnormal system behavior
Liquid damage repairs for MacBooks tend to range from $300-$600 or more, depending on your model and the extent of the damage. For example, one estimate for a 2017 MacBook Air was around $500-$600. Some Reddit users reported costs of $300 for water damage board replacement from Apple. Independent repair shops may charge $200-300. The sooner you can get an assessment, the better chances of minimizing damage and cost.
