What happens if water falls on laptop keyboard?

If water falls on a laptop keyboard, it can cause serious damage to the electronics inside the laptop. The extent of the damage will depend on factors like how much water spilled, what type of liquid it was, how quickly it was cleaned up, and the design of the specific laptop model. In most cases, it’s best to turn off and unplug the laptop immediately, dry it thoroughly, and then take steps like removing the keyboard to clean and dry internal components. With quick action, some water spills can be recovered from, but delays or powered-on states during the spill can lead to short circuits and corrosion that require expensive repairs or total replacement of the laptop.

Can a small water spill damage a laptop?

Yes, even a relatively small amount of water spilled on a laptop keyboard can potentially damage the device. Some key factors that determine the extent of damage include:

  • Amount of liquid – More water means more opportunities for shorts and corrosion.
  • Type of liquid – Water is least conductive, while soda, juice, coffee, etc are more risky.
  • Power state – Powered off is best, powered on risks shorts and frying components.
  • Speed of response – Quickly turning off power and drying reduces damage.
  • Laptop design – Some models drain liquid out, others trap it near electronics.

In general, liquid plus laptop internals is never a good mix. Even a couple tablespoons of water in the wrong place at the wrong time can fry a laptop’s logic board and other electronics. Immediate action is required to prevent serious damage after any significant liquid spill.

What are the immediate steps if water spills on a laptop?

If you accidentally spill water or another liquid on your laptop, quick reaction can be the difference between saving your laptop or permanently damaging it. Here are some immediate steps to take:

  1. Power off the laptop immediately – This prevents shorts and further damage.
  2. Unplug all cables/chargers – Removes power source and disables battery.
  3. Dry the exterior – Soak up water from keyboard, touchpad, vents with towel.
  4. Drain the laptop – Turn device upside down to let liquid drain out.
  5. Disassemble laptop – Remove keyboard, battery, bottom cover, and RAM to dry interior.
  6. Let dry for at least 24-48 hrs – Ensure no moisture left internally before reassembling.

The quicker you can power down, dry out the laptop, and remove power sources, the better chance you have of letting it fully dry out before permanent water damage occurs.

What are the risks if you keep using a wet laptop?

Continuing to use a laptop that has gotten wet can compound the water damage and make problems worse. Some specific risks include:

  • Short circuits – Moisture can create shorts between electronics.
  • Corrosion – Water conducts electricity that can corrode components.
  • Conductive buildup – Minerals in water create conductive paths.
  • Fried logic boards – Power shorts permanently destroy processors.
  • Stuck keys – Water under keys can jam the keyboard.
  • Spreading moisture – Heat from use spreads liquid to more parts.

Many times the initial spill does not immediately destroy a laptop, but using it while wet causes gradual shorts and corrosion that eventually catastrophic damage. Letting the laptop fully dry out first provides the best chance for recovery after a spill.

Can rice help dry out a wet laptop?

Placing a wet laptop in uncooked rice is a common attempt to help absorb moisture, but it has limitations:

  • Rice only absorbs surface moisture through the vents.
  • It does not remove moisture trapped internally under keys or inside the case.
  • Rice particles can get stuck and cause additional issues if they get inside the laptop.
  • Air drying or professional drying methods are more thorough and effective.

Overall, letting the laptop air dry open and disassembled is preferable to using rice. Rice may help marginally but does not solve the root problem or speed up internal drying enough to warrant the risks.

Can a laptop work again after being soaked in water?

It is possible for a laptop to work again after being fully soaked in water, but proper drying is crucial. The steps include:

  1. Immediately powering off and disconnecting all power.
  2. Disassembling laptop to the board level to access all components.
  3. Thoroughly air drying for at least 48-72 hours.
  4. Inspecting and cleaning all components of residue before reassembly.
  5. Replacing any damaged or corroded parts.
  6. Testing and reinstalling software once reassembled.

With a fully soaked laptop, the likelihood of failure is high if powered on prematurely before complete drying. Components must be 100% dry internally and externally before attempting to run the laptop again.

What liquids cause the worst laptop water damage?

Some liquids that can cause particularly severe water damage include:

  • Soda – Highly conductive and acidic.
  • Juice – Also conductive and acidic.
  • Coffee, tea – Corrosive and staining.
  • Salt water – Highly conductive and corrosive.
  • Alcohol – Conductive and can short circuit.
  • Milk, yogurt drinks – Residue conducts electricity when dry.

Even clean water can cause shorts and corrosion. But sticky, sugary, acidic, or conductive liquids can more readily penetrate and destroy laptop components once inside.

How long does it take for water to dry out inside a laptop?

It typically takes 24-72 hours for all internal moisture to fully evaporate inside a laptop after a water spill. Key factors include:

  • Amount of liquid spilled – More takes longer to dry.
  • Entry points – Narrow openings keep moisture trapped inside.
  • Humidity – Wet climates slow evaporation.
  • Internal airflow – Stagnant air keeps moisture around.
  • Components affected – Dense parts like the motherboard retain moisture.
  • Heat – Some use heat to speed drying, but can spread damage.

Given these variables, allowing a couple days for thorough air drying is recommended. Attempting to power on prematurely risks short circuiting from residual moisture inside.

Does shutting down a laptop help prevent water damage?

Yes, immediately shutting down a laptop as soon as water is spilled on it can help minimize water damage. Specifically:

  • Powering off disconnects electronic components, preventing shorts.
  • No power means no electrochemical reactions to corrode parts.
  • Water won’t reach full internal parts of an unpowered system.
  • Airflow from fans won’t spread droplets while powered off.
  • Some laptops even have drain holes that open when unpowered.

Shutting down won’t stop water from reaching sensitive spots. But it can greatly reduce the damage and potential for component failures once water has entered the laptop.

Is it safe to turn on a laptop that got wet?

It is generally not safe to turn on a laptop that has gotten wet until it has thoroughly dried. Risks of turning on a wet laptop include:

  • Short circuiting due to moisture bridging gaps in the logic board.
  • Corrosion spreading on electronics from electrochemical reactions.
  • Further spreading of the liquid to components due to heat buildup.
  • Failed bootup from water reaching RAM, HDD/SSD, or other parts.
  • Permanent damage to processors or boards from shorts and power spikes.

It’s best to wait at least 24 hours after a spill to allow complete evaporation before applying power again. This avoids compounding liquid damage issues when the machine tries to boot wet.

How do you fix a laptop that won’t turn on after water damage?

For a laptop that fails to power on after water damage, basic troubleshooting tips include:

  1. Dry laptop for 48-72 hours if recently wet and not dried yet.
  2. Check battery, charger, and adapter to ensure getting power.
  3. Drain flea power by holding down power button for 30 secs.
  4. Remove and reseat RAM modules and connections.
  5. Try external monitor in case LCD was damaged.
  6. Visually inspect boards for corrosion and water residue.
  7. Replace any damaged parts like keyboard, RAM, or hard drive.

If failures persist after cleaning contacts and replacing damaged parts, main system boards may need professional repair or replacement.

Can a laptop recover from water damage over time?

It is possible for a water damaged laptop to slowly recover some functionality over time if dried properly. This happens because:

  • Corrosion from minor spills slowly gets less conductive.
  • Liquid residue continues evaporating if left powered off.
  • Shorts caused by water can resolve as moisture fully dissipates.
  • Failed components like RAM may function again once fully dry.

However, time cannot reverse major physical damage. Components destroyed by short circuiting or corrosion need replacement. Only drying the laptop thoroughly right after a spill and being patient may allow natural recovery.


Water falling on a laptop is always an emergency situation. Quick response by powering off the device, gently drying it, and allowing time for interior evaporation can prevent permanent damage in many cases. Neglecting a spill or improperly drying a laptop greatly raises the risks of component short circuiting, corrosion, and failure. With prompt action, many laptops can recover fully after getting splashed or dampened. In severe soakings, replacement of damaged parts may still be needed for full function.
