Step 1: Power off immediately — don't save your work first

This is the hardest instinct to fight. Your first thought will be to save your open documents. Don't. Every second the laptop is powered on while wet is a second that electricity is running through circuits that are now conducting in ways they weren't designed to. Hold the power button until it shuts off. Do it now.

Do not put it to sleep. Do not close the lid. Do not "just finish this one thing." A hard power off is the only safe option.

Step 2: Unplug everything

Charger out. USB devices out. Any docking station disconnected. If liquid is actively draining toward any port, tilt the laptop gently to redirect it away from the board — but don't shake it aggressively, which spreads liquid further inside.

Step 3: Remove the battery if you can

Older laptops with removable batteries — take it out now. This cuts the primary power source to the board even if residual charge remains in capacitors. Most modern ultrabooks (MacBooks, recent ThinkPads, Dell XPS) have internal batteries that require disassembly to remove. If that's you, move to step 4.

Step 4: Open the lid fully and flip it

Open the laptop to approximately 90 degrees and place it face-down on a dry towel, forming an inverted "V" shape. This lets gravity pull liquid out through the keyboard rather than further into the chassis toward the motherboard. Leave it like this for at least 30 minutes.

Step 5: Blot — don't wipe, don't blow

Use a lint-free cloth or paper towel to gently blot visible moisture from the keyboard, ports, and chassis. Do not wipe — wiping spreads liquid. Do not use a hair dryer — heat can warp plastic, shrink seals, and push moisture deeper. Do not blow into ports with your mouth — breath contains moisture.

The "put it in rice" advice is largely a myth. Rice doesn't absorb moisture effectively from sealed electronics, and rice dust can get into ports and cause its own problems. Skip it.

Step 6: Do not try to turn it on to 'test it'

Even if the laptop looks dry and feels dry after an hour, internal moisture can remain — especially under chips, between board layers, and inside connectors. Powering on a wet board causes short circuits that permanently damage components that would otherwise have survived. The temptation is real, but resist it.

What liquid was it?

The type of liquid matters significantly for recovery odds. Pure water is the least damaging — it doesn't leave conductive residue once dried. Coffee, juice, soft drinks, and beer are far worse because they leave sugary, acidic residue that corrodes traces and pads even after the liquid itself has evaporated. Salt water (sea water, sweat) is aggressive and acts fast.

  • Pure water — 70–80% recovery with prompt action
  • Coffee or tea (black) — 50–65% recovery
  • Coffee with milk/sugar, juice, soda — 35–50% recovery
  • Beer or wine — 30–45% recovery
  • Salt water or sea water — 20–35% recovery, act very fast

What we do when it comes in

We fully disassemble the laptop, inspect the board under magnification, and run it through an ultrasonic cleaner with isopropyl alcohol solution to dislodge mineral deposits that air-drying leaves behind. We then dry it thoroughly, inspect every connector, and test on a bench power supply with a current limit — so if a short remains, we catch it before it causes further damage.

Time since exposure is the biggest factor in outcome. The sooner you bring it in, the better your chances.

The longer you wait, the more corrosion sets in.
