Water Damage: Laptop & Computer Emergency First Aid
GOAL: Prevent electrical shorts and corrosion damage
Power Off Immediately
Do NOT check if it still works — this can cause fatal short circuits. Hold the power button down until the device is completely powered off (usually 5-10 seconds). Every moment the device stays on increases corrosion risk.
Disconnect All Power and Peripherals
Immediately unplug the charger, power cable, and all connected devices including: USB drives, external hard drives, mouse, keyboard, and any other accessories. This prevents electrical pathways from conducting water to sensitive components.
Remove the Battery (If Possible)
If your laptop has a removable battery, take it out immediately. This completely cuts power to the motherboard and is the most effective way to prevent short circuits. For MacBooks and ultrabooks with sealed batteries, skip to step 4.
Drain and Position for Drying
- Laptops: Open the lid to approximately 90 degrees and place the laptop keyboard-side down on a dry, absorbent towel. This allows liquid to drain away from the motherboard.
- Smartphones/Tablets: Gently dab with a lint-free or microfibre cloth. Avoid shaking the device as this spreads liquid further inside.
- Desktop PCs: If liquid entered the tower, place it on its side with the access panel facing down.
What NOT to Do After Water Damage
- Do NOT use rice — Rice dust and starch can penetrate ports and cause corrosion. It's also ineffective at removing moisture from internal components.
- Do NOT use heat — Hairdryers, ovens, and microwaves warp components and melt adhesives. Heat also forces moisture deeper into the device.
- Do NOT shake — Shaking spreads liquid to previously dry areas and can cause shorts.
- Do NOT power on — Wait until professionally cleaned. Even if it appears dry, invisible moisture can cause failure days or weeks later.
