Water Damage Repair Terms

Liquid enters a laptop through the keyboard and spreads across the motherboard. Water alone is less damaging than coffee, juice, or soda — sugary and acidic liquids accelerate corrosion. The single most important action after a spill: power off immediately and do not turn the laptop back on. Powering on while wet causes short circuits.

The chemical degradation of metal contacts and traces on the motherboard caused by liquid exposure. Corrosion begins within hours and worsens over days. Green or white residue on the board indicates active corrosion. Corroded traces can cause intermittent faults that appear weeks after a spill, even if the laptop initially seemed fine.

A specialist machine that uses high-frequency sound waves in a cleaning solution to remove corrosion, residue, and contaminants from circuit boards at a microscopic level. Ultrasonic cleaning is the most thorough method of water damage remediation — far more effective than manual cleaning with isopropyl alcohol alone.

When liquid bridges two electrical contacts that should not be connected, creating an unintended current path. Short circuits can blow fuses, damage chips, or destroy the power circuit entirely. Powering on a wet laptop is the main cause of short circuit damage — the liquid itself often causes less damage than the act of powering on.

The reaction between metal components and oxygen accelerated by moisture. Oxidised connectors and contacts have increased resistance, causing intermittent faults. Unlike visible corrosion, oxidation can be invisible to the naked eye. Ultrasonic cleaning removes oxidation that isopropyl alcohol cannot reach.
