Liquid Spills on Laptop

I have repaired many Laptops exposed to accidental liquid spills. This is a recoverable condition in most cases. It is most important to respond to the cleaning up process as soon as possible (before corrosion or internal soakage occur)! Liquid intrusion can cause the following types of laptop damage:

• Short circuit due to conductive nature of wet liquid (problem may clear as liquid dries)
• Short circuit due to dried liquid residue
• Corrosion occurs (particularly volatile with some acidic soft drinks — Coke)
• Electronic components damaged by above short circuits

Possible Solution: Immediately when a spill occurs, turn off the laptop, invert the laptop and leave the unit upside down (drainage) for at least 20–30 minutes. Then, remove any attached leads, remove the power unit and battery, and allow the unit to air-dry overnight.

To remove any liquid residual: Have someone remove the keyboard assembly and perform additional cleaning. It may help to use cotton buds and distilled water to remove any contamination. Where corrosive side effects may be suspected (with coke), gently rub any suspect areas with a cotton bud dampened with CRC or WD-40. Dry the treated areas so that only a light film of the WD-40 anti-corrosive solution remains. While the keyboard is removed, use a bright light and magnifying lens to inspect areas where the liquid made contact.
