Understanding the Risks of Using Water

Water and electronics are a notoriously bad mix. Laptops are intricate machines with sensitive internal components. Introducing water, even in small amounts, can lead to serious problems.

Electrical Short Circuits

Water is a conductor of electricity. When water comes into contact with the internal circuitry of your laptop, it can create short circuits. These shorts can damage components beyond repair, rendering your laptop useless. Even if the laptop is turned off, residual power in capacitors and other components can still cause damage in the presence of water.

Corrosion

Over time, water can cause corrosion on the metal parts inside your laptop. This corrosion can lead to component failure, reduced performance, and ultimately, a shorter lifespan for your device. The minerals in tap water further accelerate the corrosion process. Even distilled water, while less conductive, can still contribute to corrosion over the long term.

Sticker Damage and Key Malfunction

The stickers on your keycaps, with their letters and symbols, are vulnerable to water damage. They can peel off, fade, or become discolored. Moreover, water can seep underneath the keycaps, causing them to stick or become unresponsive. This can severely hinder your typing experience and necessitate costly repairs.
