Sharing is Caring

Have you ever dropped your laptop into water or spilt a drink? If it describes you, know that you’re not alone. Laptops often break down because of water damage, which can be repaired or possibly require replacement at great expense. Why, then, aren’t laptops designed to withstand water damage? Waterproof laptops may seem like a straightforward answer to a widespread issue, but several roadblocks still need to be addressed.

Laptops are intricate technological devices with various ports and openings for speakers, microphones, and cooling fans. A fully sealed enclosure would have to be constructed to keep water out of the gadget, which is challenging given the number of holes in the design. Silicone and other waterproofing elements can increase a laptop’s weight and size, making it less convenient to carry around and less tempting to potential buyers.

Water-resistant features, such as spill-resistant keyboards or coatings that repel water, are making their way into particular laptops despite these obstacles. This article will help you understand the physics behind making laptops watertight and why this is more difficult than it sounds.

The Science Behind Water Damage to Laptops


A laptop’s motherboard, hard drive, keyboard, screen, and battery are essential. Any or all of these parts may be harmed by water damage, rendering the laptop useless. Depending on how much water enters the laptop and how soon it is evacuated, the damage caused by water can range from minor to severe.

A laptop may experience short circuits and other forms of damage since water is an excellent electrical conductor. Water can make a conduit for electricity to flow where it shouldn’t matter when it touches an electrical component. This may result in a short circuit, permanently damaging the part or even a fire.

Various liquids have different effects on laptops. For instance, water may be easily removed from a laptop, and the harm it causes can be reduced if the laptop is shut off right once, dried off, and professionally cleaned. Conversely, beverages like coffee, soda, and other sweet drinks can harm a laptop far more. These liquids may leave behind sugars and residue that can corrode parts and result in more severe harm.

Reasons Why Aren’t Laptops Waterproof?

The difficulties in shielding its internal components from water damage are one of the main reasons laptops aren’t waterproof. For optimum performance, laptops need access to several ports and vents, which can be challenging to block off entirely. Also, while in operation, laptops produce heat, and the cooling system controls temperature using the same vents and fans. By isolating these parts, the laptop risked overheating and eventual damage.

Making laptops waterproof presents additional challenges in terms of cost and design trade-offs. Making a laptop waterproof would probably call for more materials and manufacturing techniques, which could raise the cost of manufacturing. Also, waterproof laptops may weigh more and be thicker than their non-waterproof equivalents, affecting their portable and functional properties.

Moreover, waterproofing a laptop would reduce battery life since maintaining waterproofing elements like connectors, seals, or special coatings would consume more energy. Finding a balance between battery life and waterproofing characteristics without losing functionality or portability may be difficult.

Having a waterproof laptop is an appealing concept, but it is challenging. It isn’t easy to create a waterproof laptop without reducing performance or usability due to the requirement for access to ports and vents, cost considerations, and design choices. To lessen the effects of water damage, manufacturers have begun to add some level of water resistance in some laptops, such as employing water-repellent coatings, sealing vulnerable ports, and providing drainage channels.
