Are Keyboard Covers Bad For Laptops

When it comes to laptop maintenance, it’s crucial to separate fact from fiction. Keyboard covers have gained popularity as a preventive measure against liquid spills, crumbs, and dust infiltration. However, some critics argue that these covers can trap heat, leading to potential overheating issues. In this article, I’ll examine the validity of these claims and explore whether keyboard covers are truly detrimental to the overall performance and longevity of your laptop. Stay tuned for a comprehensive breakdown of the pros and cons of using keyboard covers for laptops.

What Are Keyboard Covers?

Keyboard covers are protective accessories designed to shield the keyboard of a laptop from spills, dust, and other external elements. They are typically made of silicone or other flexible materials that conform to the shape of the keyboard. Users can easily fit the cover over the keys, creating a barrier between the keyboard and potential hazards.

Keyboard covers offer several benefits, including:

  • Protection against spills: Accidents happen, and liquid spills can cause significant damage to a laptop’s keyboard. A keyboard cover acts as a waterproof layer, preventing liquids from seeping into the keys and potentially damaging the internal components.
  • Defense against dust and debris: Dust and debris can accumulate between the keys, affecting their performance and causing keys to stick or become unresponsive. A keyboard cover helps to keep out dust and debris, preserving the lifespan and functionality of the keyboard.
  • Easy maintenance: Keyboard covers are easy to clean and maintain. They can be removed, washed with mild soap and water, and dried before putting them back on. This makes it effortless to keep the keyboard clean and hygienic.

Pros of Using Keyboard Covers

Protection Against Dust And Debris

One of the main advantages of using a keyboard cover for your laptop is the added protection it provides against dust and debris. As we use our laptops daily, dust particles and other small particles can easily accumulate in the spaces between the keys. Over time, this buildup can interfere with the performance of your keyboard, causing keys to stick or not register properly.

By using a keyboard cover, you can prevent dust and debris from entering the keyboard and affecting its functionality. The cover acts as a barrier, keeping unwanted particles out and ensuring that your keys remain clean and in good working condition. This can significantly extend the lifespan of your laptop’s keyboard and save you the hassle and expense of having to get it repaired or replaced.


Spills are an unfortunate reality of life, especially when working or enjoying a meal near your laptop. Accidental spills can have disastrous consequences for your laptop’s keyboard, potentially rendering it useless and resulting in costly repairs.

This is where a keyboard cover can come to the rescue. Many keyboard covers are designed to be waterproof, providing an added layer of protection against liquid damage. Whether it’s a cup of coffee, a glass of water, or any other liquid, a keyboard cover can act as a barrier, preventing the liquid from reaching your laptop’s keyboard. This can give you enough time to react, quickly wipe away the spill, and minimize the chances of any permanent damage.

With a waterproof keyboard cover, you can use your laptop with peace of mind, knowing that accidental spills won’t ruin your day or your device.

Cons of Using Keyboard Covers

Potential Heat Buildup

Another consideration when using keyboard covers is the potential for heat buildup. Laptops generate heat during operation, and efficient heat dissipation is crucial for maintaining optimal performance and preventing damage to internal components. While most laptops have built-in ventilation systems, using a keyboard cover can impede proper airflow and contribute to heat buildup.

Heat buildup can lead to overheating, which can result in system slowdowns, crashes, and even permanent damage to internal components. By obstructing the ventilation holes or blocking the airflow between the keys, a keyboard cover may limit the laptop’s ability to cool down effectively.

Interference With Special Keyboard Features

Keyboard covers may also interfere with special features or shortcuts that are specific to a laptop model. For example, some laptops have backlit keyboards that allow users to type in low-light conditions. The presence of a keyboard cover can block the light from reaching the keys, rendering this feature ineffective.

In addition, some keyboards have touchscreen capabilities or advanced trackpads with gesture support. Keyboard covers may limit the sensitivity or accuracy of these features, affecting their overall usability.


In evaluating the use of keyboard covers for laptops, it becomes clear that while they provide valuable protection against dust, debris, and spills, there are potential drawbacks to consider. The reduction in tactile feedback and interference with special keyboard features may impact the overall user experience. Additionally, the risk of heat buildup and hindered ventilation can lead to overheating and damage to internal components.

The use of keyboard covers for laptops is a personal choice that should consider both the benefits and potential drawbacks. By making an informed decision, users can ensure the longevity and usability of their laptops while maintaining their desired typing experience.
