By | November 6, 2023

The humble keyboard cover, a thin piece of material designed to protect your laptop’s keyboard from dust, spills, and debris, has become a popular accessory for many laptop users. These covers offer a range of benefits, from improved hygiene to screen protection, but there’s also a persistent debate regarding their impact on laptop performance, particularly when it comes to overheating. In this article, we will explore the pros and cons of using keyboard covers and address the question: Do they cause overheating?


The Purpose of Keyboard Covers

At first glance, the primary function of a keyboard cover seems clear – to shield your keyboard from potential damage. Dust, food crumbs, and liquid spills are common culprits that can infiltrate your keyboard, causing inconveniences and, sometimes, long-term damage. Keyboard covers offer a straightforward solution by creating a barrier between your keyboard and the elements.

Maintaining a clean keyboard is not just about aesthetics but also about hygiene. Bacteria and germs can thrive in the spaces between keys, making regular cleaning and protection essential. Keyboard covers are designed to prevent these nuisances from making your keyboard their home.


Does Keyboard Cover Cause Overheating?

The overheating debate surrounding keyboard covers has been a subject of much discussion among laptop users. Some claim that keyboard covers can lead to overheating, while others dismiss the notion as a myth. The truth lies somewhere in between.

The impact of a keyboard cover on overheating may depend on several factors. The design and thickness of the cover, the laptop model, and how well the cover fits all play a role. The thickness of the cover can obstruct airflow, which is crucial for cooling laptops. If the cover significantly hinders airflow, it can contribute to higher temperatures, potentially causing overheating.

On the other hand, thinner and better-fitted keyboard covers may have a negligible impact on overheating. Modern laptops are designed to handle a range of operating conditions, and a thin cover might not disrupt the cooling system significantly. However, it’s essential to choose a cover that fits well and doesn’t obstruct ventilation openings.


Screen Protection and Scratches

One of the most prominent advantages of keyboard covers is their role in preventing scratches and marks on the laptop screen. However, there’s a catch – certain materials used in keyboard covers can leave marks or scratches on the screen. To prevent such screen damage, users must carefully select the right cover material and practice good habits when using the laptop.

In many cases, the issue arises when users close the laptop with the cover in place. The cover’s material can transfer onto the screen, leaving unsightly marks. However, this can be mitigated by removing the cover before closing the laptop or cleaning the screen thoroughly.


Hygiene and Maintenance


Keyboard covers contribute significantly to maintaining a clean and hygienic keyboard. They serve as a protective shield, preventing food crumbs, spills, and other contaminants from slipping between the keys. For users who eat or drink while working, a keyboard cover can be a lifesaver, as it keeps the keyboard free from stains and debris.

However, keyboard covers themselves require maintenance. Over time, they can accumulate dust and debris, which may affect their effectiveness. Regular cleaning and maintenance of the keyboard cover can help ensure it continues to serve its purpose effectively.


Typing Experience

While keyboard covers excel at maintaining a clean keyboard, they may impact the typing experience. Some users find that the presence of a cover changes the tactile feel of the keys, making typing less comfortable. The amount of key travel and the responsiveness of the keys can be affected, leading to a less satisfying typing experience.

Ultimately, whether or not a keyboard cover affects the typing experience is a matter of personal preference. Some users are willing to trade a slightly altered typing feel for the benefits of screen protection and hygiene, while others may prefer to type directly on the laptop’s keys.


Compatibility with Laptop Models


The impact of keyboard covers on laptop performance can vary depending on the laptop model and its design. Thinner, better-fitted covers are less likely to obstruct airflow and cause overheating issues. However, some laptop designs are more susceptible to overheating with a cover in place.

It’s essential to research the compatibility of specific keyboard covers with your laptop model and its cooling system. High-quality covers are designed to minimize interference with ventilation, ensuring that your laptop operates within safe temperature ranges.



In conclusion, the use of keyboard covers comes with a set of pros and cons. While they offer valuable protection against dust, spills, and screen damage, there’s a debate regarding their impact on overheating. The extent of this impact varies based on factors such as the design of the cover, the laptop model, and the user’s specific needs.

To make an informed choice, users should consider their laptop’s design, the quality of the keyboard cover, and their personal preferences. Proper maintenance, selecting the right cover material, and using the cover judiciously can help users enjoy the benefits while minimizing any potential downsides.
