How To Fix A Laptop Keyboard That Overheats

Using your laptop for prolonged periods, especially for high-intensity tasks like gaming or video editing, can cause it to heat up significantly. This is particularly uncomfortable when the keyboard becomes too hot to touch comfortably. Understanding why this happens and how to mitigate it can enhance your computing experience and extend the lifespan of your device.

Understanding Why It Gets Hot

Heat Generation in Laptops

The heat you feel on your laptop’s keyboard primarily originates from the components located directly beneath it, such as the CPU, GPU, and the motherboard. When these components work hard, they generate heat, which is then transferred to the keyboard area.

Common Causes of Excessive Heat

  1. Intensive Applications: Running resource-heavy programs such as graphic design software, games, or multiple applications simultaneously.
  2. Poor Ventilation: Blocking air vents with objects or using the laptop on a cushioned surface can restrict airflow, causing the internal temperature to rise.
  3. Dust Accumulation: Over time, dust can clog the laptop’s cooling fans and vents, reducing their efficiency.
  4. Aging Thermal Paste: The thermal paste between the CPU and its heat sink degrades over time, reducing its ability to transfer heat efficiently.

Practical Solutions to Reduce Keyboard Heat

1. Improve Ventilation

  • Use on Hard Surfaces: Always place your laptop on a hard, flat surface. Specialized laptop stands or cooling pads with built-in fans can significantly enhance airflow and cooling.
  • Clean Air Vents Regularly: Use compressed air to blow out dust from the vents to keep the cooling system efficient.

2. Manage Your Applications

  • Close Unnecessary Programs: Running multiple programs simultaneously can strain your CPU and generate extra heat. Use the Task Manager on Windows or Activity Monitor on macOS to close unnecessary applications.
  • Adjust Power Settings: Opt for ‘Power Saver’ mode which reduces processing power and, consequently, heat generation.

3. Regular Maintenance

  • Clean Internally: Periodically open up your laptop to clean dust from the fans and internal components. This task may require professional assistance if you are not comfortable doing it yourself.
  • Replace Thermal Paste: Consider replacing the thermal paste if your laptop is several years old. This can help improve heat dissipation from the CPU to the heat sink.

4. Environmental Adjustments

  • Ambient Temperature: Work in a cool environment. High room temperatures can exacerbate the heating issue.
  • Avoid Direct Sunlight: Keep the laptop out of direct sunlight to prevent additional heat accumulation.

5. Upgrade Hardware

  • Consider an External Keyboard: If the laptop’s keyboard gets too hot for comfort, using an external keyboard can provide a temporary solution.
  • Upgrade Cooling System: Some laptops allow for the addition of an extra fan or an upgraded cooling system, which can be a worthwhile investment if heat is a consistent issue.


While it’s normal for laptops to generate heat, especially during heavy use, it shouldn’t interfere with your comfort or the device’s performance. By following the tips outlined above, you can help manage your laptop’s temperature and prevent the keyboard from becoming uncomfortably hot. Always consider professional help for more complex maintenance tasks to ensure the longevity and efficient performance of your laptop.
