If your laptop seems to get really hot or shuts down unexpectedly, it may need a thorough internal cleaning. If your laptop is overheating, it can cause serious damage. Fans are installed to pull air into and out of the laptop case to remove heat. With the continued pushing and pulling of air, dirt and dust moves into our laptops (and not always out of our laptops). Because of its compact nature, over time, dust and dirt accumulates inside the laptop clogging the components designed to facilitate heat removal. When dust accumulates around the processor, it begins to overheat because it is not being cooled properly.
