A laptop that severely overheats causes damage to the internal components. Before this happens, the laptop should attempt to shut itself down. It’s normal for a laptop to run warm, even too warm to comfortably perch on your lap while you’re using it. If you smell smoke, a burning odour, the fans never run or the fan runs all the time, be careful to avoid ruining your laptop.
Keep your laptop out of direct sunlight or a hot car interior and if you take it to an outdoor job site, mind that you keep it out of weather extremes. Some basic precautions and an understanding of what happens to a laptop when it overheats makes it possible to avoid a disaster.
An overheated processor slows down and operates less efficiently. In a computer system that functions properly, the fans should activate when the processor begins to overheat. Turning off the computer and using compressed air to blow out any dust accumulated in the fans can help improve performance in dirty systems, but it’s essential to avoid adding any moisture to the computer’s internal parts!
Most laptop batteries have lithium-ion batteries that can be harmed by heat. Batteries operate by a chemical interaction between negatively charged anode ions and positively charged cathode ions. When the computer starts to heat up, it accelerates this process and makes the ions start moving more swiftly. The added heat and increased chemical reaction reduces the battery life and amount of time it stays charged. With prolonged exposure to high heat, the battery may even become unusable.
Motherboards provide the skeleton for your computer. All of the computer’s important components such as processor, memory and even the fans are all connected to the motherboard. Several wires and copper components transmit electricity throughout the computer. When the computer begins to overheat, the efficiency and output of the electrical current gets reduced.
Using a computer-monitoring application that shows wattage and temperature can demonstrate just how strong of an effect overheating can have on a computer’s performance. For this reason, business owners who run extensive productivity applications or video-editing software often install large cooling systems for their computers.
Preventing laptops from overheating should be a primary concern of businesses that rely on employee productivity. Using a laptop cooling pad can help reduce some of the heat from a laptop. However, laptop cooling pads only provide part of the solution since they may mask a more serious internal cooling problem. When possible, clean your laptops regularly and take them to a professional to clean off the fans if you don’t have the expertise to do it yourself. For more handy users, taking the laptop apart with the battery removed and cleaning the inside with a soft cloth often provides a noticeable decrease in overheating.
