The term "laptop" implies that a laptop should be perched on your legs while you use it. You are likely to find that your laptop produces too much heat, making it impossible to use in this fashion. Laptop heat is the result of high CPU usage and an inefficient or restricted cooling system. Resolve these issues to keep your laptop cool and extend the computer's life.
Select the "Power Saver" setting in the Windows power options. This setting optimizes the computer for best battery life, slightly reducing the performance of some components. Because a computer component produces more heat when it runs at a higher speed, this reduces the computer's heat output.
Keep your laptop clean. Over time, dust can clog the intake and exhaust vents, and stick to the blades of the fan. This increases friction and restricts airflow. Use a brush and a can of compressed air to clean a mildly dusty laptop. To clean an old and severely dusty machine, you may need to open the computer's case for a more thorough cleaning, or to replace the cooling fan.
Avoid blocking the air intake vent on the bottom of your laptop. If the laptop is unable to bring air through the bottom of the computer, it cannot adequately cool its internal components. This can lead to overheating. Use your laptop on a table, desk or laptop stand whenever possible.
Keep windows or tabs open with video elements to a minimum. Playing videos consumes CPU resources, making your computer work harder. It also prevents your laptop's processor from entering an idle state and cooling down.
