Laptops have undergone an incredible amount of development over the past couple of years. A steep increase in performance was facilitated by chips that are ever more densely packed with transistors. In parallel, the amount of processors was multiplied, the hardware was put into slimmer cases, and better graphics cards enabled bigger screens with higher resolutions. These developments, however, come at a cost: heat. The greatest threat for your laptop, except for your your coffee mug, is overheating. It can cause hardware failure and permanent damage. In this article I will introduce ways that you can prevent or fix an overheating laptop and thus improve the performance and the extend the lifespan of your laptop. A sure sign that your notebook gets too hot is when your fan always runs at maximum speed. You may also experience reduced performance because the CPU cuts back its clock speed to escape heat pressure. Moreover, the fail safe software may trigger a sudden shutdown to prevent hardware damage.

There are several hardware fixes that can cure overheating. The first and most important thing you need to do when your laptop is overheating, is to clean the fan/s that provide/s cooling to the CPU and graphics card.

Over time they build up layers of dust and dirt that slow them down and block flow of air. Consult your laptop’s manual or manufacturer to find out how you can open the laptop to access and clean these parts. Before you attempt to do any cleaning, however, follow these steps: Carefully clean the fan/s with a cotton swab dipped in a drop of alcohol. Make sure the alcohol has completely evaporated before you reconnect the laptop to the power. You can also use a vacuum cleaner to remove the dust and dirt that clocks up the fan/s. To prevent damage to the fan, do not let it revolve in the wrong direction. If you want to use canned air to clean the fan, arrest the fan by holding it down. Next, you can clean the exhaust port by sucking out air with a vacuum cleaner. The exhaust port usually sits on the side of the laptop. It’s the opening that blows out hot air. The intake grills are small openings that allow air to be sucked into the laptop by the revolving fans. They can sit on the sides or at the bottom of your notebook.

To clear the intake grills, spray them with canned air. Finally, you can apply fresh thermal grease to the interface between the CPU and its heat sink. Again, please consult the laptop’s manual or manufacturer to obtain instructions on how to disassemble these components. Inside My Laptop has some great tutorials on how to fix your laptop, including How to apply thermal grease on laptop processor. Most laptops suck in cooling air through their bottoms. If the laptop sits on an uneven surface like a blanket, pillow, or your lap, the flow of air into the laptop is disturbed. Subsequently, the cooling is not optimal, heat builds up, the surface becomes hot, the temperature of sucked in cooling air increases, and eventually the laptop overheats. This scenario is easily avoided by keeping the laptop on a hard and flat surface. You can use something as simple as a tray or get a special laptop holder or lap stand. Laptop coolers are meant to provide additional cooling.

However, getting the wrong cooler can actually make the problem worse. Before you purchase a cooler, you need to understand the flow of air into and out of your laptop. As mentioned above, most laptops suck in air for cooling from the bottom. This makes sense because warm air rises upwards. However, a cooler that sits underneath the laptop and sucks air away from it, does not contribute to laptop cooling and rather causes a more rapid overheating. If your laptop has intake grills at its bottom, purchase a cooler that blows cool air upwards, i.e. into the laptop. You can also get a passive cooler that does not consume power and merely absorbs heat. If none of the hardware fixes result in lasting improvements, you can also revert to software fixes that address the performance and power usage of your laptop. However, addressing excessive heat with a software fix means you give up performance in favor of preserving the hardware. You can either reduce the brightness of your screen or reduce the CPU clock speed.

In Windows, underclocking or undervolting is done in the BIOS, but can also be controlled through software tools. Consult the Undervolting Guide on the Notebook Review forum for more information about this procedure. Finally, let’s lighten this up a little. This list was inspired by a Top 11 list on BBSpot. How often do you clean your laptop to prevent it from overheating? Do you have any additional tips and tricks to share?

Check for BIOS updates and install them using instructions in the HP support document Updating the BIOS. Step 4: Using HP CoolSense technology HP CoolSense technology is a feature in some HP notebook (laptop) computers that combines hardware, software, and mechanical design to dynamically manage the temperature of your laptop computer. HP CoolSense uses a motion sensor in your laptop to sense when your laptop is being used in a stationary or mobile setting, and automatically adjusts the laptop performance and fan speed to keep the computer cool. You can set HP CoolSense software to your specifications. For more information, see HP Notebook PCs - HP CoolSense Technology.
