If your device is very hot, suddenly shuts down, hangs, makes noise, or is malfunctioning, it’s time to take action.
It is quite easy to know that the computer is suffering from overheating. The case is very hot, and the noise of the fans does not subside even at rest. In the most serious cases, the device may freeze or suddenly shut down and then not restart until it cools down.
You can determine the temperature of the processor and graphics card with the help of special utilities, although most often the symptoms are so clear that there is no need for additional diagnostic tools.
Let’s consider the likely causes of overheating with professional link.
1. You are not operating the laptop correctly
Most laptops have an active cooling system in which heat is removed by blowing air through the radiator. If you put the laptop on a soft bed or a plaid with a long pile, the ventilation holes on the case will be partially or completely blocked. This, in turn, will lead to poor air circulation and overheating.
The solution is simple: do not place the laptop on soft surfaces, not to move close to the wall and always make sure that there is space near the ventilation holes.
And if you really want to watch TV in bed, use a book or other solid object as a base, so that the computer is located on it, not on the blanket.
2. Performing resource-intensive tasks
The higher the load on your processor and graphics card, the more heat they generate. If you play games or use heavy programs like video editors for a long time, this too can cause overheating. Take breaks to let your laptop cool down. Also, don’t abuse games and applications designed for higher-performance systems than yours.
Be especially attentive to games and resource-intensive programs on sweltering summer days. The temperature inside the device depends on the environment, so try not to overload the laptop in the heat.
If you often work with video, graphics or like to play – think about buying a stand (ideally – cooling). It will not only improve air circulation, but also increase comfort. In summer you can additionally include a room fan.
3. A lot of dust has accumulated inside
Dust particles and pet hairs get into the cooling system along with the air. They deposit on the radiators, impairing heat dissipation, and over time they accumulate and almost completely block the ventilation holes. This leads to overheating and the cooler running at maximum speed even at light loads.
You can try to clean the heatsink with a brush through the ventilation holes or gently blow out with compressed air, but it is unlikely to completely remove the clog. It is better to disassemble the laptop and remove all accumulated dust with the help of a step-by-step guide.
But remember: improper disassembly and cleaning can damage your computer. If you are not confident in your abilities, do not take the risk and take . And keep in mind that opening the case will result in a loss of warranty.
4. The thermal paste has dried out
To increase heat dissipation, thermo-interface, a special viscous paste, is applied to the processor and graphics card chips. Over time it dries out and loses its properties, which again leads to overheating.
To replace the thermal paste you will have to completely disassemble your notebook. You will need to remove the back cover, remove the battery, RAM, drive, as well as the cooler and other components that will prevent to get to the heatsink. The task is not easy, so it is better to find a video for a specific laptop model and act according to our instructions.
The replacement itself is much easier: you only need to remove the remains of the old thermal paste, apply a thin layer of new thermal paste and return all the components in place. For convenience, this procedure is usually combined with dust cleaning, so as not to disassemble the laptop on purpose.
5. Broken cooling system
The main breakdown – fan failure. This usually happens in very neglected cases, when there is so much dust and lint inside that they block the rotation of the cooler blades. This is accompanied by an increase in temperature and the deathly silence of the fan, which ceases to make any sound.
To figure it out, unplug the laptop, turn it off and remove the cover. Then place the device on the table, turn it on and run a few programs or a game. Carefully lift the side in which the cooler is located and check whether its blades move. Repeat the test several times at 5-10 minute intervals. If the fan does not work at all or spins too slowly, it is better to take the device to a service center.
6. A hidden miner is installed
The cause of laptop overheating may also be the accidental installation of a mining program. Such software, as well as viruses, greatly loads the processor and video card, which in turn causes the system to slow down and high heat generation.
The presence of the miner will be indicated by a non-stop cooler and slowing down even when performing simple tasks like opening a page in the browser.
