It's no secret that the laptop heats up during operation, like other devices. Any other electronics and household appliances behave in exactly the same way - everything that surrounds us in a house or apartment, when working, emits a certain amount of heat. But the peculiarity of netbooks and laptops is that this technique almost always heats up in the lower part of the case, because of which not only the hard drive, but also the battery that is in fast charging mode is exposed to thermal loads. Covering the sofa, a plastic backing, a blanket, or even several sheets of paper lead to heat accumulation, which can cause the laptop to overheat, which will negatively affect the life time of some parts of your device.
The main fighters with overheating in laptops are the cooling circuit (usually it consists of a radiator and heat pipes), a cooler (popularly referred to as a fan), thermal grease (serves to increase the heat transfer from the laptop) and ventilation holes in the device case. When these funds become insufficient or they cease to fulfill their function properly, the laptop is very hot and may even fail. To avoid this, you need to pay attention to a number of disturbing calls, the loudest of which are:
- "slowdowns" in games. That is how overheating of a laptop begins to manifest itself in almost half the cases.
- device freezes. A laptop or netbook stops responding to commands and resumes its work only after restarting the system.
- spontaneous shutdowns of the device. The last sign that it’s time to do something with the laptop, otherwise it may finally fail.
If the laptop (“Acer”, “Samsung” and “HP” is overheating, more precisely, the budget models of these manufacturers are more likely to overheat) with enviable regularity, then it is time to sound the alarm and look for the cause of this phenomenon. Otherwise, a device that similarly signals a problem may fail much earlier than you planned. Let's look at what in most cases causes a laptop to overheat.
Dust accumulation. Most often, overheating of a laptop occurs precisely for this reason. Almost every cooling system in laptops and netbooks uses air flows and blowing a radiator around them as an additional influx of cold. With this air, dust particles settling on the fins of a radiator, cooler and microcircuit get into the device through several air intake openings of the case. Over time, the dust layer inside the laptop increases so much that it significantly interferes with the cooling system and leads to the shutdown of the laptop. Experienced users recommend scheduled cleaning of the laptop from dust at least once every six months. Then overheating problems are unlikely to bother your device.
Using the device on soft surfaces or closing air intakes. Many users do not even suspect that, having settled down comfortably with their favorite laptop on the couch and placing the device on a blanket, they block the air access to all air intake openings of the lower and side parts of the laptop case. Hot air continues to circulate inside the device until it reaches a critical temperature and the laptop overheats. For the same reason, it is not recommended to use a laptop on tables covered with a tablecloth.
Drying thermal paste. Thermal grease is necessary to improve heat transfer by the microcircuit to the radiator. When it dries after a certain period of time, the heat transfer can drop sharply, and the device will begin to overheat. It is recommended to update it at least once a year or immediately after problems with cooling.
If your laptop has started to overheat and you cannot determine the problem at home, it is best to contact a specialized workshop where they will be able to establish and eliminate the cause of overheating.
