Why is the laptop hot during operation?

Perhaps it would not be an exaggeration to say that now laptops are becoming almost the main types of computers at home, replacing traditional stationary system units with monitors. Laptops have not only their undeniable advantages, but also the disadvantages, which can not be avoided anywhere.

One of the problems is repair. More precisely, it is much more difficult to repair a laptop, especially it is difficult to carry out repairs or diagnostics at home. More often than not, users are confronted with a high temperature problem and wonder why the laptop is hot ?

Causes of high temperature

During operation, laptops produce heat, the amount of which depends on the load. The processor, video card and other components spend energy to perform the tasks assigned to them. A side effect is high heat dissipation.

For the stable operation of a computer, powerful fans are required that can provide heat removal. So why is the laptop hot? Indeed, the presence of a powerful cooler is not yet a guarantee that the temperature will remain within normal limits.

However, there can be several reasons:

• The cooler has failed and does not support the required rotation speed.
• Inside the laptop, a lot of dust accumulated, making it difficult to move the air.
• High ambient temperature or closed air duct openings.
• Extremely high load and large heat generation for this cooler model.

These are the main reasons that explain why the laptop is warming up during operation. Consider the possibility of repair should be based on this.

Troubleshoot problems

The first reason is the failure of the cooler itself. It is a normal fan, which after a certain period of time will start to rattle, the loosened mechanisms will not cope with the load. Naturally, in this situation it is necessary either to replace the cooler or repair it.

However, if the cooler is OK and works properly at high speed, and the notebook warms up and turns off regardless of anything, or if it shows its problems somehow differently, the reason will be different.

The most common cause of why the laptop is warming up is the accumulation of dust. It is very difficult to fight against it, but it is necessary. The user must wipe the dust, blow all the cracks, vacuum the air ducts, then it will be possible to reduce the overall temperature during operation.

Dust degrades heat transfer, so the computer components begin to cool worse. So removing dust accumulations is really important for users.

Another common cause is the high temperature of the surrounding air. On a hot summer day, the temperature inside the laptop can rise significantly, so it's more difficult for fans to cope with cooling. So, wondering why the notebook is warming up, it would be advisable to check the conditions under which it is used.

In addition, very often with him working on the bed - blankets, pillows, mattresses perfectly keep the heat when we sleep, but they become disastrous for the computer. Sometimes we do not notice how a part of the blanket covered the main air holes. If this is the case, it is better to choose a more convenient place for work or arrange it so that nothing hinders. This will help special stands or computer tables.

Temperature measurement

Particular attention should be given to the method of determining the temperature. To carry out the diagnosis "by eye" is possible only if the temperature is really high, and the volume of the fan is significant.

To measure temperature, special applications that can determine the temperature of the processor and other components - EVEREST, Core Temp, MBProbe - will be useful. These utilities will help you determine what to do if the laptop is warming up, and most importantly, they will help to identify the problem in the early stages, preventing the burning of individual boards.
