As users become more and more laptops. During operation there are problems with overheating of the computer. This is reflected in the spontaneous departure laptop to sleep, in some cases, emergency stop. There is a significant slowing of your computer, this is due to the operating system attempt to reduce the load on the CPU by reducing the number of calculations, to reduce power consumption, the programs that previously loaded in 15-20 seconds loaded for 1-2 minutes. After downloading run slowly.

There are two variants of overheating:






Lost its properties thermal paste on the processor

  • Overheating processor due to loss of heat conduction properties of the radiator, in this case, it loses its properties thermal compound which transfers heat to the heat sink from the processor.

Identify a fault just need to removing the rear cover to check the temperature of a heat sink. If it is cold, but the laptop is turned off periodically, so broken heat transfer from the processor. This failure happens, but rarely, and usually due to poor-quality thermal paste. High-quality thermal grease is designed to operate in high temperatures and retains its properties (not dry) 6-10 years. Since notebook manufacturers are not advantageous to use a bad paste (treatment during the warranty center during the guarantee many times exceed the cost of high-quality paste) used in laptops quality thermal grease designed for a lifespan of about 10 years.

  Overheating processor due to insufficient cooling.

In this case, you must pay attention to the heating of the notebook.

If the body is heated strongly, if the fan is running, check, remove the back cover and look at the fan, whether it rotates. When rotated, then everything is fine with him, then you need to remove the fan, he secured several bolted to the body. Generally dust clogged radiator cell, because of this hot air not comes out from the laptop.

Here is the dust clogged heatsink on a real laptop.

The cooling fan that blows air out of the notebook.

cooling radiator that is at the end of heat-pipe, heat is transferred to the radiator, fan banishing air through the radiator cell cools the processor.
