[Notebook fan does not turn] Reasons for notebook fan not turning Notebook fan not turning solution
Notebook fan not turning will make the interior of the notebook unable to dissipate heat in time, which will cause Affect the work efficiency and performance of the notebook, even if there is a radiator, it is useless. Therefore, I will share with you the reasons and solutions for the notebook fan not turning. Let’s first understand how a laptop fan works.
The working principle of the notebook fan
The notebook fan is a dual heat pipe system, and the keyboard convection cooling fan. The rotation of the notebook fan is related to the CPU temperature. The fan will only rotate when the CPU reaches the warning temperature, that is to say, the fan will rotate when the CPU is in use. If the fan of the notebook does not rotate, it is likely to cause the computer to restart, freeze, and in severe cases, the CPU and some components will be burned.
Causes and solutions for notebook fans not rotating
1. If the notebook does not rotate, you should first consider whether the fan is broken. Just take it to repair or replace one.
2. If the fan is normal but does not rotate, there may be three situations:
a. There is too much dust in the fan. When cleaning, remove the fan from the heat sink, open the oil seal on the bottom, wipe them off with a cotton swab or paper, etc., or use a wooden toothpick to slowly wipe off the dust.
b. The fan shaft is rusted. Take the fan apart and apply some pomade on the shaft. Generally, use a straw or tweezers to dip in lubricating oil, and drop a drop of lubricating oil on the axis.
c. The reason for the motherboard. The minor plot is only the damage of the power supply transistor, and the complex involves many components, such as temperature control circuits. In the repair of IBM notebook, the related circuit fails. For example, if there is a problem with the temperature monitoring circuit of the H8, a Fanerror error will be reported. At this time, it can only be sent to a professional repair shop.
My Words: This is a question that many newbies love to ask. Most laptops implement BIOS-level hardware power management. Taking the CPU cooling fan as an example, it is different from the fan on the desktop that rotates as soon as it is turned on. The fan of the laptop is only installed at the position of the CPU, and only when the BIOS detects that the temperature of the CPU exceeds the manufacturer’s. The fan will only start when the preset value is set, so it often turns and stops, which is normal. Some manufacturers’ fans can even adjust the speed according to different temperatures, so as to reduce the power consumption to a minimum. So if a friend encounters this situation, don’t worry, it’s normal.
