Overheating of the notebook - more common problem than overheatingdesktop computer: laptops are more compact, and the air circulation inside the laptop is worse than inside the system case. What should I do if your laptop overheats?
Usually laptop overheating is a consequence of one of two main reasons: improper operation or accumulation of dust inside the laptop. Much depends on the model: some laptops initially did not think about the cooling system, so they heat more.
How can I tell if your laptop is overheating? The case of the laptop in such cases is heated more stronglynormal, the noise level increases during operation. The laptop starts to slow down under heavy loads (games, resource-intensive applications), hang, spontaneously reboot and shut down. To make sure that the reason for these "glitches" is really the laptop's overheating, install a program to measure the temperature of the notebook's components.
The normal temperature depends on the specific manufacturer and even the model of the component, but the approximate values are: 50-55 degrees for the hard drive, 75-80 degrees for the processor, 70-90 degrees for the graphics card, not more than 90 degrees for the chipset of the motherboard. If the temperature of at least one part exceeds the nominal value, your laptop overheats.
To avoid overheating, you need to use the laptop correctly. You can not put it on your knees when you work, orsoft surfaces (for example, a blanket): so you interfere with the air circulation, and the laptop starts to overheat. The laptop can be placed only on flat hard surfaces - a table, a special stand.
If the laptop gets warm even on the table, you can put something under its rear end to Increase the gap between the bottom of the laptop and the table and improve the air circulation. The same function is performed by special rubber feet for the laptop.
You can buy a special coolingnotebook stand with fan. Usually, these stands are powered by the USB port of the laptop, so no additional power supplies are required.
These measures should be sufficient if the laptop's overheating was caused by improper operation. If the laptop overheats due to the fact that its cooling system is clogged with dust, need to clean the laptop from dust. The problem is that you clean the laptop inhome conditions are not always real. If the laptop is under warranty, it can not be disassembled. You can, of course, try to clean it with a vacuum cleaner, working "blowing", or blow it out with compressed air from a can, but normally you can not clean it.
Even if the warranty period has already passed (or if you decided that the laptop will be better without a warranty, but will stop basking), you may not be able to disassemble the laptop yourself. Easiness of assembly-disassembly depends on specific model: some will calmly analyze even the amateur, and over some workers of service centers head break.
If you are not sure that you can normally disassemble a laptop, clean it and collect it back, it's better to contact the service center. Perhaps it turns out that Overheating of the laptop was caused not by dustiness, but by failure of one of the fans, in this case it will be necessary to replace the defective fan with a new one.
If only the processor is heated from all the details of the notebook, it is most likely necessary to replace the thermal paste: this will help prevent further overheatingprocessor. Many notebook manufacturers save on thermal paste, so proper application of a good thermal paste will help lower the temperature of the processor. Replacing the thermal paste requires disassembly of the laptop, in this case, again, the warranty is lost. If you are not sure you can replace thermal grease independently, it is better to contact the service center.
So that your laptop does not overheat, you only need correctly to operate it and from time to time to make preventive cleaning from a dust and replacement of thermal grease. Then even in the summer heat you will not have to face such a problem as overheating of the laptop.
