What is the appropriate temperature for a notebook?

The temperature of notebook is generally between 55 and 60, and that of hard disk is generally between 40 and 45.

Five principles of notebook maintenance in hot summer

The hot summer is unbearable. In fact, in terms of notebook computer maintenance, it is not uniform. Different environments and seasons have different methods. The same high temperature in summer also puts forward certain requirements for the maintenance of notebook computers. Today, the author focuses on several problems that should be paid attention to in summer notebook computers:

First, the influence of sweat grease on the laptop shell.

As we all know, due to the high temperature in summer, people sweat very easily and secrete a lot of oil. If the notebook shell is often sweaty and greasy, it still has a considerable impact on the notebook shell. However, I want to point out that in this respect, the low-priced notebook computers made of ordinary engineering plastics are the most affected, while other high-grade notebooks made of aluminum-magnesium alloys are not affected much. This is determined by the material characteristics of engineering plastics. Engineering plastics not only have good flexibility, but also have the advantages of strong structure and wear resistance. However, poor corrosion resistance is a common problem of all plastic products. The corrosion of sweat and grease on plastic will make our notebook computer look uneven in color and appear ugly in color such as black spots. The solution is also very simple, that is, regularly wipe the shell of the notebook computer with high-concentration alcohol or a special cleaner with reliable quality. Generally, we can buy more than 86% high-concentration alcohol from pharmacies, because the water content of this alcohol is very low, and because of its physical characteristics, it will evaporate quickly and will not have any impact on the circuit of notebook computers.

Second, the laptop is lightning-proof in summer.

There are many thunderstorms in summer, so it is also very important to pay attention to lightning protection when we use notebook computers. Theoretically, when using telephone lines to dial up the Internet, laptops are most vulnerable to lightning strikes. So you must pay attention to using modem to surf the Internet in thunderstorm weather. In addition, sometimes the power supply current will be very unstable due to thunderstorm weather. Although all notebook computers have their own power adapter transformers, if there is instantaneous high voltage and strong current due to the influence of lightning, the power adapter of the notebook computer will be lightly burned and the power circuit of the notebook computer motherboard will be seriously damaged, so the safest method is to develop a wiring board with automatic overvoltage and power-off protector. In this way, when a strong lightning strike produces a strong current, the protector on the circuit board will automatically trip and power off, protecting the notebook from being damaged.

Third, rainproof and moistureproof laptop in rainy season.

There is a lot of rain in summer, so it is particularly important for us to take our laptops out. Because moisture can be said to be the number one killer of notebook computers! So you must use a laptop carrying case with waterproof and moisture-proof function. Generally speaking, the computer bag that comes standard with notebooks and the portable bag that we buy through formal channels can achieve the purpose of waterproof and moistureproof. A suitable carrying case is very important for the moistureproof and dustproof of notebook computer, which can greatly prolong the service life of notebook computer.

Fourthly, the influence of high temperature environment on the life of lithium-ion batteries.

Theoretically, lithium-ion batteries should be charged in the temperature range of 0 C to 45°C and discharged in the temperature range of-20 C to 60 C. We know that the high temperature in summer has a great influence on the activity of lithium ions. The performance of lithium-ion battery will decrease when it is used in high temperature environment. If various operating conditions such as charging and discharging and ambient temperature are not maintained or will reach the rated range, the service life of the battery will be reduced, and the battery will not be used for a long time after normal charging. Therefore, we should first pay attention to the ambient temperature of the notebook computer. Secondly, if it needs to be used in a high temperature environment, try to use the power adapter to supply power to the notebook computer, so as to minimize the influence of temperature and environmental factors on the life of the lithium-ion battery.

Fifth, cool down, cool down, and then cool down.

By cooling, I mean to reduce energy consumption and temperature by setting the software of the laptop. First, setting a reasonable power management mode is the first step to help notebook computers dissipate heat by themselves. We can set the time to turn off the monitor, turn off the hard disk and wait for the system. This is very important and good for hardware. In addition, when the notebook computer is not used temporarily, the application of the notebook computer's suspension mode can play a dual role in saving electricity and dissipating heat. Secondly, we can reduce unnecessary energy consumption and reduce temperature by turning off unused external devices and ports. Temporarily turn off unused external devices, such as mobile hard disk and PCMCIA devices, and turn off serial port, parallel port or infrared port, which can not only save electricity, but also reduce calorific value and prolong the service life of components.

Finally, we can use some cooling software to help the laptop CPU, which is a big fever. There are many cooling software, and the effects are mixed. The main function of some cooling software is to shield some functions that we don't often use. This kind of software is prone to system logic errors. This kind of cooling software is not desirable. The main cooling schemes are CPU Cool, CpuIdle and waterfall, which are more reliable. Personally, I feel that CPU coolpad is more reliable and has everyone's demeanor.

The above points are just some maintenance methods and precautions for laptops in hot, hot and rainy summer. Notebook computer is an expensive product, and proper maintenance can greatly extend the service life of notebook computer. However, due to different environments, the maintenance of notebook computers should be tailored to local conditions, and different methods should be chosen according to their work and study environment and situation. This will get twice the result with half the effort.
