The main reason is the high processing frequency of CPU and the long use time of computer. It is also possible that the cooling fan doesn't work.
For example, if you use WPS documents for a long time or play large games, the cooling fan may be inferior or the accessories may be aging.
Solution to computer fever: First, close the computer screen, close all running programs and stand by for a while. (Detailed steps: logout in Windows system, folding screen to sleep) Second, replace the new cooling fan. (Detailed steps: go to a professional computer accessories store to buy) Third, turn it off, wait for 5 minutes to 10 minutes before turning it on, and pay attention to saving the contents. Fourth, pay attention to the maintenance of various computer accessories, accessories have a life, overheating will lead to fever in different locations.
In short, it is to make the running frequency of C P U lower and the effect of cooling fan higher. In addition, Lenovo's computers have been professionally tested, and old computers that have been used for a long time may get hot because of aging accessories. If you have a product service card, you can go to Lenovo store for professional analysis and processing.
The cleaning of the computer dismantler may be damaged due to improper operation. Do not disassemble the machine. Professionals are advised to clean up the dust and garbage of the accessories in order to better dissipate heat.
2. What should I do if my laptop is overheated?
Heat dissipation has always been a big problem since the birth of computers, and with the continuous improvement of computer performance, this problem has become more and more serious. A foreign strongman once fried eggs in a notebook, which shows that the heating capacity of a dual-core notebook is indeed considerable. In fact, most of the computer crashes in summer are due to the high ambient temperature, which leads to poor heat dissipation and high internal temperature of the machine.
Heat dissipation is related to the stability of product operation and the service life of the whole machine. In summer, the heat dissipation of computers has become a big problem, especially the notebook with integrated structure. Players can blow the air conditioner with bare arms, but the computer can't run naked.
First, who is hot? First of all, we need to know where the main heating part of the computer is. Of course, CPU is the largest heat generator. However, for many years, many people have always thought that CPU is the hottest part of a computer. In fact, the heat emitted by CPU only accounts for about 7% of the total internal heat. The reason why the heat dissipation mode of the processor is emphasized is that it is a centralized heat dissipation product, especially the high-frequency multi-core processor which is widely used at present. If the heat dissipation of the CPU is not handled properly, it may lead to CPU burning, so we focus on the heat dissipation performance of the computer.
Secondly, the graphics card is also the main heating component, and the early graphics cards are not very strong, so manufacturers simply don't have to consider the problem of heat dissipation. However, now ATI Radium 4870 and GeForce 260 GTX are both powerful graphics cards, and heat dissipation has been put on their "important agenda". It can be said that the calorific value of the graphics card has now exceeded that of the CPU. Once the graphics card is overheated, it will be bright black, which will lead to the memory or core of the graphics card being burned out in serious cases. At that time, you were called invalid every day, and you shouldn't be called Lingling.
Thirdly, memory, hard disk and battery are also the main heating parts of the computer, but compared with the graphics card and CPU introduced above, the requirements for heat are not very high, but they are slightly better.
Graphics card temperature: above 70 degrees, especially when it is on. Be sure to check whether the video card fan and heat sink are normal, and the dust left by long-term use is also an important reason for the high temperature. If the temperature of the graphics card exceeds 90 degrees, please turn it off immediately for inspection to prevent the high temperature from burning the graphics card core or video memory.
Motherboard temperature: Northbridge chip is the most heated part, but compared with CPU and graphics card, the temperature is much lower, generally less than 50 degrees; If the temperature of the motherboard has exceeded 60 degrees, please immediately check whether the heat sink of the motherboard is loose and the wiring in the chassis is chaotic, resulting in low heat dissipation performance of the chassis.
Hard disk temperature: The hard disk temperature is generally below 52 degrees. If the heat dissipation performance of the chassis is poor, the temperature of the hard disk will exceed 58 degrees, which will lead to the unstable operation of the hard disk, and data may be lost at any time, which will seriously damage the service life of the hard disk.
3. What's the matter with the computer suddenly heating automatically?
Computers should be cleaned regularly. After using the computer for a period of time, I unconsciously found that the temperature of the computer had risen, and the "whirring" sound of the fan had been screaming. After reaching a certain level, the computer will shut down directly. This is a computer protection program at work. Without this protection program, the computer may "burn out" directly.
If this happens, please take it directly to the computer repair point and let a professional clean the inside of your computer. The price of cleaning is generally 30-50, depending on the difficulty of disassembling the computer. Remember: you can learn from other people's ash cleaning methods, and you can do it yourself next time.
After upgrading the computer hardware, the overall performance may be improved, but if the CPU is unchanged, improving its processing speed will definitely improve the CPU problem. For example, adding a memory stick to the computer, of course, we have made great changes in browsing the web, but the bigger the memory stick, the better. It depends on whether the CPU of the computer can bear it, or it will burn the computer.
Suggestion: With the advice of professionals, add memory chips appropriately. Make good use of the optimization master, he may give the computer a comprehensive test and temperature detection. If the temperature is too high, it will give an alarm, and the temperature of CPU, graphics card and hard disk will be displayed in real time. If it exceeds this reasonable temperature, it will be displayed in red, which can give us a reference when using it at ordinary times.
Pay attention to a when using a computer. Try not to play big games for a long time! B. The heat dissipation of the computer case must be good! C. Please turn off the computer directly if you don't use it for a long time. Standby will also heat up. If the environment is not conducive to heat dissipation, it will also damage the computer.
4. What should I do if my laptop is seriously hot?
Solution:
1, the computer will clear the dust during the knowledge period.
After using the computer for a period of time, I unconsciously found that the temperature of the computer had increased and the "whirring" sound of the fan had been screaming. After reaching a certain level, the computer will shut down directly. This is a computer protection program at work. Without this protection program, the computer may "burn out" directly.
2, computer hardware should pay attention to
After upgrading the computer hardware, the overall performance may be improved, but if the CPU is unchanged, improving its processing speed will definitely improve the CPU problem.
3. Make good use of the master of optimization.
The master of optimization may give the computer a comprehensive test and temperature detection. If the temperature is too high, it will give an alarm, and the temperature of CPU, graphics card and hard disk will be displayed in real time. If it exceeds this reasonable temperature, it will be displayed in red, so it can be used as a reference.
5. How to solve the serious fever of the notebook?
The hot summer is coming. In order to avoid the laptop crash and blue screen caused by overheating, and let our beloved laptop spend a cool summer safely, it is the key to effectively help the computer cool down. Let the notebook generate as little heat as possible and let the heat be discharged as soon as possible, which can be realized from both software and hardware.
First, the heat dissipation design of notebook. Notebooks are designed and produced according to the normal working temperature (0-35 degrees) and humidity (10%-90%) in the industry, and all of them have passed the most stringent high temperature and high humidity test.
Customers are not advised to use the notebook for a long time in high temperature and high temperature environment. The best use state of notebook is temperature (20-25 degrees) and humidity (10%-85%), which can achieve a longer service life than expected. Please don't use the notebook when the ambient temperature is above 35 degrees and below zero. Notebook computers can't work normally in such an environment. Too high or too low ambient temperature and humidity may cause damage to the laptop.
Based on the design requirements, the CPU of the notebook will automatically detect the temperature of the CPU itself. When the temperature reaches above 74 degrees, the notebook will run less and the fan will run at the lowest speed. When it reaches 78 degrees, the fan will run at the highest speed.
When the temperature reaches above 85 degrees, the system will perform shutdown protection. Second, set up a computer to minimize unnecessary energy consumption, thus reducing the temperature 1. Turn off unused external devices and ports, remove any peripheral devices that are not used for the time being, such as mobile hard disks and PCMICA devices, and turn off serial ports, parallel ports, infrared (IR) ports, Bluetooth and wireless network cards. This will not only save electricity and reduce calorific value, but also prolong the service life of components. Second, set up a reasonable power management method.
Make sure the power management mode of the notebook is set to Portable/Pocket. 3. Decreasing the speed of the processor can also reduce the calorific value.
Intel has adopted a technology called SpeedStep of PIII CPU, which can reduce the working voltage and running frequency of CPU, thus reducing power consumption and heat generation. For example, a Pentium M CPU with 1.8GHz can be reduced to 600MHz in battery optimization mode (it can also be reduced by software in AC power mode), and the calorific value of the CPU will naturally be significantly reduced.
When the notebook computer is set to the "portable/pocket" scheme, the notebook computer will make better use of the Speedstep technology of Intel CPU to optimize the power management of the system, so as to achieve the function of cooling down and saving electricity without reducing the performance of the system. In this case, the system will automatically adjust the speed of the CPU to meet the running requirements.
4. Closing unnecessary applications can also partially reduce energy consumption. 5. Upgrade the BIOS of the notebook.
Sometimes, fever means that the controller of the computer fan needs BIOS upgrade. The new BIOS can make the notebook fan work more efficiently.
If you think your notebook is getting more and more popular, you might as well go to the website to see if there is a corresponding new BIOS. Third, the shortcomings of using software to reduce frequency and temperature are also obvious. When the CPU cools down, it will greatly reduce the actual performance and bring disadvantages to the user's application operation. Therefore, under high load, it is impossible to reduce the CPU temperature by frequency reduction.
Heat dissipation software is the software that monitors the external instructions of CPU and has the highest priority in management. When it finds that the CPU has no external instructions, it will let the CPU enter the pause mode, giving the CPU time to "sneak off work" and the calorific value will decrease accordingly. When there is an external instruction, it will wake up the CPU and make it resume processing. There are many cooling software, but the commonly used cooling programs are relatively stable. Recommend CPUCool, CPUIdle and waterfall.
Specifically, you can go to the relevant website to download it, or you can discuss the relevant usage in the Dell BBS forum, so I won't introduce it in detail here. The advantages of software cooling are completely free and easy to operate, but at the same time, there are some shortcomings such as poor applicability and limited cooling effect.
Fourth, physical process cooling 1. Create a good notebook environment. When using a notebook, you should pay attention to the cleanliness of the surrounding environment. Usually, the ideal working temperature of notebook is 10℃~35℃, and the humidity should not be too high.
Especially in hot summer, we should keep the surrounding environment well ventilated and try to use notebooks in air-conditioned rooms. But we should pay attention to some details: when we suddenly switch from a low temperature place to a high temperature place, most items will condense.
In this case, please don't use the notebook immediately, because dew may damage the notebook. (In fact, most electrical appliances have this restriction, not just notebooks).
Summer generally refers to from air-conditioned room to outdoor, and winter generally refers to from outdoor to indoor. Note: Please don't use the notebook when it thunders.
Sudden high and low currents do the most damage to the notebook. Even if you don't use a laptop, don't connect the power cord, network cable and telephone line equipment to the laptop when it thunders.
2. Keep the air around the laptop clean and use an external fan to help cool it down. Grooves and openings in the computer case are used for ventilation. Please don't block or cover these openings, and there should be no objects near the exit of 15CM to keep the exhaust emission process smooth.
Clean the vents regularly to prevent blockage. Please don't put the computer on your knees, bed or sofa. Soft things will block the cooling holes at the bottom of the notebook, leading to the failure of notebook cooling.
Be sure to put your notebook on a hard and smooth surface. In addition, the keys of the keyboard are small radiators. If the book is placed on the keyboard, on the one hand, it blocks the heat dissipation channel of the keyboard, and on the other hand, tiny fiber dust is easy to fall into the gap of the keyboard, which is harmful and useless.
