Notebook CPU maintenance tips
The notebook cpu is the computing core and control core of the notebook computer. Although the mainstream processors all have the protection mechanism of temperature overheating and automatic shutdown or frequency reduction, when the high temperature environment is used for a long time, the notebook cpu will be lost, how to use and maintain the cpu correctly. It is a problem we need to pay attention to.
1, to focus on solving the heat problem to maintain cpu data recovery training
To ensure the stable operation of the computer, we must first solve the heat dissipation problem. High temperature is not only an important killer of cpu. For all electronic products, if the high temperature generated during work cannot be quickly dissipated, it will directly affect its service life. We know that the heat generated by the CPU during working hours is quite terrible, especially for some high-frequency processors, and the heat generated during work is even more amazing.

Therefore, in order to make the cpu better serve us, the heat dissipation is indispensable. The normal operating temperature of the cpu is 35 ~ 65 ° C, depending on the cpu and different frequency, so we have to choose a good radiator for the processor. Not only the quality of the cooling fan is required to be good, but also the product with good heat sink material.
Usually, the heatsink of the boxed processor can meet the heat dissipation requirements of this product, but if you want to overclock, then the heatsink of the cartridge is absolutely unable to meet the heat dissipation requirements. A product with better heat dissipation performance.
Although cpu overclocking has become a compulsory course for many players, I believe that if your cpu is sufficient, it is not recommended to overclock the processor. Because even if your radiator is good enough, the CPU life after overclocking will be shortened. In addition, we can use the speed measurement software to timely detect the temperature of the CPU and the speed of the fan to ensure that the working state of the heat sink and the temperature of the CPU are known at any time.
In addition, we also need to ensure smooth air circulation inside and outside the chassis, to ensure that the heat generated inside the chassis can be brought out in time. The heat dissipation work is done, which can reduce the number of unexplained crashes.
2, to choose the right weight of the radiator to maintain cpu
In order to solve the problem of cpu cooling, it is necessary to choose a good radiator. However, when we want to choose a radiator, we must also purchase the right product according to the actual situation of our computer. Don't just pursue heat dissipation, and buy a "luxury" product that is big and heavy. Although these products are easy to use, they have considerable weight, so long time will not only cause incompatibility with the CPU, but also easily crush the vulnerable shell of the CPU. I have encountered such a fault.
A computer bought two years ago, configured as Intel Pentium 4 2.4c ghz, MSI 865pe chipset motherboard, Seagate 80gb pata hard drive, colorful r9550 graphics card. Recently, the 6-channel sound card that comes with the motherboard has been silent, and it has been found that the sound card chip has a problem. I bought a new four-channel pci sound card in Computer City. I don’t need too much technology to change a sound card. So I put the chassis down, unpacked the chassis, unplugged the old sound card, and replaced it with a new sound card. Screw the screws and put them in the chassis. After the boot, enjoy the "Sound of the Sound" brought by the new sound card. Who knows that pressing the power switch, the computer is powered on, but the display is a "black face", there is no display, too no "face"!
Recalling the operation process just changed a sound card, and did not perform other operations. According to the reason, there should be no hardware damage. Most of the faults are caused by poor contact. The failure of the black screen of the display for poor contact is generally concentrated on the cpu, memory and graphics card, should focus on checking the contact of these accessories. So put the computer flat again, open the chassis, clean the cpu cooling fan, graphics card cooling fan; remove the graphics card, memory, sound card, cpu, etc. on the motherboard, use the brush to sweep the various slots on the motherboard Dust near. Then put these accessories back to the motherboard, boot, and there is a long-lost "Energy Star" pattern on the display. It’s not surprising that everything starts up and it looks like a glitch!
After installing all the accessories, erect the chassis, oh! "Black face" appears again. Put the computer down again, re-insert all the boards, turn it on, and the computer is all normal. What is going on? After several trials, it was found that as long as the computer was leveled, the computer was all right, and the above failure occurred after the chassis was upright. According to the fault phenomenon, it can be analyzed that there is a local contact failure, so the memory is unplugged, the golden finger is wiped with an eraser, and then inserted back into the memory slot; then the graphics card and the cpu are unplugged, and the same method is used for processing. The result still does not solve the problem. But the huge cooling fan on the cpu caught my attention. In order to increase the heat dissipation effect, I chose a copper heat sink. The heat conduction performance of copper is excellent, but the density is large. Therefore, the weight of the copper cooling fan is also compared. Large, it is easy to make the slot deform, will this be the reason?
Since the cpu is mounted vertically on the motherboard, when the motherboard is laid flat, the center of gravity of the entire cpu together with the cooling fan is on the motherboard, and no other problems occur; and if it is a vertical chassis, the motherboard is placed vertically, and the CPU is connected to the motherboard. Vertical, therefore, the center of gravity of the cpu and the cooling fan does not fall on the main board. The long-term center of gravity is downward, and the weight of the copper cooling fan is large, which may cause the reed in the cpu slot to deform for a long time. malfunction. Guess the guess, or give it a try. I think that when the chassis is laid flat, it works normally. When it is upright, it will crash. It may be caused by the high quality of the CPU cooling fan and it may not be in good contact with the slot.
3, to do a good job of decompression and shock absorbers to maintain cpu
While doing a good job of heat dissipation, we must also do a decompression and shock absorber work on the cpu processor. Cpu died in the tragedy of the cooling fan buckle pressure, mainly in the cpu core was crushed. Therefore, when installing the radiator, pay attention to the uniform force, the pressure of the buckle should be moderate, and the buckle can be carefully adjusted according to actual needs. In addition, the speed of the fan can reach 6000 rpm. At this time, there is a problem of resonance. For a long time, the cpu and the heat sink cannot be tightly combined, and the cpu and cpu sockets are in poor contact. The solution is to choose a regular manufacturer. The cooling fan produced should have the correct speed and the fixture must be installed correctly.
4, diligently remove dust, use silicone grease and other to maintain cpu
Dust should be removed frequently, so that it cannot accumulate on the surface of the cpu, so as not to cause a short circuit to burn the cpu. Silicone grease should be applied to the core of the cpu surface when it is used. A thin layer can be used. Excessive amounts may leak into the cpu surface and the slot, causing damage. The silicone grease will dry out after a period of use, and then it can be removed and reapplied with silicone grease. Improved silicone grease should be used with care, because the modified silicone grease is usually added with carbon powder (such as pencil refill powder) and metal powder. At this time, the silicone grease has the ability to conduct electricity and penetrate into the cpu surface when the computer is running. The consequences on the capacitor and the slot are unimaginable. Usually pay attention to the static electricity on the body when playing with the cpu, especially in the autumn and winter seasons. The elimination method can be to wash the hands beforehand or touch the conductors of metal water pipes for a while to ensure safety.
