The life span of a general computer is: 1. The computer is assembled from multiple electronic components, but the life span of the components varies. Generally speaking, the service life of a computer is not less than 8 years; 2. If the maintenance is average , or the frequency of use is average, and the use time is generally about 5 to 8 years; 3. If it is well maintained and the frequency of use is not extremely high, it can be used for 8 to 10 years.
The life span of a general computer is:
In fact, there is no fixed number of years, and it depends on many factors. relation.
For example, factors such as the quality of computer accessories, frequency of use, whether the method of use is correct, and whether the dust in the computer is frequently cleaned. Next, we consider the case where the first- and second-tier brands are genuine and have acceptable hardware quality.
Under normal circumstances, as long as the desktop computer is well maintained and the frequency of use is not extremely high, it can be used for 8-10 years. Among the friends we have consulted here, there have been computers that have been more than ten years old.
If the maintenance is average or the frequency of use is average, the use time is generally about 5-8 years.
Although computers have a very long lifespan, generally after about five years, the configuration of desktop computers will fall far behind. Many new software and new systems will be difficult to use, and many people will think that they are not broken. computers are eliminated.
The above is a case of relatively good quality. In fact, on the one hand, current manufacturers may "deliberately" control the service life, and on the other hand, the quality of many things now is not as good as before, so the above data has dropped on average. It's basically ok for 1-2 years. Next we want to talk about the design standard life of the main components of the computer.
The first is the CPU. According to a person who has worked as a quality engineer in Intel’s CPU packaging and testing factory, for every 1 million healthy CPUs, the number will break within 7 years. No more than 500. And this is the duration with the lowest failure rate, so the standard lifespan of most CPUs must be more than ten years.
Then comes the motherboard. First-tier brand motherboards generally have a three-year warranty. Capacitors are the main electronic components on the motherboard that filter out interference and stabilize voltage. Its quality directly affects the work of the motherboard. The stability of the motherboard. At the same time, the quality of the capacitor also directly affects the life of the motherboard. Judging from a large amount of data, the life of a motherboard using high-quality capacitors can be extended by at least 2 years than a motherboard with inferior capacitors.
And as can be seen from the above figure, the lifespan of capacitors varies greatly at different operating temperatures, so the lifespan of a motherboard of 6-10 years should be a standard range. In addition, the motherboard involves the replacement of the cmos battery. The life of the cmos battery is usually 3-5 years.
Next, let’s talk about hard drives. What I’m talking about here is mechanical hard drives. SSDs are still too new, and the water is relatively deep, so I won’t discuss them for now. An online backup service provider has been established for more than five years and now has more than 25,000 hard drives in operation, so they have enough data to calculate the lifespan of hard drives. Here are just the results: If the hard drive is used continuously (7 x 24 hours), there is a high chance that it will have problems after three years. After four years of continuous operation, 80% of the hard drives are still functioning normally. After six years, half of the hard drives will fail, or it is normal to have half left, or there is a half chance that your hard drive can run continuously for six years.
Then there is the memory. The memory stick is a semiconductor, has no mechanical structure and no wear and tear. Damage rate is extremely low. The most common problem with memory sticks is the oxidation of the gold fingers. There is no reliable data on the standard lifespan. However, the lifespan of memory sticks may be the longest in computers. 5-12 years is not a big problem.
LCD monitor: The nominal service life of most LCD monitors on the market is 20,000 to 30,000 hours. In other words, if it is turned on 24 hours a day, it can only be used for 833 to 1250 days, which is less than 3.5 years. However, it cannot be turned on 24 hours a day for general household use.
Chassis power supply: There is no reliable data on the chassis power supply, but the lifespan of a high-quality chassis power supply is also very long, usually 5-10 years.
Based on the situation of each major component, the standard lifespan of a computer should be 5-10 years. However, hardware updates are relatively fast and may be replaced in less than five years!
