If the computer is not turned off, how long will it last?
At the moment of power-on, high-frequency current will be generated.
A: All electrical products will have high-frequency current impact at the moment of starting. Theoretically, it would be better not to close it frequently. Although it will not break down immediately, it will affect the service life of the parts. If you leave your computer on for a few years, there will be no problem.
For example, the server in the computer room, who has seen the server shut down after work. Generally, enterprise servers are not updated frequently, but only once in the last 5-6 years. In these 5-6 years, they will not be shut down except for restarting.
I'm not sure how long the computer will last without turning it off, but when I play games at school, the computer is always plugged in. It was okay at first, about three months! The battery doesn't work, just turn it off as soon as you unplug it, and then change it again!
Ordinary computers had better not be used for 24 hours, at least give it a repair time!
The above is just personal experience, maybe the computer is different and the result is different!
It doesn't matter. My computer never shuts down.
Computers are necessities of life, and it is normal to update them every few years!
Computers have brought convenience to our lives. Besides work, we often need to use computers. Do you need to turn off the computer? Xinglin, tell me about my daily operation:
First of all, Xinglin is an ordinary worker. He has a desktop computer for public use in the office. Generally speaking, when he gets off work, he will turn off the computer. There is no deliberate component, just a habit.
After work, Xinglin, as a photographer, uses notebooks more frequently. In many cases, because he hasn't finished his hobby, the notebook is generally not turned off. In order to open it, he can do it next time, unless he finishes his hobby, he will turn off the computer!
So if the computer is not turned off, will it affect the service life of the computer? Theoretically, it will. Although it is in standby state and the host is still running, I have not found much abnormality after using the notebook for several years, and it is still smooth. Personally, I think it's okay to shut down and rest without special circumstances, so don't worry about the impact. But if you don't use it for a long time, you'd better turn it off, avoid the battery from turning off because of excessive consumption, and charge the notebook regularly!
Especially for devices that are not turned off, such as ATMs and vending machines, they can be used normally for 8- 10 years. If it is a home computer or notebook computer, it is recommended not to turn it off for a long time.
Computer is the product of the combination of mechanical and electronic components. Computers are divided into home and industrial use, as well as servers. In general, if the daily frequency in the family is high, it will take about 5 hours, and the server is running 7×24, that is, 24 hours a day, seven days a day. Electronic components can be used for up to 65,438+00 years, but their functions will be reduced. It looks fine, but it's difficult to run. Strong outside and weak inside. I hope this answer can help you.
A friend said that when his computer was turned on and off, the speaker would click, but the same speaker didn't. Ask me why. Later, I went to the computer to have a look, and I was basically sure that it was caused by current. At the moment of power-on, high-frequency current will be generated, which will make the speaker sound.
Q: If the current is too large, will the computer break down?
A: All electrical products will have a high-frequency current shock at the moment of starting, but the time is very short, and theoretically it will not cause too much harm to electrical appliances. Generally, the sound is caused by the lack of choke in the power supply, which is convenient for changing the power supply.
Q: So the computer is turned off every day? Or is it always on?
A: Theoretically, it's best not to turn it off frequently. Although it will not break down immediately, it will affect the service life of the parts.
Q: Will not turning off the computer for a long time lead to premature aging of the computer?
A: In fact, the aging of electrical products does not mean that it is getting worse. A brand-new computer may not even turn on for 3-5 years. But if you leave a computer on for five years without turning it off, there will be no problem.
For example, the server in the computer room, who has seen the server shut down after work? Generally, enterprise servers are not updated frequently, but only once in the last 5-6 years. In these 5-6 years, they will not be shut down except for restarting.
Q: Will it not cause battery damage if the notebook is opened for a long time?
A: Theoretically speaking, it is much better to open the notebook for a long time than not to use it for a long time. There used to be a Dell notebook. Due to work reasons, 1 has been useless for many years. Later, it was found that the battery was hung up, and the battery life was only less than 20 minutes after charging. Another Lenovo notebook, which has been working for three years, has not been related, and the battery has been seriously attenuated, but there is no problem at all in the last two hours.
Q: Will there be radiation if the phone is not turned off for a long time?
A: Actually, to put it bluntly, as long as the temperature of all objects in nature is above absolute zero, they are constantly transferring heat to the outside world in the form of electromagnetic waves. This way of transmitting energy is called radiation.
The energy released by an object through radiation is called radiant energy. Radiation is calculated in roentgen (r) per hour. Computer radiation mainly refers to electromagnetic radiation, which usually has biological effects such as thermal effect, non-thermal effect and stimulation.
According to the regulations of the International Radiation Protection Association and the International Labor Organization, the safe intensity of electromagnetic field is 0. 1 1-0.3 microtesla (this is the safe limit of electromagnetic field when computer is contacted for 24 hours), and it is harmless to human body below this intensity.
A special research institute has tested the electromagnetic field intensity of the computer, and the results show that the electromagnetic field intensity near the screen is 0.9, while it is less than 0. 1 at a distance of about 5 cm from the screen, which is almost impossible to measure at a distance of 30 cm (this is the customary distance between the computer operator's body and the screen). Therefore, keeping the computer on will not cause harm to human health.
Speaking of the benefits of not turning off the computer, that's too much. For example, your company goes to work at 9: 00, and accidentally arrives at the post at 8: 59 in the morning. If you turn on the clock again at this time, I'm afraid you will kneel. Computers can clock in without turning on the monitor, even the fastest ssd boot speed is better than turning off the computer. When I go to work, I often open many web pages to look up information, or open many work-related forms, documents and so on. By the end of the day, the work was still unfinished, but there was no urgent need to work overtime. If you turn off the computer, you have to look for it again the next day, which is a waste of working time. So I usually leave my computer on and go to the company the next day.
In terms of computer life, I used to have two laptops at home. One was bought and turned on 24 hours, and the other was used by my wife. Her method is to turn it off when not in use and turn it on when necessary. Five years later, there is nothing wrong with the hardware of the two computers, and the battery life is similar. Some students asked what will happen in five years? I think five years of computer use is almost enough. As for computers that are more than 5 years old or even 10 years old, even if they are not broken, no one should continue to use them.
If you don't turn it off, the answer is that it will definitely shorten the life of the computer!
If you turn on the machine 24 hours a day, the service life of the component is certain, then its effective service life (working for us) will be shortened, which is equivalent to shortening the service life. At this time, some components are more prone to problems, thus shortening the life of the computer.
1. Motherboards are prone to dust accumulation, overheating and burning, and components working at high temperature for a long time will reduce their rated life.
2. The capacitor package on the motherboard is prone to Explosicum aging.
3. Chassis power supply, CPU, memory and other integrated circuits. The computer never shuts down, and the first thing that goes wrong is probably the power supply. If you can't start the machine suddenly or crash frequently, check the power supply first.
4. Hard disks, especially mechanical hard disks. There is a motor in it, which will cause mechanical wear and the hidden danger of track damage. Many computers are not designed to keep you on 24 hours a day. If the computer is not turned off for a long time, it will affect its service life.
If you don't turn off your phone for a long time, the chances of being disturbed by the outside world will increase. For example, vibration, thunder and lightning will all affect the computer, and the chance of accidental damage will also increase.
If the computer is not turned off, how long will it last?
This question is interesting. There are several kinds of computers, such as servers, desktops and notebooks. Do you mean a desktop or a notebook? Because the server is originally running 7X24 hours a day, it will not be turned off for several years.
As for its life span, it should be ten or eight years. For example, a server in the computer room of our company has been running for six years and has never been turned off. Even if there is occasional power failure, there is a backup generator and UPS to provide uninterrupted power supply. Servers are usually upgraded and replaced once every six years, so most servers are replaced before they die.
Desktop, especially self-assembled, because of the uneven quality of accessories, so the application of Konikin's law, that is, the worst quality accessories determine the life of the computer.
Home computers do not support 7X24 operation. If they have to run, it is estimated that there will be no big problem in two or three months. The most likely problems are cpu cooling fan and power supply. In addition, if the operating system of the home computer is not turned off for a long time, it is easy to crash. I remember when I was in college, a computer in my dormitory hung up to play games 24 hours a day and was often restarted because of a crash. When the desktop is not in use, it will go into sleep mode. At this time, only the CPU fan may be running. In this state, life depends on the life of the fans, and it is estimated that there will be no problem for one year.
After the notebook is closed, it can automatically enter deep sleep. It's okay if it's not turned off for several years, and the CPU fan can't turn. I have an Apple notebook, which has been used for two years and has never been turned off.
Other brands of computers should be similar, and it will not be a problem for several years. Even if it is used normally and works 24 hours a day, there should be no problem for one year.
Depending on the use environment, it is not a problem that the computer in the professional computer room will not be turned off for more than 5 years.
