I am from Jiangning, where is the maintenance point of Enshuo computer?

If it is still under warranty, you can call the brand customer service, and they will tell you the after-sales address and.

Physical lifespan: more than five years.

Value life: five years. It will be worthless. Configuration life: one to two years. Especially motherboards, CPUs.

Ways to extend its useful life:

1. If the continuous use of the home computer is too long, the temperature in the machine rises, and the heat is difficult to dissipate, which will cause the aging of semiconductor materials and the failure of the circuit such as short circuit.

Second, the anti-low temperature home computer often can not work below 0, but also prone to failure, if you want to use, you should use hot air conditioning insulation, so that it can work at normal temperature.

3. Anti-smoke and dust is the enemy of home computers, which may penetrate into the most important storage device of the computer - the hard disk, causing great damage to the hard disk. Therefore, smoking must be prohibited when using the computer; After using the computer, it is best to let it cool for a while before covering it with a dust cover; When the screen has too much dust, it is best to wipe it outward from the center of the screen with a anhydrous alcohol cotton ball; Keyboards and chassis should also be dusted regularly. Dust removal work should be carried out under power failure.

4. Anti-noiseAll noise sources such as the roar of the motor, mechanical vibration, whistle, and the start-up of the speaker will affect the operation of the computer, and it is easy to cause data loss and transmission errors.

5. Anti-magnetic should not place the computer around magnetic items such as color TVs, combined stereos, electric fans, etc. Because they generate electromagnetic fields when they work, they can cause damage to the information on the disk.

6. Anti-voltage fluctuation home computer should generally work under the voltage condition of 220V 10, and the voltage is too high or too low to overload or lose control. Therefore, it is best for qualified families to be equipped with stabilized power supply and uninterruptible power supply UPS. The power supply of the computer and the power supply of household appliances should be separated as much as possible to reduce the fluctuating impact of the starting voltage and peak current of the electrical appliances on the computer.

7. The lightning protection computer is the electronic equipment that is most afraid of lightning strikes, because the computer has no resistance to the static electricity released by lightning, and often due to the interference of static electricity, the computer components are not easy to find faults. Therefore, computer users should not only have the protection of the lightning protection device of the building, but also equip the computer with a lightning suppressor that can prevent atmospheric induction, and also lay an anti-static carpet in the computer room. However, in case of severe weather caused by lightning and lightning, it is best not to use the computer and unplug the power supply of the computer to ensure safety.

8. Once the anti-virus computer is infected with a virus, it will affect the normal operation of the computer, and at the worst it will eliminate the disk data and crash the entire computer system. Therefore, the computer must be anti-virus, and the main method is to use a special disk for the special machine and refuse to use other people's floppy disks; Newly purchased systems and software must be checked for viruses; Important data in the system should be backed up regularly; Do not allow the computer to execute programs from unknown sources, etc.

According to experience, the replacement time of computer products is three to five years, not necessarily the machine is broken, but the software and system functions are constantly upgraded, and the speed and capacity of the old computer hardware can no longer keep up, which is naturally eliminated. . .
