What if the desktop is not used for a long time (2 years)
1, turn on the computer regularly, especially in the wet season, otherwise the chassis will be short-circuited when it is wet, and the computer that is often used is not easy to break down. But if there is no lightning rod around the house, don't turn on the computer when it thunders and unplug all the plugs.
2. Pay attention to heat dissipation in summer, avoid using the computer for a long time in a room without air conditioning, and pay attention to antifreeze in winter. Computers are actually afraid of cold.
3. When the computer is not in use, cover the monitor, chassis and keyboard with a breathable and strong covering cloth to prevent dust from entering the computer.
4. Try not to switch the machine on and off frequently. When not in use for the time being, simply use the screen to protect or sleep. When using the computer, don't move the chassis, don't let the computer shake, and don't plug in all powered hardware devices except USB devices when booting.
5. Using a three-pin power socket with overload protection can effectively reduce static electricity. If your hands can feel static electricity, use an enameled wire (that is, the one with plastic outside and copper wire inside), one end of which can be wound on the back plate of the chassis, the fan outlet, and the other end is preferably wound on the tap water pipe. If you can't touch the tap water pipe, look for it nearby, as long as the metal object can touch the soil.
6. Clean and dry: clean all the hardware dust in the host (including the host power supply), and the display surface needs to be clean.
7. Turn the machine on and off periodically to activate computer components.
8. Packaging: The mainframe and monitor are sealed with plastic to prevent moisture; Then it is packed with foam and then boxed, with the purpose of shock resistance and compression resistance.
Because computers and their monitors are precision electronic devices, they are greatly influenced by dust, temperature and humidity. Always power on to preheat and activate components. Never use it, it will have a certain impact on the life of the whole machine, and even burn out the circuit board. Basic knowledge of idle computer maintenance
It is very harmful to the computer placed near the window sill. Try to put them in a dark and dry corner, or draw curtains when you leave home to avoid the computer host and its monitor being exposed to the sun. In addition, whether this computer is in use or not, a more spacious living room and a good heat dissipation environment are beneficial to it. If there is more dust, the heat dissipation of the hardware will be bad, and the operation of the computer will naturally be affected.
Besides temperature, the influence of dust is also very important. Because the cover of dust may hinder the heat dissipation of hardware, and even cause the danger of short circuit, it will have adverse consequences for almost all computer accessories, so as to affect the life of each computer accessory. Therefore, before preparing for a long trip, everyone can thoroughly clean the room and ensure the cleanliness of the room. Then, it is best to cover the monitor and the host with a dust cover, which can prevent dust from entering and avoid being exposed to strong light for a long time.
In addition, if you don't use the computer for a long time, you may get wet, which can't be ignored, because it brings no less harm than the first two situations. If there is someone at home, you can turn on the computer every two or three days to dissipate the moisture. Of course, if everyone goes out to have fun, we can only try to put the computer in a dry room. But don't forget to clean up after the long vacation. Also remind everyone that you must remember to cut off the power and connection of the computer before going out to prevent accidents. Because of the changeable weather in spring and summer, the thunderstorm will come soon and will not be discussed with us. Therefore, not only computers, but also other household appliances.
