What if the computer is afraid of humidity? The motherboard also has dehumidification function.

In the rainy season, computers are affected with damp, mainly in monitors, memory, keyboards, hard disks and so on.

Display a black screen

Phenomenon: The power indicator of the monitor lights up after the machine is turned on, but the screen is unresponsive.

Cause: In this case, it is mostly a memory problem. The humidity in the air is too high, which leads to slight oxidation on the surface of the gold finger of the memory stick. With the expansion of the oxidation phenomenon, the memory stick and the memory stick are in poor contact, and finally there is a memory alarm and a black screen. Solution: When starting the machine for maintenance, use an eraser to wipe the gold finger of the memory stick. After inserting the memory stick, you can also use a glue gun to seal the gaps on both sides of the memory stick with glue to reduce the contact surface between the gold finger of the memory stick and the air. This is also the reason why brand machines do this. It is very rare for a good brand of machine to have this kind of fault.

The display screen is blurred.

Phenomenon: the first display is not bright, and the image will be displayed after a few minutes; At first, the image was blurred, and it took about 20 minutes for the image to be completely clear.

Reason: It is also because the weather is humid and there is too much moisture in the air. If the monitor is not used for a long time, water vapor will accumulate in the tube socket of the picture tube, resulting in slight oxidation of the pins. At the beginning of power-on, the contact resistance between the pin and the socket is too large, and the voltage applied to each pole of the picture tube is insufficient, so that the image can not be displayed normally. With the increase of the temperature in the display, the water vapor in the tube socket is evaporated, and the pins of the tube socket and the kinescope return to normal conduction, so that the image can be displayed normally. Solution: Just turn it on for a while; Or the monitor is not turned off when it is turned off, so that it is in a standby state.

Monitor strange calls

Phenomenon: Consumer Miss Zhang reported that she was on a business trip for half a month in mid-May and came back to find a terrible "snapping" sound on the display. Could the computer be broken?

Reason: The reporter consulted a professional on this matter. Mr. Xu, a maintenance engineer in charge of computer after-sales service of Changyi Technology, said that due to the recent heavy rain, the air humidity is high, the monitor is wet, and the image instability is a natural phenomenon, which is not a big problem. Solution: In this weather, keep the computer off the ground 10 cm and one or two fists away from the wall to ensure that it is turned on for several hours every day, and the machine can dry the moisture by its own heat.

Keyboard failure

Phenomenon: I haven't used the computer for a long time recently and found that the keyboard is partially out of order. After blowing with a hair dryer for a while, some key functions were restored, but they soon failed.

Cause: Poor key contact caused by humidity. Solution: Desktop keyboard, you can try to solve the problem with a hair dryer. If it's a laptop, it's best to send it to a professional organization for processing.

Hard disk not found.

Phenomenon: The boot prompt cannot find the hard disk.

Reason: There are many reasons why the system can't find the hard disk. It may be that the IDE controller of the motherboard is damaged, the data cable of the hard disk is of poor quality or broken, the interface communication chip of the hard disk is damaged, and the power supply of the hard disk is insufficient. In the rainy season, it is more likely that the D plug supplied by the hard disk is oxidized and rusted due to humidity, which leads to poor contact and high contact resistance, resulting in low voltage actually supplied to the hard disk. Solution: put the computer in a ventilated place and turn it on for about two hours every day.
