What should I do if the keyboard of my mobile phone gets into the water What should I do if the keyb

First of all: crashing and water ingress are the two taboos of mobile phone use, among which mobile phone water ingress is the most serious. After the phone gets into the water, the first thing to do is to turn off the power immediately, of course, you can't press the power off button, but directly remove the battery.

This is because as soon as you press the power off button, the mobile phone will be powered on to work, and it is likely that a short circuit will occur, causing damage to the mobile phone, and then send it for repair as soon as possible. 2: If the warranty period of the mobile phone has expired and you don't want to send it for repair, you can boldly disassemble the mobile phone!

The first thing you need to do is find a clean little box that holds the tiny screws that have been removed. In addition, a clean white paper should be laid on the desktop, and other clutter on the desktop should be cleaned up. Now unscrew off the most obvious screws on the surface of the phone (usually hexagonal) one by one and put them in the small box.

Screw one to see the other, the size, length, and installation position should be remembered. Once you're done, place your phone on the paper and slowly open it layer by layer. Serious Warning:

The most important thing about this step is not to open! Don't be in a hurry! The most important thing is to see clearly and remember where each part is opened!

Including shape, direction, front and back! If you are afraid that you will not be able to remember, you can draw a box on the white paper to mark or even write instructions! In addition, don't pull the wire hard, look at both ends of the wire socket, there are generally small tongue protrusions.

Use oblique forceps or other tools to carefully lift the little tongue upwards, alternating the ends without too much force. Pick up the rear line and it will naturally loosen. After opening, wipe the mobile phone parts with facial tissues, and then blow them with a hair dryer for a few minutes, in order to ensure that all the internal parts have been dried, it is advisable to air dry the mobile phone for a few more days, and clean the mobile phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together.

Then use a heat gun or hair dryer to dry the circuit board, and then power up the test machine, and most mobile phones will work normally. 3: If it falls into the sewage, it should be cleaned immediately, and the dirt that can be seen should be cleaned first, and the impurities attached to the pins of the components will be brushed off with a brush, and then the circuit board will be scrubbed with an alcohol cotton ball.

Then use an air gun to dry the circuit board, and then repair and solder all the chips before proceeding to the next step of repair.

It is best to have smeared water, use industrial alcohol with alcohol, and do not spray alcohol on the back pad of the keyboard, it will shrink. Do not use fans, do not use hot air, Hui to cause secondary injury. It is best to spontaneously combust and air dry.

<>1.Disconnect the power supply: First, disconnect the keyboard from the power supply immediately. If it's a desktop computer, you can turn it off and unplug the power cord. If it's a laptop, turn it off and unplug the battery, disconnect the charger.

2.Wipe the surface: Use a soft, clean cloth or paper towel to gently wipe the outer surface of the keyboard to remove moisture. Make sure you don't let water droplets get inside the keyboard.

3.Handling inversion: Turn the keyboard upside down to remove as much residual liquid as possible. Gently tap or shake the keyboard a few times to help drain the moisture out of the suffocation.

4.Absorb moisture: You can use a vacuum cleaner or suction appliance that absorbs water very well and place it close to the surface of the dust cover macro keyboard to absorb the residual moisture. Make sure that the suction collector is not electrostatically charged to avoid further damage to the keyboard.

5.Avoid using hot air to dry: Do not use a hair dryer or other heating device to speed up the drying process, as the high temperature may damage the circuitry and components inside the keyboard.

6.Drying time: Place the keyboard in a well-ventilated area and let it dry naturally. You can wait for at least 24 hours to ensure that the keyboard is completely dry. The drying process can be speeded up with the help of a fan or air conditioner.

7.Test the keyboard: When the keyboard is completely dry, reconnect the keyboard and test if the individual keys are working properly. If you notice any issues with your keyboard or keys that don't press properly, consider replacing your keyboard.

Please note that the above methods may not be able to repair the keyboard if it is severely damaged or if there is a short-circuit in the circuit, etc. In this case, you may want to consider replacing your keyboard or seeking a professional repair service.

This phenomenon is generally due to dirt on the road board or conductive plastic, or because drinks, water and other things flow into the keyboard, so that the two cannot be connected normally. It is also possible that some keys cannot be used due to a breakpoint in the circuit board in the keyboard.

The steps to clean up the dirt are as follows:

1) Disassemble the keyboard. Note that when opening the keyboard, be sure to turn the button side (that is, the side we operate) down and the circuit board up, otherwise the conductive plastic on each key will fall off one after another, causing trouble for your repair.

2) Open the circuit board, the circuit board is generally made of soft plastic film, engraved with slag with key lines, with the best concentration of more than 97 alcohol cotton (more than 75 medical alcohol cotton can also be, because I have used, but it is best to use high concentration of alcohol cotton) gently scrub the road board twice. For the failure of the key part of the line, take care of it a few more times.

3) Check the conductive plastic of the failed part of the button, and if there is a lot of dirt on the upper area, use alcohol to scrub it too. Assuming that the conductive plastic is damaged, then the author suggests that you can replace the conductive plastic on the infrequently used keys to the damaged part, although this "tear down the east wall to make up the west wall" measure can not make the keyboard play all the functions, but at least can extend the life of the commonly used keys.

4) Remove the dirt in the inner corners of the keyboard, tools can be brushes, small brushes, etc., but pay attention to the action should be gentle.

5) Check whether the soldering module has false soldering or desoldering, and if you can use an electric soldering iron, you can repair the soldering work. Of course, this step is only applicable to friends who can use an electric soldering iron, and friends who can't use it, please skip this step.

6) Install the keyboard. One thing to note here is that you must wait until the alcohol has evaporated.

Now with the progress of science and technology, people's work is becoming more and more intelligent, computers have become important office items, and people will use computers more in their lives to browse information, play games, and watch movies. Many people sit at the computer for a long time, so they will put the water cup next to it to rehydrate in time. At this time, Hu Ji is prone to accidentally knock over the water cup and spill water on the keyboard, and some netizens said that the keyboard is flooded, will it cause the keyboard to malfunction?

How can I make the keyboard resume normal use? Next, let's take you to understand how to solve these problems. <>

First of all, there are two kinds of keyboards, namely wireless keyboards and wired keyboards, if the wired keyboard is water, because it is conductive when connected to the computer, the connection wire of the keyboard should be unplugged immediately after the water is in, so as to ensure that the power is cut off immediately, so as to prevent more serious harm to the computer. If it is a wireless keyboard, you should disconnect it immediately and turn off the keyboard. <>

When the keyboard is powered off, turn the keyboard upside down so that water can run through the gaps between the keys on the keyboard. At the same time, I should be careful not to be anxious, do not shake the keyboard too hard, this behavior will be counterproductive, causing water to flow deeper into the keyboard and destroy the use of the keyboard. After the inverted keyboard allows the water to flow out fully, use a paper towel or cotton swab to dry the water in the gaps, and if there is a hair dryer, blow the water on the part where there is water to evaporate the water or we can put it in the sun to dry.

Remember not to blow hot air for too long, because most of the keyboard is made of plastic, which may cause damage to the structure of the codebook. When cleaning the keyboard, you must be patient to ensure that the water is evaporated, and you can't be in a hurry. If you do need it, it is recommended to replace it with another keyboard at this time.

After the above water removal operation, it is expected that the water in it can be evaporated in about 3 to 5 hours, and then when it is taken back for installation, it must be carefully checked to see if everything is normal. At this time, you can continue to use the keyboard normally. <>

The above is the process of dealing with the water ingress of the keyboard, but it is recommended that you put the water cup a little farther away as much as possible when using the computer on weekdays to prevent water splashing on the keyboard, especially the keyboard of the laptop is very troublesome to deal with.

1. Cut off the power supply immediately. There is a wiring in the keyboard, and if it touches water, it is easy to short-circuit, so the first thing you need to do is to cut off the power immediately.

2. If there is not much water, you can ignore it for the time being, first take the keyboard in your hand and turn it upside down, shake the water in the keyboard hard, and then put it aside, you can't use it immediately.

3. Carefully disassemble the keyboard, wipe (absorb) the water inside with a cloth or paper towel, especially the plastic circuit board inside the keyboard, if there is a hair dryer, then use the hair dryer to dry the water inside, and then install it as it is.

4. If it is poured into the drink, because the drink generally contains more sugar, it is easy to be sticky, so you have to take off the keycaps, the keycaps of the membrane keyboard can generally be directly disassembled by hand, after the keycaps are removed, you must remember the location of the keycaps, do not install the wrong ones, and take them to clean with water.
