What should I do if my Dell laptop keyboard is bad on a rainy day?

Keyboard failure, part of the keyboard keys on the keyboard failure, this is the failure of the keys without any regularity.

Caused by the failure of some keys of the keyboard, most of this situation is the failure of the internal circuit board of the computer keyboard, this phenomenon is generally due to the dirt on the road board or conductive plastic, so that the two can not be connected normally. Other factors are also possible, such as: damaged keyboard plug, faulty wiring, damaged motherboard, CPU not working properly, etc., but they are not the main cause.

The former can be solved by trying the following methods, and the latter is generally related to computer malfunction or keyboard malfunction.

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

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

3.Check the conductive plastic of the failed part of the button, and if there is a large amount of dirt accumulated on the upper area, use alcohol scrubbing as well. Assuming that the conductive plastic is damaged, then the author suggests that the conductive plastic on the infrequently used keys can be replaced with 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.

Probably because of moisture, it is recommended to dry the keyboard a little on a sunny day.

If the keyboard is restored after drying, it means that it is damp.

In this case, because the circuit board is flooded, it is very likely that the circuit board will have to be replaced, and only then will there be no problem at all.

The keyboard of your notebook is not good on rainy days, it may be damp, it must be humid on rainy days, and then this keyboard may be a little damp, you can use a hair dryer to blow on the surface of the keyboard, it should be better.

If this situation occurs, it must be caused by the poor contact of your laptop keyboard due to humidity on rainy days, and you can dry it with a hair dryer.

Find someone to clean it, which means that it may be too dirty, and then the contact is not very good, and then you always feel uncomfortable, and if you find someone to clean it, it will feel like new.

Your Dell laptop keyboard is not working on a rainy day, what should I do? Then you can go to the repair shop to repair it, and you can't repair it yourself, and you can't repair it yourself, and it will be more serious if you repair it again.

That may be a bit leaky, and the humidity is high on a rainy day, which is more obvious!

Under normal circumstances, there should be no requirement for rainy days, if you feel that there is such a situation, first look at whether the current ambient humidity is relatively large, so there are some problems in the use process.

It may be that your keyboard is flooded, so you must find some dryers to dry it, otherwise it may damage some parts in it.

If your keyboard gets into the water, it is inevitable that the keys will fail, and you can take it to the after-sales store to test it.

If it's just a rainy day, then you have to consider the impact of humidity on the computer, and it is recommended that you go to the repair point to do a test

It's not good to use it on rainy days, whether it's because of the humid air. The position of the keyboard is a little timed out and not easy to use, of course you can use an external electric keyboard.

In this case, it is because the computer board has entered the water, in this case, it is very likely that the computer board has been damaged, just open it to take a look, if not, you have to replace it.

Hello, this your brother's after-sales customer service hit** and let them deal with it. They will arrange for personnel to come to the home to repair.

Dell notebook keyboard is not good on rainy days, it means that the internal, water vapor is caused, the keys are out of order, or the circuit is short.

If you have a Dell notebook, it's not easy to make rainy days, this is a complete coincidence, in fact, it doesn't rain or not? It doesn't matter much, saying that the contents may be damaged.

Is that your laptop keyboard watered, then you can only take it apart and repair it.

It is possible that the keyboard is not in good contact.

This may be caused by water ingress into your laptop keyboard, so it is recommended that you disassemble it for maintenance.

How to deal with laptop keyboard failure:

1. Boot the button, enter the BIOS, and check the BAI here to see if the keyboard is out of order. It also fails, then the du is the keyboard is broken.

2. If the BIOS does not malfunction and the operating system is abnormal, it is a system problem, and you can check whether the driver has dropped.

3. The notebook interface is bad or there is a problem with the motherboard.

4. If the control IC chip fails, you need to go to the maintenance center to deal with it.

5. There is a problem with the computer system itself.

6. If the above methods cannot be solved, you need to go to the after-sales center for testing and replacement.

1. First of all, immediately turn off the power of the laptop system.

2. Unplug the power cord and all external devices as soon as possible.

3. Wipe the liquid on the surface of the laptop keyboard and the machine with a clean rag or facial paper;

4. Regardless of whether the laptop can be used normally, it is recommended to contact the after-sales customer service center immediately after the test and arrange inspection and maintenance, so as to avoid sudden failures caused by oxidation and rust.

It may be that the internal moisture is not good, resulting in bad contact, and the keyboard is out of order, it is recommended to disassemble and clean it, if it still doesn't work, it can only be replaced.

You should be damp with the keyboard, the keyboard is full of printed circuits, if not, just change a keyboard, generally more than a hundred.
