How to repair keys on a Dell laptop. How to fix a laptop keyboard How to repair broken keys on a laptop keyboard

laptop keyboard or desktop computer- one of the most frequently used technical inventions. Write a letter, fill out a form on the site, play a game - for all this, it is simply necessary. But from prolonged use, the keyboard buttons break. Can you fix them yourself?

You will need

- thick needle;
- curved clip.

Instruction

Inspect the keyboard and determine the cause of the failure. Usually the button, breaking, just jumps out. It is necessary to consider in detail what exactly broke in this moment. Pay attention to the principle of fastening the buttons on the keyboard. The basis for the button is a small square-lock, which unfolds like a "clamshell". Mounting points are also marked on the base. The button itself has pins according to the size of the base mounts.

Take a thick needle to correct the situation if, when the button breaks, its “clamshell” has lost its properties, as the frames have come off. The task is to connect the two frames of the base again. Carefully and carefully, commensurate with the force of movement, insert the fastening pins of one part of the base into the recesses of its other part and fix this position.

After that, take a curved paperclip. It is needed in order to install the button after fixing the "clamshell" in the correct position. Slightly lift the “clamshell” with a paperclip and in this position, set the button from above. Press lightly until the latch clicks.

If the keyboard button "exploded" under the fingers and flew out along with the latch, then you need to disassemble the button. To do this, disconnect the “clamshell”-latch by snapping off one end and pulling the other out of the ears.

On the keyboard, find three tabs for the latch - one larger and two small. Take the latch and slide it onto the mounts, starting with the large one. Please note that the lugs are made of aluminum and break easily, after which the button repair turns into a keyboard repair.

After the latch is hooked on the large eye, lightly press until it clicks, push the other two fasteners. Then install the top of the button by simply aligning the slots of the "clamshell" latch with the protrusions of the cap.

We constantly use mobile PC in our daily life. In it, the keyboard is the part of the device that takes on the most mechanical impacts.

The most common causes of breakdowns

The keyboard on a mobile PC has approximately the same structure as on a personal PC. She, like any device, is very sensitive to all kinds of pollution, animal hair, crumbs, and especially liquid spilled on it. After a certain time of using the keyboard, the buttons on the mobile PC fail or simply fall off.

Also, the simple banal cleaning of the keyboard using a vacuum cleaner for this purpose can be the cause of breakage of the buttons on a mobile PC. Or a small child may accidentally tear off a key. Also, the cause of such a breakdown can be pets that live with you. This also happens quite often. But you do not need to immediately carry a laptop for repair. You can often do everything yourself.

Button structure

Before considering how to insert a button on a laptop, you need to know its structure and attachment features.

The button consists of the key itself, the mechanism for holding it and a spring element with which it can be raised and lowered. Also there is a special film with platforms and paths.

The mount consists of two parts. These two parts are fastened together in the center with small "antennae". They come out of the inner part of the mount and are inserted into special grooves in the outer part. Thanks to this design, they can move when you press them. The button itself is attached to opposite sides.

Consider how to insert a button on a laptop

If a button has fallen out on your mobile PC, you do not need to immediately panic. In many cases, the problem resolves itself. At home, you can also solve the problem of how to insert a button into a laptop. To do this, it is enough to have a simple paper clip with you. Before inserting a button on a laptop to replace it, the old part must be removed from the keyboard. Working with the buttons on a mobile PC requires more care, as they are flatter and can be damaged if pressed hard. The removal of the element is as follows. It is necessary to straighten the paper clip into a straight line and pass the keys under the lower platform. Now you need to pull it towards you, and the key will jump off its base.

Now let's figure out how to insert a button on a laptop, provided that all the "antennae" located on the "rocker" and the grooves are not affected. This is the easiest way. To do this, the button must be installed in the upper position on the base under the necessary fastening. After it falls into place, the key must be gently pressed down.

It should be noted that it is not necessary to apply force when installing the keys. Any pressing must be done smoothly and easily.

After installation, you need to carefully check the fastening of the replaced key. When buying new buttons, you need to check whether they will fit your laptop model. If you need to change several details, then it is better to do it gradually. In order not to confuse the location on the keyboard.

Before inserting a button on a laptop, you need to carefully look so that the plastic mount, which is located under the key itself, is in place. It may seem at once that it is very difficult to dock everything. But in fact, this is not entirely true, because in reality there can be only one correct option. You won't install anything else.

How to insert a large button

Consider how to insert a button on a large laptop. These are such keys as Space, Tab, Shift, Enter. In addition to the "rocker", which is made of plastic, they can also have a metal stabilizer. It is necessary so that the key is pressed evenly. On the inside there are two lugs needed to attach the stabilizer to them. Immediately you need to start its ends. Next, we put the antennae of the “rocker” into the grooves and put the button in its place by slightly pressing it.

The spacebar rests on several "rocker" and on the stabilizer. A situation may arise that the "rocker" can be disassembled. It is easy to assemble using a needle or a toothpick for this. One side must be inserted into the groove, and the second is installed using a needle.

Consider how to insert a button on a laptop in which the mount is made using metal brackets instead of a plastic swing. Mounting here is also easy. Only it should be noted, it will be more noisy.

How to fix a button on a laptop

It must be clearly understood that an attempt to repair a button will most often be only one. This must be taken into account before putting the button on the laptop. Before starting the necessary work, you must have the following tools available:

We place the broken mount on it workplace. We take a needle and a soldering iron. We apply the needle to the place of the broken antennae and see that it goes there a few millimeters. We heat it with a soldering iron and melt it into the mount. We bite off the unnecessary part of the needle. We clean off excess plastic.

Consider another option, how to put a button on a laptop. We heat the needle with a lighter and make a groove with it, in which you can put, for example, a lint or something like that. We put it in the groove and glue it with superglue

How to make a new button

If the button stops working, do not rush to immediately throw it away. Maybe she just sunk down, and she can be put in place. If not, then the button must first be carefully considered. If it just cracked a little, then it can be glued with simple superglue. Only the most important thing is that her contact is in the same place.

If the key cannot be glued, you can make it yourself. Consider how to make a button on a laptop yourself. To do this, you must have plasticine with you. From plasticine you need to make the necessary shape and fill it with resin. There you need to lower the contact. It must be installed correctly. To make it smooth, it can be trimmed with ordinary sandpaper. So, we figured out how to make a button on a laptop at home. In some cases, this is easier than taking your mobile PC in for repair.

If the button just fell out

If the button fell out of the laptop, you must perform these steps. With her reverse side there are grooves and latches. They have "rocker ears". Their purpose is to connect the button to the keyboard. If the key with the "rocker" has fallen out, they must be disconnected. Then the "rocker" is installed. It will have a button cover. They are interconnected by the grooves that are on them.

So, we figured out how to put a button on a laptop. As you can see, this is not very difficult to do, and in many cases you can solve the problem without contacting a service center.

I had such a need due to the fact that a number of keys in different rows, both alphabetic and numeric, stopped working for me. Most of all, I was afraid that the controller was damaged and I wouldn’t be able to repair the laptop keyboard, but I still hoped that the matter was in the keyboard itself

In this article, I will describe my actions, accompanying the text with photographs that I took specifically to make an informative, intelligible article about laptop keyboard repair.

Since I know firsthand that the laptop keyboard is the most often worn out part of the laptop. Perhaps there are people among the readers who are ready to repair the laptop keyboard on their own, which is why I decided to write this article in a reader-friendly style.

First you need to remove the keyboard, depending on the laptop model, the procedure will be different. Most often, the keyboard is screwed from the front panel, access to the bolts is usually closed by the front cover under the screen, which can be removed without much effort.

The keyboard keys are fixed on elevators, so to speak, which have four attachment points, both to the key and to the keyboard pad.

To remove the key, you need to carefully slip a small screwdriver or a tool suitable for this under it and make an effort by lifting the key up, as it were. In this case, the key will be released from the elevator locks and removed.
Be extremely careful, the mechanism of both the elevator and the key mounts is plastic and it will not be difficult to break it, especially if there is no experience

After you remove all the keys, you have to get the film out of the keyboard case and divide it into two parts.
The film is usually a book that unfolds and has a transition on one side. It is better to separate the film after preheating, for example with a hairdryer, since the parts are usually glued quite well

To repair damaged tracks, you will need a special highly conductive glue, ideally with a silver content, such glue you can find in the radio market or in specialty stores that sell everything for equipment and electronics repair. The price is not expensive, it cost me only 100 rubles to buy glue with silver in the composition, Kontaktol

Next, using a multimeter, on the probes of which I soldered the needles, we look for damage and breaks, carefully piercing the tracks to make contact on the track. The tracks on the keyboard are covered with microfilm, so you can’t do without piercing with a probe needle

After you find the damaged parts of the track, all that remains is to clean these places and carefully draw the track with silver Kontaktol and let it dry

Basically everything. We collect in the reverse order and rejoice. The price of a laptop keyboard is on average 2000 rubles, the repair cost me 100 rubles - the price of Kontaktol, there is even a lot of it left for the future, if anything ...
