The keyboard is an integral device for operating personal computers and laptops. Failure of this component makes work and leisure time at the computer completely inconvenient. Are problems with the information input device removable? How to fix the keyboard yourself? We will examine this question in detail in this article.
Main types of faults
It's no secret that these devices can have different shapes And additional keys with the corresponding functionality. Even take the same multimedia keyboard, which has a number of special keys at the top. Pretty convenient, right?
But what should you do if several keys stop doing their job or the entire keyboard is completely out of order? Without a doubt, you can purchase a new device, but then you need to be prepared to spend 10-100 dollars on a new device. Why spend money if you can restore your old device to working condition? Prepare a soldering iron, Phillips screwdriver, tester and read the description of problem solving for several cases.
The keyboard doesn't work at all
The most common cause of failure is a broken wire connection inside the USB cable, which we are used to using to connect an information input device to a computer.
Important! Most often, the rupture occurs at the base of the keyboard itself or near the connection connectors.
In order to establish the exact cause of the breakdown, you need to look at the operation of the LEDs, which are usually located in the upper right corner of the device. If the keyboard is “working”, then all three lights should flash and go out when the computer restarts. If this does not happen, then you need to arm yourself with a multimeter (or any other testers) and test the cable. To do this you need to do the following:
- Turn the device over, take a screwdriver and unscrew all the screws that hold the cover.
- You will see a “film” in front of you with a large number of tracks. Also inside the keyboard is printed circuit board and a small microcircuit that is a black drop.
- The wire itself must be soldered to the board. We need to check the integrity of its connection to it. We take a multimeter, turn on the ohmmeter on it and call the desired area. You can also ring the diode, which is much more convenient because of the sound signal.
- If at least one “vein” does not ring, then replacing the defective wire cannot be avoided. You can try using wire cutters to bite off that part of the wire that is located where it passes into the keyboard body.
- If everything is in order with the wires, then the problem is most likely in the microcircuit itself. Then you will definitely have to run to the store for a new one.
- There is a possibility that the problem is with the connector itself. Inspect it carefully for defects and straighten the bent legs with a thin, hard object, if any defects exist at all.
We've sorted out bringing the entire device back to life, but how to fix a button on a computer keyboard?
The keyboard works, but not completely
We often spill something on the desktop, and it’s good if the liquid did not get on the keyboard from the computer, because if the keyboard gets wet, then several buttons or even all of them may fail to work. Also, strong mechanical influences, which sometimes happen by accident. What to do in all these cases? Let's talk about each method of how to repair a keyboard in detail.
Spilled liquid
Did your favorite tea end up on your input device? Immediately disconnect the gadget from the computer and wait until it dries completely. If after this several buttons become unusable, then the following recovery method will help you:
- Remove all keys to expose the space underneath. Use thin objects or loops of copper wire for this.
Important! If you are a novice user, we recommend that you save a photo of the location of the keys on your computer so that assembly goes smoothly.
- Set the keys aside and turn the keyboard over. Now unscrew about a dozen screws holding the cover.
- Remove the cover and the film with the tracks, wipe them very carefully with a cotton swab moistened with alcohol. Let the film dry completely.
- Again, take a cotton swab moistened with alcohol and wipe the area under the keys.
- All that remains is to put everything back together and check the device for functionality.
Mechanical influences
The keyboard device contains contact pads and conductive rubber. All of them are located directly below the keyboard buttons. Sometimes minor damage to paths can be repaired using special compounds, capable of conducting current. They are applied to conductive rubber tracks and bases. But repairs are not always possible if the device has been used for a very long time.
Important! Users who are fond of typing texts can completely forget about repairing it, since there is no point in it. Rapid wear and tear will return everything “to its place.”
Laptop owners periodically have a common problem - a key (or several at once) has fallen off. This happens for many reasons: careless actions, pets, children playing, the device falling, etc. Do not rush to service center, because replacing buttons is a simple procedure that you can do yourself.
Some keys need to be removed immediately when the laptop is flooded with liquid. Getting the button out is not a big problem: you just need to pry the key off with a sharp object; a small screwdriver or knife will do for this. But putting them back on later is quite problematic. To restore the keyboard, you need to familiarize yourself with the design of each individual button.
Single key design
All laptops are different, but the principle of attaching the buttons, as well as their design, are approximately the same. On the reverse side of each panel there are several fastenings for the pressing mechanism (rocker, lift, lock). If the button falls off without the rocker, then putting it back is not difficult: you just need to lightly press the button, directing the fasteners into the corresponding grooves.
Installing a flying button
The situation is somewhat more complicated if the part breaks, flying off along with the latch. To perform the repair, you will need:
- Disconnect the latch from the key.
- Put it in place.
- Lightly press the button (press until it clicks).
Falling heavy objects can sometimes cause the mounts on the keyboard itself that support the key rocker to bend. They are made of flexible aluminum so they can be easily repaired. It is important not to damage these aluminum fasteners, otherwise assembling the keyboard will be extremely problematic. This can only be done in .
When installing individual buttons special effort no need to apply: the keys are placed in their usual place with a slight click. Avoid pressing hard to avoid damaging the plastic fasteners.
Installing large buttons
Some keys (Ctrl, Shift, etc.) are large. To ensure even pressure, a metal stabilizer is used. Changing such a button is a little more difficult: before installation, you need to attach the iron bracket.
The space bar is attached to two locking mechanisms at once, and a metal stabilizer is also used. But this doesn’t make installing Spacebar any more difficult.
In some cases, the rocker (fastening mechanism) falls apart. Careless disassembly or a heavy object falling onto the keyboard leads to unexpected situations. Despite small sizes, the fastening mechanism is very simple and consists of only two parts. Using a needle, toothpick or nail file, the retainer can be easily assembled.
At self-installation keys should be extremely careful. Fragile plastic fasteners are small in size, so they are quite easy to damage. Excessive force should be avoided to avoid breaking the key. Otherwise it will cost much more.
The keyboard of a laptop or desktop computer is one of the most frequently used technical inventions. Write a letter, fill out a form on the website, play a game - for all this it is simply necessary. But the keyboard buttons break due to prolonged use. Can I fix them myself?
You will need
- - thick needle;
- - curved paper clip.
Instructions
We constantly use mobile PCs in our daily lives. In it, the keyboard is the part of the device that takes on the most mechanical stress.
The most common causes of breakdowns
The keyboard on a mobile PC has approximately the same structure as on a personal PC. It, like any device, is very sensitive to all kinds of dirt, 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 cause of breakage of buttons on a mobile PC can be a simple banal cleaning of the keyboard using a vacuum cleaner for this purpose. 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 don’t need to immediately take your laptop for repair. Very often you can do everything yourself.
Button structure
Before you consider how to insert a button on a laptop, you need to know its structure and mounting features.
A button consists of the key itself, a mechanism for holding it and a spring element with which it can be raised and lowered. There is also a special film with platforms and tracks.
The mount consists of two parts. These two parts are fastened together in the center by 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.
Let's look at how to insert a button on a laptop
If a button falls out on your mobile PC, there is no need to panic right away. 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 the button into the laptop to replace it, the old part must be removed from the keyboard. Working with buttons on a mobile PC requires more care, as they are flatter and can be damaged if pressed hard. Removing an element goes like this. It is necessary to bend the paperclip into a straight line and pass it under the lower platform of the keys. 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 damaged. This is the easiest way. To do this, the button must be installed in the upper position on the base under the required mount. After it is in place, the key must be gently pressed down.
It should be noted that you do not need to use 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 purchasing new buttons, you need to check whether they will fit your laptop model. If you need to change several parts, it is better to do it gradually. So as not to confuse the location on the keyboard.
Before inserting a button on a laptop, you need to carefully check that the plastic mount, which is located under the key itself, is in its place. It may immediately seem that it is very difficult to connect everything. But in fact, this is not entirely true, because in reality there can only be one correct option. You can't install anything differently.
How to insert a large button
Let's look at how to insert a button on a large laptop. These are keys such as Space, Tab, Shift, Enter. In addition to the “rocker”, which is made of plastic, they may also have a metal stabilizer. It is necessary to ensure that the key is pressed evenly. On the inside there are two ears necessary for attaching the stabilizer to them. You need to tie up the ends right away. Next, insert the antennae of the “rocker” into the grooves and put the button in its place by lightly pressing it.
The space bar is supported by several “rockers” and a stabilizer. A situation may arise that the “rocker” may be disassembled. It is easy to assemble using a needle or toothpick. One side needs to be inserted into the groove, and the other is installed using a needle.
Let's look at how to insert a button on a laptop in which the mount is made using metal brackets instead of plastic swings. The mounting here is also simple. Just note that it will be noisier.
How to fix a button on a laptop
It is necessary to clearly understand that there will most often be only one attempt to repair the button. This must be taken into account before installing a button on the laptop. Before starting the necessary work, you need to have the following tools available:
We place the broken mount on its workplace. Take a needle and a soldering iron. We apply the needle to the place of the broken antennae and make sure that it goes there a few millimeters. We heat it with a soldering iron and fuse it into the mount. We bite off the unnecessary part of the needle. Clean off excess plastic.
Let's consider another option on how to install a button on a laptop. We heat the needle with a lighter and make a groove with it, into which you can place, for example, lint or something like that. Place it in the groove and glue it with superglue
How to make a new button yourself
If the button stops working, there is no need to rush to throw it away immediately. Maybe she's just sunk and can be put in her place. If not, then first you need to carefully examine the button. If it is just a little cracked, then it can be glued together with simple superglue. The only most important thing is that her contact is in the same place.
If the key cannot be glued, you can make it yourself. Let's look at how to make a button on a laptop yourself. To do this, you need to have plasticine with you. You need to make the necessary shape from plasticine and fill it with resin. You also need to put the contact there. It must be installed correctly. To make it even, 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 for repair.
If the button just fell out
If a button falls out of a laptop, you need to perform the following steps. On its reverse side there are grooves and latches. They contain “rocker ears”. Their purpose is to connect the button to the keyboard. If the rocker key falls out, they need to be disconnected. Then the “rocker” is installed. There will be a button cover on it. They are connected to each other by the grooves that are located on them.
So, we figured out how to install 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.
Having learned the structure of the button and a number of simple operations for removing and installing it, the user will be able to independently fix a minor breakdown or replace the faulty key with a new one.
How to insert a button into the keyboard on a laptop
Laptop, unlike personal computer, has a built-in dialing device, the cost of which is significantly higher due to its compact dimensions and integral design. That is why its repair, including independent repairs, is constantly in demand and economically justified.
With prolonged use and active use, parts of the keyboard fall out or break, requiring replacement, quite often.
However, before you run to the service center, let’s try to figure out whether you can insert a button into the laptop keyboard yourself at home and, perhaps, save money and personal time.
Possible reasons
There can be many possible reasons for keys breaking or falling out:
To understand what this leads to and determine the probability self-repair, consider the following cases when one or more keys have fallen out or do not work:
- the upper part simply jumped out of the mounts, got stuck, the plastic mount broke, or the fixing lugs on the aluminum base of the keyboard were bent. - We install, repair or replace ourselves;
- there was a short circuit and/or destruction of the conductive paths due to a manufacturing defect, liquid ingress or other outside interference. - It is worth contacting the service if you do not have certain skills;
- damage to the connecting motherboard plume. - Replacement (preferably by a specialist) of the film or the entire device.
Taking into account the fact that the majority of users are amateurs, we will consider only the correction of breakdowns in the first case: mechanical damage.
To do this you may need:
- a regular needle or a syringe;
- paper clip;
- glue;
- knife, small screwdriver;
- wire cutters and pliers;
- thin soldering iron and lighter;
- small vice.
The first two positions of the list are enough to simply insert the dropped item, and the rest may be needed for minor repairs.
Important: Please note right away that all work must be carried out ONLY with the device disconnected from the network and the battery removed.

Button and its design
Before inserting a button into the laptop keyboard yourself, we recommend that you become familiar with its design. This will help you carry out repairs correctly, as well as make installation easy and simple. It should be remembered and taken into account that, unlike a stationary one, a laptop keyboard has a shorter stroke.
They consist of:
A typical keyboard base in a laptop is an aluminum plate, stamped with ears for good fixation of the clamshell and the contact pad, under which there are three layers of film with conductive graphite tracks.
Reliable fastening of the swing ensures uniform movement and the absence of distortions when pressing the key.
Please note that various manufacturers There may be slight design differences in the shape and types of fasteners.
Therefore, if you need to disassemble it yourself for the first time, proceed carefully.
Disassembly procedure
There are often situations when it becomes necessary to completely remove and disassemble the button. For example, sinking, lack of response on the screen when it is pressed, or deformation of the folding bed mounting ears. Removing, disassembling and inserting a button into a laptop keyboard is quite easy.
To do this, you will need a thin, flat instrument, such as a dental hook. As you know from the previous section, the swing is attached to the lid in four places. You can’t just bend it and “rip it off” - this will deform the swing and lead to damage.
That's why:
Inserting a button on a laptop is very easy
First, we carefully inspect all the fasteners, ears, antennae and grooves again. If you have carefully studied the device and design, read the disassembly procedure, then putting the popped element back in place will not be difficult.
This process involves two simple stages:
Please note that sometimes the lid will fall out along with the swing. In such a case, you should disassemble it, carry out an inspection, and only then install it. Moreover, first we insert the folding mechanism, and then the lid itself.
The described process may seem complicated, but you just have to try it once and you will see for yourself that inserting a button into a laptop keyboard is very simple!
Installing large buttons
Function keys (space, register, tab, enter, etc.) are larger than the others. It is this property that requires a slightly different order of installation. The reason for this is the presence of a metal stabilizer, which ensures even pressure.
There are additional lugs on the keyboard backing for reliable fixation of the rigidity amplifier itself.
And although everything else is exactly the same as described above, we install long buttons on the folding bed in three stages:
Please note that some long keys (for example, the spacebar) are fixed by two folding mechanisms and a rigidity amplifier.
We repair keys
As a rule, it is better not to start complex and time-consuming repairs yourself.
Having disassembled a faulty, poorly functioning or torn out key, you will have to, based on its careful examination, make one of three decisions:
- put it back “as is”, without changes;
- purchase and install a new one (used is also possible);
- make minor repairs or replace parts from the “donor” and continue operation.
For the last point, you may find the tools we talked about above useful.
Minor mechanical repairs include:
- assembly and installation of the popped-out parts of the mechanism into the grooves (quite often the clamshell “crumbles”);
- correction of bent lugs in the metal base of the keyboard (for example, when a heavy object falls on the keyboard);
- gluing cracks and broken fasteners.
It is not worth repairing the damage to the latches and hinge joint of the clamshell - it is better, if possible, to find a “donor” or replace the entire key. The smoothness, softness and quietness of its operation depends on this.
A rubber spring is usually glued to a film with conductive tracks. Sometimes it happens that it falls out. In this case, before inserting the button into the laptop keyboard, you should carefully install its wide part towards the bottom, strictly in the center. Displacement of the spring during installation is not allowed.
Having a problem with the keys? Try to solve it yourself if possible. It is not difficult! All you need is attentiveness, perseverance, accuracy and a little time.
Having acquired the necessary skills, you can, on occasion, save the life of your pet by promptly eliminating the consequences of moisture ingress or significantly extend it by performing a general cleaning of dust and crumbs.
Helpful advice: By the way, before completely disassembling the keyboard of your laptop, we strongly recommend taking a photo, just in case, of the order of the keys. This will help greatly simplify and speed up the reassembly process!
