There are many problems when buttons fall out or stop working. There are many causes of breakdowns. To carry out repairs, you should familiarize yourself with the structure of the keys.
Reasons for the button to fall out or replace
With frequent use of the device, some buttons may break. But not in all cases, you need to immediately contact a service center. You can do all the work yourself, saving money and time.
Among the causes of the problems are the following:
- Liquid got into their honey.
- You put a lot of effort when pressed.
- The keyboard has fallen.
- If you use a vacuum cleaner for cleaning by turning on a lot of power.

Keyboard Button Design
Before self-repair, you should familiarize yourself with the design. It is important to know what to do next.
Note! The buttons on the standard computer and laptop are different.
The keys consist of the following parts:
- A cover with a lock (this is the button itself, which is pressed). It is made of plastic. Grooves and latches are installed on the inside. And if it is large (for example, Enter or a space), inside there is also a metal-based stiffness stabilizer.
- X-shaped device and latches. He holds the button. Fastenings are carried out in two places. The X-shaped mechanism is not present in all versions of the device (most often, it is absent in keyboards for personal computers).
- Spring element that raises or lowers it. It is also capable of shorting electrical contacts. The spring is a small rubber cone. When you click on it, the function will work even if the key is missing.
As the basis of the device using an aluminum plate. A vyshtampovka is installed on it (fixes a folding bed) and a platform with contacts. Under the last is the film through which current flows.
Attention! Depending on the model, the details of the keyboard may vary slightly.

- Needle.
- Clip.

How to put a button: step by step
If you just need to return the dropped key, the process does not take much time and effort. Elements often pop up from the mounts, this does not mean that something is broken. Another question, if the same button constantly pops up, then the mounts are damaged. To correctly return it to its place, do the following:
- We put the mechanism on the panel. Press a little on the ears of the latter to fix the part.
- Now we apply the button to the device and press. We should hear a click similar to when we press keys. Using a paper clip, you can fix the position.
- If the button fell out with an X-shaped mechanism, you must first disassemble it. We do an audit. Now install. You need to start with the mechanism, end with the button.
But if the key is large (space, Enter), the installation process will be slightly different. A metal stabilizer appears. He is responsible for uniformly pressing. If you do not take it into account, pressing the key will not be comfortable.
We do the following:
- Install the stabilizer.
- We fix it. We start fastening in the grooves on the case.
- Now we insert the stiffener into special ears. This will ensure a secure fit.
- The button also has special ears in which it is necessary to put a stabilizer.
- After inserting the stiffener, you can return it to its place.
It’s very simple to just return the dropped key to its place. But if the keys break, you should contact the service center.
