A computer mouse is an integral part of any desktop PC, but it is also used with laptops. After all, many users prefer its touch panel, which is available on similar models. This is due to the extreme usability of the mouse and intuitive functionality.
A huge number of models are presented on the modern market and every year more and more new, more advanced ones appear. But their price is also changing. What should I do if the old mouse is broken, but I don’t want to buy a new one due to financial or any other considerations? How to do an independent repair or even make a new mouse yourself? You will learn about all this in this article.
Common computer mouse problems
To begin, consider the possible problems in the operation of the mouse, which owners of this device often have to face. Not only the choice of the type of repair, but also the final result will depend on how correctly you determine the cause of the problem.
IMPORTANT! Carry out a thorough inspection of the device to make sure that the damage is present exactly in the part where you think. If you carry out the wrong repair, you can not only not achieve any result, but also break the mouse completely. That is why it is also important to study the sequence of all actions in advance.
There are several main types of breakdowns, which in most cases are found in ordinary users of office mice. Eliminating them is not so difficult, so even a beginner who does not have special skills and knowledge in the field of technology will cope with the task if he spends a little time and effort.
The cause of the problem may be:
- cable break
- button breakage;
- wheel breakage.
You can try to disassemble the mouse and carry out repairs yourself. But for this it is important to understand the internal structure and the principle of the mouse. All the necessary information is easy to find on the Internet, so you should not worry about a lack of knowledge.
How to repair a mouse for a computer
Each of the above reasons requires special repair. But in any case, the mouse will have to be disassembled. How to do it right?
How to disassemble a mouse
In order to access the internal device of the mouse, it is necessary to unscrew the fixing screws, which are located on the bottom side. In most cases, this is a single screw.
Sometimes it can be difficult to find it - manufacturers can seal the screws with stickers or thrust bearings. Feel the entire surface - in place of the screw there will certainly be a deflection in the shape of a circle.
If everything is simple in the case of the sticker, then removing the thrust bearings can be very difficult. You will need a knife to carefully remove the part, which must be returned later - without the thrust bearings, the device will move on the surface much worse.
After that, you need to disconnect the mouse and remove the upper part with buttons. Then take out the board. On some models, it can be screwed on.
IMPORTANT! Try not to touch the optical parts with your hands - if traces remain on them, you must carefully wipe them. Otherwise, the mouse may work worse than before.
Wire repair
Most often, a break occurs at the base due to the fact that the mouse constantly moves on the surface. Repair is simple: you need to find the place of the cliff and with the help of wire cutters "bite off" the cable a few centimeters above and below this place. After this, the parts need to be soldered.
Do not forget to insulate them with tape or tape. A heat shrink tube is also suitable. Now you need to strengthen the cable - for this, use glue and glue the wire either to the case or to the mouse board.
Wheel troubleshooting
If, when scrolling through the page, the image jumps up and down, it is necessary to open the encoder. After that, remove dust particles from the contacts, clean them thoroughly and assemble the part again.
In another case, you may need to tighten the mount.
If the wheel axle is damaged mechanically, then you need to insert a new one. As a material, you can use either a hex key or a self-tapping screw of the desired size. The material must be turned and inserted into the device instead of the old axis.
Button Repair
First of all, pay attention to the "symptoms" of the malfunction. If the button returns to its previous state for a long time after pressing, there is a rattle, or it is difficult to press, the cause may be a simple contamination of the plate. It is only necessary to clean the parts. You can do this with an old toothbrush or cotton swab. It is best to use alcohol.
If the button does not always work, then it is necessary to disassemble the device and inspect the contacts. Most likely, soldering of each of them will be required. There may be a crack in the place of the problem button.
When the button does not press at all or does not return to its previous position, you need to replace it. Another one can be purchased at any specialized store. But if you don’t want to do this for financial or any other reasons, try swapping the broken button and the one you don’t use - for example, rarely does someone click on the button in the middle.
How to make a do-it-yourself mouse for PC
If you have an old mouse case and several improvised tools, you can assemble it yourself.
As a wheel, use any gear that will scroll. You also need to find the details that will be used as buttons. These parts must be connected to each other using a piece of copper wire.
Then find two pneumatic cylinders that will fall on the rest of the body. Place a metal plate on top - it can be removed from the watch. Cylinders must be soldered. The next step will be the implementation of a durable lower case.
IMPORTANT! Never remove the optics from the bottom. Without it, the mouse cannot work.
Now you know how to independently repair a computer mouse and how to disassemble it. In addition, now you have information on how to make a device yourself based on the old one. Thus, you can significantly save on the purchase of a new mouse and use a computer with comfort.
