The modern periphery from Chinese giant Xiaomi is famous for its minimalist design and high ergonomics, but even the most reliable devices require maintenance over time. Users often face the need to disassemble a mouse to clean up dust, replace a worn-out wheel or restore the operation of a button. Unlike the standard office periphery, models from Xiaomi, such as the Mi Silent Mouse or Xiaomi Wireless Mouse 2, have a hidden design without visible screws.
The need to open the case can arise suddenly: no click has responded, the sensor is lost or just requires a banal cleaning of contamination. It is important to understand that any interference with the device body cancels the warranty, so before starting work, you should weigh the risks. If the device is warranty, it is better to contact an authorized service center, but if this option is excluded, then a careful self-disassembly is the only solution.
In this article, we will take a detailed look at the algorithm for safely opening different models of Xiaomi manipulators. You will learn where to look for hidden screws, how to properly snap plastic latches and what tools you will need to work with delicate electronics. The main rule is not to use force where patience is required, since the plastic of the case can be quite fragile.
Before you start any manipulation, be sure to prepare the workplace. You will need good lighting to see fine details, and an antistatic mat or just a clean dry surface. Remember that there are electronic components inside that are sensitive to static electricity, so it is recommended to touch the grounded metal object before touching the board.
Necessary tools for disassembly
The quality of the work is directly dependent on the toolkit used. To open compact devices like Xiaomi Portable Mouse will not fit rough screwdrivers that can tear off the slats or damage plastic. You will need a set of precision tools designed to work with small electronics and smartphones.
The main tool will be a PH00 or PH000 sized cross screwdriver, which is the size used in the board attachment screws inside the case, a plastic blade (spooder) or a mediator will also be an indispensable assistant, and metal tools are best avoided for opening latches, as they leave scratches and can damage the contact areas on the board if you move carelessly.
In addition, prepare tweezers with curved ends to extract small screws and work with plumes. If you plan to clean the sensor or contacts, you will not be superfluous canister of compressed air and isopropyl alcohol. For fixing small parts, it is convenient to use a magnetic mat or simply a container with compartments, so as not to lose microscopic screws.
☑️ Preparation for disassembly
Search for hidden fasteners
The biggest challenge in disassembling Xiaomi's technology is that there are no visible screws on the outer surface of the case. The company's engineers strive for the highest aesthetics, by hiding all the fasteners under the decorative elements. The first thing you need to do is turn the mouse over and carefully examine the bottom panel.
In most models, including the Mi Wireless Mouse, the screws are hidden under Teflon stickers or rubber legs. Carefully probe each leg: if it feels a groove or screw cap, then the mount is there. To access them, you need to gently tuck the sticker edge with a thin needle or blade.
What do we do with the spoiled glides?
Sometimes the screws can be hidden under the logo or in the battery compartment. In some versions, the fastener screw is directly under the battery or battery. Be sure to remove the power source before you start unscrewing to avoid short circuit. After removing all visible screws, the case can still be held on the latches.
⚠️ Warning: Pluted Teflon stickers often break when removed. Make sure you buy new glides or adhesive base in advance, otherwise the mouse will not slide well on the surface after assembly.
The process of opening the case and charging
Once all the screws are twisted, the most critical step is to separate the top and bottom of the body. Don't just try to tear the halves with your hands, because there are thin plastic latches inside that are easy to break. The movements must be progressive and accurate.
Insert a plastic blade at the junction between the top and bottom of the body, starting at the front (near the buttons) or at the back where there are no screws. Slowly guide the tool around the perimeter, hearing the characteristic clicks of snapping locks. If the resistance is too high, check if you missed any hidden screw under the stickers.
When the body is divided, don't make sudden movements. The board can be connected to the top of the case through a button plume or an LED indicator. In models with backlights or additional buttons, there is often a thin wired plume that is easy to break when you carelessly jerk. First, disconnect all connectors from the motherboard.
💡
Warm up the lower part of the body with a hair dryer at a minimum temperature for 30-40 seconds. The plastic will become softer, and the latches will snap more easily, reducing the risk of breakage of the fasteners.
To turn off the plume, gently lift the connector's locking tongue up (if it's pressed) or simply pull the connector out if it's pin-to-pin. After that, you can fully remove the board from the bottom of the case for repairs or deep cleaning.
Cleaning the sensor and maintenance of the wheel
One of the common causes of cursor instability is contamination of the optical sensor. Dust, wool or fine pile, when you get on the lens, interfere with the reading of the surface. To clean, use a cotton swab lightly soaked in isopropyl alcohol, and gently wipe the glass lens of the sensor.
The scroll wheel problem is solved by cleaning the encoder, and over time, dirt gets inside the encoder, causing chaotic page scrolling or sticking, disassemble the encoder mechanism if possible, or blow it with compressed air, and in some cases, a drop of special electronics lubricant helps, but you need to apply it in a microscopic amount.
Also check the status of the button contact areas. If the mouse stops clicking or starts double clicking, it may be that the contacts under the membrane or mechanical switch have oxidized. Wipe the contacts with alcohol. If the problem is mechanical wear of the microswitch, it can be replaced by having the skills to work with a soldering iron and soldering off the old one by setting a new similar size.
| Mouse model | Location of screws | Type of connection of the payment | Difficulty in parsing |
|---|---|---|---|
| Mi Silent Mouse | Under the stickers (4 pcs) | plume + connector | Medium |
| Xiaomi Wireless Mouse 2 | Inside the battery bay | Direct connection | Low. |
| Mi Portable Mouse | Under the Glides (2 pcs) | schleife | Tall. |
| Xiaomi Gaming Mouse | Combined | Lots of plumes. | Tall. |
⚠️ Warning: When cleaning the sensor, do not use acetone or aggressive solvents, they can cloud the plastic lens, which will make the sensor inoperable.
Assembly of the device and check of performance
After successfully performing all repair or cleaning manipulations, you need to assemble the device in reverse order. Make sure that all plumes are connected before clicking and fixed. The board must lie tightly in place, without dangling inside the case, otherwise there may be closures or poor contact of the buttons.
As you connect the halves of the body, first snap the central locks, then walk around the perimeter, gently pressing your fingers to a characteristic sound. Don't use a hammer or heavy objects to press - only uniform pressure with your hands. After that, twist all the screws, but don't pull them over so as not to damage the plastic thread.
The final step is to stick new glides or fix old ones, insert a power source and check all the functions: cursor movement, wheel scrolling and button pressing. If everything works correctly, the process can be considered complete. In case of problems, you may need to re-diagnose and check connections.
💡
Quality assembly depends on the purity of the joints of the body: remove all dust and villi before the final connection of the halves, otherwise backlashes or creaks will appear.
