Xiaomi’s game manipulators, such as the Mi Gaming Mouse or the newer Xiaomi Wireless Mouse Lite, are known for their minimalist design and high performance. However, even reliable electronics require maintenance over time: double clicks, sticking buttons or cable problems are frequent companions of active gaming. Disassembly of the mouse allows you to conduct deep cleaning of the sensor, replace the mikriks or simply lubricate the wheel mechanism for silent operation.
The process of dismantling these devices has its own nuances related to the design of the case and the location of hidden screws. Unlike office models, gaming devices are often assembled using dense seats and hidden fasteners under decorative elements. A key feature of most models is the lack of visible screws on the bottom panel without removing Teflon legs or stickers. The correct approach to opening the case ensures the preservation of the warranty (if it is still relevant) and the integrity of plastic latches.
Before starting the procedure, you need to prepare the workplace and the appropriate tool. Haste or use of inappropriate items can lead to breakage of plastic mounts that are almost impossible to restore at home. In this article, we will examine in detail the stages of dismantling popular models, paying special attention to safety and design specifics.
Tools and workplace preparation required
You will need a minimal but specific set of tools to open the case safely and efficiently. Standard household screwdrivers may not be suitable because of the specific screw strands used by the manufacturer. The main tool will be a set of precision screwdrivers, including cross bits of size PH0 and PH00, as well as flat slits 1.5-2 mm wide.
Special attention should be paid to the tools for working with adhesives and Teflon coatings, many screws hidden under stickers or soft rubber legs, which when sloppy handling break, to remove and then install will require:
- 🔧 Thin metal scalpel or blade for careful cutting of glue.
- 🌡️ Hair dryer (construction or household) for softening the adhesive layer under stickers.
- 💳 Plastic card or mediator for smearing the case without scratches.
- 🧲 Magnetic tray or small screw sorting container.
Workspace management is critical, and small screws and springs can scatter across the table and fall to the floor, which can stop repairs indefinitely, and it is recommended to use an antistatic mat and good lighting to see the condition of the plumes and contacts.

Use a magnetic screwdriver stand or spread the screws on a piece of paper by signing the dismantling steps with a marker - this will save time when assembled.
Design analysis and search for hidden fasteners
The first step in the process of disassembling the Xiaomi Gaming Mouse is a thorough visual inspection of the bottom panel. Manufacturers often mask the mounting points to preserve the aesthetic integrity of the device. In most models, the main screw is under a central sticker with a logo or specifications.
Carefully heat the dryer sticker for 10 to 15 seconds without overheating the plastic, and slowly remove it with a thin blade, which often hides a screw holding the center of the body. Also check the Teflon legs (glides): sometimes additional fasteners are hidden under the front or back pair of legs. If the legs are reusable, they can be removed and glued again, otherwise you will need to replace them with new ones.
⚠️ Warning: When heating the sticker, do not hold the hair dryer too close to the plastic for more than 20 seconds, otherwise the top mouse cover may warp or change color.
Once all visible plugs and screws have been removed, the body can still be held on the latches, which are located around the perimeter of the device and require careful opening. Don't try to tear the halves of the body by force, you'd better walk along the seam with a plastic map or a thin spatula, hearing the characteristic clicks of the locks opening.
The process of opening the case and dismantling the board
When all the screws are twisted, the most critical thing is to separate the top and bottom of the body, insert the plastic card between the halves in the area of the wheel or tail of the mouse, move along the perimeter, gradually snapping the locks, operate smoothly, without jerking, so as not to damage the thin plastic walls.
When you remove the top cover, you'll see the interior layout, the board is fixed to the bottom of the case or on a special frame. Pay attention to the connection to the scrolling wheel: in some models, it can be fixed with a separate screw or plastic holder. Before fully removing the board, make sure that nothing interferes with its movement.
Removing the circuit board may require disconnecting the plume if present (in wireless or modular design models).In wired versions, the cable is usually soldered directly to the board, so be careful when raising the fee so as not to damage the soldering site or the wire itself.
☑️ Autopsy procedures
It is important to note that in some versions of the Xiaomi Mouse Lite, the board can be additionally secured with screws to the bottom bowl. Check for such mounts at the corners of the board and in the center. Use an antistatic bracelet or periodically touch a grounded metal object to relieve static stress before touching electronic components.
Replacement of switches and maintenance of mechanics
The main reason for disassembling game mice is often a malfunction of the switches (micrics). Double click or lack of reaction to press is treated with a replacement component. This will require a soldering iron with a thin sting, solder and, preferably, suction of solder or braid.
Standard switches are labeled D2FC-F-7N or similar, but Xiaomi gaming models can use enhanced versions with a resource of up to 20 or 50 million taps. Before soldering a new element, it is recommended to lubricate the wheel mechanism and buttons with a special thick lubricant (for example, based on lithium or Teflon) to eliminate the creaks.
| Component | Type of malfunction | Repair method | The necessary tool |
|---|---|---|---|
| Left/Right button | Double click, sticky. | Replacement of mikrik (Omron, Huano) | Smear iron, sweat, suction. |
| Kolesico | Scrolling failures, backlash | Encoder replacement, lubrication | Smear iron, thick lubricant |
| Side buttons | Lack of response | Replacement of clock button | Smearing iron, tweezers |
| Cable | Signal loss | Replacement of wire, soldering | A soldering iron, a new cable. |
When installing new switches, it is important not to overheat the board. Keep the soldering iron stinger on the contact for no more than 3-4 seconds. If you do not have soldering skills, you can try to carefully disassemble the old mikrik and clean the contacts inside, but this is a temporary solution.
Where to buy the original switches?
Cleaning the sensor and optics care
An optical or laser sensor is the eye of your mouse, and dust, villi, or hair that enters the sensor can cause erratic behavior or complete loss of tracking, and cleaning this area should be done with the utmost care.
Use a dry soft brush or compressed air to remove large dust particles. To remove fat spots or persistent contaminants, you can use a cotton swab slightly soaked in isopropyl alcohol. Isopropyl alcohol evaporates quickly and leaves no conductive traces, making it an ideal cleaning agent for electronics.
⚠️ Warning: Never use water or aggressive solvents (acetone, gasoline) to clean the sensor lens, this can lead to clouded optics or damage to plastic elements.
Also check the condition of the lens for scratches, deep scratches can scatter light and make tracking worse, in which case the entire bottom panel or dongle may need to be replaced if the design is modular.
Device assembly and function testing
The assembly is done in reverse order, but requires increased attention to detail. Make sure that all plumes and cables are packed into their channels and not clamped by the body. Incorrectly stacking the cable can damage it when screws are tightened or foreign sounds appear when clicks.
Twisting the screws cross-cross, gradually increasing the force to ensure that the parts of the case fit evenly. Do not drag the screws, especially if they are screwed into plastic, this can lead to cracks around the screw cap. Teflon legs, if they were removed, need to be degreased with alcohol and tightly glued, removing the air bubbles.
Once assembled, connect your mouse to your computer and check all the features: basic clicks, side buttons, wheel scrolling and backlighting (if any). Use online services to check double clicks and positioning accuracy. If everything works correctly, you can consider the repairs successfully completed.
💡
Quality assembly depends on the correct stacking of wires and the absence of distortions of the body before the final tightening of the screws.
