How to disassemble the Xiaomi Mi Mouse: an expert guide

The modern periphery of Chinese tech giants often delights users with stylish design and ergonomics, but sometimes requires intervention for maintenance or repair. The Xiaomi Mi Mouse disassembly is a process that can be required when sticking buttons, contaminating the sensor, or wanting to replace the battery with a more capacious counterpart. Despite its minimalist appearance, there is a thoughtful engineering design inside the device that requires careful approach.

Owners often find that there are no visible screws on the body, which is confusing. Xiaomi Mi Wireless Mouse (like its wired version of Silent Edition) is designed to keep the monolithic, so the main fasteners are carefully hidden from view. The key is the understanding that the top cover is not a removable part in the usual sense, but requires careful detachment from the main body.

Before you start physical impact, you need to prepare a good lighting workplace and make sure you have the right tool. Careless handling of plastic can cause chips or break latches, so there's no rush here. In this article, we'll go into detail each step of dismantling so you can safely maintain your device.

Tools and workplace preparation required

To do this successfully, you will need a minimal but specific set of tools. A standard cross screwdriver may not be suitable, as the screws in modern gadgets often have a custom hat or are too small for a household tool. The main tool will be a thin cross screwdriver (usually the size of a PH0 or PH00) and a set of plastic mediators or shoulder blades.

Special attention should be paid to the cleanliness of the surface on which the disassembly will be performed. Small screws are easily lost, and dust inside the case can settle on the board and cause a short circuit in the future.

Also, prepare a wide-throat container to fold screws so they don't roll around the table. If you're planning to clean contacts, stock up on isopropyl alcohol and cotton swabs in advance.

• 🛠️ A set of precision screwdrivers (cross-haul) PH00, PH0)
• 🔧 Plastic blade or mediator for opening the body
• 🧹 Tweezers with thin curved ends for extracting small details
• 🧴 Isopropyl alcohol and lilac-free wipes for cleaning

⚠️ Attention: Using metal tools (knives, screwdrivers) to tweak plastic parts of the case can leave deep scratches or crack plastic. Always use plastic blades where possible.

Design analysis and search for hidden fasteners

The first step before disassembling the Xiaomi Mi Mouse is to look at its exterior, and many users mistakenly assume that if there are no screws on the bottom, there are none anywhere, but the Mi Mouse design implies that the main screws are hidden under decorative elements or sliding legs.

Turn the device over and look at the bottom panel, and you'll see two large sliding legs (Teflon stands) and maybe small stickers with a serial number, and it's under one of these areas that the mounting elements are most often hidden. In some versions, the screws may be under the top decorative panel, but in the classic model, they are traditionally located at the bottom.

It's important to understand the difference between the modifications: the wired version of the Silent Edition and the wireless version can have minor differences in the location of the latches. Carefully swipe your finger along the edges of the junction of the upper and lower covers - if you feel a gap or see screws, the task is simplified. If there are no screws, then the body is held on the latches.

Don't try to force the body parts out without making sure there are no hidden screws. The ABS plastic used in manufacturing is strong enough, but fragile when bending. A sharp force can break the internal guides, and then it will be impossible to assemble the device back without gaps.

The process of dismantling the body: step-by-step instructions

We're going to start disassembling the screws directly, and if you find them under the sliding legs, you need to gently tuck them in with a thin blade or needle and remove them, and underneath them, you're going to open holes with screws that you need to unscrew, and if you don't have screws, you're going to go to opening the hull through the latches.

Insert a plastic blade at the junction between the top and bottom of the body, starting at the front (near the scroll wheel). Carefully press and swipe the tool along the side face, listening to the characteristic clicks of the opening latches. Do not dive the tool deep, so as not to damage the plumes or board located close to the edges.

Once the perimeter has been passed and all the latches are freed, you can gently lift the top cover, and do this slowly, because there may be wires or button plumes to the top if the design implies that they are in that half.

⚠️ Warning: When splitting the halves of the case, make sure you do not damage the plume connecting the buttons to the main board.A sharp jerk can lead to irreversible rupture of contacts.

Working with internal electronics and sensor

When you remove the lid, you'll see the Xiaomi Mi Mouse's internal device, and the central circuit board is a soldered circuit board, microcontroller and optical sensor, and if the purpose of the disassembly was to clean, that's where you need to focus your attention.

The optical sensor is the eye of a mouse, and even a microscopic speck of dust or hair can cause erratic behavior. Use a dry cotton swab or a slightly soaked cotton swab to clean. Movements should be soft, without strong pressure on the sensor lens.

Also check the status of the button contacts. Over time, they can oxidize, which leads to double clicking or no reaction. Graphite spray on the contacts wears off over time, in which case it may be necessary to replace the microswitches (switches), which requires soldering skills.

• 👁️ Cleaning the lens of the optical sensor from dust
• 🔌 Checking the density of the plumes and connectors
• 🧼 Degreasing the contacts of buttons with alcohol
• 🔋 Inspection of the battery compartment for oxidation

If you plan to modify the device, such as installing a different format battery, make sure the voltages match.Standard Xiaomi Mi Mouse often run on a single AA or AAA battery, and changing the power circuitry can bring the controller down.

💡

When assembled, apply a minimum amount of lubricant (such as lithium) to the axis of the scroll wheel, which will make the scroll more smooth and silent, returning the tactile sensation of the new device.

Assembly of the device and verification of functionality

The assembly is done in reverse order, but requires more care, first you need to make sure that all the internal components are in place and nothing prevents the closure of the housing, the plumes must be placed in special slots so that they do not get pinched.

So you can combine the halves of the body and start snapping them around the perimeter, moving from center to edge. A characteristic click will confirm that the lock is in place. Don't put too much effort: if something doesn't fit, it means that the part is incorrect or the screw/wire is interfering.

After the parts of the body are joined, screw the screws (if they have been removed) and return the sliding legs to place. If the legs have lost stickiness, you can use double-sided tape or a drop of glue, but try not to overdo it so that the glue does not get inside the mechanism.

The final step is to test the performance, connect the receiver or cable, set the cursor on a flat surface (preferably on the mat), and check:

1. Accuracy of cursor positioning.
2. Responsiveness of left and right buttons.
3. The smoothness of the scroll wheel.
4. Stability of the connection (no breaks).

⚠️ Warning: If the mouse is not working properly after assembly, don't rush to disassemble it again immediately. Try replacing the battery or reconnecting it. USB-Sometimes it takes time for the system to recalibrate the sensor.

💡

The basic principle of assembly is that you don't have to work too hard, and if you don't connect easily, you've broken the sequence or made a mistake in the previous step.

Frequent problems after disassembly and their solution

Even skilled craftsmen can find it difficult to intervene in a device, and one of the common problems is that the squeaking of the case occurs when the latches are not firmly fixed or damaged when they are opened, and the solution is to glue the joints with a thin strip of paint tape from the inside.

Another common problem is double-click, and if you've had a problem after cleaning your contacts, you've run out of microswitch life, and if you've had a switch that's replaced with a new one, like Omron or Huano, which are often used as donors.

There can also be a loss of sensor sensitivity, which is often the case when you put a finger on the lens and you have fat marks, and then you clean the optics again carefully and usually you solve the problem.

In conclusion, it should be noted that disassembly Xiaomi Mi Mouse is an affordable procedure that allows you to extend the life of your favorite gadget. The main thing is to act methodically, use the right tool and not ignore the small details of the design.
