How to open a wireless mouse Xiaomi: full analysis and repair

Xiaomi's modern periphery is famous for its minimalist design and ergonomics, but the lack of visible screws often baffles users when maintenance is needed. When a wireless mouse stops holding a charge or starts "doubling" a click, the only solution is to disassemble the device to replace the power supply or clean the contacts. Many owners mistakenly believe that the case is sealed dead, but engineers have devised ways to access the insides, hiding the mounts under decorative elements.

In this guide, we will take a closer look at the process of dismantling popular models such as the Mijia Mouse Lite and Silent Edition. You will learn where to look for hidden screws, what tools you will need to safely open and how to avoid damaging the plumes when halves are separated. Attention: any interference with the design of the device will automatically void the warranty, so proceed only if the warranty period has expired.

Before you pick up the tools, you need to determine the type of your mouse, because the designs can vary significantly. Some models have an integrated battery, others are powered by interchangeable AAA or AA batteries. Understanding the architecture of your device is the first step to successful repairs without fatal consequences for electronics.

Necessary tools for safe autopsy

To do this, you'll need the minimum toolkit that any home craftsman or radio enthusiast can have, and using inappropriate items like kitchen knives or thick screwdrivers can cause scratches on glossy plastic or damage to internal latches, thin blades and precision tools can be the key to the whole case.

• 🔧 Precision screwdrivers (cross-haired) PH000 or PH00, flat-footed 1.5 mm).
• 🎴 Plastic card, mediator or special spatula for opening (spudger).
• 🔦 Powerful flashlight or magnifier for inspection of hidden screws.
• 🧲 Magnetic mat or container for folding small screws.
• 🧤 Antistatic gloves (optional, but preferably for electronics protection).

Special attention should be paid to the mediator or plastic card. Metal tools can easily slip and damage the circuit board or leave deep furrows on the plastic. Soft plastic allows you to gently snap clips without leaving traces on the surface.

💡

Use a magnetic mat when disassembling small electronics - this will save you from losing tiny screws that tend to roll into the most inaccessible places.

Search for hidden fasteners

Xiaomi's design philosophy is that there are no visible screws on the front of the device, all the fasteners are carefully camouflaged under legs (glides) or decorative stickers. First of all, turn the mouse over and inspect the bottom carefully. In most cases, you'll see two large Teflon legs and one small round or oval sticker.

It is under this small sticker, often located closer to the front or in the center, that the main screw hides, holding the top and bottom covers together. In some models, such as the Xiaomi Wireless Mouse Silent Edition, there can be one screw, while in larger versions there can be two.

⚠️ Warning: When you unplug glides or stickers to access the screw, the Teflon layer may become damaged. Prepare spare legs for the mouse in advance, as the old ones will lose their sliding properties after removal.

Use a screwdriver of a strictly appropriate size to remove the screw. If the sting is too small, you risk licking the slits on the screw head, which will turn a simple repair into a difficult drilling task. After twisting the screw, do not rush to pull the halves of the body - there may be hidden latches around the perimeter.

Technology of disengagement of the body without damage

Once you remove all the visible screws, the most important step is to separate the upper and lower parts of the body, and the design is based on plastic latches that are located around the perimeter of the device, and do not try to push the halves with your fingers, applying force at one point, this is guaranteed to break the clips.

Take a plastic blade or a mediator and gently insert it into the junction between the top and bottom panels, start at the front, next to the buttons, or at the back, where the logo usually is, push the tool along the perimeter, sequentially snapping the locks, and you'll hear the characteristic clicks — that's a normal workflow.

When all the latches on the sides are freed, you can slightly lift the top cover, and it's important to exercise the utmost caution, because there may be a thin plume inside that connects the button board to the main module, and a sharp upward movement can break this conductor, after which recovery will require soldering.

Features of the design of different models Xiaomi

Xiaomi’s peripheral lineup is diverse, and each model has its own design nuances. Understanding these differences will help avoid errors when disassembling specific devices. Below is a comparative table of the main characteristics of popular models.

Models with built-in batteries are usually more difficult to maintain, as the battery can be soldered to the board or firmly planted in a plastic frame. In such cases, replacing the battery requires soldering iron skills and knowledge of basic electrical safety. Lithium-ion batteries are sensitive to punctures and overheating.

Simpler versions that run on finger batteries often have a modular design, where the board with the sensor and buttons is a single unit.This makes it easier to clean the optical sensor, which over time gets clogged with dust and pile, causing cursor problems.

Replacement of the battery and maintenance

The main reason that users open wireless mice is to replace the battery, and even if the battery compartment opens from the outside, the contacts can become oxidized and the spring loses their elasticity, and when you disassemble the case, you have full access to the contact group.

To clean the contacts, use a cotton swab dipped in isopropyl alcohol. Gently wipe the joints, removing the white oxide plaque. If the spring is stretched and the battery is dangling, causing intermittent power loss, it can be gently squeezed slightly or a small piece of foil can be inserted (with care not to cause short circuit) for better contact.

• 🔋 Remove the old battery and check the production date.
• 🧹 Blow the insides with compressed air to remove dust.
• 🧪 Wipe the contacts with alcohol solution.
• 🔍 Check the fee for bloated capacitors or detached tracks.

When you install a new battery, make sure you're polarizing. Although modern devices have anti-pole protection, don't take the risk. Once serviced, assemble the device in reverse order, tightly pressing the halves of the body until the characteristic snap of all latches.

⚠️ Warning: Never use water to clean electronics. Even distilled water may contain impurities or not dry in hard-to-reach areas, which will lead to corrosion of the board.

Assembly and performance check

The final step is assembly. Make sure all the plumes are tightly connected to the point. When you connect the halves of the body, first snap one side, then the opposite side, moving around the perimeter. Don't leave gaps between the parts, but don't squeeze the body too much.

After the screws are twisted, take your feet back in a hurry. First, check the performance of the mouse on the computer. If all the buttons are pressed clearly and the cursor moves smoothly, you can degrease the surface under the legs and glue new or old (if they are still sticky) into place.

💡

Quality assembly depends on the clips snap sequence: start with the area around the screws and move to the edges of the device.

For fixing decorative stickers or glides, it is better to use a special glue gel or bilateral tape for electronics (for example, 3M). Conventional superglue is not recommended, since its pairs can settle on an optical sensor or lens, which will worsen tracking.
