Xiaomi’s Dual Mode Wireless Mouse Silent Edition has become a popular choice among users thanks to its quiet operation, versatility (Bluetooth and 2.4GHz support) and ergonomic design. However, even such a reliable device can require disassembly — whether it’s replacing the battery, cleaning contacts or repairing buttons. The main problem faced by owners is that the mouse body is fastened with hidden latches, and if unguarded, it is easy to break plastic locks or damage the top cover.
In this article, you will find detailed disassembly instructions tailored to the features of the Silent Edition, including the location of the latches, the necessary tools and typical errors, and we will also discuss when disassembly is justified and when to contact a service center, for example, when you have problems with a sensor or chips, if you are planning to clean or replace the batteries, our tips will help to avoid common damage.
When you need to disassemble Xiaomi Dual Mode Silent Mouse
Before you start the screwdriver, see if you really need to disassemble the body. In most cases, the mouse problems are solved without opening.
- 🔋 Mouse not turned on – check the battery (or battery in the version with) USB-C), Try to reset the connection in the settings Bluetooth/receiver.
- 🖱️ Buttons stick or don’t work – often the cause is contamination of contacts, but sometimes it helps to purge compressed air without disassembling.
- 📶 Connection problems – restart the receiver (take out and paste back into the USB-port, update drivers on PC.
- 🔊 Extraneous click sounds – in Silent Edition this may indicate wear on the button mechanism, but sometimes the noise disappears after cleaning.
Disassembly is justified in the following cases:
- 🔧 Battery replacement AAA (non-version USB-C) battery.
- 🧹 Deep cleaning of dust that gets under buttons or into an optical sensor.
- 🛠️ Repair or replace button microswitches (if they are completely out of order).
- 🔄 Replacement of 2.4 GHz receiver (if lost or damaged).
⚠️ Note: If the mouse is warranty, disassembly of the case will cancel it. In case of hardware malfunctions (for example, the sensor or Bluetooth module does not work), contact the authorized Xiaomi service center.
Disassembly tools: what you will need
For a tidy opening of the Xiaomi Dual Mode Silent Mouse, prepare the following set of tools:
| Tool. | Appointment | The alternative |
|---|---|---|
| Plastic spatula (mediator) | Unscratched separation of the shell latches | Guitar Mediator or Credit Card |
| Thin screwdriver PH00 or T4 | Spinning screws (if any) | A knife with a thin blade (caution!) |
| Tweezers | Extraction of small parts (springs, contacts) | Manicure pinch |
| Compressed air (cylinder) | Cleaning of dust from hard-to-reach places | Soft brush. |
| Tape or paint scotch | Marking of position of parts during assembly | Sticker or marker |
Important: Don't use metal screwdrivers to unplug latches, they leave scratches and can break plastic locks. If you don't have a plastic blade on hand, wrap the tip of the metal screwdriver with a tape.
How to Open the Case of Xiaomi Dual Mode Silent Mouse
The disassembly process consists of several steps. Follow the instructions carefully so as not to damage the latches.
Make sure the mouse is off (switch in OFF position)
Remove the battery (if any)
Prepare the workplace (soft surface, good lighting)

Step 1: Removal of the upper cover
The case of Xiaomi Dual Mode Silent Mouse is fastened by 6-8 plastic latches located around the perimeter. Start from the widest side (where the scroll wheel is located):
- Insert a plastic blade into the gap between the upper and lower part of the body at the scroll wheel.
- Carefully press to disconnect the first latch, and you'll hear a slight click.
- Move along the edge, alternately snapping the locks. Don't try to pull the lid off right away, it'll break the plastic!
- Leave the last latch opposite the wheel - it will snap itself when you lift the lid.
Critical detail: In the Silent Edition, the latch near the power button (under the Xiaomi logo) is particularly fragile. Start disassembling from the opposite side!
Step 2: Removing the printed circuit board
When you take off the top cover, you'll see a circuit board with buttons and a sensor to remove it.
- Disconnect the plume of the scroll wheel (gently tuck it into the shoulder blade).
- If there are screws in the mouse (in some revisions they are hidden under stickers), unscrew them.
- Raise the toll over the edges, don't pull the wires!
In the Bluetooth+2.4GHz version, the board will have two communication modules on it. Don't touch them with metal objects, which can cause static electricity and damage the chips.

Step 3: Assembly of the mouse after disassembly
When assembled, follow the reverse order:
- Put the charge in place, connect the wheel plume.
- Then, put the slacks on (if they were).
- Wear the top cover starting from the side of the scroll wheel.
- Close the latches, evenly pressing the cover until clicks.
Check the mouse before it's finalized, plug it in, make sure all the buttons and wheels are working, and if something's not working, check the plumes' contacts.
💡
Before assembly, wipe the contacts of the battery compartment with alcohol - this will improve the connection and prolong the life of the batteries.
Common Mistakes in Disassembly and How to Avoid Them
Even experienced users sometimes make mistakes that lead to mouse failure.
- 🔨 Using metal tools -- scratches the body and breaks the latches. Always wrap the screwdriver with tape or use a plastic blade.
- 💥 Sharp lids, which cause cracks in the plastic, and you have to snap them one at a time, without jerking.
- 🔌 Unlocking the plumes without fixing, you can break the contacts. Remember or take a picture of how they were connected.
- 🧲 Touching chips with your bare hands - static electricity can disable a Bluetooth module.Use an antistatic bracelet or touch metal parts of the case before work.
Another common problem is the loss of small parts (springs, rubber gaskets), to avoid this, work on a light surface (for example, a white sheet of paper) and use a magnetic substrate for screws.
⚠️ Warning: If the scroll wheel is not working properly after assembly (scrolling in jerks or not fixed), check if dust has hit the optical sensor of the wheel. Clean it with compressed air or a soft brush.
Cleaning and maintenance after disassembly
Once you've disassembled the mouse, you should do a preventive cleaning, which will prolong its life and improve the function of the buttons.
- 🧹 Dust removal - use a can of compressed air or a soft brush. Don't blow with your mouth - moisture from breathing can oxidize contacts.
- 🧴 Clean buttons – if the buttons stick, apply 1-2 drops of isopropyl alcohol (90%+) on a cotton swab and wipe the contacts of the micro-switches.
- 🔦 Optical sensor check: remove dirt from the sensor lens (at the bottom of the mouse.
- 🔋 Battery compartment contacts - clean with a swallow or alcohol from oxidation.
If the mouse buttons become less responsive, the reason may be wear of rubber caps under micro-switches, which can be replaced with new ones (sold in mouse kits) or temporarily "resuscitated" by dripping silicone lubricant.
💡
Regular cleaning of the mouse (every 3-6 months) prevents sticking buttons and prolongs the life of micro-switches.
When the disassembly will not help: hardware malfunctions
Not all problems with Xiaomi Dual Mode Silent Mouse are solved by disassembly.
- 📡 Bluetooth or 2.4 GHz doesn't work -- if the mouse isn't detected on any device, the problem could be a damaged communication module.
- 🖱️ The sensor doesn't track movement -- if cleaning the lens didn't help, maybe the optical chip failed.
- 🔋 The mouse does not hold a charge (in the battery version) – the cause may be a bloated battery or a faulty power controller.
- 🔊 Constant click noise — in Silent Edition, this often indicates mechanical wear on micro-switches. Replacing them requires precise soldering.
If you are not sure about the cause of the malfunction, make a diagnosis:
- Connect the mouse to another device (PC, laptop, tablet).
- Try resetting Bluetooth settings on the main device.
- Check the mouse with another 2.4GHz receiver (if there is a spare one).
The cost of repairs in the service is usually 30-50% of the price of a new mouse, and if the device is older than 2-3 years, it is more advisable to consider buying a new model.
