Xiaomi Mi Notebook Pro series laptops have earned a reputation for stylish and productive devices, but their maintenance requires a special approach. Owners often face the need to upgrade the drive or clean the cooling system from dust, which inevitably accumulates over time. Disassembling this ultrabook is a delicate process where every step must be done with maximum accuracy, so as not to damage fragile plumes or the case.
Before you start dismantling, it is important to understand that self-disassembly can lead to loss of warranty if the screws remain traces of opening. However, if the warranty period has expired or the device is purchased without official support in your area, competent maintenance will prolong the life of the equipment. In this article, we will discuss in detail the process of removing the bottom cover, disconnecting the battery and replacing components.
You need not only a set of tools, but also a quiet environment where no one will disturb at the most critical moment. The Mi Notebook Pro 15.6 has a unique design of screws under the lid, hidden by a decorative pad, and ignoring this fact can damage the body when you try to remove the panel by force.
Tools and workplace preparation required
You will need a specialized set to work with the Xiaomi Mi Notebook Pro, as standard cross screwdrivers may not be suitable for some screws or damage their hats. Preparation takes no more than 10 minutes, but significantly reduces the risks.
First of all, make sure that the laptop is completely off, not in sleep mode. Unplug the charger and all peripheral cables. The work surface should be clean, dry and well-lit. It is recommended to use an antistatic mat or at least non-synthetic fabric.
To successfully complete all operations, prepare the following list of tools:
- 🛠️ Precision screwdriver set (PH0, PH00) hull-rotor.
- 🧤 Plastic blade or mediator for opening latches.
- 🧲 Magnetic tray or sheet of paper with markup for sorting screws.
- 💨 A compressed air container for primary dust cleaning.
Importantly, the use of metal tools to tamper with the case is strongly discouraged: the aluminum alloy that the Mi Notebook Pro is made of easily scratches, and careless movement can lead to a short circuit on the board if it accidentally hits the contacts.
⚠️ Before starting any work, be sure to discharge static electricity by touching a grounded metal object, for example, a heating battery or a PC system unit body.
The process of removing the bottom cover of the laptop
The first stage of dismantling Xiaomi Mi Notebook Pro seems simple, but contains important nuances. Turn your laptop and carefully examine the bottom panel. You will see a number of screws, but their number and location can confuse the beginner.
In some versions, two screws can be hidden under rubber legs or decorative plugs. In the Mi Notebook Pro 15, you often find the screws under a long sticker with information about the device. Carefully heat the sticker with a hairdryer at a minimum temperature to remove it without damage if there is a fastener underneath.
Turn all the visible screws counterclockwise. Fold them in the prepared tray in the order in which you twisted them, which will help avoid confusion, because the screws can vary in length even within the same lid.
Once you remove the entire mount, don't try to remove the lid right away. It's held on plastic latches around the perimeter. Take a plastic blade and walk gently between the top and bottom of the mount. Move from the corners to the center, gradually snapping the locks.
So, don't be fanatic: if the lid doesn't lend itself, make sure all the screws are twisted. Excessive force will break the plastic ears, and then the lid will hang around when you're in use. After you snap all the locks, smoothly lift the panel.
💡
Use a suction cup for your smartphone screen to gently lift the edge of the lid after twisting the screws – this will reduce the risk of damage to the latches.
Battery Disconnection and Safety Measures
Once the bottom cover is removed, the first thing you see is the battery pack, which takes up a significant portion of the interior space of the Xiaomi Mi Notebook Pro. Before touching any other components, you need to turn off the device.
Find the battery connector to the motherboard, which is usually located in the top or center of the laptop, next to the touchpad or speakers, carefully disconnect the plume by pulling the connector upwards, do not pull the wires, only the plastic head of the connector.
After turning off the plume, it is recommended to press and hold the laptop switch for 10-15 seconds, this action is necessary to completely discharge the residual voltage in the motherboard capacitors, which eliminates the risk of accidental short circuit during further operation.
Visually look at the battery. Bloating, deformation, or oxidation marks on the contacts are alarm bells. If you're planning a battery replacement, now is the time to prepare a new component. The Mi Notebook Pro often uses high-energy density models that require careful handling.
⚠️ Warning: Never puncture or squeeze a lithium polymer battery. Damage to the battery shell can lead to ignition or chemical burn.
Replacement of SSD drive and memory modules
One of the most common reasons for disassembling Xiaomi Mi Notebook Pro is the need to expand storage. These laptops usually use the format M.2 NVMe, which provides high speed read and write data. the replacement procedure is quite simple, if you follow the safety precautions.
Find the M.2 slot on the motherboard. Depending on the model's year of release, it could be a PCIe 3.0 x4 slot. The new drive is set at a 30 degree angle, then fixed by a screw. Make sure that the golden contact is fully included in the connector.
As for RAM, most Mi Notebook Pro models have it soldered directly on the motherboard, which means that it won’t be possible to increase RAM capacity by standard methods. However, some versions may have one free SO-DIMM slot, but this is rare for Xiaomi ultrabooks.
When installing a new SSD, it is important not to confuse the connector keys. Physically incompatible formats will not fit into the slot, but the effort can damage the contacts. After installing the component, take your time to close the cover - first check whether the disk is detected in the BIOS.

Cleaning the cooling system and replacing the heat paste
The cooling system Xiaomi Mi Notebook Pro over time becomes dusty, which leads to overheating of the processor and graphics card. Trottling (decreased performance) and noisy fans are the direct consequences of clogged radiators.
To clean properly, you need to remove the fans, which are usually secured by several screws and wired thinly to the board, turn off the connectors of the fans before dismantling, blow the radiators with compressed air, removing dust from hard-to-reach places.
Special attention is required to replace the thermopaste. The old layer of the thermal interface may have dried out and lost its properties. Carefully remove the remnants of the old paste from the processor and the copper soles of the radiator using an alcohol napkin. Apply the new thermopaste with a thin, even layer.
Don't use too much thermal paste, excess can leak out on the board contacts. For the Mi Notebook Pro, high-conductivity formulations such as the Arctic MX-4 or Noctua NT-H1 are well suited. After assembly, the temperature in the idle should drop by 5-10 degrees.
Put the cooling system back together. Make sure the radiator screws are evenly twisted, diagonally, to ensure tight pressing to the chip.

As you can see from the table, the main potential for upgrades lies in the plane of SSD replacement and cooling system maintenance. Wi-Fi module can also be replaced with a more modern, supportive Wi-Fi 6 standard if the current module is outdated or defective.
When choosing components, be guided not only by price, but also by the heat package.The compact case of the Mi Notebook Pro is sensitive to heat, so energy-intensive SSDs may require additional cooling or heat pads.
💡
The main emphasis during the modernization of Xiaomi Mi Notebook Pro should be made on the replacement of the SSD and quality maintenance of the cooling system, since the memory is soldered.
Assembly of a laptop and checking of working capacity
The final step is assembly. Put the bottom lid back in place, making sure all the latches are in their grooves. Press the perimeter evenly until the characteristic click. Twirl all the screws, but don't drag them over so as not to break the thread in the plastic bushings.
Connect the battery plume to the motherboard, make sure the connector is locked in and locked in, and then you can plug the charger in and turn on the laptop.
When you first start up, the system can go through the POST procedure longer than usual. Check with the BIOS or operating system whether the new SSD is correctly detected and the fan is working. Monitoring the temperatures in the first hours of operation will help make sure that the thermal paste is applied correctly.
If the laptop doesn't turn on, don't panic.Check the battery plume connection and make sure no connector has been forgotten or poorly inserted. Sometimes it helps to re-activate the battery and wait for a couple of minutes.
⚠️ Warning: If you hear a foreign knock or vibration after assembly, turn off the device immediately, which may indicate that the fan is not installed correctly or that a foreign object has hit you.
