Disassembling a laptop is a task that scares many, but with the right approach and knowledge of the nuances of the design, you can cope with it yourself, saving on the service center.
In this article, we will take a closer look at the Xiaomi Notebook 9 Pro disassembly process, focusing on key points from tool preparation to removal of the back cover and access to the internal components. You will learn what fasteners are used in this model, how to avoid damage to the plumes and where the most vulnerable parts are located. And to minimize the risks, we have included unique recommendations for working with the aluminum body and cooling system of this series.
Before you start, consider that disassembling your laptop will void the warranty (if it still works). If you are not confident in your abilities, you should contact the professionals. But if you decide to act on your own, follow our instructions Step-by-step.
Preparation for disassembly: tools and security measures
The first step is to collect the necessary tools. For the Xiaomi Notebook 9 Pro, you will need:
- ✅ Screwdriver kit: cross (PH00) flat (1.5 mm) for screws, as well as a plastic mediator or guitar mediator for disconnecting the latches.
- ✅ Suction (optional) – will help to suction the cover if the latches are too tight.
- ✅ Antistatic bracelet or gloves – to protect components from static electricity.
- ✅ Spin tray (or magnetic substrate) – so as not to lose small details.
- ✅ Thermopaste (if you are planning a replacement) – for example, Arctic MX-6 noctua NT-H2.
Important: Xiaomi Notebook 9 Pro has an aluminum body that is easy to scratch. Work on a soft surface (like a towel) and avoid metal tools when disconnecting the latches. Also disconnect the laptop from the network and remove the battery (if possible) before starting work - this will eliminate the risk of short circuit.
⚠️ Warning: In this model, the battery is soldered to the motherboard. If you don't plan to replace it, don't try to disconnect the battery by force - this can damage the board. Instead, work with the power off and the battery dead (leave the laptop off at 12).+ pre-disassembly).
Before you start, take a photo of the back cover of your laptop, which will help you remember the location of the screws when you build. Xiaomi Notebook 9 Pro uses screws of different lengths, and mixing them up is a sure way to damage the board.
Removal of the back cover: secrets of latches and screws
The back cover of the Xiaomi Notebook 9 Pro is mounted on 10 screws and a lot of plastic latches.
- Turn your laptop over and unscrew all the screws around the perimeter. Note: 4 screws are shorter than the others (they are located in the corners).
- After removing the screws, gently apply the lid with a plastic mediator, starting from the upper right corner (there the latches are weaker).
- Swipe the mediator along the perimeter, gradually releasing the latches. Do not put excessive effort — if the lid does not lend itself, check if all screws are twisted.
The feature of this model is that there are additional latches near the screen hinges, which are easy to miss, which will cause the plastic locks to break.
- 🔧 Whether all screws are removed (including those hidden under the rubber leg)?
- 🔍 Are there any undetected latches along the seams?
- 🖥️ Have you forgotten to disconnect the touchpad plume (it goes from the lid to the motherboard)?
⚠️ Note: In Xiaomi Notebook 9 Pro, the touchpad plume passes under the battery.If you do not plan to remove the battery, be extremely careful - damage to this plume will lead to a broken touchpad.
Once the lid is removed, you'll see the insides of the laptop, and we recommend that you take a picture of all the components right away, which will make it easier to reverse assemble.
- 🔌 Fans and speakers connectors.
- 💾 Fastening SSD (This model is used M.2 2280 with PCIe 3.0 support x4).
- 🔋 Battery connector (if you plan to disconnect it).
💡
If the latches are too tight, slightly heat the edge of the cover with a hairdryer (not higher than 50).°C) – plastics will become more elastic and the risk of breakage will decrease.
Access to the cooling system and processor
One of the most popular reasons for disassembling the Xiaomi Notebook 9 Pro is to replace the thermal paste, which uses a dual-channel cooling system with two heat tubes and one fan to get to the processor:
- Disconnect the battery plume (if you haven’t done it before).
- Unscrew 4 screws attaching the radiator to the motherboard (they are marked with a symbol) COOLER board-board).
- Carefully remove the radiator, swaying it from side to side. Don't pull up with force - the thermopaste can "stolen".
After removing the radiator, you will see the Intel Core processor. i5-10210U or i7-10510U (Clean the old thermopaste with isopropyl alcohol (90%+) And a new thermopaste is applied in a thin layer (about the size of a pea) that can leak out onto the components of the board.
| Component | Type of thermal paste | Number of | Notes |
|---|---|---|---|
| Central Processor (CPU) | High temperature (up to 150)°C) | 1 pea (≈0.1 g) | Avoid getting hit on SMD-component |
| Graphics chip (iGPU) | Same as for CPU | 1 pea | In this model GPU processor-integrated |
| Memory chips (RAM) | Thermopaste or heat pad (1 mm) | 2 stripes | It is only used when overheating or overheating. |
| VRM-modules | Thermal gasket (0.5 mm) | If necessary, | Recommended when replacing thermopaste with CPU |
When reassembling, tighten the radiator screws cross-cross to avoid distortion. The optimal puffing moment is 0.6 Nm (use a dynamometer screwdriver, if any).

Replacement or upgrade SSD: know-how
Xiaomi Notebook 9 Pro is equipped with SSD form-factor M.2 2280 with PCIe 3.0 interface x4. Replacing the drive is one of the easiest operations when disassembling, but there are nuances here:
- 🔧 Fixing screw SSD hidden under a black rubber cap (take care of it).
- 🔌 SSD This model supports NVMe protocol, but not all drives are compatible with the Xiaomi controller. EVO Plus or WD Black SN750 work without problems).
- 🛠️ When installing a new SSD Do not forget to transfer the heat pad from the old drive (if it was).
Replacement process:
- Unscrew the fastener screw. SSD.
- Carefully pull the drive at an angle of 30° — he'll come out of the connector.
- Install a new one. SSD, making sure he was tightly in the slot.
- Then, put it in the sleeve (do not squirt it).
⚠️ Attention: After replacement SSD You'll need to reinstall Windows or clone the system from an old drive. Xiaomi laptops are often tied to the motherboard serial number, and Windows activation may not go through automatically. USB-installation media with drivers (they can be downloaded on the official Xiaomi website in the support section).
If you are planning to use the old SSD As an external storage device, buy an adapter. M.2 → USB 3.1. for example, ORICO M2PV-C3). This will allow you to transfer data or make a backup before reinstalling the system.

Cleaning the cooling system: how to remove dust without disassembling the fan
Dust is the main enemy of any cooling system. In the Xiaomi Notebook 9 Pro, the fan is located next to the radiator, and its blades quickly clog.
- Remove the back cover (as described above).
- Disconnect the fan connector from the motherboard.
- Use a soft brush or compressed air can to remove dust from the blades and radiator.Don't blow too much - this can damage the fan bearing.
- For deep cleaning, moisten the cotton swab in isopropyl alcohol and gently wipe the blades.
If the fan is creaking or not rotating, it will have to be replaced.The Xiaomi Notebook 9 Pro uses a Sunon model fan. PF40101VX-Q000-S99 (or similar. When replaced:
- 🔧 Unscrew 4 screws of fan attachment to radiator.
- 🔌 Disconnect the power connector.
- 🛠️ Install a new fan, making sure the blades rotate freely.
After cleaning or replacing the fan, check its operation in the BIOS (F2 If the laptop is still overheating, the problem may be in thermotubes (they sometimes dry out over time) or a faulty thermal sensor.
💡
Regular cleaning of the cooling system (once in a week) 6-12 It extends the life of the laptop and prevents the processor from trotting. If you are not sure about yourself, trust this procedure to the service center.
Common Mistakes and How to Avoid Them
