Modern ultrabooks from Xiaomi are famous for their minimalist design and high performance, but over time, even the most reliable device requires maintenance. Users often face the need to clean the cooling system from dust, replace dried thermal paste or increase the amount of RAM. Self-disassembly laptop is a great way to save money at the service center and extend the life of the gadget, if you perform all the actions carefully.
Before you start any manipulation with internal components, it is important to understand that the Xiaomi Notebook 5 (also known as the Xiaomi RedmiBook 14 II or Mi Notebook Pro 14 depending on the region) has a dense layout. Dismantling errors can damage the plumes or body, so you need to prepare a workplace and a specialized tool. In this article, we will look in detail at the process of opening the case, disconnecting the battery and safely removing key modules.
It is worth considering that any interference with the design of the device can affect the warranty obligations of the manufacturer. If the laptop is on warranty, it is better to contact an authorized service, but if you are confident in your abilities and the device has already left the warranty period, follow our instructions Step-by-step.
Tools and workplace preparation required
The Xiaomi Notebook 5 is not a good disassembly without the right tools. Using inappropriate items like kitchen knives or thick screwdrivers is guaranteed to result in scratches on the aluminum body or licking of screw screws. You will need a set of precision screwdrivers, in particular a cross PH0 or PH00, since screws in ultrabooks are usually small.
Besides screwdrivers, it is critical to have plastic mediators, shoulder blades or old credit cards on hand to open the case. Metal tools can damage internal cables or shorten contacts on the motherboard. Also remember to have tweezers to extract small screws and an antistatic bracelet or gloves to protect electronics from static discharge.
☑️ Preparation for the disassembly of the laptop
The organization of the workspace is the key to success. The light should fall evenly so that you can see all the screws and latches. Prepare a magnetic mat or several small containers in advance to sort the screws by disassembly stages, because the Xiaomi Notebook 5 can use screws of different lengths, and you can not confuse their installation locations.
Primary actions: power cut and removal of the back cover
The first and most important step is to completely disconnect the device from the network and turn it off. Don't leave the laptop in sleep mode - complete the complete shutdown procedure through the operating system menu. Turn the device up with the bottom lid and make sure that there are no metal objects on the work surface that could accidentally close contacts.
In the Xiaomi Notebook 5, all the screws holding the bottom cover are located around the perimeter of the body. In some versions, two screws can be hidden under rubber legs, so carefully examine the bottom. Carefully twist all visible screws, taking care not to damage the thread. Once all screws are removed, the lid will not be removed itself - it is held on plastic latches.
⚠️ Warning: Never use force to tear off the lid. The plastic latches in ultrabooks are very fragile and break when jerked abruptly, leading to the appearance of backlash and creaking of the case in the future.
To snap the locks, use a plastic blade. Start at the corner where the logo is or closer to the hinges, and carefully steer the tool along the junction, hearing the characteristic clicks. Move around the perimeter, gradually releasing the lid. The plumes can be pulled, so don't open the lid too wide until you make sure nothing is in the way.
💡
Before you completely remove the lid, take a photo of the internal location of the screws - this will help to remember which screw to twist when assembly.
Battery shutdown: a critical safety step
Once the bottom cover is lifted and you have access to the insides, do not rush to completely remove the panel. The first thing you need to do is find the battery connector on the motherboard. In the Xiaomi Notebook 5, the battery occupies a significant part of the space, and the connector is usually located in the central or near-touchpad part.
Use a plastic shoulder blade or a gloved finger to turn off the power plume. Carefully pull the connector upwards, avoiding jerking over the wires. Only after the battery is physically turned off can the laptop be considered safe for further manipulation, and this will prevent accidental short circuits when the components are touched by the tool.
💡
Shutting down the battery is a must before any work inside the laptop, even if you simply change the SSD. Ignoring this step can cause the motherboard to burn.
After the power is turned off, press and hold the power button for 10-15 seconds, which will relieve the residual voltage from the capacitors on the board, which is the standard for safety when working with modern electronics, and now you can safely remove the lid and start servicing other nodes.
Modernization of memory and storage
One of the main reasons for the Xiaomi Notebook 5 disassembly is the user’s desire to improve performance. In this model, the RAM slot can be sold on the board or represented by one free slot, depending on the specific revision of the motherboard. If the slot is present, you can replace the module with a more capacious one, observing the DDR4 standard.
To replace the drive, find the M.2 NVMe SSD slot. It's usually closed with a metal plate for better heat sink. Unscrew the screw that locks the SSD and it will rise at a 30 degree angle. Gently remove the old drive and install the new one by slamming it tightly into the connector and locking it with a screw.
Compatibility of SSD Disk Compatibility
When installing new components, it is important not to drag the screws. Excessive force can damage the thread in the soft metal of the case or, worse, lead to cracks on the board itself. All connections should be tightened tightly, but without fanaticism.
Maintenance of the cooling system and replacement of thermopaste
The cooling system in Xiaomi Notebook 5 is represented by copper heat pipes and a fan. Over time, the radiator gets clogged with dust and the thermopaste dries out, which leads to trolling (reduced processor frequency) and noisy work. To clean the fan, use a soft brush and a can of compressed air, holding the blades so that they do not rotate too quickly.
Replacing the thermopaste is a more delicate process. You'll need to remove the screws that hold the radiator on the processor. Unscrew them cross-to-cross, gradually loosening the clip so as not to damage the crystal. Clean the old paste with alcohol napkins and apply the new one in a thin, uniform layer.
| Component | Frequency of service | Materials required |
|---|---|---|
| Fan | Every 6-12 months | Brush, compressed air |
| thermopaste | Every 1-2 years | Thermopaste (Arctic, MX-4), alcohol |
| RAM contact | Replacement/cleaning | Laste, dry cloth |
After applying the paste, set the radiator back, twisting the screws also cross-cross for even distribution of pressure. Uneven pressing can cause one of the areas of the processor to overheat.
Laptop assembly and initial launch
The Xiaomi Notebook 5 build process is reversed. Make sure all the plumes are connected tightly and up to the click, especially the touchpad and keyboard plume, which often forget to reconnect. Put the bottom cover in place and evenly press the perimeter until all the latches fall into place.
Once you have the lid, you need to turn all the screws around. Don't leave any screws out of hand -- if you do, you've got a mounting point that's not closed, and the body will creak. Connect the charger and turn on the laptop.
⚠️ Warning: The first start after the battery is turned off may take longer than usual.The system is self-testing the equipment, so don't be alarmed if the screen is black for a period 10-20 seconds.
Check all ports, keyboards and touchpads. If everything is working correctly and the temperature in the idle is within normal limits, then the Xiaomi Notebook 5 disassembly was successful. Regular maintenance significantly extends the life of the equipment.
