How to disassemble Xiaomi RedmiBook Pro 3 without damage: instructions with photos and tips

Self-disassembly of Xiaomi RedmiBook Pro 3 is a challenge that scares many users. Fear of breaking fragile latches, damaging plumes or losing warranty often stops even experienced enthusiasts. However, with the right tools and step-by-step instructions, the process becomes predictable and safe. This laptop, released in 2021, is still popular due to the balance of price and performance, but its upgrade (for example, replacing an SSD or RAM) requires accuracy.

Unlike many budget laptops, the RedmiBook Pro 3 has soldered RAM (as standard), but supports replacing the M.2 NVMe drive. This makes disassembly advisable for increasing storage capacity or diagnosing the cooling system. In this article, we will discuss the process from tool preparation to reassembly, taking into account the typical errors and unique design features of this model.

Before starting work, be sure to study the FAQ at the end of the article - there are answers to frequent questions about the compatibility of components and the nuances of warranty service.

1.Preparation: security tools and measures

You need a minimal set of tools to disassemble the RedmiBook Pro 3, but each one is important. If you don't have one, you can chip plastic or damage the plumes.

• 🔧 Plastic mediators (2-3 - for the tidy fitting of latches. Metal tools are prohibited!
• ⚡ Torx screwdriver T5 — for the back cover screws (usually 8-10 piece).
• 🧲 Magnetic mat or container – to avoid losing small details.
• 📸 Smartphone for photography – fix the location of plumes and screws before disconnecting.
• 🔌 Antistatic bracelet (optional, but recommended to protect the motherboard).

Pay special attention to the workplace: it should be clean, well-lit and without static electricity. Do not disassemble the laptop on the carpet or the sofa, this can lead to a discharge that will damage the chips. Also make sure that the battery is discharged to at least 30%, this will reduce the risk of short circuits in case of accidental closure of contacts.

⚠️ Note: If your RedmiBook Pro 3 is still warranty-worthy, disassembly will void it. In some Xiaomi service centers, repair may be refused even if there are cosmetic autopsy marks. PC Suite before the start of work.

2 Removal of the back cover: a step-by-step process

The back cover of the RedmiBook Pro 3 is mounted on 8 Torx T5 screws and a lot of plastic latches, and the main challenge is not to break them when you're undercoat.

1. Turn off the laptop, disconnect the charger and turn it upside down.
2. Unscrew all the screws (they can be of different lengths - remember the location of each!). In RedmiBook Pro 3, usually: 4 screws at the corners (long). 4 screws in the middle (short).

If the lid doesn't lend itself, don't apply force! You probably missed the screw or the latch. RedmiBook Pro 3 often has a hidden screw under the rubber leg (usually in the center). Carefully tuck it in and check.

3. Battery disconnection: why it's critical

Before any manipulation of the internal components, be sure to disconnect the battery. In the RedmiBook Pro 3, it is connected to the motherboard through a wide plume with a JST PH 2.0 connector.

1. Find a battery, which takes up almost half of the interior space.
2. Carefully tuck the plastic latch of the connector (usually black) and pull the plume up. Don't pull the wires!
3. After disconnecting, check with a multimeter that there is no voltage on the contacts (optional, but recommended for safety).

If you miss this step, the risk of short circuits when you accidentally touch the motherboard with a metal tool increases dramatically, at best, it will cause the BIOS to reset, at worst, it will cause the power controller to fail.

⚠️ Attention: In some RedmiBook Pro 3 batches, the battery is glued to the body with double-sided tape. Do not try to tear it off by force - use a plastic spatula and heat the area with a hairdryer (temperature not higher than 60).°C) to soften the glue.

4. SSD Replacement: Compatibility and Nuance

RedmiBook Pro 3 supports M.2 2280 NVMe PCIe 3.0 x4 drives, which means you can install any modern SSD with this specification, for example:

• Samsung 970 EVO Plus (up to 2 TB)
• WD Black SN750 (up to 2 TB)
• Crucial P5 Plus (up to 4TB, but check for BIOS compatibility)

Replacement process:

1. Find the M.2 slot – it is located next to the battery and is closed with a metal cover, fixed with one screw.
2. Unscrew the screw and gently lift the lid. The old SSD can be locked with a latch, and you can squeeze it.
3. Insert the new drive at a 30° angle, then press until you click. Secure it with a screw.

After replacing the SSD, the laptop may not see it immediately.

• Go to the BIOS (F2 button when booting).
• Check if the drive is displayed in the Boot section.
• If not, upgrade your BIOS to the latest version (instructions on Xiaomi’s official website).

💡

Before buying an SSD, check its compatibility with the RedmiBook Pro 3 on the manufacturer’s website.Some models (such as the Samsung 980 Pro) may not be supported due to BIOS limitations.

5.Diagnostics of the cooling system: when to clean

If your laptop gets overheated (processor temperature above 90°C under load), the cause may be dust in the radiator or dry thermopaste. In RedmiBook Pro 3, the cooling system consists of:

• Two heat tubes (for CPU and GPU).
• One fan with copper ribs.
• Dow Corning TC-5622 (factory) thermopasts

For cleaning:

1. Remove the cooling system (4 screws around the radiator).
2. Remove the old thermopaste with a napkin soaked in isopropyl alcohol.
3. Apply the new paste (recommended by Arctic MX-6 or Noctua NT-H2) with a thin layer.
4. Blow the radiator with compressed air (canister) or rinse with water (after drying completely!).

⚠️ Warning: When removing the radiator, don't pull the heat pipes - they are fragile and can detach from the base. If this happens, the laptop will overheat even after assembly, and you will need soldering.

6.Reverse Assembly: How not to forget anything important

The RedmiBook Pro 3 should be built in reverse order, but there are a few critical points:

• 🔌 Before connecting the battery, make sure that all the plumes (touchpad, keyboard, display) are connected tightly.
• 🔧 Twisting the screws cross-cross to avoid skewing the cover.
• 📋 Check that the rubber legs fall into place – they prevent vibration when the fan is working.

After assembly, turn on the laptop and check:

1. Is the touchpad and keyboard working?
2. Is the new SSD determined (if replaced)?
3. Is there any extraneous noise from the fan (this may indicate dust or improper installation of the radiator).

If the laptop does not turn on:

• Check the battery connection and power plume.
• Remove SSD and RAM (if any) – if the laptop is showing signs of life (the fan is spinning), the problem is with one of these components.
• Reset the BIOS by removing the CR2032 battery for 10 seconds (located under a metal cover next to the battery).

💡

The most common build error is to forget to plug the touchpad plume. If the touchpad doesn't work after turning on, don't panic: just take the laptop apart again and check the connector (it's located under the battery).

7. Frequent mistakes and how to avoid them

Even experienced users sometimes make mistakes when disassembling RedmiBook Pro 3, and here are the most common ones and ways to prevent them:

• 🔧 Broken lid latches – use only plastic mediators and heat the edge of the lid with a hairdryer to soften the plastic.
• ⚡ Short circuit – always turn off the battery and work on an antistatic mat.
• 💾 Undetectable SSD — Check the compatibility of the storage model with BIOS laptop.
• 🔥 Overheating after assembly - apply the thermopaste in a thin layer and evenly twist the radiator screws.
