How to safely remove the battery from Xiaomi Notebook Pro: instructions with photos and tips

Xiaomi Notebook Pro laptops (including Pro 15.6, Pro X 15 and Pro 14) are known for their performance and stylish design, but over time, even the best battery loses capacity. If your laptop starts to run out in an hour or refuses to turn on without a connection to the network, it’s probably time to replace the battery. However, self-dismantling the battery is not an easy task: requires accuracy, the right tools and knowledge of the nuances of design.

In this article, we will analyze the step-by-step process of removing the battery, taking into account the features of the Xiaomi Notebook Pro model range, list the necessary tools and warn about typical errors that can lead to damage to the device.

If you've never taken a laptop apart before, we recommend that you carefully study each step and not start dismantling without an antistatic bracelet and insulated screwdrivers, otherwise static electricity or short circuit can disable not only the battery, but also the motherboard.

Preparation for dismantling: tools and security measures

Before you start disassembling the Xiaomi Notebook Pro, make sure you have everything you need. Not even one tool can complicate the process or make it impossible. Here is the minimum set you will need:

• 🔧 A set of screwdrivers with magnetic tips (required) PH00, PH0 flat-latched).
• 🧲 Antistatic bracelet or gloves – to protect components from static discharge.
• 📦 Plastic mediators (2-3 pc.) - for careful separation of the body without scratches.
• 🔋 Multimeter (optional) – to check the voltage at the contacts of the battery before disconnecting.
• 📸 Smartphone or camera – to capture the location of screws and cables.

Pay special attention to security measures:

• ⚡ Turn off the laptop and remove the charger 10-15 minutes before work starts, which will discharge the residual energy in the capacitors.
• 🔥 Do not work near open fires or heat sources – lithium-ion batteries ignite when damaged.
• 🚫 Do not use metal objects to tamper with the battery – this can cause a short circuit.

⚠️ Warning: If the battery is swelling or deformed, do not try to remove it yourself. In such cases, the risk of fire or explosion is extremely high - contact the service center.

Before you start, back up your data. Although the battery is not affected by the drive, there is always a risk of accidental damage to the cables or board.

Step 1: Shutting off power and removing the back cover

The first step is to turn off the power and access the internal components, starting with the power supply shutdown.

1. Turn off the laptop through the Start menu → Completion of work.
2. Disconnect the charging cable from the socket and laptop.
3. Turn the device over and hold the power button for 30 seconds, which will discharge the residual energy in the capacitors.

Now, let's get to the back cover, and in the Xiaomi Notebook Pro, it's mounted on screws and latches.

1. Unscrew all the screws around the perimeter of the lid (usually 10-12 pieces). The screws can vary in length - remember where you were, or take a picture.
2. Insert a plastic mediator into the gap between the lid and the body and guide them gently around the perimeter, snapping the mounts. Start at the corner next to the screen hinges.
3. After all the latches are disconnected, remove the cover and put it aside.

⚠️ Warning: Don't use excessive force when you cleave the lid -- on the Pro X 15, plastic clips break easily. If the lid doesn't lend themselves, check if all screws are twisted.

Under the lid, you'll see the motherboard, the cooling system and the battery, and at this point, don't touch the components with your bare hands -- use an antistatic bracelet or gloves.

Step 2: Disconnect the battery from the motherboard

Before you physically remove the battery, it must be disconnected from the power system. in laptops Xiaomi Notebook Pro battery is connected via the FPC-A plug (flexible plume) or a standard connector:

1. Find the battery connector on the motherboard, which is usually located next to the battery and is labeled as BATTERY or BATT.
2. Carefully apply the black lock (if any) up or sideways to release the plume. Don't pull the wires!
3. Remove the plume from the connector by holding it by the plastic part, not the contacts.

On some models (e.g. Pro X 15), the connector may be soldered.

• 🔧 Use a soldering station with a temperature not higher than 300°C.
• 🕳️ Before soldering, cover the neighboring components with heat-resistant tape.
• ⚡ After despatch, check with a multimeter the lack of voltage on the contacts of the battery.

If you're not sure about your rationing skills, you should contact the service. The wrong ration can damage the motherboard.

💡

If the laptop doesn't even turn on after the battery is turned off, check if the power supply is connected correctly. The short circuit protection may have worked - wait 5-10 minutes and try again.

Step 3: Removing the battery from the housing

After disconnecting the battery from the board, you can begin to physically dismantle it. In Xiaomi Notebook Pro laptops, the battery is usually attached to:

• 🔩 Screws (2-4 pcs) around the perimeter.
• 🧲 Double-sided scotch or duct tape.
• 🔗 Plastic latches (rarely).

Procedure:

1. Unscrew any screws that attach the battery to the case. They can be hidden under stickers or rubber legs - gently tuck them in.
2. If the battery is glued, don't try to rip it out. Tap the edge with a plastic mediator and slowly pull it, applying a uniform force. Use isopropyl alcohol if necessary to dissolve the glue.
3. Remove the battery by holding it by the edges. Don't bend or deform the battery case.

⚠️ Warning: If the battery starts to hiss, heat up, or deform when it is removed, immediately place it on a non-combustible surface (like ceramic tiles) and leave the room. These are signs of thermal acceleration - the battery may ignite.

On some models (e.g. the Pro X 15), the battery can be split into two modules, in which case remove them one by one, starting from the one closest to the edge of the case.

Step 4: Checking a new battery before installing

Before installing a new battery, be sure to check its compatibility with your Xiaomi Notebook Pro model. Even if the batteries look the same, they may differ:

• 🔌 Voltage (e.g., voltage, 11.4V vs 11.55V).
• 🔋 Capacity (56Wh, 60Wh, 66Wh etc.).
• 🔌 Connection connector (number of contacts).

To verify:

1. Compare the original battery article (printed on the sticker) with the new one. For example, for Xiaomi Notebook Pro 15.6 it could be MDY-06-56.
2. Check the voltage multimeter - it must correspond to the original (permissible deviation). ±0.1V).
3. Make sure that the connection connector matches in shape and number of contacts.

If you bought a battery that was not original, pay attention to the build quality:

• 🔍 Check if there are any swelling or deformation of the body.
• 🧲 Make sure that the contacts are not oxidized or bent.
• 📄 Require a quality certificate from the seller – this will reduce the risk of buying a defective battery.

💡

Never install a battery with a voltage different from the original, even if the connector is suitable, which can cause the power controller to overheat, catch fire, or fail.

Step 5: Install a new battery and build a laptop

Once the new battery is tested, you can start installing it.

1. Carefully insert the battery into the grooves of the case, make sure it fits tightly and is not skewed.
2. Secure it with screws (if any) Don't drag it over, it could damage the battery case.
3. Connect the battery plume to the motherboard connector, make sure the lock is snapped.
4. Check that there are no gaps between the battery and the case – this may indicate an incorrect installation.

After the battery is installed:

1. Make sure all cables and plumes are connected correctly.
2. Close the back cover by snapping all clips around the perimeter.
3. Turn the screws in reverse. Start with the corners, then move to the center.

Before first inclusion:

• ⚡ Connect the charger and let the battery charge to at least 20% before first starting.
• 🔄 Calibrate the battery: fully charge, then discharge to 5% and recharge to 100%.

⚠️ Warning: If the laptop doesn't turn on after assembly, don't panic. Turn off the charger, remove the battery (if possible) and hold the power button for 60 seconds. Then reconnect. Often this helps to reset short circuit protection.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when replacing a battery, and here are the most common mistakes and ways to prevent them:

Another common problem is that the laptop doesn't see the new battery, and the reasons may be:

• 🔌 Bad contact in the connector - check if the plume is inserted to the end.
• 🔋 Incompatible controller – some non-original batteries require firmware BIOS.
• 🖥️ Failure in the system - try to reset BIOS (take out the battery CMOS 10 minutes).

If the battery is quickly discharged after replacement, you may need to update the power management drivers. download them from the official Xiaomi website.
