How to find out the exact model of the Xiaomi Mi laptop: the complete guide

Owners of Xiaomi and RedmiBook often face the need to accurately identify their device, which may be required when searching for drivers, checking compatibility of components or issuing warranties. Unlike smartphones, where information is available in a couple of clicks, on laptops the procedure may not seem obvious, especially if the stickers on the case are erased.

There are many ways to get this data, from simple visual inspection to the use of specialized commands in the operating system. The exact modification of the device is often hidden in the system registry or BIOS, which allows you to find out the truth even in the absence of external marking.

Knowing the full code of the model is essential to correctly selecting parts such as the battery, screen array or keyboard. The wrong part may not fit physically or cause a conflict in the power management system.

Visual inspection of the case and documentation

The easiest and most reliable method that doesn't require the device to be turned on is to search for a sticker. On Xiaomi Mi Notebook and RedmiBook laptops, it's usually located on the bottom cover. Look for a matrix with a barcode that shows the serial number (S/N) and the model (Model).

If the sticker is erased or removed, look at the original box. One side facet always has a white label with a full specification, and it will show a code like XMA1901-CN or TM1901 that accurately identifies the configuration.

You can also find information on the warranty card or purchase check, if they are preserved. The model is often spelled out in full, including the delivery region, which is especially important because the Chinese (CN) and global (Global) versions may have differences in keyboard and preinstalled software.

⚠️ Warning: Do not try to unstick the factory sticker from the bottom cover for curiosity, which can cause the screws underneath to damage or breach warranty conditions if the device is still in service.

In some ultrathin models, the marking can be laser-engraved directly onto the metal. Look at the area around the vents or near the screen hinges. The text can be very shallow and blend in with the color of the case, so use good lighting.

Use of embedded Windows tools

Windows stores detailed hardware information in its registry. The fastest way to access this data is to use the standard System Information utility. Press Win + R key combination, type msinfo32 and press Enter.

In the window that opens, look for the “Model” line, which is where the exact device code, such as the Xiaomi Notebook Pro 15.6 2018 or more, is most often displayed, and you can also see the BIOS version and the base system manufacturer.

An alternative route is through the classic Settings app. Go to System, scroll down to System About. The Device Specification block often lists the commercial name of the laptop, which is easy to search online but less informative for selecting parts.

For a deeper diagnosis, you can run the DirectX diagnostic tool. Enter the dxdiag command in the Start menu. After downloading the utility on the System tab, an ID will appear in the Computer Model field, which often matches the code on the sticker.

Command Prompt and PowerShell for Accurate Identification

For techies, the most informative method is to request data directly from the BIOS via the command line interface, which eliminates possible Windows interface errors and outputs raw data. Open the command prompt (cmd) on behalf of the administrator.

Enter the following command and press Enter:

wmic bios get serialnumber, manufacturer, smbiosbiosversion

This command will output the serial number and version BIOS. However, to obtain a model, a request for a class is more effective. Win32_ComputerSystem. Enter:

wmic computersystem get model, manufacturer

The system will respond with a string containing the exact model name. In PowerShell, the syntax is similar, but you can use more powerful filters. -ClassName Win32_ComputerSystem Provide a structured list of all properties.

💡

WMIC and PowerShell commands refer directly to the motherboard’s SMBIOS tables, so they show data even if the chipset drivers are not installed.

Using the command line is especially useful when the Windows GUI is not working properly or is hanging, and it is the “gold standard” for remote diagnosis when you need to ask the user to dictate an error code or device model.

Monitoring and diagnostic programmes

If the built-in tools seem too complex, third-party utilities will come to the rescue. CPU-Z is the de facto standard for checking the performance of the processor and motherboard. The Mainboard tab in the Model field will show the exact laptop ID.

Another powerful tool is AIDA64, which is a comprehensive database of all components in the Computer -> Total Information section, and you can see not only the model of the laptop, but also the exact model of the screen matrix, the type of memory and the disk controller.

• 🔍 HWiNFO is a free utility that provides a detailed report on the system, including temperature and voltage, with the model in the window header.
• 💻 Speccy is a program from the creators of CCleaner, which displays information in a convenient, understandable form for beginners, highlighting the model in large font.
• 🛠️ Belarc Advisor – creates a full profile of equipment and programs, forming a report in the form of a full-scale report HTML-The model is listed in the Hardware Profile section.

Using specialized software also allows authentication of components. Sometimes unscrupulous sellers can re-add the stickers, but changing the data in SMBIOS or diagnostic utility reports is much more difficult. Comparing data from different programs will help identify inconsistencies.

⚠️ Attention: Download diagnostic utilities only from official developer sites. Using "cracked" versions from torrent trackers can lead to infection of the system by miners, which will hide the real load on the processor.

Model definition via BIOS/UEFI

If the operating system is not booting, model information can be found in the BIOS. To enter the settings menu, you need to press a certain key when you turn on the laptop. For Xiaomi and Redmi devices, this is most often the F2 or F12 key.

Immediately after the Mi logo appears on the screen, the model name and firmware version are often displayed in the top or bottom corner of the BIOS interface. In Advanced Mode, this information is usually located on the main tab Main or System Information.

The BIOS interface on Xiaomi laptops is usually minimalist. Navigation is done with the keyboard arrows. If you see a Product Name or System Model string, that's the value you want. Write it down accurately by observing the register of letters and numbers.

In some cases, especially on older models, you may need to switch the BIOS interface language if it's Chinese by default. However, the model is usually duplicated in Latin. Be careful when changing other BIOS settings so you don't disrupt the system boot.

Specifics of the Mi Notebook and RedmiBook series

The company's line of laptops has its own marking features. Mi Notebook Air series devices often have simpler codes, while professional Mi Notebook Pros and Redmi G gaming ones use complex alphanumeric indexes. For example, the TM1901 could denote the 14-inch 2019 model.

It is important to distinguish between the marketing name (e.g. Mi Laptop Pro 15) and the technical code of the model (e.g. TMH1901). It is better to use the technical code or the exact serial number to search for drivers on the official website, since marketing names can combine several different configurations.

Understanding these differences is critical when buying compatible accessories such as power supplies. Different models may require different power standards and Type-C connectors or round plugs. Mistakes in choosing a charger can lead to slow charging or damage to the power controller.

Checklist of actions during sale or repair

Before you take your laptop to a service center or put it up for sale, you need to collect all the information about the device, which will speed up the diagnostic process and increase customer confidence, and use the following algorithm to prepare the data.

Save this data in a text file or take screenshots. When you contact Xiaomi or an authorized service center, the operator will first request a serial number and model, and having this information at hand will avoid unnecessary calls and expectations.

💡

Take a photo of a serial number sticker and save it in cloud storage, and if the laptop is stolen or lost, this photo will be the main proof of ownership for the police and insurance company.

It is also recommended to check the history of the device by serial number on the official website of the manufacturer, if this feature is available for your region, this will make sure that the warranty ends date and no records of previous repairs, which is especially important when buying used equipment.
