Users often face a situation where it is necessary to accurately identify a device, whether it is to find drivers, issue a warranty or purchase compatible accessories. Owners of Xiaomi equipment and the RedmiBook sub-brand are no exception, especially given that the marking on the case is sometimes erased or glued. Understanding how to find out a specific modification will save you a lot of time when contacting the service center.
There are many software and hardware methods available to get a comprehensive grasp of hardware, and we'll look at both standard Windows tools and specialized utilities that show hidden data, and it's important not to confuse the commercial name that's on the box with the technical identifier that engineers use.
In this article, we will take a look at every available method, from simply inspecting the sticker to using console commands, learn to distinguish between the Mi Notebook and RedmiBook series, and understand why the model's code can differ from what is written on the price tag in the store.
Search for information on the body and packaging
The most obvious and quick way to avoid switching on the device is to do a visual inspection, but manufacturers often hide technical information in non-obvious places to avoid spoiling the minalistic design of the aluminum case. Carefully examine the bottom cover of the laptop: there should be an information sticker or engraving.
Look for a string labeled Model or MD. It's usually made up of alphanumeric code, like JYU4087CN or RBJ05JPCN. It's the key to looking for specifications on the official website. A commercial name like "Xiaomi Notebook Pro 15" can connect multiple generations with different processors, and the technical code indicates a specific revision.
If the sticker on the bottom is worn out (which is often the case with aluminum surfaces), check the original box.One side of the cardboard packaging always has a sticker with a barcode and a full list of characteristics, including the exact motherboard model and the factory-installed version of the BIOS.
- 🔍 Inspect the bottom cover for fine print engraving next to regulatory marks.
- 📦 Find the original box and learn white barcode stickers.
- 🔋 Remove the battery if it is removable (relevant to older models), and look under it.
- 🧾 Check the warranty card or check, which often prints the full article of the device.
⚠️ Warning: Do not use aggressive chemicals or abrasives to clean the bottom cover in an attempt to read the worn marking.You may damage the protective coating or wipe the aluminum body through.
Sometimes the commercial name and technical code are very different. For example, a device can be sold as RedmiBook 14, but have an internal index RBJ05JPCN. To search for drivers on the support site Xiaomi better use a technical index, because a search for a beautiful name can give results for all revisions at once.
Use of embedded Windows tools
If the laptop is powered on and the operating system is functioning properly, you won't need third-party software. Windows has a powerful diagnostic tool called System Info. To run it, press Win + R and type in msinfo32.
In the window that opens, look for System Model, which will show the exact device code that matches the labeling on the case, and look for System Manufacturer, which should be Xiaomi or Redmi, which is taken directly from the BIOS/UEFI, so it is the most reliable.
The alternative is to use the command line, which is convenient because you can quickly copy the result, open the command prompt (CMD) or PowerShell on behalf of the administrator and type a special request to the Windows Management Instrumentation (WMI).
wmic bios get serialnumber, manufacturer, versionThis command will output the serial number, manufacturer and BIOS version. Although there may not be a complete model code, the serial number often contains encrypted information about the production date and manufacturer, which is useful when checking warranty.
☑️ Verification through Windows
Another hidden resource is PowerShell. Get-CimInstance lets you pull the same data out in a more modern way. -ClassName Win32_ComputerSystem | Select-Object Model, Manufacturer. The result will be displayed in the form of a table, where the model will be specified exactly as the system sees it.
Diagnostics via BIOS and UEFI
If the operating system is not loading or is unstable, model information can be obtained at the BIOS/UEFI level. This is the “hardware” layer where model data is written forever. To log into the BIOS on Xiaomi laptops, the F2 key is usually used when turned on.
Once you’ve entered the BIOS interface (often a blue or gray screen with a text menu), look for the Main or Information tab. The Product Name or System Model section will show the code you want. Some RedmiBook models display this information directly on the Splash Screen logo in the first seconds of activation, before Windows boots.
It is important not to confuse the BIOS version with the laptop model. The BIOS version (e.g., 1.08) speaks of the microcode version, and the model (e.g., TM1701) speaks of the physical device. Write the code accurately, observing the register of letters if it is present.
| Parameter | Where to look in the BIOS | Example of meaning |
|---|---|---|
| Model | Main / Product Name | XMA1901-CN |
| Serial number. | Main / Serial Number | 2040567890 |
| BIOS version | Main / BIOS Version | 1.15.0 |
| UUID | Advanced / UUID | 12345678-1234-... |
In some cases, especially on global versions of laptops, the BIOS menu can be simplified: If you haven't found the "Model" line, look for "OEM Model" or just look closely at all tabs, including Security or Boot, although this is rare.
What to do if the F2 key is not working?
Third-party utilities for identification
When embedded tools are scarce or require the most detailed information about components (such as the type of screen matrix or memory vendor), specialized programs come to the rescue. The leader in this area is the utility CPU-Z. It is free, weighs little and requires no installation.
Once you start CPU-Z, go to the About tab and click the Save Report button in TXT. In the text file in the DMI -> BIOS section, you will find the Manufacturer and Product fields. It is the Product field that contains the exact model. This is the most reliable software method.
Other popular programs like AIDA64 or HWiNFO also do a great job. In AIDA64, you need to go to the System Board -> SMBIOS section, and there will be detailed information, including the body version and the system serial number, and these data are read from the DMI (Desktop Management Interface) - a special table in the BIOS.
- 💻 CPU-Z — Best choice for quick model and processor checks.
- 🛠 AIDA64 — Professional tool with detail of each component.
- 📊 HWiNFO is a great program for monitoring temperature and sensors in real time.
- 📝 Belarc Advisor – creates a full profile of equipment HTML-report.
Using heavy driver collectors (like DriverPack) to define a model is a bad idea, they often misidentify the device or install unnecessary software, and it is better to use light diagnostic tools that only read information without making changes to the system.
💡
When using CPU-Z on Xiaomi laptops, pay attention to the line "Max CPUID." If it is too old, the program may not correctly identify new processors. In such cases, always update the utility to the latest version from the official website.
Decoding of Xiaomi and RedmiBook model codes
Understanding the naming logic will help you navigate your device lineup. Xiaomi and Redmi model codes often contain encrypted data about the screen diagonal, release year and processor series. For example, code can begin with TM (Mi Notebook), RY (RedmiBook) or JY (Mi Notebook Air/Pro).
Codes containing 14 or 15 are usually 14- or 15-inch models. Letter prefixes can indicate a region: CN at the end of the code often means the Chinese version, although this may not be explicitly displayed in global firmware.
The Mi Notebook series (now often just Xiaomi Notebook) are marketed as premium devices with a metal body and quality screens.The RedmiBook series is geared towards the mass market and students, offering good value for money, but sometimes with plastic elements or less bright matrices.
⚠️ Attention: Don't try to stitch BIOS Even if the laptops look identical, differences in the processor bandage or power controller can cause the device to fail permanently (brick).
Knowing the exact model is especially important when searching for spare parts. Keyboards, matrix plumes and batteries on Xiaomi Mi Notebook Pro 15 2018 and 2019 models may differ, despite the similarities. So when ordering repairs in the service, always dictate the full code from the sticker.
💡
The exact model code (e.g. JYU4087CN) is more important than the commercial name (Mi Notebook Pro) because it ensures that parts and drivers are compatible.
