How to turn on the keyboard light on Xiaomi laptop

Modern laptops from Chinese giant Xiaomi have long proven to be stylish and functional, but new users often face the odds of managing the hardware. One of these features is the keyboard backlight, which doesn’t always activate automatically when you first turn on or after you reinstall the operating system.

Unlike gaming laptops with bright RGB-illuminations, Mi Notebook and RedmiBook ultrabooks use monochrome white backlight, controlled software through special drivers or hardware key combinations. The lack of visible results when pressing buttons often causes panic, but in most cases the problem lies in the banal lock of the function or lack of the necessary software.

Hardware hotkeys and combinations

The fastest and most obvious way to turn on the backlight is to use the function keys on the keyboard itself. Xiaomi engineers have placed brightness control on the top row keys, but their work depends on the state of the modifier key Fn. Depending on the laptop model, the location of the backlight symbols can vary, so it is worthwhile to carefully inspect the keyboard.

This is usually done by a key called F10 or F9, which has a corresponding icon in the form of a keyboard with glowing beams. If a simple press does not work, you need to press the Fn key (located in the lower left corner) and hold it, press the function key. Some models, such as the Mi Notebook Pro, use double pressing to switch brightness modes.

  • πŸ”˜ Press it once or in combination with Fn to activate it.
  • πŸ”„ Repeated pressing can change the brightness level or turn off the lights.

⚠️ Note: Some Xiaomi laptops do not have a backlight module, even if the keys are marked with the appropriate characters. Check the specification of your particular model on the official website before trying to activate.

It's also worth noting that Windows 10 and Windows 11 may have a keyboard filter feature that blocks quick presses. If the keys are late or not responding at all, check the special features settings. Sometimes short-term disconnection of the laptop from the network and battery extraction (if the design allows), which resets the static charge of the controller.

Software Management through Xiaomi Settings

If the mechanical switching didn’t work, it’s likely that the system doesn’t have proprietary software installed or it doesn’t work properly. Xiaomi Settings (or Mi Settings) is responsible for managing the peripherals in Xiaomi laptops. Without this component, the operating system may not recognize commands sent through the keyboard’s functional series.

You can check the presence and status of drivers through the Device Manager, but the more convenient way is to install the full driver package from the official support site. After installation, you need to restart the laptop to ensure that power and backlight management services are initiated correctly. The program interface often has a brightness slider that duplicates the functions of the keys.

In rare cases, a conflict of software versions can lead to the fact that the slider in the program will be active, and the keys will not. In this situation, it is recommended to completely remove the application through the control panel, clear temporary files and install a fresh version from the manufacturer's website, selected strictly according to the device model.

  • πŸ“₯ Download the current version of Xiaomi Settings from the official portal.
  • βš™οΈ Install the package and perform a mandatory system restart.
  • 🎚️ Check the presence of a slider control lighting in the utility interface.

If the backlight didn’t work after reinstalling the drivers, try rolling the system back to the restore point preceding the latest Windows updates that may have disrupted compatibility.

Settings in BIOS and UEFI

The deep level of iron management is in BIOS (or UEFI). This is where you determine if you're going to put any voltage on the LEDs on the keyboard when you start up, and if you're down at firmware, no keyboard combinations in Windows will work. BIOS keystroke F2 immediately after turning on the laptop.

You should go to the peripheral or system tab (often called Advanced or System) in the settings menu, and look for a setting associated with Keyboard Backlight or KB Light. Make sure the value is set in Enabled. It's also worth checking if the power saving mode is activated, which turns off the backlight when you're running from the battery.

Changes to the BIOS require saving before you exit, usually with an F10 key, followed by a confirmation of action, and when you restart, the system will apply new parameters, and if you're not sure what you're doing, it's best not to change the settings marked as Default, so as not to break the system's tabWork.

⚠️ Note: Unwarranted change of unknown parameters in BIOS This can cause a laptop to work in an unstable way. Only change the settings that are directly related to the keyboard lighting.

Table of compatibility of models and methods

Different lines of Xiaomi and Redmi notebooks may have different implementations of the backlight function. Below is a summary table that will help you navigate the activation methods for popular models.

As you can see from the table, in game models, control is often put into a separate application with advanced customization options for colors. At the same time, the Air and Pro office models rely on standard system calls. If your model is not on the list, follow the general principles of driver search.

Problems with drivers and their solution

A situation where the keys are pressed, but there is no reaction, often indicates a driver conflict. ACPI or HID-Device Manager (devmgmt.msc) should check the Keyboards and System Devices section. The presence of devices with a yellow exclamation mark indicates a problem. Sometimes it helps to simply update the driver through the context menu.

A more radical but effective method is to remove the device from the Manager and then restart. Windows will automatically try to reinstall the driver at start, which often eliminates software errors, and you should also pay attention to the services responsible for the operation of hot keys.

Advanced users may need to check the registry or use the command line to reset power settings. USB-ports to which the internal keyboard is connected. -restoredefaultschemes Resets power circuits to factory ones, which can return functionality.

This command requires administrator rights, and when you use it, you should restart the laptop, and it's safe, and it returns all power settings to their original state, removing potential locks.

Specificity of the operation of the light sensor

Many users don't know that Xiaomi laptops often have an algorithm that depends on external lighting. If the room is very bright, the sensor can programmatically turn off the keyboard's backlight to save energy, even if you turn it on with keys. Try to cover the light sensor (usually located next to the webcam) with your hand and press the switch on button.

This feature is designed to extend the battery life of the device, but it can be annoying if the laptop is under a bright lamp and the user needs backlighting, and you can turn off this automatic adjustment in the same settings Xiaomi Settings, finding the item "Automatically adjusting the brightness of the keyboard."

  • πŸ™Œ Cover the sensor with your hand to check the system response.
  • βš™οΈ Turn off auto-adjustment in the proprietary utility for manual control.
Where is the light sensor?
Usually, the light sensor in Xiaomi laptops is located in the top of the screen, next to the lens of the webcam. This is a small black window that should not be glued with protective films.

Frequently Asked Questions (FAQ)

Why does the backlight only light up when Windows boots and then go out?
It's likely that an inactivity timer or light sensor is triggered. Check the timer settings in Xiaomi Settings and make sure the room isn't too light, and it could also be a sign of a battery dead if the laptop is running in energy saving mode.
Can I change the color of the lighting on the Xiaomi Mi Notebook?
Most office models (Air, Pro) use monochrome white backlight, and it is impossible to change its color software. RGB-backlighting is available only in specialized game lines, if it is declared by the manufacturer in the characteristics.
What to do if the Fn key is blocked?
Some laptops have Fn Lock. Try pressing Fn + Esc (or lock key) to unlock the function row. Then try pressing the light control key again.
Does the absence of Chipset drivers affect the operation of backlighting?
Yes, it does. Chipset drivers provide basic communication between the motherboard and the periphery, and without them, managing the power of the keyboard and other system functions may not work properly or at all.
Is the lack of lighting a marriage?
Many budget Xiaomi laptop configurations are released without the keyboard backlight module to reduce the final cost, and the presence of characters on the keys in such cases is a feature of the universal keyboard used in the factory.
