Many series laptop users ASUS Vivobook encounter a situation where they need to work in low light conditions, but the keyboard remains dark. This does not always mean the device is broken; Often the problem lies in the wrong combination of hot keys or the lack of necessary drivers. Modern models are equipped with advanced lighting control systems, which can be hidden from the eyes of an inexperienced user.
Various modifications ASUS Vivobook have their own backlight control features. In some cases, it is enough to press one button, in others, a combination with a range of functions is required. If you can't find the switch you need, don't panic, as the solution usually lies in the software or BIOS settings.
Determining the presence of backlighting and basic activation methods
Before you try to turn on the light, you need to make sure that your specific model ASUS Vivobook generally equipped with this function. Not all budget laptops are backlit, and trying to find keys that don't exist can be confusing. Carefully inspect the function keys (F1–F12) and the space bar.
Look for an icon that depicts a glowing keyboard or rays of light coming from the keys. This symbol is usually found on the keys F3, F4 or F7. If the icon is missing on the case, check the device documentation or specifications on the official website by entering the exact model of your laptop.
The basic activation method involves using a key combination. In most cases this is a combination Fn + key with backlight icon. If you press these buttons and there is no response, the function may be blocked in the system or drivers ATK Package are not installed correctly.

Using proprietary Armory Crate and MyASUS software
For advanced users and owners of gaming or multimedia versions ASUS Vivobook lighting control is carried out through specialized software. ASUS has introduced a centralized settings manager that allows you to flexibly control not only the brightness, but also the color of the light.
The most powerful tool is the utility Armoury Crate. It is often pre-installed on new devices, but if it is not there, you need to download it from the official website. In this application you will find a section Device (Device) where you can select the lighting profile: static color, rainbow effect or pulsation.
If Armoury Crate doesn't fit or doesn't work, try the app MyASUS. It is simpler and is often used for basic settings. Go to the section Customization (Settings) and find the item Keyboard Backlight. Here you can quickly turn the light on or off without going into complex settings.
It is important to note that some new models use technology ASUS Aura Sync. This allows you to synchronize your keyboard backlighting with peripherals such as mice or headphones. For this function to work, a stable Internet connection and the latest version of drivers are required.
⚠️ Attention: If the utility Armoury Crate does not start or displays an error, system files may be damaged. In this case, try completely uninstalling the program through the Control Panel, restarting the laptop and installing the latest version from the manufacturer’s website.

Configuration via BIOS and system parameters
Sometimes software methods do not work, and then you need to turn to the basic system settings - BIOS. This is a low-level shell that controls the hardware before the operating system boots. In some BIOS versions ASUS Vivobook There is a separate item for activating the backlight, which can be disabled by default.
To enter the BIOS when turning on the laptop, press the key F2 or Del. In the menu that opens, go to mode Advanced Mode (usually the key F7). Look for the section Advanced or System Configuration. The item name may vary: Backlight Control, Keyboard Backlight or Lighting.
Make sure the parameter value is set to Enabled (On) or the desired brightness level is selected. If the parameter Disabled, the backlight will not work even if you press hot keys in Windows. Save your changes by clicking F10, and reboot your device.
☑️ Checking BIOS settings
In some rare cases, the setting may be hidden in the Boot or Security. If you cannot find the item you need, use the search inside the BIOS if your version supports this function (usually the F8 or /).
What to do if the BIOS does not save settings?
If the settings are reset after exiting the BIOS, the CMOS battery on the motherboard may be dead. In ASUS laptops it is often built into the battery compartment or has a separate connector. Try resetting the settings to the default state (Load Optimized Defaults) and setting the necessary parameters again.
Installing and updating drivers
Lack of response to key presses is often due to outdated or missing control drivers. Windows OS may not recognize specific keyboard functions unless special utilities from ASUS. Without them, the system simply sees the keyboard as a standard HID device.
The key component is the package ATK Package (or ATKACPI). It is he who is responsible for the operation of hot keys and backlight control. The driver is also critical ASUS System Control Interface. Without these two components, light control is impossible.
Download drivers only from the official ASUS website in the support section for your specific model. Avoid third party driver sites as they may contain outdated versions that are not compatible with your board revision.
After installing the drivers, be sure to restart your laptop. Even if the installer prompts you to continue without rebooting, system power and keyboard services will require a restart to initialize correctly.
| Component | Purpose | Where to find |
|---|---|---|
| ATK Package | Hotkey management | "Chipset" section on the ASUS website |
| ASUS System Control Interface | Link to Armory Crate/MyASUS software | Section "Driver & Tools" |
| Chipset Driver | Basic motherboard operation | "Chipset" section |
| BIOS Update | Control firmware update | Section "BIOS & Firmware" |
Before removing old drivers, create a system restore point. If a new driver version causes conflicts, you can easily roll back the changes to a working state.
Solving power and energy saving problems
One of the common reasons for the backlight to turn off is an aggressive energy saving policy. Laptop ASUS Vivobook Can automatically turn off the lights to extend battery life. This is especially true if you work offline.
Check your Windows power settings. Go to Control panel → Power supply → Setting up the power plan → Change advanced power settings. Find an item in the list Keyboard options or Keyboard backlight.
Make sure the On Battery mode is not set to Off or 0 minutes. Set the timer to turn off the backlight at a convenient time, or select “Never” if constant lighting is important to you.
Also check to see if Power Saver mode is enabled in the Windows Action Center or app MyASUS. In this mode, the system forcibly limits the brightness of the screen and keyboard backlight for maximum autonomy.
⚠️ Attention: If the backlight turns on only when the charger is connected, check that the power adapter is working properly. Insufficient power may force the laptop to turn off power-hungry peripherals.
Correctly setting the power supply allows you to maintain a balance between bright keyboard lighting and device battery life.
Hardware faults and diagnostics
If all software methods have been exhausted and the backlight does not work, there may be a hardware failure. This could be a failure of the LEDs, a broken keyboard cable, or a problem with the power controller on the motherboard.
The first diagnostic step is to check the physical integrity of the keyboard. If the laptop is under warranty, do not open it yourself as this will void the warranty. Contact an authorized service center ASUS.
If the warranty has expired, you can try replacing the keyboard yourself if you have the appropriate skills. In the majority ASUS Vivobook The keyboard is mounted on top of the case and can be turned off with one cable. Make sure the new item is compatible with your model, as connectors may vary even within the same series.
