How to enable and configure the keyboard backlight on an ASUS Vivobook laptop

Modern laptop series ASUS Vivobook have become the standard for students and office workers due to their balance between price and performance. However, many users are faced with an unexpected problem: they cannot find the button to turn on the keyboard backlight or it simply does not respond to presses. This often causes confusion, especially if the store's lighting seemed bright and attractive during the display.

The reason for the lack of light may lie in several factors: from a simple software glitch to the lack of hardware support in a particular configuration. In this article we will discuss in detail how to activate keyboard backlight on ASUS Vivobook, what key combinations to use and what to do if standard methods do not work.

Do not immediately blame the manufacturer or assume that the device is faulty. In most cases, the problem is solved by setting hotkeys or updating drivers. We'll cover all possible scenarios so you can quickly get back to comfortable working in low-light conditions.

Checking hardware support and key labeling

Before you begin complex settings, you need to make sure that your laptop is equipped with this feature at all. Not all models in the series ASUS Vivobook are backlit, even if they look identical. Manufacturers often use different configurations for the same model depending on region and price.

Carefully inspect the key F7 or F3 on your device. Look for an icon that depicts a key with rays of light or just a glowing key. If there is no such icon on any function key, most likely your version of the laptop does not physically have a backlight. This is not a breakdown, but a feature of the configuration.

It is important to note that the presence of backlighting often depends on the type of matrix and regional version. For example, models for the European market may be backlit, while Asian versions of the same series may be simplified. Check the documentation at ASUS Vivobook, if you still have it, or find the exact model on the sticker on the bottom cover.

• 🔍 Inspect the top row of keys (F1–F12) for the presence of a backlight icon.
• 🔍 Check the sticker on the laptop case indicating the presence of the Backlit Keyboard function.
• 🔍 Look at the specifications of your model on the official ASUS website.

⚠️ Attention: If there is no special backlight icon on the keyboard, no key combinations or programs will be able to turn on the light, since the LEDs are not physically installed on the board.

Sometimes the icon may be very small or dim, especially on dark keys. Use your phone's flashlight to look closely at each button. If you still find the icon, but it does not work, proceed to the next step of checking the software settings.

Using keyboard shortcuts to activate

If hardware support is confirmed, the next step is to enable the feature via hotkeys. On most laptops ASUS Vivobook The function row is used to control the backlight. Usually this is a key F7 or F3 depending on the model year.

Try pressing the key F7 on your own. If nothing happens, hold down the key Fn (usually located in the lower left corner) and, while holding it, press F7. Sometimes the reverse combination is required: first Fn, then a button with an icon. This is the standard mechanism for function keys on laptops.

In some new models ASUS Vivobook With OLED screens or premium designs, controls can be implemented via a separate button or even a touchpad, but this is rare. The main method remains the keyboard combination. Try pressing the backlit key several times, as it may have multiple brightness settings.

Please note that the backlight can have several brightness levels. The first press can turn it on to minimum power, the second to medium, the third to maximum. The fourth press usually turns off the light. This is a logical control system that allows you to adapt the lighting to the current conditions.

• 🔸 Click F7 or F3 without additional keys.
• 🔸Pinch Fn and press the key with the backlight icon.
• 🔸 Try the combination Fn + Space (if the icon is on the spacebar).

Setup via Armory Crate and MyASUS app

Modern laptops ASUS Vivobook equipped with proprietary software that allows you to flexibly configure the device. One such tool is Armoury Crate or MyASUS. These programs give finer control over RGB backlight, if it is supported by your model.

Launch the application Armoury Crate from the Start menu. Go to section Device (Device), then select the tab System or Lighting. Here you can not only turn on the backlight, but also adjust its color if the keyboard supports multi-color backlighting. In simple models, settings can be limited only to brightness.

In the application MyASUS You can also find peripheral settings. Go to section Customization (Settings) and see if there is an item there Keyboard Backlight. Sometimes this is where you can switch the key mode from “Function” to “Multimedia”, which can solve the problem with the lack of response to F7.

If you don't see the settings you need, the app may be outdated. Go to the Microsoft Store or the official ASUS website and download the latest drivers and utilities. Software updates often fix bugs that prevent the backlight from being controlled by software.

• 🔹 Open Armoury Crate and find the backlight section.
• 🔹Check your settings in the app MyASUS.
• 🔹 Update your software through the Microsoft Store.

Installing and updating keyboard drivers

A common cause of backlight not working is an outdated or damaged keyboard driver. Windows may not correctly detect the capabilities of your device if proprietary drivers from the manufacturer are not installed. This is especially true after updating the operating system.

To check, open Device Manager (Device Manager). You can bring it up through search in the taskbar or by right-clicking on the Start menu. Find the section in the list Keyboards (Keyboards) and expand it.

If you see a device with a yellow exclamation point or the name "PS/2 Standard Keyboard," there is a problem. Right-click on your device and select Update driver. The best option is to choose Finding drivers on this computer and specify the path to the folder with drivers downloaded from the ASUS website.

Driver type	Where to find	Action
ATK Package	ASUS website	Mandatory setting for hotkeys
ASUS System Control Interface	Microsoft Store	Power and lighting control
Chipset Driver	ASUS website	Motherboard Chipset Update
Keyboard Driver	Device Manager	Reinstalling the standard driver

Pay special attention to the package ATK Package (or ATKACPI). It is this driver that is responsible for the operation of the function keys, including the backlight. Without it the buttons F1–F12 can work like regular multimedia buttons, ignoring laptop-specific functions.

⚠️ Attention: When reinstalling drivers through Device Manager, select “Remove device” and then restart your laptop. The system will automatically reinstall the drivers, which often corrects conflicts.

BIOS settings and disabling Fast Boot

If software methods do not help, you should look into the basic input/output system (BIOS/UEFI). Sometimes power saving settings prevent the backlight from working until Windows is fully loaded. You can disable the function in the BIOS Fast Boot, which may interfere with the initialization of peripheral devices.

To enter the BIOS, restart the laptop and immediately start pressing the key repeatedly F2 (or Del). Once the blue or gray BIOS menu appears, use the arrow keys on your keyboard to navigate. Go to the tab Advanced or Boot.

Find the parameter Fast Boot and set it to value Disabled. Also check your settings Keyboard Backlight or Backlight Control, if they are present. Make sure they are not disabled. Save changes with a keystroke F10 and confirm reboot.

In some cases, resetting the BIOS settings to factory settings may help. To do this, in the BIOS menu, find the option Load Optimized Defaults (Load optimal default values). This will return all settings, including backlight control, to their original state.

What to do if you can’t enter the BIOS?

If the laptop boots too quickly and you don't have time to press F2, go to Windows Settings -> Update & Security -> Recovery -> Special boot options -> Restart now. From the menu that appears, select Troubleshooting -> Advanced Settings -> UEFI Firmware Settings.

• 🔸 Go to BIOS by pressing F2 when turned on.
• 🔸 Disable Fast Boot in the download settings section.
• 🔸 Reset BIOS settings to factory defaults (Load Defaults).

Diagnosis of hardware failure

If none of the above methods worked, there is a high probability of a hardware malfunction. This could be a damaged keyboard cable, burnt-out LEDs, or a problem with the controller on the motherboard. In such cases, software intervention is powerless.

Especially often, such problems arise after the laptop is dropped or moisture gets inside the case. Even a small amount of liquid can oxidize the contacts responsible for the backlight, while the keyboard itself can continue to type normally. In this case, professional cleaning or replacement of the keyboard is required.

It is also worth checking whether the backlight is disabled through third-party software. Some power management or overclocking software may block the LEDs from working. Try removing recently installed hardware management utilities.

If your device is still under warranty, it is better to immediately contact an authorized service center ASUS. Describe the problem as “no keyboard backlight when hardware supported.”

• 🔹 Check if there have been any falls or moisture.
• 🔹 Uninstall third-party power management programs.
• 🔹 Contact the service center if the laptop is under warranty.

⚠️ Warning: Do not try to disassemble the keyboard yourself if you do not have experience. Thin cables are easy to damage, which will make the keyboard completely inoperable.

Sometimes the problem may be that the laptop is in Sleep or Hibernation mode with errors. Try turning off the laptop completely (not rebooting, but turning it off), unplug it, press the power button and hold it for 30 seconds (static reset). Then turn it on again and check the backlight.
