Keyboard backlight on laptops ASUS VivoBook is a useful feature for working in low-light conditions, but not all users know how to activate it correctly. Depending on the model (VivoBook S14/S15, Pro, Flip etc.) activation methods may differ: from simple hot keys to settings in the BIOS or proprietary software MyASUS. Often the problem lies not in the absence of a function, but in incorrect settings or an outdated driver.

In this article you will find step by step instructions for all popular models VivoBook, including solutions to common problems (for example, when the backlight does not respond to keys or flickers). We will also look at how to adjust the brightness and automatic shutdown so that the function works as conveniently as possible. If your model does not support backlighting, there is a list of alternative solutions at the end of the article.

1. Check whether your VivoBook model supports backlighting

Not all laptops ASUS VivoBook equipped with a backlit keyboard. To avoid wasting time on useless manipulations, first make sure that your model supports it. Typically this feature is available in series:

  • 💻 VivoBook Pro (N580, N705, etc.)
  • 💻 VivoBook S (S14/S15/S17, starting from 2018)
  • 💻 VivoBook Flip (TP412, TP470)
  • 💻 ZenBook (some models, for example UX425, UX534)

How to check exactly? Look into technical specifications on the official website ASUS or look at the keyboard: if there is a backlight, next to the key F3 or F4 there will be an icon 🌓 (a crescent with rays). You can also use the utility ASUS System Diagnosis (available in MyASUS), which will show a list of supported functions.

⚠️ Attention: On budget models VivoBook (For example, X515, E410) the keyboard backlight is physically absent. Attempts to enable it programmatically will only lead to errors in the system.
VivoBook model Backlight support Switching method
VivoBook S14 (S433) Yes (white) Hotkeys Fn + F3/F4
VivoBook Pro 15 (N580) Yes (RGB) Via MyASUS or BIOS
VivoBook Flip TP412 Yes (single color) Automatically in low light
VivoBook X515 No —

2. Method 1: Hotkeys - the fastest method

On most models VivoBook The backlight is turned on by a key combination. Usually this is:

  • 🔹 Fn + F3 - reduce brightness
  • 🔹 Fn + F4 — increase brightness
  • 🔹 Fn + Space — enable/disable (on some models)

If the combination doesn't work:

  1. Make sure function keys not blocked. Some laptops have a separate key Fn Lock (usually next to Esc).
  2. Try pressing Fn + Caps Lock - this may unlock additional features.
  3. Check if the driver is installed ATK Package (you can download it from the website ASUS in the support section for your model).
📊 What model of ASUS VivoBook do you have?
  • VivoBook S14/S15
  • VivoBook Pro
  • VivoBook Flip
  • Other backlit model
  • No backlight

On models VivoBook Pro N580VD And N705FD RGB backlight controlled via utility ASUS Aura Core, not hotkeys. Trying to use Fn + F3/F4 will only lead to a change in screen brightness.

3. Method 2: Setup via BIOS/UEFI

If the hotkeys do not work, the backlight may be disabled at the BIOS level. To activate it:

  1. Restart your laptop and click F2 or Del (depending on the model) to enter the BIOS.
  2. Go to section Advanced → System Configuration.
  3. Find the parameter Keyboard Backlight (or similar) and set the value Enabled.
  4. Save changes (F10) and reboot.

On some models (VivoBook S15 S533) the option may be hidden in the section Boot or Main. If there is no parameter, it means that the backlight is controlled only through Windows.

⚠️ Warning: Changing BIOS settings unnecessarily may cause your laptop to malfunction. If you are not confident in your actions, skip this method and try others.

Disconnect the charger (recommended for safety)

Write down current BIOS settings (take a photo)

Do not interrupt the process of saving changes

After rebooting, check the backlight operation -->

4. Method 3: Using the MyASUS utility

Proprietary software MyASUS Allows you to control the backlight on supported models. Download it from official website (Section "Drivers and Utilities" for your model). After installation:

  1. Open MyASUS and go to the section Hardware Settings.
  2. Select Keyboard Backlight.
  3. Adjust the brightness and operating mode (constant or timer).

For models with RGB lighting (VivoBook Pro N580) in MyASUS Additional effects available:

  • 🌈 Static - one color
  • 🌀 Breathing — smooth change in brightness
  • 🎨 Color Cycle — automatic color change
💡

If in MyASUS there is no backlit section, update the utility to the latest version. Older software versions may not support newer laptop models.

5. Method 4: Update Keyboard Drivers

A common reason for the backlight not working is outdated or missing drivers. To update them:

  1. Open Device Manager (Win + X → Device Manager).
  2. Expand section Keyboards.
  3. Right-click on the device (usually Standard PS/2 Keyboard or AT Keyboard) and select Update driver.
  4. Select Automatic search.

If Windows does not find updates, download drivers manually:

  • 🔗 Go to your model's support page on the website ASUS.
  • 🔍 Enter the name of the laptop in the search (for example, VivoBook S14 S433FA).
  • 📥 In the section Drivers and utilities find ATK Package And Keyboard Driver.

On models VivoBook Flip TP470 For the backlight to work correctly, you need to install ASUS Smart Gesture - even if you don't use a touchpad!

6. Method 5: Checking the light sensor

Some models VivoBook (For example, Flip TP412) automatically turn on the backlight in low light thanks to the built-in sensor. If the function doesn't work:

  • 🕯️ Check if the sensor (usually located next to the webcam) is covered.
  • 🔦 Try pointing a bright light at the laptop - the backlight should turn off.
  • 🔄 B MyASUS find the sensor settings and calibrate it.

If the sensor does not work correctly, you can disable it:

  1. Open Control Panel → Hardware and Sound → Power Options.
  2. Select What the power buttons do.
  3. Click Change settings that are currently unavailable.
  4. Uncheck Enable automatic keyboard backlighting (if any).
What to do if the light sensor is broken?

If the sensor is physically damaged (for example, after a laptop has been dropped), the backlight can be turned on manually via MyASUS or hotkeys. However, automatic mode will not work. In this case, we recommend contacting a service center ASUS to replace the sensor, since independent repairs may void the warranty.

7. Troubleshooting: Backlight flickering or not turning on

If the backlight behaves unstable, the reasons may be as follows:

Problem Possible reason Solution
Backlight flashes Driver conflict Uninstall the keyboard driver in Device Manager and reinstall it.
Doesn't respond to keys Missing ATK Package Download and install the utility from the website ASUS.
Works only on charging Power settings B Control Panel → Power Options select scheme High performance.

If none of the methods help, try resetting the BIOS settings to factory defaults (Load Default Settings in the BIOS) or roll back the system to a restore point when the backlight was working.

💡

On models VivoBook Pro with RGB lighting, blinking may be due to a utility conflict ASUS Aura Core And Armoury Crate. Uninstall one of the programs and reinstall it.

8. Alternative solutions if there is no backlight

If your model VivoBook does not support backlighting, consider the following options:

  • 🔦 External USB backlight: LED strips connected to the USB port (for example, Havit KV395).
  • 💡 Table lamp with adjustable light: for example, Xiaomi Mi LED Desk Lamp.
  • 🖥️ Keyboard overlays with LEDs: sold at AliExpress or in computer stores.
  • 🔄 Replacing the keyboard: On some models you can install a backlit keyboard from another version VivoBook (compatibility check required).

Before purchasing an external light, make sure it is compatible with your laptop. For example, USB devices may conflict with ports on VivoBook X515 due to limited power.
