Keyboard backlight on ASUS VivoBook 15: how to turn it on in 3 minutes (all methods)

Keyboard backlight on ASUS VivoBook 15 is a useful function for working in the dark, but not all users know how to activate it correctly. Often the problem lies not in a malfunction, but in a simple ignorance of key combinations or hidden settings. For example, on models VivoBook 15 X512 And S533 the backlight can be turned off by default, and in F512 — require driver updates.

In this article we will look at all working methods for turning on the backlight - from standard hotkeys to manual configuration via BIOS and utility MyASUS. You will also learn why the keyboard may not light up even after correct actions, and how to fix it. If your laptop belongs to the series VivoBook 15 (regardless of the year of manufacture), here you will find a solution for your model.

1. Check the backlight support of your VivoBook 15 model

Before attempting to turn on the backlight, make sure that your ASUS VivoBook 15 supports her. Not all modifications are equipped with this function - for example, budget versions X512DA or F512DA are often produced without backlighting, while S533 or X515 they have it.

How to check:

• 🔍 Search by model: enter the full name of your laptop (for example, ASUS VivoBook 15 X512FL) on the official ASUS website in the "Specifications" section. Look for the item Keyboard Backlight.
• 💡 External inspection: The backlight is usually visible through the gaps between the keys when the laptop is turned off (if there is one, you will notice a faint glow in bright light).
• 📄 Documentation: check the box or user manual - there may be a mark there Illuminated Keyboard.

If your model does not support backlighting, further actions are pointless. In this case, consider purchasing external lighting with USB connection (for example, from brands Havit or Razer).

2. Standard method: hot keys to turn on the backlight

On most models VivoBook 15 The backlight is controlled by a key combination. Usually this is:

• 🔑 Fn + F3 or Fn + F4 — increases/decreases brightness (there should be a 💡 icon on the keys).
• 🔑 Fn + Space — turns on/off the backlight (on some models, for example, X515).
• 🔑 Fn + Up/Down Arrow — brightness adjustment (rare, but found on older versions).

If the keys do not work:

1. Make sure Fn not locked (some laptops have a separate key Fn Lock).
2. Try pressing Fn + Esc - this can unlock the function keys.
3. Restart your laptop - sometimes the backlight freezes after a Windows update.

Important! On models VivoBook 15 with processors AMD Ryzen (For example, X512DA) the backlight can be controlled through the utility ASUS Armoury Crate, not hotkeys.

3. Setting the backlight via BIOS/UEFI

If the hotkeys do not work, the backlight may be disabled at the BIOS level. This method is suitable for models VivoBook 15 S533, X515 and others with support Advanced Mode in BIOS.

Step by step instructions:

1. Turn off your laptop.
2. Clamp F2 and turn on the power (do not release F2until the BIOS menu appears).
3. Go to section Advanced → Keyboard Backlight (name may vary, look for mention Keyboard or LED).
4. Set the parameter to Enabled.
5. Save changes (F10) and reboot.

⚠️ Attention! Not all BIOS versions have this option. If you don't find the section Keyboard Backlight, do not change other settings - this may cause the laptop to malfunction.

What to do if the BIOS does not save settings?

If after saving (F10) and reboot the backlight does not work, reset the BIOS to factory settings (Load Default Settings). Then repeat the steps. If the problem persists, update the BIOS via the official ASUS website.

4. Backlight control via MyASUS utility

• 📥 Check if the package is installed ATK Package (you can download it from the ASUS website in the drivers section).

5. Update drivers and software for correct operation of the backlight
