Most Asus Vivobook models include a backlit keyboard you can control with Fn shortcuts and MyASUS settings for brightness and behavior.
Typing on an Asus Vivobook in a dark room feels far easier when the backlit keyboard works as it should. At the same time, this feature can be confusing because not every Vivobook has it, and the controls change slightly between generations. This guide walks you through checking whether your Vivobook includes a backlit keyboard, how to turn it on, ways to adjust the light, and what to do when the keys refuse to glow.
Backlit Keyboard On Asus Vivobook Models: Quick Check
Before you try any fixes, you need to confirm whether your particular Vivobook model actually includes a backlit keyboard. Many variants share the same chassis, so two laptops that look almost identical can differ in this one feature.
Check The Function Row For A Light Icon
Most Vivobook models that ship with a backlit keyboard place a tiny keyboard-with-rays icon somewhere on the function row. It often sits on F7, and on some models the brightness up and down controls sit on F3 and F4. If you see that icon on any of those buttons, your keyboard was designed to light up.
- Look For The Backlight Symbol — Scan the top row of keys for a small keyboard outline with light rays or a glowing bar above it.
- Press Fn Plus That Button — Hold the Fn button and tap the function row button with the light symbol a few times to see if the backlight wakes up.
- Try F3 And F4 As Well — If nothing happens with Fn+F7, try Fn+F3 and Fn+F4 because some layouts split brightness down and up across those keys.
Confirm Backlit Keyboard In The Official Specs
Asus lists whether a particular Vivobook has a backlit keyboard in the specification sheet for that exact model code. The model number usually appears on a label under the laptop or inside MyASUS. Once you have that code, you can look up the spec sheet on the Asus help site.
- Find The Full Model Code — Flip the laptop over and check the sticker near the hinge, or open MyASUS and read the product name on the Home page.
- Open The Online Spec Sheet — Search that model code on the Asus product page and look for a line that mentions a backlit chiclet keyboard or similar wording.
- Compare Retail Listings — If you still have the store listing or box, look for wording such as “backlit keyboard” in the feature rundown.
When the spec sheet makes no mention of a backlit keyboard and you cannot find a light icon on the keycaps, software tweaks will not add the feature. In that case, an external USB keyboard with backlighting or a small LED desk light is your most realistic route.
How To Turn On Backlit Keyboard On Asus Vivobook
Once you know your Vivobook includes backlighting, turning it on usually takes only a few keystrokes. The exact combination depends on the keyboard layout and the generation of the laptop, but the steps follow the same pattern.
Use Fn Shortcuts To Toggle The Backlight
The primary control for an Asus Vivobook backlit keyboard sits in the function row. On many current models, you turn the light on and step through brightness levels with Fn + F7. Some layouts instead use Fn + F4 to raise brightness and Fn + F3 to lower it.
- Hold Fn And Tap The Light Button — Press and hold Fn, then tap the button that carries the keyboard light symbol once or several times.
- Cycle Through Brightness Levels — Keep tapping to rotate through off, low, medium, and high brightness where available.
- Test In A Dim Room — Room lighting can make a low setting hard to see, so test the keys in a darker space to confirm the backlight level.
Some Vivobook generations use so-called “hotkeys” where the F1–F12 row controls features by default. On those layouts you might tap F7 with the backlight symbol on its own, or switch a toggle in MyASUS so the top row acts as classic function buttons instead.
Adjust Backlight Settings In MyASUS
Many current Vivobook models expose extra keyboard backlight options in the MyASUS application. This includes automatic dimming, timeout controls, and behavior on battery power.
- Open MyASUS — Launch MyASUS from the Start menu, then move to the Device Settings or Customization section.
- Find Keyboard Backlight Options — Look for a Keyboard or Lighting tab that offers brightness sliders, timeout settings, or an on/off toggle.
- Set Timeout And Brightness — Choose how bright the backlight should be and how quickly it should fade when you stop typing.
- Check Battery Behavior — Some Vivobooks cut the backlight when the battery drops under a threshold; if you want the light on even at lower charge levels, change that setting here.
On select Vivobook models with colored lighting, MyASUS may also offer simple effects or color choices. Gaming-oriented lines lean more on Armoury Crate or Aura Sync for that side, while mainstream Vivobooks usually keep things modest with white light only.
Turn On Backlight Options In Windows Settings
Some Vivobook models add a few keyboard light controls to Windows itself. They do not replace the Fn shortcuts, yet they can fine-tune brightness and timeout.
- Open Windows Settings — Press Windows+I, go to System, and check whether a Keyboard or Backlight page appears for your device.
- Review Power Options — Through Control Panel > Power Options, avoid custom plans that disable lighting while on battery.
If these menus never show any backlight options, rely on MyASUS and the function row instead.
Common Backlit Keyboard Shortcuts And Modes On Vivobook
Asus tweaks the layout slightly between series, but most Vivobook laptops follow a familiar set of shortcuts and modes for the backlit keyboard. Using them well can make the light feel natural instead of distracting.
| Shortcut | Action | Notes |
|---|---|---|
| Fn + F7 | Toggle keyboard backlight | Common on recent Vivobooks; cycles through brightness levels. |
| Fn + F3 | Lower backlight brightness | Used on some layouts to dim or turn off the lighting. |
| Fn + F4 | Raise backlight brightness | Pairs with Fn+F3 on models that split brightness down and up. |
| MyASUS timeout setting | Set idle fade delay | Controls how many seconds the light stays on when you stop typing. |
| MyASUS auto-brighten | Backlight reacts to room light | Turns the light on when the room gets darker on supported models. |
The exact mix of entries in the table above depends on your firmware and software version. For reference, Asus documents the function-row behavior in its official backlit keyboard FAQ, and that wording may match what you see in MyASUS.
Troubleshooting Backlit Keyboard On Asus Vivobook
If your Asus Vivobook backlit keyboard will not turn on, feels stuck at one brightness level, or turns off at odd times, there is usually a clear reason. Work through these checks from the simplest ones to the deeper fixes and see where the light comes back.
Start With Basic Checks
- Charge Or Plug In The Laptop — Many models dim or disable the keyboard light on low battery to conserve power, so plug in and test again.
- Test In A Dark Room — On a low brightness level, the backlight can be hard to notice in bright daylight.
- Press The Fn Button Firmly — A stuck Fn button or slightly shifted finger can make it seem like the backlight shortcut fails.
- Restart Windows — A reboot refreshes the firmware modules that handle keyboard lighting and sometimes clears stuck states.
If the keyboard briefly flashes during boot but then stays dark inside Windows, the hardware probably still works and the problem lies with software layers on top of it.
Check MyASUS And Power Settings
Next, you want to be sure that no software setting disables the light on purpose. MyASUS and your power plan can both cut keyboard brightness under certain conditions.
- Open MyASUS Device Settings — Under Device Settings or Customization, look for a Keyboard or Lighting section with toggles and sliders.
- Disable Aggressive Timeout — If the light switches off after only a few seconds, extend the idle timeout so you can see whether it actually turns on.
- Relax Battery Saving Rules — Raise the battery percentage at which the backlight turns off, or let it stay active on battery at all charge levels.
- Review Power Plan Settings — In Power Options, avoid plans that disable display and keyboard lighting too quickly, especially when running on battery.
If those toggles all look fine and the backlit keyboard still ignores the Fn shortcut, it is time to refresh the Asus software that interprets those button presses.
Update Asus System Drivers
Backlight control on an Asus Vivobook relies on both firmware and Windows drivers. When those components fall out of date, the system might not react to your shortcuts even if the hardware is in good shape.
- Download Drivers From The Model Page — Visit the Asus product page for your exact Vivobook model and open the Drivers & Tools section.
- Install System Control Interface Or ATK Package — Look for entries related to hotkeys, system control, or keyboard and install the newest versions.
- Run Windows Update — Let Windows fetch hardware updates as well, then restart and try the Fn shortcuts again.
If the backlit keyboard still stays dark, the next step is to reset the embedded controller, which handles power and some keyboard functions on many laptops.
Reset The Embedded Controller (EC)
Asus documents a hardware reset procedure that clears the embedded controller when low-level functions misbehave. The steps vary slightly between laptops, but the pattern stays similar.
- Shut Down The Laptop — Turn the Vivobook off completely instead of letting it sleep.
- Unplug The Charger — Remove the power adapter and any connected docks or USB hubs.
- Hold The Power Button — Press and hold the power button for around 40 seconds to discharge residual power from the board.
- Reconnect And Boot — Plug the adapter back in, power on, and test the Fn backlight shortcut while Windows loads.
On some Vivobook designs, Asus recommends slightly different timings for this reset or an extra step in the BIOS menu, which you can find in the dedicated keyboard backlight troubleshooting guide. If a full EC reset still makes no difference, you may be dealing with a damaged cable, a faulty backlight strip, or a replacement keyboard that does not match the original spec.
When Your Vivobook Has No Backlit Keyboard
Plenty of Asus Vivobook configurations ship without backlighting even when photos on store listings sometimes show glowing keys. In these cases, you can tap Fn shortcuts all day and nothing will happen, because there is no light behind the keycaps.
Signs That Your Keyboard Is Not Backlit
- No Light Icon On The Keys — The function row lacks a keyboard-with-rays symbol, even when other icons such as volume and brightness appear.
- Spec Sheet Says Standard Keyboard — The product page lists only “chiclet keyboard” without the word backlit anywhere.
- MyASUS Lacks Lighting Options — Device settings show no tabs or sliders that mention keyboard illumination.
If all three clues line up, your Vivobook almost certainly uses a non-backlit keyboard assembly. This is not something a firmware update can change, because the LED layer and cable are physically missing.
Practical Alternatives To A Built-In Backlight
When your Vivobook keyboard cannot light up at all, small tweaks still make typing in dim rooms less tiring.
- Add A USB Backlit Keyboard — A low-profile external keyboard with white lighting can plug into a spare USB port.
- Use A Small Desk Lamp — A narrow-beam LED lamp aimed across the keys gives clear legends without washing out the screen.
- Tweak Display Brightness And Theme — A modest brightness level and a light app theme often make dark letter legends easier to read.
When shopping for accessories, double-check that any replacement keyboard or new laptop you consider lists a backlit keyboard in the official specs.
Care Tips For Asus Vivobook Backlit Keyboard
A backlit keyboard feels great on day one, and a bit of care helps it stay readable and responsive across years of typing. These habits keep the light layer and switch mechanisms in good health.
- Keep Liquids Away From The Keys — Small spills can stain or short the light layer even if the laptop survives the incident.
- Clean With A Soft Cloth — A lightly damp microfiber cloth and gentle pressure are enough for most fingerprints and dust.
- Avoid Harsh Cleaners — Strong chemicals can cloud the letter legends and make the lighting look blotchy.
- Watch Heat And Direct Sunlight — Leaving the Vivobook in a hot car or under direct sun for long periods is rough on the plastic and the LED strip.
- Do Not Pry Keycaps Off — Popping caps off by hand can damage the scissor mechanism or tear the light diffuser under the keys.
Backlight brightness also affects wear over time. A high setting on a plugged-in laptop looks nice, yet it pushes the LED layer harder. If you often work in dim rooms, a middle setting usually gives a comfortable balance between visibility and longevity.
Asus Vivobook Backlit Keyboard Checklist
This final checklist collects the main steps for dealing with a backlit keyboard Asus Vivobook owner is likely to face, from first setup to stubborn issues.
- Confirm The Feature — Check the function row, spec sheet, and MyASUS to see whether your exact Vivobook model includes a backlit keyboard.
- Learn The Shortcuts — Practice the Fn combination (often Fn+F7 or Fn+F3/F4) until adjusting brightness feels automatic.
- Tune MyASUS Settings — Set a comfortable brightness level, idle timeout, and battery behavior for the keyboard light.
- Review Power Plans — Make sure your chosen power plan does not disable lighting too aggressively on battery.
- Update Firmware And Drivers — Keep Asus hotkey and system control drivers current so the Fn shortcuts keep working.
- Use EC Reset When Needed — If the light fails after updates or long sleep sessions, perform a careful embedded controller reset.
- Choose Alternatives Smartly — If your Vivobook lacks a backlit keyboard entirely, pick a reliable external keyboard or lamp instead of chasing impossible software fixes.
With those steps in hand, a backlit keyboard Asus Vivobook moves from frustration to comfort. You get keys you can see in the dark, lighting behavior that matches how you work, and a clear plan for situations where the glow does not show up on cue.
