Introduction
It is annoying to attempt to work on a dark room without a keyboard that is backlit. You miss keys. You type slower. You get annoyed fast.
Lots of Asus laptops sold in the US have a backlight on the keyboard but which method of activating it may vary depending on the model. There are those that use MyASUS, others that use Armoury Crate and those that use only the function keys. Many of the online guides have provided information on only one type and omitted important information.
This manual concentrates on US consumers and unites all of it. It shows you how to:
- Enquire whether your Asus laptop can even have a keyboard light.
- Switch the asus laptop keyboard light off and on.
- Tilter light and on certain models, the sleep time.
- Change ROG and TUF RGB keyboard colors.
- Insert solutions to frequent problems where there is no light.
All of the following is dedicated to the basic Windows 10 and 11 configurations using the US keyboards layouts.
First test: does your Asus laptop have even a keyboard light?
The first thing that you need to note before you spend time on settings and drivers is to ensure that you bought a laptop that has a back-lit keyboard.
Find an icon of a Asus laptop keyboard light.
Learning the easy way is by learning the keys.
Consider the first row of your keyboard F1- F12. You are looking after the icon of a small keyboard with the rays of light or a small sun right over it. There are other times that the icon is a keyboard with small rays emanating out of the top. It may be a symbol of the sun that has been drew above a keyboard shape.

Whenever you have any of them on the functional key, then you can be very sure that your Asus laptop keyboard light.
In case no F1-F12 keys have a keyboard or light symbol, that is a good indication that your model does not have back lighting.
Test the appearance of the important legends.
Backlit keys normally have characters and icons that appear transparent. The printing is made in a way that it allows the light to penetrate through the print. These legends appear a little gray or a little soft when the laptop is not in use than on a low-quality non-backlit keyboard.
The letters look like solid thick paint upon non-backlit keyboards. Through them you will not see any ray of bright sunshine.
This is not an ideal test but it aids in affirming what you observe in the function row.
Consult the official specifications of US models.
In case you are not certain, find out the model you are interested in.
There will be a model on the sticker on the bottom or the box:
- Asus ZenBook UX425EA
- Asus VivoBook 15 F515EA
- Asus ROG Strix G15 G513
- Asus TUF Gaming F15 FX507
Enter that entire name in your search engine with the addition of the word specs. Visit the Asus US site or the listing of a US retailer like the Best Buy, Costco, Walmart or Amazon.
In the specs, you find the terms like backlit chiclet keyboard,RGB keyboard, single-zone RGB keyboard or per-key RGB. When this is written on your laptop, then you have Asus laptop keyboard light.
When you simply see a chiclet keyboard and nothing about backlit was mentioned then there is a high probability that the keyboard does not have a light.
A note on Asus Chromebooks
In the US, some Asus Chromebooks are sold with the backlit keyboards. Others do not. In the case of these, the product page is the ultimate solution. Under the keyboard or input, you will find the option of backlit keyboard. Chromebook shortcuts are slightly different as well which we shall touch upon later.
In case you fail to see any backlighting display on the icons or the specifications, then you can presume that it is not supported by your model. Then, there is no software or registry trick that can make a keyboard light.
Asus laptop Keyboard lighting- How to (quick answer)?
The brief one that many are searching is this one.
The Asus laptop keyboard light can be switched on by simply pressing the Fn key and the function key bearing the keyboard-with-light icon (F7, F3 or F4). Repeat the process by pressing it a couple of times, and in the process, keep pressing Fn to go through levels of brightness until the asus laptop keyboard light becomes bright.
We shall now proceed to a more detailed account of that, and discuss frequent variations.
Action plan: enabling the backlight of the keyboard.
Locate the appropriate functional key.
The first step is to scan your F1- F12 keys.
Look for one of the following:
- An outline of a small keyboard having rays above it.
- An icon of a keyboard with the symbol of a tiny sun or star.
- In extreme situations, an A having light rays.
The keys that are common on the US Asus laptops are:
- F3 and F4 to decrease and increase the brightness.
- F7 being a single cycle brightness key.
The key can vary, particularly between ROG, TUF, ZenBook and VivoBook. Under no circumstances should one follow any generic direction despite the printed icon.
Press Fn key in combination with the backlight key.
Once you have the knowledge of which of the two backlight control keys to use, switch it on.
Press Fn at the lower left hand corner of the key board. Pressing the backlight function key and keeping Fn together once. Check the keys to determine whether they are glowing.

When you do not see anything change, continue holding Fn and press backlight key several times. The majority of the Asus models switch off to low, medium and high brightness followed by switching back to off.
When you are in a sunny office or sitting by a window, then the low setting can be invisible. Switch off the room lights or place your hand to close the keyboard and see whether a dim glow is present.
Check Fn Lock in case there is no response.
There is also an Fn Lock in some Asus laptops. Under some circumstances, you do not need the Fn key when you are on. You can never do without Fn in other modes.
In case of no result of pressing Fn and the key of the backlight, press Fn + Esc once. This enables Fn Lock on a number of models. Thereupon revisit the backlight key finger and press with Fn. It can then just begin to reply.
When your Esc key contains a small padlock icon indicating your key is an Fn Lock, then there is a high likelihood that your laptop is subject to this.
Imagine that my Asus laptop had not had a keyboard light?
In case your laptop was shipped without a backlit keyboard, it will not be added anywhere in Windows, MyASUS and BIOS. The keys do not have any LEDs and the motherboard may not have a connector to take a backlight cable.
Occasionally some fans and repair experts will install a backlit keyboard of the same model. This is complex. You will require a perfect match in parts and have to take down the top case. You also run the risk of rescinding any warranty that may still exist.
By far, external alternatives make more sense to most users in the US. A sleek USB or Bluetooth keyboard that has its back light is good on a table. You can use a small USB light or clip-on lamp which assists you to see your built-in keyboard when you are on the go.
Conclusion
A functioning Asus laptop keyboard light is a huge difference in the comfort with which you can use your computer during the real life experiences such as during late night study sessions or during long flights. The problem is that Asus operates various shortcuts and software in their ZenBook, VivoBook, ROG, TUF, and Chromebook series, that is why so many people are lost the first time they want to turn it on.
The Asus laptop keyboard light is simple to control once you are aware of what to use, a keyboard-with-light icon on the function row, the Fn key shortcuts and in gaming models, the Armoury Crate lighting controls. It has a few clicks in turning it on, setting the appropriate brightness, creating a time to shut, and even customizing colors on any RGB model.
