The F keys (F1 to F12) on your ASUS laptop provide quick access to a variety of functions, from adjusting screen brightness and volume to controlling media playback and accessing specific programs. However, by default, many ASUS laptops are configured to prioritize these multimedia functions over the standard F key commands. This means you often have to press the Fn key in combination with an F key to use it as intended in applications. This can be inconvenient and time-consuming, especially for professionals who frequently use F keys for software shortcuts and other productivity tasks. This guide provides a detailed walkthrough of how to configure your ASUS laptop to use the F keys directly, without requiring the Fn key.
Understanding the Fn Key and Function Key Behavior
The Fn key, short for “Function,” is a modifier key found on most laptops. When pressed in combination with another key, it activates a secondary function printed on that key. In the case of ASUS laptops, these secondary functions are usually multimedia controls assigned to the F keys.
The default behavior, where the multimedia functions are primary and F key commands are secondary, is often enabled to cater to general users who frequently adjust volume, brightness, and other system settings. However, this setup can be frustrating for those who rely on the standard F key functions in software applications, gaming, or development environments.
The core issue is that the default setting prioritizes system controls over traditional F key functionality.
Methods to Unlock Direct F Key Functionality on ASUS Laptops
There are several ways to change this behavior and regain direct control over your F keys. The most common and reliable method involves modifying the BIOS/UEFI settings. Other methods include using the ASUS Keyboard Hotkeys app or the MyASUS app if available. Let’s explore each method in detail.
Using the BIOS/UEFI Settings
The BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is a firmware interface that initializes the hardware during the boot process. It also allows you to configure various system settings, including the Fn key behavior.
Accessing the BIOS/UEFI Setup
To access the BIOS/UEFI setup, you typically need to press a specific key during the startup process. The key varies depending on your ASUS laptop model, but common keys include:
- Delete (Del)
- F2
- Esc
Power on or restart your ASUS laptop. Immediately after the ASUS logo appears, repeatedly press the appropriate key (Del, F2, or Esc). Keep pressing it until the BIOS/UEFI setup utility appears. If you miss the window, simply restart your laptop and try again.
Timing is crucial for successfully entering the BIOS/UEFI setup.
Navigating to the Fn Key Configuration Setting
Once inside the BIOS/UEFI setup, you’ll need to navigate to the section that controls the Fn key behavior. The exact location of this setting varies depending on the BIOS/UEFI version and your laptop model. Look for options such as:
- “Function Key Behavior”
- “Fn Key Lock”
- “Hotkey Mode”
- “Action Keys Mode”
Use the arrow keys to navigate through the menus. Look under categories such as “Advanced,” “Configuration,” “Boot,” or “System Configuration.” Refer to your laptop’s manual or ASUS support website if you’re having trouble locating the setting.
Carefully explore the BIOS/UEFI menus to find the Fn key setting.
Changing the Fn Key Behavior
Once you’ve found the setting, you’ll typically have two options:
- “Function Key First” (or similar wording): This option prioritizes the standard F key functions. Pressing an F key will directly trigger its default function (e.g., F5 for refresh), and you’ll need to press Fn + F key to access the multimedia function.
- “Multimedia Key First” (or similar wording): This is the default setting, where the multimedia functions are prioritized. You need to press Fn + F key to access the standard F key functions.
Select “Function Key First” (or the equivalent option) to enable direct F key functionality.
Selecting the correct option is key to achieving the desired behavior.
Saving Changes and Exiting the BIOS/UEFI
After changing the setting, you need to save the changes and exit the BIOS/UEFI setup. Look for an option such as “Save & Exit,” “Exit Saving Changes,” or “Save Changes and Reset.” Select this option and confirm your choice. Your laptop will restart, and the new Fn key behavior will be applied.
Always save changes before exiting the BIOS/UEFI setup.
Using the ASUS Keyboard Hotkeys App (If Available)
Some ASUS laptops come with a pre-installed application called “ASUS Keyboard Hotkeys” or a similar name. This app provides a user-friendly interface for configuring various keyboard settings, including the Fn key behavior.
Locating the ASUS Keyboard Hotkeys App
Search for the app in the Windows Start Menu. Type “ASUS Keyboard Hotkeys” or “Keyboard Hotkeys” in the search bar. If the app is installed, it will appear in the search results.
If you can’t find the app, it might not be installed on your laptop. In that case, you can try downloading it from the ASUS support website for your specific laptop model.
Check your laptop’s software for the Keyboard Hotkeys app.
Configuring the Fn Key Behavior in the App
Once you’ve opened the app, look for a setting related to the Fn key or function key behavior. The exact wording and layout of the app may vary depending on the version. You should find an option to switch between “Hotkeys” (multimedia functions as primary) and “Function Keys” (standard F key functions as primary). Select “Function Keys” to enable direct F key functionality. The changes should take effect immediately.
Simple interface makes configuring the Fn key behavior easier.
Using the MyASUS App (If Available)
The MyASUS app is another pre-installed application on many ASUS laptops. It provides access to various system settings, support resources, and troubleshooting tools. It may also include an option to configure the Fn key behavior.

By following the methods outlined in this guide, you can easily configure your laptop to prioritize the standard F key functions without requiring the Fn key. Whether you choose to modify the BIOS/UEFI settings or use the ASUS Keyboard Hotkeys or MyASUS app, the process is straightforward and can be completed in a few simple steps. Remember to troubleshoot any issues that might arise and consult your laptop’s manual or the ASUS support website for further assistance. With the F keys working as intended, you’ll be able to take full advantage of their functionality in your favorite applications and games.
Why are my F keys not working as expected on my ASUS laptop?
The primary reason your F keys might not be functioning as standard function keys (F1, F2, etc.) is due to the “Fn Lock” or “Function Key Lock” feature being enabled. ASUS laptops, by default, often prioritize multimedia functions like volume control, brightness adjustment, and keyboard backlight control over the traditional F key functions. This is intended for convenient access to commonly used settings directly from the keyboard.
Essentially, the Fn key becomes permanently pressed, activating the secondary function associated with each F key. When the Fn Lock is engaged, you need to press the Fn key in conjunction with the F keys to access their standard function. Disabling Fn Lock will restore the F keys to their default behavior, requiring you to use the Fn key to access the multimedia functions instead.
How do I disable or enable Fn Lock on my ASUS laptop?
The method for toggling Fn Lock varies depending on your ASUS laptop model. A common method is to press the “Fn” key and the “Esc” key simultaneously. This should enable or disable the Fn Lock, reversing the primary function of the F keys. Look for a small lock icon on the Esc key, which often indicates this functionality.
Another possibility is using the ASUS Keyboard Hotkeys or ASUS Utility software. Search for these applications in your Windows Start Menu. Within the software’s settings, there should be an option to configure the F key behavior and toggle Fn Lock on or off. If you don’t have this software, you might need to download and install it from the ASUS support website, specific to your laptop model.
Where can I find the ASUS Keyboard Hotkeys software for my specific laptop model?
The ASUS Keyboard Hotkeys software is usually available on the official ASUS support website. First, navigate to the ASUS website and locate the “Support” section.

Make sure to select the correct operating system version (e.g., Windows 10 64-bit, Windows 11 64-bit). Within the list of available drivers and utilities, you should find the “ASUS Keyboard Hotkeys” or similar named software. Download and install this software to manage your keyboard settings.
What if pressing Fn + Esc doesn’t disable Fn Lock on my ASUS laptop?
If the standard Fn + Esc method doesn’t work, there could be other configuration options affecting the F key behavior. One possibility is that the BIOS settings are overriding the default function key behavior. Reboot your laptop and enter the BIOS setup (usually by pressing Del, F2, or Esc key repeatedly during startup – the specific key is displayed briefly on the boot screen).
Within the BIOS settings, look for a setting related to “Function Key Behavior” or “Hot Key Mode.” This setting might be located under the “Advanced” or “Configuration” tab. Change the setting from “Hot Key Mode” to “Function Keys,” or a similar option that prioritizes the standard F key functions. Save the changes and exit the BIOS; your laptop should now boot with the F keys functioning as expected.
Can I customize the individual functions assigned to the F keys?
Yes, you can customize the functions assigned to the F keys on most ASUS laptops. While the ASUS Keyboard Hotkeys software allows for general control over the Fn Lock and default F key behavior, you can also use third-party keyboard mapping software for more granular customization.
These third-party applications allow you to remap individual F keys to perform specific actions, launch programs, or execute custom scripts. Be cautious when installing such software and always download from reputable sources. Additionally, explore Windows’ built-in keyboard shortcuts for customizing certain actions and assigning them to the F keys as needed.
Will updating the BIOS affect my F key settings?
Updating the BIOS can sometimes reset or alter existing settings, including the F key behavior. It’s always a good idea to back up your BIOS settings, if possible, before performing an update. After updating the BIOS, you may need to reconfigure the “Function Key Behavior” or “Hot Key Mode” within the BIOS settings, as described earlier.
Check your laptop’s documentation or the ASUS support website for specific instructions on how to properly update the BIOS and restore your desired settings. Improper BIOS updates can lead to system instability, so proceed with caution and follow the manufacturer’s recommendations carefully.
What if I’m still having issues with my F keys after trying all the suggested solutions?
If you’ve exhausted all the troubleshooting steps, including disabling Fn Lock, checking BIOS settings, and updating drivers, there might be a hardware issue with your keyboard or a deeper software conflict. In this case, contacting ASUS support directly is highly recommended.
Explain the steps you’ve already taken and provide your laptop’s model number. ASUS support can offer further assistance, including remote diagnostics, driver reinstallation instructions, or information about hardware repair options if necessary. It is also helpful to test with an external keyboard to determine if the issue is isolated to the built-in keyboard of your laptop.
