Why is the fn key not working on an Acer, Compaq, Apple, DELL, Fujitsu, eMachines, Lenovo, Fujitsu-Siemens, HP, Bell, LG, MSI, Roverbook, Packard, Sony, Panasonic, Samsung, or Toshiba laptop.
All the models described above, although they have some differences, the reasons why the fn key does not work are almost always the same.
The only exception is in the names of the drivers, although they themselves are not the main source of the problem (stopped or stuck).
So in Samsung it is "Control Center", in HP "HP Quick Launch Buttons", ASUS - "ATK Hotkey" and Toshiba - Hotkey utility.
The fn key is present only in laptops. It was created to simplify the work (quick call of components).
With this button, you can usually turn on or turn off bluetooth, Wi-Fi, reduce or increase the brightness of the screen.
Also generally turn off, call email, turn on numeric keypad and a few more functions depending on the model of netbook or laptop.
In general, there are several reasons why the Fn key does not work on a laptop. The controller is responsible for its work - "Keyboard Controller". What can be done to fix the problem.
The first step is to find out the type of damage: mechanical (dust, liquid) or systemic (damage or lack of drivers.)
In any case, all the functions that the fn key combination provides with others can be enabled in another way - this is just a matter of convenience.
So, in case of mechanical damage to the fn key. You can find out more details by clicking on the link. In the case of a systemic violation, install .
Also note that there is a possibility that the fn key may not work at all. For example, you bought a laptop designed for a 64-bit system, and installed 32. Lately, such problems have often arisen. This is especially true for bluetooth.
There are no drivers for 32 (86) operating systems on the official websites of manufacturers and that's it - period!
No matter how much you look for it, you won’t find it; you won’t be able to write it yourself either. You have to refuse these amenities or install 64. In laptops: asus, acer, toshiba and samsung this happens often.
fn key driver
On the driver for the fn key, I want to dwell especially. If you want to install a new one, and this is often the reason why this button does not work, then download it only for your model and from the manufacturer's website.
To do this, do the following, go to the site (in the search write: support = laptop name =), specify the model and go to the page with drivers for the keyboard (controllers). You can even download everything, it won't hurt, you just update them.
By the way, there is one unsurpassed way. It always works 100%.
You can also enter the "device manager", select "keyboard" and if there is a disk with drivers from the manufacturer, update them from there.
There is also the possibility of updating drivers via the Internet, but this method is not very effective.
The search is based on Microsoft, and (not the manufacturer) and usually ends in vain.
Program for the fn key
The Internet offers a program for the fn key Easy Display Manager. I just don't trust them.
Once I used such a creation to install latest versions drivers, as a result, I had to reinstall the operating system.
The Fn key refers to the system components of the keyboard, utilities (drivers) are responsible for its operation, and only the only ones of their kind (depending on the laptop model).
Therefore, you need to look for them only at the office. manufacturers' websites, only then you can resume the operation of the fn key combination with others.
The functionality of the Fn key is obvious to many. In combination with this button, quick actions are performed on many portable computers, including Samsung laptops. By holding Fn with shortcut keys, you can turn adapters on and off wireless network, touchpad, adjust many settings, such as screen brightness or sound volume, and switch the device to another operating mode. Disabling this key or, conversely, constantly turning it on can obviously interfere with working with a laptop. In this article, we will tell you how to enable or disable this key.

The laptop keyboard is one of the most important elements of the computer; it contains various keys with which you can call up certain settings menus. As well as enabling and disabling various functions, one of these is the Fn (function) button. Using this key in combination with any other, you can reduce the brightness of the screen, lower or increase the sound on the laptop, turn on Wi-Fi. On many popular laptop models, this button is disabled by default. From this material, you will learn how to enable fn on a Samsung laptop, and also for what reasons, in addition to a physical malfunction, this key may not work.
fn button on samsung laptop not working
On some Samsung laptop models, there is no access to fine-tuning your personal computer through the operating system. They can be implemented only by pressing the "hot" keys on the keyboard. In case fn does not work on a Samsung laptop, you will find yourself in a very difficult situation. A similar phenomenon can rarely be seen, because not all developers personal computers the most important system keys are placed on the keyboard. This is done in order to protect the user from problems associated with the functioning of the PC when the keyboard is physically exposed to water.
This article will take a detailed look at what to do if the fn button on a Samsung laptop does not work. We will also figure out how to enable and disable this key when the keyboard is working properly. And find out for what reasons the fn button does not work on your laptop.
Reasons why it doesn't work
One of the most common fn button malfunction issues is a physical malfunction due to water contacting the keyboard. When liquid gets on the text input device, an oxide film is created on the tracks of the board with a further violation of one of the matrices. As a result, current does not flow through them, and the fn button on a Samsung laptop does not work. Often the track on which the computer function key is located fails, since it is associated with many keyboard buttons.
Another reason is that the fn key is disabled by default and requires the user to press a combination of buttons to activate it, most commonly Fn + NumLock. This reason can also include the deactivated system key mode in the BIOS environment.
The third and final reason may be a dirty keyboard. If debris gets under the keys, blocking their pressing may occur. This happens because the rubberized nozzle on the button is not pressed inward and does not come into contact with the device board.
These are some of the most common reasons why the fn button on a Samsung laptop is not working.
How to enable the Fn key on a Samsung laptop
First of all, it should be noted that the reasons why the key does not work can be different. The main ones have been described above. Before trying to turn on Fn, you should understand what kind of problem you have. If water has not come into contact with the keyboard, try the instructions below one by one to turn it on.
Let's start with the most basic, namely the inclusion of the "Fn" key in the BIOS environment.

Conclusion
In this article, we have examined in detail possible reasons failure of the keyboard on Samsung laptops, as well as the reasons why the fn button on a Samsung laptop does not work. And also figured out how to turn it on and off different ways. If the cause of the malfunction is physical, contact the service center.
On laptops, there is a special Fn function key that allows you to use special hotkeys, such as turn on / off the Wi-Fi device, increase / decrease the volume, change the screen brightness and much more. Depending on the operating mode, accessibility features are activated by pressing fn keys and one of the standard keys F1-F12, or without pressing the Fn key. In this case, the functions of the F1-F12 keys will work in combination with pressing the special Fn key.
Often after reinstallation operating system or after windows updates the Fn key stops working. There may be several reasons, which also depend on the manufacturer and even the specific laptop model. In general, there are only three main reasons why the Fn key stops working:
- The necessary drivers or utilities are missing on the user's computer.
- Functioning of the Fn key requires a running utility that has been removed from autorun.
- The Fn key settings have been changed in the computer's BIOS by the user manually or by updating the BIOS or resetting it.
The first reason is most often the root cause when there are problems with the special function key. Since various utilities and drivers affect the full-fledged operation of the key, depending on the laptop manufacturer, we will consider for each manufacturer which official utilities and drivers need to be installed or updated.
ASUS laptops
For normal operation of the keyboard, you need to download and install software and a set of drivers - ATKPackege for your laptop model and operating system version from the official site asus.com. At the same time, after installing the software, the hcontrol.exe utility should be in the autorun, which will open when Windows starts.
Additionally update all available chipset drivers motherboard laptop. Usually, after installing the software and drivers, a reboot is required, after which you can check the operation of the Fn key.
HP laptops
The HP Notebook Family requires the following software products to be installed from support.hp.com:
- HP Software Framework
- HP On-Screen Display
- HP Quick Launch
- HP Unified Extensible Firmware Interface (UEFI)
All of these products must be downloaded from the official website, and you must specify your computer model and operating system version. If on the website for your laptop you do not find a suitable Windows version, then you should choose the earliest edition and be sure that its bit depth (x86 or 64-bit) matches that installed on the laptop.
Acer laptops
For Acer laptops, you need to go to the support section on the official acer.com website and download the following components:
- Launch Manager Utility
- Motherboard chipset driver.
After installing or updating software, make sure that the Launch Manager utility starts automatically when you log on to Windows. In some cases, the Fn key will help restore the installation of the Acer Power Manager program.
Lenovo laptops
On the Lenovo laptops the set of software will be different, so to be sure, you should install all the necessary and available software for your laptop model from support.lenovo.com. As a rule, for most modern models it is enough to install the following set of utilities:
- Hotkey Features Integration for Windows
- Lenovo Energy Management
- Lenovo OnScreen Display Utility
- Advanced Configuration and Power Management Interface Driver
At the same time, if only certain key combinations do not work for you, for example, Fn + F5, Fn + F7, then in many cases installing drivers for the wireless network and the Bluetooth network helps.
Dell laptops
The Dell Notebook Customer Support site dell.com/support requires the following software products to be downloaded:
- Dell QuickSet Application
- Dell Power Manager Lite Application
- Dell Foundation Services Application
Older laptops may need to install additional Dell Function Keys.
Sony laptops
The following components must be downloaded and installed in order for the function keys to work properly:
- Sony Firmware Extension Parser Driver
- Sony Shared Library
- Sony Notebook Utilities
You can do this on the official website sony.ru/support, where you should also indicate the laptop model and select the version of the operating system installed on it.
Also, on many laptop models, regardless of manufacturer, the Fn key can be switched to a different mode of operation, so go to the BIOS of your laptop and go to the Advanced or System Configuration section, then you should find one of the items associated with the Fn key:
- Action Key Mode
- Function Key Behavior
- Hot Key Mode
- Fn and Ctrl Key Swap
You may have only one of these items in your BIOS, which switches the mode of operation of the F1-F12 function keys with or without pressing the Fn key. The Fn and Ctrl Key Swap item in the BIOS of Lenovo laptops allows you to use Fn as the Ctrl key and vice versa, Ctrl key will perform the Fn function. That is, as if the keys are interchanged. Therefore, try to switch the mode of operation of the function keys by setting the appropriate value to Enabled or Disabled. Saving changes in the BIOS is done by pressing the F10 key, after booting the system you can check the performance special functions laptop.
Most laptops have a separate Fn key, which, in combination with the keys in the top row of the keyboard (F1 - F12), usually performs laptop-specific actions (turning Wi-Fi on and off, changing the screen brightness, etc.), or vice versa - without it presses trigger these actions, and with a press, the functions of the F1-F12 keys. A common problem for laptop owners, especially after a system update or manual installation Windows 10, 8 and Windows 7 - that the Fn key does not work.
This guide details common reasons why the Fn key may not work, as well as ways to fix this situation in Windows for common brands of laptops - Asus, HP, Acer, Lenovo, Dell and, most interestingly, Sony Vaio (if you some other brand, you can ask a question in the comments, I think I can help).
Reasons why the Fn key does not work on a laptop
To begin with, about the main reasons why Fn may not function on the laptop keyboard. As a rule, the problem is encountered after Windows installation(or reinstallation), but not always - the same situation may occur after disabling programs at startup or after some BIOS settings (UEFI).
In the vast majority of cases, the situation with a non-working Fn is caused by the following reasons
- Notebook manufacturer-specific drivers and software are not installed to make the function keys work - especially if you reinstalled Windows and then used the driver pack to install the drivers. It is also possible that there are drivers, for example, only for Windows 7, and you installed Windows 10 (possible solutions will be described in the troubleshooting section).
- The Fn key requires the manufacturer's utility process to be running, but this program has been removed from Windows startup.
- The behavior of the Fn key has been changed in the BIOS (UEFI) of the laptop - some laptops allow you to change the Fn settings in the BIOS, they can also change when you reset the BIOS.
Most often, point 1 is the cause, but then we will consider all the options for each of the above brands of laptops and possible scenarios for fixing the problem.
Fn key on Asus laptop
The ATKPackage - ATKACPI driver and hotkey-related utilities, available for download on the Asus official website, is responsible for the operation of the Fn key on Asus laptops. At the same time, in addition to the installed components, the hcontrol.exe utility should be in autoload (it is added to autoload automatically when ATKPackage is installed).
How to Download Fn Key and Function Key Drivers for Asus Laptop
After that, you may need to restart the laptop and, if everything went well, you will see that the Fn key on your laptop is working. If something went wrong, below is a section about common problems when fixing non-working function keys.
HP laptops
For full operation of the Fn key and related function keys in the top row on HP Pavilion and other HP laptops, the following components are required from the official site
- HP Software Framework, HP On-Screen Display, and HP Quick Launch from the " Software- solutions".
- HP Unified Extensible Firmware Interface (UEFI) Support Tools from the Utility - Tools section.
However, for a particular model, some of these items may not be available.
To download the necessary software for your HP laptop, search the Internet for "Your_laptop_model support" - usually the first result is the official page on support.hp.com for your laptop model, where in the "Software and Drivers" section, just click "Go" , and then select the version of the operating system (if yours is not in the list, choose the closest one in chronology, the bit depth must match) and download the necessary drivers.
Additionally: in the BIOS on Asus laptops, there may be an item to change the behavior of the Fn key. Located in the “System Configuration” section, the Action Keys Mode item - if Disabled, then the function keys work only with Fn pressed, if Enabled, then without pressing (but to use F1-F12, you need to press Fn).
