Fn button not working on lenovo laptop

BIOS settings

If you just want to change the operating mode of the F-keys from functional to multimedia or vice versa, without disabling the Fn key completely, use the BIOS options. Now in almost all laptops this feature is switched there, and by default, after purchasing the device, multimedia mode is activated, thanks to which the user can control the display brightness, volume, rewind and other options.

Expanded on how to change the mode of operation of the F-keys through the BIOS, it is written in the material at the link below.

Keyboard shortcut

This option is far from universal, since depending on the brand and model of the laptop, the set of secondary assignments for the top row of keys differs. Nevertheless, it can help some of the readers, and they do not have to go to the more time-consuming method.

Examine the top row of laptop keys. If there is a lock icon that blocks / allows Fn to work, try using it. Often such an icon is located on Esc, but perhaps it could be in a different place.

In addition, sometimes instead of a lock there is an inscription “FnLk” or “FnLock”, as in the example below.

Press the Fn Esc key combination to unlock / lock the operation of the additional F-row mode.

This feature is available in certain laptop models from Lenovo, Dell, ASUS and some others. In modern HP, Acer, etc., blocking, as a rule, is absent.

Turn Fn on and off on laptop keyboard

As mentioned above, depending on the purpose for which the laptop is used, the number of F-keys is used differently for each user. Some people need exactly the functional F-keys, while others are more comfortable with their multimedia mode. When the desired does not coincide with reality, you can turn to the ways to enable and disable the Fn key and, as a result, the operation of the entire row of F-keys.

How to enable or disable the Fn key on a laptop

The Fn key, located at the very bottom of laptop keyboards, is required to call the second mode of the F1-F12 keys. In the latest models of laptops, manufacturers increasingly began to make the multimedia mode of the F-keys the main one, and their main purpose has faded into the background and requires simultaneous pressing with Fn. For some users, this option seems convenient, for others, on the contrary, not. In this article, we will explain how to enable or disable Fn.

Downloading the driver

Oddly enough, the driver is responsible for the operation of Fn and the F-series subordinate to it. In its absence, the user will need to go to the official website of the laptop manufacturer and contact the support section. Usually any drivers are downloaded from there.

Further, from the list of drivers for your version of Windows (7, 8, 10), you need to find a program (or several programs at once, if they are separated by commas in the list below) that is responsible for the hotkeys. You just need to download and install her / them like any other software:

  • HP. HP Software Framework, HP On-Screen Display, HP Quick Launch, HP Unified Extensible Firmware Interface (UEFI). Some applications may not be available for a specific laptop model;
  • ASUS. “ATKPackage”;
  • Acer. “Launch Manager”;
  • Lenovo. “Lenovo Energy Management” / “Lenovo Power Management” (or “Lenovo OnScreen Display Utility”, “Advanced Configuration and Power Management Interface (ACPI) Driver”);
  • Dell. “Dell QuickSet Application” (or “Dell Power Manager Lite Application” / “Dell Foundation Services. Application” / “Dell Function Keys”);
  • Sony. Sony Firmware Extension Parser Driver, Sony Shared Library, Sony Notebook Utilities (or Vaio Control Center). For certain models, the list of available drivers will be smaller;
  • Samsung. “Easy Display Manager”;
  • Toshiba. “Hotkey Utility”.

Now you know how you can not only enable and disable Fn, but also change the operating mode of the entire row of F-keys, partially controlled by the function key.

Changing BIOS settings

Changing the priority of the Fn button using the BIOS is described in the following

You can switch the mode of using row F from multimedia to functional and leave the working Fn button using the BIOS. You need to change the corresponding settings there.

Today, on almost any laptop, you can change modes only there. over, by default, the new computer uses the multimedia mode, which allows the user to adjust the brightness and volume, control the rewinding of songs and perform other operations.

On Lenovo models, you only need to do a few things:

  • Go to BIOS after turning on the laptop. To do this, you need to press F8, ESC or another key (depending on the model).
  • Use the arrows on the keyboard to go to the “System Configuration” section.
  • Change the “Action Keys Mode” option to “Disabled” or “Enabled”.
  • Exit BIOS and save changes.

After restarting the computer, if the Action Keys Mode is set to Disabled, the multimedia mode in the F row will be disabled, and the Fn button can be assigned to the operating system to perform another operation. Enabled will enable the Fn button on a Lenovo laptop and return the ability to work in multimedia mode.

Keyboard shortcut

You can disable and enable the Fn key on a Lenovo laptop using the keyboard. This is not for everyone, as Lenovo has a fairly diverse lineup. The fact is that the set of additional functions on the top row of buttons may differ depending on the device. However, many will find this method useful and will not have to look for other methods to solve this problem.

Take a close look at the keyboard of your laptop. If it has a padlock button for Fn lock / unlock, check it. Most often, the icon is located on Esc, although the manufacturer may place it on other F-buttons. It remains to press the Fn Esc combination, which will disable or enable additional operations of the F row.

If there is no lock on the button, look for “FnLk” or “FnLock” instead. this is the same function.

This opportunity can be used not only on Lenovo laptops, but also on Dell or ASUS. On the latest Acer or HP, this solution is not provided.

How to disable and enable the Fn key on a Lenovo laptop?

There is an Fn button on the laptop keyboard, which is used when calling the additional mode of the F1-F12 keys. At the same time, in new laptops, manufacturers are gradually replacing the main mode of keys from the F row with multimedia. Therefore, to perform basic functions using these buttons, you must additionally press Fn. For some this is fine, however, there are those who do not welcome the additional use of the key. Therefore, we will talk about how to disable Fn on a Lenovo laptop.

Installing the driver in the operating system

For the Fn key and its associated F-row to work smoothly, the operating system must have an appropriate driver installed. If it is not there, you need to find it. To do this, you need to open the manufacturer’s website and go to the support or software section, where you can download the driver for your model.

In the list offered on the site, you need to select the version of Windows installed on your computer and select the necessary software to download. In the case of Lenovo, its name will be something like this:

  • Lenovo Energy Management;
  • Lenovo Power Management;
  • Lenovo OnScreen Display Utility;
  • “Advanced Configuration and Power Management Interface (ACPI) Driver”.

If anyone is wondering why the Fn button is needed, see the following.

Other solutions

Another solution to enable or disable the Fn button on Lenovo laptop is to install the Magic Keyboard program. It is universal for all laptops and has an intuitive interface, so there shouldn’t be any difficulties with turning Fn on / off.

As for Linux distribution users, they can be advised to install the Solar application designed to change keyboard and mouse settings.

There are several ways to enable or disable the Fn key on Lenovo laptops. You can change the settings in the BIOS, install additional software, or press the appropriate key combination. The process itself is not complicated and does not require specialized knowledge.

Fn and function keys F1 ÷ F12 do not work on laptop

Good day!

Oh, these modern keyboards, with which manufacturers are now doing everything. And the problem with the performance of the keys even on a new device is not uncommon.

Actually, today’s article will be about the operation and configuration of the F1 ÷ F12 and Fn function keys on laptops. The fact is that often they either do not work at all, or they do not work as they should.

over, many manufacturers “fence” the shape of the keys, their functions, on / off, setting as they please (no standardization).

Meanwhile, the keys Fn, F1, F2, F3, etc. are very important, they allow you to quickly increase / decrease the brightness and sound, turn on / off the Wi-Fi network, touchpad and much more.

In general, abandoning them means depriving yourself of the necessary functionality, which is not good.

Reasons for Fn and F1 ÷ F12 inoperability

I remind you. that in most cases, in order for the function keys to perform an alternative function (decrease the same brightness), you must press them simultaneously with the Fn key.

For example, in order to turn on / off Wi-Fi, you need to press the FnF2 combination (this is an example! Each laptop has its own combinations, see carefully the pictures on the keys).

Pressing FnF2 at the same time. turns Wi-Fi on or off / as an example!

1) Is Fn enabled? Is there no alternative button on the keyboard?

Some types of keyboards have additional F Lock or F Mode buttons. They allow you to block (disable) function keys. Take a closer look. do you have them?

F Lock key (most commonly found on classic keyboards, not laptops)

Also note that in order to use the Fn button, on some laptops you need to press the FnEsc button combination (see the screen below. a small lock should be drawn on the key). By the way, instead of FnEsc, the combination FnNumLock can be used.

2) BIOS settings (Hotkey Mode and analogs)

If you do not know what BIOS is and how to enter it, I recommend that you read this note.

In some laptops (for example, Dell Inspiron, Lenovo ThinkPad, etc.) in the BIOS, you can set the mode of operation of the function keys (i.e. they can act in a classic role, or they can immediately perform their second function without pressing Fn: turn down the sound. enable / disable touchpad, etc.).

Most often, to enter the BIOS, you need to restart the laptop, and when you turn it on (before loading Windows), immediately press the F2 or Delete keys (the buttons may be different, depending on the device model).

These modes are called: Hotkey Mode, Action Keys Mode (and other derivatives). To change their mode of operation, you need to go to the BIOS Configuration section and change the mode from Enabled to Disabled (or vice versa).

Hotkey Mode. changed mode of operation of F1-F12 keys

3) Lack of drivers and special software from the manufacturer

When drivers are installed automatically with Windows, or various kits / packs are used (for example, Driver Pack Solution), the system often does not have special software from the laptop manufacturer. As a result, some keys may not work (including functional ones).

I will consider below an example of updating such drivers using the example of ASUS (if your laptop brand is excellent, say HP, Acer, Dell, Lenovo. all actions will be the same, only the official website address will be excellent).

  • Go to the official website: https://www.asus.com/en/support/
  • Enter your laptop model and click the search button (as help: how to find your laptop model);

Next, specify your Windows version (help: how to find out what Windows OS I have) and download the drivers for Chipset, ATKPackage. Also go to the Utilities section and click on the “Show all” link.

Then install the Asus Smart Gesture from the Pointed Device section. After restarting the laptop. the keys should work.

In general, to summarize: you just need to update the drivers by downloading them from the website of your laptop manufacturer. over, you need to do this for the specific version of Windows that you are using at the moment.

If there are no drivers for your version of Windows on the laptop manufacturer’s website, then this is a serious reason to think about switching to another version of the OS (it is quite possible that because of this, some of the functionality does not work, including the function keys).

Perhaps someone will find useful an article on how to install drivers on a laptop or PC (various options are considered).

4) The problem with the keyboard itself

If you dropped or flooded the laptop with liquid. it is quite possible that the key does not work due to a physical malfunction of the keyboard.

Pay attention to whether the key reacts at least sometimes (maybe try to press it a little harder). If there is a problem with the tracks under the key, then often a stronger pressure is triggered (for example, the tracks can oxidize after flooding, or behave this way due to wear and tear).

  • replace the keyboard on the laptop with a new one (I recommend taking it to the service for diagnostics, since it will not be superfluous to check if there are any problems with something else);
  • connect an external keyboard to the USB port and use it (is it not a temporary option?);
  • reassign one key to another;
  • use the onscreen keyboard. To call it, go to: Control Panel \ Accessibility \ Ease of Access Center

Reasons why the Fn key does not work on a laptop

For a start. about the main reasons why Fn may not function on a laptop keyboard. As a rule, the problem is encountered after installing Windows (or reinstalling), but not always. the same situation may arise after disabling programs at startup or after some BIOS settings (UEFI).

In the overwhelming majority of cases, the situation with a non-working Fn is caused by the following reasons

  • There are no specific drivers and software from the laptop manufacturer for the function keys to 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 section on troubleshooting).
  • The Fn key requires the manufacturer’s utility to be running, but this program has been removed from Windows startup.
  • The Fn key behavior has been changed in the BIOS (UEFI) of the laptop. some laptops allow Fn settings to be changed in the BIOS, they may also change when the BIOS is reset.

Most often, point 1 is the reason, but then we will consider all the options for each of the above brands of laptops and possible scenarios for fixing the problem.

The Fn key does not work on a laptop. what to do?

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, conversely, without it. pressings work these actions, and pressing. the functions of the F1-F12 keys. A common problem for laptop owners, especially after updating the system or manually installing Windows 10, 8 and Windows 7, is that the Fn key does not work.

In this manual, in detail about the common reasons why the Fn key may not work, as well as how to fix this situation in Windows for common brands of laptops. Asus, HP, Acer, Lenovo, Dell and, most interestingly, Sony Vaio (if you are some other brand, you can ask a question in the comments, I think I can help). It can also be useful: How to turn on the backlight on the laptop keyboard, Wi-Fi does not work on the laptop.

The Fn key on Sony Vaio laptops

Despite the fact that the Sony Vaio laptop is no longer available, there are a lot of questions about installing drivers on them, including to enable the Fn key, this is due to the fact that very often drivers from the official website refuse to install even on the same OS, with which the laptop came with after reinstalling it, and even more so on Windows 10 or 8.1.

For the Fn key to work on Sony, usually (some may not be available for a specific model) the following three components are required from the official website:

  • Sony Firmware Extension Parser Driver
  • Sony Shared Library
  • Sony Notebook Utilities
  • Sometimes. Vaio Event Service.

You can download them from the official page https://www.sony.ru/support/ru/series/prd-comp-vaio-nb (or you can find it by request “your_model_naptop support” in any search engine, if your model doesn’t have it turned out). On the official Russian website:

  • Select your laptop model
  • On the “Software and Downloads” tab, select your operating system. Despite the fact that Windows 10 and 8 may be present in the lists, sometimes the necessary drivers are available only if you select the OS with which the laptop was originally shipped.
  • Download the software you need.

But further problems may arise. the Sony Vaio drivers do not always want to be installed. There is a separate article on this topic: How to install drivers on a Sony Vaio Notebook.

Lenovo

Different sets of Fn key software are available for different Lenovo notebook models and generations. In my opinion, the easiest way, if the Fn key on Lenovo does not work, is to do this: enter “Your_Laptop_model support” in the search engine, go to the official support page (usually the first one in the search results), in the “Top Downloads” section, click “View all »(View all) and check what from the list below is available for download and installation on your laptop for the required version of Windows.

  • Hotkey Features Integration for Windows 10 (32-bit, 64-bit), 8.1 (64-bit), 8 (64-bit), 7 (32-bit, 64-bit). http://support.lenovo.com / ru / en / downloads / ds031814 (only for supported laptops, list at the bottom of the specified page).
  • Lenovo Energy Management (Power Management). For most modern laptops
  • Lenovo OnScreen Display Utility
  • Advanced Configuration and Power Management Interface (ACPI) Driver
  • If only the FnF5, FnF7 combinations do not work, try additionally installing the official Wi-Fi and Bluetooth drivers from the Lenovo website.

Additional information: on some Lenovo laptops, the FnEsc combination switches the mode of the Fn key, this option is also present in the BIOS. the HotKey Mode item in the Configuration section. ThinkPad notebooks may also have a BIOS “Fn and Ctrl Key Swap” option that swaps the Fn and Ctrl keys.

Function keys on Dell Inspiron, Latitude, XPS, and more laptops typically require the following sets of drivers and applications to work:

  • Dell QuickSet Application
  • Dell Power Manager Lite Application
  • Dell Foundation Services. Application
  • Dell Function Keys. for some older Dell laptops that shipped with Windows XP and Vista.

You can find the drivers that are required for your laptop as follows:

  • in the support section of the Dell website http://www.dell.com/support/home/ru/ru/ specify your laptop model (you can use automatic detection or through the “View products”).
  • Select “Drivers and Downloads”, change OS version if necessary.
  • Download the required applications and install them on your computer.

Please note that the Wi-Fi and Bluetooth keys may require the original wireless drivers available from Dell for proper operation.

Additional Information: In BIOS (UEFI) on Dell laptops, the Advanced section may contain a Function Keys Behavior item that changes how the Fn key works. enables multimedia functions or the actions of the Fn-F12 keys. Also Dell Fn key settings can be in the standard Windows Mobility Center.

The Fn key on an Asus laptop

For the operation of the Fn key on Asus laptops, a set of software and drivers ATKPackage is responsible. ATKACPI driver and hotkey-related utilities, available for download on the official Asus website. In this case, in addition to the installed components, the hcontrol.exe utility should be in startup (added to startup automatically when installing ATKPackage).

How to download Fn key and function key drivers for Asus laptop

  • Searching the Internet (Google recommend) enter “your_laptop_model support”. usually the first result is the official driver download page for your model on asus.com
  • Select the required OS. If the version of Windows you need is not listed, select the closest one that is available, it is very important that the bitness (32 or 64 bit) matches the version of Windows that you have installed, see How to find out the bitness of Windows (article about Windows 10, but will work for previous OS versions as well).
  • Optional, but may increase the likelihood of step 4 being successful. download and install drivers from the Chipset section.
  • In the ATK section download ATKPackage and install it.

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 on typical problems when fixing broken function keys.

HP Laptops

For the full operation of the Fn key and its associated function keys in the top row on HP Pavilion and other HP notebooks, the following components are required from the official website

  • HP Software Framework, HP On-Screen Display, and HP Quick Launch from Software Solutions.
  • HP Unified Extensible Firmware Interface (UEFI) Support Tools from Utility. Tools.

At the same time, for a specific model, some of the above items may be missing.

To download the necessary software for an 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, select the closest one in chronology, the bit depth must be the same) and download the necessary drivers.

Additionally: in the BIOS on HP notebooks, 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 are triggered only when Fn is pressed, if Enabled, then without pressing (but to use F1-F12, you need to press Fn).

If the Fn key does not work on an Acer laptop, then usually it is enough to select your laptop model on the official support site https://www.acer.com/ac/ru/RU/content/support (in the “Select a device” section, you can specify the model manually. without a serial number) and indicate the operating system (if your version is not in the list, download drivers from the nearest one in the same bit as installed on the laptop).

In the download list, in the “Application” section, download the Launch Manager program and install it on your laptop (in some cases, you will also need a chipset driver from the same page).

If the program has already been installed, but the Fn key still does not work, make sure Launch Manager is not disabled in Windows startup, and also try to install Acer Power Manager from the official website.

Possible problems and solutions when installing software and drivers for the Fn key

  • The driver is not installed, because it says that the OS version is not supported (for example, if it is only for Windows 7, but Fn keys are needed in Windows 10). try unpacking the exe-installer using the Universal Extractor program, and inside the unpacked folder find it yourself drivers to install them manually, or a separate installer that does not check the system version.
  • Despite the installation of all the components, the Fn key still does not work. check if there are any options in the BIOS related to the operation of the Fn key, HotKey. Try to install the official chipset and power management drivers from the manufacturer’s website.

Hope the instruction helps. If not, and additional information is required, you can ask a question in the comments, only please indicate the exact model of the laptop and the version of the installed operating system.

laptop Aser Extensa 2520G Windows 10 64bit combination problem: some do not work, namely the brightness control. no, but maybe you know, when you close the lid, press the keys to go to sleep, the laptop seems to be completely cut down, and turn it on. press the power button, on Windows 7 it seemed different. that is, I do not see the difference that I turn off the laptop that is asleep, they turn on for about the same long time. MB you know what you can do with the battery, it always worked a little from 1 charge. somehow I noticed it a long time ago, in 47 minutes I discharged it playing the game, listening to music in VK, and at maximum brightness (then 7 Windows were)

Healthy, healthy. I read your posts about getting back the ability to edit the brightness level. TeamViewer was guilty, it was necessary to return the pre-installed firewood to the monitor via devmgmt.msc.

The bottom line is: Does not rob FnF11 and, of course, FnF12. The 1st one lowers the brightness level, the 2nd one increases it. On the 10th Win everything was robbed, even there (xs as 8 and 8.1) in the OS windows “on the go” displays that you are changing it, but now I switched to 7 and it does not rob. Fn is responsible for the sound output level, on / off. touchpad, other. all the rules, the brightness is not normal.

Delivered Lenovo Utility from the office. and I will look at what it will give. What do you say to this?

I will say: sit and figure out what set of Lenovo software / drivers you need to start in order to work. As a result, it will work.

All in the ass. no software from the list on the official does anything. It somehow got up, but there is no way to check it. Fn of course also put on it.

I’m already tired of sorting out. After remembering how much I have already stretched myself with these fucking OS’kami. forget it. I’d rather put it on than to take on the “big” business again. You can only superficially. put the software and see whether yes or no, without going to devmgmt.msc, firewood ID, etc what will the brain take out

I have met paranormalities, collected. alright, even within the limits of reason it is possible. But when the problem is solved by the fact that you are rebooting, and from somewhere from somewhere, “Lenovo ACPI-Compliant Virtual Power Controller” is put, you ask the question: “Why was it impossible before ?!”. But after that a trace appears: “Where did it come from? I didn’t put anything, and there were no unknown devices! Gods also appear in a similar way. from the void and hop. another splinter ?! “

ID of this splinter, by the way, just in case: ACPI \ VPC2004

Hello, I tried to check the Fn button (brightness, sound) and as it turned out, it does not work. I have an MSI laptop (7 years old), it’s old, but everything worked before.

Something on their website for your model does not have such a driver. And without holding Fn, these keys also do not work.?

Many thanks, very useful, “good” article. I faced this problem when I purchased a used one. Lenovo laptop carbon r3), it still had Windows 10k with a dead key, I had to work hard in order to unleash the potential, and when I was already discouraged, I went through the floor of the linux family, read it, got into the BIOS, opened it, and voila, I thought that. the problem is in the drivers
Huge thanks to the author, the time was well spent!
By the way, I recommend deepin excellent system.

Hello everyone! help me please! the developers have not released a driver for the FN button. now I cannot fully use all the functions. after installing wines 10 64 bits my acer e1 571 g ceased to function. I tried to find it in the BIOS, but there is nothing there. I tried to install the launcher program, nothing helped. help me please!

Did you install the RF Button driver? Try too.

Good day, laptop Acer Aspire E1-571G, Win7 64, did everything according to the instructions, Fn still does not rob, the keyboard works, all keys are normal, combinations of other keys also work.

Install Acer Launch Manager, Intel ME and RF Button drivers from the official website for your model, reboot, check.
At the same time, look in the BIOS. is there something about Fn.

I put the first and the second, rebooted. to no avail. RF could not be found under win7, in BIOS. about fn, alas, there is nothing.

Installing the required drivers

According to the number of the most common causes, there are several ways to eliminate the breakdown. The first (and most likely effective) is to install the required drivers.

The HP support site will help you find the driver you need. There, enter the product and model name of the laptop (for example, HP ENVY. 15-k110tx) and, in the “Software and Drivers” tab, download the necessary ones. Depending on the features of a particular model, you will need:

  • HP Software Framework;
  • HP On-Screen Display;
  • HP Quick Launch Software;
  • HP Unified Extensible Firmware Interface (UEFI) Support Tools.

The first three are usually found under the “Software. Solutions” tab, the last one. “Utility. Tools”.

Service start

The disabled service must be enabled and checked for its presence in the startup list. The first can be done through the “Task Manager”. Press Ctrl Shift Esc, select the “Services” tab, find HP Hotkey Monitor in it and right-click to enable.

Then press Win R. In the “Run” window, enter mscongif, after which the “System Configuration” window will open with the “Startup” tab. In it, you should select the mentioned HP Hotkey Monitor, and put a tick in front of it.

Why is the fn button not working on an HP laptop?

Consider the case when the “Fn” button does not work on a laptop. If your laptop just doesn’t work, take a look at this article: Why HP laptop won’t turn on.

For the convenience of using laptops, they provide quick access to some functions:

  • Enable / Disable Wireless Adapter.
  • Touchpad control.
  • Adjusting the screen brightness.
  • Decrease and increase volume.

The range of functions available will vary from model to model. For the sake of compactness, special functions are combined, as a rule, with a number of F1-F12 keys, and they must be used while holding down the fn key.

However, sometimes the dedicated button stops working. There are three main reasons for this:

  • Special drivers are missing or damaged. Often this situation develops as a result of reinstalling the operating system or its version mismatch with the drivers.
  • The required process or service is shut down.
  • In the case of HP Envy series notebooks, the function key behavior can be changed in the BIOS settings.

It is also theoretically possible that one button does not work as a result of damage to the keyboard pins, but this is very unlikely. As a rule, in such a situation, the key block immediately fails.

BIOS setup

To get to the BIOS menu, you must have time to press F10 before starting the operating system. Then go to the System Configuration tab. The Disabled parameter means that fn must be held down to use special functions. Enabled means that fn is necessary for the standard use of the F keys. Having set the necessary parameter, there will only be F10 again to exit the BIOS with saving the changes and continue loading the OS.

Everything breaks down sometime. But what is the disappointment of the owner if, after an awkward movement, due to the fault of children or pets, a button in the laptop flew out?

When the button on the laptop fell off, you need to correctly identify the type of its attachment and understand the assembly technology.

Before replacing the key, make sure that:

  • There is no mechanical damage in the design of the button,
  • All parts work as expected, the structure is free to move (disassembled);
  • Nothing was lost, an important detail did not fall off, everything is in place;
  • When the contacts are closed, the button works as needed (the test of pressing depends on the type of key fastening, but it is best to attach the detached button without installation and press).

A typical design of a laptop key is as follows:

  • Cover (outer rectangular surface with letter / number / symbol, etc.),
  • Sleds (someone calls them “swing”, “folding bed” or even “lift”. This is an X-shaped movable structure),
  • Membrane (combines the functions of a switch / key and a spring).

Turn Fn on and off on laptop keyboard

As mentioned above, depending on the purpose for which the laptop is used, the number of F-keys is used differently for each user. Some people need exactly the functional F-keys, while others are more comfortable with their multimedia mode. When the desired does not coincide with reality, you can turn to the ways to enable and disable the Fn key and, as a result, the operation of the entire row of F-keys.

The Fn button on the laptop does not work. What to do?

If you take a look at a laptop keyboard, at first glance, you will hardly find any differences from the keyboard that is used on a regular computer. But in fact, there is a difference and it lies primarily in the presence of the Fn key. If you click on it, nothing happens. Why is it needed in this case, you ask? It is designed to perform numerous operations in conjunction with other keys. You can find a complete FAQ on this issue in the instructions that were given with your laptop, but even so it is not difficult to determine which buttons Fn interacts with. as a rule, the symbols on them have a different color from the general one (for example, not white, but blue) Fn is like a hotkey with which you can, for example, increase the volume or darken the screen. Without it on laptops today nowhere.

It is noteworthy that this key is found on all modern laptops, be it Acer, Samsung, ASUS, Sony, Toshiba, HP, LG and so on. However, it may stop working regardless of your device model. What if this happened to you? We need to try to solve this problem. I will tell you how you can do it.

Physical breakdown

If none of the sections of this manual helped you with fixing the problem, the cause of the problem may be a breakdown of the keyboard or specifically the “Fn” key. In this case, you can resort to cleaning and checking the connection pins.

Fatal injuries are also possible, for example due to physical impact. The problem can be solved only by completely replacing the keyboard with a new one, depending on the laptop model.

Using the FN ESC combination

In many laptops, the user can “lock” or “unlock” Fn while using the system, just like Caps Lock. This allows you to quickly switch the action of the function keys.

To do this, just press the FN ESC combination. The FN key will automatically lock in the “always on” position. Therefore, now, to activate alternative functions, you will not need to press any combinations with FN, the very use of F1-F12 will cause the multimedia operation assigned to them.

Pressing this combination again will “unlock” FN. Thus, F1. F12 will again perform their previous role. Now, for example, to increase the volume, you need to hold FN.

Reasons for Fn and F1 ÷ F12 inoperability

Let me remind you that in most cases, in order for the function keys to perform an alternative function (decrease the same brightness), you must press them simultaneously with the Fn key.

For example, in order to turn on / off Wi-Fi, you need to press the FnF2 combination (this is an example! Each laptop has its own combinations, see carefully the pictures on the keys).

Simultaneous press FnF2. turns on or off Wi-Fi / as an example!

1) Is Fn enabled? Is there no alternative button on the keyboard?

Some types of keyboards have additional F Lock or F Mode buttons. They allow you to block (disable) function keys. Take a closer look. do you have them?

F Lock key (most commonly found on classic keyboards, not laptops)

Also note that in order to use the Fn button, on some laptops you need to press the FnEsc button combination (see the screen below. a small lock should be drawn on the key). By the way, instead of FnEsc, the combination FnNumLock can be used.

2) BIOS settings (Hotkey Mode and analogs)

In some laptops (for example, Dell Inspiron, Lenovo ThinkPad, etc.) in the BIOS, you can set the mode of operation of the function keys (i.e. they can act in a classic role, or they can immediately perform their second function without pressing Fn: turn down the sound. enable / disable touchpad, etc.).

These modes are called: Hotkey Mode, Action Keys Mode (and other derivatives). To change their mode of operation, you need to go to the BIOS Configuration section and change the mode from Enabled to Disabled (or vice versa).

Hotkey Mode. changed mode of operation of F1-F12 keys

3) Lack of drivers and special software from the manufacturer

When drivers are installed automatically with Windows, or various kits / packs are used (for example, Driver Pack Solution), the system often does not have special software from the laptop manufacturer. As a result, some keys may not work (including functional ones).

I will consider below an example of updating such drivers using the example of ASUS (if your laptop brand is excellent, say HP, Acer, Dell, Lenovo. all actions will be the same, only the official website address will be excellent).

In general, to summarize: you just need to update the drivers by downloading them from the website of your laptop manufacturer. over, you need to do this for the specific version of Windows that you are using at the moment.

If you dropped or flooded the laptop with liquid, it is quite possible that the key does not work due to a physical malfunction of the keyboard.

Pay attention to whether the key reacts at least sometimes (maybe try to press it a little harder). If there is a problem with the tracks under the key, then often a stronger pressure is triggered (for example, the tracks can oxidize after flooding, or behave this way due to wear and tear)

Keyboard shortcut

This option is far from universal, since depending on the brand and model of the laptop, the set of secondary assignments for the top row of keys differs. Nevertheless, it can help some of the readers, and they do not have to go to the more time-consuming method.

Examine the top row of laptop keys. If there is a lock icon that blocks / allows Fn to work, try using it. Often such an icon is located on Esc, but perhaps it could be in a different place.

In addition, sometimes instead of a lock there is an inscription “FnLk” or “FnLock”, as in the example below.

Press the Fn Esc key combination to unlock / lock the operation of the additional F-row mode.

This feature is available in certain laptop models from Lenovo, Dell, ASUS and some others. In modern HP, Acer, etc., blocking, as a rule, is absent.

Fn key does not work on ASUS laptop

The most common cause of Fn key problems is a recent reinstallation of the operating system. However, in addition to this, there may be malfunctions of drivers or physical breakdown of buttons and the keyboard as a whole.

Reasons for the inoperability of the “Fn” key on an ASUS laptop

“Fn” on the keyboard of any laptop, including devices from ASUS, plays an important role, allowing you to control additional features using function keys. In case of failure of this key, we have prepared this instruction.

Disable keys

In most cases, ASUS notebooks enable and disable the function keys by using the following combinations:

Try using the indicated keyboard shortcuts while checking the functionality of “Fn”.

BIOS settings

In the case of ASUS notebooks, you cannot disable or enable the function keys through the BIOS, but you can customize their work. If “Fn” does not work correctly on your laptop, our instructions may well help.

    Fixing a Not Working Fn Key on a Laptop

    Each laptop has
    the Fn button, which is responsible for the possibility of expanding the functionality when combined with other keys. Unfortunately, owners often face problems with the functioning of Fn. The reason may be updates, or critical changes to the system.

    In this article, we will look at the details and how to fix this problem.
    They are suitable for all well-known laptop manufacturers. Asus, Dell, HP, Lenovo, Acer and others.

    Sony Vaio laptops and Fn button

    The problem often lies in the fact that the drivers are not preinstalled from the original supplier. Install the software from the official resource https://www.sony.com/electronics/support/laptop-pc-svf-series. Select your laptop model and system bit, and then download and install the drivers. After restarting your device, the problem should go away.

    Drivers may fail to install and display a system error. Try using the archiver to unpack the startup file, it contains the driver installation files without a shell. Install through them.

    What are the Fn key combinations

    In addition to the fact that with the help of Function it is possible to activate additional features of the system, perhaps the following combinations will work for you:

    • Up Arrow Fn. Increase Volume.
    • Down Arrow Fn. Decrease Volume.
    • Right Arrow Fn. Increase Screen Brightness.
    • Left Arrow Fn. Decrease Screen Brightness.
    • Home Fn. enable music playback.
    • Pg Up Fn. turn off playback.
    • Pg Dn Fn. rewind music.
    • End Fn. fast forward music.

    There may be other combinations as well. Check it yourself on your laptop.

    How to enable or disable the Fn key

    On most laptops, the Fn button is already on and you don’t need to do anything else. Since the key is on by default, you can disable it, but this is not always possible.

    Some laptop models allow you to disable the Fn key using a combination. In other words, you hold down Fn and the button that is responsible for turning off Function.

    Second way. Disable Fn key via BIOS. Here’s what you need to do for this:

    • We reboot the laptop and quickly press the key responsible for entering the BIOS (F2, F10, F8, Del, etc.).
    • Go to the System Configuration section. (switch with arrows).
    • Find the Action Keys Mode option.
    • To turn it off, put it in the Disabled position, and to turn it on, put it in the Enabled position.
    • We exit the BIOS by pressing the F10 key, while saving the changes.

    Key assignment. what it does and why is it needed

    We found out that the Fn key allows you to enable additional laptop options. The full name of this button is Function. a combination key that works exclusively with other buttons. Most often, additional functions are built into the set of F1-F12 keys located at the top of the keyboard.

    The F1-F12 keys (not all) and other buttons will have an emblem drawn to indicate the option. To activate it, simultaneously hold down the Fn key with the function.

    • Adjusting the screen brightness.
    • Projecting to a second screen (you need to connect a second monitor).
    • Decrease and increase sound.
    • Turn on, pause and move between tracks in the player.
    • Turn on flight mode and turn off Wi-Fi.
    • Activation and deactivation
    • Activating or deactivating the touchpad.
    • Turn on sleep or hibernation mode.

    And much more. Each laptop model has different capabilities built into the keyboard controller.

    I’d like to point out that I don’t use the Fn key at all. I have Windows 10 on my HP laptop and I just need to press the keys from F1 to F12 to activate the option. That is, in my case, the built-in functions are the main ones on the keys, and not the F1-F12 themselves.

    Why is this happening? This is because the Fn key works the other way around. To fix this small problem, you need to press the Fn Lock button, if there is one.

    In addition, go to the BIOS and find the Hotkey Mode option on the Configuration tab and enable it, or vice versa turn it off.

    Do you need drivers for the Fn key? No, they are not needed. After reinstalling the system, the keyboard drivers are automatically installed. You can only update them. And the key will work anyway.

    What is the Fn key and how to enable it on a laptop

    Laptops have an Fn key, which is responsible for activating additional keyboard functions. How to enable it or why the Fn key does not work read further.

    What is the Fn key on the laptop responsible for and where is it located

    The Fn key is a button on your laptop keyboard that you can hold down to activate additional functions for other keys.

    In other words, the keyboard has keys that perform not one, but two functions. To activate the second, the Fn button must be activated.

    It should be noted that this key is available exclusively on the keyboards of laptops, netbooks and their other varieties. The fact is that the keyboard of a desktop computer is quite wide and in some cases has more features. panels with keys that are responsible for additional functionality. Most often there is a key, pressing which turned on music playback.

    Laptops are very compact devices, which also affected the size of the keyboard. To accommodate additional options, such as turning on music, changing the volume, etc., the developers have implemented the Fn key, and these functions have been embedded as a second function in the existing buttons. (Read: How the keyboard works)

    Where is the Fn key on a laptop keyboard

    In 90% of cases, the Fn function key is located on the left side of the keyboard. Next to it, such keys as Ctrl and Windows have taken root. Sometimes embedded before the Ctrl key. This arrangement is typical for notebooks HP, Asus, Acer, Lenovo, LG, Samsung and others.

    It is worth noting that the Fn key was embedded in such a place for a reason. Developers know what they are doing when it comes to usability and accessibility. In this case, it is very easy to get to the button for both a sighted person and with “touch typing”.

    If the Fn key does not work on a laptop. what to do

    There are several reasons why the Fn function key on your keyboard suddenly stopped working. Now we will consider them.

    • Failure. It is not uncommon for a key on the keyboard to break and not work. Most often this happens when the loop is hit or damaged. In the second case, you will definitely not be limited to one key.
    • Drivers. Quite a rare reason, but this is only in my opinion. It has never happened that the keyboard did not work due to improper installation of drivers. But, in any case, it is worth trying to fix the problem. To do this, in the device manager, open the “Keyboards” section and remove all drivers. Then restart your laptop. If the drivers have not been installed again, use the Driver Pack Solution to install.
    • It is disabled. Are you doing something wrong? It is possible that the key is simply disabled by a combination or in the BIOS. Try to recheck everything.
