The PC keyboard is an extremely thoughtful device in terms of optimizing use. Here, with a limited number of keys, it was possible to obtain a huge number of combinations for which one or another action can be programmed. It's definitely convenient. Laptop manufacturers went even further and added an Fn keyboard in addition to traditional keys. And the presence of this button may introduce some uncertainty when working with the device, especially for people who are just starting to master compact PCs. By accidentally or habitually touching a key, many users experience inconvenience, and they naturally have a question about disabling the Fn button on a laptop. This will be discussed further.

Fn key on keyboard

The Fn key is an auxiliary element of the device function control system. Its implementation made it possible to significantly expand the capabilities of the keyboard. Moreover, it is interesting that the key itself does not produce a direct effect. More precisely, this action is not involved in traditional input operations, which is why many users want to disable the Fn key. In this it has some similarities with the “Ctrl” or “Shift” keys.

The peculiarity of its functioning is that when pressed, a full-size keyboard is emulated at the system level, which allows you to assign additional actions to existing physical keys. The technology is successfully used in the manufacture mobile devices, as well as compact keyboards, which are becoming increasingly popular today.

For ease of understanding and the ability to visually separate the buttons that are associated with the Fn key, they are usually designed in a single color that differs from the general color scheme information input panels. Typically these keys are the top row from “F1” to “F12”. Thus, thanks to the installation of just one additional physical key, it was possible to obtain the full functionality of twelve. Fn is usually located closer to the lower left corner of the keyboard or on both sides for duplication, which makes it easier to use regardless of the dominant hand.

If we talk about actions that can be performed using this key, then we are usually talking about system actions and control peripheral devices. For example, the Fn+F1 key combination puts the laptop into sleep mode, and Fn+F6 disables the touchpad, etc.

How to disable the Fn key

However, no matter how useful the Function key is by design, if it causes inconvenience during actual use, then it must be disabled. It should be understood here that each manufacturer can make certain changes program code in order to individualize products, and therefore the action can be carried out in several ways.

In some cases, disabling the Fn modifier key can be done through BIOS system. There are several ways to enter this operating mode of the device, depending on the specific manufacturer. Usually the corresponding key is indicated on the screen when the laptop is turned on. In some cases it may be F2, Del or some other button.

Reliable information regarding specific model can be obtained on the official website of the manufacturer. The BIOS entry key must be pressed at the time between pressing the power button and the appearance of the first screensavers. It may not work out the first time, but sooner or later everything will be as it should be.

For people performing the operation for the first time, it should be explained that when entering the menu, the mouse will stop working, and all necessary actions must be performed using specialized keys (up, down, right, left, etc.).

1. So, when entering the BIOS, you will need to go to the “SYSTEM CONFIGURATION” tab, where using the arrows and the Enter key you need to open the “Action Keys Mode” menu.
2. In the opened context menu you need to select “Disabled”, confirm and save the changes. Then reboot the device. If everything was done correctly, the Fn key will be disabled. It turns on the same way.
3. If you can’t disable the button through the BIOS, you can try using a certain key combination, which will differ depending on the manufacturer.
4. In some cases, the Fn + Num Lock combination may work, sometimes pressing Fn + F11 at the same time will have the effect.

In some cases, disabling a key will require using specialized software. It goes without saying that programs were not developed individually for this key, but controlling it may be among other tasks performed. An example of such a program is Toshiba HDD Protection (http://www.toshiba.eu/generic/hddprotection/), for devices from this company. If you go to the “Optimization” section and open the “Accessibility” tab, you can disable the key by simply unchecking the corresponding item.

Sony laptops have Vaio Control Center", and for Samsung devices there is "Easy Display Manager". The programs are free and are located on the official websites of the manufacturers.

There are many ways to disable the Fn key, and everyone can choose which one to use. However, wouldn’t it be more logical to put in a little effort and start using its functionality?

In recent years, desktop computers have faded into the background and given way to their more compact counterparts - laptops. They are light, practical, mobile. They are convenient to take with you on a trip, to the country, on a visit, or just to sit in a cozy cafe, surfing the Internet over a cup of hot cappuccino.

You've probably noticed on your laptop Fn key. It is located in the lower left corner, to the left or right of Ctrl. What is this mysterious button for (which you have probably never used in your life)?

The name of the Fn key itself comes from the first vowels of the word F u n ction. On your laptop keyboard, you may see keys that have symbols and lettering in a different color. Mostly it is red or blue. And such keys are called keys quick access. With their help, you can control the media player on your laptop, work with screen brightness and battery saving modes, enable or disable wireless network access, and adjust the volume. You can also put your laptop into sleep mode. All these functions will only work in combination with the Fn key.

How does the Fn key work? (example on a Lenovo laptop)

It is difficult to answer the question where and what combination for each individual device. Each brand of laptop has different shortcut keys. But the principle of their operation is absolutely the same for all major brands HP, Asus, Acer, Lenovo, Samsung, LG. And they differ slightly. I will describe the functionality of the Fn button for a Lenovo laptop.

So, holding down the Fn button in combination with hot keys, we get:

• Fn+F1 - puts the computer into sleep mode.
• Fn+F2 - turn on/off the monitor.
• Fn+F3 - switches the display to the connected monitor or projector module.
• Fn+F4 - monitor extension.
• Fn+F5 - enable wireless modules communication: wireless network adapters, Bluetooth.
• Fn+F6 - enable/disable touchpad- laptop mouse.
• Fn+F9, Fn+F10, Fn+F11, Fn+F12 - work with the media player - resume/pause, stop, track back, track forward, respectively.
• Fn+Home - pause in media files.
• Fn+Insert - enable/disable Scroll Lock.
• Fn+up arrow/down arrow - increase/decrease monitor brightness.
• Fn+left arrow/right arrow - decrease/increase volume for media players.

As you can see, the functionality of our key is very great; knowledge of these combinations will allow you to use your computer keyboard very effectively without resorting to a mouse.

How to enable or disable the Fn key?

In order to enable or disable the Fn key on a laptop, you can use several methods. The first method is to use the Fn+NumLock key combination. Pressing these keys simultaneously will disable the Fn button, pressing again will activate the key. This method may not work on all laptops.

In some cases, the Fn key is enabled or disabled through Bios. To do this, you need to enter Setup Utility, then go to System Configuration and in the Action Keys Mode tab turn off Disabled or enable Enabled given Fn function.

If the Fn key does not work on a laptop

If the above two methods do not work or the Fn key does not work at all. Then you need to use programs for the Fn key. You can find a great variety of such programs on the Internet. To make it easier to decide which programs are suitable for your brand of laptop, we suggest you familiarize yourself with a short list of such programs.

For Samsung laptops - Easy Display Manager (the disk with the program is included with the laptop). This program is freely available on the Internet.

For Sony laptops, you should use the following programs - Sony Shared Library, Setting Utility Series, Vaio Event Service, Vaio Control Center.

For Toshiba laptops - Hotkey Utility, Value Added Package, Flash Cards Support Utility.

Also, many laptops use the universal Magic Keyboard program.

Drivers for the Fn key

If your button still does not work, then you should check the drivers for your keyboard, or more precisely for the Fn key. Such “firewood” should come with the laptop (be sure to check it when purchasing), or you can download it from the Internet. Download from the Internet from the official pages of laptop manufacturers. So on the official websites there are Fn button drivers for Sony, Lenovo, Samsung, HP, DNS, Dell, Toshiba, Acer, Asus, LG.

By holding down the Fn button, and then any multimedia key with an additional symbol, you can adjust the sound volume, screen backlight, and turn on battery saving mode. However, occasionally this key interferes, only if in the process Windows reinstallation something is vulgarly wrong, or you simply want to have access to the required function without additional clicks.

Occasionally you need to disable additional keyboard probabilities, say, entering digital values. On laptops, these buttons can be located either as a separate block or on ordinary keys using the possibility of switching through hot keys.

You will need

• Laptop (netbook) of any model.

Instructions

1. Currently, laptops use two options for entering numbers from the keyboard: using the number strip, which is located above the letters, and also using an additional block of keys. If the 1st option is used by virtually everyone, then the 2nd option is available only to those who have a key block (often called a NumLock keyboard). It is used for quickly entering a large number of numbers - a godsend for accountants and other people whose professions involve entering numbers.

2. The second type of keyboard can be disabled using the NumLock indicator key. Press it and check the action of this key: the numbers should mechanically change to the navigation system. You can monitor the operating status of this keyboard using the indicator: if it is lit, it means that the digital mode is on; on the contrary, the navigation mode is on. It is also worth noting that while the indicator is on, you can use navigation - to do this, hold down the Shift key.

3. However, do not forget that the action of this key may be different. This happens when special utilities are built into operating system tools. As an example, we can cite the possibility of using this indicator as a marker of the current layout. When you select one layout, this indicator lights up, but another layout gives the exact opposite result.

4. We must not forget that a huge number of mobile devices produced today do not have additional keyboard. Alternative input of numbers can be done using hot keys. Press the Fn key combination and the desired key with a number symbol on it. Here, disabling is done by pressing the NumLock key, if available, and simply pressing the Fn function key.

Occasionally, when working with a laptop, users notice that the function keys F1-F12 have an unusual purpose. When you press them, the screen brightness and sound level change, WI-FI turns on and off, or even the laptop goes into sleep mode. And in order to return these keys to their normal functionality, you have to press Fn every time. This disturbs the user and slows down the work.

And in some cases, to solve this problem you need to install a special utility or deactivate the Fn key in the BIOS.

2. If you bought a laptop from the HP manufacturer, then to disable the Fn function you will have to deactivate it in the BIOS. To do this, when turning on the laptop, hold down the F2 or Del key (depending on the model). Occasionally, the F10 or Esc keys are used for this purpose. If you cannot enter the BIOS, look for information about motherboard in the User Guide.

3. To navigate through the BIOS, use the Left/Right/Up/Down arrow keys. Go to the System Configuration tab and select the Action Keys Mode option. The feature is enabled by default - the switch is in the Enabled location. Change the parameter value to Disabled and press the F10 key to save the changes and exit the BIOS.

Users of netbooks and laptops know that many of their models are equipped with an additional key - Fn. With its help, you can increase the volume, switch music, etc.

Function key

Laptops (netbooks) from HP, Asus, Smasung, Compaq and others are equipped with special function keys, with the support of which the user can quickly switch between music, launch wireless networks, increase or decrease the volume and perform other manipulations with the device.

Disabling the Fn key

Of course, you can change the settings of these keys or completely disable the Fn button on your netbook. First, it must be said that this method far from being the easiest, but if everything is done positively, you can avoid a lot different tasks. On HP laptops (netbooks), you can easily disable the function key from the BIOS. In order to enter the BIOS, you need to turn on (restart) the computer and press the ESC or F10 key (depending on the model of your device). After the BIOS window opens, you need to go to the System Configuration tab. There are a lot of different parameters here, but to disable or metamorphose the function keys you will need the Action Keys parameter. It needs to be changed to Disabled and save metamorphosis with support for the F10 button. After this, the Fn key will be disabled. On devices from Asus, Samsung and Fujitsu, it is easier to disable the function key. Let's say, on laptops (netbooks), from Asus, the Fn key is disabled using a combination of the Fn and NumLk keys. On other models, other key combinations may work, say: Fn and Insert, Fn and F11, Fn and F12, or even NumLk. It is worth noting that the biggest problem with disabling the function key will be caused by laptops (netbooks) from Toshiba, because for this you will have to download and install a special software- HDD Protector. After installing and launching this program, you need to go to the “Optimization” tab, where you need to find the “Special probabilities” item. When a new window opens, you should uncheck the “Use Fn key” box. These metamorphoses must be confirmed with the support of the “Ok” button. This will disable the function key.

Tip 11: What is the Fn button for on a laptop or netbook?

The keyboards of many laptops or netbooks have an Fn button. Why is it needed?

The keyboards of most laptops, ultrabooks and netbooks have an Fn button, but unfortunately the instructions for the gadget do not always contain a description of its use and inexperienced users, by randomly pressing it, can accidentally turn off Bluetooth or wireless network, the touchpad will switch to the numeric keypad from the rod one, and the user will think that the laptop is broken.

In fact, the Fn button is quick access to some possibilities and computer settings. You need to remember that to quickly call up settings or turn a function on/off, you need to lightly hold down Fn and at the same time the second key with the symbol of the function.

Take a closer look at the keyboard. In addition to letters and guide buttons labeled Enter, Shift. Ctrl, Alt, etc., on the keyboard you will find buttons with small icons drawn in the same color as the letters “Fn” (as usual, this is a more faded color than the others used in the keyboard design). By pressing Fn simultaneously with the button on which the loudspeaker is depicted, you can control the sound on and off, by pressing Fn simultaneously with the button on which the icon indicating WiFi network it is allowed to turn the receiver-transmitter on and off WiFi laptop etc. Turning on/off the touchpad, sleep mode, adjusting screen brightness, as well as switching to working with the numeric keypad (if the laptop keyboard is not full-size) also works correctly.

It is worth understanding the functions that can be quickly controlled using the Fn button, from changing the same settings in operating system often much more difficult and longer.

If the Fn key on a laptop does not work, then it is possible that it is disabled in the BIOS. If this is not the case, you will have to install special software that comes with your specific PC model.

Example of using the Fn button: The photo shows that pressing Fn and F3 at the same time turns Bluetooth on and off.
