Suggested March 2024 F / Function Keys Not Working (Aka F1

If you’re a frequent computer user, you may have encountered a problem with your keyboard function keys not working at some point.

Function keys are a set of keys located at the top of your keyboard, usually labeled F1 through F12. They are designed to perform specific actions on your computer, such as adjusting screen brightness, controlling volume, or being used as shortcuts like the F1 key for seeking help in MS Office.

When these F keys stop working, it can be frustrating and hinder your productivity.

There are several reasons why your function keys may not be working, and in this blog post, we’ll explore some common causes and solutions. Whether you’re using a Windows PC or a Mac, we’ll cover the steps you can take to troubleshoot and fix this problem, so you can get back to using your computer efficiently.

These techniques should assist you in troubleshooting and resolving keyboard issues, whether you’re using a desktop computer or a laptop.

So, if you’re ready to get your F1-F12 keys back up again, read on!

Restarting your computer is one of the most fundamental troubleshooting techniques that can help resolve a variety of software and hardware issues, including malfunctioning Function keys.

When your F keys stop working, there could be a problem with the driver or software that controls them. Restarting your computer allows these drivers and the software responsible for Function keys to be reloaded, which may help to resolve the issue.

Furthermore, restarting your computer can assist in resetting any settings that may be causing the issue.

In some circumstances, restarting your computer may not resolve the problem with your Function keys. If this is the case, you can try some of the other methods described in this blog post.

It is tempting to begin random fixes without a clear understanding of why the F keys are not working. You first need to take the time to determine whether the problem is the keyboard hardware or software. If you make that your starting point, your work will be easier and less frustrating.

The easiest way to confirm if the problem is Hardware related is to try the Function keys on a different keyboard on the same computer to see if it works. And if it turns out working fine on this other keyboard, it means your keyboard is not in good condition. Some of the guides here may help fix a faulty keyboard.

However, if after trying a different keyboard you see no changes, it means the issue is software related, which we will address here.

If you’re using an external keyboard and your F1-F12 keys are not working, it’s possible that your keyboard is not properly connected to your computer. This can happen if the keyboard is not plugged in all the way or if the USB port on your computer is not functioning properly.

To address this issue, try the following steps:

    Check the USB connection: check if your keyboard is properly connected to your computer. Make sure that the USB cable is firmly plugged into the USB port on your computer. If your keyboard has a wireless connection, make sure that it’s properly paired with your computer.

    Test another USB port: If your keyboard is properly connected and you’re still having issues, try plugging it into another USB port on your computer. Sometimes, certain USB ports may not work properly, so testing a different port can help identify the issue.

    In some cases, you may think that these keys are not working when, in fact, they just need to be used in conjunction with the FN key.

    Many keyboard manufacturers design their keyboards with function keys that require the use of the FN key to activate certain functions. This design allows for more functionality to be packed into a smaller space on the keyboard.

    Unfortunately, this design can cause confusion for some users who may not be aware of the need to use the FN key in conjunction with the function keys. As a result, they may think that the keys are not working when, in reality, they just need to use them correctly.

    To use the function keys with the FN key, follow these steps:

      Look for the FN key on your keyboard. It’s usually located near the bottom left-hand side of the keyboard, between the CTRL and the Windows Logo key.

      Identify the function key you want to use. These keys are usually labeled F1 through F12 and are located at the top of the keyboard.

      Press and hold the FN key while pressing the desired function key. For example, if you want to adjust the screen brightness, you will hold down the FN key and press the brightness up or down key.

      Release both keys once you’ve achieved the desired result.

      Thus, if you’re experiencing issues with your keyboard’s F keys not working, it’s important to understand that some keyboards require the use of the FN key to activate certain functions. By following the steps outlined above, you can ensure that you’re using the function keys correctly and making the most of your keyboard’s full range of functionality.

      Are the function keys not still working even when you use them with the FN key?

      This issue can be caused by a key on your keyboard that locks the FN key.

      Lock keys are special keys on your keyboard that, when pressed, lock certain functions in place. For example, the Caps Lock key locks all letters in uppercase, and the Num Lock key locks the numeric keypad in place.

      Unfortunately, some keyboards have an F Lock or F Mode key that can cause confusion for users who may not be aware of its function. This key locks the FN key, making it seem like the function keys are not working when pressed together.

      How to Unlock Your Keyboard’s Function Keys:

      To unlock your keyboard’s function keys, follow these steps:

        Look for a key on your keyboard that has these labels on it: F Lock, or F Mode.

        Press this key to unlock the FN key.

        If you can’t see the F Lock or F Mode key on your keyboard, press FN + Esc simultaneously.

        By following the steps outlined above, you can unlock your keyboard’s function keys and ensure that they work properly.

        The Function keys failure may also be due to driver issues. So, you need to take some time to review or inspect the keyboard drivers and settings.

        At times, a typical occurrence is that the driver that helps manage your keyboard may be having issues due to reasons that include:

        The installation of third-party software.

        Switching off your computer without using the recommended shutdown command.

        You can start by updating or reinstalling the keyboard driver using these straightforward steps:

          On the Search Bar next to the Windows Icon on the left-hand side of your screen, type “Device Manager.”

          Tap Uninstall Device.

          Reboot the Computer.

          Windows will then automatically identify the uninstalled keyboard and will, in turn, reinstall the latest driver for that specific keyboard.

          If, after updating or reinstalling the keyboard driver, you are still not able to get the Function keys working again, the next fix to try is to install an older version of the keyboard driver.

          To do so:

            Press the Windows Key and R at the same time to open the Run box.

            Type “ chúng tôi ” and hit Enter.

            Choose “Browse my computer for drivers.“

            Select “Let me pick from a list of available drivers on my computer.”

            Wait for the process to finish, then restart your computer and check if the issue is fixed.

            Sticky Keys is a Windows feature that enables users to perform keyboard shortcuts by pressing one key at a time rather than holding down multiple keys simultaneously.

            Although this feature can be helpful for individuals who have trouble holding down multiple keys at once, it can cause issues with the Function keys and other keys on the keyboard.

            If you have enabled Sticky Keys on your Windows computer and are experiencing problems with the Function keys not functioning correctly, this could be due to Sticky Keys intercepting the key press and altering its behavior.

            The Function keys are sometimes used in combination with other keys to perform various functions. For example, the FN key can be used with the function keys to perform functions like adjusting volume and brightness. If Sticky Keys is activated, it may interfere with the Function keys’ functionality and prevent it from working correctly.

            To resolve this issue, you can disable Sticky Keys on your computer. Follow these steps to do so:

              On the Search Bar next to the Windows Icon on the left-hand side of your screen, type “Control Panel.”

              Select the Ease of Access section.

              Under the Ease of Access Center, tap on “Change How Your Keyboard Works.”

              Filter Keys is an accessibility feature in Windows that helps people who may have difficulty holding down multiple keys at once by making the keyboard more user-friendly.

              When the Filter Keys feature is enabled, Windows will ignore brief or repeated keystrokes and will not respond to keystrokes that are held down for too long. This feature can help prevent accidental keystrokes and make it easier for people with motor impairments or disabilities to type on a computer.

              So, if you are trying to use the Function keys with some other key(s) like the FN key with no success, it means that having the filter keys enabled is one possible reason your Function keys may have some issues. Follow the steps below to turn off filter keys on your windows:

                On the Search Bar next to the Windows Icon on the left-hand side of your screen, type “Control Panel.”

                Select the Ease of Access section.

                Under the Ease of Access Center, tap “Change How Your Keyboard Works.”

                Turn off Use Filter Keys by swiping the Toggle Bar.

                When was the last time you cleaned your keyboard? Most times, when Computers experience issues like the Function keys not working, the first thought is that it may be a hardware problem or something complex.

                But it is essential to note that simple things, such as the accumulation of dust or debris over time, can lead to the failure of some parts of a keyboard.

                It is typical for dirt to accumulate over time which may easily be due to some of your habits. If you often eat while using your computer, crumbs may fall and find their way into the keyboard, which may cause keyboard issues.

                Too much dust or debris may hinder the proper functioning of your keys as they may get clogged over time. Here are some of the ways you can clean your keyboard:

                    Working Of Erode() Function In Opencv

                    Introduction to OpenCV erode

                    The operations performed on the binary images based on the shape of the images are called morphological operations and there are two basic morphological operations namely erosion and dilation where the process of eroding away the boundaries of the foreground object is called erosion using which the small white noises in the image can be removed, the two connected objects can be detached, etc. and we make use of a function called erode() function by providing kernel value to perform erosion of the given image in OpenCV and the erode() function returns an image with erosion performed on it.

                    Start Your Free Software Development Course

                    Syntax to define erode() function in OpenCV is as follows:

                    erode(input_image, kernel, anchor, iterations, bordertype, bordervalue)

                    where input_image is the image that is to be eroded,

                    kernel represents the kernel matrix,

                    anchor represents integer type variable representing anchor point,

                    iterations represent the number of times erosion is applied,

                    bordertype represents the type of border to be added and

                    bordervalue represents the value of the constant border.

                    How erode() function works in OpenCV?

                    Working of erode() function in OpenCV is as follows:

                    The erode() function in OpenCV is used to perform erosion of images.

                    The erosion of images is mostly performed on binary images.

                    A kernel is a small matrix used for blurring of images, sharpening of images, detection of edges in the images, etc. in image processing.

                    The working of erode() function begins by the kernel sliding over the image.

                    If the value of the pixels under the image is 1, the pixel in the original image is also made 1.

                    If the value of the pixels under the image is not 1, the pixel in the original image is made 0, also called eroded.

                    Hence the white region in a given image decreases as the pixels near the region of boundary will be discarded.

                    The erode() function returns an image with erosion performed on the image.

                    Examples

                    Let us discuss examples of OpenCV erode.

                    Example #1

                    OpenCV program in python to demonstrate erode() function to read the given image using imread() function, perform erosion of the image using erode() function, and display the eroded image as the output on the screen:

                    #importing the required modules import cv2 import numpy as np #reading the image which is to be eroded using imread() function imageread = cv2.imread('C:/Users/admin/Desktop/images/lo.jpg') #defining the kernel matrix kernel = np.ones((5,5),np.uint8) #using erode function on the input image to be eroded erodedimage = cv2.erode(imageread,kernel,iterations = 1) #displaying the eroded image as the output on the screen cv2.imshow('Eroded_image', erodedimage) cv2.waitKey(0)

                    The output of the given program is shown in the snapshot below:

                    In the above program, we are importing the required modules. Then we are reading the image which is to be eroded using imread() function. Then we are defining the kernel matrix. Then we are making use of erode() function to perform erosion of images. Then we are displaying the eroded image as the output on the screen. The output is shown in the snapshot above.

                    Working And Examples Of Jquery Queue() Function

                    Introduction to jQuery queue

                    The jQuery queue() function is used to shows the queue of functions to be executed on the selected element. The jQuery queue() function is a built-in function in jQuery. The queue() function performs on a selector to know how many functions to execute; the queue represents one or more functions waiting to execute. The element has only one queue, the “fx” queue as the default queue in jQuery, but the element can have more than one queue. As the queue() function shows the queued function on the selected element, the dequeue() function removes the function from the queue from the elected element, so both of these functions are sometimes used together.

                    Web development, programming languages, Software testing & others

                    Syntax

                    $(selector).queue(qName);

                    qName – This is an optional parameter that specifies the name of the queue. Whereas the default queue is “fx”.

                    Working of the jQuery queue() function

                    The jQuery queue() function uses the selector to show the queue of function to be executed on it. The selector can also be an element, id, or class. This function accepts one parameter that is the name of the queue. For example, to a div element, if we apply some functions like animate(), slide(), fade(), and all, so all these functions queued into the queue of the div element, and from the queue one by one all function executed on the div element.

                    Examples for the jQuery queue() function

                    Below are the example of the jQuery queue() function to show the length of the queue –

                    Next, we write the html code to understand the jQuery queue() function more clearly with the following example, where the queue() function is used to show the length of the div queue, as below –

                    Example #1

                    Code:

                    $(document).ready(function() { var div_ele = $(“div”); div_ele.animate( {height : 200, width : 200}, “slow” ); div_ele.animate( {height : 350, width : 350}, “slow” ); div_ele.slideUp(200); div_ele.fadeIn( “fast” ); $( “h3” ).text(“The length of the queue is : ” + div_ele.queue().length ); }); }); jQuery queue() for div element.

                    Output:

                    As in the above program, the four functions are applying to the div element, which gets queued into the queue of the div element. Later in the code, the length of this queue displays four, which are the same as the number of the function applied, as we can see in the output.

                    Example of jQuery queue() function to show the length of function queue which are applied in chaining –

                    Next, we write the html code to understand the jQuery queue() function, where the queue() function is used to show the length of the queue where functions are applied to div element in chaining, as below –

                    Example #2

                    $(document).ready(function() { var div_ele = $(“div”); div_ele.css(“color”, “red”).slideUp(2000).slideDown(2000); alert( “The length of the queue is : ” + div_ele.queue().length ); }); });

                    Output:

                    As in the above program, the two functions are applying to the div element in chaining form(slideUp and slideDown), which gets queued into the queue of the div element. Later in the code, the length of this queue displays two, which are the same as the number of the function applied, as we can see in the output.

                    Example to show the use of queue() and dequeue() function together –

                    Next, we write the html code to understand the jQuery queue() function, where the queue() function and dequeue() function use together on the div element, as below –

                    Example #3

                    $(document).ready(function() { var div_ele = $(“div”); div_ele.css(“color”, “green”).slideUp(2000).slideDown(2000); div_ele.slideUp(2000); $( “h3” ).text( “The length of the queue is : ” + div_ele.queue(“fx”).length ); }); var div_ele = $(“div”); div_ele.dequeue(); $( “h3” ).text( “The length of the queue is : ” + div_ele.queue().length ); }); });

                    Output:

                    Conclusion

                    The jQuery queue function is a built-in function in jQuery, which is used to shows the queue of functions to be executed on the selected elements.

                    Examples of PHP exit

                    Lets us discuss a few examples.

                    Example #1

                    PHP program to illustrate the working of exit function where we try to connect to a website through PHP program and if unable to connect, exit the script along with an error message by making use of exit function:

                    Code:

                    <?php #a variable called website is used to store the URL of the website that is to be connected. #fopen function is used in read mode to read the contents of the website fopen($website,”r”) #in case if the program is unable to connect to the website and read the contents of the website, the current script is terminated along with an error message using exit function or exit(“Unable to connect to the website: $website “);

                    Output:

                    In the above program, a variable called website is used to store the URL of the website that is to be connected. Then fopen function is used to open the website in read mode to read the contents of the website. In case the program fails to connect to the website or fails

                    Example #2

                    PHP program to illustrate the working of exit function where we try to connect to a website through PHP program and if unable to connect, exit the script along with an error message by making use of exit function:

                    In the above program, a variable called website is used to store the URL of the website that is to be connected. Then fopen function is used to open the website in read mode to read the contents of the website. In case the program fails to connect to the website or fails to read the contents of the website, then an error message is displayed while terminating the script by making use of the exit function which is displayed as the output on the screen.

                    Example #3

                    PHP program to illustrate the working of exit function where we try to open a file by specifying the path to the location of the file through PHP program and if unable to open the file, exit the script along with an error message by making use of exit function:

                    Code:

                    <?php #a variable called filepath is used to store the path to the location of the file that is to be opened. $filepath = “C:/Users/admin/Desktop/check”; #fopen function is used in read mode to read the contents of the file present at the location specified fopen($filepath, “r”) #in case if the program is unable to open the file present at the location specified and read the contents of the file, the current script is terminated along with an error message using exit function or exit(“Unable to open the file present at the location $filepath”);

                    Output:

                    In the above program, a variable called filepath is used to store the path to the location of the file to be opened. Then fopen function is used to open the file in read mode to read the contents of the file from the path that specifies the location of the file. In case the program fails to open the file present at the location specified by the path of the file, the program terminates displaying an error message by making use of the exit function which is displayed as the output on the screen.

                    Outlook Quick Print Not Working

                    Outlook allows users to print attachments directly from the Outlook app via the Quick Print option. However, if the Outlook Quick Print is not working in Windows 11/10, here is how you can troubleshoot the issue. You need to follow these tips and tricks to enable Quick Print in Outlook and print attachments without leaving Outlook.

                    What is Quick Print in Outlook?

                    Quick Print lets you print an attachment in Outlook without leaving the interface. You do not need to open the attachment in order to print it on your computer. It uses the default printer to print the attachment. However, if the Quick Print option is not working anymore, or opening the wrong printer, or not opening any printer at all, the following suggestions would be handy for you.

                    Fix Outlook Quick Print not working

                    If Outlook Quick Print is not working for PDF, JPG, etc. on your Windows 11/10 computer, follow these suggestions:

                    Set default printer

                    Enable setting in Outlook

                    Use Printer Troubleshooter

                    Troubleshoot in Safe Mode of Outlook

                    Print manually

                    To learn more about these steps, continue reading.

                    1] Set default printer

                    By default, your computer manages all the assigned printers automatically, and this process works pretty well. However, if this system is not working for you or on your computer, you need to set the default printer manually.

                    No matter whether you have one or multiple printers attached to your computer, you can always use this option to choose one of them as your default printer. Following that, no matter which attachment you select, Outlook will use that printer to print the corresponding attachment.

                    To set the default printer in Windows 11/10, follow these steps:

                    Search for control panel in the Taskbar search box.

                    Choose the Set as default printer option.

                    Following that, check if the problem is resolved or not.

                    2] Enable setting in Outlook

                    It is a manual method, but it works when you need to print the attachment as well as the entire email body. By default, Outlook doesn’t print the attachment, no matter whether you have an image, document, or anything else. However, if you enable this setting, Outlook will print your attachment as well.

                    For that, do the following:

                    Open the email containing the attachment.

                    Choose the printer you want to use.

                    Tick the Print attached files checkbox.

                    Now, Outlook will print the attachment alongside the email body.

                    3] Use Printer Troubleshooter

                    As this problem may belong to the printer setting itself, you may need to use the Printer Troubleshooter to get it resolved. There are two troubleshooters you can use. The first one is the common Printer Troubleshooter that you can find by following these steps:

                    Press Win+I to open Windows Settings.

                    Find the Printer Troubleshooter.

                    Then, you need to follow the screen instructions to run this Troubleshooter.

                    The second Troubleshooter is device-specific. For that, you need to follow these steps:

                    Open the Windows Settings panel.

                    It will run the Troubleshooter automatically and immediately.

                    4] Troubleshoot in Safe Mode of Outlook

                    In case you don’t know, you can open Outlook in Safe mode. Like the Windows Safe mode, Outlook’s Safe mode also excludes all external add-ins and settings. To open Outlook in Safe mode, press Win+R to open the Run prompt, type outlook /safe, and hit the Enter button.

                    If you find the same problem here, you need to follow other steps. However, if you do not find the same problem here, you need to close the Safe mode and disable all Outlook add-ins.

                    5] Print manually

                    It is probably the last thing you need to do when none of the aforementioned solutions has worked for you. Although it is not a permanent solution, it works whenever you are in a hurry. For your information, you can always download the attachment and print it on your computers like any other document or image.

                    How do I enable print options in Outlook?
