This option is far from universal, since depending on the brand and model of the laptop, the set of secondary keys assigned to the top row of keys differs. Nevertheless, it may help some of the readers, and they will NOT have to go to the more laborious 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 F-row additional mode.
This possibility is available in certain models of Lenovo, Dell, ASUS and some others laptops. In modern HP, Acer, etc. Blocking, as a rule, is absent.
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 the second, on the contrary, it is lacking. In this article, we will explain how to enable or disable Fn.
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 need just the functional F-keys, while the second is 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.
If you just want to change the operating mode of the F-keys from functional to multimedia or vice versa, and do not disable 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 in how to change the operating mode of the F-keys through the BIOS, it is written in the material at the link below.
Oddly enough, the driver is responsible for the work 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 listed below, separated by commas) that is responsible for the hotkeys. It only remains to download and install it 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.
Installing the driver in the operating system
For the Fn key and its associated F-row to function smoothly, the Operating System must have the Corresponding 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:
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 BIOS. You need to change there Relevant settings.
Today, on almost any laptop, you can only change modes 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, just a few steps are enough:
- 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 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 allow you to enable the Fn button on a Lenovo laptop and return the ability to work in multimedia mode.
How to disable and enable the Fn key on a Lenovo laptop?
The laptop keyboard has an Fn button, which is used when invoking 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 a multimedia one. Therefore, to perform basic functions using THESE buttons, you must additionally press Fn. For some this is fine, but there are those who DO NOT welcome additional key usage. Therefore, we will talk about how to disable Fn on Lenovo laptop.
- Keyboard shortcut
- Changing BIOS settings
- Installing the driver in the operating system
- Other solutions
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 ways 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 on Esc, although the manufacturer can position it on the second 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.
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 enabling / disabling Fn.
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 notebook computers. 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.
Function keys F1-F12 on the keyboard
Function keys or as they are also called F-keys on the keyboard are not used very often, although, by and large, it is the F1-F12 buttons that can significantly speed up a number of typical operations performed on a computer in everyday work. In my opinion, the main reason why the function keys are not used often is precisely because of their “many” functionality.
The fact is that almost all of them can work differently depending on which application or program is open on the computer at the moment. Users who are accustomed to the “one-directional” hotkeys SIMply do not want to waste time remembering how a particular F-key behaves in this case, and in total. They spend even more time :).
To correct this misunderstanding, I have compiled for you a list of the Most “common” functions performed by the F1-F12 keys in Windows on MacOS. Unfortunately, I can’t help but note that even the most “standard” functions of the function keys (for example, F1 is “help”) do NOT work in all applications. But fortunately, so far this is still more the exception than the rule.
Function keys on laptop keyboard and Fn control key.

The laptop keyboard adopts standard QWERTY key layout with the addition of dedicated function keys and an embedded numeric keypad for intensive numeric input. Your keyboard has two Windows 95-specific keys. These keys provide the ability to take advantage of many of the time-saving features of Windows 95 software.
QWERTY layout means placing alphanumeric keys on the keyboard in the same sequence as in standard typewriters. There are some keys like Scroll Lock, Print Screen, etc., whose functions may not be familiar to you. This chapter introduces some of THESE keys and discusses their function when working in the disk operating system DOS or other application programs such as word processors or database management programs.

What is needed for the function keys to work on a laptop?
It is important to understand that controlling the laptop using the function keys “F1”. “F12” is done with the help of Special programs, which the laptop manufacturers have sewn into the laptop’s native operating system. Function keys SIMplify access to these programs, make these programs invisible to the laptop user.
However, by pressing the function keys on the laptop, the user receives the Required response (in the form of connecting or disconnecting certain laptop devices, in the form of adjusting the brightness and volume, etc.) by automatically launching THESE Special Programs.
This means that if THESE Special Programs are not in the laptop, then the function keys will not work. And no settings will be made! Another confirmation of the fact that a computer is a unity of working software (i.e. programs) and working hardware.
Computer literacy with Hope. Laptop function keys F1-F12
In Figure 1, the Fn key on a laptop is highlighted in a red rectangle (left), and the function keys on a laptop that work in conjunction with the Fn key are highlighted in green rectangles.
The inscriptions applied to the special function keys in which we are talking, as a rule, have their own color (more precisely, their design) on the built-in keyboard, for example, red, blue, green (or can SIMply be surrounded by a white frame). The same color (or design) has the Fn lettering on the Fn key on a laptop. This means that these special keys only work when pressed together with the Fn key.
For example, if a red (blue, green) icon of a crossed-out built-in mouse (which means “disable the built-in mouse” Tach-Pad for a Sony laptop) is applied to the “F1” key, then to disable the built-in mouse, press the “Fn” key on the laptop, and, keeping it pressed, SIMultaneously press the “F1” key. Reverse connection of the built-in mouse is done in the same way: “Fn”. “F1”.
On different laptops, the “F1”. “F12” keys have different meanings. No standardization is applied here.
- On one laptop, “F1” can mean disabling the built-in mouse, and on another, for example, turning off the PC in sleep mode (an icon with a double or triple repeating “Z” symbol, which, according to laptop manufacturers, means the sound “Zzzz.”. in Russian it sounds “s-s-s-s.” and resembles breathing during sleep).
- The key responsible for connecting and disconnecting Wi-Fi, as a rule, has an image of an antenna emitting a signal in all directions.
- The key to increase the brightness of the image on the built-in display has a stylized image of the screen (frame), inside which is a large sun icon.
- And on the key to decrease the brightness of the screen, the image of the sun inside the stylized image of the screen is small.
Almost all the images printed on the “F1”. “F12” keys are understandable without additional explanation. And if necessary, do not neglect the instructions supplied with all laptops without exception. These instructions exist both in printed form (it is good if they are written in Russian, otherwise sometimes it can be anything other than Russian), and in the form of PDF files on a PC, located in a special folder on the C: drive (also unfortunately, these descriptions are not always made in Russian).
A SIMilar scheme for controlling a laptop using function keys is very convenient. Without them, it would be necessary to call special programs for each connection. disconnection or for each adjustment. over, not all of these programs can be found in the “Control Panel”.
Sometimes, specific programs (for example, adjusting the backlight of the built-in keyboard or controlling the battery charge in order to ensure its longer operation) are not located in the “Control Panel”. They then need to be found among the Special laptop control programs. And you need to know them.
In addition, controlling the laptop using the function keys (and with the help of Special laptop control programs) makes it possible to apply the settings inherent only to this laptop.
These settings, such as:
- Adjusting the keyboard backlight,
- Battery management system,
- Accessibility for users with disabilities, etc.)
Cannot be executed by standard programs from the Windows “Control Panel”.
Filling in the gaps. Expanding horizons!
How to dial digital codes on a laptop
Numeric codes are not directly related to the function keys of the F1-F12 laptop, however, there is a problem with entering codes for the laptop, so let’s move on to its consideration and solution.
Reader’s question: When typing, I use Alt to type numbers that are not on the keyboard: Alt0151 is a dash (not a hyphen), Alt0171 and Alt0187 are angular typographic quotation marks, which is necessary when typing typographic text. How to type these codes on a laptop?
There are full-size keyboards (Figure 2) in which the case has a small numeric keypad (partly highlighted in red and blue). Anyone who works with numbers (accountants, bankers, marketers, Excel spreadsheet users, etc.) almost always only deals with a full-size keyboard.
Using the small numeric keypad, you can enter numeric codes that cannot be entered using ordinary numbers, more about numeric codes HERE.
There are, of course, laptops with full-size keyboards (as in Fig. 2, click on the picture to enlarge). As a rule, they have a large screen, but at the same time such a laptop has a solid size and it weighs a lot. Such laptops are rare among ordinary users. Pay attention to fig. 2, that with a full-size keyboard, the laptop has Fn keys, it is absent as unnecessary.
But what about users of ordinary laptops with a keyboard that has a small numeric keypad, but need the functions of a small numeric keypad, in particular, entering numeric codes? Laptop manufacturers got out of the way by stitching additional features into other laptop keys. To enable such features, the laptop has an auxiliary Fn key (highlighted in Fig. 1 and is in Fig. 3).
As seen in Fig. 3 (click on fig. To enlarge it), each laptop keyboard has a number of keys from 1 to 9. They are in the second row, and in the first row there are function keys F1-F12. We will be interested in other numbers, which are available on laptops and are written more finely than ordinary numbers (highlighted in Fig. 3).
To dial a numeric code on a laptop:
1) find the Fn and Num Lock keys (in Fig. 3 highlighted with a red frame, they are decorated in the same style. blue and italic, but on your laptop the style may be different). Press the Fn and Num Lock keys at the same time.
At the same time, a mini-light bulb may light up on the laptop, if such an indication is provided in the laptop. Thus, you will include a small number keyboard, which laptop manufacturers “sewn” into a conventional keyboard.
2) Pay attention to the numbers from 0 to 9, which are the same color (same style) as the Fn key. On each laptop, the style of the characters with the small numeric keypad will be different, there are no standards.
In fig. 3 (clickable) small numeric keypad “hardcoded” (located) on the following laptop keys:
- The small number 0 is located on the letter M,
- Small number 1. on the letter J,
- Small number 2. on the letter K,
- Small number 3. on the letter L,
- Small number 4. on the letter U,
- Small number 5. on the letter I,
- Small number 6. on the letter O,
- Small number 7. on large number 7,
- Small number 8. on large number 8,
- Small number 9. on large number 9.
Try on your laptop entering the numbers from 0 to 9 using the small numeric keypad in a text editor such as notepad.
3) So, the Fn and Num Lock keys are pressed. the small numeric keypad is on. The numbers from it can be used as digital codes. To enter, for example, the code Alt0151,
- Press the Alt key and, Do not release it, enter the code 0151.
- That is, while holding down the ALT key, click on the numbers in turn: first on the number 0 (where the letter M is in Fig. 3). Then, Do not release ALT, press on 1 (where the letter is J), then on 5 (where the letter is I) and again on 1 (where the letter is J).
- I release all the keys. a dash should appear.
- If it didn’t work the first time, try a few more times.
4) If you no longer need the small numeric keypad, press the Fn and Num Lock keys at the same time. Thus, additional functions on the keyboard will be disabled (that is, the small numeric keypad will be disabled).
And it will be possible to use the keyboard normally to enter letters.
What if the small numeric keypad on a laptop does not work? I think that this could be if
- The Num Lock key is not turned on or something is wrongly done. Usually when you first try to learn how to use the small keyboard.
- The laptop had a reinstallation of the native operating system, wired by the manufacturer, to a non-native.
Why did the function keys stop working on the laptop?
You can accidentally or purposefully uninstall special laptop management programs. Sometimes they are, as it were, loaded in the operating system, since they can be pre-launched when the PC boots. When optimizing the load on the PC, disable “unnecessary” (from the point of view of the user who optimizes the PC) programs when loading, you can accidentally disable the “necessary” laptop control programs. By the way, this is one of the reasons why I do not like the loading optimization often advertised by some advanced users.
Special programs can be destroyed by viruses. There may be other ways to remain Special laptop management programs.
How to restore the function keys to normal operation?
Reverse recovery is possible if there is a “native” distribution of the system supplied with the laptop. Or by downloading “native” programs from the Internet, if they are available on the websites of laptop manufacturers. The latter is especially useful if the PC user changes the version of the operating system (as in the above example of replacing Windows XP with Windows 7), but does NOT use the “native” operating system that came with the laptop.
Specialized laptop control programs may require periodic updates. Updates to the special software of a laptop cannot be done in a standard way using a service updated from Windows. To update the special software of a laptop, you must also have a special program for checking and installing updates.
This program works using access to the update via the Internet. It must be run periodically (if It does not start automatically at every Windows boot) and use it to check for updates and install them. If the program allows, then it is useful to set the automatic search mode and install updates of special software for managing a laptop.
Some users connect an external keyboard to their laptop. In this case, sometimes the function keys of the laptop do not work when pressed using an external keyboard connected to the laptop via the USB port. But they can also work, that’s how lucky. That is, there is a guarantee that the function keys of the laptop will work on an external keyboard.
Summing up, we can say that controlling a laptop using function keys and Special programs, with which these function keys are “associated”, is a very convenient service from laptop manufacturers. Thank them for that! And the safety of this service is the task and responsibility of the laptop user.
It is necessary Make sure that the system on the laptop was “native”, so that all special programs are present in the PC. And so that they are “correctly” loaded when you turn on the PC. And also necessarily “correctly” updated during the entire period of operation of the laptop.
And then it will be pleasant and convenient to work with a laptop, as it was intended by their manufacturers.
In Some Secrets Of Function Keys On Laptop
As part of computer literacy, let’s talk about Special Function Keys on a laptop. With their help, you can easily and quickly manage your laptop.
Function keys F1-F12 on a laptop allow, for example:
- Connect and disconnect the built-in laptop mouse (Tach-Pad),
- Turn the Wi-Fi receiver on and off,
- Connect and disconnect an external monitor or projector,
- Adjust the brightness of the built-in display screen,
- Adjust sound, mute
- And so on.
Questions From Readers
Here are a few questions from readers of the blog with my answers, which served as material for writing this article (by the way, ask questions in the comments, if you do not find an answer to them, I will answer, and my answer will come to you by e-mail, to your E-mail ).
Question 1: While I am working on the keyboard, if I don’t see it, the cursor arrow itself runs away somewhere. Are there any commands to prevent this?
Answer: The cursor runs away on a laptop, if you accidentally and unnoticed touch the touchpad. this is the built-in laptop mouse. I disable the touchpad for this reason and use a regular mouse. In order to disable the touchpad, I have keys (first I press. Then Don’t release it, I press), you may have other keyboard shortcuts. Look at the instructions for your laptop (in paper or electronic form), it says about it.
Question 2: a laptop, there is Windows 7. Such a misfortune happened: in the lower right corner of the screen, caps lock off or caps lock on was written earlier (duplicating the indicator), but now it does not write, the indicator works, but it is not very convenient to look at it especially in a well-lit room) caps lock is on or off.
What could go wrong in the settings, and what can be done to return a text notification about the state of the caps lock mode? thanks.
Answer: Most likely, these are specific settings of your laptop. I know, for example, laptops in which the keyboard has a backlight, and it (its brightness, glow duration, etc.) is configured by a separate special program included in the laptop software package.
If, for example, you reinstall Windows and install a non-native system that came with laptops, then such specific programs disappear completely, and with them the usual conveniences disappear.
If you have NOT reinstalled the operating system, then look in the Control Panel or among the Special Control Programs for your laptop for a program that configures this service that has become familiar to you.
Question 3: Tell me, please: on my laptops, the CAPS LOCK and NUM LOCK indicators do not light up when pressed. What to do? How to fix the situation?
One of the possible reasons is non-native software on the laptop, that is, the native operating system was removed, and a foreign operating system for your laptop was installed instead.
The article is over, but you can still read:
F1 F12 keys don’t work on keyboard
If you find that your f1 f12 keys are not working on your keyboard, the first thing to do is stop panicking. This is a fairly common problem and can be easily solved.
In this article, we will show you how to fix the function keys (this is the name of the keys from F1 to F12).
Recall: the f1 f12 keys on a laptop keyboard work when you SIMultaneously press the fn key combination, the required f1 f12 key. On a desktop computer, you do not need to press the fn key for one of the f1 f12 keys to work.
Many users reported that SIMply pressing the F11 or F12 key fixes the problem that all function keys do not work. Try pressing F11 or F12, then test the rest of the function keys.
Update function key drivers
If the function key drivers are not compatible with your operating system, they may NOT work either. Thus, make sure you have the latest drivers for the function keys installed.
Open your laptop manufacturer’s website, go to the Driver Download Center and download drivers for your keyboard. Install new drivers, then restart your computer and check the f1 f12 keys.
First, take a look at your keyboard. Many keyboards have a separate key labeled F Lock or F Mode. This key is designed to lock the function keys due to which the f1 f12 keys on the keyboard do not work.
If you have one of these keys, then press it to make the function keys work again.
Install BIOS Update Driver
Please note: installing BIOS Update Driver may pose a small risk for your computer, so it is better to seek professional help.
If your keyboard f1 f12 keys don’t work, you can try installing BIOS updates. To do this, you need to download the BIOS Update driver from your laptop manufacturer’s website. We will take an HP laptop as an example.
2. Then find your laptop model.
3. Select your operating system.
4. Find and expand the BIOS section.
5. Then click “Download”.
6. When the download is complete, double-click the downloaded.Exe file to install the driver.
7. Restart the laptop for the changes to take effect and check if the f1 f12 keys work.
That’s all! We have reviewed the most popular solutions to the problem when the f1 f12 keys on the keyboard do not work.
Why does “press f1” appear when the PC boots up and how to remove it?
Faults are different. Sometimes we know the reason for the appearance of malfunctions in the PC, but it is much more “painful” for users in those cases when a properly functioning computer SIMply refuses to work normally at one point. This is especially bad when the problem is detected when Windows boots. Preventing normal startup of the OS and eliminating the cause at the software level.
A fairly common problem can be considered a situation in which the system asks us to press f1 when loading Windows (the version of the latter does not matter). The root of this problem can be different. If you understand what is happening, you will immediately understand that there are reasons to sound the alarm, reinstall the OS, or call the wizard at home. However, ignoring the situation in the future may not weakly backfire.
In this article, you will learn all the nuances of why the PC requires you to press f1. In parallel, in the text, you will come across explanations of the reasons for this phenomenon and methods for their correct elimination.
Analysis of messages above the line “Press F1
At the beginning of the article, I mentioned that the reasons for calling the deadlines before Windows boots can be different. It’s time to deal with the topic, Which are caused by problems at the hardware level. In such cases, the information in the form of text that appears along with the request to press F1 helps to identify the root of the problem. Here is a transcript of the most common term:
- CMOS Checksum Error (Bad)
Such an inscription indicates a dead battery power supplying the motherboard (it is she who is responsible for saving BIOS settings). You can also verify this by the lost time and date. It is not difficult to guess that you can solve the dilemma by replacing the battery with a new one.
- CPU Fan Error
The presence of this inscription means that the system cannot recognize the cooler cooling the processor. This can happen as a result of damaged contacts / connector, or due to dust contamination of the fan blades. We advise you to carefully examine the cooler and clean it (and other components). If this mayor does not give the desired result, it may be worth thinking about buying and replacing a faulty fan.
- Floppy disk fail
If you see this inscription with the requirement to press F1 preceding it, then the system is trying to read data from the 3.5 mm drive. In this article, we have already discussed in detail the methods of resolving this conflict in the section “Disable Floppy Drive”.
- No Keyboard Detected (Present)
Occurs when the system cannot detect the connection to the keyboard. In such cases, it is impossible to fulfill the requirements of “Press F1 to Resume” due to obvious reasons. The situation can be corrected by resetting the BIOS settings, checking the connection to the “system unit”, or buying a new input device.
- Intel CPU uCode loading error
This inscription is observed by users trying to install a new processor in a computer with an outdated motherboard. Such a conflict is manifested by incompatibility at the software level (sometimes the system SIMply will not start working with an unrecognized processor).
There are two ways out of the situation. First, you should try to flash your BIOS, update it to the most current version (in the hope of improving compatibility with new components). The procedure is not SIMple, but Armed with guides and step-by-step instructions, it is quite solvable. The second option is to buy a new motherboard. Please note that you will have to choose a board taking into account the components already available, so as NOT to face incompatibility problems in the future.
Change download priority
Sometimes, you may come across a request to press F1 after connecting several hard drives. In this case, the system may be confused which device will start first (the priority should be where your OS is installed). You can fix this by manually setting the correct boot order.
- Enter BIOS Setup (see item 1, section “Save settings”).
- Use the “right” arrow key to go to the “Boot” tab.
- Being on the line “1 st Boot Device” press “Enter”. And then specify the value “Hard Drive”.
- Press F10. By initiating a restart of the computer. The problem should be fixed on next startup.
Before proceeding to debriefing a specific problem and learning methods of how to fix a malfunction, you should understand that your computer asks you to press f1 only if there are problems at the BIOS level. This message does not in any way apply to the OS you have installed (be it Windows 10, 7, XP, or even Linux). Only the motherboard is “to blame”, or, to be precise, the system installed in it.
Most often, the message about the need to press the f1 key is encountered by users after an incorrect termination of the previous session. Unplugging your PC from power, or a power outage can disrupt your BIOS settings. The best solution in this situation is to keep the settings. This can be done in the following way:
- Start your computer. Before trying to boot the OS, enter the BIOS Setup menu (you can do this by pressing the F1, F2, F10 or Delete key).
- While in the menu, press the F10 key. And then Confirm the action by choosing “Ok”.
- At the next reboot of the PC, the annoying inscription should NOT appear.
Check hard disk for errors
Due to the work of malware, improper operation, overheating of the HDD or its mechanical damage, so-called “bad sectors”, or bad blocks, may appear on it. As a rule, the data on them can no longer be reproduced. The subsequent recording of any information on this segment of the hard disk is also impossible. If there are problems with the hard drive, it starts making sounds, what they mean can be read in a separate article.
Such a phenomenon can disrupt the operation of the system, up to the request to press F1 on the keyboard while starting the PC. The reason for this is SIMple: a system file could be located on one of the bad sectors. To identify the presence of “problem areas”, we advise you to use the Specialized utility. The Victoria and Crystal Disk Info program can help detect broken sectors. Let’s analyze the second in more detail. Download the utility and read about its installation and use, you can follow the link above.
- You can also download the program on the developer’s website. https://crystalmark.info/en/software/crystaldiskinfo/
- We open the application. When you first start it, it automatically starts working, providing an informative summary of the state of your computer’s components. The status “Good” in the technical status section reports on the normal functioning of my PC. In case you run into problems (including in the presence of “broken sectors”), in the panel below you will see a red circle indicating a malfunction of a specific component. In the presence of bad blocks, the items “unstable sectors” and “Unrecoverable sector errors”.
In cases where the PC does not start after pressing the requested key, we recommend that you boot the OS in safe mode and carry out the necessary diagnostics.
Disable Floppy Drive
Quite often the request to press F1 is accompanied by the message “A: Driver Error”. This may be a prerequisite for several processes at once, one of which is an unauthorized search for a Floppy drive on your PC. over, it is found even on those computers where the drive for reading 3.5 mm floppy disks is already in sight of comments.
There are two ways to cope with the problem at once. First, thanks to the instructions described above, you can change the boot priority by changing the value of “Floppy Drive” to “Hard Drive”. The second option is tied to the complete disabling of the function and BIOS revision.
- We start the computer. Move to BIOS Setup (see item 1, section “Save settings”).
- Depending on the type of BIOS, we perform the following actions:
- In the AMI, look for the “Main” section. Use the arrows to select the “Legacy Diskette A” segment. Press “Enter” to open the function control window and select “Disabled” in the next window that appears. Save the result by pressing the F10 key.
- In the Award BIOS, we are interested in the Standard CMOS Features tab. And in it the parameter “Drive A”. We set the value “None” and successfully exit the menu by pressing the F10 key.
Reset BIOS settings
Sometimes it is not enough to save the BIOS settings after an incorrect shutdown of the PC. The ill-fated inscription does NOT disappear, and the patience from constant requests to press F1 is already at the limit. Resetting BIOS settings is considered to be effective in fixing the problem in such cases.
The methods, thanks to which this can be achieved, and do not require the use of professional skills. You can reset the settings either programmatically (in the BIOS Setup menu, or by entering certain commands in the command line), or by manipulating the computer hardware. You can read more about troubleshooting options in the dedicated article, linked from the link above.
Replace power supply
Unstable power supply to the computer can become a prerequisite Not only for the appearance of an ill-fated inscription before launch, but also for serious breakdowns, which are fraught with expensive repairs, or even with the purchase of new components.
First of all, check the power supply. Bare sections of the cable, damage to the plug inform us about the need to replace the power supply connection cord. With proper skill and the presence of the required equipment, you can check the operability of the problem power supply on another computer. Experts, in such cases, use a multimeter (aka “tester”), or Man-made jumpers. However, I warn you that without the necessary knowledge and experience, such “intervention” is fraught with health risks.
If you find any malfunctions, we advise you to eliminate them immediately, or think about buying a new power supply with its further replacement.
As we could figure out, the alarming message for many of the need to press the F1 key while starting the computer is a signal for users to be extremely careful. In the early stages, it is extremely important to find and eliminate the cause that caused this requirement. Remember that even the smallest mistake can become a prerequisite for a serious problem and the money that follows it is spent.
