How to call BIOS without a keyboard. How to enter BIOS - methods and keyboard shortcuts

Detailed material about BIOS, if you still do not know what it is, you can find on our website, or simply by clicking on the link. At the very beginning of this article, we talked about how to enter the BIOS, while you may notice that this procedure can only be carried out using the keyboard. Of course, all this is good if you have a keyboard and it works, but there are times when it is broken or USB keyboard support is disabled in the BIOS. In such cases, things will be a little... more complicated. Let's see if it is possible to enter BIOS without a keyboard, and if so, how and in what cases?

USB issues

Let's start with the fact that in the BIOS settings it is possible to enable / disable support for keyboards with USB plugs. In this case, of course, you need to somehow enter the BIOS and change the menu item responsible for initializing USB keyboards to a value opposite to the current one. This is where replacing your USB keyboard with one with a PS/2 connector will help. Looking at the screenshot, you will immediately understand what kind of connector it is.

It is important to consider here that when a keyboard with a PS/2 connector is connected, the computer initializes it only the next time it is started.

After entering the BIOS, find the menu item called USB Keyboard Support (see screenshot below) and set the value of this parameter to Enabled.

Ready. Save the changes and restart the computer. Now your USB keyboard will work.

An alternative solution to the problem with USB ("surgical" intervention)

Of course, you may not have a keyboard with a PS / 2 plug, and you have nowhere to get it. In this case, you can use another method, namely, resetting the BIOS settings to factory settings.

So, turn off the power to the computer, open the side cover system block and look inside. You need to find the trigger that says CCMOS (see screenshot below).

Switch it to another position for 10-20 seconds, and then return to its original position. After these steps, turn on the PC. The USB keyboard should work successfully.

For owners of some laptops

In rather rare cases (why is not clear), laptops have special buttons for entering the BIOS. By pressing it, the system will go into BIOS mode without first rebooting the device.

If you have such a button, feel free to use it.

Variant for Windows 8.1 (for BIOS UEFI)

If everything is quite simple with relatively old computers, then some problems may arise with new models. We are talking about updated version BIOS called UEFI. And if it so happened that your PC has this very UEFI, while you are using the Windows 8.1 operating system, then there is a separate way for you to enter the BIOS.

In this simple way, you can enter the UEFI BIOS in Windows 8.1 without using the keyboard.

Outcome

Here are a few ways that will help you solve the problem of entering BIOS without a keyboard (or almost without it). If none of the methods brought results, then we recommend taking the system unit of your PC to service center, where they will tell you exactly what the problem with entering the BIOS is. That's all we have. Ask your questions in the comments if any of the methods was not clear to you or something does not work out for you. Good luck!

Enter BIOS without keyboard

To enter the BIOS, you need to use special key or a combination of keys on the keyboard. But if it does not work, then enter standard method will not work. It remains to either find a working keyboard model, or enter directly through the operating system interface.

We enter the BIOS through the OS

It is worth understanding that this method suitable only for the most modern versions of Windows - 8, 8.1 and 10. If you have some other OS, you will have to look for a working keyboard and try to enter in a standard way.

The instruction for logging in through the operating system looks like this:

Unfortunately, this the only way enter BIOS without keyboard. Also, some motherboards may have a special login button - it should be located on the back of the system unit or next to the keyboard for laptops.

Is it easy to enter BIOS?

"The Russian man is famous for his ability to find a way out of the most difficult situations, but he is even more famous for his ability to find an entrance there."

Stas Yankovsky

It is unlikely that there will be such a computer user who would never need to use the program in his life. BIOS Setup or, as they say in computer jargon, enter the BIOS. There can be many reasons for this - from the need to set the necessary parameters for the operation of memory, processor and drives to monitoring the status of equipment on a PC or laptop or setting a password to enter the system or Setup itself. And therefore, the question of how to enter the BIOS is probably not an idle one for most readers.

The main option to enter the BIOS

In order to enter the BIOS, you just need to press a certain key when the computer boots. Usually this key is the Del key, but there are other keys or key combinations. How to enter BIOS if you do not know the right key?

First of all, it is advisable to look at the documentation for your computer, especially if you are a happy owner of a laptop, since laptop manufacturers do not always comply with this standard, and in order to find out how to enter the BIOS by trial and error, you will have to try too many keys. You need to press the necessary keys at the moment when information about the computer appears on the screen.

Typically, this start screen shows information about the key that you need to use to enter the BIOS on desktop computer or laptop. If you do not have time to consider this information, then use the Pause / Break key - this will stop the system from loading. To resume the download, you usually need to press the Esc key.

Standard keys with which you can enter the Setup of various BIOS manufacturers:

• AMI - Del, F2
• Phoenix - Del, Ctrl-Alt-Esc, Ctrl-Alt-S, Ctrl-Alt-Ins
• Award - Del, Ctrl-Alt-Esc

Possible problems when entering the BIOS

Very often, people make the following mistake when they try to enter BIOS Setup - they press the key at boot too late, when the start screen has already disappeared and has been replaced by a picture Windows boot or operating system selection menu. If this happens, then pressing the desired key is already useless - you can no longer enter the BIOS. How to run BIOS in this case? You will have to reboot the system again. Therefore, it is best to keep the desired key pressed all the time when rebooting. This will not harm the computer, but you will not miss the moment you need and will automatically enter the BIOS.

What is the best way to enter BIOS - during a hot reboot with the Ctrl-Alt-Del keys or by turning the system unit on and off? It’s easier, of course, to enter the BIOS during a hot reboot, but there is such a situation when some system utility installed in operating system, intercepts the Ctrl-Alt-Del key combination and does not perform a normal reload. Therefore, it is better to still use Reset.

The question of how to open BIOS on a laptop usually causes the most difficulties. Restarting the system on a laptop usually happens very quickly, and the user is shown a minimum of information on the screen. Therefore, it can be especially difficult to catch the right moment to launch BIOS on a laptop. You might think - what's the big deal - is it enough to hold down the Del key? But no, for most laptops, this key does not work as a pass to the Setup program. Sometimes it is possible to peep the desired key in the bottom line. But if you still didn’t manage to find out the key, then to solve the question of how to enter BIOS on a laptop, it’s best to refer to the documentation for the laptop model you need.

A lot depends on the keyboard.

There may also be such a situation that you cannot enter the BIOS by pressing a certain key combination simply because the keyboard is faulty or you connected it poorly. This situation can happen, for example, if you want to enter the BIOS on a new system unit. So instead of sitting around wondering "why can't I get into the BIOS", sometimes it's good to just check if your keyboard is okay?

Sometimes, by the way, it happens that you use a USB keyboard - despite the fact that the BIOS does not support USB mode in boot mode or such an option is disabled in it. In this case, it makes sense to change the keyboard, for example, to a keyboard with a PS connector.

What to do if the password interferes?

Sometimes it happens that the user cannot enter the BIOS if a password is set to enter the BIOS that he does not remember, or the password was set by someone else. A similar password is sometimes set by a company that sells and configures computer equipment. If you want to reset it and be able to freely enter the BIOS, then you will have to open the computer case and reset the BIOS CMOS memory by installing a special jumper to clear the memory on the motherboard or temporarily removing the BIOS battery. You can find out how these measures are best carried out in the documentation for the motherboard.

Conclusion

BIOS Setup is very often the first program that a computer user encounters. Therefore, manufacturers computer technology usually they do it so that the question of how to start the BIOS does not overshadow the life of an inexperienced user. We hope that you will not have any problems about how to get into the BIOS on a desktop computer or laptop. If, nevertheless, they arose, then we hope that this article helped you solve them.

How to enter BIOS on a computer

Comments on the entry: 2

BIOS is a basic system or set of firmware needed to configure the hardware on the motherboard (BIOS), most often used to configure device boot, set the time, configure the processor, cooling, memory, disable and enable some devices. The task of the BIOS is to prepare and test the equipment for the subsequent boot of the operating system or device that has an installation program or boot of the operating environment (such as an operating system on a disk).

Under in the usual way enter the BIOS is understood as: pressing a certain key or key combination on the keyboard during power-on or reboot, before the start of the operating system itself Windows systems. It should be mentioned that in new versions of the operating system (if they are installed in UEFI mode, Windows 8, 8.1, 10), it is possible to enter the BIOS after the operating system has loaded.

To enter the BIOS, you usually need:

• View keyboard shortcuts for your motherboard. On the Internet you can find an electronic manual for your motherboard.
• Or usually when you turn on the computer or when you reboot, prompts pop up on the screen regarding the BIOS entry keys. If the operating system starts immediately, then the article below says how to disable fast loading or enter the BIOS from the operating system without using the keyboard and key combination when logging in.

Most often in BIOS, keys such as Delete are used, less often Ctrl + Alt + Esc, F2 more often on laptops, Delete.

How to log in through Windows

As previously mentioned in new versions of the Windows operating system (Windows), it is possible to enter BIOS from the system itself. Yes, yes, you understood everything correctly. You can go to basic system I / O after the operating system is loaded without a keyboard, not when the computer is turned on, but after the operating system is loaded.

For this you need:

1. Windows 10, Windows 8, 8.1, Windows Server 2012, Windows Server 2012 R2 must be installed in UEFI mode (usually the default).
2. Go to settings through the start menu. Or similar in others Windows versions(Examples on Windows 10)

In the next menu "Options" of the Windows operating system. You should select the recovery tab, the left side of the window. In the "Recovery" tab that opens. Find "Special Boot Options" and below the "Restart Now" button

Finish after the steps have been taken. Windows operation and the "Select Actions" window will appear. In this blue window, select "Diagnostics Restore your computer, reset your computer, or use additional tools."

Choose built-in options software UEFI, then select reboot and after reboot, instead of booting into Windows, BIOS will appear. Let me remind you that the menu item “UEFI Firmware (Software) Settings” will be available if Windows is installed in UEFI mode.

If someone had a question: “How to enter BIOS using the command line?”, Then I want to correct it a little. From the command line, you can only call up the blue menu, which, as indicated above, in the previous paragraph of our article, and then, if the operating system is installed accordingly, you need to launch the command line for this.

To do this, you can enter "cmd" or "command line", you can not enter completely.

Press Enter and a command prompt window opens.

Copy the following name of the executable file in the system folders (if no specific path to executable file) program or enter it manually:

shutdown.exe /r /o

If you're wondering what the /r and /o keys mean. (The keys are the parameters to the program that is launched via the command line written through a slash, in this case the key "r" and "o")

If you want to know what these keys are, type "help shutdown". After entering this command at the command line and pressing the Enter key on the keyboard, a prompt will appear explaining how to use the shutdown command.

From which we learn, for example, that the / o parameter is a transition to the advanced boot options menu and restarting the computer. And also that this option must be used with the /r option.

So it's simple alternative way open the blue menu mentioned in the previous paragraph. Only for this will be used not start and GUI toolbars, and the command line and the shutdown application with parameters.

What to do if you can not enter the BIOS?

Because of what, the reason for the inability to enter the BIOS may arise (UEFI - in fact, it should be called, but out of habit everyone uses the word "BIOS").

1. First of all, this is a quick start of the Windows 10 operating system, which can be disabled, because of it they do not have time to quickly press the BIOS entry key. For owners of solid state hard drives this function is very convenient, it allows you to quickly turn on the computer after pressing the power key, but if you need to enter the BIOS, you will either have to turn it off or go through Windows.

In the search near the start, type "Power"

Press Enter. Go to the tab "Actions of the power buttons" And if there is a checkmark "Enable fast startup", then remove it. Now you will have time to press the button to enter the BIOS.

2. Other reasons may be the wrong login button or keyboard shortcut.

3. If the computer does not start due to the parameters set earlier in the BIOS, then it can be reset by pulling out the battery for a while. This will reset the BIOS settings to factory settings and possibly give access to it.

4. If the monitor does not display a picture for a long time when you first turn it on, it may take this time to pass the BIOS screen and start loading Windows.

The keyboard does not work in BIOS: causes of malfunctions and their elimination

The problem that the keyboard does not work in the BIOS, users usually notice when reinstalling the operating system, when it is necessary to set the boot priority, or in case of a change advanced settings primary input/output system. What is the reason for this phenomenon and how to deal with it, now it will be considered. Just want to note that not everything is so bad. There are several basic methods that allow you to solve the problem within a few minutes. Let's consider them.

Keyboard does not work in BIOS: reasons

Many users pay attention to the fact that in a normally functioning operating system, although such situations are observed, they are very infrequent. For the most part, this concerns just the BIOS.

Among the main reasons for the appearance of such a situation, most experts distinguish the following:

• physical damage to plugs and wires;
• incorrect connection;
• old computer no connected device support;
• incorrect BIOS settings.

Issues related to physical defects or damage will not be considered at this time. As a last resort, if the keyboard does not work in the BIOS, you can check the operability of an external type device of the PS / 2 or USB standard quite simply by connecting it to another computer terminal. If everything is in order on it, the reason must be sought in your system unit (more precisely, in the slots and ports to which you are connecting).

What to do first?

As for troubleshooting, first of all, you should check the correct connection.

In the case of USB keyboards, it is quite difficult to make an incorrect connection through the corresponding port (although sometimes it can be said that the keyboard belongs to the USB 3.0 standard, but is connected to the USB 2.0 port).

But most often the appearance of such a situation is more typical for old-style PS / 2 keyboards. It is necessary to make the connection taking into account the fact that the colors of the keyboard plug and the corresponding socket must match (they are purple). However, in this case it is quite difficult to make a mistake.

How to enter BIOS (keyboard not working)?

When you try to configure the parameters of the primary system, which can very often be the cause of failures, the question of access to them arises along the way, because in most cases you cannot do without a keyboard to call the BIOS or navigate through the settings sections.

But there is a solution. For example, we have a situation where the keyboard on a laptop does not work in BIOS. You can enter the settings system in several ways. Some laptop models are initially equipped with special buttons on the panel, with the help of which the BIOS settings section is called up. In particular, this applies to Lenovo products, Sony VAIO(ASSIST button), etc.

The second access option in the event that the keyboard does not work in the BIOS is to connect its external analogue via the USB port. But here you need to remember that it is advisable to connect an external keyboard without power, and only then turn on the device for boot.

Reset

The previous solutions can be called universal in some sense, however, and they may not give the desired result. This can be observed when the USB keyboard does not work in BIOS. This problem is only due to the fact that some kind of failure occurred in the system itself.

In this case, a full reset should be performed. set parameters. Any, even an old stationary type computer, allows you to get to the motherboard on which the CMOS battery is installed. You just need to pull it out of the socket for a few minutes, insert it back and try to enter the settings by turning on the terminal to boot.

Setting the correct parameters

But even here there are pitfalls. In the case of USB keyboards, the problem may be that support for such devices is disabled on the primary system itself.

In this case, you will have to connect a PS / 2 keyboard or, if possible, enter BIOS on a laptop by pressing a special button, then find parameters like Legacy USB Support or USB Keyboard Support and look at the set value. If this is indeed the reason, it will be set to Disabled. It needs to be changed to Enabled and save the changes on exit (F10, Y). A reboot will follow. Perhaps this is the only way to fix the problem.

What else could there be?

According to reviews, sometimes the failure of the keyboard may be due to damage to the slats random access memory, malfunctions in the operation of the power supply, shorting of some contacts directly on the motherboard, malfunctioning ports, etc.. Here without complete diagnosis the whole system is indispensable.

Finally, there may also be a problem with the BIOS system itself, which consists in disrupting its operation or becoming obsolete. In this case, you will have to do a complete flashing, but this process is unsafe, and without special knowledge, an ordinary user can cause irreparable damage to the computer, as a result of which the PC will stop working altogether.

Instead of total

Based on the foregoing, we can conclude that, regardless of the current situation, apart from physical damage or defects, the problem of the inoperability of the keyboard and access to the primary system is solved quite simply.

But there can be many reasons for this phenomenon. And they are not always associated exclusively with defects of a physical nature. In most cases, for the same USB devices, simply enabling support or doing a master reset is enough. It helps 99 times out of 100.

Finally, speaking of the problem global character, when the keyboard does not work at all, you can identify it immediately on the welcome screen when you turn on the computer terminal (it will be reported that the keyboard is missing). In this case, you will either have to check the correct connection, or use the methods proposed above, up to replacing the failed device with a new one.

Hello dear readers. Today's article is dedicated to the topic "Keyboard not working in bios".

This problem occurs quite often among many computer users. There are even moments when people with 10 years of experience with a computer encounter this problem for the first time and do not know how to solve it.

The keyboard is a necessary part of the "input output devices" and therefore any work with a computer where the mouse is not supported is done using the keyboard. There are some of the most common reasons why these problems occur.

All listed methods based on the fact that you are using a fully working keyboard.

What to do if the keyboard does not work

If you were not careful, you could bend the legs at the PS / 2 keyboard connector. The plug itself is usually purple..

USB keyboard not working in bios

Most often, this situation occurs when you connect the keyboard to an old computer.

The BIOS of old computers is not USB support ports, but only PS / 2. Therefore, you need to find a keyboard with a similar connector or buy an adapter. It's hard to find a PS/2 keyboard these days though.

If your computer is new or you are sure that your BIOS supports USB keyboards, then you need to check whether the option “Legacy USB”, “USB keyboard” or “USB Function For DOS” is enabled, if disable is written there, you need to set the enable value, i.e. e included.

Be sure to save your settings when you exit the BIOS. Otherwise, all your changes will lead to nothing.

Keyboard not working when selecting OS

If the keyboard works in the OS itself and BIOS, but does not work when choosing to boot the operating system, you need to update the OS bootloader, but it's better to use the Grub bootloader that is installed when you install Unix.

To update Windows bootloader you must have a disk with the operating system installed. Your installed OS must have full functionality. This article will show you how to restore the bootloader in Windows.

Alternative methods.

A few more tips that help solve the problem with the keyboard, but they are used very rarely.

If this article did not help solve your problem, then ask questions in the comments and we will try to help you.

Question from user

Hello.

Tell me with one problem: I just can’t enter the BIOS, I have already tried all the buttons (DEL, F2, ESC, F12, etc.) - the computer does not respond to them. The motherboard is GIGABYTE GA-H11 (as it is written in the specification for the PC). What can be done?

Hello.

It is difficult to name an unambiguous reason (by the way, you indicated the model of the motherboard incorrectly). Most often, it is not possible to enter the BIOS due to a "not working" keyboard or an incorrectly selected key. Below is a list of everything you need to pay attention to...

Note: if you need to enter the BIOS to install a new OS, then this can be done in another way (see paragraphs 4, 5 below) ...

What to do if the computer does not enter the BIOS / UEFI

Key and its pressing time

And so, the first thing you should start dealing with this problem is to clarify the key to enter the BIOS. In the vast majority of cases, the key is used for this. DEL(for the board from GIGABYTE including). A little less often are the keys F2, ESC, F10, F12. See the instructions below, there are buttons for different manufacturers.

To help! Hot keys to enter the BIOS menu, Boot Menu -

Also important is one moment: BIOS / UEFI loading can be so fast that you can simply not have time to press the desired key. Therefore, try another option: when the PC / laptop is still turned off, hold down the entry key (ESC, for example), and then turn on the device (do not press the key until entering the BIOS!).

Hold down the key to enter the BIOS (for example, ESC) and turn on the device (laptop)

There is an option to "get" into the BIOS without pressing keys at the boot stage...

If you have a relatively modern computer/laptop with installed Windows 8/10 - then you can enter the BIOS through the OS interface.

First you need to open the section "Restoration" in system settings. Next, restart the computer through special boot options (see screenshot below).

Then open the section and click on "EFI Built-in Options" (see photo below). The computer will then restart and the BIOS window will open automatically...

Keyboard model and port used

Now very popular wireless keyboards. Everything would be fine, but a number of models simply do not work until Windows is loaded (the same can be said about some USB keyboards connected via various adapters ...).

Here's a simple tip: have an emergency PS/2 keyboard (it should definitely work). If you have a USB keyboard, then there are small adapters for it (USB to PS / 2). It is also worth trying to connect the keyboard directly to the USB ports located on the back of the system unit. (if connected to USB 3.0, try USB ports 2.0) .

Reset BIOS settings

In some cases, fixing the problem helps in default. To do this, you can use two methods:

By the way! After such a procedure (even if you still can't get into BIOS) most likely its settings have been reset. And this can, for example, allow you to run Windows installation from a bootable flash drive/DVD (because by default, in many BIOS versions, the first boot device is a CD / flash drive, and then - HDD) .

❺

Shutdown hard drive

In some cases, due to a failed hard drive, its initialization is delayed (sometimes it even leads to a PC freezing). Of course, this point can also be the cause of the problem in question...

What can be done: try to disconnect all drives from SATA, USB, M2 PC ports (flash drives, hard drives, solid state drives etc.). Ideally, leave the keyboard and monitor alone, then reboot the device and try to enter the BIOS.

By the way! If you need to enter the BIOS to install the OS, then you can try formatting the hard drive on another PC, and then connect it to the current one. Thus, Windows will not be launched from it and the PC will automatically try to boot from the connected installation flash drive (CD). At least that's true for the default BIOS settings...

BIOS update

If all the previous steps were unsuccessful, it may be worth updating the BIOS. Moreover, it is not at all necessary to upgrade the version - you can install something older (note: not always a new version works more stable than the current one).

Modern devices allow you to run a BIOS / UEFI update directly from under Windows. The whole update usually comes down to downloading and running an EXE file (like any other program), and after that the PC / laptop will reboot and update the BIOS on its own (automatically, without your participation).

Of course, the method is relevant for those who already have Windows on the disk. More detailed instructions below.

How to update the BIOS of a laptop (using HP as an example) -

Successful work!

The BIOS is a collection of firmware that regulates the operation of all devices and the loading of the operating system. Essentially, this the most important component of any processor. The BIOS is located on the motherboard because motherboard is responsible for managing all computer devices.

In certain situations, there is a need to enter the BIOS. There are many ways to do this, both with and without input devices (keyboards).

We will tell you how to enter the BIOS if the keyboard does not work.

Dedicated login button

To enter the BIOS in modern laptops (for example, Lenovo brands) there is a special button on the keyboard. It allows you to quickly navigate to the settings without requiring a reboot..

However, not all laptops have this button, but in personal computers she is a rarity. But this is the most effective way to enter the BIOS without touching the keyboard.

IMPORTANT! Personal computers have a button located on the case reset. In order to bring down BIOS settings, you must turn off the computer and hold down the RESET button for five seconds.

Forced cleaning with battery removal

On devices that do not have a special button for quick access to the BIOS, you must perform a forced cleaning. It is done by removing the battery.

Algorithm for performing forced cleaning

• We de-energize the computer. To ensure that the capacitors are completely discharged, you need to hold down the power button several times.
• After that, we find a battery in the block (or inside the laptop case), which looks like a coin.
• We carefully pull it out.
• After five seconds, insert the battery into place with the same side.

After these steps, the BIOS settings will be reset, and the keyboard will work again.

How to enter BIOS in Windows

For operating rooms Windows systems 8 and Windows 10, there is another way to enter the BIOS settings - using the mouse.

This requires the following steps.

• In "Settings" select "Update and security".
• Then open the "Recovery" item and select the "Special boot options" menu. Click on "Restart Now".
• After the reboot, a menu for selecting actions will appear. Click on the "Diagnostics" option.
• Next, go to "Settings".

Using this method, you can easily start the BIOS without using the keyboard.

Alternative method to enter BIOS settings

In addition to the above methods, there are more methods that will help you reset BIOS to factory settings without using the keyboard.

Jumper manipulation

To perform a factory reset in this way, follow these steps:

• Disconnect the computer from power.
• Open the cover of the system unit and look for the trigger (Clear CMOS). We change its position for a while (from 10 to 20 seconds).
• After this time, we return it to its original position.

When if no such trigger was found, it means that you have two contacts. Therefore, to perform this manipulation use a conductive tool(preferably with a screwdriver). It is required to clamp the contacts for approximately 20 seconds. After that, just turn on the computer and make sure that the keyboard works.

Those users who have ever tried to enter BIOS Setup are well aware that this operation requires an input device such as a keyboard. Therefore, the situation when you urgently need to enter the BIOS, and at the same time you find that the keyboard connected to the computer does not work at the time the system boots, can hardly be called pleasant. Is it possible to resolve this situation and enable keyboard input when the computer boots?

If the keyboard that you use to enter the BIOS was not connected to the computer before the moment you decided to enter the BIOS, then most likely the keyboard is not working for a reason associated with it. This can be either a malfunction of the keyboard itself, or its poor connection or a malfunction of the connector to which it is connected.

However, another situation is much more common - the keyboard that you use to enter the BIOS works fine in the operating system, but when you enter the BIOS it does not work. In this case, there can be no talk of a malfunction of the input device itself. Most likely, in this case, you are dealing with wrong settings options in BIOS. For example, in the BIOS, support for devices connected to USB port. There may also be a conflict with some other device connected to the computer.

Problem Solving Methods

If the keyboard you have chosen to enter the BIOS is used for the first time, then, first of all, when faced with a situation where keyboard input does not work, you need to check the operation of the device by connecting it to another computer.

If you have no doubts about the performance of the keyboard, then you can try connecting a different type of keyboard to your computer. That is, if you use a keyboard that connects to the USB connector, then you can take a keyboard that connects to the PS / 2 connector. Or vice versa, if the computer does not load the BIOS using the PS / 2 keyboard, then you can try connecting USB keyboard. In most cases, this option resolves the issue.

Also, to eliminate the possibility of a conflict between the keyboard and another USB device, you can try to disconnect all other devices connected to USB connectors. Theoretically, there may be a conflict between a PS / 2 mouse and a PS / 2 keyboard, so in this case it also makes sense to disable the mouse.

However, if all of the above methods do not help enable keyboard input, then most likely you will need to reset the BIOS settings to default settings. This is done by removing the battery on the motherboard from its slot, or by installing a special jumper. Learn more about how to implement this operation, we wrote in a separate article.

After you manage to enable keyboard input and you enter the BIOS, do not forget to check BIOS settings connection related external devices so that this situation does not happen again in the future. For example, in BIOS there are options similar to the USB Keyboard Function options that block the ability to connect USB input devices. If this option is disabled for you, then it will need to be enabled.

Conclusion

The situation when keyboard input does not work when booting the computer and entering the BIOS can be encountered quite often. However, in most cases the user can decide this problem on their own. As a rule, the situation is due to the fact that the ability to connect peripheral devices is blocked in the BIOS. In most cases, the problem can be solved by connecting another keyboard to the computer that is designed for an alternative interface - PS / 2 instead of USB or USB instead of PS / 2.
