Those users who have at least once tried to enter BIOS Setup know very well 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 discover that the keyboard connected to the computer does not work when 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 you use to enter the BIOS was not connected to the computer before you decided to enter the BIOS, then most likely the keyboard is not working for a reason related to itself. This could be either a malfunction of the keyboard itself, a 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 entering 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 incorrect settings of options in the BIOS. For example, support for devices connected to the USB port may be disabled in the BIOS. There may also be a conflict with some other device connected to the computer.
Methods for solving the problem
If the keyboard you have chosen to enter the BIOS is being 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 functionality of the device by connecting it to another computer.
If you have no doubts about the functionality of the keyboard, then you can try connecting a different type of keyboard to the computer. That is, if you use a keyboard that connects to a USB connector, then you can take a keyboard that connects to a PS/2 connector. Or vice versa, if the computer does not load the BIOS using a PS/2 keyboard, then you can try connecting a USB keyboard. In most cases, this option helps resolve the problem.
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 the USB connectors. Theoretically, there could be a conflict between the PS/2 mouse and the PS/2 keyboard, so in this case it also makes sense to disable the mouse.
However, if all the above methods do not help enable keyboard input, then most likely you will have to reset the BIOS settings to default settings. This is done by removing the battery on the system board from its socket, or installing a special jumper. We wrote more about how to carry out this operation in a separate article.
After you manage to enable keyboard input and you enter the BIOS, do not forget to check the BIOS settings related to connecting external devices so that a similar situation does not occur in the future. For example, in the BIOS there are options similar to the USB Keyboard Function option, which block the ability to connect USB input devices. If you have this option disabled, you will need to enable it.
Conclusion
It is quite common to encounter a situation where keyboard input does not work when the computer boots and enters the BIOS. However, in most cases, the user can solve this problem on his own. As a rule, the situation is due to the fact that the BIOS blocks the ability to connect peripheral devices. In most cases, the problem can be solved by connecting to the computer another keyboard designed for an alternative interface - PS/2 instead of USB or USB instead of PS/2.
When you turn on the computer, if the boot selection window appears, the keyboard does not respond to key presses and it is impossible to select. The same thing happens when you need to boot from the installation disk when you are prompted to press any key or select the disk from which the system will boot. Tell me what could be the reason. The keyboard works fine in Windows. With respect, Nicholai.

Hello. I haven't used a computer for more than six months. Then I decided to turn it on, but it didn’t load. It doesn't even reach the BIOS. In this case, the keyboard does not work and the mouse lights up but does not respond. I tried both USB and SP2 keyboards and none of them worked. What could be the reason and how to fix it?

Hello. This is my situation. The BIOS crashed, when loading it reaches the hpa bios not available moment and starts loading the previous BIOS version and then cuts off. I completely reset the BIOS by closing the CLRTC and removing the battery. Then, when you turn it on, a window appears with three items, reset, return to the previous version and a hundred more. The checkbox is “return to previous version”. I am given 15 seconds to choose. This is where I ran into a problem. Can not choose. The keyboard doesn't work. Neither USB nor PS/2. At home there are 2 working keyboards. Despite the fact that when the computer is turned off, you insert PS/2, the keyboard blinks, but when turned on it does not blink and does not light up. What could be the problem? Thank you.

Good afternoon. I have an ASUS laptop. A very old model of hard drive has an ATA interface. OS - Windows XP. Stopped loading. More precisely, the download reaches the “User” and “Password” window. Because There is no password, press Enter and the download continues. Now the laptop does not respond to key presses (including on an external USB keyboard). It is impossible to enter the BIOS because... the keys do not respond. There is a solution?

Motherboard Asus P5LD2 SE The situation is as follows: All keyboards work fully until entering the BIOS, as soon as I entered the BIOS it doesn’t work at all! Even CTRL+ALT+DEL (to restart the computer, it feels like the computer is completely frozen in the BIOS) All usb sources I turned it off, it doesn’t help! What can you tell me, I really need to get into the settings! But it worked without problems (even I updated the BIOS, took out the battery to reset it to default, it didn’t help!)

Hello dear readers. Today's article is dedicated to the topic "Keyboard doesn't work in BIOS".
This problem occurs quite often among many computer users. There are even times when people with 10 years of experience working with computers 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 the computer that does not support a mouse is done using the keyboard. There are several most common reasons why these problems arise.
All of the above methods are based on the fact that you are using a fully working keyboard.
What to do if the keyboard does not work
If you were careless, you could bend the legs of the PS/2 keyboard connector. The connector itself is usually purple.
USB keyboard does not work in BIOS
Most often, this situation occurs when you connect a keyboard to an old computer.
The BIOS of older computers does not support USB ports, but only PS/2. Therefore, you need to find a keyboard with a similar connector or buy an adapter. Although nowadays it is already difficult to find a keyboard with PS/2.
If your computer is new or you are sure that your BIOS supports USB keyboards, then you need to check whether the “Legacy USB”, “USB keyboard” or “USB Function For DOS” option is enabled; if it says disable, you must set the value to enable, i.e. e included. 
When exiting the BIOS, be sure to save your settings. Otherwise, all your changes will lead to nothing.
Keyboard does not work when selecting OS
If the keyboard works in the OS itself and the BIOS, but does not work when you select to boot the operating system, you need to update the OS bootloader, or it is better to use the Grub bootloader, which is installed when installing Unix.
To update the Windows boot loader, you must have a disk with the operating system installed. Your installed OS should have full functionality. This article explains 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.

For the Windows operating system, one of the most important parameters is the BIOS. What is its essence? BIOS stands for “basic input/output system”. This concept can be translated as “basic input/output system”.
This system is formed by a certain set of chips located on the motherboard and system software. Its task is to check and configure the hardware of a Windows computer before the system itself is launched. In other words, the BIOS precedes the loading of the operating system and helps it do so without failure.
In this regard, entering the BIOS occurs, naturally, before loading the operating system itself. This input is needed in order to change or configure certain PC parameters. It may also be needed when determining priorities in loading data from a flash drive, disk or other media. Such a need may arise, for example, when installing Windows directly from some media.
The traditional way to enter the BIOS is from the keyboard using certain keys, however there are situations where this is not possible or desirable. Then users need access without using a keyboard.
How to enter the BIOS
When the computer first turns on, as a rule, the screensaver of the manufacturer - either the motherboard or the laptop - is lying on its monitor. At this moment you should enter the BIOS. This occurs by pressing a specific key or set of keyboard keys.
The set of such keys for starting the BIOS can be very different. Possible options depend on the type of motherboard and BIOS developer. Additionally, desktop PCs and laptops typically use different keys.
If you know the key combination, the situation seems simple and clear. But it is not always possible to use the keyboard to enter the BIOS. This happens when:
The keyboard itself is faulty
- there is a malfunction in the connectors of the keyboard or system unit itself,
- the BIOS settings are such that it does not support a USB keyboard.
IMPORTANT! In the first two cases, the action algorithm is simple and accessible to every user. You just need to replace the keyboard with a working one or check the condition of the cables/connectors and replace the faulty ones.
If the BIOS itself does not support a USB keyboard or such support is disabled in the system settings, then there are also ways to solve the problem. You can use common adapters from a USB keyboard to the PS/2 port that is available on your PC. Or you can simply connect a keyboard with a PS/2 connector.
It may also be necessary to enter the BIOS not at an early stage, before loading Windows, but immediately while the loaded operating system is running. The user may well need to perform some actions in the BIOS.
This step is only possible if the computer has a UEFI BIOS version installed. It works in the following OS versions - Windows 8, Windows 8.1, Windows 10, Windows Server 2012.
This can also be done if the keyboard is missing or not working. A computer mouse will become your assistant. Modern UEFI BIOS supports the use of such a manipulator. The earlier version of Legasy BIOS does not provide this feature. Only the keyboard is available to the user.
So, the conditions for using the mouse to enter and work in the BIOS:
Using UEFI BIOS mode on your computer;
- Windows OS on the computer must be running and in working condition;
- use of a working manipulator (computer mouse).
IMPORTANT! This makes it possible to enter the BIOS directly from Windows OS at any time while working on the PC. This happens, for example, in a situation where the user simply fails to press a certain key combination when booting the computer.
Sign-in features for Windows 8.1 (Windows 8)
From a running Windows 8.1 or Windows 8 operating system, you can easily enter the UEFI BIOS even without a keyboard. To do this, follow these steps with a computer mouse.
There should be a “Desktop” on the monitor in front of you. Move the mouse cursor to its right edge - at the top or bottom of the screen.
Select the “Settings” icon in the sidebar, click and look for the “Change computer settings” section.
Here we find the “Update and Recovery” section, where we click on the “Recovery” line.
You should pay attention to such a parameter as “Special download options”. Here you should select the line “Reboot now” and click on it. This is hello to rebooting your computer.
After this, in the “Select Action” window, select the “Diagnostics” line and run it. A new window will appear - “Advanced Settings”.
After clicking on this button, in the next window you need to select the “UEFI Firmware Settings” section and click on the “Reboot” button in it. This will change the necessary parameters.
IMPORTANT! The computer will restart again. After this, the BIOS UEFI will open directly, where you can make all the settings the user needs.
Sign-in features for Windows 10
In this version of the operating system, you can also enter the BIOS without using the keyboard while Windows 10 is running. To make this possible, you need to go through several stages of reconfiguration.
On a running Windows 10 operating system, go to the Start menu and find the Settings section.
Run the “Update and Security” line, which will open the “Recovery” section.
Attention should be paid to the line “Special download options”. You need to find the “Restart now” button among them and click on it. The computer will restart.
When it boots up again, you need to find the “Troubleshooting” button in the “Select Action” window. Activate this command.
The “Diagnostics” window will appear, where you need to find and activate the “Advanced Settings” button. In the window that opens, select the section “UEFI Firmware Settings”.
IMPORTANT! When the device is fully booted, the UEFI BIOS window will open, where the user should perform the necessary reconfiguration. Its features depend on the specific needs of the user. It can, for example, restore previously disabled USB keyboard support, and also set up a specific queue for booting from disks.
As you can see, entering the BIOS is possible under certain circumstances even on a running Windows operating system. And you don't need a working keyboard for this. The main thing is that the technical conditions that ensure the possibility and success of such a procedure are met.
How to enter BIOS without using the keyboard.
To enter the BIOS, you use the keyboard keys, and the entry itself takes place before the Windows operating system boots. In some situations, access to the BIOS without a keyboard is necessary.
The BIOS is included to configure or change some computer parameters, to select the boot priority from a specific disk, bootable flash drive or CD/DVD drive, for example, this is needed to install Windows from bootable media.
BIOS (basic input/output system) - a basic input/output system consisting of a set of chips on the motherboard with system software. BIOS is necessary to check and configure the computer hardware before starting the system; BIOS is used to load the Windows operating system.
Usually, immediately after starting the computer, when the motherboard manufacturer or laptop manufacturer's splash screen appears on the screen, you need to press a specific key, or several keyboard keys, to enter the BIOS. Which keys are used to start displaying the BIOS on the screen depends on the BIOS developer and the motherboard manufacturer, and on devices: desktop PCs or laptops, a variety of keyboard keys are used.
In some cases, the user is not able to use the keyboard to enter the BIOS on the PC. This is influenced by several circumstances:
- keyboard malfunction;
- damage to connectors or wires at the keyboard or on the system unit;
- In the BIOS settings, the USB keyboard is disabled or not supported.
If the keyboard itself is faulty, it must be tested on another computer and then replaced with a working keyboard. The same applies to malfunctions of the power cable or connection points to the computer.
If your computer does not support a USB keyboard, or support for such a keyboard is disabled in the BIOS settings, use a keyboard with a PS/2 connector, or install an adapter from a USB keyboard to the PS/2 port on the computer.
In this article we will look at how to enter the BIOS on Windows, in a running operating system, and not when loading Windows, as usual, you enter the BIOS to perform certain actions. This method works in UEFI BIOS, in the operating systems Windows 10, Windows 8.1, Windows 8, Windows Server 2012.
If, for some reason, the keyboard does not work, and the user is tormented by the question of how to enter the BIOS, a manipulator will help him: a computer mouse. In modern PCs, the UEFI BIOS supports the use of a mouse, unlike the regular BIOS (Legacy BIOS), in which you can only work using the keyboard keys.
To do this, the following conditions must be met:
- the computer uses UEFI BIOS mode;
- The Windows operating system must be running on the PC;
- A working computer mouse is connected to the computer.
In this article you will find instructions for the operating systems Windows 10 and Windows 8.1 (Windows 8).
Using the method described in the article, you can also enter the BIOS with the keyboard running, directly from the Windows operating system. For example, if when starting the computer, the user did not have time to press the required key to enter the BIOS.
How to enter BIOS without a keyboard in Windows 10
