Hello everyone, dear friends. Quite recently, a strange situation occurred at my work, as it seemed to me. The keyboard just stopped working. Or rather, it didn’t completely stop. As it turned out, the keyboard only works in the BIOS, and upon further boot it simply stops responding to any presses.
And then an unpleasant situation occurred, or rather a failure. After the reboot, I had to select the boot mode, but I could not do anything, since none of the keys responded. First of all, I thought that it was the keyboard’s fault, after which I replaced it with a new one, but it turned out, but after I I installed another device, the situation did not change.
In general, I won’t bore you. Most likely you used a USB keyboard, since no one had such problems with PS/2. The thing is that your BIOS disables USB keyboard support when Windows boots.
"How so? After all, everything worked before,” you say. Yes, indeed, everything could work for you, and you could not notice anything, since when you load the operating system, it will automatically activate this support. But once a crash happens and you need to do something during the loading screen, then unfortunately there is nothing you can do.
What to do then? I want to say right away that the first thing you need to do is check the simplest thing that can only come to your mind, because sometimes the problem can really be somewhere on the surface. Therefore, first check whether the keyboard cable is connected to the computer, try moving it to another USB port, and if possible, connect another keyboard.
If none of this helps, then most likely it's a configuration issue. You need to login BIOS, namely at the very beginning of booting your computer, press the function key responsible for entering. Most often this is the key DEL, but in different cases this may be F1, And F2.
As a result, when you get into the BIOS itself, depending on the version, you will need to find an item related to USB keyboard support. It may be called "USB Keyboard Support" or "Legacy USB Support". If you see that the “Disabled” mode is next to these items, then support is disabled and you need to activate the “Enabled” mode.
After that, save all the settings, reboot and voila.
As a rule, this setting is the solution to this problem. Although I heard that this solution did not help someone, and he decided to try to look for the problem in the components. It turned out that one stick of RAM was not entirely working (in his words) and when he pulled it out, the keyboard started working normally. I don’t know how this is connected, but if something happens, you can try this method.
Well, I’ll end here. I hope you liked my article. And if you still haven’t subscribed to my blog updates, be sure to do so now so as not to miss the most interesting things. Well, I'm waiting for you again on my blog. Good luck to you. Bye bye!
Question from a user
Hello.
Tell me about one problem: I just can’t get into the BIOS, I’ve 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 PC specification). What can be done?
Hello.
It is difficult to name a definite reason (by the way, you indicated the motherboard model 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 go into the BIOS to install a new OS, then this can be done differently (see points 4, 5 below) ...
What to do if the computer does not enter BIOS/UEFI
Key and time it was pressed
And so, the first thing you should start to deal 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 boards from GIGABYTE as well). Slightly less common are the F2, ESC, F10, F12 keys. See the instructions below for buttons for different manufacturers.

Also important one moment: BIOS/UEFI loading can happen so quickly that you may simply not have time to press the desired key. Therefore, try another option: when the PC/laptop is still turned off, hold down the enter key (ESC, for example), and then turn on the device (do not press the key before entering the BIOS!).
Press and hold 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 Windows 8/10 installed, then you can enter the BIOS through the OS interface.
First you need to open the section "Recoveries" in the system parameters. 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 automatically open...

Keyboard model and port used
Wireless keyboards have become very popular now. Everything would be fine, but a number of models simply do not work until Windows boots (the same can be said about some USB keyboards connected via various adapters...).
The advice here is simple: 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 wall of the system unit (if connected to USB 3.0, try USB 2.0 ports).
Resetting BIOS Settings
In some cases, default helps fix the problem. To do this, you can use two methods:
By the way! After such a procedure (even if you still can't get into the BIOS) Most likely its settings have been reset. And this can, for example, allow you to run Windows installation from a bootable USB flash drive/DVD (because by default, in many BIOS versions, the first boot device is a CD/flash drive, and then the hard drive).
❺
Disabling the hard drive
In some cases, due to a failed hard drive, its initialization is delayed (sometimes it even leads to the PC freezing). Of course, this point may also be the cause of the problem in question...
What can be done: try disconnecting all drives from SATA, USB, M2 ports of the PC (flash drives, hard drives, solid-state drives, etc.). Ideally, leave one keyboard and monitor, then reboot the device and try to enter the BIOS.
By the way! If you need to go into the BIOS to install the OS, you can try formatting the hard drive on another PC and then connecting it to the current one. Thus, Windows will not start from it and the PC will automatically try to boot from the connected installation flash drive (CD). At least this is 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: the new version does not always work more stable than the current one).
Modern devices allow you to run BIOS/UEFI updates directly from Windows. The entire update usually comes down to downloading and running the 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, this method is relevant for those who already have Windows on disk. More detailed instructions below.

Our website has already repeatedly talked about ways to enter the BIOS and, as a rule, they always use the keyboard, on which a special hot key must be pressed. Below we will look at all the available methods that allow you to enter the BIOS in cases where you cannot use the keyboard.
As a rule, users need to enter the BIOS without a keyboard in two cases: either the keyboard itself or the USB ports were broken, which is why it is impossible to enter the BIOS in the usual way, or the operation of the USB ports was accidentally deactivated in the BIOS settings .
Option 1 (not for everyone): enter BIOS using a special button
Some laptops (usually from Lenovo) are equipped with a separate button on the case, which allows you to immediately go to the BIOS without first rebooting (turning on the system) and pressing a hot key on the keyboard.
The disadvantage of this method is that not everyone has such a button, and in very rare cases it can be seen on desktop computers. Perhaps this is the only way that can enter the BIOS without actually using the keyboard.
Option 2: device repair
If you cannot use the keyboard to enter the BIOS because it is broken, you need to use another keyboard (no surprise). If the ports on the computer have stopped working, this problem must be corrected at a service center, where a specialist will be able to conduct diagnostics and identify the cause of the problem, and therefore fix it in a timely manner.
Option 3: Reset BIOS Settings
Many users cannot enter the BIOS due to the fact that the parameter responsible for the operation of connected devices to USB ports was previously disabled in this settings menu. Again, without a keyboard, there's no way you can get into the BIOS, but you do have the option to perform a factory reset.
As a rule, to do this you need to look under the system unit case and find a jumper on the motherboard "Clear CMOS", move it to another position for 10 seconds, and then return it to its previous position.
After completing these steps, you can turn on the computer - the BIOS settings will be reset, which means the keyboard will work safely.
Option 4: use a PS/2 keyboard or adapter
Some particularly older BIOS versions may not support a USB keyboard, in which case you will not be able to access settings using it. You can solve the problem if you connect a keyboard with a PS/2 connector or buy an adapter from USB to PS/2 to the existing one.
Unfortunately, you won’t be able to directly enter the BIOS without a keyboard; in any case, you will need to use it. Choose the appropriate option based on the cause of the problem that prevents you from entering the BIOS in your case. If you have any questions, ask them in the comments.
BIOS is a collection of microprograms that regulate the operation of all devices and loading of the operating system. Essentially this is the most important component of any processor. The BIOS is located on the motherboard because the motherboard is responsible for managing all the devices in the computer.
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 brand) there is a special button on the keyboard. It allows you to quickly navigate to settings without requiring a reboot.
However, not all laptops have this button, and in personal computers it is very rare. 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 reset the BIOS settings, you need to turn off the computer and press 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, it is necessary to perform a forced wipe. This is done by removing the battery.
Algorithm for performing forced cleaning
- De-energize the computer. To ensure that the capacitors are completely discharged, you need to press the power button several times.
- After this, we find in the block (or inside the laptop case) a battery that 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 Windows 8 and Windows 10 operating systems, there is another way to enter the BIOS settings - using the mouse.
To do this, you need to complete the following steps.
- In Settings, select Update & 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 launch the BIOS without using the keyboard.
Alternative method of entering BIOS settings
In addition to the above methods, There are also methods that will help you return the BIOS to factory settings without using the keyboard.
Jumper manipulation
To perform a factory reset this way, you need to 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 some time (from 10 to 20 seconds).
- After this time, return it to its original position.
When if such a trigger was not found, this means that you have two contacts. Therefore, to perform this manipulation use a conductive tool(preferably with a screwdriver). You need to press the contacts for approximately 20 seconds. After that, just turn on the computer and make sure that the keyboard works.
Sometimes it happens that PC users are faced with the following situation: when they turn on the computer, the keyboard does not function. Everything seems to be connected, but the buttons do not respond to pressing. When the device is rebooted, the keyboard works, but only in the BIOS. As soon as the download starts, it turns off again and shows no signs of life. In addition, a warning may appear on the screen asking you to select safe mode, and simply pressing the F8 button does not produce any results.
The first thing that comes to mind is to replace the keyboard. However, there is no need to rush. If the problem is not in the part itself, then the new one will react in exactly the same way when loaded, or rather, not at all. So check other potential causes first.
The problem may not be the keyboard at all, but rather a tricky Windows setting. As a rule, most users today use USB devices; others are no longer produced. In this case, the problem is related to the BIOS disabling support for your keyboard when the system boots.
What went wrong and how to fix the situation?
Such troubles arise precisely because of an OS failure. When you turn on the computer, the system stops responding to the device that previously connected automatically, and as a result, the keyboard does not work. In other words, the operating system simply “does not see” the device.
But don't despair. The recipe for correcting the situation is much simpler than it might seem at first glance. You need to make sure that the keyboard is working and connected. Otherwise, everything that will be discussed further will not work. In this case, you will still have to look for a replacement. First, try reconnecting the keyboard to a different port. If it doesn't help, move on.
The next step is to enter the BIOS. To do this, hold down the Del, F1 or F2 key (on different devices, the menu is entered using different buttons, most often it is Del). Hold down the desired key for a few seconds.
On the blue screen you need to find the menu item associated with our keyboard. It is usually called USB Keyboard Support, and on some models may be called Legacy USB Support. In this case, there will be a note next to the item indicating that the option is disabled. To activate the keyboard in the BIOS, just switch to Enabled mode. Don't forget to save your settings. To do this, press the F10 key and confirm your changes. Now restart your computer and check the result. The keyboard now works normally.
