How to resume system operation without a keyboard. Why does the keyboard not work when Windows starts? Setting the correct parameters

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 setup. 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.

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 quite working (according to his words) and when he pulled it out, the keyboard started working in normal mode. I don’t know how this is connected, but if something happens, you can try this method.

Well, I’ll finish 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!

Sometimes the computer crashes, which can cause problems with the keyboard displaying in the system. If it does not start in the BIOS, then this greatly complicates the user's interaction with the computer, since most versions of the basic input and output system only support the keyboard. In this article, we will look at how to enable the keyboard in the BIOS if it refuses to function there despite its physical functionality.

If the keyboard works normally in the operating system, but before it starts loading it does not work, then there may be several explanations for this:

• Support for USB ports is disabled in the BIOS. This reason is only relevant for USB keyboards;
• A software glitch has occurred;
• Incorrect BIOS settings were set.

Method 1: enable support in BIOS

If you just bought a keyboard that connects to your computer via USB, then there is a chance that your BIOS simply does not support USB connection or for some reason it is disabled in the settings. In the latter case, everything can be fixed quite quickly - find and connect some old keyboard so that you can interact with the BIOS interface.

Follow these step-by-step instructions:

If your BIOS does not contain items regarding USB keyboard support, then you need to update it or buy a special adapter to connect a USB keyboard to the PS/2 connector. However, a keyboard connected in this way is unlikely to work correctly.

Method 2: Reset BIOS Settings

This method is more relevant for those whose keyboard previously worked normally in both BIOS and Windows. In the case of resetting the BIOS settings to factory settings, you can return the keyboard to functionality, but at the same time, important settings that you made will also be reset and will have to be restored manually.

To reset, you need to disassemble the computer case and temporarily remove a special battery or jumper the contacts.

The above methods for solving the problem can only be useful if the keyboard/port does not have any physical damage. If any were found, then some of these elements need repair/replacement.

Included with the computer. Almost all data and actions are entered using the keyboard, and any mouse movement will provide a key combination. Therefore, a keyboard failure after booting the system threatens, at a minimum, with difficulties typing text information...

Windows is loaded, but the keyboard does not respond to your commands. There are only two reasons, hardware and software. Moreover, the first one occurs much more often, and is solved by simply replacing faulty equipment.

Checking the keyboard

To check the hardware, that is, the keyboard itself, you only need a known working input device. First, do a visual inspection of your computer's connectors (USB or PS/2), as well as the cable and connector of your keyboard.

In the case of a USB connection, the connector suffers, where the contacts can come loose and cause the computer to short out. With a PS/2 connector, on the contrary, more often the defect occurs in the plug in which the contact legs are bent or broken off. If the inspection shows that there are no deviations, then we try to connect the prepared keyboard.

Be sure to completely turn off the computer and then disconnect the existing keyboard to replace it. It is better if the second keyboard is of the same connection type, this will help localize the problem. If the device behaves similarly after loading Windows, then you should look for the reason in the software.

Checking the driver

Software means the required set of drivers, which should determine your hardware. If the driver is installed incorrectly or is incompatible with the operating system, you should reinstall the keyboard or install a new version of the driver.

In Windows OS, we go to “Device Manager”, where we find the keyboard (depending on the connection type). Right-click and select “Delete” from the context. Next, it is enough to restart the computer so that the system finds and installs the equipment (or use the Connect New Equipment Wizard).

In case you need to update the driver, go to the Internet. On the manufacturer’s official website we find the downloads section, where we find the name of your device model. Download the installation file for your operating system, and then double-click to install.

Non-standard reasons

If all of the above did not help in your situation, then you should check your BIOS settings. One of the sections is responsible for the functioning of input devices. Usually, this option is possible with manual intervention, and if this was not the case, then you can limit your actions.

A viral infection is also possible. In this case, both input devices suffer, both the keyboard and the mouse ()). Usually, the action of such “pests” prevents work in normal mode, when “safe mode” remains at your disposal. Using this type of Windows boot, we launch
