Hello everyone, dear friends. Recently, a situation at work became surprising to me. The keyboard just stopped working. More precisely, it didn’t stop completely. As it turns out, the keyboard only works in the BIOS, and with further pressure it simply stops responding to any pressure.

And then the situation became unacceptable, or more precisely, it became a disaster. After re-enchanting, I needed to select the enchanting mode, otherwise I could not get anything done, because neither of the keys responded. Having installed another device, the situation did not change.

Zagalom, I’m not bothering you. They blamed the USB keyboard for everything, since no one had such problems with PS/2. On the right is that your BIOS has USB keyboard support enabled when Windows is running.

“How can it be so? Everything worked before,” you say. So, of course, everything could work for you, and you could not mark anything, as long as the operating system is activated, it automatically activates this support. There is a death And you need to do all sorts of things while watching the screen, then, unfortunately, you won’t be able to do anything.

How to do it then? I would like to say immediately that we first need to reconsider the simplest thing that may come to your mind, and sometimes the problem of truth may be here on the surface. Then, first turn over the keyboard cable connected to the computer, try moving it to another USB port, if possible, then connect another keyboard.

If nothing helped, then, after everything, on the right in the adjustment. You need to go to BIOS, and press a function key on the front of your computer, which indicates the entrance. Most often this is the key DEL, but in different cases it may be F1, і F2.

As a result, if you go into the BIOS itself, you will, depending on the version, need to know the item related to the USB keyboard support. It may be called "USB Keyboard Support" or "Legacy USB Support". If you see that opposite these points there is a “Disabled” mode, then the support is disabled and you need to activate the “Enabled” mode.

After that, we save all the adjustments, restart and voila.

As a rule, correcting the problem itself is the most important thing. Although I feel that this solution did not help anyone, I decided to try to find a problem in the components. It turned out that one stick of RAM was not completely working (in my words) and when it was removed, the keyboard requested in normal mode. I don’t know how this is related, but maybe you can try this method.

Well, I’ll leave it at that. I am confident that you were honored with my article. And if you haven’t already subscribed to the latest blog, you must sign up now so you don’t miss anything that’s new. Well, I’m counting on you on my behalf. Good luck to you. Boo!

Fortunately, the keyboard is now such a popular device that you can buy it from any supermarket, not to mention specialized stores. Regardless of the simplicity of this gadget, it can cause problems and malfunctions. One of the most common problems sounds something like this: “The keyboard has stopped working.” The axis just stopped and that’s it. Today I will tell you about those who can get help and how to deal with problems. It is also necessary to add that in this case we are talking about a computer keyboard, but I will talk about a laptop keyboard next time, since there is an even greater difference between them.

Causes of problems and verses

Why are you printing the varto? We can’t panic right now. Well, that’s true, because in 90% of people who have seizures, your problem is very easy to solve.

• If you have a pet that loves to climb, I recommend that you take a look at the back wall of the system unit. It is possible that the cat, while passing through, caught the keyboard plug and it simply fell out of the socket.

• The next possible option is a glitch that has occurred in the operating system. For such episodes there are two major problems. First, remove the plug for a few seconds and insert it back, or else, restart the computer if the first option did not work. After restarting the PC, devices begin to work in 90% of cases.

• If you are using a PS/2 keyboard, take a good look at the connector itself. On the right, the legs could have been bent, which must be corrected, otherwise we cannot proceed. Why would you use tweezers (ideally) or a needle?

• Most modern keyboards (such as these) connect to a PC based on a regular USB system. It is recommended to change the USB port and check the functionality of the device. Ideally, it would be best to check it on another PC or laptop.

• Theoretically, it is possible that the keyboard has given up life for a long time, in other words, it has become obsolete. However, in practice, this is rarely the case, and often only one or a few buttons work well. It’s easy to verify - connect the device to another computer or laptop.

• One of the most pressing problems is related to the loss of numbers - users say that the right part of the gadget does not work, deleting the numbers. In fact, it is connected to power using the Num Lock button, which is located above the numbers. This has been divided up so that the numbers are not too crowded.

• Often on the keyboard in the places where the buttons are located, there is a rubber band located in the middle of the case. Sometimes various items and other small objects are used on it. To get rid of it, the keyboard must be taken out and cleaned. Before speaking, great cries can be pressed under one key and the onslaught will stop. In this case, it is enough to remove only one key, so, fortunately, it is very easy to hesitate.

• If you have a keyboard with no additional buttons, you may need to install additional drivers. Without them, the keyboard may not work, except for the other buttons. It is necessary to install drivers for the device, which can be found on the official website of the manufacturer.

• Before we talk about drivers. In some cases, the problem is not with the keyboard, but with the driver that drives its operation. Pozhlovo, yogo bulo poshkodzheno. This problem can be solved in two ways: either by updating the drivers to the latest version, or several days before the keyboard has been working.

• If you just got your computer and haven’t tried it yet, try going into Bios - the keyboard support may be disabled. In the BIOS menu, you need to find the item called USB Keyboard Support and change it from Disabled to Enabled.

• If you are using a wireless device (keyboard) that uses batteries, be sure to charge it. Perhaps it just ran out of charge, and the other one stopped working.

• And computer users often complain about the fact that the keyboard does not work in games or programs. Fortunately, in most cases it’s easy to deal with this problem. On the right is that after singing the keruvannya is programmed for song keys, which you can change at your discretion. For this purpose it is necessary to go to the setup room. I am in complete peace.

Finally, I’ll remind you once again that in most cases you can solve the problem with the keyboard on your own. Well, if she still decided to work, she would have to spend money on buying a new one, because the repair of this building would be incredibly expensive.

The removal of any of the elements of the computer’s periphery means the rotation or external application of the entire set. If the keyboard does not work, then working with the computer becomes cumbersome, as long as it is not possible to enter data. The use of the on-screen keyboard does not pose a problem, as long as its functionality does not provide full functionality to the work. In this case, you need to apply immediately and run to the store for a new device. Most often, the problem can be solved locally, without going to drastic methods.

Why the keyboard may not work - look for the cause of the problem

As long as the lights on the keyboard connection are on, everything is not so bad. It’s more complicated because the device doesn’t show any signs of life. The first thing that needs to be done is to identify the possible causes of the malfunction. For this purpose, it is important to carefully inspect the device, the connecting wire, check the connections and proceed with further actions. Then you need to connect the problematic keyboard to another computer. Also, don’t forget to connect a properly functioning keyboard to your computer and reconnect if there are any problems with the software, using the connection ports. To put it simply, you need to get out of the way - the keyboard is not working, and there are problems in the computer.

Physical failure

Most of these problems arise from very noticeable circuits - broken wires, mechanical damage, etc. Based on the nature of the problem detected, you can draw approximate conclusions about the device’s function, although damage to the case does not necessarily mean that the keyboard is out of order. The situation is complicated, if the keyboard does not work, there are no visible signs of damage. If you connect to another computer, the problem goes away if you check the connection wire. It often breaks at the entrance to the housing of the device or (rarely) at the correct plug.

Let's drink some tea with some tea, and use the keyboard to set up a lot of devices.

PZ has problems

If, when connected to another computer, the keyboard operates in normal mode, then the software is responsible for everything. You may need to install or update the device driver. First of all, you need to check the keyboard settings in Device Manager. In Windows 7, for this purpose, right-click on the computer in the Start menu. In Windows 10, you can open it by typing “device manager” at the end of the search panel. Since in the “keyboard” section there is a name for the problematic device without additional icons (namely, the familiar trikutnik), it means that the system will continue to work and not encounter any problems.

Other reasons

Those who like to snack while working on the computer often spill carnage on it. The sound of drinking tea with tea, with which and other drinks I instructed from the keyboard, brought out many devices out of harmony, but it may not be possible to get rid of them soon. Cause traces of spilled liquid to appear on the surface, as if they were immediately erased. Signs of such a malfunction include the absence of normal reaction of the button action, sticking of adjacent buttons, and erratic commands from the keyboard. Often she begins to endlessly destroy one writer or kill a team.

The most common problem with dartless guns is batteries. When its capacity begins to drop noticeably, the device becomes unstable and at some point begins to kick in.

What the keyboard doesn't do is a major problem in a variety of ways

The problems that arose with the keyboard were a big deal. The order of actions depends on the specifics of the faults and is selected according to their scale. Let's take a look at a possible algorithm for this or that situation.

Replacement or replacement of the keyboard, connecting cable

Mechanical failures of the device can be repaired with only minor damage. A fracture in the body or similar great failures do not deprive one of the chances of success. The most distant actions can be to cleanse the device from the source that has penetrated into the middle (sweet tea, kava) or replace the desired dart.

To clean, you need to remove the device. The keyboard is connected to the computer. Carefully remove all the buttons, remove the humic transfers, wipe off the dried liquid with a soft foam and alcohol. After cleaning is completed, the keyboard is collected in the return sequence. Particular attention is paid to the installation of large buttons, which are not simply inserted at the output socket, but are fixed with straight metal.

Video: Repairing the connecting cable

Since there are no ready-made soldered plugs at hand, it is easiest to add a new keyboard and not waste an hour searching for the required parts or elements.

Repairs can only be made based on the knowledge of the design and the knowledge of the structure. All actions based on temptation will not ensure positive results. If the essence of the breakdown that occurred is unclear, then the correct thing to do is simply replace the keyboard with a new one, without fail.

Check the drivers for the main peripheral devices included with Windows. Tim is not less, new elements, bezdrotov or have additional functions, require the use of high-quality software. The necessary drivers are supplied immediately from the devices on CDs. Whenever you need it, you can download the security program from the Internet and install it on your computer. There is a simpler way - open the device manager, find the "Keyboard" item, right-click on it and select "update drivers" from the list. The system itself will find out and install the required software.

Check the drivers for the main peripheral devices included with the Windows system

This change may be necessary when replacing an old keyboard with a PC/2 connector with a larger one with a USB connector, or when connecting the device to a laptop. If you have configured the BIOS, you need to find the USB Controller tab and set the value to Enabled. Then you need to find the USB Keyboard Support tab (it can also be called USB Legacy Support) and also set Enabled. If you plan to use the keyboard in DOS, you will need to enable the following values ​​in the USB Keyboard Support Via tab, although this is not available for all BIOS versions.

This change may be necessary when replacing an old keyboard with a PC/2 connector with a larger one with a USB connector

Reporters indicate that problems with USB keyboards occur quite often. To avoid this, you can use a PC/2-USB adapter. And here most problems arise automatically, but the usefulness of the adapter must be verified.

Adjusting the keyboard itself

The keyboard settings can be configured in the Windows panel: menu "Start" - "Keyboard Panel" - "Keyboard" - "Power: Keyboard". You can change:

1. The speed (frequency) will repeat the creation of the symbol when the key is pressed.
2. I will repeat the trimming before the cob. The parameter indicates the hour required for the next symbol to appear when pressing a key.
3. The frequency changes with the cursor on the screen.
4. Please enter information below for further information.
5. Buttons for switching layouts.
6. Dodatkova support mov

The keyboard settings can be configured in the Windows panel: menu “Start” - “Keyboard Panel” - “Keyboard” - “Power: Keyboard”

The keyboard adjustments should not be changed, as long as the basic parameters are set as normal. Due to any actions of the user or system failures, the adjustment may change, so if any problems appear, it is recommended to install them in the necessary order.

One of the reasons for your device being detected could be a virus that was transmitted to your computer via the Internet or from an infected external device.

One of the reasons for your device being detected could be a virus that was transmitted to your computer via the Internet or from an infected external device. If the sign of an unstable robot or virus appears again, you must run a new virus scan of your computer. You can check the official anti-virus program installed on your computer by clicking on the program icon in the taskbar and clicking the “Check” button; most anti-virus programs can be found on the main page and good visible. You can also download and run the Dr.Web CureIt! or Kaspersky Virus Removal Tool. These are cost-free programs that effectively detect threats that may be missed by installed anti-virus software.

After the scan is completed and threats have been identified, the computer will be re-enabled

After the verification is completed and threats have been identified, the computer is re-secured and the functionality of the device is checked.

Checking the usefulness of the keyboard itself

It is necessary to note that the keyboard is working. For this purpose, connect to another computer and check the validity. If the problem goes away, the cause of the malfunction lies in the device itself. If it starts to work in normal mode, then the problem is either hardware or software in the computer. This verification option requires you to choose one of the first ones, although you will always have another computer at hand. The ability to localize a problem allows you to speed up its resolution.

otherwise

The color of the socket corresponds to the color of the plug; for a keyboard it is blue

Problems with the keyboard may arise from other reasons. For example, if you connect a PS/2 device to a laptop, you can remove the motherboard. For many computer users, it is very easy to do this, especially those who use a USB keyboard. This can happen even with a slow computer, or with an older PS/2; this option is unacceptable. You need to turn on the computer normally and then unplug the keyboard and connect another one. In addition, it is not uncommon to connect the PS/2 plug to the socket under the mouse without instructions.

A keyboard that has stopped working can, in most cases, be renewed or used again. Basic nutrition will benefit from such an update, as far as it is durable and reliable. The price of a new device is not so high that you would spend an hour on the keyboard, which I found with incredible results. Therefore, having realized that the reason seems to be not in the hardware part of the computer or software, but in the keyboard itself, you will find that it is better to repair it, or it is easier to buy a new one. Independent actions will require you to spend time through marriage, or if you spend nothing, trying nothing will add up. You can only get your keyboard repaired because it’s too expensive, and paying for a replacement is unaffordable compared to the price of a new device. In the end, the most reliable solution would be to add a new keyboard.

Instructions

The main reasons for such a malfunction lie in hardware or software failure. It’s easy to check the hardware version – reverse the plug on the keyboard and the connection socket. Since everything is visual, replace the keyboard with the right one and reinstall the computer. If you are no longer able to operate this device quickly, check the version of the software problem.

To begin with, try restarting the car. It is possible that the operating system localizes and eliminates the software failure. Try reinserting the keyboard. To do this, in the “System Power” window, in the “System” item, “Control Panels”, find the “Power” tab. Click on the “Device Manager” button. In the “Device Manager” window, see the “Keyboard” item and delete it, close the “Device Manager”. Then leave the “Installation” item and run the “Installation Wizard”. Click the "Next" button and wait until the installation program displays the keyboard. When the OS keyboard is detected and functioning, the Num Lock light indicator will light up. When the program displays a notification that the installation of new devices has been completed and confirms re-installation, press the “No” button while the keyboard is still functioning. Also click the “Done” button in the “Hardware Installation Wizard” window and exit the “System Power” menu.

One possible problem could be that the operating system does not detect the required driver. To reinstall the driver, go to the website of your keyboard manufacturer, select the required model, download the archives and unzip it. As a rule, such drivers are provided with their own installation program, and then you just run the file. If this is the case, you will have to launch the “Device Manager”, select the “Update driver” command and enter the manual search mode to the directory in which the unpacked driver is located. The computer must be restarted after installation.

Most often, a non-functional keyboard is a legacy of a virus program that is installed on your machine. A characteristic feature of this is that the robot has a mouse, as well as a touchpad. Check your system for additional anti-virus software. It’s better not to rely on costless utilities that guarantee the success of the meeting and the cleanliness of your computer. Vikorize any antivirus that you have proven yourself. The chances of success with such security are greater.

The real reason for the invisible keyboard may also be the lack of BIOS connection. This kind of failure is especially common on machines with a built-in keyboard. Vibrating the situation will be easy. Whenever you need to turn on your computer, turn down the BIOS. Find a tab with a list of devices entered and displayed. Select USB Controller and click Enabled. Disable this mode for USB Keyboard Setup. Exit the BIOS to confirm saving the new settings. If nothing from the overinsurance helped you, go to the service center.
