All letters are printed. The keyboard does not print the letters you press. Possible driver problems

Probably, each of us has encountered a similar situation: you turned on the computer, are trying to enter text on the keyboard or switch from one window to another, but the keys do not respond to pressing, and the device itself does not show any signs of life. What causes this behavior of the device? Why doesn't the keyboard on my computer or laptop work? And how to fix it? Let's consider what the reasons may be.

This is actually extremely awkward compared to others as it requires an excess of finger movement. Another standard is Dvorak. In addition, there are two other standards created for those who only need to enter one hand. Now check out some keyboards that might make you spend hours admiring the store window.

They usually have additional features over regular keyboards. You'll notice in the photo that there's also a mouse on the back of the touchpad-style peripheral. Anyone looking for practicality will want to have it. The keyboard below looks strange, but it makes the eyes of many gamers and graphics players sparkle because their keys are fully customizable not only in the function of the keys, but also in the position they occupy. You can literally put the keys wherever you want and assign them any function.

Mechanical damage

The simplest explanation is mechanical damage to the keyboard. Perhaps you recently spilled coffee or sweet tea on it, accidentally dropped it, pulled the wire, etc., and then conveniently forgot about it. In this case, all you have to do is disassemble the device and try to fix it yourself, or contact a service center. The second option is preferable, especially when it comes to a laptop keyboard. If you cannot bring the keyboard back to life, you will have to purchase a new input device.

Do your friends watch what you type and call you a “photographer”? It has both wired and wireless options and is available in Brazil. But it doesn't stop there, as the keys can be customized to display symbols for tools, commands, programs, or even images you've taken. Maybe in Portuguese we could have a keyboard that would better suit our needs and cause less pain in the hands of those who use the equipment for long hours on end?

Why hasn't a single keyboard manufacturer in Brazil proposed changing the standard to make life easier for users until today? With such great success in software interfaces to make it easier for the user because the keyboard is stopped in time?

Lost contact

Sometimes keyboard problems are caused by the device not being properly connected to the computer. Check whether the plug fits tightly into the socket on the system unit and whether the fragile parts of the connector are bent. If necessary, carefully straighten them with tweezers and try connecting the keyboard again.

If you use a wireless keyboard, it's worth checking to see if its battery is dead. Very often the problem disappears without a trace as soon as the power source is replaced.

Feel free to give your answers and explain your theories using the feedback system. If your keyboard is no longer working, there are a few things you can check to resolve the issue. Depending on your situation, you can try one of the following options: First, you should identify two important factors in this troubleshooting solution.

Your keyboard no longer works

The problem occurred while typing, or you noticed it immediately after starting your computer. Apart from an extreme situation such as spilling water on the keyboard, the answer to this question is important in identifying the problem. If you notice that your keyboard has stopped working after downloading or, check your connection to your keyboard and make sure it is locked properly. You can reboot again.

No corresponding driver

Why does the keyboard on the computer not work if the contact is not broken and the device itself is not damaged?

Perhaps the system simply cannot find the driver for the device. In this case, you need to update your computer software.

You can do this manually by visiting the website of your keyboard manufacturer.

What keyboard are you using?

Disable desktop computer and check if it doesn't work. Also check the batteries, it may be time to change them. Wireless receivers have a signal scan button, press the button to transmit the signal and the light should start flashing. Once this happens, find the key on your keyboard to receive the signal sent by the receiver and flow with each other.

In some ways, these keyboards are more reliable because there are no drivers to install from the operating system. If it stops working while using the operating system, in most cases the problem is not caused by the keyboard. Check if your mouse is moving slowly? Do the same for each application that is not responding. You can also try this for any type of keyboard.

Be patient and wait until the operating system finishes.
On the Application tab, select all and click End Task.
A confirmation window will appear asking you to stop it.
Click "End Task" again and wait for it to complete.

To determine the status of your keyboard, you can follow the last step.

Manual driver update

go to the official website of the manufacturer;
find the appropriate section, select your device model;
download the archive and unpack it. Sometimes the driver has its own automatic installer, in which case you will just need to click “Run file”;
if there is no automatic program, launch “Device Manager”;
select “Update drivers”, in the dialog that opens, select manual search, enter the path to the folder in which you unpacked the archive;
After installation, reboot the computer.

There is another way to update drivers. It is often recommended on thematic forums when a participant does not know why the keyboard does not work on a Windows 7 computer or other OS. You won't have to look for manufacturers' websites, but you will need to install additional programs to update drivers. For example, Driver Genius Professional or Driver Checker. These utilities are paid, but if you wish, you can find a replacement for them among free software (DriverMax Free, etc.).

If your keyboard no longer works, but you have a good second known keyboard with the same connection type, replace the correct keyboard with the incorrect one and see if it works. You can also try connecting the incorrect keyboard to another computer and determine if the keyboard is broken.

Troubleshooting Wireless Keyboards

If some keys on your keyboard work but not all, follow the steps below as appropriate for your situation. The eject button mechanism starts after a short delay to avoid occasional use. Press and hold until the eject icon appears on the screen.

Viruses attacked

Sometimes input devices are blocked by malware. If you don’t know why the keyboard on your laptop or computer, and along with it the touchpad and mouse, don’t work, then the problem is most likely due to a virus infection of the system. What to do in this case?

and how can I fix it? Forgot your computer password? Don't worry - in our article you will find information on how to restore it.

Check your system with an antivirus as soon as possible. If the antivirus did not detect a potential threat or is simply disabled, use additional utilities. The Dr.Web CureIt! program is very effective in such situations. You can download this anti-virus utility on the official website of the Dr.Web laboratory. The program is free for treating home computers. The most important advantage of the utility is its high reliability: the program will work even if a virus tries to turn off the computer during the scanning process and block it.

Common problems with keyboard customization software

You may have configured a setting that changes the behavior of the keys. If the "Speak selected text when you press a key" option is activated, deactivate it or click "Change" to select a different key. If it is activated, you must hold the keys longer than usual for the action. In the Accessibility area, click Mouse and Trackpad. Make sure "Enable Mouse Keys" is turned off. If enabled, pressing the number buttons moves the pointer rather than the number. In the Keyboard panel, select Input Methods. Make sure the correct keyboard type is selected.

Problems with keyboard functionality such as calculator, sound or brightness settings

In the Accessibility area, click Speech on the Left.
Make sure the "Enable slow keys" option is disabled.

To get the latest version, click.

You can also recommend the development of Kaspersky studio, AVZ. Like Dr.Web CureIt!, the program is free. Updated regularly. It has several settings options, which allows you to most effectively identify not only viruses and spyware, but also possible system vulnerabilities. Quickly eliminates “computer infection” and gives many useful recommendations.

Identify your keyboard in this list or search in the search bar. Once you have identified your keyboard, tap or click on it to go to the download page. During installation, you may need to restart your computer one or more times. If you log in as a member of a guest group during the installation process, an error may occur.

Some computer manufacturers come with pre-installed keyboard customization software tailored to the keyboard that came with your computer.

Unplug your keyboard, then plug it back in.
If you are using a wireless keyboard, check your wireless connection.

If your device is supported, try the following.

The keyboard is simply not connected in the BIOS

Finally, the last reason for the “lifelessness” of the device is the lack of connection in the BIOS. This case is typical for netbooks and laptops, i.e. devices with a built-in keyboard. How to fix the situation?

Very simple. Turn off the computer, then turn it on again. Before the operating system starts loading, we load the BIOS. Typically you will need to click the Delete button to do this, but there may be other options. Sometimes the BIOS is activated by pressing the F2 or F8 keys (depending on the computer manufacturer). The hint at the bottom of the screen (if there is one) can help you determine which button to press.

Try the following tips. Some key commands require the installation of a specific program, such as an email program, web browser, media player, instant messenger program, or graphics editing program. Shortcut keys may not work as expected if you press a modifier key at the same time. If the correct program is not installed, you can still use the key by reassigning it.

If you have two wireless receivers connected to your computer and you press the same key on your wireless keyboard, you may see double characters on your screen. Some keys are designed to repeat when pressed and held. The following buttons can be repeated: previous, next, previous track, next track, volume, volume, zoom, zoom.

Then we find a tab in the BIOS that lists all input/output devices. Select the item called “USB Controller” and set the mode to “Enabled”. Go to the “USB Keyboard Setup” item and repeat the operation, setting the mode to “Enabled”. Then we confirm saving the changes and exit the BIOS. Reboot and test the keyboard.

Where are the standard function keys?

These keys are located on the top row of the keyboard. On some keyboard models they are tactile.

What to do if the computer keyboard and mouse do not work?

Why doesn't the keyboard and mouse work on my laptop? - This is another, fairly common malfunction, which happens quite often in the event of an unexpected failure in a south bridge laptop.

Very often the south bridge burns out in such a way that absolutely everything in the computer works except these above-mentioned devices.

But sometimes it happens that the laptop stops turning on altogether, or stops responding to the power button, precisely when the same south bridge in it burns out.

➤ This is cool: You still don’t know - it’s simple.

In this article we have to understand an important question: why does the keyboard not print? This phenomenon is not as rare as we would like. But you shouldn't be afraid of him. Problems are resolved without any problems. And only in some situations it is necessary to make a lot of effort to improve the functioning of the computer component. But for what reasons might the keyboard refuse to work? And what to do in this or that case?

Connector damage

The first case does not occur very often, but it does occur. Especially on older computers. For laptops, this situation is relevant only when we're talking about about a separately connected keyboard.

What is it about? Why doesn't the keyboard print? The problem may lie in the equipment connector. It sometimes breaks or gets damaged. In this situation, the keyboard cannot be connected. If you are using an older model (PS/2 socket), it is advisable to change the hardware to USB. Or connect the device to another connector. You can also try to repair the nests. But this technique will not provide a long-term guarantee of the device’s operation.

Drivers

Why doesn't the keyboard print? The next, more common reason is the lack of drivers for especially if we are talking about a multifunctional device with a large number of additional buttons. If the device refuses to work, it is recommended that you first reinstall the drivers for it. Or update them.

Typically, keyboards come with a disk with the appropriate software. Next And if the reason lay precisely in the drivers, then everything starts to work. You can additionally turn the device off and on after logging into operating system. But everything is not always as simple as it seems. After all, a computer is a device that can present various surprises. And fixing them is not always easy or simple. So what other options for the development of events can be identified?

Clogging

Why doesn't the keyboard print? This question sooner or later begins to worry almost every user. This is especially true for those who do not monitor the computer and its components at all. The keyboard does not print some letters? What to do? If we are talking about a device that has been working properly for at least a month, we can only advise one thing - to clean the component.

The keyboard is a device that can get clogged. Dust, food debris, crumbs - all this remains between the buttons. And we are talking about laptops and desktop computers. Therefore, all keyboards need to be cleaned from time to time. At least once a year. Or as needed. It is also recommended not to eat in front of the monitor. This technique will allow you to avoid clogging the connected device again. By the way, this problem is the most common scenario.

Now it’s clear why the keyboard doesn’t print. Just pay attention to the fact that you should not clean it yourself. Especially if we are talking about a novice user. And even more so, it is not recommended to clean the laptop keyboard yourself. It is better to take the input device to a service center. Almost everywhere offers keyboard cleaning services. In just a few hours, you can fix the problem that has overtaken the user. After cleaning, the keyboard will work at full capacity.

Rearrangement

But these are not all options for the development of events. Sometimes it happens that the keyboard prints the wrong letters. And in this situation it is very difficult to find an explanation for what is happening. After all, the device actually works. Just not the way it should be. There is only one reason that letters print numbers or not what is needed. This is an incorrect assembly of the device. If you disassemble the keyboard, you will notice that each button has its own mechanism. The computer receives a signal from a certain key and prints a particular character. For the convenience of the user, these mechanisms are labeled as buttons on the keyboard. If the latter are swapped, it appears that the device is printing the wrong characters.

Therefore, in this situation there is only one solution - to assemble the keyboard correctly. That is, place the mechanisms located under each key in the desired order. Doing this on your own is very problematic. Therefore, it is best to take the gadget to a service center. If you don’t want to think again about why the keyboard doesn’t print, you shouldn’t wipe and wash this component yourself. Often, problems with incorrect placement of buttons occur precisely after cleaning them yourself. Not the most dangerous, but not very pleasant moment either.

Incorrect assembly

Keyboard buttons not working? What should I do? First of all, don't panic. Secondly, analyze your recent actions with this device. In most cases, the user himself becomes the culprit of problems with components connected to the computer. What to do if If the user tried to figure out the device on his own, it is recommended to immediately take it to a service center.

The cause is incorrect assembly of the input device. Most likely, when the user tried to assemble the keyboard, an important contact came loose somewhere. This is not uncommon and should be kept in mind. You can fix this problem yourself. But users point out that in inept hands the keyboard will never work. Unless it is completely broken. And craftsmen usually manage to disassemble the device the first time and assemble it so that it works fully and without interruptions.

Marriage

What to do if the keyboard does not print? Much depends on the situation. If we are not talking about a new device, then the above scenarios may well be the reason for the failure of the component to work. But what to do when the conversation is about the keyboard you just bought? If all the drivers have been installed, the problem most likely has only one cause - a defect. And here only a complete replacement of the keyboard will help. It is recommended that you immediately contact the store where you purchased the device. There it will be possible to make an exchange. Otherwise, you will have to buy a new gadget.

Incompatibility

What to do if the keyboard doesn't work? You need to find out why the connected device refused to perform its functions. In fact, only in rare cases do users experience serious incidents as the cause. Much more often, all problems can be solved on your own.

Why doesn't the keyboard print? The whole point may be that the device is incompatible with the operating system. This problem appeared quite recently. Most often, users who have Windows 10 encounter this problem. With this operating system, older models do not experience a similar problem. Yes, the keyboard also has its own minimum requirements. And you should pay attention to them. Because you will either have to change the device eventually, or reinstall the operating system to one compatible with the gadget.

Viruses

Keyboard buttons not working? This device gave up work altogether? If all of the above cases do not apply, you can think about the last, rarest scenario - infection of the operating system. Viruses are the main enemies of the stable operation of computers. They can affect not only software, but also connected devices. For example, under their negative influence, the keyboard either does not print, or displays the wrong characters, or it even enters several letters/numbers per press.

There are two ways out: reinstalling the operating system from scratch or treating the computer for the corresponding infection. In the first case, you will have to completely format HDD, only then reinstall the OS. And the second option, as a rule, does not turn out to be effective enough. For this reason, it is recommended to save all data and reinstall the operating system on your computer. This way the virus will disappear 100%.

Have you ever had a situation when, while working at your computer, you suddenly noticed that the keyboard refused to type? And it doesn't matter whether you correspond in in social networks or print the most important work in your life: a diploma, a master's degree or a much more promising professorship. You are wondering why the keyboard on your computer does not work. You reboot the operating system in the hope that everything will fix itself, but it doesn’t. The keyboard, as before, does not respond. You start to panic. What to do? Should I call a technician to your home or buy a new keyboard? What if it's a laptop? There is an exit!

To fix this unpleasant breakdown, you first need to figure out what type of keyboard you have connected.

Computer keyboard connection type

USB keyboard. This type is the most common in our time. The USB keyboard uses plug-and-play technology (plug and play), so most often problems arise with the connection. As soon as the keyboard stops responding, the first thing you need to do is disconnect it and plug it back into the USB port of your computer device. Perhaps the contacts just went missing. Usually such actions lead to eliminating the problem. But it also happens that the breakdown is not in the keyboard itself. If these actions do not lead to positive result, there is a possibility that the port itself on the computer is broken. Try connecting the device to another device, or at least to a different USB port on your PC. Having completed these steps, you can already discard some of the guesswork about why the keyboard on your computer does not work. Windows XP, 7, Linux configure device connection settings differently. There is a possibility that the problem is in the software or operating system settings.

PS/2 computer keyboard. This type of connection has been used for a long time and is considered the most reliable, because it does not require driver installation. The keyboard connector has 6 pins for connection. It happens that if you connect a connector to a computer port inappropriately, one of the contacts may become bent. It needs to be aligned for the keyboard to work. If the keyboard stops working while working on it with the PC turned on, rest assured that the problem is in the operating system or software. Perhaps some process is slowing down its work. The main difference between a PS/2 computer keyboard and a USB one is that if the device fails, you must restart the computer for it to work again. After all, this is not plug-and-play technology.
A wireless keyboard is a modern type of input device, but that doesn't mean it's without flaws. It can also refuse to work like other types of devices. You may think for a long time why the wireless keyboard on your computer does not work, but the main breakdowns and problems most often arise when something blocks the USB receiver. In this case, you need to clear the computer desk of unnecessary things and see if it works now. Essentially, a wireless keyboard is the same USB peripheral device, with the only small difference: there are no wires. In this regard, it is necessary to first check the signal blocking. If no changes have occurred, then you must follow the steps described in the USB computer keyboard paragraph.

Troubleshooting the problem via BIOS

You have taken steps to mechanically correct the problem, but, unfortunately, this did not help. Panic covers you. Why doesn't the keyboard on my computer work? Windows 7, first of all, needs to be rebooted. Perhaps the problem will go away on its own.
Try pressing the Esc button several times to see if the display auto-start menu appears. If the program does not respond, you need to replace the keyboard - the problem is not in the software.
If the autorun menu works, press the F10 key to bring up the BIOS menu. In the settings you need to set the default values, this is done by pressing the F5 key. Some devices may have different hotkeys.
After making changes to the BIOS, you must restart the operating system.
If after these steps you still have not solved the problem and are asking yourself why the keyboard on your computer does not work, then you need to reinstall the keyboard software in Device Manager.

Reinstalling and configuring the keyboard software

In the control panel of any operating system in the Start menu there is a “Hardware and Sound” item, under which you can view devices and printers. This is exactly the section we need. Right-click in the window and select “Device Manager”. Do not forget that you must have administrator rights, otherwise you will not be able to change the settings of hidden devices. So, in the new open window we are looking for the required Keyboards item and trying to solve the problem of why the keyboard on the computer does not work. Windows 7, 8, XP have slightly different interfaces, so the path to the settings menu may be slightly different. When calling the object control panel, you must select the item to reinstall and update the hardware and driver configuration. After restarting the computer, the equipment should work correctly.

Problem pressing multiple characters with one keyboard key

Sometimes, while typing on the keyboard, a situation arises when the keys get stuck and several characters are typed at once. And the problem is not that you press the keys for too long. The whole point is in the keyboard response settings. To change these settings, you need to manually enter the word “keyboard” in the search bar in the Start menu. A new window will appear before your eyes; when you open it, you should correctly adjust the delay speed for entering a repeated character. From now on, you will not worry about why the keyboard on your computer does not work correctly.

1 way to fix keyboard inoperability outside the operating system

Often there are situations where the keyboard does not work due to incompatible drivers on the operating system. There are different versions of Windows: 32 and 64 bit. How are they different and why do they need different drivers? The main difference is in processing different volumes random access memory. This is why it is necessary to install Various types drivers so that at the most inopportune moment you don’t panic about why the keyboard on your computer doesn’t work. Windows 8, 7, XP, Linux require installation different types software. But to find out if this is the real cause of the problem, you need to restart the computer and watch, pressing the NumLock and CapsLock keys on the keyboard, check their functionality using the indicators that light up.

2 way to troubleshoot keyboard problems via CMOS

Another way to check the functionality of the keyboard outside the operating system is to go into the CMOS settings and try the keyboard in safe mode. Sometimes the operating system crashes, safe mode will fix this problem. If the CapsLock and NumLock keys fail, you must go to the first method.

A computer device beeps when typing from the keyboard: solutions

Why doesn't the keyboard on my computer work correctly? There are situations when, when working with a set of character characters, a computer device emits sound signals. In this case, you need to change your keyboard settings. To go to the settings, you need to register in search bar the word "Keyboard".

In the control panel results that appear, there is an option to change them. You need to follow this link, next to the “Make typing easier” item, uncheck the sticky keys checkbox and go to their settings. In the new window that opens, uncheck the box next to Sticky keys when pressing the Shift button five times. We save the results by clicking on the OK button, after which the previous keyboard settings window automatically opens. In it, uncheck the box next to the item for voicing switches by pressing the Num Lock button for 5 seconds. After saving the settings, the computer device will no longer produce meticulous beeps.

The numeric keypad refuses to work

Some users, when purchasing a peripheral device, sometimes wonder why the numbers on the keyboard on the right do not work. This situation happens quite often on a computer, especially in the operating room. Ubuntu system. What to do in this case? Try just pressing the two key combination: Shift + Num Lock. Most often this helps. There is a possibility that with numeric keypad Mouse control is configured. To disable it on the Windows operating system, you must press the key combination Alt + Shift + Num Lock. There is another, more complicated way to get to the optical mouse settings. But why complicate your life when pressing a keyboard shortcut can solve the whole problem?

Why the keyboard on the computer does not work when turned on: problem solving

To solve this problem, you must follow these steps:

Check the connection itself. It doesn't matter what type of keyboard: USB, wireless or PS/2. If there is a connection problem or signal loss, the keyboard will not work.
If everything is fine with the connection, you need to download new version software compatible with your operating system and reinstall it for your keyboard.
When reinstalling the driver did not help, it means that you need to configure everything manually through the BIOS, CMOS or Control Panel.
If it is possible to connect the keyboard to another computer device, check its functionality on it. In each operating system, software settings are located in different paths. It is necessary to know the operating system interface well in order to solve the problem of why the keyboard on the computer does not work. Windows 8.1 is perhaps the most complex system for configuring software changes. But you don't need a lot of knowledge to change keyboard settings. You must strictly follow the instructions, and then your peripheral device will work again as quickly as before.

Possible reasons for some keys on the keyboard not working

There are cases when, due to carelessness or carelessness, the user of a computer device spills water, tea or other drinks on the keyboard. And it’s good if the computer owner himself did this, because he knows where the problems with the peripheral device are coming from. But when someone else did it and did not admit it, the owner will scratch his head for a long time why the USB keyboard on the computer does not work. But most often it happens that certain buttons stop working. Then you need to disassemble and manually clean the keyboard, and if it has already oxidized, then completely replace it. After all, there is little chance that it will now work as before.

Note to users

Now you know possible reasons computer keyboard failure. It will be new to some users to learn that any operating system automatically installs an on-screen keyboard. In case of failure of work peripheral device it will definitely help you.

In this article we have to understand a rather important question: for what reasons can the keyboard stop typing? This phenomenon is actually not that rare. But don’t get scared ahead of time. Problems with I/O devices can be resolved without much hassle. And only in some situations you have to seriously try to restore the functionality of this computer component. But for what reasons can the keyboard refuse to function? What to do in this or that case?

Physical damage to the connector

The first problem does not occur too often, but it does occur. Owners of old computers especially often encounter this problem. For laptops, this arrangement is only relevant if we are talking about a separately connected keyboard. What are we talking about in this case? Why does the keyboard refuse to type? The problem may be a faulty equipment connector. Sometimes it gets damaged or broken. The keyboard simply cannot be connected in this situation. If you are using an older model of personal computer with a PS/2 socket, then it would be better to change the hardware to USB. You can also try connecting the device to a different connector. You can also try to repair the sockets yourself. However this technique does not guarantee long-term operation of the device.

Drivers

Why does the keyboard refuse to type? One of the most common reasons for such problems is the lack of necessary drivers for input devices. This is especially true in cases where a multifunctional gaming keyboard with a lot of additional buttons. If the device refuses to work, then the first thing we recommend is to try reinstalling or updating the drivers for it. As a rule, multifunction keyboards come with a disc containing the appropriate software. After this, you need to restart your computer. If the reason was the drivers, then after these procedures the keyboard should start working normally. You can also try turning off and on the device after logging into the OS. However, in reality this is not as simple as it might seem at first glance. A personal computer is a very complex device that can present various surprises. Fixing them is not always easy. For what other reasons might the keyboard refuse to type?

Clogging

Why doesn't the keyboard work? Sooner or later, this question begins to worry many users. This especially applies to those who do not pay due attention to caring for their computer and its components. What to do if the keyboard does not print some letters? If we are talking about a device that has previously worked properly for more than one month, then we can recommend cleaning the keyboard. After all, the keyboard is a device that can easily become clogged. Dust, crumbs, and food debris may remain between the buttons. In this case we are talking about both laptops and desktop computers. For this reason, all keyboards need to be cleaned from time to time. Conduct this procedure preferably at least once a year or as needed. It is also recommended not to eat in front of the monitor. This will reduce the likelihood of clogging the connected device. It is worth noting that this problem is the most common scenario. Now it should be clear to you why the keyboard refuses to print. It is worth paying special attention to the fact that experts do not recommend cleaning the keyboard yourself. This is especially true when it comes to novice users. And, of course, it is not recommended to clean the laptop keyboard yourself. It is better to take the device to a specialized service center. Any such center offers keyboard cleaning services. The problem can be fixed in just a few hours. The keyboard will work at full capacity after cleaning.

Reinstallation

These are not all possible scenarios. In some cases, it happens that the keyboard prints the wrong letters. Finding an explanation for everything that happens can sometimes be very difficult. After all, the device actually works, but not quite as it should. There is only one reason why the keyboard prints the wrong characters - incorrect assembly of the device. If you take the keyboard apart, you will notice that each key has its own special mechanism. The computer receives a signal from a specific key and prints a specific character. To ensure user convenience, these mechanisms are labeled as buttons on the keyboard. If these mechanisms are swapped, then it seems that the device is printing the wrong characters. There can only be one way out of this situation - to assemble the keyboard correctly. To do this, you need to place the mechanisms that are located under each key in the required order. Performing this procedure yourself is very problematic. It would be best to take the device to a specialized service center. If you don’t want to think again about why the keyboard doesn’t print, then you need to wash and wipe this component from time to time. Problems with incorrect button placement often occur after cleaning the keyboard yourself. This is not the most dangerous problem, although it is a little annoying.

Incorrect assembly

What to do if the buttons on your keyboard do not work? First of all, don't panic. Try to analyze your latest actions with this device. In most cases, the user himself becomes the culprit of problems associated with components connected to the computer. What to do if the keyboard refuses to work? If the user tried to disassemble the device on his own, it is recommended to immediately take it to a service center. The reason is that the input device is not assembled correctly. The user most likely tried to assemble the keyboard, but some important contact came loose somewhere. This phenomenon occurs quite often. It is quite possible to fix the problem on your own. However, users point out that the keyboard will not work in the wrong hands, and may even be completely broken. Craftsmen are usually able to disassemble the keyboard the first time and assemble it so that it works without interruption.

Marriage

What to do if the keyboard does not print? A lot depends on the situation here. If in this case the problem did not arise with the new device, then the scenarios listed above may well be the reason for the failure of this component to work. However, what to do if we are talking about a new, just purchased keyboard? If all the necessary drivers have been installed, then the problem is most likely a manufacturing defect. In this case, only a complete replacement of the keyboard will help. You must contact the store where you purchased the device. There you can immediately exchange it. Otherwise, you'll just have to buy a new gadget.

Incompatibility

What can you do if the keyboard does not work? You need to find out why the connected device refuses to perform its basic functions. In fact, in rare cases, serious incidents are the cause of problems. All problems can often be solved on your own. If the keyboard refuses to type, then the problem may be that the device is incompatible with the operating system. This kind of problem appeared relatively recently. This is most often encountered by users working with operating systems. Windows system 10.Older keyboard models simply do not work with this operating system. This problem does not occur on laptops. In addition, the keyboard also has its own minimum requirements. You should pay special attention to them. Ultimately, you will have to either change the device or reinstall the operating system that will be compatible with the gadget.

Viruses

Keyboard buttons refuse to work? Is your device not functioning at all? If all the situations described above do not apply, then you can consider the last, rarest scenario - infection of the operating system. Malicious objects and viruses are the main enemies of stable operation personal computers. They can influence not only software, but also connected devices. For example, under their negative influence, the keyboard may not print or display the wrong characters on the screen. Also, sometimes there are situations when the keyboard writes several letters/numbers at a time. There can be two ways out of this situation: reinstalling the operating system from scratch and treating the computer for the corresponding infection. If you choose the first option to solve the problem, you will need to completely format the hard drive and then reinstall the operating system. As a rule, the second option is not very effective. For this reason, it is recommended to save all information and reinstall the operating system on your computer. In this way, you are guaranteed to get rid of the virus.

The keyboard is the main tool when working on a computer, without which work is almost impossible. Of course, you can enter information using a mouse and on-screen keyboard, but this method is inconvenient and full-fledged work will not work.

In this article we will tell you what to do if the keyboard on your computer does not work and consider all the possible causes of this malfunction.

The keyboard is a fairly simple device and usually works flawlessly. However, there are times when the keyboard indicator lights up, but nothing is printed.

Why the keyboard doesn't work: reasons

There are two types of reasons why a computer keyboard may not work:

Mechanical (cable break, moisture ingress, excessive contamination of the keyboard, violation of the integrity of the connection ports, and so on).
Software (software failures, incorrect BIOS settings, incorrect keyboard drivers, and so on).

Let's look at all the main reasons why the keyboard does not work and troubleshooting methods.

Problem with the cable or keyboard port

The first step is to assess the physical condition of the keyboard.

Look at the button indications Caps Lock and Num Lock. Most likely, if they work, then physically everything should be fine with the keyboard.

Visually inspect the keyboard cable. It may be pinched or cut. For example, many pet owners have pets that chew cables.

Also, visually check the keyboard connection port to see if there are any fractures or bends in it. There are two types of keyboard connection ports - USB and PS/2.

It often happens that when people try to connect to a computer in a PS/2 port, they break off the tip of the wire and the keyboard does not connect.

If externally the cable USB keyboards s and the connection port look good, then try plugging the keyboard into another port Computer USB. The port on the computer itself may be damaged. If the keyboard works in another port on the computer, then you have a problem with USB port. Usually there are several of them on the computer and you can simply leave the keyboard connected to the port that works.

In the case of a keyboard with a PS/2 port, you should check the functionality of the keyboard connection port on another computer, since such a port on motherboard only one. To test the functionality of your computer's PS/2 port, you will have to find another such keyboard.

Spilled liquid and dirt on the keyboard

A flooded keyboard is a headache for all IT specialists and a goldmine for all laptop repair service centers. Very often, when working on a computer, people pour tea, coffee, beer and other liquids onto the keyboard. As a result, the keyboard may fail.

As a rule, it is easy to determine visually and by smell that liquid has been spilled on the keyboard. Carefully inspect the keyboard. Remove a couple of keys. If you see that there are traces of spilled liquid or food on the keyboard or under the keys, then you have two options. Either buy a new keyboard, or meticulously disassemble the flooded keyboard, clean it, dry it and put it back together. With a high degree of probability, the keyboard will work.

Previously, we have already talked in detail about what is at home.

Checking USB settings in BIOS

In the event of a computer power failure, the BIOS settings may change, which contains an item about enabling and disabling USB support keyboards on a computer.

Additionally, in this way you can check the serviceability of the keyboard in principle, since it may not work in Windows, but work in the BIOS. In this case, the failure is caused by software or drivers.

To enter the BIOS and check the settings, do the following:

Turn on your computer.
Press the DEL button on your keyboard until the BIOS settings window appears.
In the BIOS settings, find the USB Keyboard Support or Legacy USB menu.
Make sure the setting is in the Enable state. If it says Disable, then switch to Enable.

You can also set the remaining BIOS settings related to USB to Enable. You may be able to get ports on the front panel of your computer case that once stopped working.

Software or driver failure

Keyboards with older PS/2 connectors are more susceptible to software glitches. However, there are still quite a lot of such keyboards in use, although manufacturers have almost stopped producing them.

To resolve the problem of your keyboard not working due to software, you need to turn on your computer and log into your desktop. Since the keyboard has stopped working and does not print, but account a password may be set, you will need to use on-screen keyboard and type the password with the mouse.

Now that you are on the desktop of your computer, you need to get to Device Manager.

In Windows 8 and Windows 10, to do this, right-click on the button Start and select device Manager.

In Windows 7, left-click on the button Start. Next, right-click on the word Computer and select Computer management — device Manager.

Device Manager displays information about all devices on your computer. Expand the Keyboards branch. If there is an orange question mark next to your keyboard, it means the device is not installed correctly on the system.

Right click on your keyboard and select Delete.

The computer will rescan all devices and install the keyboard correctly.

Factory defect or keyboard has reached the end of its service life

Any technology tends to break down and fail. If the keyboard was purchased relatively recently, then you may have encountered a manufacturing defect. In this case, you can contact the keyboard manufacturer's support service and expect a replacement device.

The fact is that many manufacturers value their reputation and, without entering into long debates with the buyer, immediately send a brand new keyboard by mail.

If you have had the keyboard for more than a year, then most likely it has failed due to service life and you should buy a new one.
