Of course, this is not the most common situation, but it does happen from time to time: the user turns on the computer, the download is successful, and then it is discovered that the keyboard does not work.
Moreover, it is completely incomprehensible why this happened and how to get out of the situation now. Maybe you need to call a specialist or, worse, format the disk and reinstall Windows? Do not rush to panic, most likely, you will cope on your own.
The simplest and most common cause of keyboard failure, which can be eliminated in just a couple of seconds - the PS / 2 plug fell out of the socket for some reason. Perhaps an accident of this kind has four legs, a tail and a cheerful disposition.
Maybe the keyboard cord was pulled out during cleaning. In a word, the first thing to do is to check the position of the plug in the socket, remove and insert it back, after which, if the situation remains unchanged, restart the computer.
However, other cases should not be ruled out - for example, a virus attack. You can run an anti-virus scan using mouse clicks. If she did not find anything, then the problem is more serious - either the keyboard connection port has burned out, or the keyboard itself has malfunctioned.
Although extremely rare, it still happens sometimes. You can check this assumption by connecting another, obviously working keyboard. If this did not help, then there is no choice, the next step will be testing with professional equipment.
No words, the wireless keyboard is a convenient invention, but it has one drawback common to all wireless gadgets: it needs to be charged. If you forget to charge your keyboard on time, it is not surprising that it refuses to work.
A new, not yet working wireless keyboard requires the installation of its driver. Typically, the computer itself finds the desired driver in the memory, or the driver disk comes to the device in the kit. 
But sometimes in automatic mode the driver is not installed, and then you have to perform a manual search and installation.
The same thing is done if the driver was removed for some reason - it crashed, as experts say.
The USB keyboard differs from the usual one only with a connector for connection - it is easy to guess that it is a USB connector. Therefore, the verification algorithm is approximately the same as for a keyboard with a PS / 2 connector:
- checking the reliability of the contact;
- anti-virus scan;
- connecting a working keyboard;
- testing using special equipment.
However, another option is possible - changing the BIOS settings. To enter the BIOS, you need to start the boot and press the appropriate key, most often it is Del or F6, and find the tab in which the I / O devices are displayed.
Opposite the “USB Controller” item, set the “Enabled” state, then go to the “USB Keyboard Setup” item and also set “Enabled” opposite it, that is included. After that, exit the BIOS, do not forget to confirm the saving of the changes made.
The numeric keypad is located to the right of the main one. It is not available on all types of keyboards and is almost never used by most users. 
If you still have it, and suddenly you need to turn it on, you just need to press the “Num Lock” button, which is usually located in the top row of the numeric keypad.
Failure of half the keys is most characteristic of the so-called multimedia keyboard, on which multimedia adjustments (sound, brightness, color reproduction, etc.) are implemented as button controls.
This multimedia part sometimes fails after loading due to disconnection of the multimedia key switching service. The cause may be a surge in power supply, hardware failure and other computer malfunctions.
This problem is resolved very easily. Need to:
- go to the Start menu;
- select "Control Panel";
- select "System and Security";
- select "Administration";
- select "Services";
- select "Access to HID devices" and right-click;
- select "Properties" in the pop-up menu;
- select the “General” tab and click on the “Run” button. 
In order to eliminate the possibility of service outages in the future, the following should be done:
- select the “Recovery” tab;
- find the line “Subsequent failures”;
- click the “Restart service” button;
- click “Apply” and “OK”.
After that, in the event of a failure, the multimedia buttons will start automatically.
Probably, each of us faced a similar situation: you turned on the computer, 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 caused this behavior of the device? Why does the keyboard not work on my computer or laptop? And how to fix it? Consider what could be the reason.
In fact, this is extremely inconvenient compared to others, since this requires an excess of finger movement. Another standard is Dvorak. In addition, there are two other standards created for those who need to enter only one hand. Take a look now at some keyboards that can make you spend hours admiring a window in a store.
Usually they have additional features compared to conventional keyboards. You should notice in the photo that there is still a mouse on the back of the touchpad-style periphery. Who needs practicality, wants to have it. The keyboard below looks strange, but it makes the eyes of many gamers and graphs shine 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 safely forgot about it. In this case, all that remains for you to do: disassemble the device and try to fix it yourself, or contact service center . The second option is preferable, especially when it comes to a laptop keyboard. If the keyboard "bring back to life" does not work, you have to purchase a new input device.
Do your friends watch what you print and call you “photographer”? It has both wired and wireless options and is available in Brazil. But this does not stop there, since the keys can be configured to display symbols of tools, commands, programs, or even images made by you. Maybe in Portuguese we could have a keyboard that would better suit our needs and would cause less pain in the hands of those who use the equipment for long hours in a row?
Why in Brazil no keyboard manufacturer has proposed to this day to change the standard that makes life easier for users? With so much success in software interfaces to make it easier for the user because the keyboard is stopped on time?
Contact failure
Sometimes, keyboard malfunctions are caused by improperly connecting the device to the computer. Check if the plug is firmly inserted into the socket on system unit if 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, you should check to see if the battery is dead in it. Very often, the problem disappears without a trace as soon as the power supply is replaced.
Feel free to give your answers and explain your theories using the feedback system. If your keyboard no longer works, there are a few things you can check to solve this problem. Depending on the situation, you can try one of the following options: you must first identify two important factors in this solution for troubleshooting.
Your keyboard no longer works
The problem occurred during input, or you noticed it immediately after starting the computer. In addition to extreme situations, such as spilling water on the keyboard, the answer to this question is important to identify the problem. If you notice that your keyboard has stopped working after booting or, check the connection to the 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 software your computer.
You can do this manually by visiting the website of your keyboard manufacturer.
Which keyboard are you using?
Turn off your desktop computer and see if it works. Also check the batteries, maybe it's 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 the keyboard to receive the signal sent by the receiver and flow with each other.
In a sense, these keyboards are more reliable because there are no drivers to install from operating system . If it stops working when using the operating system, in most cases the problem does not occur from 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, wait until the operating system finishes.
- On the Application tab, select everything and click Finish Task.
- A confirmation window will appear asking you to stop it.
- Click Finish Task again and wait for it to complete.
Manual driver update
- go to the official website of the manufacturer;
- we find the appropriate section, select your device model;
- download the archive and unpack it. Sometimes the driver has its own automatic installation program, in which case you will just need to click "Run file";
- if a automatic program no, run the “Device Manager”;
- select "Update drivers", in the dialog that opens, select manual search, specify the path to the folder into which you unpacked the archive;
- after installation, restart 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 windows computer 7 or another OS. You don’t have to search for manufacturers' sites, but you will need to install additional programs for updating drivers. For example, Driver Genius Professional or Driver Checker. These utilities are paid, but if you wish, you can find them a replacement among free software (DriverMax Free, etc.).
If your keyboard no longer works, but you have a good second known keyboard with the same type of connection, replace the correct keyboard with the wrong one and see if it works. You can also try to connect the wrong keyboard to another computer and determine if the keyboard is broken.
Wireless Keyboard Troubleshooting
If some keys on the keyboard work, but not all, follow these steps to suit your situation. The eject button mechanism starts after a short delay to avoid accidental use. Press and hold until the eject icon appears on the screen.Viruses attacked
Sometimes the operation of input devices is blocked as a result of activities malware . If you don’t know why the keyboard does not work on a laptop or computer, and with it the touchpad and mouse, then it is most likely a virus infection of the system. What to do in this case?
and how can I fix it? Forgot your computer password? Do not worry - in our article you will find information on how to restore it.
Check your system with antivirus as soon as possible. If the antivirus does not detect a potential threat or simply shuts down, use additional utilities. The Dr.Web CureIt! Program is very effective in such situations. Download this antivirus utility possible on the official website of Dr.Web Laboratory. For the treatment of home computers, the program is free. The most important advantage of the utility is its high reliability: the program will work even if the virus tries to turn off the computer and block it during the scan.
General issues with keyboard setup software
You may have configured a setting that changes the behavior of the keys. If the option “Speak selected text when pressing a key” is activated, deactivate it or click “Change” to select another key. If 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 activated, pressing the number buttons moves the pointer, not the number. In the Keyboard panel, select Input Methods. Make sure the correct keyboard type is selected.
Keyboard functionality issues such as calculator, sound or brightness settings
- In the Availability area, click Speech on the Left.
- Make sure the Enable Slow Keys option is disabled.
You can also advise the development of Kaspersky studio, AVZ. Like Dr.Web CureIt !, the program is free. Updated regularly. It has several configuration options, which allows you to identify as efficiently as possible not only viruses and spyware, but also possible system vulnerabilities. Quickly eliminates the “computer infection”, gives many useful recommendations.
Define your keyboard in this list or search in the search bar. Once you have identified your keyboard, click 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 guest group member during the installation process, an error may occur.
Some computer manufacturers have preinstalled keyboard customization software adapted to the keyboard that comes with the computer.
- Disconnect the keyboard, then reconnect it.
- If you are using a wireless keyboard, check the wireless connection.
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. Usually for this you need to click the Delete button, but there may be other options. Sometimes the BIOS is activated with the F2 or F8 keys (depending on the computer manufacturer). The help at the bottom of the screen (if there is one) can help determine which button to press.
Try the following tips. Some key commands require the installation of a specific program, such as a program. email , web browser, media player, instant messenger or graphics editing program. Shortcuts may not work as expected if you press the modifier key at the same time. If the correct program is not installed, you can still use the key by reassigning it.
If two wireless receivers are connected to your computer and you press one key on the wireless keyboard, double characters may appear on the screen. Some keys are designed to be repeated when pressed and held. The following buttons can be repeated: previous, next, previous track, next track, volume, volume, zoom, zoom.
Then we find in the BIOS a tab that lists all the input / output devices. Select the item with the name "USB Controller", set the mode to "Enabled" ("Enabled"). Go to the "USB Keyboard Setup" and repeat the operation, set the mode to "Enabled". Then we confirm the saving of the changes and exit the BIOS. Reboot and test the keyboard.
Where are the standard function keys?
These keys are located in the top row of the keyboard. On some keyboard models, they are tactile.
Button "Print". screen does not work
If you hold down the Gadgets key, that's it open windows will be transparent, allowing you to see gadgets on your desktop. In other versions or themes, when you press or hold the Gadgets button, you browse the desktop. Button "Print". the screen copies the screen image to the clipboard. . On some keyboards, the My Favorites keys are secondary.Sometimes the BIOS does not support USB keyboards. In this case, it is better to entrust the computer setup to professionals from the service center, since it is necessary to reinstall the BIOS. Doing it yourself is quite difficult.
The exact causes of this malfunction can be only two:
The standby key puts the computer in power management mode only if the computer supports power management and power management is turned on. If it is not activated, this button does not work. It cannot be reassigned. You can resume work by doing one of the following:
- Press the wait key.
- Press the standard key on the keyboard.
- Move the mouse.
- Quickly press the power button on the computer.
- Then click it again.
- Restart your computer and press the Home key.
- hardware (in the case when the device itself or the port to which it was connected failed);
- software (failure to load the correct driver).
If the keyboard is out of order, then there are only 2 ways: replace it with a working one or repair it.
- For starters, of course, you can try restarting the computer. It is possible that after a reboot, it will work again.
- If the reboot did not help, then you can use the keyboard with the mouse (while it should work fine).

Why does the keyboard on the laptop not work with the mouse? - This is another, quite common malfunction, which quite often happens during an unexpected failure in a laptop of the south bridge.
Very often, the south bridge burns out in such a way that absolutely everything except the above devices works in the computer.
But sometimes it happens that the laptop does not turn on at all, or react to the power button, precisely when the same south bridge burns in it.
➤ It's cool: you still don't know - it's simple.
Probably, each of us faced a similar situation: you turned on the computer, trying to enter text on the keyboard or switch from one window to another, but the keys do not respond to pressing, ...
Fortunately, at the moment the keyboard is such a popular device that you can buy it even in a regular supermarket, not to mention specialized stores. Despite the simplicity of this gadget, it can cause problems and malfunctions. One of the most famous problems sounds something like this: "the keyboard has stopped working." that's just stopped and that's it. Today I will talk about why this can happen and how to cope with problems. It should also be added that in this case we will talk about a computer keyboard, and I will discuss a keyboard for a laptop next time, since there is a big difference between them.
Causes of problems and solutions
Where to start? First of all, you can’t panic. Yes, that's right, because in 90% of cases your problem is very easily solved.
- If you have a pet that loves to climb everywhere, I recommend that you look at the back wall of the system unit. It is possible that a cat passing by touched the keyboard plug and it simply fell out of the socket.
- The next possible option is a certain glitch that occurred in the operating system. For such cases, there are two solutions to the problem. Firstly, disconnect the plug for a few seconds and insert it back, and secondly, you can restart the computer if the first option did not help. After rebooting the PC, the device starts to work in 90% of cases.
- If you are using a PS / 2 keyboard, then carefully examine the connector itself. The fact is that his legs could bend, which must be leveled, otherwise he will not work. To do this, tweezers (ideally) or something sharp like knitting needles are suitable for you.
- Most modern keyboards (like) are connected to a PC based on a modern USB system. It is recommended to change the USB port and check the operation of the device. Ideally, its performance is best checked on another PC or laptop.
- It is theoretically possible that the keyboard ordered a long life, in other words, it fell into disrepair. However, in practice this happens very rarely, and often only one or more buttons fail. It’s easy to check - connect the device to another computer or laptop.
- One of the funniest problems is the introduction of numbers - users complain that the right side of the gadget where the numbers are located does not work. In fact, it is connected by request with the Num Lock button, which is located above the numbers. This is done in order not to accidentally click on the numbers.
- Often on the keyboard in those places where the buttons are located, the rubber band, which is located inside the case, slides. Sometimes various crumbs and other small objects get on it. To get rid of them, the keyboard must be disassembled and cleaned. By the way, large crumbs can fall under one of the keys and it will stop being pressed. In this case, it is enough to remove only one key, which, fortunately, is very easy.
- If you have a fairly expensive keyboard with many additional buttons, you probably need to install separate drivers. Without them, the keyboard can and will work, but except for individual buttons. You must install the drivers for the device, which can be found on the official website of the manufacturer.
- By the way, about the drivers. In some cases, the problem arises not with the keyboard itself, but with the driver, which is responsible for its operation. It may have been damaged. This problem can be solved in two ways: either we update the drivers to the latest version, or a few days ago when the keyboard worked.
- If you just purchased a computer and have never used it before, try logging into BIOS - perhaps keyboard support is disabled. In the BIOS menu, you need to find an item called USB Keyboard Support and move it from Disabled to Enabled.
- If you use a wireless device (keyboard) that runs on batteries, do not forget to charge it. Probably, it just ran out of power, and therefore stopped working.
- And users often complain that the keyboard does not work in games or programs. Fortunately, in most cases, this problem is easy to handle. The fact is that, by default, the control is programmed for certain keys, which you can change at your discretion. To do this, go to the game settings. The same fully applies to.
Finally, I remind you once again that in most cases you can solve the keyboard problem yourself. Well, if she still refused to work, then she would have to spend money on buying a new one, because the repair of this device is usually unreasonably expensive.
Many are often interested in why the keyboard does not work on the computer, as well as letters or numbers on it. We will help you solve this problem.
The keyboard does not work at all
Possible reasons
- Cable break
- Lack of connection
- Lack of BIOS support
- Pollution
How to fix?
- Check cable for kinks. Also check the plug, maybe it just fell out of the connector, or the studs bent in it, but this is if you have a keyboard with a PS / 2 connector.
- Check its performance in the "Device Manager", which is located in the "Control Panel". Find the keyboard there. If she is not there, then it probably does not work at all or the computer cannot find her driver. Therefore, pull out the keyboard and insert it again.
- For a keyboard equipped with a USB connector, there is another option. Connect the working keyboard to the computer and enter the BIOS. To do this, immediately after turning on the PC, you need to press the Delete key (the key can be any, but, as a rule, this is Delete). Find there an item called “USB Keyboard Support” (it may be different, but the first 2 words should be “USB Keyboard”). Then activate this item by selecting Enabled and restart the computer.
- Clean the keyboard of dirt. To do this, turn the keyboard upside down and shake it well. So you shake out solid debris, such as crumbs or hair, from the keyboard. You may have to disassemble the keyboard. Turn it over with the keys on the table, unscrew the screws on the bottom of the keyboard. Try not to lose the cogs! Then, carefully remove the bottom without shaking the keyboard, otherwise you will lose the keys and also find another problem. Now remove the small board and clean the contacts on it. Then, remove and inspect the contact films, which should be 3 pieces, if they are wet or contaminated with something (of course, if they are clean, it is better not to do anything with them), gently wash them in warm water, wipe with a dry cloth and leave dry, then collect everything back.
Numbers or block of numbers do not work
Possible reasons
- Cable break
- Lack of connection
- Disabled digital block (or Numpad)
- Pollution
How to fix?
- Inspect the cable and plug.
- Then check the status Num lockif the indicator is off, then you just need to turn it on.
- Alternatively, you have the option to control the cursor from the keyboard turned on in your system, then you should turn it off. We go to the address Start - Control Panel - Accessibility - Mouse, there we remove the checkbox (checkmark) "Control from the keyboard."
- And if nothing worked for you, perform the cleaning procedure described above.
Letters do not work
Possible reasons
- Cable break
- Lack of connection
- Lack of settings in the game
- Pollution
How to fix?
- According to the already installed algorithm, check the cable with the plug.
- If this problem has overtaken you, for example, in a game, then go to the game settings and assign keys to actions, because they may simply not be configured.
- Finally, clean the keyboard.
We hope that we were able to help you. Take care of your keyboard and it will serve you for many years!
In this article, we have to figure out an important question: why does not the keyboard print? This phenomenon is not as rare as we would like. But you should not be afraid of him. Problems with are resolved without any problems. And only in some situations it is necessary to try pretty hard to establish the functioning of the computer component. But for what reasons can the keyboard refuse to work? And what to do in this or that case?
Connector damage
The first case is not too common, but it does occur. Especially on older computers. For laptops, this layout is relevant only when it comes to a separately connected keyboard.
What is this about? Why doesn't the keyboard print? The problem may lie in the equipment connection jack. It sometimes breaks or is damaged. In this situation, the keyboard cannot be connected. If you are using an older model (PS / 2 jack), it is advisable to change the equipment to USB. Or connect the device to another connector. You can also try to repair the nests. But this technique will not give a long guarantee of the operation of the device.
Drivers
Why doesn't the keyboard print? The next, more common reason, is the lack of drivers for Especially when it comes to multi-function, with a lot of additional buttons. If the device refused 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. Further And if the reason was precisely in the drivers, then everything starts to work. You can optionally turn off and on the device after entering the operating system. But not always as simple as it seems. After all, a computer is a device that can present a variety of surprises. And not always correct them easily and simply. So what other scenarios can be highlighted?
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. Does the keyboard not print some letters? What to do? If we are talking about a device that has worked for at least a month, you can only advise one thing - to clean the component.
The keyboard is a device that can clog. 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 out of necessity. It is also recommended not to eat in front of the monitor. This technique will not clog the connected device once again. By the way, this problem is the most common scenario.
Now it’s clear why the keyboard does not print. Just pay attention to the fact that you should not clean yourself. Especially when it comes to a novice user. And even more so, it is not recommended to clean the keyboard from the laptop ourselves. It is better to take the input device to a service center. Almost everywhere keyboard cleaning services are offered. In just a few hours, you can fix the problem that overtook the user. After cleaning, the keyboard will work at full strength.
Rearrangement
But these are far from all scenarios. Sometimes it happens that the keyboard types the wrong letters. And in this situation it is very difficult to find an explanation for what is happening. Indeed, the device actually works. Just not as it should. The reason that letters print numbers or not what you need is just one. This is an incorrect assembly of the device. If you take apart the keyboard, you will notice that each button has its own mechanism. The computer receives a signal from a specific key and prints one or another character. For the convenience of the user, these mechanisms are signed in the form of buttons on the keyboard. If the latter are interchanged, it seems 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 under each key in the desired order. It is very problematic to do it yourself. Therefore, it is best to take the gadget to a service center. If you do not want to think once again why the keyboard does not print, you should not wipe and wash this component on your own. Often the problem with the wrong arrangement of buttons happens precisely after self-cleaning. Not the most dangerous, but not too pleasant moment.
Incorrect assembly
Keyboard buttons do not work? How to be First off, do not panic. Secondly, analyze your last 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 the user tried to figure out the device on his own, it is recommended that you immediately take it to a service center.
The reason is the incorrect assembly of the input device. Most likely, when the user tried to assemble the keyboard, an important contact went away somewhere. This is a common phenomenon that should be remembered. You can fix this problem yourself. But users indicate that in inept hands the keyboard will not work. Unless it will be finally broken. And the craftsmen usually get the first time to disassemble the device 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 options for the development of events may well be the reason for the failure of the component from work. But what about when the conversation is about the keyboard you just bought? If all the drivers have been installed, the problem most likely has only one reason - marriage. And only full keyboard replacement will help here. It is recommended to immediately contact the store where the device was purchased. There it will be possible to conduct an exchange. Otherwise, you will have to buy a new gadget.
Incompatibility
What to do if the keyboard does not work? Find out why the connected device refused to perform its functions. In fact, only in rare cases do users have serious incidents. More often, all problems can be solved independently.
Why doesn't the keyboard print? The whole thing may be in the incompatibility of the device with the operating system. This problem has appeared recently. Most often, users who have Windows 10 encounter it. With this operating system, older models do not experience a similar problem. Yes, the keyboard also has its own minimum requirements. And they should be paid attention to. Because you either have to change the device in the end, or reinstall the operating system to a compatible gadget.
Viruses
Keyboard buttons do not work? Has this device refused to work at all? If all of the above cases are not suitable, 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 puts down a few letters / numbers at a time.
There are two ways out: reinstalling the operating system from scratch or disinfecting the computer from the corresponding infection. In the first case, you will have to completely format the hard drive, only then reinstall the OS. And the second option, as a rule, is not sufficiently effective. For this reason, it is recommended that you save all the data and reinstall the operating system on the computer. So the virus will 100% disappear.
