The keyboard on my computer has stopped printing, what should I do? Why doesn't the keyboard print? Possible causes of problems and their elimination

There can be only two exact reasons for this malfunction:

hardware (in the case when the device itself or the port to which it was connected failed);
software (failure to load the required driver).

If the keyboard fails, then there are only 2 ways: replace it with a working one or repair it.

To begin with, of course, you can try restarting your computer. It is possible that after a reboot it will work again.
If rebooting doesn't help, you can use the keyboard with the mouse (it should function fine).

Step by step steps to fix the problem:

Start button -> then Settings -> after Control Panel -> System;
click System Properties -> then Hardware -> Device Manager;
in the window called "Device Manager" highlight the large yellow circle with a black exclamation mark;
select Action -> then Delete from the menu;
in the “Device Removal Confirmation” window, you need to authorize the removal of the keyboard by clicking OK;
close Device Manager;
in the window called System Properties, on the Hardware tab, you need to click the Install Hardware button;
in the window that opens called Hardware Installation Wizard, click Next;
after a short search for the equipment, your keyboard should be “found” (the Num Lock indicator will turn on);
After performing these steps, the Changing system parameters window should appear with the message “Installation of new devices is complete.”
The last action will be to click Finish in the Add Hardware Wizard window.

What should be the action if several or one button stops working?

If some keys on your keyboard stop working, it is quite possible that the keyboard driver requires updating or is missing altogether.

If you purchased a software disc in the same package as the keyboard, you should use it when reinstalling the necessary drivers.

Otherwise, follow the instructions to update the drivers.

To get started, click the Start button and select Keyboard, Control Panel, and Hardware and Sound.
In the Hardware window, you need to find the keyboard you are using and double-click on it.
Then on the Driver tab you need to click Update and follow all the instructions.
Answer yes to the pop-up prompt to restart your computer.

Why doesn't the keyboard print? In cases when a wireless keyboard stops working, you need to perform the simplest steps in strict order, and after each action, check the device for working condition:

First of all, if there is a switch at the bottom of the keyboard case, you definitely need to make sure that the “On” position is set.

Then restart your computer. Such actions will help to eliminate the problem that has arisen for a short time in order to eliminate all problems.

The next action is to move the device closer to the receiver.

Now you need to make sure that the keyboard is no further than 30 cm from the receiver.

If the receiver is firmly attached to the cable, you can position it so that it is at the same level with the keyboard.

Try replacing the batteries with a good set of newer alkaline batteries and then make sure the drivers are installed correctly.

If this does not help, replace all batteries, even if the tested software keyboard indicates the presence of charge.

How to “cure” a flooded device at home?

At the very beginning, you need to cover the keyboard (from the buttons side) with small polyethylene and secure it with tape on all sides.

Is it possible to connect wireless keyboard to a constantly running computer (server)?

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. It is advisable to carry out this procedure at least once a year or as necessary. 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 recent 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. Eventually you will have to either change the device or reinstall operating system, which 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 HDD 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.

If you do not need a password, but to log into his account, then:

If you have numbers on your laptop keyboard (as a rule, this happens on them) instead of letters, it’s okay - see below detailed description how to fix this situation.

The problem occurs on keyboards without a dedicated numeric keypad (which is located on the right side on “large” keyboards), but with the ability to make some of the letter keys possible to quickly type numbers (for example, this is provided on HP laptops).

3. After rebooting, restore the system from the last restore point when the keyboard worked normally. For information on how to restore the system and perform a rollback, read our question about Windows recovery from restore points.

4. If the rollback does not help, reinstall Windows.

The keyboard on the laptop does not work due to oxidation of the cable wires.

If you have children at home, then it makes sense to check for unnecessary items, in the connector or in the system unit (motherboard). I once witnessed a situation where there was paper or chewing gum in the USB port, and therefore the keyboard stopped working.

It is possible that the keyboard has already done its job. To check if it works for you, you can go to your neighbors and ask them to connect your keyboard to their computer. If the keyboard works, then there is something wrong with your computer. You may have a spare keyboard, then connect it to your computer.

If the keyboard only partially prints, you may be unable to type numbers that are on the right side of the keyboard. If so, then press the "Num Lock" button.

By the way, when you are sitting at home, working on a laptop and decide to go outside with it in winter, then turn it off 15 minutes before going out.

If everything is in order with the keyboard cable, wipe its contacts with an ear swab moistened with alcohol, or use a regular eraser. After cleaning, insert the keyboard cable back and test.

2.3. Microcontroller failure or liquid spilled on laptop

If the reason for the laptop keyboard not working is a burnt out microcontroller or spilled liquid, in this case no services service center you can't get by. It is impossible to thoroughly determine which hardware components of the laptop are faulty and solder them at home (of course, if you are not a specialist).

When liquid is spilled on a laptop, if it gets on the board, over time this leads to oxidation of the contacts. As a result, the keyboard completely fails. If you accidentally spill liquid on your laptop, immediately turn it off, remove the battery, and dry it with a hairdryer on a gentle hair-drying setting. If your hair dryer model has a cold air button, use only cold air. This is necessary in order to, if not prevent, then at least slow down the process of oxidation of contacts, microcircuits and boards.
