The keyboard is the main tool when working on a computer, without which work is almost impossible. Of course, you can enter information using the mouse and the 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 everything possible reasons this fault.
The keyboard is a fairly simple device and usually works flawlessly. However, there are times when the keyboard light is on but nothing is printed.
Why the keyboard does not work: reasons
There are two types of reasons why a computer keyboard may not work:
- Mechanical (cable breakage, moisture ingress, excessive contamination of the keyboard, violation of the integrity of the connection ports, and so on).
- Software (failures in the software, wrong settings BIOS, incorrect keyboard drivers, etc.).
Consider all the main reasons why the keyboard does not work and troubleshooting methods.
Keyboard cable or port failure
The first step is to assess the physical condition of the keyboard.
Look at the button indications cap lock and Num Lock. Most likely, if they work, then physically everything should be in order with the keyboard.
Inspect the keyboard cable with your eyes. It may be pinched or cut. For example, many pet owners have pets that gnaw through cables.
Also, visually check the keyboard connection port for breaks or bends. There are two types of keyboard connection ports - USB and PS / 2.
It often happens that in the PS / 2 port, when trying to connect to a computer, people break off the tip of the core and the keyboard does not connect.
If outwardly USB cable If the keyboard and connection port look good, try plugging the keyboard into another USB port on your computer. Perhaps the port on the computer itself is corrupted. If the keyboard works in another port on the computer, then you have a problem with the USB port. Usually there are several of them on the computer and you can just 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 PS/2 port on your computer, you'll have to find another such keyboard.
Liquid spilled or dirty on the keyboard
A flooded keyboard is a headache for all IT people 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, visually and by smell, it is easy to determine that liquid has been spilled on the keyboard. Take a close look at 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 assemble it back. With a high degree of probability, the keyboard will work.
Earlier, 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 has an item on enabling and disabling USB support keyboards on a computer.
Additionally, in this way you can check the health 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 the keyboard until the window BIOS settings.
- In the BIOS settings, find the USB Keyboard Support or Legacy USB menu.
- Make sure the setting is in the Enable state. If Disable is written, then switch to Enable.
You can at the same time set the rest of the USB-related BIOS settings to the Enable state. Perhaps you will earn ports on the front panel of the computer case that once stopped working.
Software or driver failure
Keyboards with older PS/2 connectors are more prone to software crashes. However, there are still quite a lot of such keyboards in use, although manufacturers have almost stopped producing them.
To solve the problem with the keyboard not working due to software, you need to turn on the computer and log in to the desktop. Since the keyboard has stopped working and does not print, and a password may be set on the account, you will need to use the on-screen keyboard and type the password with the mouse.
Now that you are on the desktop of your computer, you need to get into the Device Manager.
In Windows 8 and Windows 10, to do this, right-click on the button Start and choose device Manager.
In Windows 7 left click on the button Start. Next, right click on the word Computer and choose Computer management — device Manager.
Device Manager displays information about all devices on your computer. Expand the Keyboard branch. If an orange question mark is lit next to your keyboard, then the device is not installed correctly in the system.
Right click on the keyboard and select Delete.
After that click Action — Update hardware configuration.
The computer will re-interrogate all devices and install the keyboard correctly.
Factory defect or keyboard life has come to an end
Any technology tends to break down and fail. If the keyboard was purchased relatively recently, then you may have encountered a factory defect. In this case, you can contact the keyboard manufacturer's support service and count on a replacement device.
The fact is that many manufacturers value their reputation and, without entering into a long debate with the buyer, they immediately send a brand new keyboard by mail.
If the keyboard has been with you for more than a year, then most likely it has failed due to the service time and you should buy a new one.
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 when loading the required 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 your 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 function perfectly).
Step by step steps to fix the problem:
- Start button –> then Settings –> after Control Panel –> System;
- click on System Properties -> then Hardware -> Device Manager;
- in the window called "Device Manager" highlight the large yellow circle with a black exclamation mark;
- select the menu item Action –> then Delete;
- in the window "Confirm device removal" you need to authorize the removal of the keyboard by pressing OK;
- close Device Manager;
- in the window with the name System Properties on the Hardware tab, you need to click the Hardware Installation button;
- in the window that opens called Hardware Installation Wizard, click Next;
- after a short search for hardware, your keyboard should be “found” (the Num Lock indicator will turn on);
- after these steps, the Change system settings window should appear with the message text "Installation of new devices is completed."
- the last action is to click Finish in the Hardware Installation Wizard window.
What should be the actions if several or one button stops working
If some keys on the keyboard have stopped working, it is possible that the keyboard driver needs to be updated, or is completely missing.
If you purchased a software disc with 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, find the keyboard you are using and double-click on it.
- Then on the Driver tab, click Update and follow all the instructions.
- Answer yes to the pop-up suggestion to restart the computer.

If the receiver is strongly attached to the cable, you can position it so that it is flush 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 checked software The keyboard indicates the presence of a charge.
How to “cure” a flooded device at home?

4. If the rollback did 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 extra items in the connector or in the system unit itself (motherboard). Once I witnessed a situation when there was paper or chewing gum in the USB port, and therefore the keyboard stopped working.
- It is possible that the keyboard has already worked its way. To check if you have it working, you can go to your neighbors with a request to connect your keyboard to their computer. If the keyboard works, then something is related to your computer. Perhaps you have a spare keyboard, then connect it to your computer.
- If the keyboard does not print only partially, you may not be able to type the numbers that are on the right side of the keyboard. If so, then press the "Num Lock" button.

2.3. Failure of the microcontroller or liquid spilled on the laptop
If the cause of the non-working laptop keyboard is a burnt microcontroller or spilled liquid, in this case you cannot do without the services of a service center. It is impossible to thoroughly determine which hardware components of a laptop are out of order and solder them at home (of course, if you are not an expert).
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 is completely out of order. If you accidentally spill liquid on your laptop, turn it off immediately, remove the battery, and dry it with a hair dryer on a gentle setting to dry your hair. If your hair dryer has a cold air button, use cold air only. This is necessary in order to, if not prevent, then at least slow down the process of oxidation of contacts, microcircuits and boards.

In this article, we have to deal with a rather important question: for what reasons can the keyboard stop typing? This phenomenon is actually not so rare. But do not be afraid ahead of time. Problems with I / O devices can be solved without any problems. And only in some situations you have to seriously try to restore the performance 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 is not very common, but it also takes place. Especially often owners of old computers face this problem. For laptops, this alignment is relevant only if we are talking about a separately connected keyboard. What is it about in this case? Why does the keyboard refuse to type? The problem may be a malfunction of the connector for connecting the equipment. Sometimes it gets damaged or broken. The keyboard in this situation simply cannot be connected. If using an older model personal computer with a PS / 2 socket, it would be better to change the equipment to USB. You can also try connecting the device to a different connector. You can also try to fix 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 causes of 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 step is to try to reinstall or update the drivers for it. As a rule, multifunctional keyboards come with a disc with the corresponding software. After that, you need to restart your computer. If the reason was precisely in the drivers, then after carrying out 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 it is not as simple as it might seem at first glance. A personal computer is a very complex device that can bring various surprises. Fixing them isn't always easy. For what other reasons can the keyboard refuse to print?
blockage
Why doesn't the keyboard work? Sooner or later, this question begins to worry many users. This is especially true for those who do not pay due attention to the care of the computer and its components. What to do if the keyboard does not print some letters? If we are talking about a device that had previously worked properly for more than one month, then we can advise you to clean the keyboard. After all, the keyboard is such a device that can easily become clogged. There may be dust, crumbs and food leftovers between the buttons. This applies to both laptops and desktops. 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 needed. It is also recommended not to eat in front of the monitor. This will reduce the chance 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 type. 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 keyboard from the laptop 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 after cleaning will work in full force.
Reinstallation
These are not all scenarios. In some cases, it happens that the keyboard prints the wrong letters. Finding an explanation for everything that happens is sometimes very difficult. After all, the device actually works, but not quite the way it should. The reason why the keyboard prints the wrong characters is one - the wrong assembly of the device. If you disassemble the keyboard, you will notice that each key has its own special mechanism. The computer receives a signal from a certain key and prints a certain character. To ensure the convenience of the user, these mechanisms are signed in the form of buttons on the keyboard. If these mechanisms are reversed, then it seems that the device prints the wrong characters. There can be only one way out of this situation - to assemble the keyboard correctly. To do this, you need to place the mechanisms that are under each key in the right order. Performing this procedure on your own is very problematic. It is best to take the device to a specialized service center. If you do not want to once again think about why the keyboard does not print, then you need to wash and wipe this component from time to time. The problem with incorrect placement of buttons often happens after cleaning the keyboard yourself. This is not the most dangerous problem, albeit a little unpleasant.
Incorrect assembly
What to do if the buttons on the keyboard do not work for you? First, don't panic. Try to analyze your recent activities 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 their own, it is recommended to immediately carry it to a service center. The reason is the incorrect assembly of the input device. The user most likely tried to assemble the keyboard, but somewhere some important contact came off. This phenomenon occurs quite often. It is quite possible to fix the problem on your own. However, users point out that the keyboard in inept hands will not work in any way, and may even be completely broken. Craftsmen usually manage 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 a new device, then the scenarios listed above may well be the reason for the failure of this component to work. However, what 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 factory defect. In this case, only a complete replacement of the keyboard will help. You must contact the store where you purchased the device. You can exchange it there. Otherwise, you just have to buy a new gadget.
Incompatibility
What can be done 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 independently. If the keyboard refuses to print, then the problem may be that the device is not compatible with the operating system. This kind of problem has appeared relatively recently. It is most often encountered by users working with the Windows 10 operating system. Older keyboard models simply do not work with this operating system. This problem is not observed on laptops. In addition, the keyboard also has its own minimum requirements. You should pay special attention to them. Ultimately, you will either have to change the device or reinstall the operating system that will be compatible with the gadget.
Viruses
Keys on the keyboard refuse to work? Is the device not working at all? If all the situations described above do not fit, then we can consider the last, rarest scenario - infection of the operating system. Malicious objects and viruses are the main enemies of the stable operation of personal computers. They are able to influence not only the software, but also the connected devices. So, 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 puts down several letters / numbers at a single press. There can be two ways out of this situation: it is reinstalling the operating system from scratch and treating the computer from the corresponding infection. If you choose the first solution to 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 the computer. In this way, you are guaranteed to be able to get rid of the virus.
Without a keyboard, we cannot imagine the full operation of a computer, because it is one of the main components of a PC. If the keyboard is broken, then you need to find the source of damage.

Then move the viruses to quarantine or completely delete and restart the computer. The keyboard should work.
Drivers
Often faced with the fact that the keyboard does not work on a laptop, and the reason is outdated drivers. This is the simplest case that every user can handle. You need to update the driver and restart the computer and the keyboard works again.
physical problems.
This problem is very serious as it can cover a wide range of causes. The point may be in the contamination of the contacts that prevent the plug from contacting the computer, or the buttons and microcircuits may be damaged, which will only need to be changed in diagnostic centers. Broken contacts can also be the cause. If the user was not careful and pulled the cord, then the contact and socket may well be broken.
How to determine why the keyboard has stopped working?
There are three most simple ways check it out! Let's analyze each in detail.
Check contacts
Perhaps they just moved away from the computer. Especially if there is a pet, then it could catch the cord. This is the most common problem. Just stick a stronger plug and everything should work. If it does not help, then try to stick out and put the cord back in, as there are failures in the computer. If this did not help, then we move on to the second reason, which will help solve this issue.
Check your computer for viruses
Try checking your PC for malware. Use only licensed versions of antiviruses, such as: kasperky, avast, doctor web. They can definitely help in getting rid of viruses. Spend deep cleaning the entire computer, after which all viruses must be moved to quarantine and removed. After restarting the computer, the keyboard should work. But viruses are not always to blame.
Each driver sooner or later becomes obsolete, which means it needs to be updated. There are two ways to update the driver: download a new one from the Internet, which will be convenient for users who have an Internet connection.
And the second way is to install the driver from the disk that came with the computer when you bought it. The driver is installed as a normal game, after which it requires a restart of the computer. The keyboard should work. Follow the following advice, it is useful for every PC user: download programs from the Internet Driver Pack Solution or DriverDoc. These programs will be able to automatically install drivers for you when you connect to the Internet. To check for drivers on your computer, follow these steps:
- Go to start menu.
- Click on the "Computer" tab with the right mouse button.
- Go to the "Management" tab, which is protected by the administrative rights of the computer.
- Go to device manager.
- Click on the "Keyboard" tab, then right-click on the keyboard.
- Click LMB on "Update driver". With the help of these programs, it will automatically be updated to latest version.
After that, the keyboard should work. Repeat this action every one to two months.
What to do if the keyboard does not work on a computer with windows 10?
In this case, there are two main problems for which the keyboard may not work.
- This is a problem in the operating room itself. Windows system 10.
- A problem related to defects in your computer or laptop.
Without a keyboard, you are unlikely to be able to do anything, so use the temporarily on-screen option. Go to "Settings", go to " Special abilities and select the Keyboard tab. Move the circle to the "On-Screen Keyboard" so that "ON" lights up.
Check the plugs and connectors carefully, they may be damaged. Try plugging the USB plug into a different port on the back of the computer, that might be the problem.
The cable may be damaged in the laptop, so do not try to fix the breakdown yourself. It is better to take the laptop to a service where specialists can look at it.
OS configuration
In order for you to finally find out the problem in the computer or keyboard, you need to go into the BIOS, since it does not interact with the operating system in any way, but is involved with motherboard. If everything works in your BIOS, then the problem is already in the operating system. If the keyboard and mouse do not work already during the installation of windows, then the problem is in Windows 10, not devices. And if the keyboard does not respond in the program, then there is already a problem either in it or in the computer itself. For reliability, you can ask your friends for a keyboard to try it out for yourself. To resolve this issue, try:
- Restart BIOS several times.
- Go to the “Control Panel”, then to “Windows Troubleshooting” (in particular, the item “Keyboard” or “Device Hardware”). Uninstall the keyboard in device manager). In the "action" menu, click on the "Update computer configuration" icon. Everything must work.
- Make sure you have the Num Lock key turned on when entering your password. You can determine this by the indicator on the keyboard (If it glows, then the key is on).
Clean off dirt/dust
It is possible that the sockets into which the plugs are stuck are simply clogged with dust, therefore preventing the contacts from interacting. To do this, simply disassemble the computer, it is advisable to work with soft brushes. You can use a vacuum cleaner that has a blowing function. In most cases, this method is very effective. Dirt do not try to pick something, take a special wet wipe, which is sold in any computer store. Use it to remove dirt.
What to do if the keyboard does not work in assassins creed origins?

Wireless keyboard and mouse not working
If the wireless keyboard does not work, check the battery first and replace it if necessary. Do the same with the mouse. But if after that the keyboard and mouse do not work and you are sure that the battery is full, then find working devices and go to the control panel, go to "Devices and Printers". Next, right-click and click "Connect device", well, or confirm the action. Don't forget to restart your computer.
First of all, check the plug in the socket, whether the keyboard is connected correctly. If the computer is outdated, then BIOS version will be old, because of this, the device may not recognize USB devices. Go to the "USB Keyboard Support" section and look at the inscription. If it says "Disabled", then the device is disabled, change it to "Enabled" and everything will be connected.
If you have several PCs in the house, then try the keyboard on another computer in the BIOS program. If it works, then the problem is with your computer. Some programmers remove the battery from the motherboard for a few minutes, then the BIOS is reset to factory settings, but an inexperienced PC user is not recommended to do this.
What to do if the buttons on the keyboard do not work?
Try to carefully remove the buttons and clean them of debris, as they may not work for this reason. The keyboard buttons are connected by thin microcircuits, which can be easily damaged. Viruses are unlikely to be able to harm here, so if nothing helped after cleaning, it is better to replace the keyboard. There is an option to try a different keyboard on your computer. If it works, then the problem is in your previous device. The same can be said about the number buttons. Try to be more careful when disassembling the keyboard.
If nothing helped, but you urgently need to print the text.
If this happens, then use the on-screen keyboard. Go to the "Computer" menu, then go to " local disk C", then go to the "Windows" folder, select "System 32/64", depending on your computer and open the "osk" file. This will be screen keyboard. You can type with the mouse.

There may be several reasons for this: spilled liquid, mechanical impact (strong impact), connection problems, etc. Of course, you can also use the screen version, but this causes huge difficulties in the work. The situation may not be so critical if a few letters on the keyboard do not work, but if it refuses to work completely, the user will not even be able to boot the OS on a subsequent reboot. In this situation, you should not be upset, because this input device can be repaired even on your own.
Of course, the least troublesome option would be to completely replace the keyboard. But this input device for a laptop costs quite a lot. And given that a gaming model could be used on a stationary computer, the costs will be tangible. Therefore, in order not to spend extra money, we will understand the issues of self-repair and prevention of the keyboard.
Connection issues
In a keyboard for a personal computer, it is much easier to verify that the connection is working than for a laptop. First, disconnect it from the PC and see if there is any mechanical damage on the connector. And if only tracks can be damaged in a USB connector (although this case is extremely rare), then legs can be broken in PS / 2. Look at the screenshot and compare with the real connector the placement of the pins.
If everything is in order with the connector, also check the input in the system unit for damage (if it concerns USB, try connecting it to a different connector on the motherboard).
Also, if you are connecting a model with a USB output for the first time and it refuses to work, you need to check the correctness of the BIOS settings (this requires another keyboard with a PS / 2 connector):
- Enter the BIOS menu by pressing the Del button;
- Look for USB string keyboard support;
- If it is set to Disable, it must be changed to Enable.
If the above actions did not bring the desired result, check the connection cord for mechanical damage.
As for the laptop keyboard, the cable to the motherboard may be loose or broken. But each laptop has its own characteristics, and each model is parsed differently. To check this, you need to use the special instructions for parsing and try to reconnect it to the motherboard.
Keyboard repair
Before reading this manual, remember that if the product has not expired after the work done, you will lose the warranty. Therefore, in this case, it is better to contact an authorized service center.
The reason for the failure of the letters or the entire keyboard may be spilled liquid, the appearance of dust and other debris on the tracks, or the failure of the tracks. If it comes to moisture and dust, disassemble the keyboard and carefully remove debris and moisture, after which it should work. As for the damaged tracks, in this situation it is necessary to draw new ones.
Important! Before you start work, you should have available: conductive glue, tester, tweezers (thin hook).
First of all, you need to get to the plastic boards. And if in a keyboard for a stationary computer you only need to unscrew the bolts, then with a keyboard from a laptop, things are much more complicated. Let's describe in detail the analysis of the keyboard for a laptop with screenshots:
1. Remove the keyboard from the laptop (for each model, this step is performed differently (individually) see how to disassemble an Acer laptop).
2. Using the hook, carefully detach the buttons.
3. Remove the lifts from the base.
4. Remove the protective surface and carefully remove the polyethylene board.
5. Next, check the available tracks with a tester. If the resistance is very close to zero, then it is working, otherwise it must be redrawn. To do this, apply a thin layer (on top) of electrically conductive adhesive and allow it to dry.
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, problems and malfunctions can occur with it. One of the most well-known problems goes something like this: "the keyboard has stopped working." it just stopped and that's it. Today I will talk about why this can happen and how you can deal with problems. It should also be added that in this case we are talking about computer keyboard, and next time I will talk about a laptop keyboard, since there is a very big difference between them.
Causes of problems and solutions
Where to start? First of all, don'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 you take a look at the back wall system block. It is possible that a cat passing by touched the keyboard plug and it just fell out of the socket.
- Next possible variant- a glitch that occurred in the operating system. For such cases, there are two solutions to the problem. Firstly, unplug the plug for a few seconds and plug it back in, and secondly, you can restart your computer if the first option did not help. After rebooting the PC, the device starts working in 90% of cases.
- If you are using a PS / 2 keyboard, then carefully inspect the connector itself. The fact is that his legs could be bent, which must be aligned, otherwise he will not work. To do this, you will need tweezers (ideally) or something sharp like knitting needles.
- Most modern keyboards (as well as) connect to a PC based on a modern USB system. It is recommended to change the USB port and check if the device works. Ideally, it is better to check its performance on another PC or laptop.
- Theoretically, it is possible that the keyboard died a long time, in other words, it fell into disrepair. However, in practice this happens very rarely, moreover, often only one or several buttons fail. Checking this is easy - connect the device to another computer or laptop.
- One of the funniest problems associated with the introduction of numbers - users complain that the right side of the gadget, where the numbers are located, does not work. In fact, it connects on 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 that is located inside the case slips. Sometimes various crumbs and other small objects fall on it. To get rid of them, the keyboard must be disassembled and cleaned. By the way, large crumbs can get 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 to do.
- If you have a fairly expensive keyboard with lots of extra buttons, you probably need to install separate drivers. Without them, the keyboard can and will work, but apart from individual buttons. You need to install drivers for the device, which can be found on the official website of the manufacturer.
- By the way, about the drivers. In some cases, a problem arises not with the keyboard itself, but with the driver that is responsible for its operation. It may have been damaged. This problem can be solved in two ways: either update the drivers to the latest version, or a few days ago when the keyboard was working.
- If you just purchased a computer and have never used it yet, try going into BIOS - perhaps keyboard support is disabled. In the BIOS menu, you need to find an item called USB Keyboard Support and transfer it from the Disabled to Enabled position.
- In case you are using wireless device(keyboard), which runs on batteries, do not forget to charge it. Probably, it was just discharged, and therefore stopped working.
- And users often complain that the keyboard does not work in games or programs. Fortunately, in most cases, dealing with this problem is easy. The fact is that by default the control is programmed for certain keys, which you can change at your discretion. To do this, you need to go to the game settings. The same fully applies to and.
Finally, I remind you once again that in most cases you can solve the problem with the keyboard yourself. Well, if she still refused to work, then you will have to spend money on buying a new one, because the repair this device usually unreasonably expensive.
