The second tab opens, the keyboard does not work. Now you need to unscrew all the fasteners: that is, the screws. Driver installation using DriverPack Solution.

Often, we run into computer problems and immediately run to service center... But sometimes, we do not assume that these problems can be fixed by ourselves. First, let's figure out the reasons why the keypad stopped working.
There can be many reasons for a non-working keyboard.

Broken computer keyboard

Now it's worth dealing with computer breakdown... What to do if the keyboard does not work on the computer? As with a laptop, hardware or software glitch... At first, you can try to simply restart your computer. Maybe this will help. Further, you can through the system on a computer using a mouse:

Through the "Start" go to the "Control Panel"
Here we find the "Device Manager" and if the keyboard does not work, it will be indicated by a yellow circle with a black exclamation mark.
Then we press "Action" and "Delete".
After confirming the action, we perform the "Equipment Installation".
After that, the search for devices will be performed and perhaps the keyboard will be found.

These steps will help resolve the issue if the computer does not see the keyboard. Otherwise, you will have to reinstall the operating system.

Reinstalling equipment is one of the methods to solve the problem

Other problems may be related to the fact that the keys do not work, you enter the wrong characters, or the combinations do not work. If the keyboard doesn't respond to taps, it might be dirty and just need to be cleaned. Sometimes the keyboard won't print for other reasons:

Faulty usb connector
Disabled keyboard support in BIOS

BIOS mode

If stopped working usb ports on your computer, you can try restarting your computer. If this does not help, you need to turn to the "Device Manager". We go to "Start", select "Control Panel", then click "Device Manager". Here we select "Action" and "Update hardware configuration". The following line should appear in the list below: “ USB controllers". Next, we check the work.

If the keyboard does not work during boot, you need to turn to BIOS mode. In this case, we need to check whether keypad support is enabled. We already know how to enter BIOS by selecting the desired key combination. In the menu of this mode we find the USB Controller and if the opposite is Disabled, set Enabled. After that, everything will work.

In BIOS, you can disable the keyboard

If the keyboard on the computer stops working, and all the above methods did not help to solve the problem, it remains to contact the professionals in the service center.

Now you know what to do if the keyboard does not work on your computer.

Have you ever had a situation when you, while working at a computer, suddenly noticed that the keyboard refuses to type? It doesn't matter if you text to social networks or you are publishing the most important work in your life: your thesis, master's, or much more promising professorship. You are wondering why the keyboard on the computer does not work. You reboot the operating system in the hope that everything will fix itself, but no. The keyboard remains unresponsive as before. You start to panic. What to do? Call the master or buy 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 most often found in our time. USB keyboards are plug-and-play, so the connection is the most common problem. As soon as the keyboard stops responding, the first step is to unplug it and plug it back into the USB port of your computer device. Perhaps the contacts have simply moved away. This usually fixes the problem. But it also happens that the breakdown is not in the keyboard itself. If these actions did not lead to a positive result, it is likely that the port itself in the computer has broken. Try connecting your device to another device, or at least to a different USB port on your PC. By doing these steps, you can already discard some of the guesses about why the keyboard on the computer is not working. Windows XP, 7, Linux set up device connection settings in different ways. There is a chance 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 the installation of drivers. The keyboard connector has 6 pins for connection. It so happens that if the connector is ineptly connected to the computer port, one of the contacts may bend. It needs to be aligned for the keyboard to work. If the keyboard stopped working while working on it with the PC turned on, be sure: the problem is in the operating system or software. Perhaps some process is slowing down her work. The main difference between a PS / 2 computer keyboard and USB is that if the device fails, you must restart the computer to make it work again. After all, this is not a plug-and-play technology.
A wireless keyboard is a modern type of input device, but this does not mean that it is flawless. It can also refuse to work like other types of devices. You can think for a long time why it doesn’t work. wireless keyboard on the computer, but the main breakdowns and problems occur most often in the case when something is blocking the USB receiver. In this case, you need to clear the computer desk of unnecessary things and see if it works now. Basically, the wireless keyboard is the same USB peripheral, with the only slight difference: there are no wires whatsoever. In this regard, it is necessary first of all to check the blocking of the signal. If there are no changes, then you need to follow the steps described in the USB point of the computer keyboard.

Troubleshooting the problem through the BIOS

You have performed the steps to mechanically fix the problem, but unfortunately it did not help. Panic hits you. Why isn't the keyboard working on my computer? Windows 7 must first be restarted. The problem may be resolved by itself.
Try pressing the Esc button a few times to see if the display autostart menu appears. If there is no response from the program, it is necessary 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 must 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 reboot the operating system.
If, after the steps taken, you still have not solved the problem and ask yourself why the keyboard does not work on the computer, then you need to reinstall the keyboard software in the device manager.

Reinstalling and Configuring Keyboard Software

In the control panel of any operating system in the "Start" menu there is an item "Hardware and Sound", under which there is a view of devices and printers. It is this section that we need. Clicking in the window right click mouse, you must select "Device Manager". Do not forget that you must have administrator rights, otherwise you will not be able to change the settings hidden devices... So, in the new open window we are looking for the required Keyboards item and are trying to solve the problem of why the keyboard does not work on the computer. Windows 7, 8, XP differ slightly in their interface, so the path to the settings menu may differ slightly. Calling the object control panel, you must select the item to reinstall and update the hardware and driver configuration. After restarting the computer, the hardware should work correctly.

The problem of pressing multiple characters with one key on the keyboard

Sometimes, while typing from the keyboard, a situation arises when keys stick and print several characters at once. And the problem is not that you are pressing the keys for too long. The whole point is in the keyboard response settings. To change these parameters, you must manually enter the word "keyboard" in the search bar in the start menu. A new window will appear in front of your eyes, when you open it, you should correctly adjust the delay rate for entering a repeated character. From now on, you will not worry about why the keyboard on the computer does not work correctly.

1 way to fix keyboard inoperability outside the operating system

There are often situations of keyboard failure due to incompatibility of drivers on the operating system. Exists different versions Windows: 32 and 64 bit. How are they different and why do they need different drivers? The main difference in handling different volumes random access memory... That is why it is necessary to install Various types drivers so that at the most inopportune moment you do not panic why the keyboard on the computer does not work. Windows 8, 7, XP, Linux require different types of installation software... But to find out if this is the real cause of the problem, you need to restart your computer and see, pressing the NumLock and CapsLock keyboard keys, check their functionality using the lights up.

2 way to troubleshoot keyboard issues via CMOS

Another way to test the keyboard's functionality outside the operating system is to go to CMOS settings and try the keyboard in safe mode. Sometimes the operating system crashes, safe mode will allow you to fix this breakdown. If the CapsLock and NumLock keys fail, go to the first method.

Computer device beeps when you type with the keyboard: solutions

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

In the appeared results of the control panel there is an item to change them. You need to follow this link, uncheck the Sticky Keys checkbox next to the “Simplify Typing” item and go to their settings. In the new window that opens, uncheck the box next to Sticky Keys when you press the Shift key five times. We save the results by clicking on the OK button, after which the old keyboard settings window opens automatically. In it, we uncheck the box next to the sounding point of the switches by clicking on Num lock button for 5 seconds. After saving the settings, the computer device will no longer beep meticulously.

The numeric keypad refuses to work

Some users, when buying a peripheral device, sometimes wonder why the numbers on the keyboard on the right do not work. On a computer, this situation happens quite often, especially on the Ubuntu operating system. What to do in this case? Try just pressing the two keys combination: Shift + Num Lock. Most often it helps. There is a chance that with numeric keypad mouse control is configured. To turn it off in the operating room Windows system, you must press the Alt + Shift + Num Lock key combination. There is another more complicated path to go with optical mouse settings. But why make life difficult for yourself when pressing a keyboard shortcut can fix the whole problem?

Why the keyboard does not work on the computer when you turn it on: solution

To solve this problem, you need to follow these steps:

Check the connection itself. It doesn't matter what type of keyboard: USB, wireless or PS / 2. If the problem is the connection or loss of signal, the keyboard will not work.
If everything is ok 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 the "Control Panel".
If it is possible to connect the keyboard to another computer device, check its functionality on it. In each operating system, program settings are found in different paths. You need 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 arguably the most complex system to configure software changes. But you don't need a lot of knowledge to change keyboard settings. You must follow the instructions carefully, and then your peripheral device will work again as quickly as before.

Possible reasons why some keys on the keyboard are not working

There are times 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 owner of the computer did it himself, because he knows where the problems with the peripheral device come 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 more often it happens that certain buttons stop working. Then it is necessary to disassemble and manually clean the keyboard, and if it has already oxidized, then completely change it. After all, there is little chance that it will now work as before.

Note to users

Now you know possible reasons breakdown of a computer keyboard. Some users will be new to know that any operating system will automatically install and screen keyboard... In the event of a peripheral device failure, it will definitely help you.

Of course, this is not the most common situation, but it still happens at times: the user turns on the computer, the boot is successful, and then it turns out 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 can handle it on your own.

The simplest and most common reason for keyboard failure, which is eliminated in just a couple of seconds, is the PS / 2 plug, by some accident, fell out of the socket. Perhaps an accident of this kind has four legs, a tail, and a cheerful disposition.

Maybe the keyboard cord was pulled out while cleaning. In short, the first thing to do is to check the position of the plug in the socket, remove and insert it back, and then, if the situation remains unchanged, restart the computer.

However, other cases should not be ruled out - for example, a virus attack. Run anti-virus scan can be done with mouse clicks. If it 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 does not help, then there is no choice, the next step is testing with professional equipment.

Needless to say, a wireless keyboard is a handy invention, but it has one drawback common to all wireless gadgets: it needs to be charged. If you forgot to charge your keyboard in time, it's no surprise that it refuses to work.

A new wireless keyboard that has not yet worked requires its own driver to be installed. Usually, the computer itself finds the required driver in memory, or a driver disk is included with the device.

But sometimes in automatic mode the driver is not installed, and then you have to search and install manually.

The same is done if the driver for some reason has been removed - "flew", as experts say.

The USB keyboard differs from the usual one only in the connection connector - it is not hard to guess that this 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 with special equipment.

However, another option is possible - change BIOS settings... To enter the BIOS, you need to start the boot and press the corresponding key, most often 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, i.e. included. After that, exit the BIOS, remembering 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 hardly used by most users.

If you still have it, and suddenly there is a 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.

The failure of half of the keys is most typical for the so-called multimedia keyboard, on which multimedia adjustments (sound, brightness, color rendition, etc.) are implemented in the form of push-button control.

This media part sometimes crashes after booting due to the media key switching service being disabled. This can be caused by a power surge, hardware failure, or other disruption to your computer.

This problem is very easy to fix. Necessary:

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 drop-down 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 "Service Restart" button;

Click "Apply" and "OK".

After that, in case of a failure, the multimedia buttons will start automatically.

Fortunately, at the moment, the keyboard is such a popular device that you can even buy it in a regular supermarket, not to mention specialized stores. Despite the simplicity of this gadget, problems and malfunctions can arise with it. One of the more well-known problems goes 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 you can deal with the problem. It should also be added that in this case we will focus on computer keyboard, and about the keyboard for the laptop I will sit next time, since there is a very big difference between them.

Causes of problems and solutions

Where should you start? First of all, you shouldn't panic. Yes, that's right, because in 90% of cases your problem is very easy to solve.

If you have a pet that loves to climb everywhere, I recommend that you take a look at the back wall system unit... It is possible that a cat passing by touched the keyboard plug and it simply fell out of the nest.

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 restarting the PC, the device starts working in 90% of cases.

If you are using a PS / 2 keyboard, take a close look at the connector itself. The fact is that his legs could be bent, which must be aligned, otherwise he will not work. For this, tweezers (ideally) or something sharp, such as knitting needles, will work 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 device is working properly. Ideally, it is better to check its performance on another PC or laptop.

It is theoretically possible that the keyboard has ordered a long life, in other words, has fallen into disrepair. However, in practice, this happens very rarely, moreover, often only one or several buttons fail. It's easy to check - connect the device to another computer or laptop.

One of the funniest problems with entering numbers - users complain that right part the gadget where the numbers are located does not work. In fact, it connects on demand with the Num Lock button, which is located above the numbers. This is done so that you do not 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, 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 pressing. In this case, it is sufficient to remove only one key, which, fortunately, is very easy to do.

If you have an expensive enough keyboard with many additional buttons you probably need to install separate drivers. Without them, the keyboard can and will work, but apart from individual buttons. It is necessary to 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 that is responsible for its operation. It may have been damaged. This problem can be solved in two ways: either we update the drivers to latest version, or a few days ago, when the keyboard worked.

If you just purchased a computer and have never used it before, try entering BIOS - perhaps keyboard support is disabled. In the BIOS menu, you need to find an item called USB Keyboard Support and translate it from Disabled to Enabled.

In case you are using wireless device(keyboard), which runs on batteries, do not forget to charge it. It probably just ran out of power, and therefore stopped working.

Also, users often complain that the keyboard does not work in games or programs. Fortunately, in most cases, fixing 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, let me 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 she will have to spend money on buying a new one, because the repair this device usually unnecessarily expensive.

Instructions

The main reasons for such a malfunction lie in a hardware failure or software error... Checking the hardware version is very simple - check the plug on your keyboard and the connection socket. If everything looks okay, replace the keyboard with a good one and restart the computer. In case of further inability to use this device, you should check the version of the software malfunction.

First, try to reboot the machine. Perhaps, operating system localizes and fixes a software glitch. Try reinstalling your keyboard. To do this, in the "System Properties" window, "System" "Control Panel", find the "Hardware" tab. Click the Device Manager button. In the "Device Manager" window, highlight the "Keyboard" item and delete it, close the "Device Manager". Then enter the item "Hardware Installation" and run the "Installation Wizard". Click the Next button and wait while the installer detects the keyboard. The OS will inform about the detection and functioning of the keyboard by turning on the Num Lock indicator light. If the program displays a message about the completion of the installation of new devices and prompts you to reboot, then click the "No" button, since the keyboard is already functional. Also click the Finish button in the Add New Hardware Wizard and exit the System Properties menu.

One of the options for a malfunction may be that the operating system does not detect the required driver. To reinstall the driver, go to the website of your keyboard manufacturer, select the model you need, download the archive and unpack it. As a rule, such drivers are equipped with their own installation program, and then you should just run the file. If there is none, then you will have to launch the "Device Manager", select the "Update driver" command and specify in the mode manual search path to the directory where the unpacked driver is located. The computer must be restarted after installation.

Often, a non-working keyboard is the result of a virus program that has settled in your machine. A typical sign of this is the failure of the mouse, as well as the touchpad. Check the system with antivirus software... It's best not to rely on free utilities that promise instant success and heal your computer. Use proven and well-known antiviruses. The chances of success with this kind of collateral are much higher.

A very real reason for a keyboard failure can also be a lack of BIOS connection. This failure is especially common on machines with built-in keyboards. Correcting the situation can be quite simple. Turn on BIOS while the computer boots. Find the tab with a list of input and output devices. Select USB Controller and enable Enabled. Enable the same mode for the USB Keyboard Setup item. Exit BIOS with confirmation to save new settings. In the event that none of the above helped you, then contact the service center.
