The keyboard is stuck what to do. Launch the keyboard on a Windows PC. Electronic and mechanical filling

Often PC users face a problem when it crashes and does not work wireless keyboard... There are a lot of reasons why this happens, ranging from simple and trivial, to hardware failure. In today's article, we will tell you in detail about all the most common malfunctions of wireless keyboards, as well as consider ways to eliminate breakdowns.

Battery discharged

The first and most commonplace wireless keyboard is a discharged battery. It's no secret that all wireless peripherals are powered by batteries and, of course, need to be charged from time to time. If you don't, then one day the device will not work.

So, if suddenly the keyboard does not function, then first of all you should check the charge level, because exactly how could it be the culprit of the problem. If everything is in order with the batteries, then you should go to the next item.

Disrupted wireless connection

Another very common reason why the wireless keyboard does not work is a malfunction. wireless connection... Wireless peripherals connect to the computer via bluetooth adapter, but it's not enough just to plug its connector on the system unit, you still need to make the connection itself, through the pairing button.

But it also happens that established connection between the keyboard and the computer is lost or torn, for example, due to improper shutdown of the PC. To resume the operation of the wireless keyboard, it will be enough to re-pair via the corresponding button on the periphery itself. It's that simple!

Driver failure

Next reasonwhy the wireless keyboard does not work - driver failure. This is also a fairly common phenomenon, which, unfortunately, occurs at the most unexpected moment, and, alas, this cannot be prevented.

There are actually many reasons why drivers can crash, even the same power surge and an unforeseen restart of the computer can contribute, but now that's not the point.

There are two ways to fix the problem with the drivers - a simple reinstallation or complete removal and a clean install.

In the first case, you just need to reinstall the drivers and restart the computer. In the second case, you will have to perform several additional manipulations.

First you need to go to the "Device Manager". This can be done easily - you need to press right click mouse on the "Start" icon and select the appropriate item from the menu that appears.

Next, in the "Device Manager" we find the "Keyboards" tab and expand it. In the tab that opens, there should be a keyboard, that's what you need to delete. To do this, click on it RMB and select in context menu item "Remove device".

Now, after these simple manipulations, you need to restart your computer and perform a clean installation of the drivers on the keyboard.

Signal problems

Another common problem why the wireless keyboard doesn't work is an unstable Bluetooth signal. You need to carefully check how well the module is installed in the USB port, and also if there are any foreign objects near it that could jam the signal.

Jamming items, as a rule, include Wi-Fi routers, modems, radios, phones with an enabled Wi-Fi module or 3G / 4G connection, an activated Bluetooth module on phones, wireless speakers and stuff like that.

Bluetooth module

The next reason the wireless keyboard stops working is the Bluetooth module. It often happens that the wireless module is accidentally removed from the computer or it loses contact, which stops the power supply. It also happens that users accidentally or by mistake disable a module in the operating system, which also disrupts its operation.

In this case, the problem is fixed very simply - it is enough to reconnect the module to the computer or activate its operation in the system.

But do not forget that there are times when the Bluetooth module completely fails and here, alas, nothing can be helped. But before you write off wireless transmitter, it should be checked for operability on another computer - you never know. If it is not identified there, then you can go to the store for a new module.

Liquid ingress

Prev last reasonwhy the wireless keyboard on the computer does not work - liquid spills on the periphery. In this case, no clarifications are required, since everything is clear to everyone. Many people are faced with the fact that they spill tea, coffee, juice or just water on the keyboard, after which it either starts to work poorly or stops working altogether.

What can be done in such a situation? Well, first, a wet keyboard must be disassembled and left somewhere for a day so that it is completely dry. After that, if something sweet was spilled, then be sure to carefully wipe all the elements, especially the scheme with paths for buttons, with an alcohol napkin. Once this is done, you can assemble the keyboard and try to connect it.

In most cases, everything goes well, and the peripherals continue to function, but there can be sad consequences in the form of refusal to work on individual buttons or blocks, as well as a complete refusal of the entire keyboard to work.

Broken keyboard

And finally, the last reason. Why is the wireless keyboard not working but the mouse working? This is a good question, but the answer to it will be sad for many. If none of the above methods helps in solving the problem, and the peripherals refuse to work, then there is only one thing left - a keyboard breakdown.

In this case, the only solution that will help in resolving the problem is to buy new peripherals.

Keyboard Problems computer easier to solve - there is always a possibility verify the keyboard used on another computer or vice versa - connect it to your PC exactly serviceable... Then act according to the circumstances.

FROM laptop a different situation - the keyboard is built-in, that is, an integral part.

Anyway, first of all try reload device and go to BIOS (usually the key F2 at the time of initialization for laptops, Del or F10 for stationary PCs). It didn't work - chances are high device malfunctionmost likely you will have to contact service center... Before that recommend check contacts - maybe they oxidized or wrung out (relevant for PS / 2) or check cable integrity - he may have received damage (for example, it was pinched).

If you succeeded - therefore, the keyboard serviceable, we are dealing with a software glitch.

In this case, boot the system, it would be better to do this in safe mode without starting the drivers ( F8 while loading). The device is functioning - it means the driver. Start the OS in normal mode, right-click on the icon A computer – Properties.

Find the section Keyboards and delete whatever is in the subsection.

Then reboot computer and check if the keyboard is working. In normal state, the driver should be installed automatically... Here in Dispatcher can be updated or reinstall driver - this option is suitable if there is a designation of unidentified devices with a yellow exclamation mark.

The next option is system rollback to the restore point to the date when the keyboard worked exactly.

For this we go Start/ Control Panel

Run the program here Recovery.

Running system recovery - choose pointto rollback to.

In a more radical way, complete reinstallation operating system.

You can enter characters when the keyboard is not working with screen application.

Start/ Special abilities.

By clicking the cursor on the image of the virtual keys, information will be entered.

This is a temporary measure will simplify search and solution of the problem. For a laptop, another temporary solution would be connection ordinary USB keyboard to any free port.

For more advanced users, you can of course disassemble and verify connection loop. We will not dwell on this in detail in this article.

The numbers on the right don't work

If only the numbers on the right do not work, first of all check if Num lock, some users may forget to enable it.

Above is the normally enabled Num Lock mode illuminated the green LED is on (in rare cases, it may not be).

If the numbers still do not print, check if the Num Lock button actually performs this action. Sometimes this mode includes a combination Num Lock + SHIFT or another.

Also check if your option is not enabled mouse control from the keyboard.

Start\ Control Panel\ Special abilities\ Mouse

There should not be a tick on the item “ Keyboard control«.

F1-f12 keys not working

If a it comes about the owners of laptops, the key is responsible for turning on the function keys Fn.

Some types of PC office devices have a “ Office", You need to check its work. In other cases, it should help reinstallation drivers.

The keyboard is the primary way to enter data into a computer or laptop. With the help of it, you can enter letters and numbers, and with proper skill, you can even do without a mouse, moving around the interface using only buttons. Accordingly, in the event that the keyboard suddenly does not work, the user literally loses his hands. Of course, you can get by with the mouse, but the typing speed and interaction possibilities drop dramatically. So, you need to bring Claudia back to life as soon as possible.

Breakdown reasons

The keyboard is a rather complex device, so it is impossible to say with absolute certainty why the keyboard does not print on the computer. There can be many reasons and all of them need to be considered. And until the device returns to its legal capacity, you can use virtual keyboard from Yandex or Google.

Reasons for Klava's refusal:

Software.
Mechanical.

The first point covers all problems associated with drivers and other software. Under the second, all external damage that could occur during operation falls: a cable break, damage to the plug, and others.

Drivers and software

Most often, the problem lies precisely in software therefore, we must begin with it. Usually, when a new device is connected to a computer, the drivers are automatically downloaded from the Internet and installed. But it also happens that a failure occurs. The solution in this situation is simple - you need to restart the PC or disconnect, and then reconnect the keyboard. This will reactivate the driver search protocol and will most likely download them.

There are some keyboards that will initially not work with operating systemswhich are different from Windows. This also needs to be remembered when connecting an incomplete device, for example, to a Mac.

There are also keyboards that require the installation of additional software on their own to reveal all the functions of the device. This usually applies to expensive models from the gaming segment, in which you can remap keys and customize the backlight. And without special software, the device will work, but not all functions will be active.

An incorrectly configured BIOS can also cause the keyboard to not be recognized. It has a direct shutdown function uSB support keyboard that can be active. As a result, the keyboard does not respond to pressing, although it is fully functional.

To change the settings in the BIOS, you need to hold down one of the keys when turning on the PC or laptop top row Claudia, most often it is DELETE. Yes, it sounds illogical - after all, the keyboard just does not work, but there is no other way to enter BIOS. In such a situation, you will have to use a keyboard with a PS / 2 connector, which was used before USB. You need to understand exactly that this is the problem. Therefore, it is better first to walk on other possible reasons breakage.

Mechanical damage

The software component is not the only reason why the keyboard on the computer does not work. Often the reasons why it is buggy or does not work well are mechanical and external damage... And it's not always the matter of the clave itself. The reason may be the motherboard or the wire.

Cable and plug

The first step is to check the condition of the connector in motherboard... It so happens that for some reason it is he who does not work. It's easy to do - either rearrange the keyboard to a different port, or insert another working device instead. If after this procedure the keyboard worked, then the reason lay precisely in the connector on the motherboard.

If this does not help, then you need to deal with the wire. Usually the problem is not critical, more precisely, the device works and does not work. This means that somewhere inside the cable, the wire is broken and leaves when it moves. Thus, the keyboard does not work, and then it turns on and functions again. This is inconvenient and the connection may be lost forever. In this case, take the device for repair.

Keys and electronics

No matter how many times they say that you can't eat and drink at the keyboard, it doesn't matter the most common cause of device failure is coffee, tea or other liquidwith which she was flooded. With careless use, the clave is poured, and then it can break down and refuse either completely or partially.

It so happens that a whole loop is turned off (that is, a specific row of keys will not work), and it also happens that the problem will affect only a few keys - it all depends on luck. In this situation, there are only two ways to solve the problem - to carry the device for cleaning or to buy a new one.

But you need to understand that cleaning does not give a guaranteed result, which means you need to mentally prepare for the purchase of a new device.

Varieties of keyboards

The range of these gadgets in computer stores is wide, and they differ not only in design and color. Knowing which type of device you are using will help you understand why the keyboard on your computer is not working.

By sight

By the type of connection to a computer, keyboards are:

wired;
wireless.

Devices with a wired interface are connected to system unit via USB port or PS / 2. Wireless is a more modern solution. They run on batteries and are connected via Bluetooth and WiFi.

By design

By design keypads are subdivided into:

mechanical (their principle of operation is based on compression and return to the original position of the key springs, which ensures their high strength and reliability of operation);
semi-mechanical, the difference from the previous ones is the use of rubber elastic elements or similar materials instead of springs;
membrane, in which there are no mechanical moving parts, and a film electrically conductive material is used for the contact pad.

The last of the mentioned types is the most budgetary and compact option, while completely protected from moisture and dirt, since the keys are applied on it in the form of a pattern. This is also its disadvantage: the lack of a tactile "response" makes it difficult to work, including with the help of "blind" typing.

Types of problems and how to fix problems

Good news for a start. In 9 out of 10 cases, problems with the keyboard are solved easily and without contacting the service department. In general, the reasons for the failure of the device can be divided into two types: hardwarewhen it fails the gadget itself or the portto which it is attached, and programmaticwhen a crash occurs while loading drivers. In any case, do not rush to throw away the old one and buy a new manual until you make simple attempts to revive it.

Keyboard does not work when I turn on the computer

It always worked like a clock, but the next time it was turned on, it did not show signs of life - the indicators did not work and pressing the keys did not give a response. Oddly enough, the simplest solution is forgotten at this moment: it is necessary to check whether the keyboard plug has fallen out of the socket or whether it is securely connected. Cables can be disturbed during cleaning or, as is often the case, by pets.

If the plug is in place, it may be due to an operating system failure. The plan is as follows: first remove the keyboard plug from the socket and plug it back in after a few seconds. If that doesn't help, restart your computer. In the overwhelming majority of cases, this is sufficient for troubleshooting.

If you are using wireless device, check if the battery in it is dead.

Theoretically, any keyboard, of course, can fail, and even though this is practice is extremely rare, it is worth checking its performance by connecting it to another computer. If it doesn't work there, obviously, you need to buy a new one. At the same time, note that if you have a PS / 2 gadget, then the connector is sometimes the cause of the problem. Rough handling may cause the connector legs to bend and you will need to carefully align them with tweezers.

The problem may not be caused by the keyboard itself, but by damage to the driver responsible for its operation. In this situation, you will have to update the driver to latest version... How to do this is described below.

Keyboard doesn't work on new computer

If the keyboard does not turn on on a computer that has not yet been used, check BIOS support for it. Open the BIOS menu and find the USB Keyboard Support item. If the position is Disabled, you should change it to Enabled.

The impression that this device lives his own life and periodically stops working according to his own mood. The most common reason that it starts to shut down suddenly is in wire damage... Less often - in a broken port (as a rule, this happens when using a USB connection). If after reconnecting to another uSB port (or using an adapter to PS / 2) the problems have not disappeared, most likely the manual will have to be changed.

There are situations when the keypad refuses to work in Operating System Windows. Moreover, if you go to BIOS, it turns out that there are no problems with its work. The first step in finding a way out of this situation may be to install the latest drivers. They can be found on the official Microsoft Hardware website.

If the problem persists, you will have to reinstall the drivers manually, or restart the keyboard. First you need to disconnect it from the computer, and if there is an autonomous power source, disconnect it too. You need to open the Device Manager, for which, if the keyboard does not work in Windows 7, you should take the following steps: after clicking the "Start" button in the "Start Search" field, enter the name of the device, and then in the "Programs" list find the item "Device Manager" ... Enter the administrator password requested by the system or confirm it.

If your computer uses Windows X P, after clicking the "Start" button, select "Run", enter the command devmgmt. msc and click OK. After double clicking the "Keyboards" column select the device that is in use and click on its name with the right mouse button. Then select the "Delete" command. If there is no device in the list, then it was automatically deleted when disconnected from the computer.

After restarting your computer, plug the keyboard into it (if it has an independent power supply, turn it on first). The drivers will be reinstalled by the computer automatically after it is detected.

The keyboard does not work partially

Sometimes users are worried about the fact that some buttons do not work. Novice users sometimes forget to enable the Num Lock button to display numbers when pressing the corresponding keys on the right side of the manual.

Sometimes under the keys of mechanical types of devices fall crumbs and small debris, which prevents them from being pressed completely. In this case, clean the keyboard. Depending on experience and skill, this can be done independently or at a service center.

If you have purchased an expensive keyboard with a lot of extra buttons, you may need to install additional drivers for it to work properly. Without them, if the device will work, it will not work completely, some buttons will be "dead". Everything required drivers can usually be downloaded for free on the manufacturer's website.

Desktop computers have two key input devices: the mouse and the keyboard. Therefore, when any crash occurs and the keyboard / mouse stops working, the computer actually turns into useless hardware. We have already considered, and in this article we will analyze why the keyboard of stationary PCs may refuse to work.

Checking the wires

The keyboard is connected to the system unit through two types of connectors - outdated PS / 2 or modern USB.

Initially, check the integrity of the wire itself, if there are no defects, proceed to inspect the connectors. In the case of PS / 2, the contacts of the plug are often bent, in the worst case they can be completely broken off when the user inserts the plug with all his might, and it does not fit into the connector due to the wrong location. If you have a newer keyboard with a USB connection to a computer, then simply switch the keyboard to a different USB port, as the contacts in them may also fail. ATTENTION: it is recommended to disconnect and reconnect the keyboard when the computer is turned off, or after connecting to restart it. For example, in the case of a PS / 2 connector, there is a 90% chance that the keyboard will not work without restarting the computer.

Updating the driver

If you have a special gaming keyboard or similar multimedia ones with a bunch of additional functional buttons, then drivers should be included with them. They can also be downloaded from the manufacturers' official websites. In case of simple keyboards you can update the drivers using Windows itself. A software glitch may cause the keyboard driver to crash and must be reinstalled.

Open the menu Start - Control Panel - Device Manager... In the list of devices, find Keyboards, click on the selected right mouse button and press Update drivers... For Windows to update the driver itself, the computer must be connected to the Internet. If for some reason the update failed, you will have to find a driver for your keyboard model on the Internet yourself, download and install it.

As a rule, these two reasons lead to inoperability of the keyboard on stationary PCs in 99% of cases - inoperative connector contacts and failed drivers. The remaining 1% is when the keyboard itself breaks down, as well as very exotic cases. For example, viruses that block the keyboard; flown or incorrectly set BIOS settings.
