What to do if the keyboard turned off. Run the keyboard on the PC with Windows

Basically, the keyboard on the laptop ceases to work through the problems with the driver or due to the contact of the contact to the motherboard.

If some keys do not work, then usually through the accumulated dust or hitting third-party objects that prevent the contact closure when pressed them. In this case, you need to clean the contacts after removing the non-working keys.

Everyone may encounter the integrated keyboard in the laptop. It can not fully work or only partially respond to click on some keys.

First you need to determine the nature of the fault - whether the hardware is a hardware associated with the physical connection, or the problem of the software (incompatible driver, incorrect device configuration).

If the fault arose at the hardware level, the keyboard will not respond at all to any of the keys.

If the problem is associated with software, the device will be partially responding when you press some buttons, such as Fn (Function).

In the top row there are function keys (F1 - F12). They have an icon indicating their action when you press the Fn key. For example, on my laptop, the FN + F5 combination is responsible for switching on / disable the touch panel. Try all combinations and other CAPS LOCK, NUM LOCK keys and others. If some of the keys work, this means the problem arose at the program level.

Now go to the troubleshooting steps. First, remember, were set before the keyboard stopped working, some kind of program or driver? For example, a graphics tablet, the SYNAPTICS driver or could be made to setting the input device. If so, cancel the changes, delete the newly installed programs and see if it solves the problem. If after that it was possible to eliminate it, then the changes made led to the termination of the keyboard operation.

Problems may also occur after installing updates in Windows 10.

To solve problems, connect the external keyboard and the mouse to the laptop using the USB cable to follow the solutions below.

Before try rebooting the laptop.

Turn off your laptop completely. If you cannot complete the work, press the Power button for a few seconds to complete the work.
After switching off, remove the battery and wait 2-3 minutes.
Connect the battery again, connect the power cord and turn on the laptop.

Reinstall Driver

If the solution with the laptop is turned off / enabled, try installing the default drivers. These drivers stored in BIOS are initialized when the computer does not find the correct drivers for your device. This method will help determine if the drivers failure or in the hardware.

Setting up keyboard parameters

Work facilitation settings are available in almost all versions of Windows. But sometimes they do not work properly and cause malfunctions when using a laptop keyboard. Try to disable these parameters and check if the problem is eliminated.

In the Windows 10 paging line, type "Simplify work". As a result of the search, select "Center for Special Features".

Click the "Lightweight keyboard" tab.

Uncheck flags from the fields:

Enable keyboard pointer management;
Switching on key sticks;
Enable switching switching;
Enable input filtering.

Now restart the laptop, check if the keyboard works.

Hardware problems

If a malfunction occurs at the hardware level, it may be necessary to replace the keyboard. But first try to clean it, since dust particles, and foreign items may interfere with the contact of the contacts of the buttons.

To clean them, turn the deployed laptop screen down and shake well. You can produce dust with compressed air using a vacuum cleaner.

Remove the keyboard from the laptop and check the density of connecting the connecting loop to the connector.

Did you have a situation when you, working at a computer, suddenly noticed that the keyboard refuses to print? And it doesn't matter whether you are rewritten in social networks or print the most important work in your life: thesis, master or much more promising professorship. You are wondering why the keyboard does not work on the computer. Overload the operating system in the hope that everything will be worse, but not. The keyboard, as before, does not respond. You start panic. What to do? Call a wizard at home or buy a new keyboard? And if it is a laptop? There is an exit!

To resolve this unpleasant breakdown, it is necessary to figure out which type of keyboard you have connected.

Computer keyboard connection type

USB keyboard. Most often in our time it is this type. The USB keyboard uses Plug-and-Play technology ("Connect and Work"), so the problem most often occurs exactly with connection. As soon as the keyboard stops responding, first of all you need to turn it off and back to connect to the USB port of your computer device. Perhaps simply moved the contacts. Usually such actions lead to the elimination of the problem. But it happens that the breakdown is not in the keyboard itself. If these actions have not led to a positive result, there is a chance that the port itself broke into the computer. Try connecting the device to another device or at least another USB connector of your PC. Having done these actions, you will already be able to discard some guesses about why the keyboard does not work on the computer. Windows XP, 7, Linux is differently configured to connect devices. There is a chance that the problem is in software or operating system installations.

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 connections for connecting. It happens that with an inept connection of the connector to the computer port, one of the contacts may be rushing. It must be aligned so that the keyboard earned. If the keyboard stopped working while working on it when the PC is turned on, be sure: the problem is in the operating system or software. Perhaps some kind of process inhibits her work. The main difference between the PS / 2 computer keyboard from the USB is that when the device fails to work, you must restart the computer so that it starts again. After all, this is not a plug-and-play technology.
Wireless keyboard is a modern type of information input device, but this does not mean that it is without flaws. He can also refuse to work, like other types of devices. You can think for a long time why the wireless keyboard does not work on the computer, but the main breakdowns and problems occur most often in the case when something blocks a USB receiver. In this case, it is necessary to clean the computer desk from unnecessary things and see if it works now. In fact, the wireless keyboard is the same USB peripheral device, with the only little difference: there are no wires here. In this regard, it is necessary first to check the signal blocking. If no changes occurred, then it is necessary to follow the actions described in the computer keyboard USB item.

Troubleshooting BIOS

You have done actions on mechanical elimination of the problem, but, unfortunately, it did not help. Panic covers you. Why does not the keyboard on the computer? Windows 7, first of all, you must restart. Perhaps the problem will be eliminated by itself.
Try to press the "ESC" button several times to check whether the display autorun menu appears. In case there is no program response, you must replace the keyboard - the problem is not in the software.
If the autorun menu triggered, press the F10 key to call the BIOS menu. In the settings you need to set the default values, this is done by pressing the F5 key. Some devices can have other hotkeys.
After making changes to the BIOS, you must restart the operating system.
If, after the actions done, you still did not solve 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 "Equipment and sound", under which the devices and printers are located. It is this section that we need. Clause in the right mouse button, you must select "Device Manager". Do not forget that the administrator rights must be necessary, in another case you will not be able to change the settings of hidden devices. So, in the new open window we are looking for the desired keyboards and try to solve the problem why the keyboard does not work on the computer. Windows 7, 8, XP are slightly different to their interface, so the path to the setup menu can not coincide a little. Calling the object control panel, you must select reinstall and update the configuration of the equipment and drivers. After rebooting the computer, the equipment must work correctly.

The problem of pressing one keyboard key of several characters

Sometimes during the set of text from the keyboard, there is a situation when the keys are sticking and several characters are printed. And the problem is not that you click on the keys too long. All the essence - in the settings of the keyboard response. To change these parameters, you need to manually register the word "keyboard" in the search bar in the start menu. A new window will appear before your eyes, when you open which it is necessary to properly adjust the re-symbol input delay rate. From now on, you will not worry about why the keyboard does not work on the computer correctly.

1 way to eliminate the inoperability of the keyboard outside the operating system

Often there are situations of the keyboard failure due to the incompatibility of the drivers on the operating system. There are different versions of Windows: 32 and 64 Bit. What do they differ and why do they need different drivers? The main difference in the processing of different amounts of RAM. That is why it is necessary to install various types of drivers so that at the most inappropriate moment does not panic, why the keyboard does not work on the computer. Windows 8, 7, XP, Linux requires setting different types of software. But to find out if this is the real cause of the problem, you need to restart the computer and see by pressing the keyboard numlock and Capslock keyboard keys, check their performance using tanning indicators.

2 Method of troubleshooting keyboard via CMOS

Another way to check the functionality of the keyboard outside the operating system is to go to the CMOS settings and try the keyboard operation in safe mode. Sometimes there is a malfunction of the operating system, secure mode will fix this breakdown. If you refuse the CapsLock and Numlock keys to go to the first way.

The computer device makes a squeak when set from the keyboard: elimination methods

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

In the resulting control panel, there is a point of their change. You need to go through this link, remove the keys sticking the keys and go to their settings near the "Simplify Text Set" item. In the new window that opens, remove a tick near the sticking of the keys with a fivefold key to the SHIFT button. We save the results by clicking on the OK button, after which the previous keyboard settings window automatically opens. It is removed in it near the sounding point of the switches by pressing the Num Lock button for 5 seconds. After saving the results of the settings, the computer device will no longer produce meticulous audio signals.

Refuses to work a digital keyboard

Some users buying a peripheral device are sometimes wondering why the numbers are not working on the keyboard on the right. On a computer, this situation happens quite often, especially on the Ubuntu operating system. What to do in this case? Try simply pressing the combination of two keys: SHIFT + NUM LOCK. Most often it helps. There is a chance that the mouse control is configured from the numeric keypad. To disable it on the Windows operating system, you must press the Alt + Shift + Num Lock key combination. There is another more complex way to transition to optical mouse settings. But why complicate my life when you can solve the whole problem by pressing the keyboard shortcut?

Why the keyboard does not work on the computer when you turn on: solving the problem

To solve this problem, it is necessary to follow these steps:

Check connection itself. No matter what type of keyboard: USB, wireless or PS / 2. If the problem is in connection or signal loss, the keyboard will not work.
If everything is in order connected with the connection, you must download the new version of the software that is compatible with your operating system, and reinstall it for your keyboard.
When and reinstalling the driver did not help, it means that you need to configure everything by manually via the BIOS, CMOS or "control panel".
If you have the ability to connect the keyboard to another computer device, check it with its performance on it. In each operating system, software settings are located in different ways. It is necessary to know well the operating system interface to solve the problem, why the keyboard does not work on the computer. Windows 8.1 - perhaps the most difficult system for software change settings. But to change the settings of the keyboard, you will not need a lot of knowledge. It is necessary to clearly follow the instructions, and then your peripheral device will earn up as quickly as before.

Possible causes of the inoperability of some keys on the keyboard

There are cases when due to non-accuracy or negligence, the user of the computer device sheds water, tea or other drinks on the keyboard. Well, if this was done by the owner of the computer, because he knows where there are problems with the peripheral device. But when someone did someone else and did not admit, the owner will scratch the back for a long time, why the USB keyboard does not work on the computer. But most often it happens that certain buttons stop working. Then you need to disassemble and manually clean the keyboard, and if it has already oxidized, then completely change. After all, there is little chance that it will now work, as before.

Users to note

Now you know the possible causes of the battery breakdown. Some users will be new to know that the on-screen keyboard is automatically installed in any operating system. In case of failure of the peripheral device, it will definitely be to help you.

The keyboard is one of the main information entry tools on the computer. Without it, it is impossible to perform some operations in the OS and manage the process in games. The breakdown of this device also deprives us of writing messages in messenger and social networks and work in text editors. In this article we will discuss the main reasons and analyze the solutions to this problem.

To begin with, we will understand why "Klava" can refuse to work. There are several reasons here. Connection ports, cables, electronic or mechanical fillings of the device may be faulty. Also can "hooligan" control software - driver or BIOS. We will talk about these and other problems below.

Cause 1: Phuch fault

The first thing to pay attention is whether the keyboard itself is working. Check it in two ways. The first is to connect it to another PC. If everything is in order, then the problem must be sought in your system. The second is to start the computer. When the operating device is turned on, the signal must be filled - blinked by LEDs.

Another fault type is the failure of the connection port that is two types - USB and PS / 2.

Ports

Ports may be damaged by mechanical path, as well as "burned" due to short circuit or voltage jumps. In the case of YUSB, you can try to connect the keyboard to another similar port. Note that USB connectors can be broken into groups. If one of the ports does not function, then the whole group may be non-working.

With PS / 2, everything is more complicated, since such a connector on the overwhelming majority of motherboards are only one. The only option in this situation is to find another "clave" with such a connector and connect to the port. If nothing has changed, it means that the nest is defective. You can save the port, only by contacting the service center.

Cables and plugs

To identify the cable fault and the plug that the keyboard connects to the computer is quite simple. Enough when the PC is enabled, move the wire at the entrance to the "clave" and near the connector on the motherboard. If LEDs light on the device briefly, then there is a failure of these elements. You can replace the cable as independently, the other, serviceable, and simply attribute the device to the master.

Electronic and Mechanical Stuffing

About these malfunctions indicates the inoperability of several or all keys when burning indicators and other features of the device definition by the system that we will talk later. In any keyboard there is an electronic control module, which is quite rare, but still fails or works incorrectly.

The impossibility of pressing can also be caused by a violation of tracks or short circuit due to water entering. In addition, one of the keys can stick up without giving others to function normally. We will understand in these situations in more detail.

First you need to exclude sticking. Check if it is possible, you can use the on-screen keyboard. When you start this application, it will be seen that the key is shown in white.

To eliminate this problem, it is necessary to replace the membrane, previously disassembled the device. If the keyboard is mechanical, then switches will have to change, which can be mounted both by soldering and without it. In any case, it will be done to do it yourself quite problematic if there is no necessary equipment and consumables in the form of solder, flux and, actually, the switch itself. Exit - contact a specialized workshop.

The easiest way is to press a problem key several times, perhaps everything will come to normal and without repair.

If liquid got into the "clave", then the presence of a short circuit in its electrical part is likely. The solution will be the disassembly and drying. Please note that if the membrane type device, then sweet tea, beer and other fluids other than clean water, even after drying can remain between the layers of the film with the tracks. In this case, only flushing films under running water will save. True, there is one nuance here - the tracks can oxidize and lose their conductivity.

In any case, if it is even possible to reanimate the device, it is worth thinking about the acquisition of a new one, since it is not far from the mountains full of its failure. The keyboard fluid is death.

If you have not shed water to the "clave" and the keys on it do not mess, then the last thing that can happen is a breakdown of an electronic control module. For cheap devices, its repair or replacement is unprofitable, so you have to buy a new "board". Dear you can try to pass to the service center.

Cause 2: BIOS

The keyboard can be disabled in the BIOS settings. This applies only to devices with USB connection. At the same time, the "clave" cannot be used to select the startup parameters of the OS and other operations performed without booting Windows. In the title you need settings should be present "USB KEYBOARD" in different combinations. In most cases, you need to set a value. "Enabled" For this parameter.

Keyboard - the main tool for entering information, without which the work on the computer is not possible. Most often, this device will work correctly, it is enough to connect it to a computer, and it will install all the necessary drivers automatically. This happens in most cases, but not always. There are situations where when connecting the keyboard into a USB or PS / 2 connector, it is not defined on the computer and does not submit any signs of work - the indicators are not lit, and the buttons do not work. As part of this article, we offer instructions to do if the keyboard does not work on the computer.

We recommend reading:

Connect the keyboard to the computer as simple as possible - it is enough to insert it into the corresponding connector on the motherboard, and then the device will start working. There are wireless keyboards, a radio receiver from which is inserted into a USB connector, after which the device works if the distance between the transmitter and the device is respected.

Due to the simplicity of the computer connection process, it can be concluded that the reasons for which the keyboard does not work on the computer, only 2:

Mechanical. Problems may arise directly with the keyboard or wire that it connects to the motherboard. Also, the cause of the malfunction can be a broken connector on the motherboard.
Software. The driver for the keyboard is installed automatically, but in the process of installing any software may occur, and this situation is not an exception. In addition, problems may not be observed at the level of the operating system, but in the BIOS, where the corresponding settings for the keyboard operation are disabled.

Depending on how the keyboard connector connects to a computer, we offer different solutions to emerging problems.

What to do if the keyboard does not work on the computer using the USB protocol

The most common keyboard connection interface to a computer is USB. The speed of transmitting information from the peripheral device is enough to the computer, both through the USB 2.0 protocol, and via USB 3.0, so there is no difference in which connector to connect the keyboard.

If a USB keyboard does not work on the computer, you must do the following:

It is worth noting that users whose keyboard is connected to the motherboard via USB, there may be problems with the transition to the BIOS on the computer boot screen if the old version of the basic software is used. In this case, it is necessary to find the keyboard with the PS / 2 connector or use the appropriate adapter.

What to do if the keyboard does not work on the PS / 2 protocol

Keyboard manufacturers try to move away from PS / 2 connector, refusing it in favor of USB. To commerce the keyboard with PS / 2 connector, the connector is very difficult, but if you got a similar peripherals, and it does not work when booting Windows, most likely the problem is related to the drivers. To the keyboard earn, you need to do the following:

It is worth noting that a similar problem with keyboards connected via PS / 2 protocol, most often occurs due to an error when installing the I8042PRT.SYS or KBDClass.sys driver.

The keyboard is the main tool when working on a computer, without which the work is almost impossible. Of course, you can enter information using a mouse and on-screen keyboard, but this method is uncomfortable and full work will not work.

In this article we will tell you what to do if the keyboard does not work on the computer and consider all possible causes of this fault.

The keyboard is a pretty simple device and usually works correctly. However, there are cases when the keyboard indication is on, but nothing is printed.

Why the keyboard does not work: reasons

The reasons for which the computer keypad may not work two types:

Mechanical (cable break, moisture enter, excessive keyboard contamination, violation of the integrity of ports for connection and so on).
Software (software malfunctions, incorrect BIOS settings, incorrect drivers per keyboard and so on).

Consider all the main reasons due to which the keyboard does not work and troubleshooting methods.

Malfunction of the cable or port for connecting the keyboard

First of all, it is necessary to estimate the physical condition of the keyboard.

Look at the display of the CAPS LOCK and NUM Lock buttons. Most likely, if they work, then physically with the keyboard everything should be in order.

In your eyes inspect the keyboard cable. Maybe it ships or cut. For example, in many pet owners, pets overload the cable.

Also, check the visually of the keyboard connection port, there is no fractures or bends in it. Keyboard connection ports are two types - USB and PS / 2.

Very often it happens that in the PS / 2 port when you try to connect to a computer, people are laid out the tip of the cum and the keyboard connection does not occur.

If the keyboard USB cable and the connection port look good, then try to stick the keyboard to another computer USB port. Perhaps the port is spoiled on the computer itself. If the keyboard earned the keyboard in another port of the computer, then you have a problem with the USB port. Usually there are several on the computer and you can simply leave the keyboard connected to the port that runs.

In the case of the PS / 2 keyboard, you should check the performance of the keyboard connection port on another computer, as such a port on the motherboard is only one. To check the performance of the PS / 2 port port, you will have to find another keyboard.

Spilled fluid and contamination on the keyboard

The flooded keyboard is the headache of all the ITs and Golden lived for all service centers for the repair of laptops. Very often, people when working on a computer pour tea, coffee, beer and other liquids on the keyboard. As a result, the keyboard may fail.

As a rule, visually and smell, it is easy to determine that liquid was spilled on the keyboard. Carefully inspect the keyboard. Remove a pair of keys. If you see that traces of spilled fluid or food remained on the keyboard or under the keys, then you have two ways. Either buy a new keyboard, or meticulously disassemble a flooded keyboard, clean, dry and assemble back. With a lot of probability, the keyboard will work.

Previously, we already told in detail that at home.

Verification USB settings in BIOS

In the event of a power failure, the BIOS settings may change, which has an item on enabling and disconnecting USB keyboard support in the computer.

Additionally, in this way you can check the level of keyboard in principle, as it may not work in Windows, and in the BIOS work. In this case, the failure is caused by software or drivers.

To enter the BIOS and check the settings, do the following:

Turn on the computer.
Press the DEL button on the keyboard until the BIOS settings window appears.
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, switch to Enable.

You can at the same time put in the ENABLE state the remaining BIOS settings associated with USB. Perhaps you will earn ports on the front panel of the computer case, which once stopped working.

Software failure or drivers

Software failures are more prone to keyboard with old PS / 2 connectors. However, there are still quite such keyboards to use such keyboards, although manufacturers have almost ceased to release them.

To solve the problem with the non-working keyboard because of the software, you need to enable your computer and enter the desktop. Since the keyboard stopped working and does not print, and the password can be delivered to the account, you will need to use the on-screen keyboard and dial the password with the mouse.

Now, when you ended up on your computer desktop you need to get into the Device Manager.

In Windows 8 and Windows 10, right-click on the button Start and select Device Manager.

In Windows 7, click on the left mouse button on the button Start. Next, right-click on the word A computer and select Computer Management — Device Manager.

The device manager displays information about all computer devices. Open the keyboard branch. If an orange question mark is burning next to your keyboard, then the device is incorrectly installed in the system.

Right-click on the keyboard and select Delete.

The computer will re-interview all devices and install the keyboard correctly.

Factory marriage or keyboard service went to the end

Any technique tend to break and fail. If the keyboard is purchased relatively recently, you may have encountered a factory marriage. In this case, you can contact the keyboard manufacturer support and replace the device.

The fact is that many manufacturers value their reputation and without entering into a long debate with the buyer immediately send a new keyboard by mail.

If your keyboard is not the first year, then most likely it failed in service time and you should buy a new one.
