Sometimes the keyboard doesn't work. Wireless keyboard and mouse not working

20.08.2019 Internet, Wi-Fi, local networks

The problem when the keyboard does not work on a computer or laptop is not uncommon. This situation is faced by both beginners and experienced users who have been working at a computer for more than one year. Let's see how you can find a solution to the problem when the keyboard stops working, keys stick or does not respond to pressing.

What could be the reasons for the breakdown and their solutions

I decided to write an article in the form of points so that you can go through them and find out why the keyboard does not work.

The blog has information when the keyboard in the laptop refused to work: "".

Novice users usually immediately rush into panic and forget about the most commonplace things. The very first thing to check if the keyboard is connected to the system unit (directly to the motherboard).

Disconnect the keyboard for a while (5-10 seconds) and reconnect it.

If your keyboard suddenly stops working, try restarting your computer. Sometimes restarting Windows helps.

It is now very popular to use wireless keyboards and mice. If you have used wired keyboards before, but at the moment you have a wireless one, then I remind you that the batteries are running low and you need to recharge them from time to time.

All modern keyboards are connected through a special connector called a USB port. If there is a free USB port, try plugging your keyboard into it. In the event that all ports are busy, unplug the printer or any other device to test the USB port for operability by connecting a keyboard there.

If you have children at home, then it makes sense to check for unnecessary items, in the connector or in the system unit (motherboard) itself. Once I witnessed a situation when there was paper or 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 plug it in 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.

What should I do, the keyboard does not work, but you have already done all the above methods? If you have an old-style keyboard called PS / 2 (write in half), then pay attention to the legs. They can be bent or one of the legs is completely absent. These legs can bend when connecting the device in a hurry, they do not bend by themselves. If there are no legs, then you will have to change the keyboard, if it is curved, then you can correct it with improvised means, for example, a screwdriver or a knife.

For the future, you should know that the purple connector is designated as the keyboard, and the green is the mouse.

If there are crumbs of food in the keyboard, or you simply dropped it or hit it, then it makes sense to disassemble it. If you use the keyboard for a long time or if you hit it, the rubber band inside may slip. When you disassemble the keyboard, you need to tweak and clean the gum if necessary.

Wipe the rubber band with a dry cloth, and the keyboard itself can be wiped with a damp cloth.

When disassembling the keyboard, it is important for novice users to remember where all the keys were. In order not to get confused in the location of the keys, you can find a photo on the Internet that will be identical to your keyboard. Also, when parsing, you can put the keys on the table in the order they were, or take a photo with your cell phone.

If the USB keyboard does not work, then you can look in the BIOS to see if it is disabled. But there is one caveat, in order to enter the BIOS we need a keyboard that will work on this computer. There is an exit. You need to get a PS / 2 keyboard or a USB to PS / 2 adapter. By connecting PS / 2, you can now work with the keyboard. Go to BIOS and switch USB Keyboard Support to Enabled. We also see that the USB Controller is Enabled.

Another reason for the failure of the keyboard is, perhaps the driver stopped working on the computer, which is responsible for the correct functioning of the keyboard. In such a situation, there are a number of steps you can take to try and fix the problem yourself.

First, you can do a system restore or roll it back to the date when the keyboard worked normally. Stretch your memory to remember the approximate date;).

Second, try updating your keyboard driver. To do this, go to the "Device Manager" and find our keyboard. Right-click and select "Update drivers ..."

If when buying a keyboard it came with a CD with drivers, then you need to install them. Remove old drivers before installation.

When the keyboard does not work: what to do and how to find out the cause, you now know. Just in case, go over all the points, you may have missed some of them.

Keys don't work in a program or game

Users who like to play games sometimes face a problem when some part of the keys does not work.

If the keyboard works, but after entering the program or any game, some keys refuse to work. In this case, it will be appropriate to first look at the assignment of the keys. If you are not satisfied with how they are displayed, then look for their setting in the game itself. In some games, all changes need to be saved, so do not forget about it.

Usually, all hotkeys in programs are the same, but there are exceptions. To change them, find the key setting in the program itself. Change the part of the hotkeys that does not suit you to the ones you are used to.

If your keyboard does not work, and you tried everything that I told you here, then you can buy the most ordinary keyboard, since their cost is not great.

Do you like to eat over your laptop? Then this video is for you:

If your computer keyboard does not work, then you have come to the right place. Here you will find step-by-step instructions for solving such problems. There can be many reasons for such a problem, and there are many solutions to them. First, you need to understand exactly when this problem occurs and what it is connected with. Usually, the keyboard can explode even when the operating system is loaded when entering a password or during work when entering text. The first malfunction depends on the type of keyboard, and the second on mechanical stress on it.

Why does the keyboard need to be cleaned periodically

I want to say right away that if you do not part with the keyboard even while eating, then choose a time, turn it off, and take good care of it.

Sticky keys and incomprehensible keyboard work are most often experienced by those people who like to chew on something while working at the computer, or, even better, drink beer or soda.

If your keyboard is not wrapped in a protective film, then all the crumbs and liquid from the bubbling drink will be inside it. You don't have to spill drinks on the keyboard. It is enough to put a glass of bubbling drink next to it, and all these bubbles will settle on the keyboard, and even get inside it.

And if you like to nibble on seeds or nuts, then your keyboard has probably accumulated crumbs, which will be enough for a good lunch for a hamster. Don't believe me ?! Then take the keyboard in your hands, turn it over, and shake it over the table.

What to do if it doesn't workUSB-keyboard

Check the keyboard connection. If it is wired, then the wires inside the cord could break, either at the base or at the USB connector.

If the keyboard is wireless, check the batteries inside the keyboard and the USB transmitter connected to the computer or laptop.

It happens that the transmitter or the USB connector where it is connected is faulty. If it is a USB connector, plug the transmitter into a different connector.

Let's check the keyboard connection settings inBIOS:

Enter the BIOS settings (we read how to do this in the article);
We are looking for the item USB Keyboard Support or Legacy USB (it depends on the BIOS version) and switch Disabled to Enable.

Perhaps with a USB keyboard you will not be able to enter BIOS settings. Then you need to find a keyboard with an old PS / 2 connector or find an adapter for an old connector.

What to do if the keyboard does not work via the protocolPS/2

Finding a PS / 2 keyboard in a store is not easy, but some still use it and can sometimes fail too.

In order for the keyboard to work again, you need to reinstall its driver:

Right-click on the "Start" menu button and select "Device Manager" from the drop-down list.
Find the keyboard in the list of devices and expand the list. Usually, if there are any problems with a device, then there will be a yellow circle with an exclamation or question mark next to this device. Click on the inscription "HD Keyboard" with the right mouse button and select the action "Delete". Confirm your action and close Device Manager.

Instructions: What to do if the keyboard does not work on the computer

The keyboard is the main tool for entering information, without which it is impossible to work on a computer. Most often, in order for this device to work flawlessly, it is enough to simply connect it to the computer, and it will install all the necessary drivers automatically. This happens in most cases, but not always. There are situations when, when the keyboard is connected to the USB or PS / 2 connector, it is not detected on the computer and does not show any signs of operation - the indicators are off, and the buttons do not work. As part of this article, we offer instructions on what to do if the keyboard on your computer does not work.

Why the keyboard does not work on the computer

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

Due to the simplicity of the process of connecting a computer, we can conclude that there are only 2 reasons why the keyboard does not work on a computer:

Mechanical. Problems may arise directly with the keyboard or the wire that connects it to the motherboard. A broken connector on the motherboard may also be the cause of the malfunction.
Software. The keyboard drivers are installed automatically, but during the installation of any software failures may occur, and this situation is no exception. In addition, problems may not be observed at the operating system level, but in the BIOS, where the appropriate settings for the keyboard are disabled.

Depending on which connector the keyboard is connected to the computer, we offer different solutions to the problems that arise.

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

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

If the USB keyboard does not work when you turn on your computer, do the following:

It is worth noting that users whose keyboard is connected to the motherboard via USB may have problems navigating to BIOS on the computer's boot screen if they are using an old version of the basic software. In this case, you need to find a keyboard with a PS / 2 connector or use the appropriate adapter.

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

Keyboard makers are moving away from the PS / 2 connector in favor of USB. It is very difficult to find a keyboard with a PS / 2 connector on sale, but if you come across such peripherals, and it does not work when you boot windows, most likely the problem is related to the drivers. To make the keyboard work, 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 during the installation of the i8042prt.sys or kbdclass.sys driver.

Wireless keyboard stopped working

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

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

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

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

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

If the receiver is 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, then make sure the drivers are installed correctly.

If that does not help, replace all batteries, even if the tested keyboard software indicates that there is a charge.

Why is the keyboard not working on the computer and what should I do?

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 talk about a computer keyboard, and I will sit down on a laptop keyboard 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 of the system unit. It is possible that a cat passing by touched the keyboard plug and it simply fell out of the nest.

The next possible option is 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 mice) 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 associated with entering numbers - users complain that the right side of 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 a fairly expensive keyboard with a lot of extra 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 the latest version, or we roll back the system a few days ago when the keyboard was working.

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 a wireless device (keyboard) that 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. This also fully applies to hotkeys.

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 of this device is usually unjustifiably expensive.

What to do if the keyboard won't turn on

Even users with significant experience may experience some confusion if, for some reason, when turning on the PC and loading windows, the keyboard stops working. A variant of the problem is when only individual buttons do not work. Less experienced users of windows and computers in general immediately think about repairing or buying a new device. But maybe the problem is in the operating system - did the keyboard stop working? If you have another at hand, then it will not be difficult to check the performance of the first one. But what to do when there is no such possibility? We will try to figure out why the keyboard on the computer does not work and how you can solve this problem.

For what reasons did the keyboard stop working?

In total, there are five main situations, the occurrence of which can lead to the lack of recoil of the device and the reason why the keyboard stopped working when turned on:

direct breakdown;
malfunction of the PS / 2 / USB port;
lack of normal contact between the keyboard connector and PS / 2 / USB;
problems with the wireless keyboard;
blocking the device in windows by a virus or malware.

Banal breakdown is the most common reason that your keyboard does not work. As for the port malfunction, although it is rare, it can burn out for some reason. Despite the fact that users rarely encounter such a situation, it definitely should not be ruled out. It is also possible that the keyboard — both USB and PS / 2 — is not working because you incorrectly plugged the connector into the port. Another variant of its inoperability lies in the bent contacts.

Date of publication: 10.05.2012

There are many reasons why your keyboard might not perform well or show any signs of life at all. First, you need to immediately determine the root cause of such a breakdown: software or hardware. In simple terms, either the keyboard itself is faulty, or the problem lies in the Windows settings.

So, in order ...

The keyboard works, but some keys do not work well (sticky, do not respond to pressing, etc.).

The reason is usually simple - the keyboard is dirty.

You need to disassemble the keyboard and clean it. It doesn't matter what kind of keyboard you have (usb, standard, wireless, built into a laptop). Turn the keyboard over, remove a few screws. Here you will see that there is a rubber pad under each button. Sometimes it happens that the pad breaks or "slides" from its place- as a result, the corresponding key does not work. Then you just put everything in its place.

The key buttons can be wiped clean with anything, any cleaning agent. But it is better not to touch the translucent film and everything else. By the way, so as not to get confused where which key should be, take a picture of your keyboard in advance. Of course, you can later find your keyboard model on the Internet and arrange the keys. But, nevertheless, it is much more convenient to take a photo of your keyboard. Some even number the keys with a pencil so they don't get confused later. After "cleaning", place the keys in their places, place the rubber pads (they can be placed in any order - they are all the same). The work is painstaking, but the result will be a great working keyboard.

Plug problem

If you have a classic keyboard (with a round purple plug), it sometimes happens that the small legs of the plug may bend.

In general, this type of connector is called PS / 2. Purple is for the keyboard, green is for the mouse. If you forcefully insert the plug, the legs may bend. Then you need to take tweezers (or small pliers) and straighten all the legs.

USB - keyboard

This is an ordinary keyboard, only it is connected not to the PS / 2 connector, but to the USB connector.

If such a keyboard does not work when connected, then the problem most likely lies in the BIOS settings (SETUP). When you start the computer, press Del (or F6, everyone has different keys).

And since you cannot use a mouse in the bios settings, a reasonable question appears: "How can I press Del at startup, and how will I configure bios if the keyboard does not work for me ???!" The problem is solved simply - go to your neighbor and ask him for a keyboard for 5 minutes :)

Wireless keyboard

I'll ask you a stupid question: "Have you charged your keyboard?"
Surprisingly, usually the battery just runs out and people forget to recharge it.

It also happens that Windows simply cannot install drivers for your wireless keyboard. Then search for drivers on the Internet manually.

Drivers

It happens that some new installed program unknowingly corrupts the keyboard drivers. If you have Windows 7 installed, then driver problems should not bother you. The system itself installs and restores the drivers. Usually, you just need to restart your computer.

But there are times when the driver gets messed up or the new driver doesn't work well. In such cases, you can do two things. First, restore the system to the day when the keyboard worked fine. Secondly, you can go to the device manager and update the drivers, or view their properties by looking at the diagnostics.

Keys don't work in a particular program or game

You should find the settings for a program or game and look at the key assignments. In general, check out the settings. In games, as a rule, the keys can be reassigned. And in the programs, see the list of hot keys.

Some other tips

If the computer emits three long beeps (beeps, sounds) when you turn it on, this means that you inserted the keyboard incorrectly. Just pull out the plug and plug it in again.

If the keyboard does not work suddenly, first of all, check it on other computers. If you have only one computer (usually everyone has this), then go to your neighbor and check the keyboard on his computer.

Sometimes it happens that a (computer) mouse starts to work poorly - to jam and freeze. The mouse will continuously appear to be disconnected and connected (and the computer will beep to indicate that the device is connected). Due to the fact that the computer will constantly recheck the input devices connected to it, the keyboard will also begin to work poorly. Then just pull out the mouse and recheck the keyboard.

There are also times when the mouse and keyboard cannot work at the same time. This happens EXTREMELY rarely, but it can happen. In some unknown way, some mouse models are simply incompatible with some keyboard models (?!). I have personally encountered such a case only once. It is usually possible to trick the computer in this case. You need to find a mouse or keyboard in the registry and assign them different names. Sometimes it helps ... For the same reason, joysticks (gamepads) may sometimes not work in games. For example, a game only lets you use Microsoft gamepads, and the others just don't work. Then you need to find your gamepad in the registry and rename it to the name Microsoft.

If the keyboard does not work, and you still need to find something on the Internet (for example: drivers for the keyboard), then you can use the on-screen keyboard.

That's all. Ask questions - I will be happy to answer them.
Thank you for your attention!

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 are texting on social networks or typing the most important work in your life: thesis, master's, or much more promising professorship.

You start to panic. What to do? Calling a master or buying a 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 may think for a long time why the wireless keyboard on the computer does not work, but the main breakdowns and problems occur most often 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.
