Do you press some letters on the keyboard of a laptop or computer, and completely different ones appear on the screen? Don't worry, it's easy to fix. If keyboard is typing wrong letters and symbols, there may be several reasons. I will discuss each of them and options for solving the problem below.
Reason #1: An additional keyboard is included, which is activated by the Fn key.
If you are using a laptop. Most likely the reason is the pressed FN key, press Fn + Ins (Insert) and try to print. In some cases, Fn + Num Lock should help.
As I said above, pressing the Fn key will activate additional characters attached to the buttons. Usually they are signed in a different color and drawn on the buttons in the corner.
If you're sure your keyboard doesn't have an Fn button, just read on. There are more ways below.
Reason #2: Sticky Keys is enabled.
Windows has a "Sticky Keys" mechanism, it is activated if you press one button or several buttons many times in a row. Very often, this mode is turned on by cats, walking on the keyboard or lying on it.
Disabling Sticky Keys is simple:
- Go to the start menu
- Find "Settings"
- Here is the "Control Panel"
- Next "Accessibility" or "Ease of Access Center"
- Look for "Shortcut Keyboard Shortcuts" or "Sticky Keys"
- Find the "Turn on Sticky Keys" checkbox and uncheck it.
Reason #3: Keyboard crumbs or other rubbish.
Everything is simple here, look visually at the keyboard if crumbs or other debris are visible between the buttons. Turn the keyboard over and gently shake until all or most of the crumbs fall out from under the buttons, then see if it helps. Repeat until all buttons work.
Reason #4: Problems with regional settings.
Check in the menu:
- Start
- Setting
- Control Panel
- language and regional standards
- Here the tab "Languages" and click "Details"
- Then check which keyboards you have, they should be Russian and English (USA).
Please note that next to the word Russian, there are no postscripts: Machine, Ukraine, Belarus, etc. If you had the wrong layout, then delete it and click on the "Add Language" or "Add Keyboard Layout" button. Then choose the correct Russian, without postscripts.
Choosing the right Russian layout
If both keyboards were correct, try pressing each letter in the English layout and see if the letters and symbols are pressed correctly, if they match what you are pressing. If so, please check your computer for viruses and once again, just in case, make sure that the correct Russian layout is added. Just in case, it will not be superfluous to delete it and add it again. If, on the English layout, discrepancies between what you press and what appears on the screen continue, then you have a problem with the keyboard itself and it needs to be replaced. Often this happens due to liquid getting on the keyboard.
If this article helped you, please write in the comments about it. Also, if there are problems and something did not work out, also write, I will try to help.
Fortunately, at the moment the keyboard is such a popular device that you can buy it even in a regular supermarket, not to mention specialized stores. Despite the simplicity of this gadget, problems and malfunctions can occur with it. One of the most well-known problems goes something like this: "the keyboard has stopped working." it just stopped and that's it. Today I will talk about why this can happen and how you can deal with problems. It is also necessary to add that in this case we will talk about a computer keyboard, and I will talk about a keyboard for a laptop next time, since there is a very big difference between them.
Causes of problems and solutions
Where to start? First of all, don't panic. Yes, that's right, because in 90% of cases your problem is very easily solved.
- If you have a pet that loves to climb everywhere, I recommend 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 just fell out of the socket.
- The next possible option is some kind of glitch that occurred in the operating system. For such cases, there are two solutions to the problem. Firstly, unplug the plug for a few seconds and plug it back in, and secondly, you can restart your computer if the first option did not help. After rebooting the PC, the device starts working in 90% of cases.
- If you are using a PS / 2 keyboard, then carefully inspect the connector itself. The fact is that his legs could be bent, which must be aligned, otherwise he will not work. To do this, you will need tweezers (ideally) or something sharp like knitting needles.
- Most modern keyboards (as well as) connect to a PC based on a modern USB system. It is recommended to change the USB port and check if the device works. Ideally, it is better to check its performance on another PC or laptop.
- Theoretically, it is possible that the keyboard died a long time, in other words, it fell into disrepair. However, in practice this happens very rarely, moreover, often only one or several buttons fail. Checking this is easy - connect the device to another computer or laptop.
- One of the funniest problems associated with the introduction of numbers - users complain that the right side of the gadget, where the numbers are located, does not work. In fact, it connects on request with the Num Lock button, which is located above the numbers. This is done in order not to accidentally click on the numbers.
- Often on the keyboard in those places where the buttons are located, the rubber band that is located inside the case slips. Sometimes various crumbs and other small objects fall on it. To get rid of them, the keyboard must be disassembled and cleaned. By the way, large crumbs can get under one of the keys and it will stop being pressed. In this case, it is enough to remove only one key, which, fortunately, is very easy to do.
- If you have a fairly expensive keyboard with lots of extra buttons, you probably need to install separate drivers. Without them, the keyboard can and will work, but apart from individual buttons. You need to install drivers for the device, which can be found on the official website of the manufacturer.
- By the way, about the drivers. In some cases, a problem arises not with the keyboard itself, but with the driver that is responsible for its operation. It may have been damaged. This problem can be solved in two ways: either update the drivers to latest version, or a few days ago when the keyboard was working.
- If you just purchased a computer and have never used it yet, try going into BIOS - perhaps keyboard support is disabled. In the BIOS menu, you need to find an item called USB Keyboard Support and transfer it from the Disabled to Enabled position.
- In case you are using wireless device(keyboard), which runs on batteries, do not forget to charge it. Probably, it was just discharged, and therefore stopped working.
- And users often complain that the keyboard does not work in games or programs. Fortunately, in most cases, dealing with this problem is easy. The fact is that by default the control is programmed for certain keys, which you can change at your discretion. To do this, you need to go to the game settings. The same fully applies to and.
Finally, I remind you once again that in most cases you can solve the problem with the keyboard yourself. Well, if she still refused to work, then you will have to spend money on buying a new one, because the repair this device usually unreasonably expensive.
Have you ever had a situation when you, while working at a computer, suddenly noticed that the keyboard refuses to type? And it doesn't matter if you text in in social networks or print the most important work in your life: a thesis, a master's degree, or a much more promising professorial one. 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, as before, does not respond. You start to panic. What to do? Call the master or buy a new keyboard? What if it's a laptop? There is an exit!
To eliminate 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 the most common in our time. The USB keyboard uses plug-and-play technology ("plug and play"), so the connection is the most common problem. As soon as the keyboard stops responding, first of all, you need to disconnect it and plug it back into the USB port of your computer device. Perhaps the contacts just went away. Usually, doing this will fix the problem. But it also happens that the failure 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 the device to another device, or at least to a different USB port on your PC. Having done these steps, you can already discard some of the guesswork about why the keyboard does not work on the computer. Windows XP, 7, Linux implement device connection settings in different ways. There is a possibility 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 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 stops working while working on it with the PC turned on, be sure that the problem is in the operating system or software. Perhaps some process is slowing down its work. The main difference between PS / 2 computer keyboard from USB is that if the device fails, you must restart the computer in order for it to work again. After all, this is not a plug-and-play technology.
- Wireless keyboard - modern type input device, but this does not mean that it is without flaws. It may also refuse to work, like other types of devices. You can 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 blocks the USB receiver. In this case, you need to clear the computer table of unnecessary things and see if it works now. In fact, a wireless keyboard is the same USB peripheral, with the only slight difference: there are no wires here. In this regard, it is necessary first of all to check the blocking of the signal. If no changes have occurred, then you must follow the steps described in the paragraph USB computer keyboard.
Troubleshooting through the BIOS
- You have taken the steps to fix the problem mechanically, but, unfortunately, this did not help. Panic sets in. Why doesn't the keyboard on my computer work? Windows 7, first of all, needs to be rebooted. Perhaps the problem will fix itself.
- Try pressing the Esc button a few times to see if the display's auto-start 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 worked, press the F10 key to bring up the BIOS menu. In the settings, you need to set the default values, this is done by pressing the F5 key. Some devices may have other hotkeys.
- After making changes to the BIOS, you must restart the operating system.
- If, after the steps taken, you still have not solved the problem and are wondering why the keyboard on the computer does not work, then you need to reinstall the keyboard software in 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. This is the section we need. Clicking on 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 of hidden devices. So in the new open window we are looking for the necessary item Keyboards and trying to solve the problem of why the keyboard does not work on the computer. Windows 7, 8, XP are slightly different in their interface, so the path to the setup menu may not be the same. When calling the object's control panel, select the option to reinstall and update the hardware configuration and drivers. After rebooting the computer, the hardware should work correctly.
The problem of pressing several characters on the keyboard with one key
Sometimes while typing from the keyboard, a situation arises when the keys stick and print several characters at once. And the problem is not that you press the keys for too long. The whole point is in the keyboard response settings. To change these settings, you must manually enter the word "keyboard" in the search bar in the start menu "Start". A new window will appear before your eyes, when you open it, you should correctly adjust the speed of the delay in 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
Often situations of keyboard failure occur due to incompatibility of drivers on the operating system. Exist different versions"Windows": 32 and 64 bit. How do they differ and why do they need different drivers? The main difference in the processing of different volumes random access memory. That is why it is necessary to install Various types drivers, so as not to panic at the most inopportune moment why the keyboard on the computer does not work. Windows 8, 7, XP, Linux require installation different type software. But to find out if this is the real cause of the problem, you need to restart your computer and look, by pressing the NumLock and CapsLock keyboard keys, to check their operation using the lights on.
2 way to troubleshoot keyboard through CMOS
Another way to check if the keyboard is working outside of the operating system is to go into the CMOS settings and try the keyboard in safe mode. Sometimes the operating system crashes, safe mode will fix this failure. If the CapsLock and NumLock keys fail, you must go to the first method.
The computer device beeps when typing from the keyboard: solutions
Why doesn't the keyboard on my computer work correctly? There are situations when, when working with a character set, a computer device emits sound signals. In this case, you need to change the keyboard settings. To go to the settings, you need to write the word "Keyboard" in the search bar.
In the control panel results that appear, there is an item to change them. You need to follow this link, near the item “Easy typing”, uncheck sticky keys and go to their settings. In the new window that opens, uncheck the box next to Sticky Keys when you press the Shift button five times. We save the results by clicking on the OK button, after which the previous keyboard settings window automatically opens. In it, uncheck the box next to the item of sounding 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 beeps.
Numeric keypad refuses to work
Some users, when buying a peripheral, 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 operating system. Ubuntu system. What to do in this case? Try just pressing a combination of two keys: Shift + Num Lock. Most of the time this helps. There is a possibility that with numeric keypad mouse control configured. To disable it on the Windows operating system, you must press the key combination Alt + Shift + Num Lock. There is another more complicated way to get to the optical mouse settings. But why complicate your life when pressing a keyboard shortcut can solve the whole problem?
Why the keyboard on the computer does not work when turned on: solving the problem
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 connection or signal loss, 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 "Control Panel".
- If it is possible to connect the keyboard to another computer device, check its performance on it. On every operating system software settings are on different paths. You need to know the interface of the operating system well in order to solve the problem of why the keyboard on the computer does not work. Windows 8.1 is arguably the most difficult system to set up software changes. But to change keyboard settings, you don't need much knowledge. It is necessary to strictly follow the instructions, and then your peripheral device will work again as quickly as before.
Possible reasons for the inoperability of some keys on the keyboard
There are times when, due to negligence or negligence, 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 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 most 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 the possible causes of a broken computer keyboard. It will be new to some users to find out that an on-screen keyboard is automatically installed on any operating system. In case of job failure peripheral device she will definitely help you.
Does the laptop keyboard not work? It cannot be said that this is a typical situation for modern technology, this is a fairly rare breakdown of laptops. And if in the case of a PC, you can’t even figure out the cause of the breakdown, simply replacing one keyboard with another, then in the case of a laptop, things are much more complicated, because its keyboard is an integral part of a single integral design. What could be the reasons for the breakdown of the laptop keyboard, what consequences can presumably be expected, how to get out of the situation when you urgently need to enter text on a laptop with a non-working laptop - all these questions will be discussed below.
1. Is there a black list of laptop models prone to keyboard failure?
Before proceeding to a direct consideration of the very problem of laptop keyboard failure, a few words about whether it is possible to prevent the occurrence of such a situation. Is there such a black list of laptops - specific models, products of a specific manufacturer, which would have been proven in practice to be prone to failure of the keyboard? No. On the market computer technology there are no such models for which in practice there would be a tendency to precisely this breakdown. A laptop keyboard from any manufacturer can fail. And this applies to both flagship models and budget ones.
2. Possible causes of laptop keyboard failure
Before you take your laptop to a service center, you can try to figure out why the laptop keyboard is not working on your own. And if it software failure or problems with the keyboard cable, your attempts may be successful, and you will save on services service center. So let's get started.
2.1. Software failure
The reason for the failure of the laptop keyboard may be due to errors in the operation of the operating system itself. Windows systems. As a rule, this happens in the event of a driver failure. You can check this in the BIOS. To exit the BIOS, restart the laptop and hold down the Del key. In some laptop models, the F1 or F2 buttons may be used to enter the BIOS. This point can be clarified in the instructions of the laptop manufacturer. If the keyboard works in the BIOS itself, you can boot Windows in safe mode to further test whether the keyboard works without drivers and with a minimum set of system services.
You can get into safe mode in Windows XP, Vista, 7 using the F8 key, which must be held during system boot. A boot mode selection menu will appear, where you need to select boot in safe mode without drivers. In the case of Windows 8 / 8.1, the exit to the safe mode of the system is somewhat different, some preliminary system settings. Walk the path:
"Control Panel" - "Administration" - "System Configuration".
In the "Downloads" tab, set the value to "Safe Mode", click "Apply", "OK" and reboot. After the reboot, you will be in safe mode.
You can return the settings to their previous state in the same way by removing the "Safe Mode" value.
So, you have entered Windows Safe Mode. Check the performance of the laptop keyboard. If the laptop keyboard works in safe mode, then the problem lies in the drivers. If the keyboard is in safe Windows mode does not work, while the BIOS responds to data input, most likely the problem is in the operating system itself.
After returning to normal mode Windows work work on installing or updating drivers.
Download and install the driverpack. This special type software designed to select drivers for specific hardware components of a computer device. After scanning the laptop and determining the drivers necessary for installation, the driverpacks automatically remove their installers from their database and carry out the installation. Driverpacks on the Internet can be found in a DVD image with an existing driver database, but it is much easier to quickly download and install software client a driverpack that, after scanning, will download from the Internet only the necessary drivers in their latest, most up-to-date version.
DriverPack Solution, Slim Drivers- client programs of these driverpacks can be downloaded on the Internet absolutely free of charge. These are the two leaders among driverpacks, they are popular with users because of the free and regularly updated driver database. Scan the laptop using the driverpack and install (or update) the drivers that the program indicates.
You can install or update drivers without resorting to driverpacks. Download them manually from the official website of the manufacturer of your laptop model.
If the work of installing or updating laptop drivers does not solve the problem with not working keyboard, you can try reinstalling Windows itself. For example, Windows XP - today it is already outdated operating system, and possibly when Windows installation 7 or 8/8.1 keyboard not working issue will go away.
2.2. Pressed or oxidized keyboard cable contacts
If you have been using a laptop for a long time, perhaps the problem of a non-working keyboard lies in the oxidized or pressed contacts of its cable. To test this option and attempt to solve the problem, the laptop will have to be disassembled. If this is your first time disassembling a laptop yourself, use its instructions from the manufacturer. Instructions for many device models can be downloaded on the Internet in electronic form, in particular, on the official website of the same manufacturer. You can also watch video tutorials on how to properly disassemble a laptop on YouTube or other resources.
Having reached the keyboard cable, disconnect it by sticking it out of the connector and carefully examine it. If you see obvious damage during inspection, then this is the reason for the non-working laptop keyboard. And you can solve it by replacing the cable.
If everything is in order with the keyboard cable, wipe its contacts with an ear stick moistened with alcohol, or use a regular eraser. After cleaning, insert the keyboard cable back and test.
2.3. Failure of the microcontroller or liquid spilled on the laptop
If the cause of the non-working laptop keyboard is a burnt microcontroller or spilled liquid, in this case you cannot do without the services of a service center. It is impossible to thoroughly determine which hardware components of a laptop are out of order and solder them at home (of course, if you are not an expert).
When liquid is spilled on a laptop, if it gets on the board, over time this leads to oxidation of the contacts. As a result, the keyboard is completely out of order. If you accidentally spill liquid on your laptop, turn it off immediately, remove the battery, and dry it with a hair dryer on a gentle setting to dry your hair. If your hair dryer has a cold air button, use cold air only. This is necessary in order to, if not prevent, then at least slow down the process of oxidation of contacts, microcircuits and boards.
3. You urgently need to enter text on a laptop with a non-working keyboard - what to do?
The laptop keyboard does not work, and you urgently need to send a message. Or even to download the same driver pack from the Internet, you will need to enter its name into the search engine. How to be in such a situation?
3.1. Windows virtual keyboard
Windows OS has built-in functionality that emulates a physical keyboard - this is a regular On-Screen Keyboard application. Click the "Start" button, select "Ease of Access", and here - "On-Screen Keyboard".
Click the desired keys with the mouse to enter characters. On screen Windows keyboard the "Options" button is implemented, when you click it, you can make some settings to customize the application for yourself.
Windows 8 / 8.1, in addition to the regular On-Screen Keyboard application, has an alternative in a slightly different format. This is a special touch keyboard for tablets and laptops with touch screen- a smoothly moving window with large buttons so that it is convenient to get on them with your finger. If your laptop is running Windows 8/8.1, the panel Windows tasks call the content menu and select "Properties".
The "Taskbar Properties" menu will open, go to the "Toolbars" tab and check the box next to the "Touch Keyboard" option.
3.2. USB keyboard
If we are talking about a high-speed test set, of course, with on-screen keyboard you won't do a lot. You can connect a physical USB keyboard through the laptop's USB port.
3.3. Bluetooth keyboard
Bluetooth keyboard - a physical keyboard that can be connected to a laptop via bluetooth module. Almost all modern laptop models are equipped with this module.
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, the keys stick or does not respond to pressing.
What could be the causes of failure and their solutions
I decided to write an article in the form of paragraphs so that you can go through them and find out why the keyboard does not work.
There is information on the blog when the keyboard in the laptop refused to work: "".
- Novice users usually immediately panic and forget about the most banal things. The very first thing to check is whether the keyboard is connected to the system unit (directly to motherboard).
- Unplug the keyboard for a while (5-10 seconds) and plug it back in.
- If your keyboard suddenly stops working, try restarting your computer. Sometimes restart windows helps.
- It is now very popular to use wireless keyboards and mice. If you have used wired keyboards before and this moment If you have a wireless one, then I remind you that the batteries are discharged, and from time to time you need to recharge them.
- All modern keyboards are connected through a special connector called a USB port. If there is free USB port, then try to connect the keyboard to it. In the event that all ports are busy, turn off the printer or any other device to check the USB port for operability by connecting a keyboard there.
- If you have children at home, then it makes sense to check for extra items, in the connector or in the system unit(motherboard). Once I witnessed a situation when there was paper or chewing gum in the USB port, and therefore the keyboard stopped working.
- It is possible that the keyboard has already worked its way. To check if you have it working, you can go to your neighbors with a request to connect your keyboard to their computer. If the keyboard works, then something is related to your computer. Perhaps you have a spare keyboard, then connect it to your computer.
- If the keyboard does not print only partially, you may not be able to type the numbers that are on the right side of the keyboard. If so, then press the "Num Lock" button.
- What to do, the keyboard does not work, but have you already done all the methods described above? If you have an old-style keyboard called PS / 2 (pis in half), then pay attention to the legs. They may be bent or one of the legs may be missing altogether. These legs can bend when you connect 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 one is the mouse.
- If there are food crumbs in the keyboard, or if you dropped it corny 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 off. When you disassemble the keyboard, you need to touch up and clean the elastic band, if necessary.
Wipe the rubber band with a dry cloth, and the keyboard itself can be wiped with a dampened one.
When disassembling the keyboard, it is important for novice users not to forget 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 picture on a cell phone.
- If USB keyboard does not work, you can see in the BIOS 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 take a PS / 2 keyboard or an adapter from USB to PS / 2. Having connected PS / 2, you can now work with the keyboard. We go into the BIOS and switch USB Keyboard Support to Enabled (Enable). Also, make sure the USB Controller is Enabled.
- Another reason for the failure of the keyboard may be that the driver has 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 fine. Strain 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 Driver Software..."
- If the keyboard came with a CD with drivers when you bought it, 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 reason, you now know. Just in case, go over all the points, you may have missed some of them.
Keys do not work in a program or game
Users who love to play games sometimes encounter the problem when some part of the keys does not work.
If the keyboard works, but after entering the program or some 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, you need to save all changes, 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. The part of the hotkeys that does not suit you, change to the ones you are used to.
If the keyboard does not work for you, and you have tried everything that has been said here, then you can buy the most ordinary keyboard, since their cost is not high.
