Several keys do not work on the laptop. What to do if laptop keyboard doesn't work? Software malfunction

Do you click on 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 the keyboard is typing the wrong letters and symbols, there may be several reasons. I will describe each of them and the 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 FN key pressed, press Fn + Ins (Insert) and try typing. In some cases, Fn + Num Lock should help.

As I said above, pressing the Fn key will activate additional characters attached to buttons. They are usually labeled in a different color and painted on the buttons in the corner.

If you're sure your keyboard doesn't have an Fn button, just read on. There are a few more ways below.

Reason # 2: Sticky Keys is on.

Windows has a Sticky Keys mechanism, it is activated if you press one button or several buttons many times in a row. Very often cats turn on this mode, walking on the keyboard or lying on it.

Disabling Sticky Keys is simple:

1. Go to Start Menu
2. Find the item "Settings"
3. Here "Control Panel"
4. Further "Accessibility" or "Accessibility Center"
5. Search for "Set of keyboard shortcuts one by one" or "Sticky keys"
6. Find the checkbox "Enable Sticky Keys" and uncheck it.

Reason # 3: Crumbs in the keyboard or other rubbish.

Everything is simple here, visually look at the keyboard if crumbs or other debris are visible between the buttons. Flip the keyboard over and shake gently until all or most of the crumbs fall out from under the buttons, then check to see if that helps. Repeat until all buttons work.

Reason # 4: Problems with regional settings.

Check in the menu:

1. 1. Start
   2. Setting up
   3. Control Panel
   4. language and regional standards
   5. Here is the "Languages" tab and click "More"
   6. Then check which keyboards you have, should be Russian and English (US).

Please note that next to the word Russian, there are no postscripts: Mashinny, Ukraine, Belarus, etc. If you had a wrong layout, then delete it and click on the "Add language" or "Add keyboard layout" button. Then choose the correct Russian, no postscripts.

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 press. If so, please check your computer for viruses and make sure that the correct Russian layout has been added just in case. It will not be superfluous to delete it and add it again, just in case. If, on the English layout, the discrepancy between what you press and what appears on the screen continues, then you have a problem with the keyboard itself and it needs to be replaced. This often happens when liquid gets on the keyboard.

Good times of the day!

If there are no problems with a regular keyboard for a PC - it broke down, I bought a new one, but with laptops it is not so simple:

• firstly, in some cases it is quite difficult to find it;
• secondly, it is not easy to change it yourself (sometimes you need to disassemble the entire device);
• thirdly, the inoperability of some keys is not always associated with a malfunction (but on this many users get burned ...)!
• fourthly, the laptop keyboard often "bites" at the price (it costs much more).

Actually, in this article I want to give some not entirely obvious reasons due to which the keys may stop working. In addition, it is not always worthwhile to immediately run for a new keyboard - agree, if 1-2 keys do not work for you (which are not so often used), then it is quite possible to do without them?

In general, in this article I will give different options for reasons, solutions, and what you can do if you encounter this problem. So...

Keyboard performance testing (diagnostics using the Keyboard test utility) -

Are the keys disabled in BIOS (relevant for FN, F1 ÷ F12)

If the function keys (F1 ÷ F12) do not work for you, or special. FN key - it is possible that the problem lies not in the keys themselves, but in bIOS settings (UEFI). By the way, I note that by default on many laptops the function keys are disabled. (great functions are performed instead: volume up, Wi-Fi on / off, screen brightness, etc.) .

As a rule, you need to enter the BIOS and change the operating mode of the functional. keys (the parameter name is something like "Hotkey Mode", as in the screenshot below).

In addition, pay attention to whether you have installed drivers and specialized software from your laptop manufacturer. For automatic update For a long time, I've recommended this list of utilities for drivers:

Why Fn and function keys F1 ÷ F12 may not work on a laptop (solution to the problem) -

By the way, if you have a regular PC keyboard, then pay attention to the special keys F Lock or F Mode (eg). They are not very common, but still ...

Using them, you can disable the function keys (next to them, there is usually an LED, example below).

F Lock key (most often found on expensive keyboards)

Garbage under the keys (dust, crumbs, hair)

The most common cause of poor response on most keys is debris and dust that accumulates underneath over time. Characteristic feature in this case: when pressed lightly, the key does not work, however, when pressed with some effort, the key works. Although, of course, a lot depends on the design of the keyboard itself (some are specially protected, and in general they do not have such a problem).

How can you clean your keyboard:

Wear and acidification of tracks (especially important when flooding the keyboard)

For reference! Conventionally, keyboards can be "divided" into 2 camps: membrane (in which thin films with tracks are used), and mechanical (where each separate button is a "button"). The most common keyboards are membrane (about 90% -95% on the market). They are cheaper and lighter (which is especially true for laptops).

So, whatever the keyboard is - it is designed for a certain amount of clicks (as a rule, several tens of thousands - this is several years, even with active use). Over time, the conductive tracks acidify, the thin contacts closing the tracks wear out, and the dust also does its job.

By the way! The process of "acidification" of conductive paths is accelerated hundreds of times if you spill some liquid on the keyboard. Which, by the way, is not so rare, experts abroad considered that every 100th circle above the keyboard falls over on it ...

Membrane keyboard (as an example, so that it is clear what is at stake).

In case of problems with the old keyboard (or with some kind of liquid filled in) I can advise the following recipe (he does not guarantee recovery, and you do everything on it at your own peril and risk. However, to revive several keyboards for a while, he helped me) :

How to do without some buttons

It is far from always possible to replace the keyboard: sometimes there is no money, quite often many get so used to their keyboard that they simply do not want to change it to any other. As for laptops, it may become so that the right keyboard for your model may not be found ...

But in many cases, you can do without non-working keys (especially if there are only 1 ÷ 2). The most popular ways of this "workaround" are given below ...

You can reassign one key to another

The most common option is to use special utilities that can replace pressing one key by pressing another. It sounds a little "strange", but the principle is:

• for example, the "Z" key does not work for you;
• you set the "Ctrl" key together with it;
• now when you press "Ctrl" - you will trigger "Z" (note that you can reassign almost any buttons to each other).

How to reassign one key to another (for those who do not have a button press on the keyboard) -

I am personally impressed by the MapKeyboard utility - simple, free, reliable. The principle of working with it is very simple: first, indicate which button you want to use instead of the disabled one; then indicate not working and save the settings. After rebooting the PC / laptop - the "job" is done, the key will be replaced (the screen is just above).

You can connect an additional keyboard

Just like with a PC, you can connect a regular keyboard to any laptop (most often a classic USB keyboard is used). As a rule, there are no problems with configuration: the keyboard becomes available for operation immediately after connection.

You can use the virtual keyboard

Not everyone knows that Windows has a virtual (software) keyboard that you can click with the mouse cursor. Something like the one that appears on Android deviceswhen you refer to some text block.

To cause such virtual keyboard, Windows, and go to the next section: Control Panel \\ Accessibility \\ Ease of Access Center ... There will be a link to launch it (see the screen below).

The keyboard looks pretty good, the buttons are large and comfortable. It can be quite used when filling in small text fields when the main keyboard does not allow it.

If the problem is with the power button

Not so long ago, by the way, I received an interesting question about a non-working power button on a laptop. In general, it does not directly apply to the keyboard, but nevertheless ... I decided to indicate it too in this article.

How to turn on a laptop without a power button, is it possible -

Additions and comments on the topic are welcome ...

Happy work.

A keyboard is a set of keys arranged in a certain order that allows you to control a particular device, which in our case is a laptop. In addition, the keyboard is one of the main input devices. Of course, for tablets and smartphones it is not required, however, it is impossible to fully use a PC or the same laptop without it.

I already talked about why it might be. Today we will talk about a laptop keyboard.

Software glitch

It's worth starting with the most common problem that you can solve yourself. In this case, I want to consider a software glitch.

What does it look like? You just turn on your laptop after some idle time and realize the keyboard isn't working. The first thing to do is not to panic, as some people like to do. It is quite possible that the problem is trivial and it can be solved in one minute.

The first step is to restart your laptop. You can do this with the mouse or. We reboot the device or, if you wish, turn it off and turn it on again. I assure you that 60% of the keyboard will work again after a restart. It's all about a certain software glitch, which may have occurred during the boot phase of the operating system. If this method helped you, then you may not even read the article further.

If it doesn't help, then we reboot the device again and as soon as it starts loading, we try. To do this, you need to press the TAB key, and if it does not help, then F10 or DEL. One of these options should definitely work. If you managed to do this, then physically the keyboard works and this suggests that the problem is 99% not mechanical.

You need to exit the BIOS and boot the device. Most likely the keyboard won't work, but don't worry, we'll try to get it to do it. For this, it will be necessary at the time when it was in working order. I have already described how to do this on the pages of the site. Rolling back to an earlier date should help.

In some cases, you can reinstall operating system, but this, you understand, is not the most pleasant process, along with which, by the way, you can delete important information.

About drivers

Some device problems are directly related to drivers. They may, for example, be completely missing or damaged. In cases with a laptop, this moment is very relevant, since almost for each component you need to install its own driver.

Find the name of your laptop model on the case, then go to the manufacturer's website and find the drivers for the specified model. Among them, there should definitely be drivers for the keyboard. Download and install them. It is very likely that the keyboard will work after this procedure.

The problem is in the hardware

If none of the above helps, then the problem may be hardware related. Most often, the plume suffers. As the guys who have already disassembled laptops assure, getting to the loop is not a problem, besides, you can find manuals on how to do this on the network. But before you start disassembling your device, remember if it is covered by the warranty. If so, you cannot disassemble it! Take your laptop to the store where you bought it with your receipt and return it for repair (free of course). In some cases, stores find it easier to exchange a laptop for a new one than to repair it.

Let's say that you disassemble the case and get to the loop. What's next? And then you need to carefully examine it for oxidation or damage. If there are no external signs of damage, then wipe it with an eraser. I do not recommend using alcohol and other liquids, as this can adversely affect the performance of the loop.

You put your laptop together, turn it on and test the keyboard.

Dirt and dust

Do not forget about dirt and dust, which are very fond of accumulating under the keys. Oddly enough, the keyboard may not work for this very reason. What to do? As one option, you can remove all the keys (some models can easily do this), remove all the dirt and wipe the contacts with an eraser. If you spend this procedure impossible, you will have to disassemble the device to get to the keyboard, and this is not so easy to do, since you will have to disassemble a good half of the laptop.

If the keyboard does not work due to spilled liquid

What a sin to conceal - the laptop seems to attract liquids to itself, because almost every one of us who has this device has invariably spilled this or that liquid on it. If for an ordinary computer keyboard this most often ends asymptomatically, then for a laptop this is almost a fatal case.

If you spill something on the keyboard, you urgently need to turn off the laptop, remove the battery from it and turn the gadget so that the liquid spills out of it.

Then you need to disassemble the device. Whether it is worth doing this if it is under warranty is up to you, but this is definitely not warranty case, so no one will repair your laptop for free.

If you do disassemble the device, then put it in a dry place. It is best to dry at room temperature without using the "air" technique in the form of a hair dryer. You need to dry your laptop for at least one to two weeks - be patient. Only then can you collect it and turn it on.

Mechanical problems

Mechanical problems are usually associated with the fall of the laptop or when something heavy falls on it. In this case, both one button and several buttons may not work. Less commonly, the entire keyboard. Most likely, only its replacement will help, and it is not so easy to do it yourself, so I recommend contacting a specialized service for help.

The same applies to those cases when the keyboard does not show any signs of life at all, no matter what you do with it.

When the keys do not work on a packard bell, acer, asus, toshiba, Lenovo, Samsumg, or HP laptop, the situation is not very pleasant for Compaq.

Usually the first thing that comes to mind is to refer it to service center... But don't be in a hurry. There are many things you can fix yourself.

It is very bad when some of the function keys on a laptop (packard bell, acer, asus, toshiba, Lenovo, Samsumg HP - Compaq) do not work due to faulty tracks.

You can draw them yourself, only this work is delicate and not everyone can do it.

In almost every laptop (modern) (keys) you can disassemble and see what's what.

It is not worth disassembling the laptop completely, the keys can be removed one by one. Good way removing the keys, my son (2 years old) prompted me - with a fly swatter.

After hitting the keyboard, six keys jumped out of their sockets on their own, and remained completely intact. Only I would not recommend using this method.

Some keys will not work if dust gets under them. In this case, you need to clean it. You can try to blow (without removing) with a strong pressure of air, but usually this does not help - you will have to remove it.

Typically, the keys on a laptop consist of three elements: a platform, an elevator and a spring element and are connected by latches.

If they can be easily lifted with a thin screwdriver, they can be removed. After that, clean the platform and install it back. There is no difficulty in this - it is available to everyone, you can not be afraid.

The situation is much worse if the keys were covered with liquid that damaged the tracks - most will have to send their laptop for repair.

If one or several keys do not work, with the impossibility of self-restoring, then their functions can be assigned to others that are practically not used. Yes, it's inconvenient, but you can use it for a while.

Remember, if some keys on a laptop do not work, then any of them, you can assign absolutely any function yourself.

This can be done in manual mode changing the case (it's so difficult and not everyone can do it) or use a simpler method by downloading a special AutoHotkey program.

This program is not the only one, but if it exists, then others will not be needed. On the right side there are keys that are rarely used, and most of them do not pay attention to them at all.

Assign the missing functions to them, apply stickers with the designation (so as not to be mistaken) and use them until you decide what to do with the keyboard in the future.

• By the way, there is still online services and special programs with which you can check (test) the keyboard for errors. You can download the program or use online resources

Also keep in mind that keyboards are not expensive, one might say, they cost a penny, and you can easily connect an external keyboard to a laptop or netbook, and not just replace it. It's just inconvenient to take it with you.

When not working on a laptop, there is another way to solve the problem - to use a virtual one.

To call the virtual keyboard, click "start" (Windows logo, at the very bottom left), then find and click "all programs" at the bottom, scroll down the menu to the very bottom and select "standard", then go down even lower and click "accessibility"

After that, finding a virtual keyboard and launching it will not be difficult. For those who write little (only in Yandex or Google), this option can be used even on an ongoing basis.

Anyway, now you know what to do when the keys do not work on a packard bell, acer, asus, toshiba, Lenovo, Samsumg or HP - Compaq laptop.

In this article, we have to figure out an important question: why does the keyboard not type? This phenomenon is not as rare as we would like. But you should not be afraid of him. Problems with are resolved without too many problems. And only in some situations is it necessary to try hard to establish the functioning of the computer component. But for what reasons can the keyboard refuse to work? And what to do in this or that case?

Damaged connector

The first case is not very common, but it does occur. Especially on older computers. For laptops, this layout is relevant only when it comes to a separately connected keyboard.

What is it about? Why isn't the keyboard typing? The problem may lie in the equipment connection connector. It sometimes breaks or gets damaged. In this situation, the keyboard cannot be connected. If using an old model (PS / 2 socket), it is advisable to change the hardware to USB. Or connect the device to another connector. You can also try to fix the jacks. But this technique will not give a long-term guarantee of the device's operation.

Drivers

Why isn't the keyboard typing? The next, already more common reason, is the lack of drivers for. Especially when it comes to multifunctional, with a large number of additional buttons. If the device refused to work, it is recommended to first reinstall the drivers for it. Or update them.

Typically, keyboards come with a CD with the appropriate software. Further And if the reason lay precisely in the drivers, then everything starts working. You can optionally turn off and on the device after logging into the operating system. But everything is not always as simple as it seems. After all, a computer is a device that can present a variety of surprises. And it's not always easy to fix them. So what other scenarios can be identified?

Clogging

Why isn't the keyboard typing? Sooner or later, this question begins to worry almost every user. This is especially true for those who do not monitor the computer and its components at all. The keyboard won't print some letters? What to do? If we are talking about a device that has worked properly for at least a month, we can only recommend one thing - to clean the component.

The keyboard is a clogging device. Dust, food debris, crumbs - it all stays between the buttons. And we are talking about laptops, and about stationary computers... Therefore, all keyboards need to be cleaned from time to time. At least once a year. Or as needed. It is also recommended not to eat in front of the monitor. This technique will allow you not to clog the connected device once again. By the way, this problem is the most common scenario.

Now it is clear why the keyboard does not print. You should only pay attention to the fact that you should not clean yourself. Especially when it comes to a novice user. And even more so, it is not recommended to clean the keyboard from the laptop yourself. Better to take the input device to a service center. Keyboard cleaning services are offered almost everywhere. In just a few hours, you can fix the problem that overtook the user. After cleaning, the keyboard will work at full strength.

Permutation

But these are not all options for the development of events. Sometimes it happens that the keyboard is typing the wrong letters. And in this situation it is very difficult to find an explanation for what is happening. After all, in fact, the device works. It's just not how it should be. There is only one reason why letters print numbers or not what is needed. This is an incorrect assembly of the device. If you take apart the keyboard, you will notice that each button has its own mechanism. The computer receives a signal from a certain key and prints this or that character. For the convenience of the user, these mechanisms are signed as buttons on the keyboard. If the latter are reversed, it appears that the machine is printing the wrong characters.

Therefore, in this situation there is only one solution - to correctly assemble the keyboard. That is, place the mechanisms under each key in the desired order. It is very problematic to do this on your own. Therefore, it is best to take the gadget to a service center. If you don't want to think once again why the keyboard does not print, you should not wipe and wash this component on your own. Often, the problem with the wrong arrangement of buttons happens after self-cleaning. Not the most dangerous, but also not a very pleasant moment.

Incorrect assembly

Keyboard buttons not working? How to be? First, don't panic. Secondly, analyze your last actions with this device. In most cases, the user himself becomes the culprit of problems with the components connected to the computer. What to do if If the user tried to figure out the device on his own, it is recommended to immediately take it to the service center.

The reason is incorrect assembly of the input device. Most likely, when the user tried to assemble the keyboard, an important contact went away somewhere. This is a common occurrence to be aware of. Eliminate this problem you can do it yourself. But users point out that the keyboard will not work in inept hands. Unless it will be completely broken. And the craftsmen usually get it right the first time and disassemble the device and assemble it so that it works fully and without interruption.

Marriage

What if the keyboard does not print? Much depends on the situation. If we are not talking about a new device, then the above options for the development of events may well be the reason for the refusal of the component from work. But what about when the conversation is about the keyboard you just bought? If all the drivers have been installed, the problem most likely has only one reason - a marriage. And here only a complete replacement of the keyboard will help. It is recommended that you immediately contact the store where the device was purchased. There it will be possible to exchange. Otherwise, you will have to buy a new gadget.

Incompatibility

What if the keyboard doesn't work? It is required to find out why the connected device refused to perform its functions. In fact, only in rare cases are serious accidents caused by users. More often than not, all problems can be solved by yourself.

Why isn't the keyboard typing? The whole point may be in the incompatibility of the device with the operating system. This problem has appeared quite recently. Most often, it is encountered by users with Windows 10. With this operating system, old models of this problem are not observed. Yes, the keyboard also has its minimum requirements. And you should pay attention to them. Because you will either have to change the device in the end, or reinstall the operating system to one that is compatible with the gadget.

Viruses

Keyboard buttons not working? This device refused to work at all? If all of the above cases do not fit, you might think about the last, rarest scenario - an infection of the operating system. Viruses are the main enemies of the stable operation of computers. They can affect not only software, but also connected devices. For example, under their negative influence the keyboard either does not type, or displays the wrong characters, or it even puts down several letters / numbers at a time.

There are two ways out: reinstalling the operating system from scratch or disinfecting the computer from the corresponding infection. In the first case, you will have to completely format hDD, only then reinstall the OS. And the second option, as a rule, is not effective enough. For this reason, it is recommended that you save all data and reinstall the operating system on your computer. So the virus will disappear 100%.
