If you turn on the computer and the keyboard does not work, does not respond to key presses and the indicators do not light up, then there can be only two errors: a hardware malfunction or a software failure.

What to do if the keyboard does not work due to a hardware failure

There are very few hardware problems that can lead to a keyboard failure. Usually this is a lack of contact in the connector (the plug is not fully inserted into the connector), a malfunction of the input device itself, and a malfunction of the motherboard port.

First of all, you need to make sure that the keyboard is connected correctly, especially for keyboards with a PS/2 connector. The keyboard has a plug purple and it must be connected to the connector of the same color in system unit. The plug may not be fully inserted into the connector, resulting in loss of contact. You should check this point, or better yet, disconnect and reconnect the keyboard. After all the manipulations, try restarting your computer. It often happens that some kind of software glitch occurs during device initialization. A reboot usually solves such problems.

To make sure that the keyboard is working properly, as well as the port for connecting it, you will need to find another working keyboard. If a known-good keyboard on your computer works fine, then the problem is with the input device itself. In this case, you will have to go to the store for new keyboard. If an initially working keyboard does not work on your computer, but yours, on the contrary, functions normally on another computer, then there is probably a defect in the motherboard. Correcting this malfunction without computer diagnostics is problematic, so it is better to contact specialists. Also, do not forget that you may still have software error, which we will discuss below.

What to do if the keyboard does not work due to software

A software malfunction usually consists of incorrect operation drivers. It is possible to eliminate this problem provided that the mouse is “in service”.

Go to the Start menu and then Control Panel. Here, open the “System” section and launch “Device Manager”. If there is a problem with the drivers, then next to the keyboard in the list there will be a yellow triangle with an exclamation mark.

Click right click mouse on this line and open “Properties”. Now go to the Driver tab and click the Uninstall button. Confirm your actions and the keyboard driver will be removed from the system.

Now you should update the hardware configuration and search for connected devices. To do this, go to the “Action” menu of Device Manager and click “Update hardware configuration”.

The system will detect a new device (keyboard) and reinstall drivers for it. If you are using a multimedia keyboard, you may need to install drivers from the disk for it to work properly. This disc is usually included in the kit. It must first be installed in the drive optical disks and when prompted by the Add New Hardware Wizard, specify the path to the disk for installing drivers. If the installation is successful, the lights on the keyboard will light up. LED indicators. When the Found New Hardware Wizard finishes, you will need to restart your computer for the changes to take effect.

User question...

Hello.

Help with one problem. Out of the blue the keyboard on my Lenovo laptop B70-80. The laptop did not hit, did not flood, did not hit - just after turning it on, it did not respond to pressing some keys. What can be done?

Good day!

What is good in this regard regular computer- so this is a quick change from one keyboard to another. Unfortunately, this procedure cannot be accomplished so quickly on a laptop.

In general, for the keyboard to stop working for no reason is an extremely rare case. Most often, the user guesses what the reason is (and sometimes remains silent). For example, quite often the keyboard is flooded with tea, water, juice; mechanical damage etc.

In this article, I will look at the main reasons why the keyboard fails to work, and what can be done to restore the device’s functionality. So...

The keyboard on the laptop failed: reasons

What can be done to temporarily correct the situation?

I would like to start the article with what temporary measures can be taken in order to at least somehow type some characters, press required keys(which may be needed in the process of restoring functionality).

Method No. 1- connect a USB keyboard. So that any modern laptop has several USB ports. By the way, if the USB ports also do not work, then this is a rather bad sign and may indicate a faulty motherboard. fee;
Method No. 2- call on-screen keyboard. It is located in the section: control Panel/ Special abilities/Ease of Access Center (see screenshot below).

1) User inattention/ignorance

No matter how funny it may sound, very often the keyboard “does not work” due to the user’s ignorance. For example, how many times have people complained to me that the numbers on the keyboard are broken, that dates cannot be entered, etc. - but the fact is that the numeric keypad works when the key is pressed Num Luck(by the way, there is often an LED on it or above it).

So, if this key is not pressed, when you try to enter numbers from the numeric keypad, your cursor will jump, move, and not respond at all.

If numbers don't work for you, be sure to pay attention to this key!

Note: some laptop models include numeric keypad only by pressing the key combination: Fn+ Num Lock.

By the way, one more point: regarding the function keys (F1, F2, F,3... F12). On modern laptops In order for any of these keys to work, you also need to press the FN key. Usually, this moment is configured in the BIOS.

The screenshot below shows the "Advanced" section Dell laptop- in the "Function Key Behavior" item - you can choose how the function keys will work: in the mode of multimedia buttons (turn down/increase volume, brightness, etc.), or in the mode of regular functions (refresh the page, call help, etc.). d.).

I won’t go into detail here on how to enter the BIOS and how to configure it, but I will provide a couple of links to articles from which you can glean this information:

how to enter BIOS -
buttons to enter BIOS for different manufacturers laptops -
how to reset BIOS settings -

2) Debris under/between the keys

Dust, dirt, crumbs love to accumulate under the keys of the keyboard, and in general, the keyboard gets greasy over time from greasy hands and fingers, even for fairly neat users. Over time, some of the keys (usually starting with 1-2) stop responding normally, and you have to press and press hard on them.

An article about how to clean your laptop/PC from dust. Link to the section of the article about how to clean the keyboard from crumbs, greasy marks and dust -

There are three ways to clean the keyboard (in my opinion):

use special A USB vacuum cleaner that can accurately and carefully collect most of the crumbs from the surface of the keyboard;
use special Velcro, which when you press them fill the plane of the keyboard, and when you unhook them, all the dust and dirt remains on them;
You can blow off the keyboard using a regular vacuum cleaner (especially if it has a reverse mode), and then gently wipe it with a damp cloth soaked in soapy water.

3) Software glitch, error loading OS

If not a single key on your keyboard works at all (and you didn’t flood it, didn’t knock, etc.), then I hasten to assure you that in more than half of the cases the software is to blame. For example, a driver conflict might occur during the loading stage of your OS, or you might have picked up some kind of virus, etc.

The easiest and surest way is to try rebooting your laptop first. It would be a good idea to try entering the BIOS (how to do this, see this article:).

Note: if your keyboard works in the BIOS (and the fact that you entered it already indicates this) - then the problem is probably in the software. In case of hardware problems, the keyboard will not work anywhere: neither in the BIOS, nor in Windows, nor in any other OS!

If after rebooting the laptop the keyboard does not work again (and the keyboard worked in the BIOS), try rolling back the system to the state when it worked. Below is a link to an article on restoring Windows.

How to restore Windows 10 -

If recovery doesn't help (or you don't have control points for recovery) you can try. I also recommend paying attention to the drivers, more about them below...

4) Problem with drivers

In general, usually, keyboard drivers are installed automatically when Windows installations. But sometimes the following problems occur with them:

Some laptops have several standard keyboard with additional functions - and for its full operation, special ones are required. drivers. If they are absent, the keyboard may not work in full mode;
There could be a driver failure/conflict in the system. This often happens with USB drivers, TV tuner drivers, audio drivers, etc.;
The keyboard drivers themselves may have been damaged.

- how to delete any old or extra driver in system:

- programs for working with drivers: search, update, removal:

5) Acidification of the keyboard cable contacts // damage to the cable

If the previous steps did not help, and the laptop keyboard also does not respond to any of your presses, I recommend checking the cable. The following usually happens to him:

if you disassembled the laptop and disconnected/connected the keyboard, it is quite possible that the cable could simply not be inserted tightly into the socket. If this is the case, try reconnecting the keyboard;
it is also often damaged when the laptop is not carefully disassembled (the wires in the cable are quite thin and can be broken with one careless movement);
the contacts of the cable, or the socket in which it “sits” could oxidize over time and not give good contact. Try to gently wipe them with an eraser (as a rule, the contacts begin to become lighter even by eye, which means you have removed the oxidized coating).

IMPORTANT! On some laptop models, it is far from easy to remove the keyboard: to do this, you may sometimes need to disassemble the entire device to the ground! In general, it is usually enough to unfasten several latches with a screwdriver (see photo above) and lift the keyboard plane.

By the way, if your laptop is under warranty, use the service center. Your independent disassembly (including disconnecting only the keyboard) will almost certainly cause a refusal of warranty service!

6) Keyboard flooded with liquid

Some specialists failed interesting statistics: every 50th mug over the laptop tips over onto it. In this case, it is the keyboard that suffers first of all. By the way, from my own experience I will say that in case of any spill, the keyboard suffers 100%, but the rest of the devices (underneath it) still have a chance to remain dry: it all depends on the speed of the user’s reaction after the incident, and the amount of liquid spilled.

In general, liquid is different. Liquids containing salt or sugar are especially dangerous for iron: tea, juice, lemonade, etc. When such a liquid gets on the contacts and metal parts of the boards, the process of oxidation and corrosion begins, which destroys (in some cases not immediately, but surely) iron.

What to do if your laptop is flooded:

turn off the laptop: you can immediately disconnect the power supply and remove the battery as soon as possible (the sooner the better);
then turn the device over so that liquid begins to flow out of it;
dry the device for several days (before this, the device simply will not dry). Do not use hair dryers, heaters, or other similar devices for drying;
It is highly advisable to disassemble the device and see how far the liquid has penetrated. In general, of course, if you have never done this yourself, I recommend showing the device to a service center: because even if your device works after drying, the remaining liquid (especially if it was aggressive: juice, beer, tea, etc.) will slowly and surely destroy your iron from the inside, causing corrosion and oxidation.

7) Mechanical damage

In general, by and large, there is nothing to break in the keyboard, and as a rule, the breakdown is associated with damage to a specific key (i.e., 1-2 keys will no longer be pressed). Typically, this happens if something fell on the laptop keyboard, or you accidentally touched the device (this, for example, could happen on the road, when moving the device).

In some cases, when the contacts on the keyboard board are damaged (or the button is “clamped”), the keyboard may not respond to pressing other keys and may not behave stable. By the way, you can find out if you have any key pressed if you open some text editor: Word, Notepad, etc.

Button "a" is frozen

By the way, if 1-2 keys do not work for you, then you can reassign to others and use the keyboard for a while (or maybe this time will be long?!).

To help! How to reassign one key to another (for those who cannot press a button on the keyboard) -

8) What about the laptop battery?

And the last thing I would like to dwell on in this article. In general, this is quite rare, but I still saw it on one “no name” Chinese laptop: the keyboard on it stopped working if the battery was low and below a certain minimum of 7%, apparently some kind of software was working (I hope such software will not become popular?) .

This concludes my opus, for additions on the topic - thank you in advance. Good luck!

What to do if the washing machine does not respond to pressing the button? In the article we will give step by step instructions, we’ll tell you whether you can repair or replace the buttons yourself.

The electronics of a washing machine are the most vulnerable part. This applies to the control panel and the buttons on it. The keys are constantly exposed to the user, powder and rinse aid get on them, which leads to failure of operation.

How to determine the cause of a malfunction based on external signs:

The start button does not turn on. When pressed, the machine does not react at all.
Pressing the "Start" button causes the LED to light up, then nothing happens.
When you select the On/Off button, all lights begin to flash.

Why the buttons don't work:

Strong pressure on the buttons causes them to become stuck over time.
The cause of the breakdown may be detergent that gets on the panel. As a result, the keys get stuck.
Contacts leading from electronic board to the buttons.

Note! If after purchasing and installing the washing machine the power button does not work, the reason is a manufacturing defect. Contact service under warranty.

Most often, buttons that are subject to frequent impact break. These are the Start, Pause, and program selection buttons. The rotary selector also fails.

Troubleshooting and troubleshooting

Before looking for the cause of the malfunction, disconnect the machine from the network and communications. Start checking from the very beginning simple element, which does not require disassembling the machine.

Voltage problems

It happens that you try to start the washing machine, but nothing works. It is not necessary to contact the service immediately; your electricity may be turned off. In this case, you just need to wait for it to resume.

There are also power surges in the network itself. If the voltage level is too low or, on the contrary, exceeds 220 Volts, then the washing machine will not work. To check your guess, take a multimeter and set the toggle switch to voltage measurement mode. Attach one probe to the COM socket in the socket, the other to the VΩmA socket.

Keep in mind! Network problems may occur if your neighbors use high-power equipment.

If you find problems with the network, then you will need the help of an electrician.

Extension cord faulty

Carefully inspect the wiring for any burns or melted plastic. If everything is in order outwardly, connect another device (lamp, charger) through the extension cord and check its operation. If the device does not work, replace the adapter.

Hatch lock unlocked

If the hatch door lock is not locked, the wash will not start, as there is a risk of water leakage. Try pressing the door tighter - if it doesn’t come out, the lock may be broken. In this case, check the hole into which the lock tongue fits. Perhaps there is debris clogged up there.

Also check the lock itself:

Open the door.
Unscrew the two bolts that secure the UBL lock.
Bend the sealing rubber of the hatch and remove the clamp.
Putting your hand behind the body, remove the lock and disconnect the wiring.

You can check the lock using a multimeter. We wrote more about this in previous articles. If there is a malfunction, the part cannot be repaired; a complete replacement is required.

Noise filter does not work

Since the washing machine is a powerful device, its design includes an FPS filter that suppresses interference. Thanks to it, other appliances in the kitchen (TV, radio) do not experience interference.

You can check the functionality of the filter like this:

The power button on the washing machine does not work

From the noise filter, the wiring leads directly to the “Start” button. Without closing top cover, check the button contacts. If there is no external damage, use a multimeter to test two wires - phase and zero. To do this, turn on the button to understand whether it connects the contact or not.

This wiring arrangement - from the filter to the "Start" button - is typical for early brands of washing machines. IN modern models The wiring leads directly to the control module. Therefore, the electronic unit is checked next.

Control board faulty

Checking the command apparatus is not an easy task. It's better not to do this on your own. All elements and contacts of the board are checked with a multimeter in a certain order. Therefore, if you suspect that it is broken, contact the service center.

The machine does not respond at all to button presses

What if on the panel, except for the “On/Off” button, not a single key works? Are all the buttons broken? No. Most likely, “Child Protection” was installed.

Disconnecting the machine from the network will not help remove the lock. You need to simultaneously press the “Spin” and “Function” keys. Make sure the lock no longer appears on the display.

What to do if the sensor does not work

If they don't work touch buttons on the panels of Ariston, LG and other models of washing machines, then they need a complete replacement. Buy touchpad You can separately install it in place of the old one.

Most often, sensors fail due to high humidity in the room or when exposed to liquid detergents. It is advisable not to install such equipment in the bathroom, since the electronics are very “delicate”.

How to replace washing machine buttons

Is it possible to replace the washing machine buttons yourself, or do you have to call a professional? The answer is clear - you can. Proceed sequentially:

Before starting work, turn off washing machine from the network.
You need to remove the dispenser tray. Pull it towards you while pressing the latch in the center.
After unscrewing the screws from the back, move the top cover away from you and set it aside.
Unscrew the screws that are located behind the dispenser tray.
If there are screws on the other side of the panel, remove them.
Release the plastic latches using a flathead screwdriver.
Before disconnecting the wiring, take a photo of the location of the connectors. This way you can connect them correctly.
By removing the panel from the case, you will see its components. This is the panel body and the control unit, which is secured with latches.
Unlock the latches and set the control board aside.
Now you can see the buttons.
All keys and the selector are removed by simply pressing from the outside, so changing them is not difficult. The design is very simple; in operation, the buttons simply press on certain areas of the board. Therefore, the board must be checked.

After removing the old elements, proceed to install new ones. To do this, you only need your hands and a screwdriver. The electronics module is then placed in place, the latches are snapped into place, and the wiring is connected.

If during disassembly you find that debris, powder, or gel have gotten into the button connectors, try cleaning them and checking them again. You may not have to purchase new parts.

Is it necessary to repair the control panel?

Before you repair the panel, you wonder: is it necessary to change all the elements because of one button? The question is which key is not functional.

If the start button does not work, you will not be able to start the washing program - repair is required.
The rotary selector does not work - it will not be possible to switch the program and wash certain types of items. And if the temperature switch is broken, the quality of the wash will drop sharply.

Of course, if the button is faulty and is rarely used or not used at all, then you can try to continue using the washing machine. However, this is dangerous. After all, the reason may be a malfunction of a section of the module or contacts. Therefore, it is recommended not to delay repairs.

In some cases, the self-diagnosis system of the washing machine may display a fault code on the display. For example, if a module breaks down. Then you need to take appropriate measures.

Replacing the buttons on the panel is not difficult with your own hands. But when it comes to electronics, use the services of professionals.

A locked keyboard on a laptop is a real problem. The laptop does not respond at all to key presses or responds randomly to pressing some symbols or numbers. A locked keyboard makes it impossible to use the device - it is impossible to enter an address into address bar browser, reply to email, type text in text editor. Unfortunately, the question of how to unlock the keyboard on a laptop does not have a clear answer. The options for action in this situation differ depending on the laptop model and manufacturer, and also depend on the situation that led to the blocking. You can still take some steps yourself to unlock the keyboard on your laptop without contacting specialists.

The keyboard may have stopped working as it should as a result of pressing the Num Lock, Caps Lock, Scroll Lock function keys. It is necessary to check whether the corresponding indicator lights. Very often, users accidentally press these keys without intending to switch to another keyboard mode. For example, the Num Lock key on laptop keyboards rearranges some of the letter keys and replaces the “U”, “I”, “O” keys with the numbers “4”, “5”, “6”, the “J”, “K” keys, “ L" with the numbers "1", "2", "3" and so on in a similar manner. You need to turn off the Num Lock, Caps Lock, Scroll Lock indicator lights by pressing the corresponding key on the keyboard. Sometimes you additionally need to hold down the Fn button. It depends on the laptop model. Now all that remains is to check the keyboard, perhaps it works normally again.

It happens that the keyboard stops working as expected as a result of accidentally turning on special features that are provided in operating systems Windows family. To turn off such settings, click Start => Settings => Control Panel. In Control Panel, open the Ease of Access window. On the Keyboard tab, clear the check mark next to each custom setting option. Click OK. Check if the keyboard is working properly. Special Settings affect the performance of the keyboard and may cause the keyboard to feel locked.

You can try to return it normal work keyboard by removing the laptop battery. Close all running programs on the laptop. Since the keyboard is locked, use a mouse or touchpad to complete this task. Then turn off the laptop and close it. Now you can disconnect the adapter alternating current(if it was connected) and turn the laptop over to remove the battery. If necessary, you can see how this is done in the instructions for the laptop. After two to three minutes, you can reinstall the battery by placing it back in the battery compartment. Next, turn on the power to the laptop and check the operation of the keyboard.

Unlocking the touchpad is easier. Often, while working, you have to lock and unlock the touchpad. This is due to the fact that while typing on a “tight” laptop keyboard, it is easy to catch the touchpad and this will lead to unplanned changes in the text. Typically, the touchpad can be locked and unlocked by pressing the Fn+F6 key combination (Fn+F7, Fn+F12, Fn+F9, or similar). Number function key, pressed together with the Fn key is different for different models. Refer to your laptop's user manual for information about the required keyboard shortcut. But if there is no manual at hand, they select the right option by trying different similar key combinations. Some laptop keyboards have a special button that turns the touchpad off or on; it may have a crossed out square on it. Unlocking the touchpad is easier.

But if the manual is not at hand, they select the desired option by searching through various similar key combinations. Some laptop keyboards have a special button that turns the touchpad off or on; it may have a crossed out square on it.

So, sometimes just turning on numlock mode can lead to problems with the laptop keyboard. If you do not have a user manual for your laptop, you should find one on the Internet at in electronic format. If you cannot solve problems with the keyboard or touchpad yourself, you will have to contact a service center, hotline telephone line or contact the manufacturer by email. Addresses of service centers, telephone numbers and email addresses of technical support are usually presented on the regional website of the laptop manufacturer.

The problem when the keyboard on a computer or laptop does not work is not uncommon. This situation is faced by both beginners and experienced users who have been working on a computer for many years. Let's figure out how to find a solution to the problem when the keyboard stops working, the 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.

There is information on the blog when the keyboard on a laptop stopped working: “”.

Beginner users usually immediately rush into panic and forget about the most trivial things. The very first thing you need to check is whether the keyboard is connected to the system unit (directly to motherboard).

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

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

Nowadays it is very popular to use demon wired keyboards and mice. If you have used wired keyboards before and this moment If you have a wireless one, then I remind you that batteries are discharged, and from time to time they need to be recharged.

All modern keyboards are connected through a special connector called a USB port. If there is a free USB port, then try connecting the keyboard to it. If all ports are busy, disconnect the printer or any other device to check the USB port for functionality 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 itself (motherboard). I once witnessed a situation where there was paper or chewing gum in the USB port, and therefore the keyboard stopped working.

It is possible that the keyboard has already done its job. To check if it works for you, you can go to your neighbors and ask them to connect your keyboard to their computer. If the keyboard works, then there is something wrong with your computer. You may have a spare keyboard, then connect it to your computer.

If the keyboard only partially prints, you may be unable to type numbers that are on the right side of the keyboard. If so, then press the "Num Lock" button.

What should I do if the keyboard does not work, but you have already done all the methods described above? If you have an old-style keyboard called PS/2 (piss in half), then pay attention to the legs. They may be curved or one of the legs may be completely absent. These legs may bend when connecting the device in a hurry, but they do not bend on their own. If there is no leg, 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 connector is the mouse.

If there are food crumbs 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 it gets hit, the rubber inside may slip off. When you disassemble the keyboard, you need to adjust and clean the rubber, if necessary.

Wipe the rubber 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 not to forget where all the keys were. In order not to get confused about the location of the keys, you can find a photo on the Internet that will be identical to your keyboard. Also, when disassembling, you can put the keys on the table in the order they were or take a photo with your cell phone.

If USB keyboard does not work, you can look in the BIOS to see if it is disabled. But there is one caveat: 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 a USB to PS/2 adapter. By connecting PS/2 you can now use the keyboard. Go into the BIOS and switch USB Keyboard Support to Enabled. We also make sure that the USB Controller is Enabled.

Another reason for the keyboard to fail is that the driver on the computer, which is responsible for the proper functioning of the keyboard, has stopped working. In such a situation, there are a number of steps you can take to try to troubleshoot the problem yourself.

Firstly, 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 ;).

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

If when you purchased your keyboard it came with a disk with drivers, you need to install them. Before installation, remove old drivers.

When the keyboard does not work: you now know what to do and how to find out the reason. Just in case, go through all the points; perhaps you missed some of them.

Keys do not work in a program or game

Users who like to play games sometimes encounter a problem when some of the keys do not work.

If the keyboard works, but after entering a program or some game, some keys refuse to work. In this case, it would be appropriate to first look at the assignment of the keys. If you are not satisfied with how they are set, then look for their settings in the game itself. In some games you need to save all changes, so don't forget about it.

Usually all hotkeys in programs are the same, but there are exceptions. To change them, find the key settings in the program itself. Change the part of the hotkeys that you are not happy with to the ones you are familiar with.

If your keyboard does not work, and you have tried everything that is described here, then you can buy the most regular keyboard, since their cost is not high.
