The arrow keys on the keyboard do not work. What to do if the transport card does not work "Arrow" The arrows on the keyboard do not work what to do

In the section on the question Why does the down arrow on the keyboard not work? When pressed, it doesn't work. All other keys are fine. given by the author freshly salted the best answer is If possible, try another keyboard to connect and check.
Then, in your keyboard - if possible - open it, take a look, the button may have moved out or it is crooked, as a result of which the opening / closing process does not work. And, of course, you can clean it up.
Well, a universal panacea is the purchase of a new keyboard, this business is now inexpensive.
Threat analogue of the "down" arrow - on the num panel (on the right side of the keyboard) - the num 2 button, with the num lock turned off; works the same for me.

There is no such key combination, besides, the computer was rebooted for sure? - so everything should have passed in this case. If you haven't reloaded, reload.
In general - here you need to show the user who will work - to another button to use it; there is no other way (well, the current purchase of a new Claudia remains).
In addition, you can be content with what you have, it's not catastrophic (why do you need "down" there? for scrolling? - so in many applications the slider with arrows on the right; for games? - in any game in the options you can reassign the control keys).

Good day.
Digging through various computer forums, you can often find users who have lost their mouse cursor. This happens for various reasons. To fix the situation, you must first deal with the source of the problem. In the article I will try to talk about all the possible options and how to solve them.

This option should not be taken into account, because if the mouse does not respond to movements, the cursor simply will not move. This will also happen as a result of the failure of the port to which the connection is made.

You can solve the problem by connecting an external device to a different connector. If this does not help, try a new device. In this way, possible problems can be ruled out immediately.

Virus( )

The first reason why the pointer disappeared is viruses. If some time before that you visited unverified sites, downloaded some files, and even more so installed something, the first thing to do is to check for malicious software using Comodo Internet Security or Dr Web Cureit. A clear sign is the situation when the mouse control disappears and it does something on its own.

The antivirus did not find anything - we go further.

Updates( )

A common cause on Windows 8 and 8.1 is the installation of system add-ons. The problem is related to the fact that new components damage some old files. As a result, certain elements of the operating system cease to perform their functions.

To solve the problem, you need to perform a number of actions:

If at the end of the check it is indicated that the files were restored, reboot and check the component's performance.

If some elements fail to “bring back to life”, run “ Upgrade Readiness Tool»:

As a result, everything should work.

Registry( )

Sometimes the problem manifests itself in Windows 10. At the same time, the previous tools do not help. To solve the problem, you need to make some changes to the system registry:

In many versions of Windows 10, this move helped.

Applications( )

If suddenly you observe a problem in games or after using some tools, this may be due to a conflict between individual elements. For example, such problems occur during the launch of Spin Tires and the game Port Royale 3. It is also not uncommon for these symptoms to be observed after a chat, but this is more likely due to browser problems.

Often the problem is solved by restarting the operating system. What to do if it didn't help? Most likely, reinstalling the application itself will help.

Imagine the situation, you turned on the computer, it booted up, but the keyboard does not work. And why the keyboard stopped working is not clear.

Agree, for many users, this will cause confusion, and some will even decide to give keyboard for repair

Well, if you have another old keyboard at hand, which you can check the overall health of the computer. But usually it is not, so let's try to figure out why the keyboard does not work and what to do to make it work again.

The advice in this article is universal. It doesn't matter what brand your device isa4tech, logitech, genius, oklick or any other - let's try to solve the problem.

6 reasons why the keyboard on the computer does not work

Here are a few simple steps that might help you fix your keyboard:

1. Keyboard connector disconnected from computer

Action one: we check our keyboard is connected to the system unit.

This reason is the most trivial - the contact in the connection between the computer system unit and the keyboard is broken. The keyboard connector is usually located on the back of the computer system unit. You can easily find it - in shape it resembles a domestic standard tape connector.

To fix this problem, you just need to securely fasten the keyboard cable connector to the mating connector on the computer system unit.

If necessary (for example, in case of unreliable contact), you can wipe the contacts on the keyboard connectors with alcohol.
Make sure the keyboard wire is not damaged.

Turn off the computer, disconnect and reconnect the keyboard.

You can check the performance of the keyboard itself on another computer.

2. The keyboard is connected to the wrong connector

Action insecond: we look not to the port for the mouse, whether we connected it by mistake, the ports for the PS-2 mouse and keyboard are nearby and differ only in color.

3. Checking the health of the PS / 2 port

Action trepeater: we look at the state of the PS-2 port for the keyboard itself, is it loose.

PS / 2 port performance can be checked with another keyboard

4. Checking the functionality of the PS / 2 connector

act four the most common, we look at the state of the keyboard plug itself, it is often stepped on, inserted incorrectly, deformed and broken. If you were not careful, you could bend the legs at the PS / 2 keyboard connector.

The arrow shows where the thin antennae-contacts of the plug are located, which are the easiest to bend and break.

Just note that the connector itself usually purple :o).

If the legs at the connector are bent, straighten them with something thin, such as tweezers or a knitting needle.

5. Keyboard with USB interface

In order for a USB keyboard to work on some computers, you need to enable the appropriate option in the BIOS, it is called USB Keyboard Support, opposite this parameter can be Disabled you need to set the value Enabled, it happens sometimes the settings in the BIOS fly off.

I understand that I do not want to go into the BIOS, but it is necessary. You need to go into the BIOS and check if the USB controller itself may be disabled and you will need to set it opposite USB Controller the Enabled value.

In this case, only the PS-2 keyboard can help, by connecting it, you can make your own changes to the BIOS and switch, for example, the option USB Keyboard Support, responsible for the operation of the USB keyboard from the position Disabled into position Enabled only after that, after saving your changes and rebooting, you will be able to work with the USB interface keyboard. Also pay attention to the parameter USB Controller is it enabled.

Save settings and exit BIOS

Then you need to reinstall the drivers for the keyboard. In the device manager, you need to remove the keyboard from the list of equipment and start searching for new hardware in the control panel

6. Drivers not installed

Now there is a huge number of new multimedia keyboards with additional keys that require certain drivers to work, which should come with this keyboard.

If, when buying a keyboard, drivers were attached to it, you need to find and install them, again after uninstalling the old drivers.

And, of course, if your wireless keyboard has failed, you need to check condition of batteries or accumulators.

All of these keyboard issues are typical. Now, let's consider special cases when the keyboard does not work.

the keyboard is locked with a key (lock) on the system unit;
the XT/AT switch on the back of the keyboard is set incorrectly;
There is a hardware problem with the keyboard.

The keyboard is locked with a key (lock) on the system unit

To eliminate the possibility of unauthorized access to the computer, a special lock is located on the front panel of the system unit.

With the key included with your computer, you can completely lock the keyboard. In this case, any keystrokes on the keyboard will be ignored by the keyboard controller, and when booting up, the computer will display a message stating that the keyboard is locked and you need to unlock it:

Keyboard is locked... Unlock it To connect the keyboard back, you must turn the key to the "open" position and restart the computer.

It should be noted that the use of a keypad lock by itself is not a sufficient means of protection against unauthorized access. For more information about how to share access to your computer, see How to protect the data stored on your computer.

Keyboard XT/AT switch set incorrectly

Most keyboards can be connected to both IBM PC/XT and IBM PC/AT computers. However, the keyboards of these computers operate in different modes. For compatibility, on the bottom panel of the keyboard is a switch to select the type of computer - XT / AT.

If you are connecting the keyboard to an IBM PC/XT computer, then this switch must be in the XT position, and if the keyboard is connected to an IBM PC/AT computer, then the switch must be in the AT position.

If the switch is in the wrong position, the keyboard may not work.

Sticky keyboard keys

The reason that keyboard buttons not working, is also sticky one of the keyboard keys. Sticking some keys can lead to unpredictable consequences. For example, if the Del key sticks on the keyboard, then after turning on the power, the SETUP program will start.

After prolonged use of the computer keyboard, it becomes dirty. As a result of this, individual keys on the keyboard can stick, that is, after pressing and releasing a key, the key contacts remain closed. Since the contacts remain closed, the keyboard controller enters the auto-repeat mode, as if you had not released the key.

The result of such sticky behavior can be the auto-generation of a sticky key character and a keyboard buffer overflow. For example, if the "q" key gets stuck and you are working with a text editor, then a very long string "qqqqqqqqqqqqqqqqqqq..." will appear on the screen, which, in addition, will grow at a catastrophic rate.

Look to see if one or more keys on your keyboard are being jammed.
Try pressing all the keys in a row.
After prolonged use of the computer, contamination occurs, in order to get rid of dirt, you must carefully disassemble the keyboard, clean it of debris and wipe the contacts with alcohol, only this is a very dreary business, remember that disassembling the keyboard is much easier than assembling it.
Try disconnecting the keyboard from the system unit for a short time and reconnect.

To protect the keyboard from dirt, you can use a special cover that covers the keyboard from above and protects the keyboard from dust. Typically, these keyboard covers are sold with the keyboard.

PS. It happens that the keyboard is blocked by a virus. An unlikely event, if there is such a suspicion, check the computer with an antivirus using a computer mouse

The keyboard could just fail. Do not be lazy, try connecting it to another computer, will it work: o).

According to remontcompa.ru, lib.csu.ru

Solution: Disable Scroll Lock.

Typically, if a cell is selected on a worksheet and you press the arrow keys, the selection will move between individual cells: up or down, or left or right, depending on which arrow key was pressed. However, if the arrow key is enabled when scrolling is enabled, scroll one line up or one line down. Or scroll one column to the right or left. Scrolling on the keyboard is a switch to the Lock key, as is the case with the CAPS LOCK keys. After pressing the SCROLL LOCK key is enabled. To move between cells using the arrow keys, SCROLL LOCK must be turned off.

Dust and debris

The first and most common reason why the arrows on the keyboard do not work is the presence of a large amount of dust and debris under the buttons. This is a fairly common occurrence, so you shouldn't be too surprised. Even if a person never eats anything at the computer, dust will still get inside the case and accumulate there.

As a rule, a large amount of dust inside the keyboard leads to the fact that the buttons become less sensitive to pressing or even stop responding to them.

What can be done in this situation? There are few options, or rather, only one - a complete cleaning of the periphery. You should not be afraid, because the keyboard is easy to clean.

First you need to take a picture of the keyboard itself on your phone or camera in order to remember the location of all the buttons. After that, you need to pull out all the buttons using a special tool or a small screwdriver. Once all the keys have been removed, you need to unscrew the screws on the back and disassemble the case.

Particular care and accuracy should be shown when disassembling and cleaning a special flexible film, on which all the tracks for the buttons are applied.

As for the washing and cleaning process itself, the buttons, membranes and housing can be cleaned in water with diluted shampoo. The film with tracks should be carefully wiped with a damp cloth if there are traces of dirt on it.

Once everything is washed, you need to wait for the parts to dry completely and then assemble the keyboard back.

Liquid

The second reason why the arrows on the keyboard do not work is spilled liquid on the keyboard. Fans of snacking near the computer often face a problem when a drink is accidentally spilled on the keyboard. And although most peripherals now have waterproof properties, nevertheless, such cases can adversely affect its operation.

For example, a person spills water on the keyboard, for some time the device continues to work, but soon they stop responding to button touches, and not necessarily all, it can be a certain group of keys. So, if the arrows on the keyboard suddenly stop working, you need to think carefully and remember if any liquid has spilled onto the device.

There is also only one way to solve this problem - a complete disassembly of the keyboard, cleaning and reassembly. It often happens that cleaning and washing is enough to get the device working again. If nothing helped, then you can try to take the keyboard for repair, but the cost of repair is not always justified, sometimes it's easier to buy a new one.

Sticky Keys

The next reason why the arrows on the keyboard do not work is sticky buttons. Many have heard of sticky keys, but there are two definitions for this condition. The first is when, when you repeatedly press a key on a computer monitor, a warning about sticky keys pops up. The second concept implies directly sticking of the keyboard buttons themselves, or rather their membranes.

The fact is that in each keyboard there are membranes, when pressed, one or another button is triggered. If, after pressing, the membrane does not return to its original position - this is called sticking. The main reason for sticking is that something prevents the membrane from returning. It can be anything: dust, dirt, spilled liquid, something sweet, wear on the membrane itself, etc.

What can be done in this situation? There are two options. If dirt has got under the membranes that do not respond to button presses, then it is necessary to clean them. If the membrane is worn out, then it must be replaced. An old non-working device may well come in handy here. If there is none at hand, then you can take the membrane, for example, from the button that you practically do not use.

Membrane displacement

Another reason why the arrows on the keyboard do not work is problems with the membrane. It has already been said above that the membrane can stick, but the problems with it are not limited to this. In addition to sticking, membranes can often move from their place, thereby ceasing to respond to touch. Especially often shifts occur on those keys that are constantly very actively used.

All that can be advised in this situation is to disassemble the keyboard and put the membrane back in place.

Arrow keys not working on laptop keyboard

Laptop owners also often face the problem when the arrows on their devices stop working or do not work at all. The fact is that on many laptops, some additional functions are assigned to the arrows, for example, turning off the screen or changing the volume, brightness, etc. To use additional functions, just press the buttons, but to use the arrows to which these functions, you need to press and then the arrow itself. This was done to prevent accidental keystrokes, but using the keys in this way is completely inconvenient.

The problem is also easy to treat. You need to go into the BIOS of the laptop and disable the corresponding option. Above is a video showing how it's done.
