If the mouse works, the button is not pressed. Left mouse button not working or malfunctioning: how to fix it? Operating system problems

During the operation of complex technical means like a computer, many questions often arise about the operation of additional equipment and tools. There can be a lot of problems when using a mouse and keyboard, eternal computer satellites. Especially from frequent use, the right mouse buttons may stop working. What to do if this happens, you can read below.

Breakdown reasons

Rough handling and careless use of devices can adversely affect their performance. It is highly discouraged to use strong physical impact on the equipment: hitting the mouse or throwing it against the wall will not lead to anything good. But what to do - the right mouse button does not work and some of the functions are no longer available? First you need to determine the cause of the breakdown.

The fact is that, in addition to physical reasons, the mouse may not function also due to problems in the operating system itself. On the Internet, you cannot visit suspicious sites, download anything from unverified sources, and you also cannot take someone else's memory cards and insert them into your computer without first checking the media for viruses.

Recently, wireless usb mice have become more common. They run on batteries, so before looking for a problem in the computer or carrying the mouse for repair in service center it is worth trying to simply change the battery and check that it is turned on. Typically, the "on-off" switch is located on the back, which is usually driven across the table.

But what to do: does not work, despite all the efforts? Then experienced electronics and technology masters can give a hint, especially if it is difficult to figure it out on your own.

Operating system problems

If replacing the battery with a new one or changing the switch mode did not help, then you need to try to check the system operation in the computer. This will allow you to understand what to do with the right mouse button, it does not work itself or a software problem.

For this, a configuration example will be given on the Windows 10 operating system, since this latest version proposed by Microsoft, which means that it is the most problematic when it comes to identifying hardware.

First you need to click the Start Menu button. And go to the system settings by clicking on the "Options" icon to the left of the list of applications.

In the menu that opens, select "Devices".

And in the list that opens, find "Mouse". In the submenu, you can select the main button: left or right. They need to be swapped and again tried to use the equipment. If now the left one does not work, the right mouse button (you should not do something yourself with this, you should call the computer wizard) is functioning, which means that the problem is in a virus on the computer.

After checking, do not forget about returning the parameters to the original data.

Contacting the service center

If it is not possible to identify the cause of the breakdown, or it is clearly after exposure of a physical nature, then you need to contact the manufacturer's service center or the department for repairing computers and household appliances.

Craftsmen will be able to determine the cause of the breakdown and suggest repair options. In some cases, repairing a computer mouse can cost more than buying a new one, so it is recommended that the proposed alternatives be carefully weighed and considered.

Suddenly having problems with your mouse on Windows? The left button sometimes does not work and you need to click 3-4 times to launch a program or a shortcut on the desktop? Why such a problem occurs and what to do to fix it.

One of the more annoying mouse issues is the issue with its left button. A situation arises when suddenly, for no apparent reason, the left mouse button does not work, or it starts to respond to the user's clicks every other time.

Every fourth or fifth click is not perceived by the system, this behavior is very annoying, because it makes it difficult to work on the computer - instead of double-clicking on the program's shortcut, sometimes you need to click 3 or 4 times. This also applies to performing any actions - we want to quickly select, for example, a group of shortcuts on the desktop to drag them with the mouse cursor, but it turns out that the left button does not work. Why doesn't the left button always respond to user clicks?

Of course, the problem may be in the mouse itself and the damage is purely technical. The left button is worn out and doesn't always respond to clicks. In this case, you need to repair it or buy a new mouse.

But before you do this, you need to check if it works on another computer, or - if possible - connect another working mouse to the computer. Thus, you will be able to exclude or confirm its technical malfunction. But if, you connect the problematic mouse to your friend's computer and it works correctly, then this means that there is a problem with your PC. Then there is no point in buying a new mouse - you should look for a solution in the Windows 10 settings.

Step 1: Connect the mouse to a different USB port

See which input your mouse is connected to your computer. In most cases, the connection is made via a USB port, but devices with a PS2 connector are still rare.

The first step is to check the serviceability USB port, because it can be damaged and cause problems with operation. Connect the mouse to a different port without turning off the power of the computer - it should be detected in a few seconds.

Step 2: Check the settings in Windows Device Manager

If the above method does not work, the culprit may be the controller responsible for the operation of the USB ports. The system is equipped with a function that, as part of the energy-saving mode, turns off or reduces the activity of individual components of the computer. There is a possibility that the mode is affecting the USB driver and therefore Windows 10 sometimes "does not pick up" the left button clicks.

In Windows 10, right-click on the Start button and go to Device Manager or call it with the command “devmgmt. msc "

Expand USB Controllers. Here you will find items such as Generic USB Hub and USB Root Hub. Double-click each one and go to the Power Management section.

Uncheck the "Allow this device to be turned off to save power" checkbox. Repeat these steps for each item under USB Controllers.

Step 3: Check Power Options

The next step is to configure the power settings for the active profile. To do this, go to the Windows 10 Control Panel and enter "Power Settings" in the search box in the upper right corner.

A window with a list of basic and sub plans will appear. One of them will be marked, that is, the one used by the system. Click next to it on the item "Change plan settings", and then in the new window select "Change advanced power settings".

Find “USB Options - Disable USB Port Temporarily Option” and select “Disabled”. Then check how the device works.

Step 4: turn off touchpad lag (in laptops)

Windows 8.1 and 10 are packed with features that are useful for laptop users, including slower response to clicks while typing. Have you ever happened to be typing on a laptop and accidentally touched the touchpad with your palm, causing the mouse cursor to jump?

The touchpad lag serves to prevent such situations. When the laptop detects that you are using the keyboard, click delay is triggered. However, this feature may not be convenient for players who play on laptops with mice, and here's why.

It turns out that in some cases the function blocks the action of the mouse buttons connected via USB. If you are playing on a laptop, then your hands are usually on the keyboard all the time - the rest of the input devices, for system reasons, should not be involved.

The delay function treats the game in the same way as typing, and blocks mouse clicks for a short period of time, and, unfortunately, periodically (the button fires every other time). In this case, the latency feature on the laptop can be disabled.

Users sometimes face such a problem when the mouse stops responding to clicks. What is the reason for this problem? How can you deal with such a task? What features of this process are recommended to pay attention to? In some cases, factors that have absolutely nothing to do with input devices can influence the mouse. The user can immediately carry the faulty item for diagnosis to system administrators. This is a completely logical decision, but there is still no need to rush. You can try to figure out on your own why the mouse does not respond to clicks, and try to cope with the problems without assistance.

Mouse does not respond to clicks: clogging

The first and most common reason for the lack of response to clicks is a banal clogging of equipment. If the mouse refuses to respond to a click or does it every other time, then it is recommended to check it for cleanliness. It is possible to eliminate such a problem as clogging only on completely new equipment. If the device has already worked for some time, then in case of problems with the mouse, you can start cleaning this component. This is not so difficult to do, and the result will not be long in coming. When the user gets rid of all the dirt that has accumulated under the mouse buttons, it will work in full force.

Mouse does not respond to clicks: malfunction

We have considered only one scenario. In fact, there are many options. What if the mouse doesn't respond to clicks? The equipment is likely to be out of order. This is true for any devices, both new and already working for some time. If the equipment is defective, it is recommended that you take it to a service center. Here the craftsmen can check the device and say if it needs to be repaired. If yes, then you can safely leave the mouse until troubleshooting at the service center. Otherwise, you will have to completely change the input device.

Functional check

Even if the mouse, even if it is cleaned of dust and dirt, still does not respond to responses, it will still be possible to test its performance. To do this, it is recommended to connect the device to another computer, install drivers for the equipment and make sure that everything is working properly. This technique makes it possible to make visits to service centers with specific claims. This test can help you identify the sources of failures and problems.

What other options are there for the development of events? What should you pay attention to in other situations?

Connectors and jacks

What if the mouse refuses to respond to clicks? First of all, don't panic. This problem is common for many users. Sometimes the problem is technical. However, it does not pose any danger to the operating system or computer. Possible cause the problem may become a damaged connector. If the socket to which the equipment is connected is damaged, then the contact between the mouse and the pointing device can be established every other time. There is only one way out of this situation - try to connect the mouse to another socket. This is the only way to fix the problem. It is worth noting that the connector on the device may also be damaged. The best way to remedy the situation in this case is to buy a new mouse. Generally, connectors cannot be repaired. After the repair work, they still break down, and quite quickly.

Drivers

What if the mouse stops responding to mouse clicks or does it every other time? There can be many options for the development of events. As mentioned earlier, problems are often technical in nature. However, there are exceptions. The layout, which will be discussed below, is typical for gaming mice. The problem usually lies with the drivers. This software responsible for recognizing devices in the operating system. Complete absence of this software or old version can lead to the fact that the mice will work every other time or will not be detected by the computer at all as available equipment. In this case, you only need to install the drivers on your computer (usually they are already attached to the mice). You can also try updating your existing drivers. After that, the operating system should be rebooted. If these procedures have brought a positive result, then there is no need to worry. If the mouse refuses to work, then you need to continue to look for the source of the problem. There are many alternatives.

Touchpad

Only laptop owners can face this problem. Is there a cursor on the screen, but the mouse does not always respond to clicks or refuses to work at all? You can try to test the touchpad operation. If it functions normally, it is recommended to disable this component. The whole problem lies in the fact that some assemblies of the operating system and laptops do not support the simultaneous operation of the mouse and touchpad. The result is a hardware conflict. The mouse refuses to function properly. When the touchpad is disconnected, the connected device will be fully functional again. You can continue to use the mouse. And don't be surprised if the problem appears suddenly. Nobody is safe from such situations.

CPU

If the mouse does not respond to clicks, then the problem may lie elsewhere. Slow response from input / output devices in some cases can be explained by high processor load. Why can such a phenomenon be observed on a PC? There are many options for the development of events. The most common are the following:

- a large number of functioning programs;

- non-compliance of the PC with the system requirements of the operating system;

- exposure to viruses and other malicious objects;

- long operation of the equipment without rebooting or shutting down;

- Insufficient hard disk space for the normal operation of the operating system.

In any case, it is necessary to provide unloading to the processor. In this case, the user is advised to close numerous programs that are running in the background. You can also restart your computer. Better to let him rest for a couple of hours. After that, the user must renew the attempt to connect the keypad. The problem should go away.

Impact of viruses

What if the mouse doesn't respond to clicks? As mentioned above, the real cause of hardware problems may well be virus activity. A computer infection may well lead to this phenomenon. What to do in this case? It is necessary to try to cure the computer. If this problem occurs while working on a laptop, then the touchpad will save you. With the touchpad, you can easily control the cursor and the PC. Antivirus program will be able to find and disinfect potentially dangerous files. If this fails, the user will be prompted to delete the document. When the cursor cannot be controlled at all, the computer is usually taken to a service center. There they will quickly be able to cure your system of all viruses, without causing any damage to the owner's data.

Incompatibility

If the mouse refuses to respond to clicks, then it is recommended to pay attention to the system requirements. The problem may be that all modern equipment has certain system requirements for the computer. Failure to meet the system requirements may make the device impossible to operate. Or it will be unstable. If an incompatibility with the operating system is found, the problem can be solved in several ways. The user can either change the operating system or change the connected equipment. In practice, the second option is most often encountered. It is recommended to pay special attention to compatibility issues for owners of devices running on the operating system Windows 10. A lot of equipment today conflicts with this operating system. Therefore, do not be surprised that the operating room Windows system does not respond to mouse clicks. How to be in this situation? It was already said earlier that it is necessary either to change the operating system, or to change the connected equipment. How exactly to proceed in this case? Everyone decides for himself.

Power supply

The last reason a mouse connected to a computer may not respond is wrong settings power supply. This problem usually occurs on laptops. It is recommended to go to the power settings and disable the function that allows the disconnection of USB ports. It is to them that information input-output devices are directly connected. Then you need to save all settings and restart your computer. After that, the work of the mouse, as practice shows, is getting better. It's actually not all that difficult. You just have to go through all the available options. Then you will be 100% able to figure out why the problem occurred. Don't rush to buy new equipment. It is likely that it will be possible to do without it. If the user doubts his abilities, then you can immediately carry the computer and faulty equipment to the service center. They will quickly help you diagnose the malfunction and fix the problem that has arisen.

Despite the fact that most computer manipulators or mice are a universal type of device, sometimes quite serious problems can be observed with them. One of the most common situations is when the left mouse button does not work or does not work as expected (every other time, calls the context menu, etc.). Why this is happening, and how to fix the situation, then we will consider in as much detail as possible.

Left mouse button not working: what is the reason?

Speaking about what can cause this phenomenon, first of all, it should be noted that there are problems with the device itself. Indeed, various kinds of mechanical damage can provoke situations when the left mouse button works every other time. However, oddly enough, this may not always be the root cause.

Quite often, the problem can be with the device drivers. True, for the most part this applies to game manipulators, for which you need to install a fairly specific control software. But this can happen with standard devices too.

No less common are problems of incorrect connection or even situations where blocking of mouse operation is performed at the software level. For most of these cases, you can find a more or less suitable solution for restoring the device to work. Let's try to consider some of them. We are not talking about viruses, since such cases can be met very rarely, although their impact is not excluded.

Changing the pointing device connection

So, we assume that the left mouse button does not work. What can I do to fix the problem?

To get started, try simply restarting your computer or reconnecting the mouse, if it is a USB or wireless type, to a different port. For devices of the PS2 standard, re-enabling should be done only when the power is off, and for USB modifications of the manipulators, this can be done, as they say, right on the go. But this is only the simplest thing that can be, and usually the problem is hidden much deeper.

Configuring Power Saving and Power Scheme

Let's see what can be done if the left mouse button does not work or works in the wrong mode (for example, for a double click, you need to make more than two clicks, or there is no reaction to pressing the button at all).

The proposed solution applies only to USB devices and is not applicable for conventional type of manipulators:

1. To begin with, in order not to take any action with the drivers, you need to call the "Device Manager" (devmgmt.msc in the "Run" menu).
2. Find all Generic USB Hubs and USB Root Hubs there (there may be more than one).
3. For each, view the properties section with a switch to the power management tab.
4. If there is a check mark in front of the device shutdown point to save energy, it must be unchecked, then save the installed options and restart the system to be sure.

Sometimes it also happens that the left mouse button does not work due to incorrectly set parameters in the current power supply scheme, which is more typical for laptops.

In this situation, it is necessary:

• go to the appropriate settings using the "Control Panel" or the RMB menu on the battery icon;
• reveal additional parameters;
• set a prohibition in the options for temporarily disabling USB ports.

Disable touchpad latency on laptop

On laptops, this problem is very often associated with the fact that the operation of the mouse button (not necessarily the left one) is influenced by the included touchpad. It should be disabled, either by using the keyboard shortcuts based on the Fn button, or directly in the manipulator parameters settings, which are located in the corresponding section "Control Panels".

A similar procedure can be performed in the "Device Manager" by selecting the disable for the touchpad.

What if the left mouse button works like the right one?

If the problem is that the left button for some reason invokes context menus, and does not work on selection or input operations, then, most likely, the mouse settings related to changing buttons have somehow been changed.

To fix the problem, use the "Control Panel" and the section of the mouse settings. Here you need to uncheck the box from the button assignment exchange point, if it is checked there.

What else could there be?

Just in case, see if you have any additional mouse control software or button remapping software installed. It can also cause such situations to arise.

Finally, if all else fails, in Device Manager, simply remove the mouse from the list and then reboot your system. It may very well be that Windows will install required drivers again, and the problem will disappear by itself.

But, if after that nothing changes, check the manipulator for operability on another PC, and if necessary, hand it over for repair or buy a new one. Fortunately, now such devices are inexpensive.

If your mouse does not work well, then take your time
run to the store for a new one, and try to "cure" the old one.

Initially - make sure
that there is no problem in the mouse itself.

If wired - is the wire damaged?
If it's wireless - is it time for the battery?
change or fix the USB-connector.

If everything is in order with this, then connect Windows to the problem.

There are tons of ways to improve your mouse experience on your computer.
Can customize mouse operation"For yourself" or change the pointers.

And you can troubleshoot
or update the configuration.

In different Windows packages, the path to the mouse settings may differ.
In Windows 7 - as described below. In other Windows packages - maybe
be different. But the mouse settings are a must.

The beginning of the path to elimination
problems starts with the Start button.

In the right column of the menu, the Start button, if any,
select "Devices and Printers".

A window will open in which there will be all devices,
connected to your computer.

If there is no function in the right column of the Start menu
"Devices and Printers", then click "Control Panel".

And select in the "Equipment and Sound" section -
button "View devices and printers".

Or you can click "Hardware and Sound"
and in the new Devices and Printers window.

In any of the options - a window will open
with connected devices (screenshot above).

For troubleshooting - click
over the mouse file to highlight.

If there is no File button in Explorer, right-click
by clicking on the mouse file. A context menu will open.

And choose, from the context menu, "Troubleshooting".
Wait for the troubleshooter to diagnose the problem (this may take a few minutes), then follow the instructions.

Although there may not be instructions.
If the problem is solved without your participation.
An active "Finish" button will appear at the bottom of the window.
Press and, for correct operation of the mouse,
restart your computer.
Everything!

How to update mouse configuration

If the troubleshooter doesn't help
a problem with the mouse - the configuration can be updated.

This can be done through the device manager.
You can find it through the Start button.

Start → Control Panel → Hardware and Sound.

Under Devices and Printers, click Device Manager. Such a tab will open.

In this tab, find the mouse, right-click
mouse and select "Update hardware configuration".
And the program will update.

And another problem happens with the mouse - the computer does not respond.
on clicks of the left mouse. I myself, recently, faced such a phenomenon.
The mouse pointer moves across the screen, the left mouse clicks, but does not open anything. No windows, no start - nothing. The right mouse opens the context menu, while the left mouse cannot open anything from this menu. Neither an emergency shutdown of the computer, nor all kinds of advice from the Internet (about the Enter key and the "hot keys" Ctrl + Alt + Del) - did not help to solve the problem. At first I thought that there was a problem with the computer, and then I connected another mouse. And after Windows installed the driver for this mouse, everything worked fine.
