Why is the button pressed badly on the mouse? Restoring the functionality of the left mouse button. Left mouse button not working - check power settings

During the day, an active computer user clicks the left mouse button tens of thousands of times, if he is busy with ordinary office work. The mechanisms in the manipulator are ready for this, and failure of the mouse due to a broken button is a rarity. In this case, situations are possible when pressing the left mouse button does not lead to the desired action. Sometimes a similar problem can only be observed with a double or triple click, which are supposed to be used in the Windows operating system. Below are some tips on what to do if the left mouse button is not working.

Computer mouse diagnostics

If the left mouse button does not work, the first step is to make sure that the problem is not related to mechanical or electronic damage to the manipulator. Even if the button “clicks” as before, the command may not work due to malfunctions in the mouse board components. To be convinced of this assumption or to refute it, you need to check the operation of the mouse on another computer.

Important: When connecting a USB mouse to a new computer, you will need to wait a while while Windows detects the pointing device and installs the necessary drivers for its operation.

If the mouse works on a third-party computer, you can continue testing it on the PC where there were problems, looking for ways to fix them.

Connecting the mouse to a different USB port

The most common USB mice on the market, and it is quite rare now to find manipulators with a PS2 connector. If your computer uses a USB mouse, first try connecting it to a different connector on the system unit. This is the most common reason for the mouse not working.

Remember that after plugging the mouse into a new USB port, you need to wait for a while until it is detected.

Disable power saving mode

The Windows 10 operating system has a power saving mode that automatically turns off some connected devices, considering that they are inactive. If the mouse is powered off or lowered, the left mouse button may not be pressed. You can verify that the problem is not related to the power settings as follows:

After making settings for all designated devices, restart your computer and check if the problems with the mouse persist. If nothing has changed and the left button continues not to issue commands properly, you need to check the power settings in the control panel. For this:

Having saved the changes made, restart the computer again and check the literacy of the manipulator.

If the problem occurs on the laptop, then you need to try to disable its touchpad, which may conflict with the mouse. The way to disable the touchpad differs on different laptop models. In most cases, to disable the touchpad, you need to press the FN function key on the keyboard and one of the F1 through F12 buttons, which displays the corresponding icon to disable the touch control of the mouse cursor.

Welcome all!

Not so long ago I watched a very amusing (even funny) picture: at work, one guy, when his mouse stopped working, stood and did not know what to do - did not even know how to turn off the PC ... Meanwhile, I tell you, many actions that users do with the mouse - can be done quickly and easily using the keyboard. I will even say more - the speed of work increases significantly!

By the way, I repaired the mouse for him pretty quickly - this is how the topic of this article was born. Here I want to give some tips on what you can try to do to restore mouse operation ...

By the way, I will assume that your mouse does not work at all - i.e. the pointer doesn't even move. Thus, I will give in each step the buttons that need to be pressed on the keyboard in order to perform this or that action.

Problem number 1 - the mouse pointer does not move at all

This is probably the worst that could have happened. Since some users simply did not prepare for this at all. Many do not even know how to enter the control panel in this case, or start a movie, music. Let's look at it in order.

1. Checking wires and connectors

The first thing I recommend doing is checking the wires and connectors. Wires are often bitten by pets (cats, for example, love to do this), accidentally bend, etc. Many mice, when you connect them to a computer, start to glow (inside the LED is on). Pay attention to this.

Also check the USB port. After fixing the wires, try restarting your computer. By the way, some PCs also have ports on the front side of the system unit and on the back - try connecting the mouse to other USB ports.

In general, basic truths that many neglect ...

2. Battery check

This applies to wireless mice. Try to either change the battery or charge it, then check again.

3. Troubleshoot mouse problems through a wizard built into Windows

In Windows there is a special wizard, which is just designed to find and automatically eliminate various problems with the mouse. If the mouse LED is on, after connecting it to the PC, and it still does not work, then you need to try using this tool in Windows (before buying a new mouse).

1) First, open the execute line: press the buttons simultaneously Win + R(or the button Winif you have Windows 7).

2) In the execute line, write the command Control and press Enter.

3) Then press the button several times TAB(on the left of the keyboard, next to Caps lock). You can help yourself arrows... The task here is simple: you need to highlight the section " Hardware and Sound". The screenshot below shows what the selected section looks like. After selecting - just press the key Enter (this will open this section).

Control panel - hardware and sound.

5) Next, using the buttons TAB and arrow highlight the mouse and then press the key combination Shift + F10... Then you should have a properties window with a cherished tab " Troubleshooting"(see screenshot below) Actually, open it!

To open the same menu: select the mouse (TAB key), then press Shift + F10.

By the way, after checking, there may not be any instructions for you, and your problem will be eliminated. Therefore, at the end of the check, click the finish button and restart the PC. Maybe after reboot everything will work ...

4. Checking and updating the driver

It happens that Windows incorrectly detects the mouse and installs the "wrong driver" (Or there was just a driver conflict. By the way, before the mouse stopped working, you did not install any hardware? Perhaps you already know the answer ?!).

To determine if everything is in order with the driver, you need to open device Manager.

1) Press the buttons Win + R, then enter the command devmgmt.msc (screenshot below) and press Enter.

2) Should open "device Manager"... Notice if there are any yellow exclamation marks in front of any kind of equipment (especially in front of the mouse).

3) To update the driver: simply with arrows and TAB buttons highlight your device, then press the buttons Shift + F10 - and select "update drivers" (screen below).

4) Next, select automatic update and wait for Windows to check and install the drivers. By the way, if the update does not help, try removing the device (and the driver along with it), and then reinstalling it.

5. Checking the mouse on another PC, laptop

The last thing I recommend in case of a similar problem is to test the mouse on another PC, laptop. If it does not work there too, there is a high probability that it has come to an end. No, you can try to get into it with a soldering iron, but what is called " game - not worth the candle".

Problem number 2 - the mouse pointer freezes, moves quickly or slowly, in jerks

It happens that for a while the mouse pointer seems to freeze, and then continues to move (sometimes it just moves in jerks). This can happen for several reasons:

• too strong CPU load: in this case, as a rule, the computer slows down in general, many applications do not open, etc.;
• system interrupts "work", disrupting the stability of the PC (see also the link above);
• problems with the hard disk, CD / DVD disk - the computer cannot read the data in any way (I think many have noticed this, especially when you take out a problematic medium - and the PC seems to hang down) .;
• some types of mice "require" special settings: for example, the Logitech MX Master gaming computer mouse - may become unstable if the checkbox with increased pointer precision is not cleared. In addition, you may need to install the utilities included on the disk bundled with the mouse (it is better to install them all if problems are observed)... I also recommend going to the mouse settings and checking all the checkboxes.

How do I check my mouse settings?

• pointer movement speed: try changing it, too fast movement of the mouse often affects its accuracy;
• increased accuracy of the pointer setting: check or uncheck the box next to this item and check the mouse. Sometimes, this tick is a stumbling block;
• show mouse pointer trace: if you enable this checkbox, you will observe how a trace of the mouse movement remains on the screen. On the one hand, some users will even find it convenient (for example, the pointer can be found faster, or, if you are filming a video for someone from the screen, show how the pointer moves), on the other hand, many consider this setting to be a mouse "brake". In general, try turning it on / off.

Properties: Mouse

Just one more tip. Sometimes the mouse connected to the USB port freezes. If you have a PS / 2 on your computer, then try using a small adapter and connect the USB to it.

Problem number 3 - double (triple) click works (or 1 button does not work)

This problem most often appears with an old mouse that has already worked pretty well. And most often, I must say, it happens with the left mouse button - since all the main load falls on it (even in games, even when working in Windows).

By the way, I already had a blog post on this topic, in which I advised how easy it is to get rid of this ailment. It was about a simple way: swap the left and right buttons on the mouse. This is done quickly, especially if you have ever held a soldering iron in your hands before.

Replacing the right mouse button with the left mouse button.

If you didn't, there are two options: ask a neighbor or friend who is about to do this; or go to the store for a new one ...

By the way, just as an option, you can disassemble the mouse button, then take out the copper plate, clean it and bend it. You can read more about this here (although the article is in English, but the pictures are clear): http://www.overclockers.com/mouse-clicking-troubles-diy-repair/

PS

By the way, if your mouse periodically turns on and off (which, by the way, is also not uncommon) - 99% of the problem is in the wire, which periodically leaves and the connection is lost. Try to fix it with tape (for example) - this way the mouse will serve you for more than one year.

You can also climb in with a soldering iron, having previously cut off 5-10 cm of wires in the "right" place (where the bend happened), but I will not advise this, since for many users this procedure is more complicated than going to the store for a new mouse. ..

Advice on a new mouse. Eif you are a fan of newfangled shooters, strategies, action games - you would like some modern gaming mouse... Extra buttons on the mouse body will help increase micro-control in the game and more efficiently issue commands and control your characters. In addition, if one button "flies", you can always shift the function of one button to another (ie, reassign the button (I wrote about this above in the article)).

Good afternoon!

In general, I want to note right away that the left mouse button is one of the most loaded. It would seem, well, what is a simple office job? But with it, LMB * per hour (on average) is pressed up to 100 or more times! In some games, the indicator can be several times higher (in general, the load on it, God forbid ...).

And if it refuses, work on a PC becomes very inconvenient (and in some cases even impossible). In general, it would be more correct to divide the problems into hardware and software (for example, if the button itself is broken, then this is a hardware problem, if the problem is in the driver, for example, it is software). Actually, based on this, I will try to share this article ...

And so, let's get down to business.

* Popular abbreviation: "LMB" - left mouse button.

Is the mouse problem? (We diagnose!)

The very first thing I recommend in this case is to check if everything is in order with the mouse itself. Often, with heavy use, the mouse button itself stops working (and you need to press it too hard for it to respond). By the way, a characteristic symptom in this case: periodically the mouse LMB does not react, then it starts to work, moreover, often a double click is obtained at once.

For diagnostics: just connect the mouse to another computer / laptop (which does not have a similar problem). If it behaves similarly on it (i.e. LMB does not work), then the problem is probably in the mouse (the button may be out of order, the board is damaged, etc.).

In this case, there are two ways: either buy a new mouse, or try to repair it (if you have free time to experiment).

By the way!

You can buy cheap mice (and other computer hardware) in Chinese online stores. I recommend taking a quick look at this post:

A few words about its repair

If you have experience in soldering, you can try to disassemble the mouse, clean it from dust and see if any contacts have gone where, if everything is in order with the board. If everything is OK, then you can try to solder a new one instead of the old button. In principle, there is nothing complicated here (unless you may need old mice from which to take a working button).

By the way, you can also try to set the right button in place of the left one, and the left button to the right. This option is especially relevant in cases when your LMB does not work well (or there is a double click).

Services, as far as I know, do not repair mice (since the wizard's time is more expensive than a new mouse). Unless you have an expensive gaming mouse (with which you have already become akin, and are ready to pay any reasonable amount for it) ...

What to do if the mouse itself is functional, but LMB does not work

This is a more interesting option (ie on another PC the mouse works and everything is in order with it, but on the current one it behaves "strange" for some reason). In general, one of the first tips would be to try restarting your computer (sometimes a similar problem occurs due to various system failures, high CPU load, etc.). If the reboot does not work, then I recommend the following ...

1) Try connecting the mouse to a different USB port

It is highly advisable not to connect it to the USB ports that are on the keyboard, go through some kind of splitters, etc. adapters. Connect to the USB on the back of the system unit (if you have a laptop, then directly to it). In any case, check several of your USB ports in sequence.

If you have a problem with a PS / 2 mouse, connect it to the USB port via the adapter.

2) Check the power saving mode

The fact is that when it is running, the computer can turn off the mouse in order to save energy. To check if this is so, you need to open the device manager (I will give a way to do this without a mouse):

1. press Win + R to bring up the Run window;
2. enter the command devmgmt.msc;
3. press Enter.

AT device manager find the tab "Mice and other pointing devices" (see screenshot below). If the mouse does not work for you: first press "TAB" (to make the pointer appear) and then to move up and down use the buttons " "," ↓ "(note: usual" arrows "on the keyboard), press to expand the tab "→" .

Selecting the desired device (for example, "HID Compliant Mouse". By the way, you may have a slightly different name) just press "Enter".

Next (using the "TAB" and "arrows") open the "Power Management" tab and uncheck the "Allow this device to turn off to save energy" checkbox. Save your settings and restart your computer.

3) Check the power supply parameters

5) Check the drivers for the mouse (this is especially true for gaming mice that come with additional buttons)

According to statistics, as a rule, more problems arise with fancy mice: which have additional keys (they are often used in games for quick access to the game character). So, for such mice, it is often necessary to install drivers manually (because the driver that picks up Windows may not work correctly with it).

In general, the topic of drivers is "quite" extensive. If you do not know how to update them, I recommend using the materials, links to which are below:

1. 10 Best Driver Updaters (Automatic!) -
2. How to find and install a driver for an unknown device -

Additions on the topic are welcome ...

It began with the fact that the left button perceived pressing only with a significant effort, and when pressed without effort it did not work every time. If the mouse button no longer works, and everything started the same way, then the repair plan is the same. The mouse wheel is also not eternal, its restoration is described in the article, and if the wheel is alive, but does not work well (in jerks), then about it here:. It was decided to get to the insides of a non-working mouse button and clean the contact points. It would be nice to disassemble the mouse to get to the button. There were no difficulties with this: I unscrewed two screws in the battery compartment and the case opened:

The photo below shows the culprit. A small button in the center of the photo next to the inverted SW1 caption:

Now you need to disassemble the button itself

Its upper part sits on four plastic pins soldered on top. We carefully cut this fastener with a clerical knife, pick it up and remove the upper part with it. We now have access to the internal parts: the moving parts of the button and the contact metal membrane (see photo below).

The underside of the membrane, which is the closing one, is covered with a dark coating, and we need to remove it. Rubbed with alcohol, then rubbed well - did not help. Then I had to use a mechanical method - cleaning with a clerical knife, but only very carefully without unnecessary efforts, so as not to damage the membrane, because it may lose its ability to click.

It will not be superfluous to clean the rest of the buttons, for sure they are also covered with a coating and will soon begin to work poorly. Tested on personal experience, and it was. Here are a couple of photos showing the result of cleaning:

The mouse is the main element for controlling the cursor and giving various commands to a computer or laptop.

Any interruptions in the operation of this device seriously reduce performance even in the simplest text programs, not to mention work in graphic editors, where most of the operations are performed using the mouse.

There can be several reasons for the malfunction of the left mouse button, and all of them can be divided into three groups:

• Mechanical damage, dust and dirt under the button, physical wear and tear of individual mouse elements;
• Technical - damage to the wire, poor contact in the connector, inoperative USB port, etc.;
• Software - damaged drivers or failures in the operating system settings.

Elimination of technical problems

If the left mouse button does not work or works every other time, first you need to make sure that the problem is not technical in nature.

For this:

1. Try connecting the mouse to a different USB port, the system should "see" it in a few seconds;
2. Check the condition of the wire. It only looks thick and strong enough, in fact, inside there are several thinnest conductors as thick as hair. In the process of intensive use, the integrity of the wire may be compromised. Check the wire carefully for kinks or pinched areas. If there is a cat or other pet at home, it is possible that he tried the wire to the tooth;
3. If possible, connect the problem mouse to another computer / laptop.
4. If the mouse works correctly on another device, then you should look for a solution to the problem in the PC settings.

Eliminating software inconsistencies

If the mouse works fine on another device, you can solve the problem in a couple of minutes by going to the computer settings.

For this:

1. Check the settings in Device Manager. If the left mouse button does not work in Windows 10, then it is quite possible that the reason for the failure is the enabled power saving mode. This mode can also apply to the controller of USB ports.
2. To check this version, in Device Manager, open the tab "USB Controllers", then go to "Generic USB Hub" and USB Root Hub.
3. Open each of them sequentially and go to the section "Power Management", where uncheck the box next to "Allow this device to be turned off to save energy"... Perform the same steps for each USB controller.

Check the power settings in the Control Panel.

1. To find this tab, hammer in the search bar (search in Windows) the phrase Power settings.
2. A list of plans will open in the window that appears, one of which will be marked as the main one (used by the system at the moment). Go to the settings of the main plan (button "Change plan parameters") And select the item" Change advanced power settings«.
3. In the settings, select the sub-item " Option to temporarily disable USB port"And deselect this option by selecting the" Forbidden "option.

Check the touchpad settings on your laptop.

In the 10th version of Windows, the operating system can block the operation of the computer mouse if the user works with the keyboard for a long time. To fix the problem, you should look into the touchpad settings and discard the delay function.

Mechanical damage

Next, you should check the mouse for mechanical damage. You should go to this point last, since the device will have to be completely disassembled for diagnostics.

As a rule, interruptions in the operation of buttons due to contamination or wear of the microswitch occur gradually: at first the button works every other time, then a stronger press is required, and then the computer completely stops responding to mouse commands.

If the reason is a dirty microswitch, then to fix the problem it is enough to disassemble the mouse and clean all the controls.

If the microswitch is worn out, it will need to be replaced. In the case of a cheap mouse for 250-500 rubles, this does not always make sense - it is easier to buy a new one with a guarantee. It is quite another matter when it comes to an expensive gaming device worth several thousand - in this case, your favorite mouse can be repaired.

To do this, it is enough to buy a new microswitch, the cost of which does not exceed 100-200 rubles (it is advisable to immediately purchase a part with an increased resource).

Do-it-yourself repair of poorly working buttons on the mouse

The main reason why the mouse buttons stop working is the wear (breakdown) of the microswitch. To repair a computer mouse, in this case, it is enough to simply replace the problematic element.

This will require the following parts and tools:

• New microswitch (it is highly desirable to purchase a "native" part);
• Slim flat screwdriver;
• Small Phillips screwdriver
• Tweezers;
• Soldering iron + solder;
• Side cutters.

The procedure is as follows:

1. We disassemble the mouse case. The main screws are in most cases hidden behind glides (sliding "legs"), so these pads need to be removed. This is easy to do with a thin flat screwdriver - you just need to carefully pick up the cover at the base. After repair, the glides will return to their place, so they should be put aside for a while. When all the screws are removed, the top cover can be removed.
2. We remove the fee. To do this, unscrew a few screws (usually 5-7), remove the scroll wheel and disconnect the 2 contacts with tweezers.
3. We solder the old microswitch. We recommend using a small flat screwdriver for this. We insert it between the main board and the microswitch, and we begin to warm up the contacts, gradually pushing the screwdriver under the switch.
4. We clean the mounting holes from the old solder. It is convenient to do this with an awl or a thick needle.
5. We solder a new microswitch - just insert it into the holes and lightly grip it with a soldering iron. The protruding "antennae" of the microswitch contacts are carefully cut off with side cutters.
6. We clean the upper part of the mouse case from dirt and dust.
7. We collect the mouse, glue the "legs" in place.

That's all, the mouse is completely ready to go!
