How to make the mouse work. The cursor does not respond when pressed. Mouse does not work: what to do. Features of the mouse connector

Mouse or pointing device - a device for controlling the cursor and transmitting some commands to the operating system. On laptops, there is an analogue - a touchpad, but many users, for various reasons, prefer to use a mouse. In this case, situations may arise with the impossibility of using the manipulator due to its banal inoperability. In this article, we'll talk about why the mouse on a laptop may not work and how to deal with it.

In fact, there are not many reasons for the inoperability of the mouse. Let's analyze the main ones, the most common ones.

• Sensor contamination.
• Broken connection port.
• The cord is damaged or the device itself is faulty.
• Bad wireless module and other Bluetooth problems.
• Operating system malfunction.
• Driver related problems.
• Malicious programs actions.

As trivial as it may be, first check if the device is connected to the port and whether the plug fits snugly into the socket. It often happens that someone or you yourself accidentally pulled out the cord or wireless adapter.

Reason 1: Sensor contamination

With prolonged use, various particles, dust, hairs, etc. can adhere to the mouse sensor. This can lead to the fact that the manipulator will work intermittently or "brakes", or even refuse to function. To fix the problem, remove any excess from the sensor and wipe it with a cloth dampened with alcohol. It is not advisable to use cotton pads or sticks for this, as they can leave fibers, which we are trying to get rid of.

Reason 2: Connection ports

The USB ports to which the mouse is connected, like any other system component, may fail. The easiest problem is the usual mechanical damage due to long-term operation. Less often, the controller fails, but in this case all ports will refuse to work and repair cannot be avoided. To solve this problem, try connecting the mouse to a different connector.

Reason 3: Device malfunction

This is another common problem. Mice, especially cheap office ones, have a limited resource of work. This applies to both electronic components and buttons. If your device is more than a year old, then it may well become unusable. To test, connect a different, known working mouse to the port. If it works, then it's time to go to the trash can. A little advice: if you notice that the buttons on the manipulator start to work "every other time" or the cursor moves around the screen in jerks, then you need to buy a new one as soon as possible so as not to get into an unpleasant situation.

Reason 4: Problems with the radio module or Bluetooth

This section is similar in meaning to the previous one, but in this case the wireless module, both the receiver and the transmitter, may be faulty. To check this, you will have to find a working mouse and connect it to your laptop. And yes, do not forget to make sure that the batteries or accumulators have the correct charge - this may be the case.

Reason 5: OS failure

The operating system is a very complex complex in every sense, and that is why various failures and malfunctions often occur in it. They can have consequences in the form, including the failure of peripheral devices. In our case, this is simply disabling the required driver. Such problems are solved, most often, by a banal OS reboot.

Reason 6: Driver

A driver is a firmware that allows a device to communicate with the OS. It is logical to assume that its malfunction may lead to the impossibility of using the mouse. You can try to restart the driver by connecting the pointing device to a different port, and it will be reinstalled. There is another way to restart, with "Device Manager".

Reason 7: Viruses

Malicious programs can significantly complicate the life of an ordinary user. They can affect various processes in the operating system, including the operation of drivers. As mentioned above, without the normal functioning of the latter, it is impossible to use some devices, including a mouse. To detect and remove viruses, use special utilities, which are distributed free of charge by the anti-virus software developers Kaspersky and Dr.Web.

There are also resources online where trained specialists help to get rid of pests for free. One such site is Safezone.cc.

Conclusion

As it becomes clear from everything written above, most problems with the mouse arise due to malfunctions of the device itself or due to software malfunctions. In the first case, most likely, you just have to purchase a new manipulator. Soft problems usually do not have serious reasons and are solved by rebooting the driver or operating system.

It is impossible to use a laptop without a mouse or touchpad, so when a problem arises with them, people immediately wonder what to do. The reasons for the breakdown can occur due to human fault or due to a software failure. Fortunately, any of these can be fixed fairly easily. It is enough to figure out why the mouse does not work on a laptop and get acquainted with the solution to the problem.

Let's consider all the possible causes of a malfunctioning mouse.

General breakdown

Most often, the mouse on a laptop does not work if the operating system crashes. This can happen to anyone, so don't worry. Usually, the problem can be solved by simply restarting the computer... This can be done either by key combinations on the keyboard, or by holding down the power button on the laptop and turning it on again.
If the mouse still cannot be used, then you need to do the following:
1. Go to "My Computer" - Properties.

2. Select the section Hardware - Device Manager - Mice.

3. If the driver is malfunctioning in some way, there will be a yellow rectangle with an exclamation mark.
You can fix this problem by downloading the new mouse driver from the official site or by installing from the media. The trouble should now be removed.

What to do if a wired mouse doesn't work

Nowadays, fewer and fewer people use a wired mouse, since it is not always convenient and quickly fails. However, there are still those who do not want to purchase the wireless version for some reason. It is they who may face the problem that the mouse has stopped working. It is impossible to immediately answer why this happened. First of all, you need to try connecting the mouse to another computer or laptop. If it works on it, then the problem is in a specific laptop.
What to do in this case:
First of all, you need to try connecting the mouse to a different USB port. This often helps to resolve the problem.

You also need to reboot the system because an unexpected crash might have occurred.
It is recommended to check the drivers and install new ones if necessary.
You can try to remove the mouse from the system, restart the laptop and reconnect it. In this case, the device will be re-recognized.

If the mouse does not work on a laptop and another computer, then it is better to throw it out right away and buy a new one. It could break down due to the wiring, a malfunction in the plug, or simply burn out. Trying to solve mechanical problems on your own rarely leads to a positive result, it just wastes time.

By the way, in rare cases, the mouse may not function due to static stress. To fix this, you need to turn off the laptop and disconnect the plug from the outlet, remove the battery, then press the power button and hold it for 30 seconds. You can now return the battery, turn on the device, and connect the mouse. It is likely that now it will work.

What to do if your wireless mouse is defective

A wireless mouse is comfortable in all respects, however, and problems can arise with it. They are most often caused by dropping the device, spilling a large amount of liquid on it, and old age.

However, there are reasons beyond the control of the individual that the wireless mouse does not work. It is about them that the conversation will go. Wireless mice need batterieswhich tend to fail.

They need to be changed in a timely manner for the mouse to function properly. It is possible that at the moment they are the problem. Therefore, you should try to replace them and check if the malfunction goes away.

You can also try plugging the receiver into a different port and check if the mouse is turned on. If it works, but constantly freezes and sometimes stops connecting, then it must be rebooted.

In the case when the wireless mouse does not work at all and none of the above methods helps, it needs to be replaced. For some reason, it completely failed, and trying to find out what exactly led to the breakdown is a waste of time.

Touchpad (touchpad) problems

Some people prefer to use the touchpad built into their laptop. It would seem that no problems should happen to it, but it happens that it does not work or is buggy. The solution methods that are recommended to use if the mouse stopped working will not work here. Therefore, you will have to use the methods applicable in this situation.

Answering the question why there were problems, mention should be made of the quality of the touchpad. It is likely that laptop manufacturers have saved on it, which is why various glitches occur. If he functioned for a long time without failures, and now for some reason he began to junk, then the problem may be primarily in the person.

If the cursor disappears from the screen at times, this is most often due to dirt on the touch panel. That is why it must be regularly wiped with a damp cloth so that it does not have various stains and seals. It can also be a problem if a person works on the touchpad with wet hands.

The problem may also be a driver malfunction. In this case, you need to download it from the official website and reinstall it. This is often what helps. Also, the touch panel may not work due to the fact that it was accidentally or intentionally turned off. Press the corresponding power button located on the keyboard. In extreme cases, a hardware failure may be to blame, and it can only be solved by handing over the device to a service center.

Why a wireless mouse or a wired mouse doesn't work is a pressing question for all laptop owners. All kinds of solutions to it are presented in the article. If they didn’t solve the problem, then it’s better to get a new mouse than puzzle over the problem. It is recommended to buy a high-quality device, and not a cheap one, since the service life depends on this. Remember to handle your mouse with care and not drop it.

We are used to interacting with OS Windows using a mechanical manipulator, simply a mouse. The mouse allows you to almost not use the keyboard, because using the mouse you can:

Manage system processes;
- perform almost any system operations;
- perform the functions of the context menu.

But what if the mouse suddenly stopped working? What if the manipulator does not respond to commands, twitches, does not perform the actions we need?

Mouse does not work: what to do

Physical problems

1. You need to check through which connector the mouse is connected to the system unit. This could be a circular PS / 2 inlet. In this case, it is better not to connect the connector when the computer is running, otherwise a short circuit may occur.

2. If the OS does not "see" the mouse, you need to turn off the computer without its help. To enter the "Start" menu, use the combination Ctrl + Esc or the Win button. "Arrow down" and Enter select "Shutdown", press the "OK" button.

3. Often the reason lies in the disappearance of the contact. To check this, unplug the mouse and plug it back in. Now turn on your computer. If everything works, the problem is solved.

4. If the mouse is connected via the USB port, then it can be connected without turning off the computer. If reconnection does not help, it is better to turn off the system unit, and then try another USB input. It happens that the mouse does not connect through another connector, then you need to connect it to some working PC and test it.

In the case when a 100% working computer "sees" the mouse, it is possible that the connector on your PC is broken or there is a problem with the software. To check the operation of the connectors and inputs, you need to connect other working mice to the PC (it is better to check both inputs - PS / 2 and USB).

Software errors

If all procedures with connectors and inlets, as well as other physical parameters, do not help, then the problem is probably in the software. Enter the "Control Panel". For this:

a) press the Win key, and then "direction arrows", Tab and Enter, in the "Start" menu, find "Control Panel";
b) then find the "System and Security" icon, - the "Hardware and Sound" tab;
c) select "Device Manager".
d) through the Device Manager, expand the list "Mouse and other pointing devices";
e) then turn on the Shift + F10 menu;
f) then "Delete".
g) restart your computer (below we have presented this process in the screenshots).

When turned on, the system will re-install the drivers on the newly detected device (that is, on the same mouse that we removed in the previous step).

Hardware compatibility errors

What if you installed new programs, connected new hardware, and the mouse stopped working. In such a situation, a hardware conflict is possible.

To fix the situation, you need to enter the system through safe mode. To start Safe Mode, restart your computer and press F8 when you hear a beep. Select "Safe Mode". Then click “Yes”. If the manipulator is functional, you need to remove recently installed programs. Now turn on your computer normally.

Also, the problem of hardware incompatibility can be solved by selecting "Load Last Known Good Configuration" in "System Restore". Here you need to set a restore point closest to the start date of the difficulties. If nothing happened, then choose a different time.

It is also possible to enter "System Restore" through "Safe Mode", then to continue working you need to click "No", then select a restore point.

Run troubleshooting

Windows has a "Troubleshooter" module. You can take advantage of its capabilities.

Using the keyboard, find the "Control Panel", the "Mouse" icon, the "Hardware" tab. Shift + Tab keys switch to "Diagnostics". Then "Next". To respond to system requests, you must use the Shift key. Diagnostics can help identify faults.

Other probable problems

If all else fails, then scan your PC for viruses. You can install AVZ4 or. Antivirus software can run on a flash card. True, you will have to prepare such a USB flash drive in advance, which is almost impossible. However, those antiviruses that are already installed must be run for verification!

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 still occasionally there are devices with a PS2 connector.

The first step is to check the health of the 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 computer components. There is a possibility that the mode affects and therefore Windows 10 sometimes "does not catch" clicks of the left button.

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 "Allow this device to be turned off to save power". Repeat these steps for each item in 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 bar in the upper right corner.

A window will appear with a list of basic and sub plans. 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 when typing. Have you ever been while typing on a laptop and accidentally touching 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 gamers who play on laptops with mice, and here's why.

It turns out that in some cases the function blocks the action of the buttons on a USB mouse. 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 delay function on the laptop can be disabled.

There are two categories of reasons why the mouse does not work from the computer - software errors and hardware failures. However, not every user can quickly and accurately establish the truth of the event. Therefore, we will consider in detail each of the main causes of failure and how to eliminate them.

Three most likely causes

So, if the mouse does not work on the computer, then, most likely, for the following three reasons:

• Mechanical breakdown. Optical, wireless or wired mice often break due to chip failure. A break in the wire or breakage in the connector of the device may also occur.
• The button and / or wheel ceased to function. Most likely, the reason lies in a mechanical breakdown, but there may be software violations after a virus attack.
• The device does not work in a specific application (game, program). In this case, you need to look at the settings of the application itself.

Button atrophy

It also happens that the wheel turns pages and documents, but the right mouse button or left button does not work. In the structure of the device there is such a particularly sensitive part as a micric. With its help, a signal is transmitted from pressing the mouse button itself. In this case, the micrik often simply breaks off. There are two ways to solve this problem - to solder a button or buy a mouse, and if you consider that the simplest computer mouse costs a penny, then many users prefer the latter.

Features of the mouse connector

The mouse can be connected to a computer via both USB and PS / 2 connectors. If your USB mouse doesn't work, the first thing to check is the LED. In the case when it is lit, but the mouse does not work, the operating system is to blame. On the other hand, if the device does not work and the sensor does not light up, the reason lies in a malfunctioning USB port.

If the mouse does not work well on the computer, you do not know what to do and how to fix it, then it is better to just buy another one, since diagnostics and repairs can cost more than purchasing a new one.

A computer mouse is a familiar and indispensable accessory for any user, not only for a PC, but also for a laptop or tablet. Any problems with it can interfere with your work or rest.

But, if a computer mouse suddenly stopped working, this is not a reason to throw it away and go for a new one. You can try to find and fix the problem yourself.

Causes of mouse problems

The reasons can be of two types - hardware (mechanical) and software. The first includes all possible mechanical damage to the mouse itself, wires, plugs and sockets, unreliable contact, contamination, as well as static voltage that can affect the operation of the device.

Software problems include problems associated with drivers (their absence, outdated versions), malware, software conflicts, and operating system malfunctions.

Mouse hardware problems

First, you should check the integrity of the device itself and the connection. If you've dropped or doused your mouse with liquid, this could be the problem. But even if you are sure that there was no mechanical damage, inspect the case and cable of the device. Make sure nothing is interfering with the optics. Check the battery of the wireless mouse.

For a USB mouse, try using a different connector. With PS / 2 it will be more difficult, since the system unit usually has only one socket for it. But if you have another computer at hand, check if the mouse will work there.

By the way, checking the mouse on another computer will allow you to determine with almost one hundred percent accuracy what the problem is - in the computer or in an accessory. Similarly, you can test another mouse with this computer.

Examine the socket on the system unit for dust, liquids, or other interference to contact. Make sure the plug of the mouse or Bluetooth transmitter is firmly in place, but without force.

Thoroughly clean the connectors from dust and wipe the contacts with a match with a thin layer of cotton wool dipped in alcohol or use other available means.

Carry out work on cleaning the connectors only after unplugging the system unit from the outlet or removing the battery from the laptop, as voltage may be applied to them even in the switched off state.

If the connectors are oxidized, then it will not work to clean them completely with alcohol. Repeatedly insert and remove the mouse plug into the oxidized connector until the contacts are rubbed into a clean state.

If the problem was not revealed during an external examination, it may be due to internal damage to the mouse. Carefully open the case of the device and inspect if the contacts have come off somewhere.

Also, it may be a wire break (you can ring it with an ohmmeter) and feel the wire along its entire length. This will allow you to find the break and repair the cord.

If the mouse as a whole works, but sticking keys have appeared, often accompanied by a double click with a single press, then you need to carefully disassemble it, clean it and bend the contact plate in the microswitches under the buttons.

If the wheel starts to junk on the mouse, which often causes reverse scrolling and weakening of cutoffs, then you need to rinse its mechanism several times with alcohol and drop a little bit of machine oil into it.

In most cases this is sufficient and the wheel will work for a long time. But, do not rush to collect the mouse and check its work. If the wheel mechanism is very loose, then you can gently tighten its metal frame just a little bit with pliers. Be extremely careful, with excessive pressure this mechanism can break.

It also happens that the mouse cursor starts moving around the screen itself. This usually indicates that the electronic mouse controller is malfunctioning. In this case, the problem is solved mainly by replacing the mouse and there is nothing you can do about it. But do not rush to write off the mouse for scrap, perhaps it will work fine on another computer, it happens. Also, such problems can be caused by a rug, try how the mouse works on a blank white sheet of paper. If normal, then change the rug, preferably a one-color without patterns.

Mouse software problems

If the mouse is intact and works with other devices, then the matter is probably in the software part. You can absolutely confidently state this if the other mouse behaves the same on your PC. But there are also exceptions when failures in the software part appear only with a specific mouse.

One of the signs of software problems can be spontaneous movement or, conversely, a delay in cursor movement, as is the case with problems with the mouse controller. In this case, it is difficult to distinguish a hardware failure from a software failure. But, if the hardware problems are not confirmed, then proceed to identify the software ones.

If before the mouse crashed, you installed some programs and updates, then the problem is almost certainly in them. Try to remove them or disable them temporarily if possible.

Be sure to check your computer for viruses and malware. I recommend using the free utility “Kaspersky Virus Removal Tool” for these purposes, the latest version of which can be downloaded from the official website of the anti-virus laboratory.

If the mouse does not work at all, then go to the device manager and check if the computer sees the mouse, USB controllers, there are no unknown and error-prone devices.

If the device is not recognized, a descriptor request failed, or something similar, then follow these steps.

1. Disconnect all peripheral devices, briefly disconnect the PC from the network, and after booting, connect the mouse and test it. Some devices such as external drives, modems and some other (possibly faulty) devices can overload the USB ports on power and the mouse starts to fail.
2. If the device is displayed with an exclamation mark, then go to the properties of this device, select the "Driver" tab and click the "Rollback" button (if it is active) or "Delete". Then from the Action menu select Update Hardware Configuration.
3. You can delete obsolete records about previously connected equipment (flash drives, modems, etc.). They often interfere and lead to failures connected to USB devices. To do this, go to the "View" menu and select "Show hidden devices". Find and delete everything you connected to the USB connectors. Don't worry, the next time you connect, the device you want will be detected and reinstalled, and the problem with the mouse will disappear.
4. If the problem with rolling back the driver and removing old devices has not gone away, then try updating the drivers on the contrary, especially for USB controllers. I recommend using the free Driver Booster utility for this.
5. Check the power settings. Typically, this problem occurs with laptops - to conserve power, they turn off the power to ports that have not been functioning for a while. You can fix this in the system settings. Go to Power Management - Power Scheme Setup - Change Advanced Power Settings - USB Settings. In different versions of Windows, you can enter the power settings in different ways; detailed information on this topic can be found on the Internet.

Wireless mouse problems

Most often, problems with the operation of a wireless mouse are due to a low battery. This is mainly expressed in the loss of connection, spontaneous shutdown or jerking in the mouse.

Even if you bought and installed a new battery, there is no guarantee that it is of high quality. It is advisable to check it with a voltmeter. The voltage should be 1.3-1.5V, otherwise the lack of power can lead to problems and the battery needs to be replaced.

Also, poor positioning of the transmitter can cause problems with the wireless mouse. For example, when connected to the rear connector of a PC, the signal can be severely drowned out by the metal case. Connect the transmitter either to the front of the case or via a USB extension cable. In the latter case, the receiver can be placed on the table right next to the mouse. It also saves battery power. Well, do not forget to use the switch on the mouse (if there is one).

If, after pulling out and reinserting the receiver into the connector, the mouse does not work, then try repeating this procedure with the mouse button held down.

Also, the problem may be in the interference from the Wi-Fi router. Disable it temporarily and try how the mouse behaves. If the problem disappears, you will have to select a channel in the router settings where Wi-Fi will not interfere with the mouse. First, try the most unloaded channels that can be found using the Wi-Fi Analyzer mobile application.

If all else fails

If the search for hardware and software problems does not work, the mouse still does not work correctly, then make a backup copy of the system and install a completely clean copy from the original image (as there may be tweaks in the assemblies that lead to various problems, including with the mouse).

If the problem appears on a clean system, then it is definitely a mouse problem and will have to be replaced. If installing a clean system solved the problem, then it's time to set up your PC again, you will already have a clean Windows.

This way you can solve almost any problem with the mouse. If you know other ways, write about them in the comments.

There are quite a few reasons why a computer mouse may not work and they can be divided into 2 groups - software and hardware.

Software problems include crashes caused by malware or viruses, damage to the mouse driver (control program), or freezing of the computer due to unsafe actions: opening corrupted files or files "infected" by computer viruses (pictures, videos, music, etc.) ...

And to the hardware one can be attributed to the breakage of one or more wires in the mouse cable (and often they simply break due to repeated bending-unbending of the cable). As a rule, the wires break near the mouse body itself. Also, hardware problems include poor contact in the mouse connector, debris getting into the mouse body, pouring coffee, tea, cola and other drinks into the mouse, which makes the mouse shorter and it may malfunction.

And also, if the mouse is already 8-10 years old, then mikriki (microswitches), especially the left one, often fail. The so-called bounce of contacts appears: you pressed, and instead of one clear signal, a burst of pulses went to the input of the PC, and the computer is often lost in guessing what you want from it - whether to open or close ... Or, there is no contact at all. .. This malfunction manifests itself in such a way that you cannot select the text and make many attempts (clicks) for this, or, look at the pictures, clicking, and they periodically slip through one or two, i.e. out of order.

To check if the mouse is to blame or not, you can plug in a known working mouse and see if the picture changes. If your guesses are confirmed, then you need to replace the mikrik, so do not rush to throw away your old mice without taking out the spare parts ... :)

If you recently bought a mouse, for example with a usb connector, stuck it in, but it does not work - the cursor is dead, then the reason may be the lack of necessary drivers in your Windows assembly.

So, let's take a closer look at all of the above typical cases of mouse malfunction. Most of these malfunctions can be fixed by yourself if you have at least a little skills in the repair and diagnosis of computer hardware.

If the cause of the malfunction is malware: you need to scan your computer with an antivirus, if this is not possible, restart it in safe mode (Delete or F2 button) and run the scanner of the antivirus program, thus cleaning it. your computer.

It didn't help - reinstall the mouse driver, the virus may have damaged it, if there is no driver, restore the operating system from an earlier copy.

If the mouse worked well and suddenly the cursor froze, it doesn't matter, just disconnect and reconnect the mouse connector, sometimes this technique helps. Or, restart your computer, it may just freeze - click the "Reset" button. There are also various mechanical reasons, some object (debris - fibers from clothes, fur, etc.) got into the mouse and closed the laser. And if you have been using the mouse for several years, then there is probably already a lot of this garbage ... In this case, you just need to disassemble the mouse and clean it, wipe it with medical alcohol (just not the optics).

It is also very desirable to do mouse prophylaxis, at least once every 2 years, especially if you use a computer intensively. When you turn the wheel, garbage (especially villi) is dragged in there, and after 1-2 years there will be a mountain of it, which is why the mouse may also glitch.

If the mouse twitches, it works, but not - the reason for this may be a break or breakage of the wires, as mentioned above. It is necessary to open the case of the mouse and ring the wire with an ohmmeter: on the connector and in the mouse itself, on the board - is there a break there. While dialing, move the cord, sometimes this is the only way to determine where and which wire has broken ...

Well, there are also the most commonplace reasons: when moving the computer to another place, pay attention - did you confuse the sockets - of the ps / 2 mouse with a round plug with the ps / 2 keyboard socket? With such varnishing, the keyboard and mouse do not work or the computer simply hangs ... The fact is that these slots are very similar to each other, and differ only in color. Mice are green, keyboards are purple, and the connectors must also be inserted according to the color.

Or, it happens that a mouse with a ps / 2 connector cannot be inserted into the slot. The reason is that you need to properly unfold the plug, see where the key is and then insert it! And attempts to insert it incorrectly lead to the fact that the legs of the connector are bent, or in the nest (in the mother) the peels are bent, and then it will not be possible to insert the plug already and correctly unfolding the plug ...
What to do? Take a magnifying glass, a flashlight, carefully inspect the connector and align everything.

As for the wireless mouse, there may be the following additional reasons: the batteries sat down or leaked (do not buy cheap batteries, they leak ..), the receiver is out of order, the driver is damaged, or there is simply no contact in the connector (oxidized - you need to move or remove and insert), etc.

Special problems arise with the USB mouse. The need for a USB mouse for a PC often arises when it is impossible to connect a ps / 2 mouse, i.e. the ps / 2 connector in the system unit broke, or, for some reason, you got a good and comfortable mouse, but here's the problem - it turned out to be with a usb connector.

Usually, Windows assemblies (Windows installation discs) have drivers for a usb mouse in their kit, but they may not be in old assemblies of operating systems ... And if your computer is old, then you will not stick a newer operating system into it, so you have to look for driver ...

If the USB mouse drivers are present in the Windows assembly, then it is very simple to connect such a mouse - insert it into the USB connector, the operating system detects the device, connects it, and will give you a message that the USB mouse is ready for use.

Otherwise, it is not always possible to understaff the Windows assembly, especially if you, as a system administrator, are not very ... The first thing to do for this is to go into the BIOS and set the permission for USB mouse connections. The second is to try to find a driver for a specific mouse model on the Internet and install it. And be sure to restart your computer after installing the driver.

USB mouse still not working? There is another simple and reliable way, but you need an installation disc with the drivers we need. No, an attempt to isolate the drivers from there and install them on your Windows will not lead to anything, at least I did not succeed, but updating Windows from this disk yielded a result. After updating so. operating system, the universal driver was installed and the USB mouse worked without problems!

Of course, if you bought a 6-button mouse, then perhaps all the buttons will not work after the OS update, but only the main ones, then you will need to additionally install the driver of this particular mouse model.

The mouse buttons (left and right - mikriks) may still not work due to the fact that dirt has got into the mikrik's case and they just stick. This is usually a grease that hardens and becomes sticky over time, or spilled coffee or tea. In this case, you just need to clean the mouse (rinse the case) and mikriki - wrap a cotton swab on a match, moisten it slightly with alcohol and rinse, wipe thoroughly, dry, and everything will function. It happens that the mikriki are simply worn out, especially the left one, and it is buggy, then it must be replaced. By the way, as a rule, mikriki can be taken from any old mouse, even those mice that do not have a laser - with a ball are suitable.

If you removed the mouse from the connector, inserted it and after that it refused to work - restart the computer so that it updates the data. In some cases, this helps.

And by the way, the mouse pad can also cause poor mouse performance, try changing it if the mouse does not work well. Although, when buying, you need to choose a mouse that would not be capricious to the rugs ... tell the seller to connect it to your laptop, and try in real life how it works - just on the table, and then on the rug, etc. I have personally tried different rugs, and the most durable was the leather rug, which has been around for about 10 years. It often happens that having done prophylaxis to your old mouse, it works even more clearly than the new one. And your hand is used to it ...

As you can see, fixing a computer mouse with your own hands, or making it work, is not so difficult, at least in most cases.

What else I want to add. Now they have already started making and selling mice with built-in drivers very actively, the driver is stored in the memory of the mouse. You inserted the mouse connector into a PC or laptop, immediately the computer determined what kind of device it was and loaded (you will be given a message that the driver is loading), and installed its native driver from the memory of the mouse. Very convenient and removes many problems. I know for sure that such companies as SVEN, HP were among the first to use this technology. So, when buying a mouse, ask if the driver is built-in there.
