In this article we will try to give the most complete answer to the question why the mouse does not work and we will try to answer all related questions, such as: why the touchpad on a laptop or a wireless mouse may not work.
Almost every user sooner or later encounters such a problem as problems with the computer mouse. This can happen for many reasons, which, in turn, can be divided into two groups, depending on the source of the problem: hardware or software. What are these reasons, and how to eliminate them?

Reasons why the mouse may not work

Software

TO software problems can be attributed:

• Problems associated with the harmful operation of viruses,
• failures or damage to the driver, as well as in case of opening damaged files, archives.

Hardware

Hardware problems are problems caused by damage to the mouse itself. These include:

• Wire deformation;
• Contacts are damaged or clogged with debris.

It often happens that a user, while working at a computer, drinks tea, coffee or some other drink and spills the liquid. This often results in the mouse being disabled.
By purchasing new mouse with a USB input, and if you find that the cursor refuses to move after connecting the device to the computer, do not rush to sound the alarm. Most likely, the installed operating system does not have the necessary drivers.

Troubleshooting solutions

The good news for all users is that it is quite possible to cope with most malfunctions on your own. To do this, it is enough to have at least basic knowledge about the work of the hardware. So, the action plan is:

• First of all, check your computer for viruses or other malware. You can do this using free antivirus programs, for example Avast.
• If this does not help, then proceed to the next step: reinstall the mouse driver, which could very well be infected with a virus.
• If this is not possible, try restoring previous version OS (operating system). How to do this in the video below:

Why the mouse does not work on a laptop: common reasons and ways to solve them

Reasons Why doesn't the mouse work on a laptop? there may be many. But this trouble is easily eliminated. First you need to determine what type of mouse is used for the laptop (touchpad, wired or wireless). Each type has its own characteristic causes of problems and ways to solve them.

Touchpad not working on laptop

If problems arise with the operation of the touchpad, they can be solved by correctly identifying the cause of the problem. So, the most common situations:

• Incorrect operation (freezes, interruptions, cursor disappears from the screen).
• The reason may be incorrect setting parameters. When installing, it is recommended to use the included driver.
• Besides, Special attention Pay attention to the cleanliness of the touchpad - simple surface contamination reduces the sensitivity of the device.
• It is forbidden to work with wet hands. To fix this problem, just clean the sensor from dirt and let it dry completely.
• The device does not respond.

The reason is that the panel is disabled. Solutions:

1. if present, check the on/off button;
2. some models turn off touchpad when connecting external device(wired or wireless mouse) – disable the additional pointing device;
3. V BIOS settings enable the support function for this panel (the enabled value for the Internal Pointing Device parameter).

If the problem cannot be resolved, you must contact the technical support center.

Reasons Why don't my mouse buttons work on my laptop? There may be problems with the mouse itself or a failure of the USB port, as well as incorrect connections and settings. To check, connect the mouse to a different socket or to another computer. If everything works, then you need to clean the input channels. Do not use long-haired rags or cotton wool as cleaning materials, and do not overdo the material with moisture. If the mouse does not react, it cannot be saved.
Demon wired mouse is becoming increasingly popular among users. The main problems with this type of mouse are:

• Complete lack of response to manipulation;
• Slow operation, freezing or slowing down.

The reasons for this may be:

• the mouse is not connected (insert the adapter (USB receiver) into the USB port and turn the button on the mouse body into working condition);
• The batteries are low (replace with new ones, and correct operation will be ensured again). The reason is quite banal, but many do not even suspect that the mouse is powered by batteries.
  It is recommended not to use regular batteries, and batteries - this will prolong the operation of the device. In addition, if the manipulations described above did not help, you should check the functionality of the USB port to see if it is dirty. Perhaps the mouse itself is faulty. In this case, there is only one way out - replacing the mouse.

The mouse may not work also in individual applications, but this is an individual story for each application. In the meantime, as an example, here’s a video with a solution to the problem why the mouse doesn’t work in the GTA game:

How to troubleshoot mouse problems

Troubleshooting
in mouse operation

If your mouse starts to work poorly, don’t rush
run to the store for a new one, and try to “cure” the old one.

First of all, make sure
that there are no problems in the mouse itself.

If wired, is the wire damaged?
If it’s wireless, isn’t it time for a battery?
change or fix the USB connector.

If this is all right, then connect to the Windows problem.

There are many ways to improve your mouse's performance on your computer.
Can configure mouse operation“to suit you” or change the signs.

And you can troubleshoot
or update the configuration.

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

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

IN right column Start button menu, if available,
select “Devices and Printers”.

A window will open containing 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 “Hardware and Sound” section -
"View devices and printers" button.

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).

To troubleshoot, click
by mouse file to select.

If there is no File button in Explorer, then right-click
mouse file key. Will open context menu.

(Click on the picture to enlarge)

And select “Troubleshooting” from the context menu.
Wait while the troubleshooter diagnoses the problem (this may take a few minutes), and then follow the instructions.

Although there may not be instructions.
If the problem is resolved without your participation.
At the bottom of the window will appear active button"Complete".
Press and to correct operation mice,
reboot your computer.
All!

How to update your mouse configuration

If the troubleshooter doesn't help
problem with the mouse - you can update the configuration.

This can be done through Device Manager.
You can find it through the Start button.

Start → Control Panel → Hardware and Sound.

(Click on the picture to enlarge)

Under Devices and Printers, click Device Manager. A tab like this will open.

(Click on the picture to enlarge)

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 left mouse clicks. I myself recently encountered this phenomenon.
The mouse pointer moves across the screen, left mouse It clicks but nothing opens. No windows, no Start - nothing. Right mouse The context menu opens, but the left one cannot open anything from this menu. Neither an emergency shutdown of the computer, nor all kinds of advice from the Internet (about Enter key and “hot keys” Ctrl + Alt + Del) did not help solve the problem. At first I thought there was a problem with the computer, and then I connected another mouse. And after Windows installed the driver for this mouse, everything worked properly.

To identify the reasons why the mouse does not work on a computer or laptop, you must do a few initial checks. They are all very easy and can be completed in a few seconds.

Why the computer mouse does not work - the main reasons

First: the reason is the batteries. If your mouse is wireless, then change the batteries.

Although its bottom still glows red and flashes, this does not necessarily mean that it is still functional.

Second: dust. Clean the bottom with a clean cloth and make sure there are no dust particles affecting its performance.

If you have followed all these steps and the problem persists, below are the most common problems and their solutions.

Reason one

The mouse cursor does not move smoothly. SOLUTION: If the mouse cursor does not move smoothly, the most likely cause is dust in the mouse sensor or on the surface, be it a rug or table.

Clean thoroughly with a clean cloth and no chemicals that cause more problems.

Reason two

Another factor that could be causing this problem is that you are using the mouse on a glossy surface.

Some mice, especially optical and laser mice, have difficulty tracking on glossy surfaces such as glass. Try using matte surfaces instead.

Reason three

Problem: The mouse pointer freezes. SOLUTION: Most probable cause this problem is related to central processor your computer.

In this case it can be launched more programs than necessary or background applications, and at the same time you may not even realize it.

This is of course very annoying. What to do? Wait a few seconds - these are the simplest solutions and often the best.

Just wait a few seconds to see if the problem resolves. If it is not eliminated and recurs, then further research is necessary.

Some computer programs work in background without your knowledge (you don't even see them).

Look in the lower right corner of the worker Windows desktop(), if there are unnecessary ones, then turn them off, and if they are not needed at all, then delete them completely.

Reason four

The mouse doesn't work at all. SOLUTION: This can happen from various problems. Some of these may be software and hardware related.

The mouse may not work as a result of a poor connection, faulty wiring, or faulty USB port.

Double check the integrity of your ports and ensure they are fully functional.

Some wireless devices (and some wired ones) require driver installation. Make sure it is installed.

Reason five

PROBLEM: The mouse pointer moves too slowly or too quickly.

SOLUTION: For this problem, there is only one solution in configuring the software.

This can be easily fixed by going to => Mouse => Pointer Options =>.

Change the cursor speed to required level, moving the slider up or down until you feel comfortable working. Good luck.

If you are faced with a problem where the mouse on your laptop does not work, do not despair, because often the problem is not difficult to fix and you can do it yourself.

Many users, when problems arise with a computer mouse, prefer to contact workshops, most often due to the relatively low cost budget models just buy a new one.

Don’t rush to go to the store, take a little time, and we’ll tell you what to do if the mouse on your laptop doesn’t work.

Reasons why it doesn't work computer mouse not much, but initially you need to decide on the initial data:

what type of control is used (mechanical, optical)?

Connection method to laptop (wired, wireless)?

What interface does it use to connect to the computer (PS/2, USB)?

What to do if a wired mouse does not work?

However, the thing to keep in mind here is that a USB mouse, unlike a PS/2 mouse, is a plug-and-play device. What does it mean?

Based on the main concept of Plug-and-Play devices, they do not require additional configuration/

The operating system automatically, on the fly, recognizes objects and makes changes to the overall configuration.

Thus, in the case of a USB connector, configuration changes will be made automatically without the need to restart the laptop, and in the case of a PS/2 connector, a reboot is not necessary.

If all else fails, try rebooting regardless of the interface you are using.

In some cases, this method is effective and efficient.

Also try removing the USB mouse, rebooting the laptop, entering your username and password to enter the operating system, and only after loading, insert it into one of the USB interfaces.

Next, you should try changing the connection interface on the laptop; perhaps one of them is not working correctly (“burned out” or frozen), this is a fairly common reason, perhaps the most common among the rest.

The ideal option would be when you have the opportunity to replace the mouse with the same one, in whose performance you are 100% sure.

In this case working model should be inserted into the slot in which the current one is installed.

Remember the difference in interfaces described above and if you install a device with a PS/2 interface, do not forget to restart the laptop.

It's also a good idea to test your mouse to see if it works on another computer, not necessarily a laptop.

Everything is simple here if you inserted working device into the laptop and it doesn’t work, the problem is definitely in the laptop.

If your mouse does not work with a laptop, but works on another computer, the problem is again with the laptop.

In some cases, the mouse may not work correctly, which manifests itself as slow cursor movement or periodic lack of communication with the mouse.

Static voltage as one of the reasons for a non-working mouse

In some cases, the device may not work as a result of static charge accumulation. Also, quite often, USB interfaces burn out for this reason.

Let us note the fact that this problem typical for both wired and wireless mice. The solution to this problem is to remove the existing static voltage.

To do this, follow the steps below:

Turn off your laptop.

Press and hold the laptop's power button for at least 30 seconds.

Install battery.

Turn on the power of the laptop after establishing a connection to electrical outlet.

Turn on your laptop, go to operating system and check the functionality of the mouse.

What to do if your wireless mouse doesn't work?

The first and most common reason why a wireless mouse refuses to work is dead batteries. .

To test this thesis, insert other working batteries into the wireless mouse.

Please note that the batteries may not be completely discharged and may even work in other devices (such as the remote control), but the mouse will not work.

In some cases for wireless mice freezing is typical.

To get her out of this state, use special button turning on/off the mouse - turn off the mouse and turn it on again after a few seconds.

Usually, this button located under the arm, in some cases it is represented not by a button, but by a lever.

A wireless mouse is a very convenient device; you must agree that the absence of an extra wire will not at all interfere with working at the computer, but on the contrary will make your time spent more comfortable. When problems appear with the mouse, users panic a little, thinking that they need to change the mouse. But in fact, the problem may lie not only in the mouse, so we will now figure out why the wireless mouse on a laptop or computer does not work. Before you run to the store for a new mouse, I strongly advise you to read this article. It will help you identify typical problems, which can arise at any time for any user and which can be dealt with in just a couple of minutes. As usual, I will tell you everything in detail and explain with examples.

First of all, if this is possible, connect the wireless mouse to another computer or laptop. Works? So that's clearly not the problem. Try inserting the USB signal receiver into a different connector. If you have a computer, then connect the mouse from the back, and not from the front, as was usually done before. If you have a laptop and there are USB connectors on the left and right, possibly also on the back, then try connecting the mouse from different sides.

Fast decision

Now we will produce automatic elimination Problems. This way, you won’t have to figure out why your wireless mouse isn’t working. To do this, follow the link. A window will appear that you do not need to close; click on the “Run now” link. After which the download of the utility will begin. Now launch it, click “Accept”.

Don’t click anything, wait for the next window.

You will be asked to produce different actions, for example, enable Wi-Fi if it is disabled, install the driver if it is not installed, etc. Before you click Fix, read what exactly will be fixed. This utility is not a solution to all ills, do not think that this Magic wand, although sometimes it is extremely useful.

Many users forget that wireless devices operate using batteries. Therefore, if the wireless mouse does not work, then pay attention to the batteries, they may be dead. Do not look at the backlight indicator (laser) at the bottom of the mouse. The voltage from the batteries may be enough to power it, but not enough for the rest of the full work. When the mouse starts working every once in a while, this is a sign that it needs to be replaced. If, after purchasing new batteries, the mouse refuses to work, then the matter is different and you need to understand further. Also very common problem– this is a clogging of the laser in the mouse. In this case, it can be gently wiped with a cotton swab or ear cleaner.

You can disassemble the mouse if you definitely think that the problem lies in dust and dirt. Any computer mouse can be disassembled simply, on an intuitive level (as a rule, it is enough to unscrew a couple of screws and then screw them back). Turn the mouse over where the laser is located, make sure that the mouse is turned on - the “ON” position. Also below there is Reset button or Connect, click on it and check the mouse.

Software problems

You may have recently installed programs that affect the operation of a wireless mouse. Remember what software installed on your computer. If this is the case, then try removing it, restarting the computer and reconnecting the mouse. Did the mouse work? Then you need to understand this program. If you've tried everything, but still don't understand why your wireless mouse stopped working, then it's worth a look Windows settings and understand why the wireless mouse on your computer does not work.

We are trying to bring the mouse back to life programmatically. Connect any simple mouse to your computer or laptop in order to perform the steps described below. You can do them without a mouse using the keyboard and hotkeys. Make sure it is connected via USB receiver to a working port (to be sure, check the port for functionality by connecting, for example, a flash drive, etc.), then go to “Start” - “Control Panel” - “Hardware and Sound”. In the “Devices and Printers” section we are specifically interested in the “Device Manager” inscription, click on it and the corresponding window opens in front of us. We are looking for “Mice and other pointing devices” here. Expand this thread and click right click mouse using the name in the list (this is your mouse), select “Engage”. This option may not exist - then click “Disable” and then “Enable”.

And that's all I have for today. I sincerely wish you good luck with your wireless devices and I think that you managed to solve the problem when the wireless mouse does not work.

The tournament will end soon, there is only 1 puzzle left.
