Why doesn't the mouse wheel scroll down the page? Why the mouse wheel doesn’t work: how to fix it and what to do? Changing mouse settings

Sometimes such a useful gadget as a computer mouse malfunctions, the occurrence of which is impossible to predict in advance. This glitch occurs when the mouse wheel suddenly, for no apparent reason, stops scrolling pages of information both up and down. What to do about it? This will be discussed further below.

The easiest way to check the functionality of the “electronic rodent” is by going into a text editor like Word. If everything works fine there, you can calm down. However, not everything is as simple as it is described.

Changing mouse settings

To understand the problem from the inside, you should look at the image below:

This screenshot shows where to click if there is no mouse movement or page arrows. To make it more clear, it is worth duplicating the entire process from the very beginning.

1. First of all, you need to go to the Start menu by selecting Control Panel.
2. In the Control Panel, select the “Hardware and Sound” tab.
3. Next, click on the “Devices and Printers” button, and then “Mouse”.
4. In the mouse settings, you need to select the “Wheel” tab, after which a scale will open, where you need to increase the slider to the maximum and click the “OK” or “Apply” button.

Now it's time to test the changes. If everything remains the same and all operations did not help, it is recommended to reinstall the mouse software driver.

Reinstalling drivers

If necessary, reinstalling the mouse driver will only take a few minutes for a confident computer user. In order to complete the update, you must follow a certain procedure:

1. First you need to open Windows Device Manager;
2. Next, you need to carefully look at the entire menu and find there an item called “Mice and pointing devices”;
3. Now you should find the mouse you are using, double-click on the name and select “Update device driver” or similar.

If the update does not have the desired effect, you should not despair; you need to follow the same path as when installing the update, but at the end click “Remove driver”. After complete removal, the device driver must be reinstalled.

Disassembling the mouse

It also happens that when you scroll through the special side sliders with the mouse, the pages “jump”, changing position up and down and back. This scenario of mouse behavior indicates a malfunction of the touch sensor. To fix this problem, you need to do the following:

• First, you need to correctly disassemble the mouse by removing the case and bending the protective “petals”, acting strictly according to the instructions.
• After the first stage of disassembly is completed, you need to carefully remove the protective casing, which protects the scrolling mechanism itself from damage.
• Now you need to remove the clamping mechanism from the mouse wheel as carefully as possible, treat it as thoroughly as possible with an alcohol-containing compound and allow the parts to dry thoroughly. It is best to wipe all components not with a piece of cloth, but with a cotton swab.
• Next, you should pick up the pressing part of the mouse and press with moderate force on the middle until you get a small dent. As soon as this dent appears, you can consider the mouse repair complete and begin assembling the product.

In the event that even complete repair and reassembly are powerless, you need to contact a service center for professional service by a technician, or simply buy a new mouse and configure the parameters correctly.

Lubricate the mouse

It also happens that during use the mouse either does not spin at all, or rattles very loudly and creates noise when the wheel is scrolled. In this case, the issue is not a software failure, but a hardware malfunction. To begin with, it will be enough to lubricate the scrolling mechanism with a special silicone-based gel. An excellent example of such a lubricant is WD-40. To check, you need to drop a few drops of lubricant inside, assemble the wheel and scroll 2-3 times.

If all the described methods did not help, you need to do this:

• disassemble the mouse by removing the wheel from inside;
• carefully separate the petals protecting the “filling” of the mouse from each other;
• twist braces of suitable diameter from copper fishing line;
• carefully solder the brackets, placing each one in place of the petals;
• assemble the mouse completely.

ADVICE! If you have a warranty card for the mouse, it is better not to take risks, but simply send the gadget in for repair, fully explaining the situation.

Reassigning keys

If the mouse refuses to function when you press the wheel, you need to look for the “root” of the problem in the hardware settings. Usually, with this kind of malfunction, slightly strange clicks may be heard when pressing the wheel. To eliminate the problem of characteristic clicks, you will need to download a specific application for reconfiguring active keys AntSoft Key Manager and install the full version. The Oscar program has the same functionality.

Now you should find out which function in this customizer is responsible for the operation of the buttons and mouse wheel.

If the wheel does not work only when launching games, then there is no need to rush to download repair software, but just make changes to the settings of the game itself. If, when you press the mouse wheel, you cannot hear a peculiar click at all, you should not repair the mouse yourself, but rather replace it.

Resolving the conflict between the driver and the system

In the case when a person uses the Windows 10 operating system, there may be a conflict between the operating system and drivers selected incorrectly by the user.
When faced with this problem, you need to open the OS update center, then click on the “Search for updates” button, after collecting information you should click the “Install” button, and then simply restart the computer, which will help the updates take effect.
Usually this repair method turns out to be quite effective, but there are exceptions that only a master can deal with.

Users don't realize how important the mouse wheel is until it becomes unusable. Meanwhile, it is the wheel that is responsible for scrolling pages, changing the scale in editors and browsers, opening a page in a new tab, as well as some gaming functions. What to do if the wheel doesn't work? Don't rush to change your mouse - try troubleshooting.

How to fix a mouse wheel

The key causes of problems with the wheel are malfunctioning software or mechanical damage to the mouse. If you detect a failure, first connect the accessory to another computer and check its functionality. If scrolling works, the reason is in the settings, and if not, the solutions vary for each specific case.

If pressing and scrolling up and down does not work

A mouse that does not respond to clicks or scroll the wheel must be disassembled to understand the cause of the failure. Procedure:

1. Remove the protective pads at the bottom of the mouse and unscrew the bolts.
2. Detach the bottom panel. You will see a board, and below it is a scroll mechanism.
3. Lift the board after unscrewing the bolts.
4. Take out the wheel and pay attention to the axle - most likely, it is broken off on one side.

If you find a broken axle, try to fix it using a paper clip:

1. Unbend the paper clip, bend the wire in half and twist it into a bundle.
2. Attach the part to the wheel, in the place where the axle was located, and cut it to size with pliers, adding 1-2 mm.
3. Heat the desired part of the wire red-hot on a gas stove or using a piezo lighter and apply it to the fracture site of the axle.
4. Once the material has melted, reassemble the wheel and check for scrolling and pressure.

Photo gallery: how to disassemble a mouse yourself

Step 1. Remove the base of the mouse Step 2. Remove the wheel Step 3. Replace the wheel axle Sometimes it is not the axle itself that breaks, but the tabs that hold it in place

If the mouse works and the wheel spins evenly without hitting anything, reassemble the case and check the functionality.

Sometimes the axle does not break off, but falls out. If you find a pin that has fallen out, replace it with a larger diameter axle.

Pages won't scroll

Check your software settings if the mouse does not scroll the page. For this:

1. Open "Start - Control Panel". Select "Hardware and Sound - Devices and Printers - Mouse".
2. Open the Wheel tab and check the scroll values.
3. Increase the values ​​if necessary and click OK.

There should not be zero values ​​in the settings

Check the operation of the mouse - if the method does not help, reinstall the driver. Sequencing:

1. Open Device Manager.
2. Find Mice and Pointing Devices.
3. Select the mouse you are using and double-click on its name.
4. Open Driver and click Update.

Select the problematic mouse from the list

If the update does not bring results, follow the same path and click “Uninstall”, and then reinstall the driver.

If the pages “jump”

In a situation where the wheel works, but when scrolling quickly the page turns jerkily and “jumps” up and down, the touch sensor is faulty. To fix it:

1. Disassemble the mouse using the instructions above.
2. Remove the protective cover from the scroll mechanism.
3. The sensor is pressed to the wheel by four metal petals - carefully bend them one by one.
4. Bend the protective part of the wheel, remove the clamping mechanism and wipe it and the inside of the device with a cotton swab dipped in alcohol.
5. Place the clamping piece on the table and press on the middle with a screwdriver so that a dent remains. It will guarantee the correct operation of the part when scrolling.
6. Place the mechanism in place, bend the protection and press the petals back tightly.
7. Assemble the wheel, replace the board and the lower part of the case. Secure the parts with bolts.

The indentation in the middle ensures clear scrolling

Check the functionality of the mouse. If scrolling does not work, contact service or replace the mouse.

The wheel does not spin and rattles

When the wheel does not scroll at all, or something rattles inside the mouse, look for a hardware failure. First of all, lubricate the mechanism. To do this, disassemble the accessory as described above and clean the sensor with alcohol. Prepare liquid silicone lubricant - for example, WD-40. Drop it inside, assemble the wheel and spin it two or three times. Check the operation - if lubrication does not help, replace the pressure petals. For this:

1. Disassemble the mouse and remove the wheel.
2. Break off the petals holding the protection.
3. Use copper wire to make 4 brackets of the appropriate size.
4. Solder the brackets in place of the petals and assemble the mouse.

By disassembling the mouse yourself, you automatically lose your right to warranty service.

Iron brackets are soldered to the sensor

Pressing the wheel doesn't work

If the mouse wheel scrolls pages, but the system does not respond to clicks, listen for clicks when clicked. If yes, check the program settings:

1. Download an app to reassign hotkeys - Antsoft Key Manager or Oscar.
2. Find out what function is assigned to the wheel click.

If the click function does not work only in the browser or game, you do not need to download additional applications - check the information in the program settings.

If the click is not heard, the problem is a hardware failure. Disassemble and repair the mouse or replace it with a new one.

Conflict between Windows 10 and mouse drivers - how to fix it

In Windows 10, scrolling works in Explorer, browsers, editors and the standard environment, but in the Start menu and some pre-installed applications it does not. The reason is a conflict between the system and device drivers. When faced with such a problem, install Windows updates. For this:

1. Open Update Center and click Check for Updates.
2. When the system collects information, click “Install updates.”
3. Wait for the process to complete and restart your computer.

The method may not help - in this case, do the same steps and roll back the update. If working with updates does not bring results, download mouse drivers from the official website. Try combinations:

• system update + new driver;
• system update + old driver
• system without updates + new driver.

If the problem persists, contact Windows technical support.

Problems with the mouse caused by glitches in programs can be resolved independently. Hardware failures, including those related to the mouse wheel, should be fixed by yourself only in cases where you are technically savvy and are not afraid of losing the warranty on the gadget.

The weakest point of a modern computer mouse is the scroller, the scroll wheel. Sometimes the wheel breaks down within the first week after purchase. Scrolling becomes capricious, does not work for a short rotation, scrolling accuracy is lost, large gaps occur during intensive scrolling, etc. And sometimes it happens that the window scrolls in the opposite direction!
This will throw anyone out of balance.

Mother! She won't scroll! Again!!!

If you have 15 free minutes, then you can try to fix the mouse using a minimum number of tools. And you don't need a soldering iron here!
Even if you have absolutely no skills in “tinkering” with electronics, I recommend that before throwing away the mouse, try to fix it and gain at least minimal experience. First of all, disconnect the mouse from the computer!
Take a thin Phillips screwdriver and disassemble the mouse. Sometimes manufacturers cleverly hide screws under sliding pads.
Happened? Now take a look at your mouse. Most often there are two main designs.

1. Mouse with optical scroll wheel sensor

The photo shows a mouse in which the scroll wheel is built on an optical encoder. This is usually a sign of more expensive and high-quality mice. Distinctive features are a ribbed partition inside the scroll wheel and 2 optical elements (emitter and receiver) on opposite sides of it.
In this case, repairs are simplified. It is necessary to clean wound hairs, wool, threads from the roller axis, which impede the uniform rotation of the wheel and block the operation of the optical system. If necessary, wipe off any dust, dirt, or stains from the emitter and receiver.

2. Mouse with mechanical scroll wheel sensor

But mostly manufacturers make mice using electromechanical encoders in order to reduce the cost of the product. Next, we will consider in more detail the case of failure of such an encoder.

We remove all unnecessary things and see an electromechanical encoder, which is a bit like a tuning resistor. Here it is, with an orange octagon inside.

If you have a soldering iron and the accompanying skill, it is better to unsolder it for further disassembly and cleaning. Otherwise, you need to be very careful to avoid breaking the contact leg when bent.

Carefully bend the insides away from the frame, and if you have unsoldered the encoder, then simply disassemble it. The metal retainer is usually mounted on plastic legs. Everything is removed very easily, the main thing is to work without fanaticism.

And we see inside the true reason for the failure of the scroll wheel: the same garbage and dirt. Most likely it is a mixture of silicone grease, ground dust and hairs. The contact springs are also covered in dirt.

We take cotton wool, dip it in alcohol (isopropyl or ethyl), vodka, beer or special drink. cleaner for electronic contacts. It is better not to use acetone, because... there is a risk of dissolution and deformation of the plastic parts of the encoder.
Next, carefully wipe the contact pads and springs. Be very careful when cleaning the springs, otherwise you may ruin everything.

I think the difference is obvious. Look how much dirt has collected on the cotton wool.

Tweak the elasticity of the scroll wheel

If you want the roller to be more elastic, and its fixation when scrolling to become more rigid and clear, then you can make a small modification.
The metal retainer, which helps secure the wheel, is shaped like a semicircle. Using very thin pliers or tweezers, you need to bend it along the middle of the radius to form a sharper protrusion.

Now the protrusion will fit more tightly between the teeth on the plastic ratchet.

We put everything back together in reverse order and you can continue to use the mouse.

Results

I have already cured many mice this way. Moreover, the cheapest mice, oddly enough, turned out to be the most reliable.

For example, in the photo, the long-range Gembird mouse is the cheapest, bought in transition, has been working without jambs for 2 years, while the left “gamer” Trust, which is 15 times more expensive, had a scroll wheel that got dirty just a week after the purchase.

Happy repairs and strong mice!
Thank you for your attention!

Hello everyone, friends! I am sure that the wheel on your mouse does not work, is that why you came to this article? How convenient it is to work at a computer with a mouse, and what disappointment we experience when some problems appear in it at the most inopportune moment. In this article we will troubleshoot problems if the mouse wheel does not work or scrolls. And the reason for this is not necessarily a bad manufacturer. It’s just that each thing has its own service life and one day it ends.

The mouse wheel does not work. What are the indicators that the wheel on a mouse is not working or is broken?

Usually the wheel on a mouse does not work for a couple of reasons, namely:

• there is no cursor response to mouse movement;
• The scrolling of the ruler occurs jerkily.

In the first case, the cause is a broken axis, and in the second, a problem with the scroll mechanism (it’s enough just to “tighten” it a little). To fix problems with the scrolling mechanism, you will need to do the following:

1. Remove the mouse body.

To do this, unscrew the screws with a screwdriver. They can be under a sticker or under the legs of the mouse.

1. Remove the wheel.

The pin in the scroll mechanism is broken. Carefully remove the wheel from the mouse.

1. Start repairing.

Take an ordinary metal paper clip. Align it, then fold it in half and curl the edges. Next, measure on it the length of the part of the axle mechanism that was broken, and add literally a couple of millimeters to fuse the paperclip inside the wheel. Use pliers to cut off the excess paper clip.

This is how a paperclip should be twisted. Clamp the cut element with pliers and bring it to the fire for maximum heat.

Clamp the resulting structure with pliers.

1. Fuse a paperclip into the wheel.

In the place of the broken axle, quickly insert a red-hot paper clip (before it cools down). Wait for the plastic to harden. Then insert the wheel and axle into place and check the quality of the mechanism.

If the wheel continues to scroll, you need to insert an additional piece of wire (5 mm long) into the contact point between the paperclip and the mechanism.

This is what your repaired wheel should look like.

1. Start assembling the mouse body.

It is assembled in reverse order. Basically, everything is ready.

I hope the problem" Why doesn't the mouse wheel work?» is closed for you today. If you have any questions for me, please ask them in the comments, as well as subscribe to blog updates and don’t miss new episodes. I wish everyone well!

If your mouse wheel suddenly stops working (for example, as a result of a fall or some kind of impact). Without preliminary symptoms in the form of the page jerking up and down when scrolling and at the same time spinning freely, then this article will probably help you.

Mouse wheel scrolls

The mouse wheel is spinning because it's broken! Literally, the plastic axis fell off, through which the torque is transmitted to the rotation sensor, the repair of which is described in another article:. And if the mouse does not work at all, then check if the mouse wire is bent at the base.

Such a breakdown is not a reason to throw away the mouse if you want to tinker for 20-30 minutes (if you go to the store for a new mouse, you will probably spend at least an hour).

I will describe a working and reliable method for repairing a broken mouse wheel. The mouse itself:

Let's disassemble the mouse

Unscrew the screw from below and separate the two parts of the case.

Externally, the mouse looks fine, even the wheel spins in the same way as on a working mouse. Except that it doesn’t spin in steps and with virtually no resistance.

Let's take a closer look at the inside of the mouse:

You will need

• Screwdriver
• Pliers
• Iron paper clip
• Wire cutters
• Fire source (stove, lighter)

Instructions

If part of the wheel axis of your mouse breaks off, the symptoms of such a malfunction are as follows - you turn the wheel, but this is not displayed on the computer screen. To fix such a breakdown, unscrew all the screws on the mouse body. Open your mouse. Remove the wheel and the broken pin. Next, take an iron paper clip. Straighten it out. Then bend in half and twist the ends along the entire length. Measure the length of the broken part of the axle on the resulting structure, adding a couple of millimeters so that you can fuse the paperclip into the wheel. Nibble off the excess with nippers. Pinch the bend of the paper clip with pliers and bring its ends to the fire. Wait until the paperclip is red hot. Now quickly fuse the paperclip into the mouse wheel in the place where the axis was. Once your design has hardened, insert the wheel into place. Spin the wheel to see if the paperclip moves the mechanism inside the mouse. If it does not scroll, insert another small piece of wire about five millimeters long into the place where the mechanism comes into contact with the paperclip. The mechanism should now work. Assemble the housing by screwing it in with screws. The mouse has been repaired.

Another common problem is that the wheel scrolls pages on the screen, but not smoothly, as expected, but jumps up and down. In this case, most likely, your mouse's scroll mechanism has become loose. To fix it, unscrew and open the mouse housing. You will see a wheel inserted into a special mechanism that is responsible for scrolling pages on the screen. Gently pinch the body of this mechanism with pliers. But be careful not to overdo it. If you press it too hard, the wheel may stop spinning altogether, or the scroll mechanism itself may simply break. After you have tightened the mechanism body, turn the wheel. If everything works fine, reassemble the mouse body.

A computer mouse cord is much less durable than the mouse itself. Most often it grinds near the body. Fixing this problem will take much less time than going to the store for a new mouse, which is especially important for piecework wages.

A computer mouse with two buttons and a wheel has long been an almost integral input device for operating systems of the Windows family. Sometimes the operation of this manipulator is disrupted - the wheel spins, the button is pressed, but the system does not show any reaction to this. Let's figure out why this happens and how to fix the problem.

The main problems with the mouse wheel look like this:

• Can't scroll the page in the browser;
• Scrolling throughout the system does not work;
• There is no response to pressing the button;
• Scrolling works, but is jerky;
• Instead of scrolling in the browser, the wheel changes scale.

Malfunctions with the mouse, like other peripheral devices, occur for both hardware and software reasons. Let's look at them in order.

Reason 1: Single failure

The most common cause of problems with the mouse wheel is a random software glitch. If the problem occurs only in the browser, then the problem lies in one of the bugs in the Chrome engine, which currently powers the vast majority of Internet browsers. In this case, the solution would be to open any window (Word or Excel document, long image, any application other than a web viewer) and scroll through several pages - scrolling in the browser should work.

If a failure occurs in all applications, then the easiest way is to restart the PC: clearing the RAM should fix the problem. A simple reconnection of the device to another connector may also work.

Reason 2: Manipulator settings failure

Another common software cause of wheel malfunctions is incorrect mouse settings. First of all, it is recommended to disable or remove third-party mouse configuration software, if installed on your computer.

Removing utilities does not always help solve the problem - you will need to return the default settings using system tools. Access to system mouse parameters and standard values ​​are described in a separate manual at the link below.

Reason 3: Inappropriate drivers

Often, problems with the mouse and its elements occur due to an incorrect or outdated version of the device’s system software. The solution is obvious - the existing drivers need to be removed and suitable ones installed.

1. Launch "Device Manager", the fastest way to do this is through the window "Run": press Win+R, enter the argument devmgmt.msc in the field and click "OK".



2. After downloading the list of equipment, expand the category "Mouse and other pointing devices", where find the position "HID compliant mouse". Right-click on it and select the option "Delete".



3. Confirm the removal, then disconnect the mouse and restart the computer.
   
   
4. Install the appropriate drivers for your pointer and connect it to your PC.

As practice shows, reinstalling drivers can solve the entire range of software problems with the wheel.

Reason 4: Hardware failure

Often problems with the wheel are caused by hardware failure of elements: the rotation sensor, the fastening of the wheel itself, or the control board of the device. As a rule, in this case, almost the entire list of defects mentioned in the introduction is observed. From the point of view of expediency, repairing a mouse is not a very profitable activity, so the best solution in the current situation would be to purchase a new one, especially since they are now inexpensive.

Reason 5: Loaded computer

If scrolling is unstable, and the cursor also moves jerkily, the reason is most likely that the PC or laptop is overloaded. This is also indicated by indirect symptoms such as decreased performance, freezing, or the appearance of “blue screens of death.” You should carry out optimization procedures and unload the processor - this will improve the performance of the computer, which will stabilize the operation of the mouse.



Reason 6: Keyboard problems

If in a web browser and other similar applications the mouse wheel instead of scrolling works as a zoom tool, the reason may not be in the pointing device at all, but in the keyboard: due to hardware or software problems, the key is stuck Ctrl. The most obvious solution would be to replace the faulty element, but temporarily you can get by by software disabling the faulty key or reassigning it to another, little-used one.



Conclusion

We looked at the main problems with the functionality of the mouse wheel on a PC running Windows 7 and provided methods for eliminating them. To summarize, we would like to add that to reduce the risk of hardware failures, it is advisable not to skimp on peripherals and buy devices from trusted manufacturers.

User question

Hello.

Please tell me what to do with a non-working mouse wheel. We reinstalled Windows and now the mouse partially does not work: the arrow runs across the screen, the left and right buttons work, but scrolling through the wheel does not work (you have to drag it with the pointer, which is inconvenient). We tried to connect another mouse to our computer - the same story (our mouse works on another PC) ...

What should I do in this case, why does the mouse not work at all?

PS: we went into the mouse settings in the Windows control panel - but there is no “Wheel” section at all, in which you can set how many lines to scroll the page (although there used to be one!).

Hello!

The problem described above is quite typical, and most likely it is associated with the lack of drivers (probably for some kind of universal serial bus USB port controller, or for the mouse itself (which is less likely, judging by the description)).

In the article I will consider the user’s question and other reasons for this behavior of mice...

By the way, if your mouse does not work at all, I recommend that you read these instructions:

Reasons why the wheel does not work

(the mouse twitches and slows down)

1) Drivers were not installed (or failed)

Perhaps checking the drivers is the first thing you should start with (especially if your problem matches the description of the issue, see above). To do this, open device Manager .

Reference! To open the device manager: press the Win+R button combination, and enter the command devmgmt.msc, click OK. An example is shown in the screenshot below.

The screenshot below shows the “picture” of what usually happens after reinstalling Windows (by the way, in newer Windows operating systems, drivers are installed automatically on many devices). Please note that all devices for which no drivers were found will be located in the "Other devices" , a yellow exclamation mark will appear opposite each one.

There are no drivers for a dozen devices... Device Manager in Windows 7

Next, I recommend opening the tab "Mice and other pointing devices" . It should indicate your mouse; as a rule, it is an HID-compatible mouse. If your tab is empty, or it only contains the “ELAN...” device (touchpad, relevant for laptops), then you simply do not have a driver: either for a mouse (this often happens with gaming mice) or for a USB port controller .

Mice and other devices

How to update drivers:

1. You can install the drivers that came with your computer (usually, they were either downloaded by the seller onto your hard drive or recorded on a separate CD\DVD);
2. Use special utilities to auto-search and update drivers. I have one big article dedicated to this on my blog:
3. Find drivers by VID and PID (special identifiers by which you can find the manufacturer of your equipment, its make, model, etc.) in a search engine, for example, Google. This is a universal method, I will discuss it below. The only negative is that there must be access to the Internet (and without drivers for the network card, it may not exist...).

So, in the device manager you see some device for which there is no driver. Right-click on it and open its properties.

In properties, open the tab "Intelligence", select option "Equipment ID" and copy the first line, which will contain the values ​​VID, PID, REX, SID (etc.).

Next, paste the string into a search engine (for example, Google) and start searching. In my case, for example, dozens of sites were immediately found (and in first place was the laptop manufacturer’s site), where the drivers were downloaded.

After installing them and rebooting the laptop, the mouse was detected and began to work as expected (including the wheel ☺) ...

2) Is the USB port working or is it disabled?

The second thing to pay attention to is whether the USB port works at all. However, in this case, your mouse will not work at all! That is, even the mouse pointer will not move.

First, turn the mouse over and see if the LED on it is lit? If it lights up, it’s not bad, it means there is power and everything is fine with the wire. If it doesn’t light up, try connecting another mouse or flash drive to this USB port. By the way, USB ports may often not work due to a lack of drivers, and not due to physical damage (which I wrote about just above).

By the way, it would also be a good idea to connect the mouse to another computer (laptop) to see if it works on it.

Such simple rearrangements very quickly help determine the culprit...

3) Damage to the mouse (breakage). Physical deterioration

With active use of the mouse (especially in games, various shooting games, where in a fit of passion users often press forcefully and sharply, hitting the buttons), it eventually becomes unusable (nothing lasts forever). As a rule, it all starts with: a double click of the left/right button (although you do a single one), bad scrolling, the cursor starts to twitch “nervously”, etc.

The best diagnosis in this case is to try connecting another mouse to your PC (or this mouse to another PC) and see how it behaves.

In general, in case of physical wear and tear, the best advice is: buy a new mouse (so that it doesn’t cost much). All these repairs, soldering, etc. for an unprepared user - 99% end in wasted time...

4) Incorrect settings in mouse settings in Windows

And the last thing I wanted to focus on: the mouse parameters that are set in the Windows Control Panel. To check the settings: open the section "Equipment and Sound" in Control Panel, then click on the "Mouse" link in the "Devices and Printers" subsection (see screenshot below).

Next, open the “Wheel” section and adjust the number of scrolled lines when the wheel moves (this is set for vertical and horizontal displacement separately). The parameter is individual for each mouse (and it also depends on the user - one is comfortable with turning half the page at once, another needs 1 line...) .

It would also be a good idea to go to the tab and adjust the speed of the pointer. I recommend checking the box next to the item "Enable increased pointer precision" . Thanks to this, your mouse will not twitch as if dumbfounded when you aim at some insignificant detail when you move the pointer slightly.

How to do without a mouse wheel:

1. The keyboard has special keys: PgUp and PgDn. Using them you can quickly scroll the page, convenient even if you have a mouse;
2. Key "Space"- if you press the key, the page will scroll down. To scroll up - press Shift+Space;
3. You can also use your mouse pointer to drag the slider up or down (not very convenient, but it also works).

This is where I end this article. All the best!

For additions - a separate merci...

If your mouse wheel suddenly stops working (for example, as a result of a fall or some kind of impact). Without preliminary symptoms in the form of the page jerking up and down when scrolling and at the same time spinning freely, then this article will probably help you.

Mouse wheel scrolls

The mouse wheel is spinning because it's broken! Literally, the plastic axis fell off, through which the torque is transmitted to the rotation sensor, the repair of which is described in another article:. And if the mouse does not work at all, then check if the mouse wire is bent at the base.

Such a breakdown is not a reason to throw away the mouse if you want to tinker for 20-30 minutes (if you go to the store for a new mouse, you will probably spend at least an hour).

By default, the double-click speed slider should be in the center, and the sticky mouse buttons option should be disabled. Try setting these parameters and check if the problem is resolved. If not, another radical software way to “cure” a double click is to remove the mouse driver. How to properly remove the driver is written.

conclusions

Mice are one of the most actively used computer devices. Therefore, it is not surprising that they often fail. However, due to the simplicity of their design, in most cases anyone can fix a mouse!

To do this, you don’t need to know how to solder or understand electronics. The main thing is to clearly diagnose the cause of the breakdown. Here, as in medicine, a correct diagnosis is the path to successful repair.

I hope our article will allow you to determine what exactly is broken in your mouse, and therefore, to fix the problem. Good luck with your renovation!

User question

Hello. Please tell me what to do with a non-working mouse wheel. We reinstalled Windows and now the mouse partially does not work: the arrow runs across the screen, the left and right buttons work, but scrolling through the wheel does not work (you have to drag it with the pointer, which is inconvenient). We tried to connect another mouse to our computer - the same story (our mouse works on another PC) ...

What should I do in this case, why does the mouse not work at all?

PS: we went into the mouse settings in the Windows control panel - but there is no “Wheel” section at all, in which you can set how many lines to scroll the page (although there used to be one!).

Hello!

The problem described above is quite typical, and most likely it is associated with the lack of drivers (probably for some kind of universal serial bus USB port controller, or for the mouse itself (which is less likely, judging by the description)).

In the article I will consider the user’s question and other reasons for this behavior of mice...

By the way, if your mouse doesn’t work at all, I recommend reading these instructions:

Reasons why the wheel does not work

(the mouse twitches and slows down)

1) Drivers were not installed (or failed)

Perhaps checking the drivers is the first thing you should start with (especially if your problem matches the description of the issue, see above). To do this, open device Manager .

Reference! To open the device manager: press the Win+R button combination, and enter the command devmgmt.msc, click OK. An example is shown in the screenshot below.

The screenshot below shows the “picture” of what usually happens after reinstalling Windows (by the way, in newer Windows operating systems, drivers are installed automatically on many devices). Please note that all devices for which no drivers were found will be located in the “Other Devices” tab, and a yellow exclamation mark will appear next to each one.

There are no drivers for a dozen devices... Device Manager in Windows 7

Next, I recommend opening the “Mice and other pointing devices” tab. It should indicate your mouse; as a rule, it is an HID-compatible mouse. If your tab is empty, or it only contains the “ELAN...” device (touchpad, relevant for laptops), then you simply do not have a driver: either for a mouse (this often happens with gaming mice) or for a USB port controller .

How to update drivers:

1. You can install the drivers that came with your computer (usually, they were either downloaded by the seller onto your hard drive or recorded on a separate CD\DVD);
2. Use special utilities to auto-search and update drivers. I have one big article dedicated to this on my blog:
3. Find drivers by VID and PID (special identifiers by which you can find the manufacturer of your equipment, its make, model, etc.) in a search engine, for example, Google. This is a universal method, I will consider it below. The only negative is that there must be access to the Internet (and without drivers for the network card, it may not exist...).

And so, in the device manager you see some device for which there is no driver. Right-click on it and open its properties.

In properties, open the tab "Intelligence", select option "Equipment ID" and copy the first line, which will contain the values ​​VID, PID, REX, SID (etc.).

Problems with the mouse caused by glitches in programs can be resolved independently. Hardware failures, including those related to the mouse wheel, should be fixed by yourself only in cases where you are technically savvy and are not afraid of losing the warranty on the gadget.

They do everything possible to simplify the interaction between the software and the user. Although currently the unspoken standard setter in this area, Microsoft, has relied on touchscreen technologies, as can be seen from the new version of the system, it is quite difficult to work with programs in Windows without a mouse. If the mouse wheel does not work, then many users begin to panic. Being an electronic device, the mouse can indeed fail, but before you go to the store for a replacement, it would be a good idea to try to more thoroughly check its performance.

Since its inception, the mouse-type manipulator has undergone a number of changes, affecting, first of all, the principle of reading movement data: a heavy ball covered with a layer of rubber and rollers, constantly clogged with debris, were replaced by an optical system. But the wheel and buttons have undergone less dramatic changes: holes are located on the inside of the disk at a certain distance from each other. On one side of the disk there is a light-recording sensor, and on the other there is an infrared diode, a classic optocoupler pair. When the user rotates the mouse wheel, the light from the diode is periodically interrupted. Such a system allows electronic circuits to count pulses and determine the direction of rotation and speed.

If the mouse wheel does not work, this, as indicated, is not a reason for an exchange. First you need to check which programs are experiencing problems and try to replace them. Sometimes the problem lies in incorrect program settings.

The next step is to make adjustments to Windows settings. Click the “Start” button, open the “Control Panel” and go to the “Mouse” tab. Here you can make changes to the operation of the wheel.

If everything is so simple, then why are the forums full of questions like “the mouse wheel doesn’t work”? The answer is simple: much more often the problem lies in the hardware. Sometimes the mouse wheel does not work due to a malfunction of the optocoupler pair. Fortunately, some repairs can be done yourself at home.

From the computer, take a screwdriver from the watch kit and unscrew the two screws (usually) on the underside of the mouse. The screws may be hidden under stickers, so carefully probe the hidden surface. Then carefully open the case.

The optocoupler pair is easy to find - it is next to the wheel. Using a piece of dry cotton wool, remove all dirt from the window-holes on the wheel rim, and also carefully wipe the LED and sensor. Often you can see entire strands of hair blocking the light. In rare cases, it is necessary to align the level of the diode and sensor (if they are bent, this is immediately noticeable).

Sometimes the situation when the mouse wheel does not work is due to its rubber coating. Over time, the rubber becomes a little larger in diameter and does not fit too tightly onto the plastic base of the wheel. When trying to rotate the wheel, the user actually rotates only the rubber ring, while the internal mechanism itself remains at rest. What’s interesting is that it’s not always possible to determine such a malfunction without disassembling the case. Owners of A4Tech products who are looking for an answer to the question of why the wheel does not work are well familiar with it. The solution is quite simple: the seat of the base disk and the inside of the rubber ring are thoroughly wiped of grease and dust using cotton wool and alcohol. Then the ring is fixed in the simplest and most effective way - with superglue. Two or three points around the perimeter are enough.

If this does not help, then, alas, you have a direct route to the workshop or to the store for. With any decision, you must remember that you should not ignore installing the driver on the device.
