Why is the mouse wheel not working on a computer mouse? Mouse scroll wheel repair. Why is the scroll wheel on the mouse not working?

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 is spinning, the button is pressed, but the system does not show any reaction to this. Let's see why this happens and how to fix the problem.

The main problems with the mouse wheel look like this:

Unable to scroll the page in the browser;
Scrolling across the entire system does not work;
No response to button press
Scrolling works, but jerkily;
Instead of scrolling in the browser, the wheel zooms.

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

Reason 1: Single failure

The most common cause of mouse wheel problems is an accidental software glitch. If the problem is observed only in the browser, then the snag lies in one of the bugs in the Chrome engine, which now runs the vast majority of Internet browsers. In this case, the solution is to open any window (Word or Excel document, a long picture, any application other than a web viewer) and scroll a few pages - browser scrolling should work.

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

Reason 2: Manipulator settings failure

Another common software cause of wheel failures is incorrect mouse settings. First of all, it is recommended to disable or remove third-party mouse configuration softwareif one is installed on the computer.

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

Reason 3: Unsuitable drivers

Often, problems with the mouse and its elements appear due to an incorrect or outdated version of the device's system software.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 the appropriate ones installed.

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

Reason 4: Hardware failure

Often, problems with the wheel are caused by hardware failure of the 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 occupation, so the best solution in this situation would be to purchase a new one, especially since they are now inexpensive.

Reason 5: Busy computer

If the scrolling is unstable, and the cursor also moves in jerks, the reason is most likely a busy PC or laptop. This is also signaled by indirect symptoms such as a decrease in performance, freezes or the appearance of "blue screens of death". It is necessary to carry out optimization procedures and unload the processor - this will improve the performance of the computer, which will also stabilize the operation of the mouse.

Reason 6: Keyboard issues

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 manipulator at all, but in the keyboard: due to hardware or software problems, the key is stuck ctrl. The most obvious way out would be to replace the faulty element, but temporarily you can get by with software disabling the failed key or reassigning it to another, little-used one.

Conclusion

We looked at the main problems with the performance of the mouse wheel on a PC running Windows 7 and provided methods to resolve them. Summing up, we want to add that in order to reduce the risk of hardware breakdowns, it is advisable not to save on peripherals and buy devices from trusted manufacturers.

Users don't realize how important a mouse wheel is until it falls into disrepair. Meanwhile, it is the wheel that is responsible for scrolling pages, zooming in editors and browsers, opening a page in a new tab, and also for some of the game functions. What to do if the wheel does not work? Do not rush to change the mouse - try troubleshooting.

How to fix a mouse wheel

The key causes of wheel problems are incorrect software or mechanical damage to the mouse. Having found a failure, first of all connect the accessory to another computer and check if it works. If the scrolling works, the reason is in the settings, and if not, in the Solutions differ for each specific case.

If pressing and scrolling up and down does not work

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

Remove the protective pads at the bottom of the mouse and unscrew the bolts.
Detach the bottom panel. You will see the board and below it is the scrolling mechanism.
Raise the board by first unscrewing the bolts.
Remove 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 with a paperclip:

Straighten the paper clip, bend the wire in half and twist into a bundle.
Attach the part to the wheel, in the place where the axle was located, and cut it to size with wire cutters, adding 1–2 mm.
Heat the desired part of the wire red-hot on a gas stove or with a piezo lighter and attach it to the break in the axis.
Once the material has melted, reassemble the wheel and test the scrolling and pressing.

Step 1 Remove the mouse base Step 2 Remove the wheel Step 3 Replace the wheel axle Sometimes it's not the axle itself that breaks, but the tabs that hold it

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

Sometimes the axle does not break off, but falls out. Having found the dropped pin, replace it with an axle of a larger diameter.

Pages not scrolling

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

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

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

Open "Device Manager".
Look for Mice and pointing devices.
Select the mouse you are using and double click on its name.
Open Driver and click Update.

If the update does not work, 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 scrolls jerkily and “jumps” up and down, the touch sensor is faulty. To fix it:

Disassemble the mouse following the instructions above.
Remove the protective cover from the scroll mechanism.
The sensor is pressed against the wheel by four metal petals - gently bend them one by one.
Bend back 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.
Lay the clamping part on the table and press on the middle with a screwdriver so that a dent remains. It will ensure that the part works correctly when scrolling.
Replace the mechanism, bend the protection and firmly press the petals back.
Assemble the wheel, reinstall the board and the bottom of the case. Fix the parts with bolts.

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

The wheel does not turn and rattles

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

Disassemble the mouse and remove the wheel.
Break off the petals holding the protection.
From copper wire, make 4 brackets of a suitable size.
Solder the brackets in place of the petals and assemble the mouse.

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

Wheel clicks not working

If the mouse wheel scrolls through the pages, but the system does not respond to clicks, listen for clicks when you click. If there is, check the program settings:

Download the hotkey remapping app - Antsoft Key Manager or Oscar.
Find out which function is assigned to click the wheel.

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

If you don't hear a click, it's a hardware failure. Disassemble and repair the mouse or replace with a new one.

Conflict between Windows 10 and mouse drivers - how to fix

In Windows 10, scrolling works in Explorer, browsers, editors and the standard environment, but in the Start menu and some preinstalled 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.

In the Windows 10 Start menu, if you select the All Apps section, you can access all installed programs, including standard ones. By scrolling the mouse wheel, the user can select the desired software and run it. However, after another small update to Windows 10, users began to complain about the “non-working” mouse wheel. In fact, it is physically correct. However, with a system update, changes were made that affected the functionality of the mouse scroll wheel. This problem can be corrected by editing the settings.

Customizing the mouse scroll wheel in Windows 10

In the Windows 10 operating system, all inactive application windows in the Start menu are not scrolled using the scroll wheel. To correct this situation, perform the following steps:

Click "Start", "Settings". A new window will open. Here we select the "Devices" section.

In the menu on the left, select the "Mouse and Touchpad" section. In the "Scroll inactive windows when you hover over them" item, drag the slider to the "On" position.

We save the changes.

Scrolling with the mouse wheel will now work when viewing Start menu items.

You will need

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

Instruction

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

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

How to fix a broken or badly working wheel on any mouse.

A computer mouse is a manipulator or pointing input device with which PC users can easily control the cursor on the screen. No matter how simple this device may seem at first glance, it is not so easy to disassemble it. Consider several options for parsing the mouse.

You will need

Screwdriver

Instruction

If you can't find any screws or latches, look under the rubberized stickers (the mouse slides on them while moving). Unfortunately, they will have to be torn off - after all, it is under them that the screws are hidden, by unscrewing which, you can disassemble the mouse.

When there is a break in the wire of a computer mouse, then it, accordingly, stops working. This happens, as a rule, very rarely: usually mice with such a problem do not celebrate their first anniversary.

You will need

Stationery knife, screwdriver "+", electric soldering iron, solder, rosin.

Instruction

Comparing the breakdowns of the mouse, an interesting conclusion can be drawn - part of the malfunctions of this device lies in the kink of the wire, when in the mouse. Therefore, if you had such a misfortune as a mouse breakdown, and in the computer room they were convinced that it had a reliable manufacturer, you can be sure that, most likely, there was a wire break.

Take the mouse in your hand and turn it over. Loosen all connecting screws. Remove the top case.

Remember the location of the wires by color. It is best to photograph or sketch on paper.

Turn on the soldering iron to heat it up. It is worth noting that for soldering it is worth using a soldering iron with a power of up to 40W, preferably 25W. Before using a soldering iron, it is necessary to clean the tip and dip it in rosin.

Carefully unsolder the wires with a heated soldering iron. Set the soldering iron aside.

Cut off the damaged part of the mouse wire with a sharp clerical knife. It is worth cutting off no more than 3 centimeters. Strip all contacts and dip in rosin.

Solder the wires to the mouse pins. Then assemble the body.

note

If you have a mouse from Microsoft and there were no connecting screws on the back of the mouse, then this mouse does not need to be disassembled. This type of computer mouse comes with a glued body, their release is the idea of Microsoft. According to the general agreement, they change the mouse if you write to them at their email address, indicating the serial number of the mouse. This trick is used in many computer shops. Therefore, it may turn out that your new mouse has already been received.

If you have problems with the mouse used in personal computers, do not rush to throw it away. Repairing a wired "mouse" for a computer is usually not difficult. The main thing is to properly disassemble and assemble the device so that there are no unnecessary parts left.

You will need

Napkin, knife, scissors, Phillips screwdriver, electrical tape or tape

Instruction

Before disassembling, turn off the "mouse", wipe it from the outside with a napkin. Unscrew and remove the top cover. After unscrewing the screws, slide the cover back and up slightly. There is no need to apply force, the operation should be easy.

If you find it in the cable, fix it. Isolate the wires. Insert the wire back into the mouse latch. Make sure that the wire does not interfere with moving parts (wheel and buttons). The wire should also not fall into the grooves and on the edge of the housing.

Insert the front part of the cover into the grooves and connect the cover to the bottom. Fasten the cover with the screw(s). Before tightening the screws, turn them counterclockwise twice - this will help to get into the thread.

When you attach a mouse to it, load the car and check the operation of the manipulator. The matter is simplified if the "mouse" is connected via USB, you do not need to turn off the computer. Congratulations, you just managed to disassemble and, importantly, correctly assemble the “mouse” on your own.

How to fix a mouse if the button works many times in one

It happens that an optical mouse randomly loses and restores its performance when the cable is wiggled at the point of entry into the case. This is where the mouse cord most often frays with heavy use. In order to repair the manipulator, it is important to disassemble it correctly.

Instruction

Disconnect the mouse from the computer. Locate the screws at the bottom and remove them. Try to open the body of the manipulator by prying the top cover from the side opposite to the cable entry side.

If you can’t open the mouse, then you have to find the place where the hidden screws are located. They are usually located under rubber feet or stickers. Please note that in the second case, removing or piercing the sticker deprives you of the right to warranty repair of the mouse. Be sure to save the rubber feet, as the manipulator is inconvenient without them.

After opening the mouse, carefully pull out the wheel. Usually it is equipped with a shaft, one end of which is mounted in a detachable hinge, and the other end is inserted into the encoder hole. Once the shaft is free, lift it slightly off the hinge and then gently pull the opposite end out of the encoder.

Remove all screws securing the board, then release it from the latches and remove. Separate the plastic optical overlay with the lens and prism from the board (they are made as a single unit).

Leave the multi-pin on the end of the cable plugged into the mouse board. Cut the cord with wire cutters before entering the housing. Strip the cable conductors. Based on the colors of the conductors included in the board from the side of the multi-pin connector, solder the cord conductors that have the same colors to the pads located on the reverse side of the board in the place where the multi-pin connector is soldered.

Without assembling the mouse, connect it to the computer, then check if the LED lights up, and if there is a reaction to the rotation of the wheel, pressing the keys. Putting an optical overlay on the board, you can check the response to movement. If a USB key is being repaired, it can be connected simultaneously with another mouse, which can have both USB and PS / 2 interfaces. Please note that a PS / 2 interface key cannot be connected when it is already loaded - it may not be detected until a reboot. After making sure everything is , turn off the mouse again.

Route the cable in such a way that it does not interfere with the closing of the case, pressing all the keys and rotating the wheel. Assemble the manipulator in reverse order. Don't forget to reinstall even small parts such as the optical bezel or rubber feet.

Connect the mouse to the computer and make sure it works.

manipulator disassemble

The cord of a computer mouse is much less durable than the manipulator itself. Most often it is frayed next to the body. The work to fix this problem will take much less time than going to the store for a new mouse, which is especially important with piecework wages.

Instruction

Disconnect the mouse from the computer. If it has a USB or COM interface, it does not even need to turn off the machine. Before disconnecting the PS/2 pointing device, turn off the computer after correctly shutting down the operating system on it.

Locate the screw on the mouse body, located on the bottom in the corner opposite the cable entry. It may be located under the sticker - in this case, remember that damage to it will void the warranty. If this suits you, or the warranty is over anyway, pierce or remove the sticker. Remove this screw, attach it to the magnet, and then open the manipulator.

Remove the wheel carefully so as not to break its axle. If you miscalculate the force a little - and it will break off from it and remain in the rotating switch.

Locate the screws that secure the board to the bottom of the manipulator. Unscrew them and remove the board. Attach the screws to the magnet. Be careful not to lose the molded light guide-lens combo.

Cut the mouse cord before entering the case. Remove the individual conductors from under the sheath.

Strip and tin conductors. Find on the back of the board the pins of the connector to which the old cord is connected. Solder the conductors to its terminals directly from the back, guided by the colors of the conductors included in this connector.

After soldering is complete, cut the rest of the old cord from the board.

Reinstall the board and wheel. Don't forget to position the light guide in the same way as it was before. Lay the cord in such a way that it does not interfere with the operation of any mouse mechanisms (board, wheel).

Close the mouse case. Connect it to a computer (turned off if it has a PS/2 interface). Check if it worked. If not, then the break is located elsewhere in the cable, or the cause of the malfunction is not in it at all.

how to fix a mouse

Most often, the mouse loses its performance due to chafing of the cable at the entrance to the case. The rest of its parts can be completely serviceable. Such a breakdown can be eliminated if the mouse case is properly disassembled. How to do this, read on.

Instruction

Disconnect the mouse from the system unit. Look at its bottom. Find screws. Take the appropriate screwdriver and unscrew them. Open the case. Please note that this must be done by prying off its upper part from the side opposite to the cable entry. If you cannot disassemble the laser mouse, then you have not removed all the screws.

Check for hidden screws. They can be located under the stickers and rubber feet on the bottom of the mouse body. Also note that if the mouse is still subject to warranty repair, then violation of the stickers and rubber inserts deprives you of the right to use it if necessary.

If the screws are under the rubber feet, unscrew them and set the feet aside in a visible place so that they are not lost, because later, using a mouse without rubber feet will be inconvenient.

Open the mouse. Remove the wheel. The wheel is usually equipped with a shaft. One end of the shaft is mounted in a detachable hinge, the other end is inserted into the encoder hole. Release the shaft, lift it slightly, and then remove it from the encoder to disassemble the optical mouse.

Take a screwdriver. Remove all screws that secure the board. Then open all the latches and remove the board from its place. Remove the optical overlay with the prism and lens from the board. Leave a multi-pin connector at the end of the cable. Take the cutters. Cut the cable before it enters the housing.

Clean up all contacts. Take a soldering iron. Based on the colors, solder all the conductors to the corresponding places of their entry into the board on the same contact pads. Do not assemble a laser mouse. Connect it to your personal computer. Check if the LED. Then check if there is a reaction to the rotation of the wheel and pressing the keys.

Put the optical overlay on the board and check the movement. If the mouse is connected to a USB port, it will be detected even when the computer is already on, which cannot be said about a mouse with a PS / 2 port. It won't show up until the PC restarts. If the mouse is working properly, route the cable so that it does not interfere with closing the case. Assemble the mouse, screw in all the screws, reinstall the rubber feet.

If you encounter any problems with the operation of the "mouse" type manipulator, which is called in everyday life - the mouse, do not rush to say goodbye to it. Repairing an ordinary wired mouse is quite simple, even for a non-professional technician. The most important thing here is to disassemble and assemble this device and not find “extra” parts after assembling.

Instruction

Prepare the necessary tools for the job. You will need a paper napkin, a knife, a small screwdriver and electrical tape. In most cases, the reason for the malfunction of the manipulator is a break inside the cable that connects to the mouse. But it can also be in the pollution of the wheel or clogging of the mouse, which often happens with old "ball" manipulators.

Disable mouse from the power supply and wipe with a tissue before starting disassembly. Unscrew the bolts from the bottom of the mouse with a screwdriver and carefully remove the cover (in order to remove it, slide it slightly back and up). You should not press - manipulations should be carried out with ease, otherwise you can damage the grooves, and the mouse will not assemble properly.

Troubleshoot. If it is found in the cable, repair it and insulate the wires with electrical tape. Insert the wire into the retainer and make sure that it does not interfere with the operation of the moving parts of the manipulator (buttons and wheel). Make sure that the wire does not get caught in the grooves and on the edges of the case, otherwise this may cause a malfunction or slow operation.

Insert the removed upper part of the manipulator cover back into the grooves and connect it to the bottom with hand pressure. Screw the bolts into place. Before tightening them, turn the bolts counterclockwise a couple of times, which will help to accurately hit the threads.

Connect the manipulator to the turned off computer, boot the computer and check the operation of the mouse. However, if the mouse is powered by USB, you do not need to power off the computer. If the manipulator worked properly, then everything worked out, and you did an excellent job with the problem. Thus, you can periodically disassemble the manipulator to clean it from dust and to prevent breakdowns.

Sometimes the computer mouse abruptly loses its working capacity. This is due to the chafing of the cable at the case itself. In such a situation, you have two options: buy a new mouse or try to fix the old one.

Instruction

Disconnect the mouse from the personal computer. Take a small Phillips screwdriver to disassemble the computer mouse. Locate the mounting screws on its bottom surface. Unscrew them with a screwdriver.

Then try to remove the top cover of the case. Pry it with a thin sharp object from the side opposite the cable entrance to the mouse. If the case does not lend itself, then there are hidden screws. As a rule, they are located under the rubber feet of the mouse. Remove the rubber bands from the holes. Use a Phillips screwdriver to remove the remaining screws.

Look under the stickers. Mounting screws may also be hidden there. Please note that the sticker is only possible if the warranty period has expired. Otherwise, it will not be possible to repair your computer mouse in the service center.

Perhaps one of the most common breakdowns is problems with the scroll wheel. As I already noted, such breakdowns are of two types:

1. The wheel does not work completely ( I consider this case in the article).
2. The wheel works, but jerkily.

Here I consider the second option, when the pages on the screen scroll up and down in jerks, and not smoothly, as expected. This indicates that the mouse scroll mechanism is loose. By the way, this problem is a characteristic feature of A4Tech X7 mice. It occurs in almost any model of this series after six months of active use. However, sometimes this behavior is due to the settings of the mouse or a particular program. For example, it is because of this that it may not work.

There are three ways to repair a loose scroll mechanism:

I. Lubrication of the scroll mechanism

This is a way for those whose scrolling mechanism has not yet completely worn out, as well as for preventing problems with scrolling in new mice.I strongly recommend that you start the repair with this method!

1. Disassemble the mouse

To begin with, if your mouse wheel does not work (it moves jerkily), you need to disassemble its case. One screw is usually visible, another is hidden under a sticker. In some models, a couple more screws may be under the legs. Pay attention to how the mouse cord was located in the case.

2. Clean the sensor

Having disassembled the case, you will immediately notice the wheel inserted into a special mechanism. It is he who is responsible for scrolling pages on the screen. You need to drop 2-3 drops of alcohol on it, then scroll the wheel and blow it out with your mouth. The operation must be repeated several times.

3. Lubricate

For lubrication, you need high-quality liquid oil. It should not be liquid, like water, but thick enough to drip. You can also use silicone lubricant, for example in aerosol cans, which are available at any auto shop.

Silicone lubricant in aerosol cans.

It is necessary to drop 1-2 drops inside the scroll mechanism, then scroll the wheel to better distribute the lubricant. We remove excess if oil flows out.

II. Fixing with metal staples

This method should be used if the scroll mechanism is already loose and lubrication no longer helps. Wayeffective in cases wheremouse wheel not working , however somewhat time consuming and requires soldering iron skills.

1. Again, disassemble the mouse (see previous paragraphs)

2. Install the brackets

Now you need to make metal brackets with which to fix the scroll mechanism.

There are two options here:

a) No soldering. You can make two U-shaped brackets from metal plates (for example, from automotive wiring terminals). Such staples will be fastened by crimping with pliers without the use of soldering.This method is preferable, since the staples attached by soldering may fall off during subsequent parsing. I think there is nothing complicated in this method. For a better understanding, look at the photo:

Don't forget to lubricate the scroll at the end of work (see item i).

b) With soldering. Also, staples can be made of copper wire with a thickness of about 1 mm. Other metals will not work, because due to their high elasticity it is difficult to tighten them, and besides, they are difficult to solder.

Staples are made in the form of an equal-angle corner. A piece of wire is fixed in a vise and then carefully bent at a right angle. You can bend it with pliers or gently tapping a hammer. The ends of the staples are slightly filed to give them a flat shape.

The final stage: pre-prepared staples are soldered at one end to the metal side of the scroll. Instead of long explanations, I propose to carefully consider this photo:

The soldered corners can be pressed a little more with pliers, but this must be done very carefully and only if the quality of the soldering allows. The interfering ends of the staples (if any) are ground with a file.

At the end of the work, it does not hurt to lubricate the scroll mechanism (see point I). This will avoid oxidation and increase the life of the scroll.

III. Preload encoder ("wheel sensor")

This method is also used for thoroughly shaky scrolling mechanisms. It is much simpler and less time consuming than the previous method, but less effective. Repaired in this way, the scroll will again start to act up in a month and a half or two months, and the next repairs will be enough for an even shorter period.

1. Disassemble the mouse (see previous paragraphs)

2. Press the encoder ("wheel sensor")

Having disassembled the case, you will immediately notice the wheel inserted into a special mechanism. It is he who is responsible for scrolling pages on the screen. Now, with the help of pliers, you need to slightly tighten this mechanism. This must be done very carefully. Remember: you can always tighten a little more, but you can’t restore an already broken scrolling mechanism.

This is what the scroll mechanism looks like. The arrows indicate the places that need to be tightened.

In the hole where the pin of the wheel is inserted, you can make a thin gasket (duct tape is ideal for this). Now it will fit snugly against the scroll mechanism.

3. We check the performance

At the end, you need to check how the wheel spins. If necessary, you can tighten a little more. Then the mouse body is assembled.

Now you know what to do ifmouse wheel does not work (moves in jerks) . And if you are interested in what to do if the mouse double-clicks, then you can read about it in the article.

Thanks

In writing this article, I used several instructions, the creators of which I would like to thank. Namely: FenixSU for the method of fixing the scroll with metal brackets; Steve_Key for the way the scroll is lubricated, as well as the user xatab25, thanks to which I significantly expanded this article.
