What s wrong with the wheel in the middle of my mouse not working?

If the mouse hardware is not broken, then the problem may appear in the driver, this kind of problem is rare, generally appears on the U port mouse.

Personally, I suspect that it is a problem with the hardware of the mouse, but you can take it apart and take a look, the internal structure is very simple.

If it's a driver error, I'm not sure where it is. Think that in the motherboard driver, you can reinstall the motherboard driver.

Deleted the program you installed.

Then reboot and try again.

If it's the program you installed that caused you to have this situation (if you don't need it in particular), you can't. It may be due to some of the program's default settings. After making some settings for the program, restart the machine and try the different settings a few more times.

Probably just fine.

Don't think about it.

If it was easy to use before, it will not work well after the system.

It's definitely a drive issue.

Of course, it is also possible that some of the system's settings are disabled.

The driver is most likely to be reinstalled It is recommended to reinstall the driver.

You find a driver to equip it.

It is better to match the drive...

Just uninstall the drivers you installed and you're good to go.

Either you will use it, you won't need a scroll wheel, or you can disassemble the mouse to see if the axis of the scroll wheel is aging, and find a way to get it, or you can spend some money, and it won't cost much money, and you can buy a new one.

Take the Mi Mouse as an example:

1. It may be that the mouse interface is in poor contact, because the mouse is an external device, the poor interface contact is most likely to lead to the failure of the mouse, in such a situation, you can fix the interface of the mouse, if the mouse is out of the computer interface, you can turn off the computer first, insert the mouse, and then turn on the use.

2. It may be that there is too much dust inside the mouse, the mouse has been used for a long time, and the accumulated dust will be concentrated inside the mouse, you can remove the ring under the mouse, and then take out the ball, and then use a toothpick to pick out the ash gathered on the roller in the mouse (the general mouse has three rollers), and finally put the mouse ball in, and the ring can be screwed on the mouse.

3. It may be that you accidentally deleted the driver of the mouse, and you can reinstall the driver of the mouse once.

This answer applies to most brands and models of mice such as Xiaomi, Huawei, etc.

In the process of work, the mouse suddenly fails, and there is no time to solve it for the time being, at this time, you can use the keyboard shortcut keys to continue the operation, several effective shortcuts are: arrow keys to move, enter key (enter) for mouse double-click, esc key for cancel, shift+f10 for right-click mouse click, win+e to open explorer.

Click [Pulley] in the mouse properties, set both vertical scrolling and horizontal scrolling to 3, and finally click OK, and your mouse wheel can move. If the mouse still doesn't respond, it means that the mouse is faulty and needs to be replaced.

There may be some netizens who don't know much about the failure of the middle mouse pulley, so I will introduce you to the causes and solutions of the failure of the middle mouse pulley, I hope it can help you!

Solution 1 for the failure of the middle wheel of the mouse:

1. Use the registry solution, first enter the registry, method, at the beginning of the desktop, open the start menu, and then open the "Run" program, or you can directly use win + r to open the "Run" program, enter the regedit command in the box, and press "OK".

2. After entering the registry, first select the root key key of "hkey current user", then open its subkey, and find the "Control Panel" item in the subkey.

3. Then open the sub-item of "Control Panel" and find the item "Dosktop".

4. Then move the focus to the right window of "dosktop", drag the scroll bar, and find the "wheelscrolllines" item.

5. Then right-click on "wheelscrolllines", open the right-click menu, and select the "Modify" command.

6. A string window pops up, and under "Data Value", there is a box, which is often easy to be changed by viruses or system errors.

7. Modify the value of the data value to "3", and then press "OK" to save and exit the window. Exit the registry again.

8. Come to the desktop, open the start menu, click "Shut down the computer", in the shutdown interface, select the "Restart" button, after the computer restarts, the problem of the mouse wheel can be solved.

I believe that the problem of the mouse wheel can not be used normally can be easily solved for the registry-related modifications, of course, this method is only effective for the system problems that cause the mouse to not be used normally, if it is a virus or the mouse itself, then it is recommended to kill the system or replace the mouse to try.

Solution 2 for the failure of the middle wheel of the mouse

Open Device Manager.

Under "Mouse and other pointing devices", find "PS 2 compliant mouse", then press the right mouse button and select "Uninstall".

At this time, the system will prompt you to restart, click "OK" according to the prompts, and the system will restart.

When the system boots up, it will also prompt a reboot due to the installation of new hardware, please click "OK" again according to the prompts to let the system restart. At this point, the newly installed PS 2 mouse wheel will work fine.

The mouse wheel rolls out of order, and most of them are the coordinate encoders next to the pulley.

If it is caused by dust, oil or oxides, simply remove the housing, remove the circuit board and pulley, and use soft paper and eraser to test the metal position in the fixed and rolling contacts.

How to fix the failure of the mouse wheel to scroll up and down

Prepare tools: scroll wheel malfunctioning mouse, eraser, small blade, small tweezers.

Phillips screwdriver.

Flat-neck screwdriver, soft paper.

1. Use a Phillips screwdriver to remove the mouse screws, and then use a flat-top screwdriver to pry the mouse open.

2. After prying open the mouse, take out the internal circuit board, it should be noted that some mouse circuit boards also have screws, and you need to remove the screws to take out the circuit board.

3. After taking down the circuit board, take down the roller, and then repair the coordinate encoder next to the roller. Use a small blade to pry the four tentacles of the coordinate encoder apart, remove the tabs, and then remove the rolling contacts.

4. Wipe the metal position of the fixed contact and the rolling contact with soft paper, wipe off the dust and oil, and then wipe the metal part of the fixed contact and the rolling contact with the corner of the eraser, wipe off the oxide, and finally put it back and cover the shell.
