Developers of modern operating systemsthey do everything possible to simplify the interaction of the software GUI and the user. Although currently the unwritten legislator of standards in this area, Microsoft has relied on touchscreen touchscreen technologies, as can be seen from the new version of the system, it is rather difficult to work with programs in Windows without a mouse. If the mouse wheel does not work, then many users start to panic. Being an electronic device, the mouse can really fail, but before going to the store for a replacement, it is worth it to try to check its operation more carefully.
Манипулятор типа «мышь» с момента своего The appearance 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: there are holes at a certain distance from each other on the inside of the disk. On one side of the disk, a dimming sensor is mounted, and on the other, an infrared diode, a classic optocoupler pair. When the user rotates the mouse wheel, the diode light intermittently interrupts. 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 is howindicated no reason for exchange. First you need to check which programs are failing, try to replace them. Sometimes the problem is wrong program settings.
The next step is to make adjustments to the Windows settings. Click the "Start" button, open the "Control Panel" and follow the "Mouse" tab. Here you can make changes to the wheel.
If everything is so simple, then why forums are fullquestions like "mouse wheel doesn't work"? The answer is simple: much more often the problem lies in the hardware. Sometimes the wheel does not work with the mouse due to a malfunction of the optocoupler pair. Fortunately, some types of repair can be performed independently at home.
Отключаем мышку от компьютера, берем отвертку из clock set and unscrew the two screws (usually) from the bottom of the mouse. Screws can be hidden under the stickers, so carefully we probe the hidden surface. Then gently open the case.
Optocoupler pair is easy to find - it is next towheel. With a piece of dry cotton wool, we remove all the dirt from the window-holes on the wheel disk, and also wipe the LED and the sensor thoroughly. Often there can be seen whole hanks of hair blocking a beam of light. In rare cases, it is necessary to level the level of the diode and the sensor (if they are curved, then it is immediately noticeable).
Sometimes a situation where the mouse wheel is not working,tied to its rubber coating. Over time, the rubber becomes slightly larger in diameter and is not too tightly fixed on the plastic base of the wheel. Trying to rotate the wheel, the user, in fact, rotates only a rubber ring, and the internal mechanism itself remains at rest. What is interesting: it is not always possible to determine such a failure without disassembling the case. Owners of A4Tech products are well acquainted with it, looking for an answer to the question of why the mouse wheel x7 does not work. This is solved quite simply: the seat of the base disk and the inside of the rubber ring are thoroughly wiped off of grease and dust with cotton and alcohol. Then the ring is fixed in the simplest and most effective way - superglue. Two or three points along the perimeter are enough.
If this does not help, then, alas, a direct path to your workshop or store for a new mouse. With any solution you need to remember that you do not need to ignore the installation of the driver on the device.
