It is impossible to imagine a modern computer without a mouse. One of the main reasons for this is the popularity of graphical software interfaces. This trend was laid back in the days of DOS, when Volcov and Norton Commander shells, as well as Dos Navigator, appeared.
Further, the relay passed to the operating systems Windows, Linux, and the Mac did not lag behind. Obviously, it is much simpler to click and drag an object from one window to another than to type “copy” at the command line with the corresponding attributes. In addition, the productivity of working at a computer significantly increases, which for many is a decisive factor.
Moreover, the situation in the field of information technology is such that it is now practically impossible to find a full-fledged system providing for work in text mode. Unless Linux without a graphical shell thanks to its Unix kernel can boast of such. At least for now. It is not surprising that if the mouse does not work, then this is tantamount to a small disaster. Small personal Armageddon.
In numerous forums, one often encounters the question of why the mouse does not work. Such a malfunction is quite widespread, so if you wish, you can find your own case. Although the reasons why the mouse does not work can be very different, in most cases it is possible to solve the problem by following universal recommendations. We will give them.
One of the most common causes is accidental damage to the wire from the device to the computer. To prevent pulling of the light mouse with a heavy tail, some manufacturers use a thin and light cord in their products. However, a good intention can lead to the fact that a slightly moved table will transmit the wire and damage the cores.
Sometimes it is enough to pull the cord too much, adjusting to break the conductors. For example, just such a controversial decision is used in A4Tech gaming mice. Thus, if the mouse does not work, then the test should begin with the most obvious - a visual inspection of the condition of the wire. Such a breakdown is very easily detected and eliminated.
For previous generations of "rodents", assembled on the basis of an infrared sensor, you can see if the red diode in the bottom of the mouse is on. If the computer is turned on, the system is loaded, and the LED does not work, then the range of possible reasons narrows to "electronics - cord - connector (port)". Diagnosing the port is also simple - you should connect the mouse to another free slot. And finally, it is useful to check it on another computer.
In addition to these hardware problems, there may be software problems. For example, there are allegations that after incorrect removal of the KIS antivirus, the mouse stops working. In this case, you need to check the UpperFilters registry key and remove everything from it except the value for mouclass.
Often users complain that the right mouse button does not work. Almost always, the cause of this is the mechanical breakdown of the microswitch (buttons). It is necessary to disassemble the case, carefully remove the desired button, purchase a new one and solder it to the board. As an option - swap rarely used under the wheel and faulty.
But if the mouse does not work on the laptop, then do not disassemble the case or go to the service center. The fact is that the built-in touchpad can be turned off / on by pressing a specific key combination (Fn and one of the F-ok). You need to read the instructions or deal with pictograms-tips.
