Mouse is a kind of input equipment of computer, and it is also an indicator of the vertical and horizontal coordinate positioning of computer display system. It is named "mouse" because it looks like a mouse. People may encounter the failure of the left mouse button in the process of using the mouse, which requires careful examination of the relevant reasons. So how to repair the failure of the left mouse button? Let's learn about it together.
Failure of left mouse button: poor contact of mouse wire
Use the mouse a little longer, or pull it hard for many times. One or several of the four wires in the mouse is broken, or the contact is poor. This breakpoint is generally not far in front of the mouse. You can know after a few tests. Click the right button while pressing the wire, and go forward a little bit. Of course, it's related to everyone's usage habits. Places that are often pulled or folded are easy to break. This is generally the mouse hardware fault can be disassembled to see if there is any bad contact, it's usually good to repair it.
The left mouse button does not reflect that it may be a hard disk problem. When the hard disk has a bad track, or there are too many fragments. This may be read by calling hard disk with virtual memory. In this case, the response will be slow. Use CHKDSK command. When cleaning up the fragments, if you find that there are many fragments in the file, move it to another disk, and move it back after sorting, which is effective and quick. The solution is to restart the computer and the fault disappears.
Left mouse button failure: the system is busy and does not respond
The mouse may be because the computer system is busy and can't respond. Maybe your system has been installed for too long, or the software is installed too much, the registration form is too big and garbage is too much, or you haven't done disk cleaning for a long time, or you have installed multiple software with right-click menu attached, or the antivirus software settings are too conservative. The solution can be tried to optimize the computer system.
Maybe it has something to do with some services of the system, such as file system, which causes system delay. Many users like to improve the system speed as much as possible, and disable some mouse services. This needs to carefully check the relevant settings to find out the problem, so as to better solve it.
Solutions to common mouse faults
Mouse 1. Inflexible movement
Inflexible movement means that when the mouse moves, the corresponding pointer on the screen does not follow the movement. Generally speaking, when the mouse is moved by a large margin, the cursor can move normally, but when the mouse is moved by a small margin, the cursor cannot move for the most part. The mouse works normally when it moves in a large range, but not when it moves in a small range, indicating that the mouse is installed normally and the circuit works normally. The reason for the failure is that the rubber ball can not effectively move the grating plate. This is due to the dirty rubber balls, left and right shafts, front and rear shafts and supporting wheels, which cause inflexible rotation. This is the most likely mouse failure.
To deal with this fault, only the dirt can be removed. The specific treatment method is to turn the mouse over, rotate the movable floor anticlockwise according to the direction indicated by the arrow, take down the movable floor and rubber ball, then clean the dirt on the roller, supporting wheel and rubber ball, and then reassemble it to restore normal. The photoelectric mouse has no rubber ball or roller, so there is no inflexible phenomenon of mouse movement caused by inflexible rotation. However, when there is too much dust on the light-emitting tube or photosensitive tube, it may also cause the mouse to move inflexibly.
2. Failure in one direction
The mouse only moves in one direction, while the other direction does not work, indicating that the roller in one direction does not rotate, or the corresponding set of LED and phototriode have at least one damage. When dealing with the mechanical mouse, first rotate the movable bottom plate, take down the movable bottom plate and the rubber ball, and then directly rotate the roller by hand. If there is a roller that cannot rotate, or it is difficult to rotate, it indicates that the fault is caused by the roller not rolling with the ball.
The reason why the roller can't rotate may be that it is stuck by the dirt, and the dirt can be cleaned up to eliminate the fault; if both rollers rotate flexibly, and the cursor can only move in the left and right or vertical directions when turning the roller by hand, the fault is that the corresponding LED or phototube is damaged. Unscrew the fixing screw of the mouse, open the outer cover, and check the resistance between the two poles of the photosensitive tube online. If the resistance changes with the intensity of the light on the photosensitive tube, the photosensitive tube is good and the LED is damaged. Otherwise, the photosensitive tube is damaged. Replace the damaged parts, and the fault can be eliminated.
3. Key does not work
The key does not work, generally the microswitch is damaged. In the mouse failure, the damage rate of microswitch is relatively high, next to the mouse movement inflexible failure, especially the microswitch under the left button is easy to damage due to frequent use. There is a microswitch under each key of the mouse. In practical application, the middle key of the three button mouse is generally not used, and the right key is also used less. Therefore, when the microswitch under the left key is damaged, the middle microswitch that is not used or the right microswitch that is rarely used can be removed to replace the damaged switch, and the fault can be eliminated 。
If you remove the microswitch in the middle, it has no effect on the use of the mouse. If only one key of the mouse is used in the application software, the right mouse can also be changed to the left mouse by software method during emergency handling, that is to say, the right mouse can be used instead of the original left key to avoid the damaged one.
4. Computer does not recognize mouse
Computer does not recognize mouse means that all operations of mouse do not work. There are many reasons why the computer doesn't recognize the mouse, either because of software or hardware. The software causes include computer virus, incorrect installation of mouse driver, conflicts between application software and mouse driver, etc. For software reasons, you should first check whether the mouse driver is installed correctly; whether the computer has a virus; and then check whether the application software does not support the mouse used.
Among the reasons that the computer does not recognize the mouse hardware failure, the more common reason is the disconnection. Because the mouse is in constant motion, if the signal line quality is not good or the pulling force is too large, it is easy to cause disconnection. In most cases, the breakpoint is at the end of the mouse, so after the broken line occurs, as long as a small section of the signal line at the end of the mouse is cut off, and then the line is soldered again, the fault can be generally eliminated.
