Mouse abnormal solution

In the normal use of the computer, we will always encounter some minor problems, such as the problem of abnormal mouse, using the mouse to cause some unpleasant episodes to us.

In fact, it’s nothing more than a few points. In the following, I will summarize the problems of the non-normal work of the mouse in the process of using the computer with my friends. I hope that I will have something for everyone. prompt.

1. Interrupt resource conflict between serial mouse (commonly known as: square mouth mouse, for PS/2 round mouse) and new type of graphics card (Geforce2 MX and later graphics card).

Some old users still have a serial mouse because of computer upgrades or merchant reasons. This kind of mouse can be used normally on any kind of motherboard with COM interface, but due to the technical content of the graphics card in the new years, especially the graphics card after Geforce2 MX, the graphics card takes up more interrupt resources, sometimes it will grab Interrupt with the COM port. So when this happens, there will be a hardware conflict —— the mouse can't work, shake, smash, etc. If we upgrade the old machine, it is best to use the PS/2 mouse, which will cause the mouse to work abnormally afterwards, causing trouble for everyone.

2. Interference from external radioactive signals.

Anyone who knows a little about hardware knows that computer hardware enters work at a certain frequency when it is working. Computers at work are most susceptible to external radioactive signals and cause abnormal work. Sometimes we find that the mouse has frequency jitter, accompanied by frequency wave sound and display jitter, which is mostly due to external strong radioactive signals. For example: high-power appliances and their lines, cell phone signals, and so on. To solve this kind of problem, we just need to keep the computer away from these things. If space is limited, we can connect a UPS or a voltage regulator rectifier in front of the computer line.

3, strong light interferes with the normal operation of the internal photo-transmitter and receiver tube of the mouse.

I don't know if you noticed that there is a translucent and a black tube on both sides of the drive wheel when cleaning the mechanical mouse. The two Dongdong are photoelectric emitters and one is the receiving tube. . When the mouse works, it is to cut the light regularly by the transmission wheel to generate an electrical signal to make the mouse work. If the quality of the mouse is not too hard or touched or dropped, it will not be tightly closed. When there is strong light from the outside, it will cause abnormal operation of the photoelectric emission and receiving equipment. At this time, we only need to cover the glare. It can be used normally. Solution: Wrap the optoelectronic device with black tape. Reminder: Some electronic components in computer hardware are afraid of glare, so don't put your computer in strong light when you use your computer.

4, the core wire in the cable is broken.

This kind of problem may not be imagined by everyone. In fact, it is not difficult to understand when you open the mouse. There are four core wires in the mouse cable, which is quite fine! The mouse line is at the exit end of the mouse. Bending a big dead bend, this allows us to fold the cable back and forth while using the mouse, and over time the core wire in the mouse cable is broken (scientific name: metal fatigue), but nothing can be seen outside. The main phenomena are: irregular movement of the mouse, sometimes the left and right clicks of the mouse, etc., when we move the mouse, such phenomena disappear or the mouse is fixed.

Solution:

1 If you are a soldering master, pull out the core wires in the mouse cable one by one, find the broken wires, and solder them; < Br>

2 If you are not very good at soldering, then we will replace the redundant USB cable connector in the chassis, throw the cable off, then dock the two wires, but remember the signal Do not mix the color of the line!

There are many reasons for the mouse to malfunction or work abnormally. Remember to find out the reason first.
