Computer mouse common problems and solutions?
The fault analysis and maintenance of the mouse is relatively simple. Most of the faults are poor interface or button contact, wire breakage, and mechanical positioning system. A few faults are the internal components or circuits of the mouse, which are mainly found in some inferior products, especially LEDs and IC circuits.
Common fault one: no mouse found
1. The mouse is completely damaged and a new mouse needs to be replaced.
2. The mouse and the host are connected to the serial port or the PS/2 port is not in good contact. After carefully connecting the cable, restart it.
3. The serial port or PS/2 port on the motherboard is damaged. This is rare. If this is the case, you have to replace one motherboard or use the serial port on the multifunction card.
4. Poor contact on the mouse line is the most common. The point of poor contact is mostly at the junction of the wire inside the mouse and the board. As long as the fault is not at the PS/2 joint, it is not difficult to repair it. Usually because the line is short or messy, the mouse line is pulled hard. The solution is to open the mouse and solder the solder joint with a soldering iron. Another situation is that the internal contact of the mouse cable is poor, which is caused by aging caused by long time. This kind of fault is usually difficult to find, and replacing the mouse is the fastest solution.
Common fault 2: The mouse can display but cannot move
The flexibility of the mouse is reduced, and the mouse pointer is not as free as it used to be, but rather unresponsive, inaccurately positioned, or simply unable to move. This situation is mainly caused by excessive accumulation of dirt on the mechanical positioning scroll axis in the mouse, which causes the transmission to malfunction, resulting in inflexible scrolling. The focus of the repair is on the X-axis and Y-axis drive mechanisms inside the mouse. The solution is to open the rubber ball lock piece, remove the mouse rolling ball, clean the rubber ball with a clean cloth and a neutral detergent, and rub the friction shaft with alcohol. It is best to drop a few drops of sewing machine oil on the shaft, but be careful not to flow to the friction surface and the code grid. After all the dirt is removed, the flexibility of the mouse is restored.
Common fault three: mouse button failure
1. The mouse button has no action. This may be because the mouse button and the micro switch on the board are too far away or the click switch is used for a period of time and the rebound ability is reduced. Disassemble the mouse and attach a plastic piece of moderate thickness to the bottom of the mouse button. The thickness should be determined according to actual needs. It can be used after processing.
2. The mouse button cannot be bounced normally. This may be caused by the breakage of the bowl contact piece in the micro switch under the button, especially when the plastic reed is easily broken after long-term use. If it is a three-button mouse, you can remove the middle button to take emergency. If it is a good quality original brand mouse, you can weld it, remove the micro switch, carefully clean the contacts, and put some grease on it before you can install it.
