Common mouse malfunction analysis and maintenance skills

Mouse fault analysis and maintenance is relatively simple, most of the fault for the interface or key touch bad, disconnection, mechanical positioning System dirty. A few faults for the mouse internal components or circuit virtual welding, which mainly exists in some inferior products, especially light-emitting diodes, IC circuit damage in the majority.

One, can not find the mouse

1. The mouse is completely damaged and needs to be replaced with a new mouse.

2. Mouse and host connected serial port or PS/2 mouth contact is bad, carefully connect the line, restart can be.

3. The motherboard of the serial port or PS/2 mouth damage, this situation is rarely seen, if this is the case, had to replace a motherboard or use a multi-function card on the serial port.

4. Poor contact with the mouse line, this situation is the most common. The point of contact is much more in the mouse internal wiring and circuit board connection. Fault as long as not ps/2 joints, general maintenance is not difficult. Usually because the line is relatively short, or more messy and lead to the mouse line is pulled forcibly pull the reason, the solution is to open the mouse, and then use the electric iron will weld spot welding well. There is also a situation is the mouse line internal contact is bad, due to the long time caused by aging, this fault is often difficult to find, replace the mouse is the fastest solution.

Second, the mouse can show, but can not move

The mouse's flexibility drops, the mouse pointer is not as arbitrary as before, but unresponsive, inaccurate positioning, or simply can not move. This situation is mainly because the mouse in the mechanical positioning of the rolling shaft on the accumulation of excessive dirt and lead to transmission failure, resulting in rolling inflexible. Maintenance of the focus on the mouse inside the x-axis and y-axis of the transmission mechanism. The solution is, you can open the glue ball lock piece, the mouse rolling ball unloading, with a clean cloth dipped in neutral detergent on the rubber ball cleaning, friction shaft can be used to scrub alcohol. It is best to drop a few drops of sewing machine oil at the pivot point, but be careful not to flow to the friction surface and the code plate grate. After the removal of all dirt, the flexibility of the mouse restored as ever.

Third, mouse button failure

1, mouse button No action, this may be because the mouse button and the micro-switch on the circuit board is too far away or click on the switch after a period of time of use and rebound ability to decline. Open the mouse, in the mouse button under the sticky piece of plastic thickness, thickness to be based on the actual need to determine, after processing can be used.

2, the mouse button can not normally bounce, this may be because when the button under the micro-switch in the bowl-shaped contact sheet fracture caused, especially the plastic reed long after the use of easy to break. If it is a three-button mouse, then you can remove the middle of the key to emergency. If it is a good quality of the original brand mouse, you can weld, take apart the micro-switch, carefully clean contact, on some grease, installed can be used.
