The mouse failure analysis and maintenance

The mouse hp pavilion dv6 3011so laptop keyboard failure analysis and maintenance is simple, most of the fault for interface or key bad contact, broken line, mechanical positioning system smudginess. A few fault for the mouse internal components or circuit virtual welding, it mainly exists in some inferior products, especially the light emitting diode, IC circuit damage is in the majority.

A, can not find the mouse

1, mouse completely damaged, need to replace the new mouse.
2, the mouse hp pavilion dv6 3012eg laptop keyboard and host connected a serial port or PS / 2 port bad contact, carefully pick good line, restart the can.
3, on the main board of the serial port or PS / 2 port damage, this kind of situation is very rare, if that's the case, had to replace a main board or the use of multi-function card on the serial port.
4, the mouse line contact undesirable, this kind of situation is the most common. Poor contact point in mouse internal wire and the joint of the circuit board. Fault as long as not to PS / 2 layup, general maintenance up easy. Usually because line is very short, or is mixed and disorderly and lead to the mouse line was the cause of the pulling force, the solution is to will open the mouse, then use solder iron will spot welding is good. Still have a kind of circumstance is the mouse line internal bad contact, is due to long time caused by aging cause, the fault is usually difficult to find, replace the mouse is the fastest solution.

Second, the mouse can show, but unable to move

The mouse hp pavilion dv6 3015tx laptop keyboard flexibility drops, the mouse pointer not as before follow one's inclinations, but slow response, positioning inaccurate, or simply can't move. This is mainly because the mouse in the mechanical positioning rolling shaft accumulation too much dirt and lead to drive failure, causing rolling not flexible. Maintenance of the emphasis on mouse internal X axis and Y axis of the transmission mechanism. The solution is that can open rubber ball lock plate, the mouse rolling the ball off, with a clean cloth dipped in neutral detergent for rubber ball cleaning, friction shaft, etc can be used by alcohol to scrub. Best in the axis place on drop a few sewing machine oil, but must be careful, don't flow to the friction surface and code disc gate sew the. After all the dirt removal, the mouse flexibility back again.

Third, the mouse button failure

The mouse button without action, this may be because the mouse hp pavilion dv6 3060sa laptop keyboard button and circuit boards micro switch distance too far or click on the switch after a period of use and reduced ability to rebound. Disconnect the mouse, when the mouse button below stuck on a moderate thickness of plastic sheet, thickness according to the actual need and determine, after the completion of treatment can be used
