computer failure of the mouse <br> ★ ★ <BR> <BR> Posts failure analysis and maintenance of the mouse is relatively simple, most of the fault for the bad interface or buttons, disconnection, mechanical positioning system dirty. .A small number of failures for the internal components or circuit Weld mouse, which are found in certain low-quality products, especially in the light-emitting diode, IC circuit is damaged the majority. .<BR> <BR> A common failure: can not find the mouse <BR> <BR> 1. Mouse completely damaged and need replacement mouse. .<BR> <BR> 2. Mouse connected to the host serial port or PS / 2 oral exposure bad, carefully take a good line, you can restart. .<BR> <BR> 3. Motherboard serial or PS / 2 ports from getting damaged, this situation is rare, if this is the case, had to replace a motherboard or a serial port on the multi-purpose card. .<BR> <BR> 4. Mouse line is bad, this is the most common. .Poor contact points as the mouse inside the wire and circuit board connections. .Failure as long as not another PS / 2 joints, the general is not difficult to repair. .Usually due to relatively short lines, or compare the mouse lines are messy and hard pulling causes the reason, the solution is to open the mouse, and then use a soldering iron to solder weld. .There is another situation that is bad inside the mouse cable is caused by the long time due to the aging, and this failure is often difficult to find, replace the mouse is the fastest solution. .<BR> <BR> Troubleshooting II: the mouse can be shown, but can not move <BR> <BR> the flexibility of the mouse down, mouse pointer not as arbitrary, but slow, inaccurate positioning, or simply can not move .the. .This is mainly due to mechanical positioning the mouse scrolling axis in the accumulation of transmission failure caused by excessive dirt, resulting in rolling is not flexible. .Maintenance of the internal focus on the mouse X axis and Y axis on the transmission mechanism. .The solution is to open the plastic ball locking plate, remove the mouse ball to roll, with a clean cloth dipped in mild detergent to clean the rubber ball, the friction shaft can be cleaned with alcohol. .Axis at the best drop a few drops of sewing machine oil, but it must be careful not to flow to the friction surface and the seam on the grid encoder. .After all the dirt will be removed, the flexibility of the mouse ever resume. .<BR> <BR> Three common faults: the mouse button failure <BR> <BR> 1. The mouse button without movement, this may be because the mouse button and the circuit board micro switch is too far away or click on the switch after a period of .reduced ability to use the rebound. .Open the mouse, the mouse buttons below the moderate thickness of glue a piece of plastic film, the thickness is determined according to actual needs, can be used after treatment. .<BR> <BR> 2. The mouse button is not the normal pop-up, this may be because when the key switch in the bottom of the bowl-shaped micro-fracture caused by exposure to film, especially the long-term use of plastic is easily broken reed. .If it is three-button mouse, you can remove the middle of that one key to the emergency. .If it is good quality original brand-name mouse, you can solder, the open micro switch, carefully clean the contacts, some of the grease, the bottles can be used. .<BR> <BR>.
