How to handle common problems with a mouse

Common mouse failures are as follows: mobility is not flexible, a certain direction of failure, keys do not work and the computer does not recognize the mouse and so on several situations.

　　1. Mobile Not flexible

Mobility is not flexible refers to the mouse when moving, the corresponding pointer on the screen does not follow the move. Under normal circumstances for a large mobile mouse, the cursor can move normally, but a small range of mobile mouse, the cursor can not move. Large mobile mouse work normally, and small move when the work is not normal, indicating the normal mouse installation, circuit work is normal, the reason is the rubber ball can not effectively drive the grating disk rotation. This is rubber ball, left and right axis, front and rear axle and support wheel is too dirty, causing the rotation is not flexible caused. This is the most likely failure of the mouse. The handling of the fault, as long as the removal of dirt can be. The specific treatment is to flip the mouse, according to the direction of the arrow counterclockwise rotation of the active floor, remove the active bottom plate and rubber ball, and then the roller and support wheel, rubber ball on the dirt clean, reload can return to normal. Optical mouse because there is no rotating rubber ball, there is no rotation of the roller, so there is no flexibility due to the rotation of the mouse movement is not flexible phenomenon. However, when the light tube or photosensitive tube accumulated dust too much, also may cause the mouse movement is not flexible.

　　2. Failure in One Direction

The mouse moves only in one direction, and the other direction does not work, indicating that there is no rotation in one direction, or that a corresponding set of light-emitting diodes and photosensitive transistors has at least one damage. For mechanical mouse treatment, first rotate the active floor, remove the active bottom plate and rubber ball, and then use the hand to rotate the roller directly, if there is a roller can not rotate, or rotation is more difficult, indicating that the failure is due to the roller has not been caused by the rolling of the ball. The rollers may not rotate because they are stuck in the dirt, clean the dirt to remove the fault, if the two rollers are flexible and rotate with the hand, the cursor can still only move in the left or right direction, the fault is the corresponding light-emitting diode or photosensitive tube damage. Unscrew the fixed screw of the mouse, open the outer cover, check the resistance between the two poles of the photosensitive tube on line, if the resistance varies with the light intensity of the photosensitive tube, the photosensitive tube is good, the damage is the light-emitting diode. Otherwise the photosensitive tube is damaged, replace the damaged parts, the fault can be ruled out.

　　3. The key does not work

The key does not work, generally for fretting switch damage. In the mouse fault, the micro-switch damage rate is relatively high, after the mouse movement is not flexible fault, especially the left button under the micro-switch because of frequent use, it is easy to damage. Mouse each button has a micro-switch, three-button mouse in the actual application, the middle one of the buttons generally do not use, the right button is also used less, so when the left button under the micro-switch damage, you can not use the middle of the micro-switch or rarely used on the right side of the micro-switch removed, replace the damaged switch, Failure can be ruled out. If the middle switch is removed, the use of the mouse is largely unaffected. If the use of the application of the mouse only a key, in the emergency treatment, can also use the Software method will be the right mouse to the left mouse, that is, you can use the right to replace the original left button to avoid the damage that a key.

　4. Computer does not recognize the mouse

Computer does not recognize the mouse is all the operation of the mouse does not work. The computer does not recognize the mouse for many reasons, may be the cause of the software, may also be the cause of the hardware. Software causes include viruses in the computer, incorrect installation of mouse drivers, conflicts between application software and mouse drivers, and more. For software reasons, you should first check that the mouse driver is installed correctly, that the computer has a virus, and then check that the application does not support the mouse you are using.

In the computer does not recognize the mouse hardware failure reason, the more common reason is the disconnection. Because the mouse is in constant motion, if the signal line quality is not good or pull force too large, it is easy to cause disconnection. In most cases, the breakpoint is at the end of the mouse, so there is disconnection, as long as the signal line mouse this end cut a small cut, and then again the line welding, the general can be ruled out fault.
