Why can not I move the mouse

Users questions: After two months of summer vacation, my mouse would not normally use. USB host interfaces behind the plug had four, but the mouse does not take a few minutes not always active, and repeatedly put a lot of times really depressed. You know how to solve a friend, in the hope that with your help, thank you. 77 7777 mouse problems occur most of the mouse's own problem and needs to another computer for testing, first rule out the mouse's own problems. If you fix the system because what system (repair system comes with the drive). 1, boot into safe mode press F8 at the exit, restart or shut down in an open election Machine, you can enter normal mode (fix registry). 2, If the malfunction persists, please use the system comes with System Restore to restore to you the fault does not appear when the repair (if the normal mode of recovery fails, boot into safe mode press F8 to use System Restore.) 3, if the fault is still , Using the system disk repair, open a command prompt and enter SFC * SCANNOW carriage return (SFC and * a space between), insert the original system disk repair system, the system will automatically compare repair. 4, if the fault persists, set in the BIOS as the first boot device CD-ROM into the system safety Transfer to a plate press R to select "Repair Install" button. 5, if the fault persists, reinstall the operating system recommended. Optical mouse troubleshooting common method (a) optical mouse failure include: failure of the mouse button, can not find the mouse, the sensitivity variation, mouse, or often for no reason are not allowed to place positioning drift phenomenon. Photoelectric Failure for more than 90% of the mouse disconnected, buttons bad, dirty three types of optical system failures, but there are cold solder joint and the original damages. (1) cable core line break the cursor does not move or mainly for good times and bad, his hands touched the connection, the cursor jitter. Disconnection fault occurs in the general multi-plugs or cable terminations and other frequent Bending at this time jacket intact, from the surface, generally do not see the need to use multimeter. Cable core line break troubleshooting method is: open the mouse, plug the cable cable disconnect from the circuit board, according to wire color and pin good correspondence between labeled and then by a broken wire location of cut 5 cm-6cm or so, then the mouse cell line can be re-connected. (2) key failure fault mostly micro reed switch in the poor contact caused by fractures or internal, such failures can adopt another approach for the maintenance of a button. Replacement methods are: electric soldering iron under the mouse left, the key to remove the solder back to the middle button Left location. (3) optical mouse sensitivity variation is common failures, manifested in moving the mouse, the cursor response insensitive, do not listen to the command. Sensitivity variation was mainly due to aging of the LED, or light sensor, optical receiving system offset, focal length is not aligned, external light effects, the lens has dirt path Stained. For the LED, or light sensor failures caused by aging can be replaced the same type of LED or photodiodes. The optical receiver offset, focal length is not aimed at the failure location LED can be adjusted so as to restore the in situ until the cursor moves to the horizontal and vertical far the most sensitive. For the outside world Light of the failure can be caused by the lens cover the exposed part of the component of black paper to re-place the better. For the lens channel there is pollution, so that light can not be successfully reached the failure can be caused by ethanol scrub LED, lens and mirrors, photodiodes can surface. (4) positioning the mouse or often for no reason are not allowed Drift failure occurs mainly by the influence of stray light interference in the pulse or circuit, or IC crystal due to poor quality. Positioning the mouse are not allowed to drift or failure often occurs for no reason first check the circuit solder joints, especially in certain vulnerable to power the site, found that Weld welding points can be electric soldering iron. If you do not Weld, and check the crystal is normal, if not normal, replace the crystal can be. (5) The system can not find the mouse to cause the system diagnostics can not find the main reasons for the mouse the mouse is damaged, poor contact with the host mouse, mouse port on the motherboard is damaged, the mouse driver damage. The system can not find the mouse Fault diagnosis method is as follows, first of all in safe mode, and then restart the computer or the method used to restore the registry fix the mouse driver. If you do not solve the problem may be bad or hardware damage, you can receive another computer mouse test. Direct replacement of damaged normal mouse mouse.
