We all know that the mouse is divided into left and right buttons and the middle wheel. The mouse wheel is the most frequently used when we slide up and down while browsing the web. After a long time of use, the mouse wheel will fail due to mechanical aging and metal oxidation. How to solve this problem? Here are some methods to solve the problem of mouse wheel failure.
Method 1: Modify the registry
Click the Start menu in the lower left corner, click the Run button, and then enter regedit. You can also call up the Run box by using the shortcut key "win+r". Then in the registry editor, expand HKEY_ CURRENT_ Find the USERControl PanelDosktop on the right side and double click to open WheelScrollLines, and change the data value to 3. Then restart the computer and try to see if the mouse wheel is restored.
Method 2: Repair the software with the mouse wheel
Two such software are free, DoubleClickFix and MouseInc
Their core principle is to shield redundant mouse scrolling operations. For example, when we roll forward, the mouse does roll back. At this time, the software can shield backward scrolling operations, so as to achieve the purpose of repair. You can see that there is an option to block invalid scrolling.
Method 3: Disassemble the mouse for repair
The above method is to cure the symptoms but not the root cause, while this method is to cure the root cause, it is difficult and suitable for people with strong practical ability. Let's teach you.
1. We need to use a plum screwdriver. The screw hole on the mouse is usually under the label or under the gasket. If it is a snap on the mouse, open it with a flat screwdriver.
2. When removing, note that the battery cable is connected to the two enclosures. Don't pull it off. Then we can see the circuit board of the mouse. For the scroll wheel, we need to remove the screws on the circuit board to facilitate cleaning.
3. The core of the mouse wheel is the encoder shown in the figure below. We need to spray the rust remover.
5. If simple cleaning is not enough, then we need to disassemble the encoder. See the blue plastic sheet? Use a flat screwdriver to pry several clips on it to loosen it. After the blue gasket is loose, the black gear and an iron sheet can be taken out. This iron sheet is used to make the pulley feel better when it rotates, and the contact is on the black gear
6. Then we use cotton or toilet paper to wipe the three copper pieces on the black gear, and then use a screwdriver to pick them out, which can make the contact more sensitive. It's OK to pick a large range here, and it will be automatically flattened when it is installed back.
Conclusion: Methods 1 and 2 are simple software repair methods, so we don't need to pay attention to anything. Method 3 needs to pay attention to the details. Don't damage the mouse wheel. However, even if it is broken, it is impossible to replace a mouse. If you operate properly, the above method can definitely solve the problem of mouse wheel failure, and it is also a relatively efficient and cost free solution.
