1. Check the cable of the mouse to ensure that it is properly connected to the computer. Also ensure that is it not excessively twisted or bent.

2. If the connection is tight and secure, observe the bottom of the mouse and find out which direction to rotate the mouse cover.

3. Rotate the mouse cover in the proper direction and remove it.

4. Clean the mouse pad with a damp cloth. A clean mouse pad helps the mouse to move in a smooth manner.

5. If the mouse still does not function properly, repeat the cleaning process.

6. Try to connect the mouse to another computer and check if it works. Also, cross- check by connecting another mouse to the computer.

10. If the mouse does not function properly even after repetitive cleaning, it is possible that there is a hardware problem with the mouse. In this case, contact the manufacturer or replace the device.

11. In case of optical mouse, check the surface on which mouse is placed. It should not be shiny or reflective e.g. mirror as DSP cannot work properly on these surfaces.

2. Dab one or two drops of head cleaning solution on the left switch.

3. Use a small minus screw driver to press the button twice or thrice to soften the switch.

4. Reassemble the mouse and check whether the problem has resolved.

5. Otherwise replace the left button switch with the right one by disordering and soldering the same as right button switch is less used compared to the left one.
