The pointer doesn't move smoothly on the screen

Try cleaning your pointing device to restore optimum performance.

If you have a pointing device with the IntelliEye optical sensor and the LED port on the bottom of the device is dirty, then the light beam cannot work properly. When the IntelliEye optical sensor is obstructed, your device may not work correctly. See Clean your mouse to clean the IntelliEye optical sensor.

If you have a device with a ball and the inside is dirty, the ball and rollers inside can't operate smoothly, causing your pointer to jump around on the screen. See Clean your mouse or Clean your trackball to clean your device.

Note

The IntelliEye optical sensor works best on surfaces with texture, for example, white paper, laminated desktops, wood, and synthetic wood. Glass or shiny surfaces, for example, mirrors or glossy white paper, may prevent the IntelliEye optical sensor from working correctly. In these instances, try a mouse pad, piece of paper, or other textured surface.
