If the pointer on the screen does not move smoothly as you move the mouse, you might need to clean the mouse. The following steps apply to mice having a rolling ball type mechanism. Optical mice do not have a ball. If you have such a device, follow the manufacturer's ecommendations for care and maintenance.

To clean the mouse:

  1. Turn off the computer.
  2. Disconnect the mouse cable from the computer.
  3. Turn the mouse upside down. Unlock the retainer on the bottom of the mouse by rotating it clockwise until the arrow aligns with the unlock symbol.

    Some mouse types have retainers that are removed differently. If your mouse does not have lock and unlock symbols, move the retainer in the direction indicated by the arrow on the retainer.
  4. Place your hand over the retainer and turn the mouse right side up. The retainer and ball will drop into your hand.
  5. Wash the ball in warm, soapy water and dry.
  6. Using a damp cloth, wipe the outside of the mouse and the retainer. Be sure to wipe the rollers inside the mouse.
  7. Insert the ball and retainer. Lock the retainer by rotating it so the arrow is aligned with the lock symbol.
  8. Reconnect the mouse to the computer.
