The mouse pointer stops moving periodically, only moves in one direction, or moves erratically

If the mouse moves erratically, the mouse needs to be cleaned or should be used on a different surface.

  • If you have an optical mouse , use the following steps to clean the mouse.
    1. Wipe the body of the mouse and mouse cord with cleaning wipes or a cloth and cleanser.

This can happen with an optical mouse being used on a glossy surface. Use a mouse pad to correct the problem.

Moving the mouse does not move the pointer

Perform the following steps, in order, until a solution is found:
NOTE: This document does not cover DOS. Mice are not compatible with DOS unless a special driver is used.
  1. If the mouse is a PS/2 mouse (identified by a round connector on the end of the cable), make sure the mouse is connected to the mouse port, not the keyboard port. The colors of the cable plugs and the colors of the connector labels should match. Reconnect the mouse and keyboard cables only when the computer is off.
  2. With the computer off, connect a regular PS/2 mouse or serial mouse in place of the scroll mouse to see if there is something wrong with the computer or the identification of the mouse. If the regular mouse is not found or does not work, then the issue is not with the mouse but with the PS/2 port or serial port. If the mouse works properly after the computer is turned on, then continue to the next step.
  3. Try using the mouse on another PC with Windows. If the mouse fails, it is probably bad and should be replaced.
  4. If the mouse worked previously, a software update or configuration problem might exist. Use Microsoft System Restore to go back to the last time the mouse was known to be working properly. For instructions on how to use Microsoft System Restore, refer to one of the following HP support documents that applies to your computer and version of Windows:
  5. Use HP Recovery Manager to restore the mouse drivers. For more information, see the HP Support document Using HP Recovery Manager to Restore Software and Drivers (Windows 7) .
