Troubleshooting the Mouse and Touchpad
If the pointer does not move while playing a disc, press Ctrl+Alt+Delete
simultaneously to stop playback and restart the notebook.
If you are still experiencing problems, check that another mouse was not
installed.
You may need to use your supplied Driver Recovery CD to reinstall the
touchpad or mouse drivers. See "To use the System Recovery CD(s)" for
more information.
