Using The Touchpad - HP Pavilion DV4000 Hardware And Software Manual

Using the TouchPad

In Windows the TouchPad provides the navigation, selection, and
scroll functions of an optional external mouse.
To move the pointer, slide your finger across the TouchPad
surface in the direction you want to move the pointer.
To execute the click functions of the left or right button on
an external mouse, press the left or right TouchPad button.
To scroll up or down, slide your finger up or down in the
TouchPad scroll zone.
The TouchPad is enabled when the notebook is turned on. If you
work with keystrokes rather than mouse actions, you may prefer
to disable the TouchPad to prevent accidental TouchPad activity.
