Dell™ DualPoint™ Integrated Pointing Device
Cursor Pointing Devices
Your computer is equipped with the unique Dell DualPoint integrated pointing device. The DualPoint integrated pointing device supports two types
of cursor pointing devices (see
Figure 4 and Figure 5 ) that perform traditional mouse functions: the touch pad and the track stick. You can choose
to use the touch pad only, the track stick only, or both at the same time.
Two sets of buttons located above and below the touch pad enable you to perform standard mouse functions with your thumb without removing
your hands from the keyboard. You can also take advantage of the option to use "buttonless" selection features by clicking or double-clicking on
either the touch pad or the track stick.
DualPoint integrated pointing device software allows you to set the default for the type of cursor pointing device you want to use, as well as
sensitivity, motion, and drag-and-drop features of both the touch pad and the track stick.
Using the Dell DualPoint Integrated Pointing Device
The PS/2 touch pad (see Figure 4) detects the position of your finger over a touch-sensitive area to position the cursor within the display
screen. The touch pad provides the computer with full mouse functionality. The touch pad’s two buttons, located directly below the touch pad,
correspond to the left and right buttons on a standard mouse.
Figure 4. PS/2 Touch Pad
To best use the touch pad, use the following techniques:
l To move the cursor, lightly slide your finger over the smooth sensor area.
l To select an object, gently tap once on the surface of the touch pad or use your thumb to press the left touch pad button. The touch pad
buttons perform standard mouse functions.
l To select and move (or drag) an object, position the cursor on the object and double-tap on the touch pad. On the second tap, leave your
finger on the touch pad and move the selected object by sliding your finger across the surface.
l
To double-click an object, position the cursor on the object and then tap the touch pad or the left touch pad button twice.
Using the Track Stick
The track stick (see Figure 5) detects the pressure and direction that you move your finger when touching the track stick cap located near the
center of the keyboard. The two buttons located between the touch pad and the space bar on the keyboard correspond to the left and right buttons
on a standard mouse.

NOTE: When using the integrated keyboard, you press and the appropriate keys to perform certain functions. To
perform such functions on an external keyboard, you press and the appropriate keys. You must be sure
that the External Hot Key option is enabled in the System Setup program.
NOTES: When enabled, the DualPoint integrated pointing device (whether touch pad only, track stick only, or both) uses
interrupt request (IRQ) 12. No other device can use IRQ12 while the DualPoint integrated pointing device is enabled.
When you attach an external Personal System/2 (PS/2)-mouse to the computer, the DualPoint integrated pointing device
is automatically disabled.
