Cursor Pointing Devices
Your Dell portable 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 1 and Figure 2 ) 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 you thumb without removing your
hands from the keyboard. You can also take advantage of "button-less" selection by simply 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 track stick.
Using the Touch Pad
The PS/2 touch pad (see Figure 1 ) 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 1. 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 2 ) 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.

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.
