DualPoint Integrated Pointing Device: Dell™
Latitude™ CPx H-Series/J-Series User's Guide
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.
 |
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 PS/2-mouse to the computer, the
DualPoint integrated pointing device is automatically disabled. |
The Personal System/2 (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 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:
- To move the cursor, lightly slide your finger over the smooth sensor
area.
- 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.
- To select and move (or drag) an object, position the cursor on the
object and tap down-up-down on the touch pad. On the second down motion, leave your finger
on the touch pad and move the selected object by sliding your finger across the surface.
- To double-click an object, position the cursor on the object and then
tap the touch pad or the left touch pad button twice.
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.
Figure 2. Track Stick
To best use the track stick, use the following techniques:
- To move the cursor, apply pressure to the track stick with your right
or left index finger. Press up or down to move the cursor to the top or bottom of the
display screen. Press left or right to move the cursor to the left or right of the
display screen.
- To select an object, tap once on the track stick or use your thumb to
press the left track stick button. The track stick buttons perform standard mouse
functions.
- To select and move (or drag) an object, position the cursor on the
object. Then press and hold the left track stick button. Leave your thumb on the
button and move the selected object by pressing the track stick in the desired direction.
- To double-click an object, position the cursor on the object and then
tap the left track stick button twice or tap the track stick itself twice. The track
stick functions much like the touch pad in that it allows you to use buttons for mouse
functions or the pointing device itself.
The 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.To
customize the DualPoint integrated pointing device, perform the following steps:
- Click the Start button, point to Settings, and click Control
Panel.
- Double-click the Mouse icon to open the Mouse
Properties window and click the Touch tab.
- Select the settings that work best for you and click Apply.
- Click OK to save the settings and close the window.
You can also click the touch pad icon on the taskbar and click Touch
Pad Properties to open the Mouse Properties control panel.
Your computer came with four additional track stick caps in assorted
colors. You may need to change the track stick cap if it wears down from prolonged use.
To change the track stick cap, perform the following:
- Pull the cap off the track stick (see Figure 3).
Figure 3. Removing the Track
Stick Cap
- Align a new cap over the square track stick post and gently press the
cap down onto the post.
- Test the track stick to ensure that the cap is seated properly.
