charges the battery. The AC input voltage can range from 100 to 240 volts so that
.you can use the notebook with the appropriate plug adapter.
The AC power cord included with the notebook is appropriate for the
voltage of your local area. If you attempt to connect the notebook to a
wall outlet other than in your local area, check the voltage of the outlet
and use an ACpower cord appropriate for the outlet.
You can also install the AC adapter into the left-side bay. Refer to the section of
Installing a Bay Unit in this chapter for details.

2-2 Basic Operations

Operating GlidePoint
Your notebook is provided with an integrated pointing device called GlidePoint.
Through GlidePoint, you can move the pointer, select an item among the menu, etc.
just like with a mouse. GlidePoint is also compatible with a PS/2 mouse.
l Do not hit or scratch the surface of the GlidePoint with pointed objects
(such as a ballpoint pen).
l Do not operate the GlidePoint with a moist finger. This may cause
GlidePoint to operate incorrectly.
_
Using the GlidePoint
Take a moment to become familiar with how the GlidePoint works.
Place Your Fingertip
Place your left or right hand next to the GlidePoint, resting your wrist naturally in a
relaxed manner. Place your thumb or finger on the GlidePoint.
Move Your Fingertip
The rectangular pad of the GlidePoint acts like a miniature duplicate of the display.
As you slide your fingertip across the pad, the pointer on the screen moves in the
same direction across the screen. The GlidePoint is very sensitive, and you do not
have to exert a lot of pressure on the pad. GlidePoint will respond to a light touch
from your fingertip.
Basic Operations 2-3

Click, Double-click, and Right-click
To click, double-click, or right-click, you can use the left or right button just like
those of a mouse. Instead of clicking by pressing the left button, you can just tap
gently anywhere on the rectangular pad of the GlidePoint. For double-clicking, tap
twice gently.
J
Drag and Drop
You can move icons or windows by using “drag and drop.”
1. Position the pointer over the object such as an icon or window.
2. Press the left button; do not release it.
3. Holding down the button, move the pointer. The object moves together with
the pointer.
4. Release the button when the object comes to the appropriate place.
V
.
You can also drag and drop by tapping the GlidePoint.
1. Position the pointer over the object.
2. Gently tap twice on the pad.
3.
On the second tap, keep your finger in contact with the pad.
4. Holding down the button, move the pointer. The object moves together with
,,
the pointer.
5. Release the button when the object comes to the appropriate place.
J
Changing the Configuration
You can change the configuration of the GlidePoint, such as swapping left and right
buttons, changing the pointer size, etc. To adjust the configuration:
ti
1.
From the Start menu, select Settings - Control Panel.
J
2. Double-click the Mouse icon. The Mouse Properties window opens.
d
Q!m
l If you swap the left and right buttons,
“ tapping” on the GlidePoint as
an alternative method ofpressing the left button will no longer
function.
\/
l Your finger or palm may unconsciously touch the GlidePoint. This
touching is recognized as “tapping” or click, and the system works as
ifyou click. To avoid this inconvenience, you can disable the tapping
function in the Mouse Properties window. Select Tapping, uncheck
./
Tapping, and click OK
.
