such as communicating over a telephone or
connecting to a network.
The computer has built-in slots that support one
Type III or two Type II/I PC Cards. Type III PC
Cards must be inserted into the lower slot.
Your Extensa computer is designed to support

Your Extensa computer supports standard
analog external monitors with resolutions up to
1280 x 1024 modes. The computer also
supports DDC compatible monitors allowing you

meet the Energy Star standards).
When the computer is connected to an external
monitor, you can use the computer with the
display closed.
You can also display images on the external and
internal display at the same time. This feature

LCD, CRT, or both by using the Fn+F12 hot key.

the Extensa.
 To connect a serial mouse, attach the
connector to the 9-pin serial port in the rear
of the Extensa.

device. For Windows 95 to detect a serial mouse,
use the Add New Hardware icon in the Control
Panel.
