Страница: 23 / 136

Introduction 1-3
installing combinations of 16-, 32-, and 64-MB
3.3-volt (V) EDO small-outline, dual-inline memory
modules (SoDIMMs) in the two memory module
sockets on the system board.
•
A 256-kilobyte (KB) static random-access memory
(SRAM) external cache (also called level 2, or L2,
cache) on the Latitude CP M133ST and Latitude CP
M166ST. The Latitude CP M233ST and Latitude CP
M233XT have a 512-KB SRAM external cache.
Cache memory enhances the speed of many micro-
processor operations by storing the most recently
accessed contents of system memory.
•
Two power conservation modes—suspend mode and
suspend-to-disk mode—which help you conserve battery
power. If the batteries run out of power, suspend-to-disk
mode prevents data loss by copying all system data to the
hard-disk drive and turning off the computer.
•
Connectors for two 3.3-volt (V) or 5-V PC Cards.
The upper PC Card connector supports zoomed
video PC Cards.
NOTE: The PC Card controller supports the
CardBus standard for 32-bit data transfer on the
PC Card.
•
Hardware and software support for the Dell Latitude
C/Port Advanced Port Replicator (C/Port APR) and
the Dell Latitude C/Dock Expansion Station.
•
A touch-pad pointing device positioned for both left-
and right-handed users. The left and right touch-pad
buttons mimic mouse buttons; you can also perform
many pointing functions by tapping the touch pad
itself. “Click and drag” buttonless functions are also
supported.
•
A lithium ion battery standard in the battery bay,
with support for a second battery in the modular bay.
ExpressCharge technology charges a single battery
in 1 hour (when the computer is off or in suspend
mode).
NOTE: The batteries are designed to work only with
Dell Latitude CP portable computers. Do not use
the batteries with other computers, and do not use
batteries from other computers with the Dell Lati-
tude CP.
•
High-performance parallel and serial ports, and a
multipurpose Personal System/2 (PS/2) connector
for attaching external devices. There is also a moni-
tor connector for attaching an external monitor to
your computer, and a USB connector that supports
standalone and hub devices.
•
An infrared port that permits file transfer without
using cable connections. The port is compatible with
the Infrared Data Association (IrDA) Standard 1.1
(Fast IR) and Standard 1.0 (Slow IR) for use with
external devices.
•
An integrated 16-bit audio controller that provides
sound functions and is Sound Blaster Pro-compatible.
•
An automatic thermal management system that uses
a variable-speed fan and microprocessor speed
changes to keep the system running at the optimum
temperature.
The following software is included with your Dell
computer system:
•
The Microsoft
®
Windows
®
95 or Windows NT
®
4.0
or higher operating system is installed on your hard-
disk drive. For more information, see your operating
system documentation.
•
The System Setup program lets you view and change
the system configuration. For more information,
search on “System Setup program” in the online Sys-
tem User’s Guide or see Chapter 2, “Customizing
System Features.”
•
The Program Diskette Maker, which allows you to
create program diskette sets of software that Dell
installed on your computer’s hard-disk drive.
•
Dell Diagnostics for evaluating the computer’s com-
ponents and devices.
WARNING: Do not puncture or incinerate the
battery. When your battery no longer holds a
charge, call your local waste disposal agency or
environmental agency for advice on disposing
of the computer’s lithium ion battery. The lith-
ium ion technology used in the battery is
significantly less hazardous to the environment
than the lithium metal technology used in some
other batteries (such as watch batteries).
