Dell Latitude LM Reference and Troubleshooting Guide - Page 21

NOTE: The battery is designed to work only with Dell Latitude LM computers. Do not attempt to use the battery with other computers. WARNING: Do not puncture or incinerate the battery or dispose of it in a landfill. Instead, return the battery to Dell for proper disposal or recycling. • Cache memory that enhances the speed of many microprocessor operations by storing the most recently accessed contents of system memory. Your computer has 16 kilobytes (KB) of internal cache on the microprocessor and 256 KB of static randomaccess memory (SRAM) level 2 (L2) cache. • Eight megabytes (MB) of nonremovable memory on the system board. Memory can be increased to a maximum of 40 MB by installing matched pairs of 4-, 8-, or 16-MB memory modules. • Three power conservation modes-standby mode, 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. • A special options bay that extends the functionality of your computer by letting you use a CD-ROM drive, a diskette drive, or an optional secondary battery. • Support for up to two 3.3-volt (V) or 5-V PC Cards that adhere to the standards of the Personal Computer Memory Card International Association (PCMCIA). The computer supports up to two type I or type II cards (in any combination) or one type III card. Dell-installed device drivers on the hard-disk drive support the operation of many standard PC Cards. The Card Manager utility automatically recognizes most installed PC Cards and lets you reconfigure them as needed. • A basic input/output system (BIOS) that resides in flash memory and can be upgraded by diskette. A BIOS upgrade, if required, can be obtained on diskette from Dell or can be downloaded from Dell's TechConnect BBS. • High-performance parallel and serial ports, and a multipurpose Personal System (PS)/2 connector for attaching external devices. There is also a monitor connector for attaching an external monitor to your computer. • A PS/2-compatible touch pad that gives your com- puter full mouse functionality. • An infrared port for use with compatibile external devices. The infrared port permits file transfers without using cable connections. Software Features Dell has installed the Microsoft® Windows® 95 operating system or the Microsoft Windows 3.x/MS-DOS® 6.x operating system on your hard-disk drive. The following software is also included with your Dell computer: • A Setup program and system utilities that let you customize the operation of your computer. For more information, see Chapter 2, "Customizing System Features," and the "Software Features" section of the online System User's Guide. NOTE: The system utilities are available separately on diskettes from Dell for customers who installed their own version of Windows 95 or Windows 3.x. See Chapter 5, "Getting Help," for the appropriate telephone number in your location. • The Dell diagnostics for evaluating your computer's components and devices. For more information, see Chapter 4, "Running the Dell Diagnostics." After you turn on your computer the first time, accept the software licenses agreement. Then complete the installation of your operating system. Next, use the Dell DiskMaker in the Dell Accessories folder or group to create program diskette sets and back up your software support (system) utilities. A program diskette set contains the complete software package on diskettes. These diskettes can be used to reinstall or reconfigure the software if necessary. The online instructions in the Dell DiskMaker tell you how many blank diskettes are needed. Introduction 1-3
