Dell 3000 manual Introduction

The battery is designed to work only with Dell Inspiron 3000 computers. Do not attempt to use the battery with other computers.

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).

•Cache memory that enhances the speed of many microprocessor operations by storing the most recently accessed contents of system memory. Dell Inspiron 3000 M166ST computers have 32 kilobytes (KB) of internal cache on the microprocessor and 256 KB of static random-access memory (SRAM) level 2 (L2) cache. Dell Inspiron 3000 M200ST and M233XT computers have 512 KB of SRAM L2 cache.

•Sixteen megabytes (MB) of nonremovable memory on the system board. Memory on any Dell Inspiron 3000 system can be increased up to 144 MB by installing a combination of 16-, 32-, or 64-MB

3.3-volt (V) small-outline, dual in-line memory modules (SoDIMMs) in the two memory module sockets on the system board.

•Three power conservation modes— standby mode, save-to-RAM suspend mode, and save-to-disk sus- pend mode— which help you conserve battery power. If the batteries run out of power, save-to-disk sus- pend 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-V or 5-V PC Cards. 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.

•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 dis- kette from Dell or can be downloaded from Dell’s TechConnect BBS. See Chapter 5, “Getting Help,” for more information on Dell’s online services.

•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.

NOTE: If you need to connect an external diskette drive and you did not order a diskette drive cable with your computer, contact Dell to order the appro- priate cable. For information on contacting Dell, see Chapter 5,“Getting Help.”

•A PS/2-compatible touch pad that gives your com- puter full mouse functionality.

•An infrared port for use with compatible external devices. The infrared port permits file transfers with- out using cable connections. Fast infrared technology is also available.

•Universal Serial Bus (USB) capability, which can simplify connecting peripheral devices such as mice, printers, and computer speakers. The USB connector on your computer’s back panel provides a single connection point for multiple USB-compliant devices. USB-compliant devices can also be con- nected and disconnected while the system is running.

•On hard-disk drives with higher capacities, the Ultra DMA/33 data transfer protocol for the advanced technology attachment (ATA)/integrated drive elec- tronics (IDE) hard-disk drive interface. Ultra DMA/ 33 allows for data transfer rates of up to 33 MB/sec. Lower-capacity hard-disk drives have standard ATA technology.
