System Overview
The Dell® Latitude® LM P-100SD and LM P-133ST are high-performance multimedia portable computers that use the Intel® Pentium® microprocessor. This chapter provides an overview of the components and subsystems of these computers.
The individual model names within the Dell Latitude LM portable family indi- cate the type and operating frequency of the microprocessor and display used in the computer. For example:
•The Dell Latitude LM P-100SD contains a 100-MHz Pentium micro- processor and an SVGA (S) dual-scan (D) STN LCD.
•The Dell Latitude LM P-133ST contains a 133-MHz Pentium micro- processor and an SVGA (S) active-matrix (T) TFT LCD.
System Features
In addition to the standard features found in IBM® -compatible portable com- puters, the Dell Latitude LM includes the following new and/or advanced features:
•8 MB of nonremovable main memory on the main board. The memory capacity can be increased up to 40 MB by installing a matched pair of
4-, 8-, or 16-MB memory modules in the memory upgrade sockets on the main board.
•An 11.3-inch dual-scan SVGA color display or a 12.1-inch active-matrix SVGA display.
•42-WH lithium ion battery (nine cells).
•256-KB SRAM level-2 external cache and 16-KB internal cache.
•NeoMagic 2070 video controller supporting all video features with a PCI local bus.
•Intel 430MX PCIset for system and PCI controller.
•Built-in microphone and jacks for connecting external speakers, micro- phones, and headphones.
•Two new diagnostics tests (infrared and audio).
•An options bay that lets users replace the secondary lithium ion battery or diskette drive without turning off or rebooting the computer. This feature is sometimes called hot swapping. The CD-ROM can be inserted or removed while the computer is in suspend mode. This feature is sometimes called
