5HDG 7KLV )LUVW A prerequisite for using this manual to service Dell computer systems is a basic knowledge of IBM®-compatible PCs and prior training in IBM-compatible PC troubleshooting techniques. In addition to information provided in this manual and the User’s Guide that came with the system, Dell provides the Diagnostics and Troubleshooting Guide for troubleshooting procedures and instructions on using the Dell diagnostics to test the computer system.
&+$37(5 6\VWHP 2YHUYLHZ This chapter provides an overview of the features and specifications of the Dell® Latitude® CP and CPi portable computers. 6\VWHP )HDWXUHV In addition to the standard features found in a Dell portable computer, the Latitude CP and CPi include the following new features: A Mobile Intel® Pentium® II microprocessor 233, 266, or 300 MHz or an Intel Pentium microprocessor with MMX technology 166, 200, or 233 MHz, with 32 KB of internal cache.
Two power management modessuspend mode (or standby mode in Windows 98) and suspend-to-disk modethat help you conserve battery power. Automatic thermal management that slows the microprocessor or starts a small fan when necessary. An infrared port compatible with IrDA 1.1 (Fast IR) and 1.0 standards, and a USB connector that supports stand-alone and hub devices. A PC Card slot with two connectors that support 5-V and 3.3-V PC Cards.

The following subsections describe the functions of these indicators. 3RZHU ,QGLFDWRU The power indicator is a green LED.
The system supports two low-battery warning codes: The first low-battery warning occurs when the main battery has 15 minutes or less of charge remaining. The amber battery indicator blinks once per second. The second low-battery warning occurs when the main battery has 5 minutes or less of charge remaining. The amber battery indicator lights up without blinking. If no user activity occurs within 15 seconds, the system automatically enters suspend (or standby mode for Windows 98) or suspend-to-disk.
