Component Features

Review the following sections for a description of the system's internal components.

Primary Battery

The system comes with a rechargeable 3-cell or an optional rechargeable 15-cell Li-Ion battery
as its transient power source. The 3-cell battery pack installs in a compartment on the bottom of
the system. The optional 15-cell battery pack fits under the system, and plugs into the battery
bay on the rear of the system.

Secondary Battery

An optional rechargeable secondary Li-Ion battery can be installed in the VersaBay IV slot on
the right side of the system.

CMOS Battery

The system comes with a 3-volt lithium battery that maintains data in the system's
complementary metal oxide semiconductor (CMOS) RAM. This memory area contains
information on the system's configuration (for example date, time, drives, and memory).
The CMOS battery charges when the system is connected to AC power. The CMOS battery may
discharge completely if the system remains unused for approximately two months.

A standard 2.5-inch, 9.5 mm hard disk drive ships with the system.

ROM Drives

A 24X CD-ROM drive, a 8X DVD-ROM drive, a CD-RW drive, or a combination CD-RW and
