1-12 System Overview
Internal Components
Review the following sections for a description of the system’s internal
hardware.
Battery Pack
The system uses a rechargeable Lithium-Ion (Li-Ion) battery as its transient
power source. The battery pack installs in the compartment next to the
VersaBay III on the bottom of the Versa.
Hard Disk Drive
A standard 2.5-inch 9.5 mm (2.1-GB or 3.2-GB) hard disk drive ships with the
system.
VersaBay III
A 24X CD-ROM reader, a Diskette drive, a SuperDisk drive, or a DVD-ROM
drive comes installed in the VersaBay III on the right side of the system.
CPU Board
The CPU board is a rectangular-shaped board located above the main board.
The CPU board is part of a subassembly, which includes a heat sink and the
CPU board.
CMOS Battery
The lithium battery (3 Volts, 30 mAh capacity) is attached to P13 on the main
board. It provides battery backup and prevents data loss in the system’s
complementary metal oxide semiconductor (CMOS) RAM. This memory area
contains information on the system’s configuration like date, time, drives, and
memory. The CMOS battery lasts approximately three years.
Bridge Battery
The bridge battery saves the memory contents and system status for up to 5
minutes while in Suspend mode. It is connected to the main board via connector
P11. The AC adapter maintains voltage in the bridge battery when the system is
powered on or off. The bridge battery stores 7.2 Volts, 40 mAh.
