Internal Components

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

Hard Disk Drive

A standard 2.5-inch, 9.5 mm or 12.7 mm hard disk drive ships with the system.

File Bay

CPU Board

The CPU board is a rectangular-shaped board attached on the left of the main board. The CPU
board is part of a subassembly, which includes a heat sink and the CPU board.

Audio Board

The audio board provides the NEC Versa system with its audio I/O capabilities via a line-in
jack, headphone and microphone jacks. It is situated on top of the main board.

Main Battery

The twelve-cell Lithium-Ion (Li-Ion) battery provides the main power source in your NEC
Versa LXi computer. See Chapter 9 for a list of battery specifications. In addition to this battery,
the CMOS battery and bridge battery also provide system power.

CMOS Battery

This lithium battery 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, for example, date, time, drives, and memory. The
CMOS battery charges when your NEC Versa is connected to AC power. The CMOS battery
may discharge completely if the NEC Versa notebook remains unused for an extended period of
time.

Bridge Battery

The bridge battery saves your system status in Suspend (Windows NT) or Standby (Windows 98
and Windows 2000) mode, giving you time to install a fully charged battery or plug in AC
power when your battery charge becomes low.
using it on battery power for the first time. Doing so insures that the bridge battery is fully charged
and that no data is lost during a battery change.
