Main Battery; Cmos Battery; Bridge Battery; Optional Battery - NEC Versa LXi Series Service And Reference Manual

Main Battery

The twelve-cell Lithium-Ion (Li-Ion) battery provides the main power source in your NEC
Versa LXi computer. See Chapter 7 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 95) or Standby (Windows 98)
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.

Optional Battery

The NEC VersaBay III Battery Pack provides an optional, second Lithium-Ion (Li-Ion) battery
to use in your NEC Versa computer. Inserting a second fully charged battery increases battery
life for your notebook computer.
