2-10 System Configuration and Setup
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 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.
Connect your NEC Versa system to AC power for a full 24 hours before
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 a 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.
BIOS Setup
Your NEC Versa LXi computer comes with a hardware program called BIOS Setup that allows
you to view and set system parameters. BIOS Setup also allows you to set password features that
protect your system from unauthorized use.
Use BIOS Setup to:
!
set the current time and date
!
customize your operating system to reflect your computer hardware
!
secure your system with a password
!
balance your performance needs with power conservation.
Access the BIOS utility at power-on. Just press
F2
when the following prompt appears.
Press <F2> to enter Setup.
When you press
F2
to enter BIOS Setup, the system interrupts the Power-On Self-Test (POST)
and displays the current CMOS RAM settings.
