2-8 System Configuration and Setup
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 Standby (Windows 98/2000) or Suspend
(Windows NT) 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.
BIOS Setup
Your NEC Versa SXi 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 BIOS 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.
If the system detects an error during POST, it prompts you with a double beep and a message:
“Press <F1> to resume.” If you press
F1
, the system enters BIOS Setup automatically. If you
want to fix the error, carefully read the error message that appears above the prompt (taking
notes if you want), and press
F2
. You will see this message if your CMOS battery becomes fully
discharged.
