Battery Disposal; Internal Batteries; Cmos Battery; Bridge Battery - NEC Versa 2700 User Manual

Battery Disposal

Before disposing of the battery, put adhesive tape on the
terminals. Depending upon the NEC Versa model, the main
battery is made of Nickel Metal-Hydride (NiMH) or
Lithium-Ion (Li-Ion).
Contact your local waste management officials for infor-
mation regarding environmentally sound collection, recy-
cling, and disposal of batteries.

INTERNAL BATTERIES

The Nickel Metal-Hydride or Lithium-Ion battery is the
main power source in your NEC Versa computer.
Appendix B lists battery specifications. In addition to the
main battery, the CMOS battery provides power to
maintain system configuration settings and the bridge
battery provides power for up to 5 minutes while the main
battery is being replaced.

CMOS Battery

This 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 lasts approximately two
years. An authorized NEC service technician can replace
the CMOS battery for you.

Bridge Battery

An internal bridge battery in your system saves your system
status in Suspend mode for up to five minutes. This gives
you time to install a fully charged battery or plug in AC
power when your battery charge becomes low.
Only an authorized dealer can change a bridge battery.
