Internal Batteries

The nine-cell Lithium-Ion (Li-Ion) battery provides the main power source in
your Versa SX computer. 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 Versa is
connected to AC power. The CMOS battery may discharge completely if the
Versa notebook remains unused for approximately two months.
Bridge Battery
The bridge battery 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 service technician can change a bridge battery.
