2-4 System Configuration and Setup
CMOS Battery
The system comes with a 3-volt lithium battery that maintains data 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 the system is connected to AC power. The CMOS battery may
discharge completely if the system remains unused for approximately two months.
Using the Primary Battery
The Versa TXi notebook comes with a rechargeable 3-cell Li-Ion primary battery that’s easy to
install and remove.

taskbar, an electrical plug displays when the system is connected to an AC power source or a
battery icon displays when the system is not connected to an AC power source.
Use the system’s power meter to determine battery status. Access the system’s power meter in
