and 104°F (0°C to 40°C).
For directions on getting a detailed battery status, see the section, “Determining Battery Status.”
Determining Battery Status
Your NEC Versa system provides tools to help you keep track of the main and secondary battery
power level. If your system is configured (default setting) to display the power icon on the
taskbar, an electrical plug is displayed 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
the following ways:
!Move the cursor over the power icon on the taskbar to display the remaining battery
power for the system’s main battery.
