Conserving Battery Power; Charging The Battery - NEC VERSA VXi Service And Reference Manual

Conserving Battery Power

In the Windows 2000 environment, the default setting for a critical low battery state is Standby.
Standby does not power down the system to conserve battery power.
NEC Computers recommends changing the Windows 2000 Standby default setting for a critical
low battery state to Hibernate to prevent data loss during battery-powered system operation.
The power management state, Hibernate or Save-To-File (STF), saves the system's current
working environment to the system's hard drive, then powers down the system to conserve
battery power. You can configure the power management settings to enter hibernation when the
system reaches a critical low battery state.

Charging the Battery

Charge time depends on whether or not the system is being used. There are two ways to charge
the battery while it is installed in the NEC Versa VXi.
When the system is off or in Suspend mode and the AC adapter is connected, charge time is
!
approximately 3 hours.
When the system is powered on and the AC adapter is connected, charge time is
!
approximately 4 hours.
For maximum battery performance, fully discharge the battery before recharging it. To do so,
unplug the AC adapter, turn off power management features (through BIOS Setup and Windows
power management), and turn on the system. Once the battery is fully discharged, plug in the
AC adapter and recharge the battery.
The warning beep that sounds when battery power becomes critically low is always a true
indicator that battery power is low. Be sure to save data when you hear the beep and take proper
steps to provide power to the system.
