Charging The Battery; Battery Precautions - NEC VERSA VX Manual

Charging the Battery

Charge time depends on whether or not you are using the system. There are two ways
to charge your battery while it is installed in the NEC Versa VX:
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 your data when you hear the
beep and take proper steps to provide power to your system.
