1-18 Getting Started
Battery Charging
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:
When the system is off or in Suspend mode and the AC
adapter is connected, charge time is approximately 2
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
Setup and Windows), and turn on the system. (Do not leave
any applications running.) Once the battery is fully dis-
charged, plug in the AC adapter and recharge the battery.
If you do not discharge the battery completely, it not only
fails to accept a full recharge, but also sends incorrect in-
formation to the Battery Gauge utility. The utility may indi-
cate that you have plenty of battery power when you
actually have very little. This can result in data loss when
the battery suddenly dies.
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.
NOTE
If you suspect that the battery is sending in-
correct information to the Battery Gauge utility, fully
discharge and recharge your battery three times.
This corrects the reading.
