1-20 Getting Started
Extending Battery Life
While on the road, it is important to be aware of the simple things you
can do to extend the life of the system’s main battery. Turning down the
screen brightness (
Fn + F9
)
and contrast (
Fn + F11
)
extends battery life.
Press
Fn + F7
to toggle through different power management modes and
extend battery life. Chapter 3 “Using Setup and Power Management”
gives details about power management features and the modes available.
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 Note:
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 (
Fn + F7
) and Windows
power management), and turn on the system. Once the battery is fully
discharged, 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 information to the Battery Gauge
utility. The utility may indicate 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.
