1-20 Getting Started
Your actual operation time on a single battery charge may
vary significantly, depending on the intensity of system us-
age.
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. Use the power management features enabled
through Setup to extend battery life. See “Using Power
Management” in Chapter 3 for details.
Battery Charging
The time to completely recharge your main battery should
be about the same, no matter if the system is powered "on"
or powered "off," as follows:
for NiMH batteries — approximately 4 hours.
for Li-Ion batteries — approximately 3 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.
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.
