■ chapter 3 battery power & power management

In this chapter, you will learn how to operate your notebook on

battery power, how to handle and maintain the battery pack, and
learn about the system’s power saving features.

TFT display, central processor, hard disk drive are the major
hardware subsystems that consume the most power. Power
management deals how these key components should behave to
conserve power . For example, you can have the system turn off its
display after 2 minutes of inactivity to save power. Efficient power
management can help you work longer sessions before having to
recharge the battery.

The Battery Pack

Your notebook uses a six-cell Lithium-Ion battery pack
that provides power when you don’t have access to an
AC outlet.

It is necessary that you charge the battery pack for at least 6

hours before using it for the first time.

Note: In the Standby Suspend mode, a fully charged battery loses its

power in roughly 1/2 day or less. When not being used, the battery’s
power will deplete in 1-2 month.
