CHAPTER▼ THREE
BATTERY POWER & POWER
MANAGEMENT
In this chapter, you will learn the
fundamentals of power management and
how to use it to achieve longer battery life.
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
Lithium-Ion Battery
Your notebook uses a four-cell (or six-cell) Lithium-Ion
battery pack that provides power when you don’t have
access to an AC outlet.
