Conserving battery power
How long a fully charged battery pack lasts when you are
using the computer depends on a number of factors, such
as:
❖
How the computer is configured
❖
How much you use the internal storage drive, optional
external writable optical disc drive, or other optional
devices
❖
Where you are working, since operating time decreases
at low temperatures
There are various ways in which you can conserve power
and extend the operating time of your battery:
❖
Enable Sleep, which saves power when you turn off the
computer and turn it back on again
❖
Use the Windows power-saving option plans
These power-saving options control the way in which the
computer is configured. By using them, you can increase the
length of time you can use the computer before you need to
recharge the battery.
Microsoft has combined these options into preset Power
Plans. Using one of these power plans lets you choose
between maximum power savings and peak system
performance. You may also set individual power-saving
options to suit your own needs.
The following sections describe how to choose a Power Plan
and discuss each power-saving option.
