Monitoring battery power
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, 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 or Hibernation, 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.
