Using Power Saving Modes
When you use a battery as the source of power for your computer, you
can take advantage of power management settings to conserve battery
life. In addition to the normal operaHng mode, which allows you to turn
off specific devices, your computer has two distinct power saving modes:
System Suspend and System Hibernation. When using battery power,
you should be aware that the computer automatically enters System
Hibernation mode when the remaining battery charge drops below 7%,
regardless of the power management setting you select.
Normal Mode
This is the normal state of your computer when it is in use. The green
power indicator light is on in this mode. To save power, you can turn off
a specific device such as the LCD or the hard disk.
