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 operating mode, which allows you to turn off specific devices, your computer
has three distinct power saving modes: System Idle, 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 5
percent, regardless of the power management setting you select. See your Software
guide, in "Controlling Power Management" for more information.
