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.
