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 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
percent, regardless of the power management setting you select. See your Software
Guide in Controlling Power Management for more information.
If you press the power button and hold for more than four seconds, the computer will switch off automatically.
When the computer is in System Suspend or System Hibernation mode, you cannot insert a disk.
When returning from System Hibernation mode, the system status stored on the hard disk is erased and the
computer starts normally if you slide the power switch and hold for more than four seconds.
If the battery level falls to below
10 percent, you should either
attach the AC adapter to
recharge the battery or shut
down your computer and insert
a fully charged battery.
