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%, 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.
System Idle Mode
This mode is convenient if you do not need to use your computer for a
brief period. The hard disk and video display enter a low power state,
and the CPU clock and processor stop. The power indicator light is red in
this mode.
To activate System Idle mode
Press Fn+S, the PowerPanel utility, or the Jog Dial™ control.
To return to normal mode
Press any key or touch the touchpad.
✍
If the battery level falls below 10%, you should either attach the AC adapter to recharge the
battery or shut down your computer and insert a fully charged battery.
