Power Saving Modes

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, 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.

✍If the battery level falls 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.

Normal Mode

Normal mode is the normal state of your computer when it is in use. The power indicator light displays green when your computer is in this mode. To save power, you can turn off a specific device such as the LCD or the hard disk.

System Idle Mode

Use the System Idle mode when your computer is not in use for a brief period. Selecting this option places your hard disk and video display in a low power state, and the CPU clock and processor stop. The power indicator light is umber in this mode.

To activate System Idle mode

To activate System Idle mode, press the key combination Fn+S, or use the PowerPanel utility to activate the System Idle mode.
