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.

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 or the hard disk.

System Suspend Mode

The computer saves the current state of the system in RAM and switches

off power to the CPU. The amber power indicator light flashes in this

mode.

To activate System Suspend mode

Press Fn+Esc, or slide the power switch forward and release it

immediately. You can also use the PowerPanel utility to enter System

Suspend mode.

To return to normal mode

Press any key.

System Hibernation Mode

The state of the system is saved on the hard drive and power is turned off.

The power indicator light is off in this mode.

To activate System Hibernation mode

Press Fn+F12. The “Save to Disk Manager” screen appears, and then the

computer enters System Hibernation mode. You can also use the

PowerPanel utility to enter System Hibernation mode.

✍

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.
