Using Power Saving Modes

When you use a battery as the source of power for your computer, you can use

the 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: Standby and Hibernate. When using battery

power, be aware that the computer automatically enters Hibernate mode when the

remaining battery charge drops below 5 percent, regardless of the power

management setting you select.

Normal mode

Normal mode is the normal state of your computer when it is in use. The power

indicator 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 drive.

Standby mode

In Standby mode the computer saves the current state of the system in RAM and

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

To activate Standby mode

1 Press the key combination Fn + Esc.

2 Press any key to return to normal mode.

Hibernate mode

In the Hibernate mode, the state of the system is saved on the hard drive and

power is turned off. The power indicator is off in this mode.

✍ If the battery level falls below 10 percent, you should either attach the AC adapter to

recharge the battery or turn off your computer and insert a fully charged battery.
