power management modes: screen blank, standby, and

hibernation.

1. If you press Fn+F3, or if the time set on the “LCD off

timer” in IBM BIOS Setup Utility expires,

v The LCD backlight turns off.

v The hard disk drive motor stops.

v The speaker is muted.

If you are using the ACPI operating system and you

press Fn+F3,

v The LCD backlight turns off.

v The hard disk drive motor stops.

If the time set on the “Turn off monitor” timer in the

operating system expires,

v The LCD backlight turns off.

To end screen blank mode and resume normal operation,

press any key.

Standby mode

When the computer enters standby mode, the following

events occur in addition to what occurs in screen blank

mode:

v The LCD is powered off.

v The hard disk drive is powered off.

v The CPU stops.

To enter standby mode, press Fn+F4.

Note: If you are using the ACPI operating system, you can

change the action of Fn+F4.s

In certain circumstances, the computer goes into standby

mode automatically:

v If a “suspend time” has been set on the timer, and the

user does not do any operation with the keyboard, the

TrackPoint, the hard disk, the parallel connector, or the

diskette drive within that time.

v If the battery indicator blinks orange, indicating that the

battery power is low. (Alternatively, if Hibernate when

battery becomes low has been selected in the “Power

Management Properties” window, the computer goes

into hibernation mode.)

To cause the computer to return from standby mode and

resume operation, do one of the following:

v Press the Fn key.
