Power management features
To reduce power consumption, the computer has three
power management modes: standby, suspend, and
hibernation.
Standby mode:
In standby mode, the following
occurs:
The LCD backlight turns off.
The hard disk drive motor stops.
The speaker is muted.
Note: Standby mode in Windows 98 is called

mode and resume normal operation, press any key.
Suspend mode:
When the computer enters suspend

in standby mode:

You can cause the computer to enter suspend mode by

Press Fn

program.
In certain circumstances, the computer goes into suspend
mode automatically:
If a “suspend time” has been set on the timer, and the

TrackPoint, the hard disk, the parallel connector, or
the diskette drive within the time set.
If the ac adapter is plugged in.

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.)
